Welcome at the FOSSASIA Summit!

13:05 - 13:15

FOSSASIA summit had helped brought awareness of Open Source technologies to the general public and enabled collaboration between professionals in the area of ICT (Information & Communications Technology). Echoing the Singapore Government’s focus in the developing Singapore's E-commerce and digital economy, organisations such as FOSSASIA plays an important role as the melting pot for businesses, software developers and government agencies to innovate ICT solutions. Open Source technology can benefit local businesses and workforce. FOSSASIA summit 2018 will cover emerging technologies such as Natural Language Processing using Artificial Intelligence and Distributed technologies like Blockchain, thereby opening up new digital frontiers for Singapore SMEs (Small and Medium enterprise), workforce development, and Public services. Only because the code is open we are able to talk about it. Open code is a wonderful present to the community. 

13:30 - 13:50

Daimler uses Free and Open Source software within several of its products and thrives to support and collaborate with the Open Source community. Automakers are becoming software companies, and just like in the tech industry Open Source is the way forward. At the keynote Daimler will outline its engagement in the Open Source community and plans for the future. Daimler is the first German automaker that joined the development of Automotive Grade Linux to help build the next generation connected car platform. The company is also a member of the Linux Foundation and Hyperledger. 

15:05 - 15:20

The FOSSASIA developer network is one of the largest communities in the Open Source world today and we are proud to have a positive impact and improving people's lives with Open Technologies. It took us years to develop approaches and processes to scale projects and we are constantly reviewing and working hard on improving ourselves. So, what is next?

What do we want to do next, what do we want to do better and how do we want to help more people, train developers, create better software and hardware and do good?

We came up with three areas, that we want to focus on:

1. In 2018, it is our goal to improve the quality of work of the FOSSASIA organization and contributions in our projects. We believe that the way to move forward is to provide project owners with more responsibilities and ownership. We aim to develop more and more into an organization that provides a framework for projects. Therefore we will continue to develop programs like Codeheat, OpenTechNights, organize meetups, participate in GSoC and GCI. We also plan to cooperate more with other organizations. Why shouldn't we run the OpenTechNights at events around the world and help to bring people together? Why shouldn't we have more OpenTechSummits with partners in China, India and Vietnam?

2. We have made very good experience with our best practices. We have seen that newcomers can progress very fast if they feel welcome and receive help and guidance from others. After they become participants in our programs many contributors move on to support others as mentors. We also see that contributors have moved to large companies, but still continue to help others in the community. This is wonderful. We want to share our experience and inspire other projects. Therefore, we plan to participate in more events, we will set up a monthly live-cast and we will run a YouTube series on these topics. While a lot of traditional school education still encourages a top-down approach we will focus our attention even more on enabling the community to collaborate on an equal level and follow the idea of sharing ideas and code freely.

3. A question that any organization and project encounters over time is how to ensure the work and setup is sustainable? What settings do projects need to succeed? While there are many non-profit organizations out there developing Open Technologies and FOSS, we also see that many people are moving on to companies that often focus on proprietary solutions and prevent contributors from continuing their engagement in the Open Tech community due to financial reasons and to support their families. At the same time, we see many projects that would have a great potential to be Open Source and at the same time commercially successful. Therefore we are starting a new dedicated FOSSASIA Accelerator that is specifically for Open Source projects. We invite projects to apply for the accelerator and investors and companies to team up with us. And, think about it, while many startups these days start with an idea, Open Source startups already have a product before any investment has started. So, these are great opportunities!

The problems in this world are too big. There is a lot of injustice, we are destroying the environment and people are even fighting each others. At FOSSASIA we want to set an example of collaboration across borders and cultures. So, please join us and let's make this a success. I wish everyone a wonderful event full of sharing and new understandings. Let's get inspired to share and learn for each other to build a better world.

15:20 - 15:30

Codeheat (In the Heat of the Code) is an annual coding contest for FOSSASIA projects. The contest runs between September and January. Grand prize winners attend the FOSSASIA OpenTechSummit in Singapore and receive the award officially in an award ceremony.

15:30 - 15:40

16:00 - 17:55

The workshop will cover how to setup and create scientific experiments with the FOSSASIA PSLab or use it to measure electronic conditions in hardware prototypes. The Open Source Pocket Science Lab can be used through the desktop and phones. It combines different devices including an Oscilloscope, a voltmeter and several sensors. It is useful for startups, hobbyists and the educational sector. You can measure currents and all kinds of electronic devices and connections with the PSLab. Check your prototypes or do all kinds of electronic experiments.

Explore, tinker, play - learn how to create your very own retro pixelart games for the Arduboy, a tiny Arduino-based pocket-sized game console reminiscent of Gameboy's glory days. Best thing? Thanks to Clouduboy you can now do this entirely in your browser, all in JavaScript with the language and techniques you already know (and love)!

Requirements: The only thing needed is a PC/Mac with an up-to date browser and a USB-A port for flashing the microcontrollers. All software will be provided or will run in the browser. JavaScript-programming experience at this workshop is recommended, but Clouduboy's "Learn to Code!" tutorial itself is suitable for learners of any levels of programming experience (including people who never coded before).

Friday, 23rd Mar

09:31 - 10:26

A hands-on coding workshop with Google's interactive global scale data analysis tool BigQuery if you have never seen it before (but have a little experience with SQL ideally).

10:00 - 10:25

Nimbus is an exciting and experimental lightweight client for the Ethereum network that focuses on next-generation Ethereum technologies and running on resource-constrained devices, such as mobiles. During the talk, we’ll go over a number of topics:

  • Anatomy of an Ethereum client

  • Sharding, and what it means for the implementation

  • A little bit about Nim, the language it’s implemented in

  • Status Open bounty - get rewarded for your OSS contributions

The Open Source label was born in February 1998 as a new wayto popularise free software for business adoption. OSI will celebrateits 20th Anniversary on February 3, 2018, during the opening day ofFOSDEM 2018. The presentation will summarize the evolution of opensource licenses and the Open Source Definition (OSD) across two decades,explain why the concept of free open source software has grown in bothrelevance and popularity and explore trends for the third decade of opensource.

10:30 - 10:55

Cryptocurrencies have there own APIs expose for developers to access. RPC (Remote Procedure Call) is the easiest way among those APIs. It works as a Restful API for the blockchain network. Using those APIs you,

  • Check the wallet balance
  • Validate Transactions
  • Do Transactions
  • etc

You can do what ever the blockchain work you want with those APIs. So in my talk I will talk about how to use those APIs to connect to most famous Bitcoin & Ethereum networks. So you can programmatically do transactions & everything.

We will discuss the lessons we have learned with containers so far, including how Google (and other internet scale companies) have been developing and using containers to manage applications for over decade. His session will address the old world of node first development vs. the new world of cloud native computing; along with discussing properties of a cloud native computing architecture – container packaged, dynamically managed and micro-services oriented – and the benefits it can provide developers and end users.

Furthermore, we will cover the formation of the Cloud Native Computing Foundation (CNCF) along with the contribution of its first hosted project: Kubernetes.

10:30 - 11:55

In this workshop we will explore how Cloud Dataprep can help you to make the most out of your data by automatically detecting schemas, datatypes, possible joins and anomalies such as missing values, outliers, and duplicates. Profiling your data can be time-consuming, Dataprep helps you to save that time and go right to the data analysis. You can plug your solution into Cloud Dataprep as it is serverless and works at any scale.

11:00 - 11:25

Among all animals, only humans show the curiosity for swapping and exchanging goods. This gave birth to the idea of trade which enabled large spread collaboration and pole vaulted us to spread innovation, goods and services globally. 

In this talk, let's explore how energy and commodity trading firms are viewing technologies such as blockchain, smart contracts, robotic process automation, cloud computing, open source & artificial intelligence to build the next generation of trading organizations. We'll look at the impact it would have on the skill sets required by future traders and how "brain-power" (intuition) and "computing-power" (mechanics) could work together in seamless harmony,  orchestrated together perfectly like Beethoven's 9th Symphony.

Are you worried about how you can pay bills if you spend your time developing free and open-source software (F/OSS)? Can it be done profitably?

Ways to make money from the creation of closed software are well understood and widespread, most notably through:

  • selling copyright licenses to end customers who will run the software on their own computers; and
  • running the software on the developer's own computers and then either charging users for access, or providing users with access for free and charging customers for users' attention.

For developers who would like to make money developing free and open-source software (F/OSS) - whether as employees or as entrepreneurs - it is tempting to try to start with one of these models and stretch it to fit, however neither of these models is even remotely suitable for F/OSS because both start by denying fundamental freedoms to share, modify, or even access the software's source code. It is easy to forget that neither of these models was obvious at the dawn of computing; they both had to be invented, and they're not the only ways to do it. The good news is that developing F/OSS is not intrinsically incompatible with making a living, people have been doing it for decades. The really great news is that dozens of ways of doing it have now been developed and widely used. This panel will explore several specific examples with panellists from quite different backgrounds.

11:30 - 11:55

In this talk, Gaurang Torvekar, the co-founder and CTO of Attores and Indorse will speak about his experience in the blockchain industry, especially Ethereum over the last two years. Attores has been working with Ngee Ann Polytechnic for issuing their diplomas on the blockchain, while Indorse is building a decentralized professional social network. Gaurang will speak about how Blockchain is revolutionizing the education industry and the trends in the space over the years

13:00 - 13:25

GNU/Linux has a handy lscpu command which can print CPU information of current system while BSDs lack, so I decide to develop one used in BSDs. The whole task takes about 2 weeks and is divided into following parts:

(1) Study BSD program structure and sysctl APIs;

(2) Refer Intel/AMD specs to implement function;

(3) Test the program: thanks to kind people who help test on AMD architecture, different BSD flavors, and create ports.

In this topic, I want to share the experience and lessons of developing first application for BSDs

13:00 - 13:55

Blockchain is a hyped technology. We want to know what are real use cases of Blockchain apart from the hype. The panelists will provide insights into their projects and plan for using blockchain. Most “blockchains” are using Free and Open Source (FOSS) infrastructure to mine and run their network. What is the role of Open Source in the projects and companies of panelists? How does the Open Source ecosystem benefit from the trend to blockchain technology? FOSSASIA’s goal is to improve people’s lives with Open Tech. Technologies like blockchain raise questions about the impact on people and the world. It takes a lot of energy to generate blockchains and there is no immediate benefit except of a coin itself. There is no immediate value, product or anything a human could use except for the transactional value. What should be the stake of a socially responsible organization in regards to these questions? And does the value of technology outweigh its cons? Can Blockchain solve world problems and which ones?

13:00 - 14:25

Extract, Analyze & translate Text from Images with Cloud ML APis. Topics of this session are: Vision + NLP + Translation APIs

13:30 - 13:55

While the Intel x86-64 architecture is undisputedly market leader in the server space, several vendors have started introducing ARM64 boards. This presentation examines the suitability of ARM64 server boards for network servers. In particular, we look at the workload of a moderate-size ccTLD DNS zone (.dk) and how it would perform on ARM64 running FreeBSD.

We consider the viability of the ARM64 platform from performance and performance/power perspectives. While ARM64 is definitely slower than Intel on many workloads, it performs at least as well or better than Intel on workloads that are interesting to the internet community. Notably DNS is a very appropriate workload for ARM64.

14:00 - 14:25

KVM, kernel based virtualization, turns the Linux kernel into an

hypervisor to provide full virtualization services. There is great deal

of work that happens in the background to create a guest environment

and provide various services securely.In this session we'll peek into the background to understand

how a KVM x86 guest environment comes to be, how/where do various

emulated peripherals fit in and how do they interacts with each-other,

the hypervisor and the hardware.

We'll also see examples of the the KVM Virtualization deployments

and the value it has brought to businesses.

14:00 - 14:40

Cryptocurrencies have captured the imagination of technologists, financiers, and economists. Perhaps even more intriguing are the long-term, diverse applications of the blockchain. By increasing transparency of cryptocurrency systems, the contained data becomes more accessible and useful.The Bitcoin blockchain data are now available for exploration with BigQuery. All historical data are in the big query-public-data:bitcoin_blockchain dataset, which updates every 10 minutes. We hope that by making the data more transparent, users of the data can gain a deeper understanding of how cryptocurrency systems function and how they might best be used for the benefit of society.

14:30 - 14:55

Tablet devices are too attractive mobile computer devices,they are inexpensive, lightweight, display, touchscreen, battery and more. They can buy only US$ 40~ now (only used Tablets). But they can use iOS, Android, Windows only.No Linux Distributions on Tablet. New generation peoples doesn't have to need and want to use traditional computer? Smartphones and tablets are necessary to use Linux Distributions for new generation peoples. I feel that it will become an era when it is difficult for new generation peoples to use desktop Linux.

In this session, I will talk about 「Install and use Intel ATOM Tablet,UMPC and install grub2 bootloader on Linux」.The Linux kernel evolved rapidly from Kernl 4.9LTS to 4.14LTS.Recently Linux Kernel has evolved rapidly on x86 ATOM devices, Tablet, Stick PC, Apollo-Lake devices, UMPC GPD-WIN and GPD-Pocket. A lot of mobile devices can use ubuntu, fedora,openSUSE, Arch Linux, and others now! Let's install Linux on Tablet and any mobile devices.

14:40 - 15:20

Anyone can easily analyze the more than five years of GitHub metadata and 42+ terabytes of open source code. We’ll leverage this data to understand the community and code related to any language or project. Relevant for open source creators, users, and choosers.

14:45 - 16:15

We will explore examples of business that have adopted TensorFlow and Cloud ML to solve their real-world problems: a cucumber farmer in Japan who was able to build a deep learning-based cucumber sorter by himself, a used car auction service using TF for classifying car models and parts, and a food manufacturer that has been able to increase productivity significantly in their baby food factory.

15:00 - 15:25

Developing massively parallel systems is restricted by the complex tasks which need to be managed by the programmer. GPU computing provides the opportunity to parallelize data parallel algorithms while CPU can run the sequential code. With increasing algorithmic development, some new algorithms require iterations of parallel computation on the GPUs (computation scale larger than GPU memory) while some require multiple different data parallel algorithms to run simultaneously, which are notorious to be managed by the programmer.

HPX is an open-source, general purpose C++ library for developing parallel and distributed applications with a broad community usage. This talk aims to discuss the development of HPX Compute language (HPXCL) API for the integration of GPU computation with asynchronous many task execution library HPX. Asynchronous functions are provided for kernel launch, kernel execution and data transfer with the capability to hide the communication latency through computation. To give an example, computation on multiple CPU nodes, GPU nodes can all occur in parallel and can be synchronized when the results are required by the user. This system unleashes the potential to take computation to the exa-scale level.

This development is currently spearheaded by the Stellar Group Community which is a consortium of global researchers. The presenter has been a contributor to this community since his Google Summer of Code participation in 2017.

Why should you use Kubernetes, an Istio Service Mesh or any choreographed Microservice architecture? There is the efficiency argument, scaling, time to market. There is the isolation argument, resilience. But in this talk, we share a different perspective: Our systems are becoming polyglot, intelligent, and rapidly moving towards an evolutionary mode where machine learning is a natural collaborator in the design thinking and coding process. Let’s play with that idea.

15:30 - 15:55

Meilix Generator is a new tool to build your own custom Internet kiosk for your business. For convenience the kiosk is based on linux and runs with the lightweight LXQT desktop environment.

16:00 - 16:25

An internet kiosk is a special use case. A single computer is shared by an indefinite number of users. Lots of security concerns arise. In Asia and elsewhere multiple non-latin languages have to be supported. We decided to create a custom lightweight distribution, Meilix and a generator web app that allows you to preconfigure an ISO with the wallpaper and desktop settings in place.

16:00 - 17:55

The workshop will cover how to setup and create scientific experiments with the FOSSASIA PSLab or use it to measure electronic conditions in hardware prototypes. The Open Source Pocket Science Lab can be used through the desktop and phones. It combines different devices including an Oscilloscope, a voltmeter and several sensors. It is useful for startups, hobbyists and the educational sector. You can measure currents and all kinds of electronic devices and connections with the PSLab.

16:30 - 16:55

Unikernel is a novel software technology that links an application with OS in the form of a library and packages them into a specialized image that facilitates direct deployment on a hypervisor. Comparing to the traditional VM or the recent containers, Unikernels are smaller, more secure and efficient, making them ideal for cloud environments. There are already lots of open source projects like OSv, Rumprun and so on. But why these existing unikernels have yet to gain large popularity broadly? We think Unikernels are facing three major challenges: 1. Compatibility with existing applications; 2. Lack of production support (e.g. monitoring, debugging, logging); 3. Lack of compelling use case; 4. Lack of standard to Unikernels. In my presentation, I will review our investigations and exploration of if-how we can convert Linux as Unikernel to eliminate these significant shortcomings, where I name this as UniLinux, and some potential but valuable use cases to Unikernels like IoT, Serverless and IO-intensive applications.

In this session, we will discuss the concept of serverless architecture, which is also called FAAS (Functions as a service). We will take a closer look at what this often confusing term means and how we can take advantage to create new generation solutions.

AWS Lambda being the most popular implementation (yet), we will look at a sample implementation, challenges and other concerns.

17:00 - 17:25

I am going to talk about why and how we moved from a single flask application to a decoupled application having separate API endpoints and frontend. I would also go through the entire server side codebase and explain how exactly to use the API endpoints.
10:00 - 10:25


It is impressive how much time and resources a team can save by using the OBS to manages their packages creation and distribution. OBS is a generic system to build and distribute packages from sources in an automatic, consistent and reproducible way. 

Andrew Lee will cover the benefits of using OBS, explain some of it features and workflow for all your packaging and releasing needs, like automatically build package from scratch on multiple target distros and architectures, easy access through QA to the developer's repo to generate new images with the changes for testing before integration into the production repo, vcs-like workflow as branch code, send merge requests and review submissions and flexible to connect additional resources to empower the backend worker(builders) even with different architectures. At the end tips on how to setup and optimize OBS will be provided.


The audience is anyone who interested in packaging and distribution development. Attendees can expect to learn how this tool can save your time and resources at a team work environment. And how to setup and optimize this tool as an infrastructure into your development framework and much more.

Benefits to the Ecosystem

This presentation will help existing and new software projects and independent software vendors better understand how to use morden infrastructure to maintain your packages and repositories for multiple distributions and architectures collaboratively. And will hopefully encourage more software projects and independent software vendors to use such infrastructure to provide repositories for user to keep track their updates easily, and for developers to collaboratively work and contribute easily to the packages and repositories.

This talk will talk about our experience with organizing Tech Jam for the last two years and using Tech Jam as an opportunity to get children as young as 10 in coding and hardware hacking. The programme is distingushed by two main features

1. Open ended creation using tech - Sessions are split between learning and hacking. With short bite sized learning, students are given more time and freedom to create projects

2. Mass learning: Each session caters to over 200 students. The large number of students creates an environment for busy and engaging work where students learn from each other and are motivated by example

We discuss the specific activities and also the methodology as well as tools that we are looking into for the future. 

Learn more about how the open event project uses JSON API, a specification for building APIs. JSON API follows the ‘Convention over Configuration’ philosophy. Aside from a brief introduction to the revamped architecture of the open event project, the talk will also discuss best practices followed for building APIs and URI conventions followed throughout the project. The talk will also shed some light on the challenges faced while implementing JSON API with Flask.

10:00 - 10:45

In this panel we will explore with industry experts how blockchain technologies, which aren't that new, but were made popular when Bitcoin suddenly hit the news, can be used to develop applications that, while leveraging the technology, go well beyond what people usually associate with blockchain, i.e. financial services. We'll look at notarization, voting, participative governments, community utilities, shared economies and services... We will discuss this with industry experts from the blockchain ecosystem, users and developers alike.

10:00 - 10:55

Hands-on workshop covering how to write SELinux policies for new applications as well as update existing policies. Will cover Reference Policy framework, more advanced policy analysis and tradeoffs with different ways to confine applications.

Apache Spark is one of the top big-data processing platforms and has driven the adoption of Scala in many industry and academic settings. As entire Apache Spark framework has been written in scala as a base, it’s real pleasure to understand beauty of functional Scala DSL with Spark.

This talk is intent to present :

  • Primary data structures (RDD, DataSet, Dataframe) usage in universal large scale data processing with Hbase (Data lake), Hive (Analytical Engine).

  • Case study: We will go through importance of physical data split up techniques such as coalesce, Partition, Repartition and other important spark internals in Scaling TB’s of data / ~17 billions records

  • Also, We will understand crucial part and very interesting way of understanding parallel & concurrent distributed data processing – tuning memory, cache, Disk I/O, Leaking memory, Internal shuffle, spark executor, spark driver etc.

It has recently become possible to build an AI system with cryptographic security guarantees, private training data and decentralized training procedures. That makes it possible to train ML / AI systems on highly sensitive datasets (such as those containing personally identifying information or medical data) while mathematically guaranteeing the preservation of privacy and security of said data. 

To make this possible, one needs to leverage recent advances in blockchain technology, homomorphic encryption and secure multi-party computation. The talk will introduce essential ideas from these diverse fields and provide and guide the listener through what's necessary to create secure, private and decentralized AI systems. We will also introduce key components of OpenMined, the leading open source project in this space, enabling developers to build practical decentralized AI systems.  


10:55 - 11:05

We are students from UWCSEA and we are the leaders of a group called Ethical Hacking wherein we nurture the interest of students in cybersecurity issues as well as learn about the cyber world and issues related to security. We have so far done CTFs and built servers and visited SUTD to learn more about this field and engage our understanding on the cyber world. 

11:00 - 11:25

With the development of the API server for the Open Event project we needed to decide which framework to choose for the new Open Event front-end. With the plethora of javascript frameworks available, it got really difficult to decide, which one is actually the right choice. Every month a new framework arrives, and the existing ones keep actively updating themselves often. We decided to go with Ember.js. This talk will cover the emberJS framework and highlight its advantages over others and  demonstrate its usefulness with some code snippets and UI screenshots,  as well as  show the hands on advantage by comparing it with the way the previous frontend was structured and the extremely efficient usage of resources using json api.

How sustainable is it do build open tech communities through coding programs, contests and hackathons? What is the experience of Google Summer of Code, Codeheat, Google Code-in, UN Volunteers, Hacktoberfest, 24PRs? What goals do programs have? Are they achieving the goal of advancing Open Tech projects? Panel with Hong Phuc Dang, Misako, Stephanie Taylor, Gi Soong Chee.

11:05 - 11:55

As the security landscape changes, especially in a cloud-based world, the biggest security threats shift away from physical machine access or VPN compromise toward emerging threats like improper software practices, social engineering attacks, or vulnerabilities in underlying libraries. This emerging threat model forces us to re-think traditional security practices in more modern and innovative approaches to intrusion detection and response.

This talk discusses the principles of modern security and how a free and open source tool - HashiCorp Vault - embodies and enforces the principles of modern security.

You may think rsyslog is just a little program with ugly config file. You may say it's only routing your syslog messages from journald to plain files. But rsyslog is real swiss-army knife of logging. I'll show you how good is rsyslog in modern world of ELK, containers and JSON logs. And how bad it can be when you've missed something. It may help you to process over 100k msg/s. Or it may break your production. And it may do some neat tricks for you as well!

Join us for the Database Lightning Talks!

In GSoC 2017, we in a team worked together and built the Open Event Frontend which is totally decoupled from the Open Event Server. Since Open Event is a vast ecosystem, we need to ensure that each and every contributor can set up the project locally for development and can proceed faster towards contribution. Thus, it sometimes gets difficult for beginners to set up the project. In this session, I will show how to set up Open Event Frontend and Open Event Server locally and make the frontend use the local server rather than online hosted version (heroku) so that new contributors can focus on contribution rather than spending their much time in setting up the project.

12:00 - 12:15

Real-time ingestion and analysis of data streams is advantageous for organizations handling clickstreams, logs or IoT data sources. However, moving from batch to stream processing has historically been difficult. With Google cloud platform and BigQuery, any organization from a small start up to a big company with huge data could implement an analytics system without concern about running infrastructure, scaling at a reasonable price. 

firefly is an open source micro framework to deploy Python functions as web services. firefly was created with the aim of simplifying the deployment Machine Learning models as RESTful API. But as fate would have it, it became our favorite tool for building microservices. firefly takes care of processing the HTTP requests, forwarding the data to the python functions and encoding the result back to an HTTP request. It also has data validation, authentication support, transferring any type of file. You can also define a configuration file specifying the URL resource structure resulting in an elegant RESTful API.

It comes with a client library that makes calling remote functions calling as easy as calling functions present locally. It is a WSGI application and can be deployed and scaled through any WSGI server like gunicorn. There are many other features in the pipeline like multiple authentication modes through the plugin system.

This talk will focus on introducing firefly, it's notable features like plugin support, building microservices efficiently with various examples.

The Education system is about 200 years old and inspired by organizational thinking of the Industrial Revolution and is arguable a bit out of date. With what we've learned building Open Source software and communities, can we apply the lessons learned to creating an inclusive growing up experience for kids that is not school based?
13:00 - 14:55

Participants will learn basics of Python and how it can be used to simplify/automate common tasks.

C is still by far the most popular programming language deployed around the world. The Linux kernel and most of a modern day Linux platform are built on C. It is the lingua franca we have, and knowing how to use it is useful for getting into Kernel work, Embedded, middleware and much more.

This workshop will cover the groundwork for C in a practical way, so you can use it to do something useful. C is actually a rather simple language and the trick is simply to think like a machine does.

Learn from someone with over 20 years of experience, and get started on what is still, despite its faults, a long-standing tool for creating operating systems and devices. This will be intended for people who have some familiarity with a programming language, but would like to learn the lower levels for the speed and access that come with it.

Bring a laptop and your favorite Linux distribution if you want to participate.

Daimler and Open Source

When you need to scale an application with a lot of data, how do you decide on a storage solution? How can you both safely store and efficiently interact with large data sets? This usually boils down to a choice between SQL or NoSQL -- but what if there was a third option?

In this session, developer Alex Shinn will discuss Indeed’s MPH-Table: an open source storage solution that uses minimal perfect hash functions to generate a fast and compact key/value store. Alex will discuss how we use MPH-Table at Indeed, what situations are ideal for it, additional optimizations it allows, and how it compares to alternate solutions. Attendees should enter with a fundamental understanding of existing scalable storage solutions, and will leave with a basic understanding of MPH-Table, when they might want to use it, and how other solutions compare.

  • Kubernetes is a very powerful, flexible and production-grade container orchestration system. However, with flexibility comes complexity and thereby verbosity in constructs. It’s hard for a developer to define the Kubernetes configurations as there is a huge learning curve. Developers need something simple that can easily define their micro-services. Right now Docker Compose gets closest to solving this problem.

If your production runs Kubernetes, how do you remove the disparity between the development and production setups? How do we get developers using Docker Compose to use Kubernetes? How well does Docker Compose map to Kubernetes?

Enter Kompose to the rescue.  The Kompose tool generates Kubernetes native configs from their Docker Compose files.

My talk will explain how Kompose solves developer’s problems and demonstrate its different features during the live demo.

The Internet today is plagued by many problems. From viruses and spam, to identity theft and piracy.We can solve those problems.With a virtual operating system that runs the cloud, using blockchains to secure identities and data, a virtual network layer to protect against unauthorized network access, and a virtual machine to sandbox untrusted code.This talk will describe Elastos, an Operating System for the smart web.It will explore the approach that Elastos takes to achieve these goals, and gives a vision of a possible future internet.

Since the launch of the website, there has been an increased traction about the concept amongst the competitive programmers that StopStalk ( has provided to them. StopStalk not only helps in analysing your own competitive programming progress but also helps to code and learn collectively with your friends. Along with the features that are provided on StopStalk I want to discuss the implementation details that are going on in the background to serve the beautified data on the website. The code is completely open source on Github

Also want to portray how the processing of data is done as the size of the dataset is tremendous and increasing day by day.

At the UNESCO Hackathon opening we are welcoming participants and introduce the goals and agenda of the hackathon.

The goal of the hackathon is to engage the community of developers to create open source apps and games that tackle climate change, environment and sustainable development challenges. We are specifically interested in applications and games that set an example for others who could replicate solutions in other countries, and in particular in the Mekong countries, to tackle the sustainable development challenges.

14:00 - 14:25

In this session, Keya looks at how animations can be applied to add style and substance to any webpage and how we can identify some common design patterns to add purposeful animations to our designs.

There are a  plethora of development tools available today, from declarative CSS Animations and Transitions to fully featured JavaScript animation libraries like GreenSock to develop slick animations, but there's an upcoming new option: the Web Animation API! 

Join in the fun as Keya demonstrates how simple animated micro interactions can be developed with ease using this new API combined with popular frameworks like React.

At Adjust, we produce near-real-time analytics on over 400TB of high velocity data.  This talk is a brief introduction to how we do it, and it serves as a showcase for what PostgreSQL is capable of doing in a big data environment.

This talk will be of interest to people looking for information about how open source databases can be used at massive scales, approaches to federated data, and general open source success case studies.

Following the first wave of cloud adoption, moving from private data centers and on-premises hosting to cloud infrastructure platforms such as AWS and GCP, we're now seeing a second wave of adoption where self-managed and operated database and messaging services are being replaced by managed cloud database services like RDS.Many of the most popular and longstanding Open Source database systems such as PostgreSQL and MySQL are available in these Database-as-a-Service platforms.  However, newer technologies used used for building scalable data pipelines are commonly proprietary, locking you into a single cloud provider and out of the vast Open Source innovation ecosystem.We'll look into into their Open Source alternatives, such as Apache Kafka and ScyllaDB and compare them with their proprietary cloud service counterparts.

Blockchain governance is perhaps the biggest factor that explains the current state of things and can be used to guide evolution of blockchain. Blockchain governance, like any similar governance of a complex system, consists of components, including incentives, communication, compliance and failure management. Optimizing each and every one of these factors will give the blockchain governance its best shot to become mainstream, revolutionary and disruptive to almost any industry in the world.

The growth in the development of applications using open source APIs and frameworks has created complexity with endless unmaintainable endpoints. This session will focus on my findings in building a NodeJS backend application which leverages on GraphQL and MongoDB as the database. GraphQL offers multiple functionalities in a single endpoint to communicate with front end services. In addition, I will share the advantages and disadvantages of GraphQL and how it is different from REST API. I hope this session will help you to get started in exploring this technology.

14:30 - 15:25

Terraform allows developers to manage infrastructure resources in a rather predictable way but it is not always that easy. Let’s walk through real-life challenges when building secure delivery pipeline using Terraform and open-source tools on AWS.

14:40 - 14:50

For many years humans have been sending probes out to space, but less than 5% of our planet’s defining trait, oceans, have been explored, and it’s not because nobody’s interested. Daniel and Michael talk about some of the problems that come about when trying to put electronics where it should not be, and how they got around them on a budget to build their own AUV, Magni. Through their talk, they hope to spark interest in a rather niche field of robotics.

14:50 - 15:00

Projectile launchers are cool and electromagnetic ones even more so. For decades many have been fascinated by them and with the US and Chinese Navy putting railguns on their ships, they have never been more exciting.

The session will also provide you the guidelines to start contributing to Open Event Webapp. 

PL/R is a PostgreSQL extension that allows the use of R from within PostgreSQL for advanced analytics in a simple, efficient, and controlled manner. It has been available and actively maintained since January 2003. PL/R works with all supported versions of PostgreSQL, and all recent versions of R. It is used by thousands of people worldwide.

Recent trends in big data favor bringing the analytics closer to the data – meanwhile PL/R has been quietly providing this service for over 15 years! This presentation will introduce the audience to PL/R, discuss the pros and cons of this approach to data analysis, take them through basic usage, and finally illustrate its power with a few advanced examples.

15:00 - 16:55

Participants will learn how to develop and deploy a CRUD web app using Python, Flask and web technologies.

Traditionally in classroom, math has been taught using chalk-blackboard fashion. With the advent of technology, some teachers started using multimedia, especially graphics/animation to explain students the different mathematical phenomena. But I strongly believe, if students could code themselves, it would be much more helpful for them to internalize mathematics - from very basic to advance stuffs. In this workshop, I am going to show some simple python programs that students (grade 6 to grade 10) can write which helps them to understand different mathematical concepts.

15:00 - 21:51

Create open source apps and games that tackle climate change, environment and sustainable development challenges, and win awesome prizes! We are specifically interested in applications and games that set an example for others who could replicate solutions in other countries, and in particular in the Mekong countries, to tackle the sustainable development challenges. It is our goal to engage the developer community to develop innovative applications as open source by leveraging the open data and knowledge available.

15:30 - 15:55

Developers are constantly searching for the best. They seek the best language to code in, the best tools to use, and they are always looking for what is at the forefront of development. Django as the web framework of your project is the best way to turn your idea into business reality. Perhaps you’ve heard of Instagram, Pinterest, Disqus, Rdio, OpenStack and BitBucket that use the Django framework. You could attend the talk to know more about Django and its applications.

PS - The talk could also be extended by hosting the Django app on the AWS (amazon web services)


Django is a high-level Python framework which encourages rapid development, clean and pragmatic design focusing on automation which is widely supported by many deployment options. The talk would be all about a tale of building a budding crowdsourcing platform which was built using the Django framework.

Coders who are enthusiastic about web frameworks to build back-end servers.


The attendees would get close to the Django framework and know the use cases of the framework.

Along with this, they would know about a crowdsourcing platform which was built using Django.

Ethereum is one of the most popular and innovative Blockchain in the world. The demand on scaling the networks arise. Sharding is one of the way and we are working on it. This talk will introduce the recent updates of Ethereum and the basic knowledge about sharding in Ethereum.

In this talk, I will lay the landscape of current applications of intracortical brain-machine interface, including discussion on movement recovery in tetraplegics, sensory recovery in blind people, and attempts at integrating both.

Datakind Singapore has been using docker to help in reproducing environments that were used during DataDive events. A DataDive is a weekend long event where non-profit organizations work alongside data science volunteers, developers and designers to analyze data to gain insight into their programs, the communities they serve and more.     

Apart from versioning the files/scripts that we used for analysis, we also version the environments where we ran such scripts. In this session, I'll be sharing the Docker Continuous Integration (CI) pipeline/conventions we use in DataKind Singapore to promote reproducibility.     

If you have time, I encourage you to watch the talk I gave last year:     

It focused on the basics of docker and how we're planning to leverage it in an upcoming DataKind event.   


In this FOSSAsia worskhop, I'll focus and share more on our Continuous Integration (CI) setup.   

i.e. how to setup the dockerfile and related environment files in github and how to leverage for continuous integration.   


If you want to follow along during the workshop,    

I recommend creating accounts in advance in the following platforms:            

For the hands-on, I'll go through the following:     

1. Setting up dockerfile in github (for a sample jupyter notebook)     

2. How to setup for triggered docker builds     

3. How to consume docker images from   


Who is DataKind?   

DataKind is a non-profit organization which seeks to harness the power of data science in the service of humanity. Founded in New York in 2011, DataKind has since started chapters in UK, Singapore, Bangalore, San Francisco Bay Area, Washington DC and Dublin. Our DataKind Singapore chapter was founded in Aug 2014, and our goal is to connect data science volunteers with non-profit organizations to help them analyze their data for good.

Generation “Z” are digital natives who are versatile in using smartphones and the social media.  They love selfies, branded computer games and want to change the world.

Industry employment demand is usually far from this new generation’s expectations.  How to bridge this gap and get them to have skills that are future ready? How to make them purposeful Makers who is able to solve world's problems?  The Institute of Technical Education (ITE) Singapore has found a way to engage and prepare them through our new Makerspace initiative.

The Blockchain for the Internet of Things (IoT) has become a promising idea. Despite a myriad of projects on the blockchain IoT, few studies have investigated how an IoT blockchain system develops with open source technologies, open standards, and web technologies. In this presentation, Jollen will share the Flowchain case study, an open source hybrid blockchain project for the IoT. Furthermore, to provide a permissioned edge computing environment for current IoT requirements, he will adopt the Hyperledger Fabric open source, a community project under the Linux Foundation umbrella, to build a hybrid blockchain to facilitate such technical challenges.

Browsers are built on very simple principle - "one fit that suits all". Addons/Extnesions are the thing that help us to personalize the browser as per our need.We use number of addons/extensions to make most of our browser. How about being on other side of table; lets create one.Webextensions APIs are here to convert us(Javascript developers) to addon/extension developers. Javascript mixed with Webextensions APIs empower us to modify our browsers to suit as per our need. Adding to awesomeness, not only for one browser but same code that can be deployed on Firefox, Chrome, Opera with minimal or no changes. In this session,  we will be learning how to develop portable addons/extensions using javascript. One can learn how to use features of browser such as Notifications, Tab capture, HTTP request handling, Toolbar buttons via addon etc. Also I will be giving a hands-on demo of creating an addon right in the session and deploying it in the browser. By the end of session, audience will be empowered enough to command their browser to perform tasks as per their wish, may be throwing notification to drink water after every hour. By this session, I look forward to increase the circle of addons/extensions developers so as to make browsers great.

16:30 - 16:55
The work deals with learning of students on complex technical concepts in much more easier way using open source software. Mind mapping is one of the popular learning techniques employed by the academic fraternity all over the globe. This technique is utilized to improve the academic performance of the students for understanding subjects and laboratory too. This is because of the clear representation of the technical concepts in systematic way through mapping. This kind of learning helps students to correlate among the technical concepts without ambiguity. Though it seems to be simple it's impact is powerful as it works on cognition of Human beings. Instead of freehand drawing to create mind maps, open source software tools are employed. The merits of the usage of open source software are being able to create many such mind maps in short duration, edit them at any time, able to add attractive colors and patterns to create interest and gain attention of students, design in numerous ways to develop creativity and so on. Of the majority of the methods employed, this teaching - learning technique has gained prominent importance among students. The result of this work is found to be amazing among all the students for both theory subjects and practicals. There has been phenomenon change in understanding the technical concepts and analyzing them. After witnessing its strong impact at the academic results, my peer academic group started using the software. 

The workshop will proceed as follows:

  1. Introduction to Python
  2. Setting up Python environment
  3. Introduction to Google Cloud
  4. Setting up GCloud SDK
  5. Installing GCloud packages for python
  6. Writing a sample gcloud application
  7. How to run an instance (Debian VM) on gcloud
  8. Introduction to Image Processing and OCR
  9. Image Processing and OCR using Compute Engine

The current excitement around Bitcoin as "decentralised crypto money" has left us in a state where some of the fundamental ideas behind it -namely anonymous p2p economic exchange, technoactivism to re-enfranchise people from the centralised control of fiat currencies and other ideas loosely referred to as "crypto anarchism" are being fast forgotten.

Not only has bitcoin (and its contemporaries) become defacto stores of perceived economic value rather than a medium for its exchange, of recent times a large-scale shift is taking place in the (computational) power balance which determines control over its network. This shift is concurrent with efforts to de-anonymise pseudonymous identities transacting on the public ledger and legally regulate (AKA Tax) cryptocurrency transactions.

User context and their interactions with the nearby world play a vital role in creating a magnificent user experience. Instant awareness of the nearby surroundings can be an amazing way to understand the users and their behaviors. The emerging new technologies like Google's Awareness and Nearby APIs, Beacons, NFC cards and WiFi signals have opened up a sea of possibilities for developing magical user experiences.

This talk will encompass the importance of user context, Eddystone beacons, Google's Nearby and Awareness APIs; and examples of some of the experiences you can build with them. It will also cover ways to understand user behavior and customisation based on user actions eventually resulting in user retention. 

17:00 - 17:25

Today, various enterprises make sure we have no right to our own privacy through both direct and indirect means for profit.  What are the design challenges for a privacy preserving, user centric, community reputation system which enables global trade and finance?    

OAuth is a way of telling your Social Provider like Facebook. that they can share parts of your information (not everything) with other websites, without revealing your super duper secret password to these other websites. In other words, it's a way of providing permission which also includes authentication.

As Google Summer Of Project, I implemented OAuth2 Library "The League OAuth2" in modules of Drupal Social Initiative. We also released 2.x Version of these modules, which had streamlined authentication system, easily to implemented and were more secure. 

This talk will be based on why you should use protocol standards such as OAuth2 over traditional login based approach.

The first generation of microservices was primarily shaped by Netflix OSS and leveraged by numerous Spring Cloud annotations all throughout your business logic.

As organizations adopt cloud technologies, the need for codification and automation quickly becomes apparent. No longer can engineers create individual servers by shell commands or click through a GUI to provision machines. To add more complexity to the equation, many cloud vendors offer proprietary services that need to be integrated into applications. This new cloud-based world demands automation across the entire stack.

This talk discusses some patterns and open source tools for codifying machines as code, infrastructure as code, and security as code using tools like Packer, Chef, and Terraform.

MySQL is unique in many ways. It supports plugins. It supports storage engines. It is also owned by Oracle, thus birthing a branch (Percona Server) and a fork (MariaDB). You're a busy DBA having to maintain a mix of this. Or you're a CIO planning to choose one branch. How do you go about picking? Supporting multiple databases? Find out more in this talk with a special focus on MySQL 8.0 and MariaDB Server 10.3 (which comes with Oracle compatibility functions). Learn what others are doing (including popular projects like cPanel). See where people are migrating. And decide on what to use for the next 24 months!

We use radio communications systems everyday; technologies such as Wi-Fi, Bluetooth 3G, 4G and many more are an integral part of our society today. However, do we understand how they work? The Insta-QRP Radio Transceiver is a open-hardware radio transceiver kit that aims to demonstrate the concepts of radio transmission and reception.

A few years ago, a new type of currency emerged generalized as a “synthetic” currency. It is called synthetic because it is not operated by any state or even has any tangible value rather it seems to be a new asset that is trade-able resulting from an agreement between two individuals secretly and it is facilitated with the help of internet technology. Included in this synthetic currency is Bit coin (BTC) that has proved to be one of the most important one. BTC can be stated as “Digital money is simply the idea that, thanks to technology, money can now be a digital object, a unique serial number that can be directly exchanged anonymously and without accounting, just as one person would hand a dollar bill to another person, you had it, now they have it, Very simple”. There is already a lot of usage of digital money, for example when a person makes a transaction the system identifies the person and makes credit equivalent to the amount of deposit, which makes it digitally usable on ATM machines or in transfer from person to person or can be utilized to purchase goods or services. But this is not related to concept of digital currencies because a digital currency is more like a real form of currency with a characteristic of independence i.e. free from intermediaries such as central banks. Hence the whole system of digital currency is decentralized and there is no decision making involved by politicians or governments or banks. Such as Bit coins work through cryptographic algorithms to make the currency digitally usable. There are people who like the idea of currency which does not involve people in grey suits i.e. bankers and politicians who have had the system under control until now. In this talk, the focus is on the level of understanding or perception among the individuals regarding the bit coin currency in the domain of cryptocurrency.

17:45 - 18:10

In Sept. 2017, the Red Hat Product Security Team was notified of a security flaw affecting bluetooth stacks of Linux, Android, IOS and Windows operating systems. This was probably the first cross-platform security flaw of its kind. The impact was evident by the fact that the attacker did not even need to be paired to the victims device in order to exploit it. This talk briefly discusses the security flaw, the exploit mechanism and how such flaws can actually cause much more damage than what is initially evident.

I've wanted to build a small cloud at home for some time, mostly to serve as a testbed for my development projects. But also as a platform to virtualize my growing home infrastructure. So I allocated a budget of ~$1500 USD (the price of my first desktop computer) and set out to build a cloud using OpenStack. OpenStack is an open source cloud ecosystem designed to provide users with programmable open infrastructure. It  is used to power some massive private cloud deployments. But, how does it work for an individual wanting to deploy a cloud with their own resources? This talk will provide an overview of my experience building a small compute cloud from scratch, on essentially a shoestring budget; from hardware acquisition, through installation and configuration of the cloud, to my use cases for the cloud. This will serve as an introduction to OpenStack and getting started with it and will also cover the potential benefits you can get by having your own cloud at home.

A  fundamental challenge in many societies is peer learning and information sharing. We tend to group ourselves into our interests and professions and often miss out the issues and fears of the broader community.  Is it possible to get people from diverse occupations and age ranges to come together and learn from each other? We believe that such a learning and informed community will undoubtedly prefer adoption of open technologies and solutions. We will show you examples, and share some insights from Vietnam, Cambodia and Singapore, where we have some success encouraging community learning via un-conferences and small meetups. We also invite you to share your experiences with your city, school or organisations where people come together to learn from each other.

I will be talking about how we moved our legacy codebase which was in Java to Kotlin which is a more modern programming language with built-in support for various higher order functions which Java lacks.

I will be highlighting the pros and cons of the language and the difficulties we faced while doing so.

The talk is aimed at everyone who is either an android developer or someone who plans on getting into Android Development.

I will also outline how you, as a developer can contribute to the project.

Open Source Design collective ( works to raise the profile of good design in open source software, and connect developers & designers to make it happen.  We run an Open Source Design community forum, organize design tracks at well-known events like FOSDEM, FOSSASIA and OpenTechSummit, have a job board to get designers involved, provide open design resources to developers & designers, and more.

To start the track this year we want to discuss what happened in design for FLOSS since the last year design track at FOSSASIA. What is Open Source Design collective, what work has been done through out the year. What are other design projects in FLOSS you can be part of.

Target Audience:

anyone who wants to learn more about non-code contributions in open source  (particularly design and usability research) 

Desired Outcome:

For beginner designer to learn/share how to be involved in open source, for engineers to learn/share how to find designers for their projects. 

Up till MySQL 5.7 version, DDL statement execution is non-atomic which caused many issues with respect to DDL crash safeness and slave drift in replication setup. New transactional Data-dictionary implementation in the MySQL 8.0  helped in making the DDL statements atomic in MySQL 8.0.

"Now DDL is atomic  in MySQL 8.0"

An atomic DDL statement combines the data dictionary updates, storage engine operations, and binary log writes associated with a DDL operation into a single, atomic transaction. The transaction is either committed, with applicable changes persisted to the data dictionary, storage engine, and binary log, or is rolled back, even if the server halts during the operation.

With this new implementation in MySQL have eliminated possibilities for internal consistencies in the server and SE after crash. Also in a replicated environment this is especially important since the probability for slave drift caused by crashes during execution of DDL on master/slave is eliminated.

Key Take aways:


What is  atomic DDL ?

What improvement atomic DDL gets to the user ?

What helped in implementing atomic DDL ?

Supported DDL Statements.

Changes in DDL Statement Behavior.

Storage Engine Support.

For self-hosted cloud, we also provide a generic cloud-init enabled image.

CoderDojo is a movement is a grassroots organisation with individual clubs (called "Dojos") acting independently. Supporters of CoderDojo believe it is part of the solution to addressing the global shortage of programmers by exposing young people to ICT at a young age.

10:30 - 10:55

Free and open source software have empowered people to have control over their lives, which are increasingly dominated by computer technology and notably, software. A weakness in this ecosystem is that tangible Internet services are dominated by companies that operate centralized, cloud-based services. These run counter to the tenets of free and open source software despite the fact these services often use this very software.

The proper use and application of such free and open source software for Internet services is important. This comes in the form of decentralized services, themselves powered by free and open source software.

Neeraj will discuss a very specific use case of decentralized Internet services -- the idea of a decentralized key-value pair database network powered by AGPL software. The network is enabled by a crypto-economy of producers and consumers that all use this AGPL software in the form of daemons, API’s, libraries, and tools. The talk will focus on the need for decentralized services and how they are the embodiment of the spirit of free and open source software, when it comes to the use and application of such software, with a brief discussion on the world decentralized database case study.

Kirigami UI is a set of extensions to the touch friendly Qt Quick Controls framework that defines precise UI/UX patterns to allow developers to quickly develop intuitive and consistent apps that provide a great user experience.

This allows application developers to write their UI without explicitly worrying about deployment results on various form factors, such as Desktop/Tablet/Mobiles. This is the idea behind convergent code and Kirigami UI framework is one such tool in this direction.

Join me in taking a look at a few applications that are written using the Kirigami UI and how they behave on different form factor devices.

Every software professional knows the challenge of being asked to deliver in a shorter time frame, or to do more in the time available, or watched as timelines slip away through endless bugs or rework, yet there are development teams out there which eclipse their peers and somehow deliver more. What are the secrets of these “high-performing” development teams, what are the roadblocks to implementing them, and how can you take your development process from good to brilliant?

This session will provide some answers, drawn from the experiences of the team and our clients, including:

  • What is a high-performing development team?
  • What development practices do they use?
  • What should your deployment pattern look like?
  • What kinds of code management and branching patterns are most effective
  • What should you measure?

This is a non-technical session focusing on actionable best practice, which is suitable for everyone from software developers to CTOs.

Rancher is an open source project that provides a complete platform for running Docker in production. Using Rancher, organizations can run Rancher in a provider agnostic fashion, running workloads across different cloud providers and even bare metal setups. Glints, the platform for young people to discover their careers, has been running Rancher in production since 2015. In this talk, I'll be going through Rancher's primary use cases for Glints and how Rancher's flexibility has allowed us to iterate quickly.

This talk will go through two main features of MySQL with examples quite relevant to the distributed NoSQL & SQL era of applications. First part will go through the usage of MySQL JSON as both NoSQL and SQL data store at the same time with examples and use cases. The second part will concentrate on distributed transaction standard and how MySQL can be used as a resource manager in such a distributed transaction which can span across heterogeneous functional nodes and across geography.

Making WiFi Great analyses the performance limitations commonly found in WiFi networks, revealing secrets and best practise, and takes the participant through practical steps on how to optimise their network, complete with concrete examples and experience.

The Open Source and Standards team in Red Hat is using metrics more regularly to measure the health and activity levels of projects and their attendant communities. But the problem is not the data, it's figuring out what we need from the data.If you ask yourself "what makes my community healthy?" you may soon discover that the question is not so easily answered. Contribution levels, downloads, user interactions... these all sound good, but do they always answer the community health question? Depending on where a community is in its lifecycle, they may not. And, complicating the matter is that different projects have completely different end goals--more users vs. more contributors, for example. In this presentation, Brian Proffitt examines the questions that need to be asked in order to determine the answers for community health.

10:30 - 12:25

Kotlin is a new cross-platform language which supports jvm/js/llvm platforms.In this workshop, we'll implement a simple client-server app using Kotlin Native. Kotlin is a great showcase of technology that could empower back-end, front-end, mobile and desktop solutions for business.

11:00 - 11:25

We are heading into a world were the files of most users are hosted by 4 big companies. This is the case for most home users, companies but also education and research institutions. If we want to keep our sovereignty over our data, protect our privacy and prevent vendor lock-in then we need open source self hosted and federated alternatives. The internet and the web use a distributed and federated architecture. Now we have to make sure that cloud services follow the same model. 

A new challenge is the increasing blending of application hosting and storage as seen at Office 365 and Google Suite. This has the danger to lead to a very strong vendor lock-in. 

This talk will discuss the ongoing trends in this areas and possible solutions. It will also give an overview of newest Nextcloud features and the long term roadmap to provide an alternative to centralised services.

All you need to know about how and when to use Histograms in MySQL. This feature was introduced in MySQL 8.0 and is very helpful when indexes are not present in your database tables. 

Learn how a simple statistics of grouping the frequency of any values miraculously speeds up the execution of queries without indexes. 

Performing periodic backups in computer networks is indispensable. In times of Locky and other ransomware backups are often the only option left to regain access to your data. Nevertheless, for backups to be effective against these types of threats, a number of aspects have to be considered.

This presentation shows how to use the open source backup solution Bareos, to regularly create backups of your systems in a heterogeneous network.

Bareos (Backup Archiving Recovery Open Sourced) is a reliable network open source software to backup, archive and restore files from all major operating systems. The fork was founded 2010 out of the project, in order to pursue development of new capabilities and sustainable ensure it’s open source character.Today Bareos comes with a new multi-lingual and multi-tenancy web ui including restore browser, LTO hardware encryption support, bandwidth limitation, cloud storage support, a redesigned plugin interface, among other new features.

The source code is available on Github and is licensed with AGPLv3. There are ready to installrepositories for all major Linux distributions, MacOS and Windows installer packages.

Today Bareos is the only 100% open source backup solution with professional subscription and support services.

OpenStack is the most widely used open source cloud operating system these days. It provides Infrastructure as a Service for creating your own public and private cloud in house. It is easy to install and provide VMs for use cases. It contains many various services catering to different needs. These services used to run as systemctl processes. With the recent OpenStack Pike release, these services are run inside container. In this session, I will talk about one such OpenStack project called Kolla which plays an important role in this enablement. I will also talk about OpenStack installer called TripleO, How it deploys containerized overcloud, its interaction with Kolla, Puppet, and other OpenStack services and advantages of containerizing OpenStack.

This talk will take you through some tools and techniques I used to reverse engineer the keyboard controller in my Thinkpad x230 laptop.

I was driven to start this project when the laptops currently on sale just did not meet my requirements.  Even the durable Thinkpad laptops I preferred in the past are being dumbed down.  Eventually, I will need a new laptop - and with the available offerings, I just do not want anything that currently can be purchased off the shelf.

To keep the project achievable, I reduced my gripes to just the keyboard - asking the question: "Can I shoehorn an older keyboard in a modern laptop?"

Taking you through UEFI, ARCompact CPUs, Firmware Reversing, big structure dumping, SMM and custom virtual machines to answer that with "maybe."

I hope to inspire others to address their hardware gripes too - and offer some tools and confidence that they can.

The YouthMobile Initiative builds on the experience of many worldwide initiatives that introduce young people to computer science programming (learning-to-code) and problem solving (coding-to-learn). It also seeks to build on experiences targeting young women who are vastly underrepresented in this field. Finally it builds on the consideration that for millions of young people, the smartphone in their pocket is a very powerful computer, it will be their only computer, and they use it for nearly every aspect of their lives: communicating, learning, taking pictures, and playing games.

11:00 - 11:55
It's the wild wild west for cryptoledgers and their most known application, crypto currencies. Billions of dollars worth of value are literally being generated out of thin air. But the promise of smart contracts transcends the impact of the industrial revolution. What are the technologies behind this? Are they reliable? What are their capabilities and limitations? Can they realize the potential of smart contracts? How far can they take us in their current state? What does the future hold? What is Dijkstra's Revenge?

OpenStack is complex with lots of services and choices to deploy your own cloud in any fashion.

Deploying OpenStack from sources is hard. RDO is an OpenStack community distribution for RHEL/CentOS and friends.

RDO make it possible by delivering latest RPM packages with the help of different deployment tools by chasing trunk through different CI/CD with in days from upstream release.

In this talk, we will be talking about:

* A little history about RDO

* How we used to release vanilla OpenStack 2 years back.

* How we reached two days time frame on releasing RDO after upstream openstack releases through different CI/CD and proper testing.

* How Ansible and Upstream OpenStack tools (zuul, gerrit, nodepool, ARA, CentOS Infra, software factory) made it possible?

* Making OpenStack usable to work out of the box through Tripleo, Puppet, Kolla CI

* Making it easy for installers to test against latest upstream code so that they can

 Get released shortly after the services.

* How we are making OpenStack better through RDO?

* How you can also contribute in making it better?

Analyzing data to make crucial business decisions is vital for any company to survive in today's competitive market. Even more so when we consider the eCommerce industry. In every corner of the world, eCommerce companies are vying to capture the market share. As a result, companies are required to provide processes and infrastructure to allow data access to Business Intelligence and Development teams without compromising on regulatory requirements. To solve this problem, there is some commercially available software which encrypts data at rest by using key management within or outside the RDBMS. But we have been able to solve this problem innovatively by using triggers and a set of Python scripts which is free, masks data in real time, has simple to configure columns for masking and retains the usability of data after masking. We have developed a set of functions for each type of sensitive data that is used in various applications most commonly. We will also discuss pros and cons.

Presentation of VLC 3.0 and what is new in the VLC 3.0 release.

We will explore how to boost the usability of web and mobile-web apps by implementing offline-first functionalities, it's the only way to guarantee 100% always on user experience. Low signal or no connectivity should no longer be a blocker for the user, we will discuss the available solutions for caching, in-browser database, and data replication. We will also take a look at how WC help solving those issues out of the box.

12:25 - 12:35

Publicly funded software ought to be Free and Open Source Software (FOSS). While there are plenty of good reasons for this line, many decision makers in the public administration are still unaware.

Digital services offered and used by our public administrations are the critical infrastructure of the 21st century. In order to ensure our systems are trustworthy and reliable, governments and businesses must have full control over the software and the computer systems at the core of the state digital infrastructure. However, right now, this is rarely the case due to restrictive licensing models that:

  • Prevent sharing and exchanging publicly funded code. This prevents cooperation within the public administration and with businesses and hinders further development.
  • Result in formation of monopolies by hindering competition. Make administrations become dependent on a handful of companies.
  • Endanger the security of our digital infrastructure by denying access to the source code. Without code access fixing backdoors and security holes becomes extremely difficult, if not completely impossible.

We need software that fosters the sharing of best practices and solutions. We need software that guarantees transparency, government oversight and trust. We need software that helps public administrations and businesses regain full control of their critical digital infrastructure, allowing them to remain sovereign and provide their services to the citizens. We call for support of Free and Open Source Software (FOSS) in public administrations, because:

  • FOSS enables us to use, study, share and improve applications.
  • FOSS licenses provide safeguards against being locked in to services from providers that use restrictive licensees to hinder competition.
  • FOSS ensures that the source code is accessible so that security weaknesses and backdoors can be fixed.
  • Public bodies are financed through taxes. It is their mission to make sure they spend funds in the most efficient way possible. If it is public money, it should be public code as well!

In the initiative we call on decision makers, businesses and representatives to:

“Take all necessary measures and work together to implement legislation requiring that publicly financed software developed for public sector must be made publicly available under a Free and Open Source Software license.”

12:30 - 12:55

In overall success of localization timely translation and their packaging/shipping for targeted release matter the most. Plus packaged translations should be tested as well. In some cases upstream manages the workflow and in another may it be managed for downstream only. In total a sync between upstream, translation platform and build system seem missing. Which actually results in delay or poor localized interfaces. Transtats is an attempt to fill this gap. It answers some of the questions like (1) Translation status of packages at all three places (2) Translation workload estimation for coming release (3) Translation coverage of a list of packages in a set of languages for a given release. Along with this, it can automate a few steps of l10n workflow as well.Lets discuss Transtats in detail. This project is in early phase of development and any feedback would be of great help!

Rapid innovation, changing business landscapes, and new IT demands force businesses to make changes quickly.  In the eyes of many, containers are at the brink of becoming a pervasive technology in Enterprise IT to accelerate Microservices delivery.  In this presentation, you'll learn about the

           • The transformation of IT to a DevOps, Microservices, and Container based Architecture

           • What are containers and how DevOps practices can operate in a Microservices based environment

           • How Kubernetes can reduce software delivery cycle times, drive automation, and increase efficiency

           • How other organizations are using DevOps + Containers with Microservices and how to replicate their success 

Also, a demonstration of automated container based Microservices builds and pipelines, running Jenkins CI on Kubernetes, and continuous deployments of containerized Microservices with Kubernetes.

There are substantial improvements in the Optimizer in MySQL 8.0. Most noticeably, there’s added support for advanced SQL features such as common table expressions, windowing functions, and a grouping() function. DBAs will also appreciate the invisible indexes and additional hints that can be used with the query rewrite plugin. On the performance side, cost model changes will make a huge impact. JSON support is even more powerful, with the addition of adding functions requested by users.

Altruistic data scientists are always trying to make a positive impact society. Non-profits often lack the resources and know how to analyse and exploit their (or open) data. DataKind SG is non-profit organisation dedicated to bring data scientists and non-profits together to make good things happen. We are part of the global DataKind network headquartered in New York.

We will share our learning for our two DataDives and one DataCorps over the last year. The projects we did cover the gamut from healthcare to ecological conservation.

The project aims at proposing a solution to restore underwater images for Marine Archeological studies. This work was done during a research internship at CSIR-National Institute of Oceanography. We worked with datasets provided by the field work and underwater explorations in the Arabian Sea along Western Coast of India. In this project, the traditional image restoration approach is extended by incorporating underwater optical properties into the system response function. Underwater turbidity causes loss of clarity transparency, visibility and the luminosity in underwater images to study a particular scene for Marine Archeologists. In this project, we have implemented and compared different methods of underwater image enhancement and restoration which are degraded by the turbidity in water. We implemented the various image processing algorithms considering an average quality camera (i.e., Logitech C920). The algorithms implemented in a step-wise manner are preprocessing, filtering, enhancement and denoising based on a model. Images tend to get degraded as the depth and turbidity increases, the amount of light on objects decreases and light distribution becomes nonuniform. To tackle this issue, the input images are converted to YCbCr color space and Contrast Limited Adaptive Histogram Equalization (CLAHE) is performed on the Luminescence(Y) channel of the image which improves the local contrast, at the same time limiting the amplification which can over-amplify the noise too. The filtering and enhancement were done using the Bilateral Filter and then finally the enhancement was carried out using the wavelet denoising method and de-blurring. Due to the intensity variations involved in underwater sensing, denoising is carefully carried out by wavelet decompositions. This is necessary to explore different effects of restoration constraints, and especially their response to an underwater environment where the effects of scattering can be easily treated as either signal or noise.

Since our solution aided the marine archeologists in their studies, we gave more emphasis to the information extraction and the visibility of features rather than the enhancing the physical features of the underwater images.

MySQL provides various options to enhance security of server-client connections. In this talk, we will go through various such features available in MySQL. Talk will cover features like TLS connections, use of ciphers, support for CRLs, configuring user accounts to achieve better security etc.

Database is the core of many systems. If you are building an e-commerce website, government portal, health management system or just a blog, you need a database.Usually, database security system usually the last security layer between your data and hackers. Suddenly, this is also mostly underused security functionality in modern applications. You may find many books and papers about network security, firewalls, cryptography and even application security, but not database security. In the following session, I am going to introduce the audience to PostgreSQL security system. The audience will learn about authentication, authorization, roles, permissions and data encryption. We will talk about database security best practices which can help you to protect data even when your application has been compromised. The ideas from the session might be applicable to other database management systems.

TagUI is an open-source tool for automating UI interactions. Use cases include process automation, data acquisition and testing of web apps. It was built with focus on web-apps, but the focus is now expanding to desktop apps as well, using visual automation. Eventually, people will probably know it as an open-source RPA (robotic process automation) tool. It basically takes in 21 different human languages describing UI interactions and translate them into working JavaScript code to drive automation of sequences of actions (personal or business process workflows). It does not have AI / machine learning capabilities yet. Part of my job scope at AI Singapore is to integrate AI capabilities into the tool and continue releasing it with an open-source license. TagUI Features * automate Chrome, Firefox, PhantomJS * visual automation of websites and desktop * write in 20+ human languages & JavaScript * Chrome extension for recording web actions * unzip and run on macOS, Linux, Windows * R & Python integration for big data / AI * run by schedule, command line, API URL * advanced API / command calls to services

This talk will look back at four years of development of a popular (in its niche :-) ) Jabber/XMPP client for Android and explain why we need open, standardized protocols for secure and private communication but also explain the challenges that go along with it. The talk will hit the following topics.

* Why is federated (provider independent) instant messaging important?

* Can Jabber/XMPP be a solution? Is fragmentation a problem and if so how can we solve it?

* What challenges did we have to overcome in the past (Push Notifications, Battery consumption, E2E encryption)

* What challenges are left?

The classic "Western" IP bargain -- socially-sanctioned, time-limited monopolies in exchange for taking creative and technological risks -- is an age-old concept dating from 15th century Venice. Since then, the Internet was invented, changing the metric for innovation from attribution to virality. The age-old IP bargain has struggled to keep up with this transformation. This talk examines Shenzhen as a culturally isolated petri dish for innovation that exploded symbiotically with the Internet. I will share my observations on the trends and practices that are evolving in an ecosystem that is unbiased by the Western IP bargain.

13:50 - 14:09

Most of the people really like GUI, WebUI, smartphone application such as Thunderbird, Gerrit, Slack, etc. I think they are really fancy and cool. However, it sometimes requires complicated operation with a mouse, swipe and taps. Moreover, it's a bit difficult to tell how to operate to the others. To do so, we need a lot of screenshots of that application. It makes our productivity low. So, instead of that, there are a lot of CUI/CLI tools as alternatives. They are really simple but powerful and fast. In this session, audience can see the benefit of CUI/CLI tools. And, as a developer, making a fancy GUI application is really hard. We actually have a lot of options not only using GUI applications but also CUI/CLI ones. I really love CUI/CLI applications recently. Because it's simple, fast, lightweight and can be operated with only a keyboard not mouse. In this talk, I'll give some example GUI and CUI/CLI apps and talk about its pros/cons.

In this paper, we propose a communication method based on Software Defined Radio and LTE, which includes Modulation / Demodulation, Orthogonal Frequency Division Multiplexing (OFDM), eSIM chip, and International Mobile Subscriber Identity (IMSI). So that the communication mode will be able to multiplex the operation and serve multiple satellites, the construction of LTE satellite station and proprietary frequency to apply to the IoT cubic satellite group on the communication. The operation mode can be used on non/synchronous LTE satellite station, and satellite communication authentication with IMSI code for IoT cubic satellite. If the LTE signal is accessible, and authorized to talk, the data will be sent through. The LTE ground station will be the gateway, and downlink to the ground. This method proposed in this paper is applied to LTE ground station, and LTE satellite equipment (UE), with a view to construct IP network of satellite.


Implementing a public, permissioned blockchain for online digital identities.

As a teaching assistant in college, we assign students to interview on people about how much do they know about free software.From the 1100 data, we receive some interesting response, where most of the interviewee agree on the spirit of free software,however,when it comes to "actual appliance on real lives", only few of them choose to stick to free software.What makes the distance between "agree to it" and "do it" ?

In recent years, the number of open-source components used by developers to build software has seen immense growth. Millions of open-source libraries are distributed through centralized systems like Maven Central (Java), NPM (JavaScript), and GitHub (Go), and their widespread use means that bugs and vulnerabilities impact large numbers of downstream applications. In this talk, I will introduce the common security problems facing enterprises using open source code. We will also talk about how to manage the open source software risks using people, process and tools.

The Common Voice project is Mozilla's initiative to help teach machines how real people speak.

Voice is natural, voice is human. That’s why we’re fascinated with creating usable voice technology for our machines. But to create voice systems, an extremely large amount of voice data is required.

Most of the data used by large companies isn’t available to the majority of people. We think that stifles innovation. So we’ve launched Project Common Voice, a project to help make voice recognition open to everyone.

The recent enhancements to MySQL replication make operations easier, further reduce the administrative overhead, provide a much improved user experience, and enable running MySQL smoothly both at scale and/or in very tightly coupled network infrastructures such as in a clustered environment. There are enhancements across the board, such as:

- Performance improvement in the applier, resulting in increased replica throughput.

- Enhanced instrumentation and monitoring, resulting in more reliable replication observability;

- More flexible multi-source replication and filters, making it easier to deploy complex topologies;

- Extended metadata into the binary log stream, greatly improving change capture workflows.

Take the opportunity to learn, directly form the engineers responsible for the product, how the latest developments in replication will continuously enable you to grow your business on top of MySQL.

Kubernetes(k8s) is the most popular and famous container orchestration software these days. And we can use it through Kubernetes as a Services such as GKE, EKS, etc on public clouds. However, I love FOSS! So, I'd like to use it on my machine (I call this my "private" cloud) as possible :) Fortunately, there are so many k8s FOSS cluster management/deployment tools recently such as OpenStack Magnum, Mesos DC/OS, Rancher, etc.. We can use them as alternatives.

In this talk, attendees will get to know "what is Kubernetes?", "how do we deploy it?", "What's the difference between the k8s FOSS management tools?" and their pros and cons.

14:30 - 14:55

Kubernetes has won the orchestration war but now how-to developers build production ready code with Kubernetes? Standalone Kubernetes still requires a layer of management and Kubernetes alone isn’t the answer developers are looking for. 

Times are changing - Virtual Machines are too slow, too heavy weight and frankly expensive for some customers workloads. This is where containers fill the gap for flexibility, scalability, light-weight infrastructure matched with a per-second billing model, customers get exactly what they pay for. You could run a container on a VM - but this is a huge waste of “space” when you think about how much compute you actually need versus the amount of time you are running the job for. Azure Container Instances and other pods as a service platforms like or Fargate from Amazon, is the story for flexible billing, instant compute power and efficiency within the cloud. Now customers can provision as many light weight containers as they want and have fast start up times with one command. This changes the game for deploying infrastructure. Developers have an easier job of provisioning and deploying their infrastructure and only have to worry about their direct customer interactions and content, with their applications.


The safety of miners is a major problem today.Due to several critical issues like working environment and also the after effect of it is making the  miner's health and life is vulnerable.Mining activities release harmful and toxic gases in turn exposing the associated workers into the danger of survival.Miner’s health is in jeopardy mainly due to the toxic gases which are very often released in underground mines.The human senses cannot sense these gases easily.

A real time monitoring system using wireless sensor network and multiple sensors would be developed to sense, monitor and give early warning to the miner's to avoid fatalities.

This Monitoring system:

  • keeps a track on surrounding environmental parameters such as temperature, humidity and multiple toxic gases and displays it.
  • Sends an early warning, which will be helpful to all miners present inside the mine to save their life before any casualty occurs.
  • Uses Zigbee technology to establish wireless sensor network.
  • Is wireless networking standard IEEE 802.15.4, is suitable for operation in harsh environment.
  • Will contain Arduino which is an open source hardware and software, based on micro controller and several components like boards (Xbee module and Zigbee USB interfacing board), LCD (Liquid crystal display), different sensors like MQ7, MQ4, DTH-11 Sensor and other small electronic components.
