Welcome to the FOSSASIA Summit 2017 at the Science Centre Singapore.


09:10 - 09:25

Can a future of Singularity as articulated by Ray Kurtzwild and also the gloom and doom as noted by Stephen Hawkings indeed be a cataclysmic end to humanity - just as the meteoric accident that killed off dinosaurs? I will paint a picture of hope and one of collaboration. There are plenty of rules we can articulate and follow - including the 'new overlords'.


09:30 - 09:40

Artificial Intelligence and Science


09:40 - 10:05

How Singapore Government’s central information technology systems and infrastructure, drives the development and delivery of innovative public services for citizens and businesses.


10:05 - 10:35

Are you looking for ways to get involved with Open Source in the Cloud? Here's your chance. In this talk, I will briefly talk about Google Cloud Open Source products and related projects, including machine learning, systems, client side libraries and data analytics tools. I'll explain how you can get involved, contribute and share some tips for code reviews.


10:35 - 10:50
10:50 - 11:15

AI Assistants are able to augment the human intellect, to perform task and offer services, to have capabilities beyond the ordinary power of humans. With open AI Assistants a community can create such tools for their own need. We show that the creation of such tools can be as easy as writing a wiki article. With the proper Cognitive Assistant Technology we will be able to augment human intellect in the same way as it is possible to document the world knowledge with the wikipedia.


11:20 - 11:40

Natural Language Processing (NLP) is the task of the computationally understanding and production of human languages, often using a mix of hand-crafted rules and machine learning techniques. The recent hype in artificial intelligence and deep learning has brought a tsunami of media coverage, governmental interest and public enthusiast. And NLP rode the wave and pushed the computational processing of language to the current frontier. In this talk, we will go through the various NLP open source available and share my experience being a contributor to Natural Language Tool Kit (NLTK) and Moses machine translation suite.


11:45 - 12:05

In the recent years, EEG brain-computer interfaces are becoming popular and more accessible to consumers. Applications range from controlling computers, machines, biofeedback, to quantified self tracking. At first sight, the current generation of commercial devices seem to be decent in their functionality, and various use cases are suggested. However, neurophysiological signal quality, as well as limitations of software and hardware hackability are among the greatest issues and hurdles towards advancement in user experience. This is why we started to work on Brain-Duino, an open-source brainwave amplifier shield for the Arduino and other microcontrollers.

Brain-Duino is a high quality, low noise and affordable EEG / BCI for hackers, makers, researchers, artists and other enthusiasts. This talk will be about how the Brain-Duino project started, where it is now and where it is going. We will briefly explain how EEG brain-computer interfaces work, and also why this topic is relevant, together with the current advances in artificial intelligence and hardware.

During the FOSSASIA you will have the chance to try out the Brain-Duino and visualize your brainwaves.

13:30 - 13:55

As society and technology become more deeply intertwined, society is taking interest in -- and influencing -- nuanced technological issues, ranging from net neutrality, to the selection of emojis, to the enforcement of open source licenses. The FOSS community takes for granted the values of open source, but the benefits can be difficult to explain to those who are not empowered to utilize the source. This talk examines some of the cultural and technological barriers that have stymied inclusiveness, using gender imbalance as a case study. Finally, we propose a solution which we call "Love to Code", which attempts to address the issue of inclusiveness in technology.


14:00 - 14:20

Andrey will talk about Microsofts Open Source strategy. He will put a particular focus on scaling up open source workloads on Microsoft Azure cloud platform.


14:25 - 14:50
The privacy and the personal data on the internet are under attack by hackers and international espionage programs. If we want to use the internet as a free and democratic medium again then we have to fix the internet to provide the security and privacy that people deserve. The Nextcloud community is build an open source and fully federated and distributed network for files and communication. Everyone can run an Nextcloud server at home or somewhere on the internet and collaborate and share with everyone else. Nextcloud can be used to provide file access, syncing, sharing, calendar, contacts, video calling, music and video streaming in a distributed way.This talk will cover the current problems with surveillance and espionage and strategies on how to fix this problem. It will also discuss the current and upcoming federation features of Nextcloud and how to become part of the community.'

09:30 - 17:10

Experimenting with self-built equipmentThe "open science" movement stimulated people to understand and get closer to scientific questions that can affect their life or the environment surrounding them. This triggered the need of cheap but sophisticated equipment for everybody. The "Rock your Rainbow" project builds an open source spectrophotometer that is affordable and easy to reproduce.With this tool everybody can approach spectrophotometry:It is possible to understand what a spectrum is, which kind of light lightbulbs do emit, and how it can interact with our circadian cycle.Another interesting field is plant pigment analysis. With easy to reproduce protocols it is possible to extract pigments from leaves, fruit or vegetables, isolate them and analyze them with the self-built device.


10:00 - 10:25

Clonezilla is a free, open source partition and disk imaging/cloning program similar to Acronis True Image®. It saves and restores only used blocks in hard drive. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (Server Edition). It could be used to Image or clone GNU/Linux, MS windows, Mac OS, FreeBSD, NetBSD, OpenBSD, and Minix. In this talk we will speak about how to deal with backup with Clonezilla.


10:00 - 10:50

A lot of pros and cons are regularly dicussed when it comes to Open Source usage in business IT. There are a lot of reasons why Open Source is ideal for business critical system, but there are also a lot of uncertainties and doubts by people who are not really involved with Open Source communities. This is in particular a topic for PostgeSQL, which is the most important Open Source solution for businesses. This presentation evaluates those pros and cons and shows how to get the most out of PostgreSQL's Open Source nature for enterprise IT.


10:05 - 10:35

A lot has happened in TensorFlow since its open-source release a year ago.  TensorFlow is an open source system for machine intelligence. It's Google's second-generation deep learning system, flexible enough for research yet performant enough for production. In this talk we provide an overview of what TensorFlow is and how it works, a summary of the new developments in the library including high-speed compilation, better ecosystem support, and easier to use high-level libraries.  We also discuss how the open source community has shaped its development and success.


10:30 - 10:55

At FOSSAsia 2015 I gave a short talk on using Puppet and Ansible to manage the configuration of desktops. In the past two years we've gained a lot more insight into the complexities of managing a fleet of machines that aren't always powered on.


10:40 - 11:10

Learn how we are bringing Android to Chrome OS devices to let users do more. This talk will cover the growing diversity of Chrome OS hardware and best practices for Android Apps on Chromebooks.


10:55 - 11:45

In Distributed System, such as Centralized Retail System like Hypermarket, there are 2 approaches for data collection and integration. Use Webservices or use Distributed Databases. By enabling Distributed Databases, and maintained it as if single integrated system, we can achieve simplicity, no context producer and subscriber anymore. this saves a lot of effort, time and resources of course. There are no worry about data synchronization, no need to maintain data Integrity with much effort. In this talk, we will cover about why and how BDR (Bidirectional Replications) implemted in high performance transaction system (which we developed, i.e POS Retail System). Why that matter and how this can be a great lesson for any other implementation.


11:00 - 11:25

We would talk about two major open source initiatives - Google Summer of Code and Outreachy.

Urvika would share her experience with "Outreachy"- Outreachy is a similar program like GSoC but it helps people from under-represented groups such as females and LGBTQ, to get involved in open source software. She would like to share her journey of getting into Outreachy in the hopes of inspiring budding female developers like her.

She would talk about how  being on Outreachy team changed her persepective from “how to code" to that of “how to contribute".

Pranav would be sharing his working and learning experience during Google Summer of Code’16 with Debian.

Both Urvika and Pranav worked on the same project - Lumicall. They would talk about “Lumicall” which is a free and convenient app for encrypted phone calls from Android. It uses the SIP protocol to interoperate with other apps and corporate telephone systems. We would be explaining the work we did using Android and Java to add new features into the existing application and how to pace the learning curve.

Urvika would also give a brief about a few subjects that she worked on using Android/Java

  1. Explaining what “WhiteLabelling” is and how can we implement it in Android

  2. Working with productFlavors, Preferences, AudioManager, RingtoneManager, Date , SimpleDateFormat, Calendar classes in Android.

  3. Pub/Sub Support

Pranav would explain about adding PUBLISH Support to Lumicall and developing a library for adding quick enroll option to Android Applications.


Introduce linux-sunxi community. This is community behind linux kernel and u-boot contributions.I'll talk about current status on contributions and which SOCs are supported on mainline.


11:15 - 11:40
There are many architectures starting with MV* prefix. I've got experience creating many apps with all of them and now I prefer to use MVVM. This talk is about why and how I solve many common problems of android developers using this approach. Model–view–viewmodel (MVVM) is a software architectural pattern. MVVM facilitates a separation of development of the graphical user interface – be it via a markup language or GUI code – from development of the business logic or back-end logic (the data model).

12:30 - 12:55

Debian is the Linux distribution that is composed entirely of free and open-source software and it is by far the largest Linux distribution available. The development is carried out over the Internet by a team of volunteers guided by three foundational documents: the Debian Social Contract, the Debian Constitution, and the Debian Free Software Guidelines, documents that in themselves have had a lasting influence on the free software world.With this presentation the phenomenon of the Debian project is explained, from its beginning to the current time, both on the technical side as on the organisational side. Debian has a lot more to offer than one can see on first glance, so it also shows why users should care and which advantages can be received from using Debian.Being a Debian developer for more than 20 years, the presenter will take the audience back in time and show how Debian got going and how it developed to become what it is nowadays.


12:35 - 13:00

LearnBot is a fully open source robot that runs on an ODROID ARM hardware. The outside is made of fully 3D printed pieces, which makes it very easy for anyone to make their own version at home. It runs GNU/Linux along with the RoboComp Framework and can be easily programmed through python components. It is meant for educational purposes, although it can be used for any other research projects. In terms of sensors it comes with a camera and ultrasounds, while regarding actuators it has motors to move around. However, due to its simple design, it is easy to add new peripherals as required.

12:40 - 13:05

In the BIOS time, the firmware was usually obscure and the OS developers had to deal with it by experience. Fortunately, nowadays most of the firmware/hardware vendors share the code from the open source project, edk2, in their own UEFI implementations, so it's much easier to understand the how the firmware works, especially the hardware-independent software stack. What's even better is that edk2 contains a sub-project, OVMF, to provide the firmware for QEMU, the virtual machine, we don't need a bare metal to implement features or debug hardware independent issues anymore. No more expensive flash programmer, just copy the file to update the firmware immediately. This talk will present how to develop and debug OVMF with openSUSE and introduce the new UEFI features in openSUSE Leap 42.2.


12:40 - 14:15

Lightning and Ignite Talks. Please check out the latest updates about lightning talks on the wiki: https://github.com/fossasia/2017.fossasia.org/wiki/Lightning-Talks 


13:00 - 13:25

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.


There's a lot of magic in Python -- metaclasses, asyncio, decorators -- you name it! In this talk I'd be covering a short introduction to these and also how and when to use them. I'd cover (a) metaclasses in Python 2 and 3, differences and dynamic behaviours that can be leveraged; (b) decorators; and (c) Mocking and Patching to dynamically control the way the code behaves.


What if all open source software can be treated as a dataset? In this session we will discuss what can be derived form such a dataset using modern machine learning tools such as DeepLearning, clustering, etc.


13:00 - 13:50

Unconventional query optimization in PostgreSQL, or how to teach an elephant to dance rock'n'roll.Query performance is usually tuned by simply adding indexes and rewriting the query minimally, while the basic idea of the query stays the same. For many query, this is not the best way to optimize them: you need to rethink and rewrite them completely. To do this, you need to know how optimizer and executor work, and keep that in mind while composing your queries. In this talk, I will present an overview of a few less known and rarely used techniques such as:* using and implementing loose index scan for different scenarios;* using IOS in situation where it isn't applicable directly;* replacing IN (long list of values) with JOIN VALUES ();* moving a limit or offset clause inside joins;* and other tricks with row types and arrays of row types.Using these techniques and some other ideas, we will learn how to optimize a 'friends feed/subscription news' query, which is a typical task in many projects. We will diretcly compare performance of four different approaches: direct approach (simplest query), optimized direct approach (more complicated version of it), pl/pgsql with different algorithms, and implementation of this pl/plsql code in plain sql. I will show how this approach can convert almost any read-only non-dynamic (no EXECUTE statements and no exceptions) pl/pgsql code to a plain sql query.


13:00 - 13:55

Working from home (or a cafe)? Working with geographically distributed teams? This is the new normal.Tools come and go, yet you'll always be thinking about the base - collaboration, interaction, decision making, conflict resolution, and most importantly communication. For people with an open source software development background, much of this might come naturally; mixed mode environments will require some tweaking.Having never worked in an office my entire career (consulting, MySQL, Sun Microsystems, MariaDB Corporation, Percona), here are some lessons that I've managed to learn.


13:00 - 14:25

As a tradition of MySQL Community meetup, we always have a platform where our community will be able to discuss everything about MySQL with our developers.


13:05 - 13:30

Scientific research is producing amazing results at high rate. However it is incredibly difficult for non-experts to understand such studies and their implications. The open source technology movement simplifies those concepts and allows the understanding of these works. This enables citizen to answer scientific questions affecting directly their lives. The "Rock your Rainbow" project aims to disassemble already existing open source spectrometers, and re-design the modules to be flexible and compatible with custom built devices. With this tool it is possible to approach spectrometry: simple examples are the analysis of light bulbs emission spectra and its influence on our psycophysical health, or the classification of plant pigments.


13:10 - 13:35

Coccinelle is a program matching and transformation tool which provides the language SmPL (Semantic Patch Language) for specifying desired matches and transformations in C code. It has been extensively used for finding bugs and performing source code evolutions in the Linux kernel. Coccinelle is designed around a language for expressing matching and transformation rules in terms of fragments of C code. Coccinelle has been used in the development of almost 4000 patches found in the Linux kernel. More than 40 Coccinelle scripts are distributed with the Linux kernel source code.The talk will highlight the capabilities and limitations of Coccinelle along with introducing various basic features of the SmPL.


13:30 - 13:55

This talk is about my work done during the GSoC coding period (May 23 – Aug 15). This project is an extension of an existing project named cyvlfeat.Brief introduction: We intend for this to be a light wrapper around the VLFeat toolbox. cyvlfeat will provide a mixture of pure Python and Cython code that looks to replicate the existing MATLAB toolbox. The role of Cython in this regard is to re-implement MATLAB mexfiles.The VLFeat open source library implements popular computer vision algorithms specializing in image understanding as well as local features extraction and matching. Algorithms include Fisher Vector encodings, VLAD, SIFT, MSER, k-means, hierarchical k-means, agglomerative information bottleneck, SLIC superpixels, quickshift superpixels, large scale SVM training, and many others. It is written in C for efficiency and compatibility, with interfaces in MATLAB for ease of use. The corresponding documentation is detailed throughout both parts. It supports Windows, Mac OS X, and Linux. The latest version of VLFeat is 0.9.20.Blog: https://gsoc2016.wordpress.com/


The Microsoft Cognitive Toolkit trains and evaluates deep learning algorithms, scaling efficiently in a range of environments—from a CPU, to GPUs, to multiple machines—while maintaining accuracy.In this talk, we'll discuss the basics of the toolkit, common use-cases, and go through a quick demo.Landing Page: microsoft.com/en-us/research/product/cognitive-toolkitSource Code: github.com/microsoft/cntk

In this workshop Frank will explain how to install and setup an Nextcloud server. Basic knowledge of Linux and webservers is recommended. Nextcloud can be installed on a small Raspberry Pi like device or on a bigger Linux system. Another topic of this workshop will be how to start collaborating with other users using the Nextcloud federation feature


13:35 - 14:00

Getting a LED to blink is easy, making a strip of 60 LED produce a pattern that is not an annoying is hard. Lets have a look at the trials and tribulations and the patterns I came across when designing lights for my use at home. There will be blinking in all colors


13:40 - 14:05

This presentation introduces the FreeBSD operating system and the community that produces it.FreeBSD is an advanced computer operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.


14:00 - 14:25

We provide updates on our OSS project, Legalese.com, which is developing a programming language to allow programmers (and eventually robots/IoT devices) to draft simple legal agreements using a domain-specific-language.


Go (often referred to as golang) is an open source programming language created at Google. Unlike Python which is an interpreted language, Go is compiled. A few projects have moved from using Python to Go lang lately. This talk summarizes observations made when a Python programmer learns Go.


14:00 - 14:50

If we look back and see the changes that have happened in last few years, we will realize that how things have changed very rapidly. A decade back, most of the organizations either would have their in-house database servers running on certain hardware and storage configuration. Over the period, when the servers become obsolete, then server/storage migration would itself become separate project and the procurement process for new hardware in any organization is usually time consuming process. In last two years, there has been rise in adoption of Cloud that tries to address this and many other issues. Now you do not have to worry about the underlying hardware and storage, once you know CPU, RAM and storage requirement, you can customize the server and build your own server in cloud. Also, migrating Postgres cluster to cloud is a viable option for safety (no data loss, including if rollback), minimal downtime (switchover and rollback), minimal effort for the team.Considering one of the above reasons for moving to cloud, one of our client’s in FinTech space decided to move their PostgreSQL instance to AWS RDS since RDS offered some of the following benefits like:• Automated failover of primary in case of failure • Automated creation of replicas• Automated updates• A purely declarative setup, via Cloud formationHere I will talk about how technical aspects of moving PostgreSQL server to AWS RDS.• How to configure, tune the parameters in config file while moving onto RDS. • How you can select the storage depending upon growth estimate and IOPS requirement• How you can configure HA setup in RDS.• How you can distribute your reporting workload.• How to monitor Postgres instance and alert configuration


14:00 - 14:55

AI Assistant Development for everyone! We do a colaborative creation of Susi Skills which is as easy as writing a wikipedia article. You don’t need to be a programmer to create an artificial intelligence which provides knowledge and IoT steering abilities.

  • What our software does and how it looks like.
  • The FOSS software stack we uses to build the planting room control system: Python, Django, PostgreSQL etc
  • Some challenge we faced (network issue, database issue) in our special condition, and how we overcame it.

14:10 - 15:05

Speaker will go into how to develop an Linux Industrial I/O subsystem driver for an entirely new sensor, and how userspace HALs can process data with reduce system I/O than a pure "userspace driver". Some of the things that will be covered is iio channel consumers + definition, SW + HW triggers, and ring buffer interface. There will be some in-depth overview of the development API to implement a new driver, or add functionality to an existing iio driver. Also will demo of several sensors using the various functionality of iio, including but not limited to hrtimer sw triggers, and buffered data to userspace HALs.


14:20 - 14:45

Git became really successful in the Open Source world and, more recently, in the corporate world as well. However, Git is not suited for large files by design which is a major obstacle for many adopters. GitLFS is an extension to Git which addresses this problem. In this talk I will explain how GitLFS works and how Autodesk uses it at scale for 4000+ engineers and 1000+ repositories. You will also learn how to use it properly and how to avoid the most common pitfalls. If you have worked with Git before then this talk will prepare you to handle large files without trouble in Git!


14:30 - 14:55

This presentation shows why the software created by OSS communities is so important for business users. It gives some motivations for the immense growth in enterprise space OSS experienced in recent years. With OSS not only fulfilling the technical requirements, but also the operations requirements it quickly became a strategical choice for a lot of companies, be it for internal IT or as the basis of their own products


This talk invites anyone who is interested in the Wikimedia's vision and in learning ways to get involved in our technical community. This talk would particularly be useful for university students, underrepresented minorities such as women in open source who are seeking to contribute to a beginner-friendly and diversity-embracing open source community. The focus would be to lay deeper emphasis on different areas through which one could contribute in our projects, such as design, documentation, research, translation, etc. More here: https://www.mediawiki.org/wiki/How_to_contribute.

We’ll talk about different outreach programs (such as GSOC, Outreachy) that we run every year and few projects (such as Community Wishlist Survey https://meta.wikimedia.org/wiki/2016_Community_Wishlist_Survey) that we promote through these programs. Some of these venues could be a good starting point for contributors to follow and get involved.


14:30 - 15:25

Python programming language has the potential to change a dull teaching learning process in to more stimulating active learning. Equations in physics and maths always look dull and boring. With the power of python one can see the beauty behind those equations and can find real world connections. With the effective use of python programs a teacher can actively engage the students and help them visualize the concepts and have better understanding.In this presentation I will share my teaching and learning experiments with Python in Science and Maths with live demo of some experiments .Join me to enjoy the memorizing patterns and mash-ups with Light, Sound, Physics and Python!

After I came home from a recent trip that happened to occur during the middle of a heat wave. I arrived to find my apartment quite too hot, it was at least 45C inside. Needless to say it wasn’t the most comfortable way to come home after 15 days out of town, I decided it was time for me to do something aboutit to address this so I didn't come home to that unpleasant surprise again.In most houses this problem is avoided by having a thermostat which controls the air conditioning. However, the problem for me was that my apartment didn'thave a thermostat for the air conditioning. So I decided to build one using open source software. This talk will cover a how I went about solving my problem using existing software and protocols like home-assistant, MQTT, and also some new software that was created for this. It'll also go over how using software and home automation I was able to not only solve my heating issue but also make cooling my apartment smarter.


14:50 - 15:15

Since it was created in 2005 by Linus Torvalds, Git has become the new standard in source code and version control. With tools like GitLab and GitHub, it opened up a new era of collaborative development. Through some of its features, let's see how it can have a great impact on software quality and agility.


15:00 - 15:25

A lot of scientific equipment produces experimental data in proprietary data formats. We think everybody should have the possibility to analyse data from scientific experiments hence the data formats need to be open source'd. OpenChrom is a processing/analysis software that contains data import routines for virtually all Gas Chromatography / Mass Spectrometry (GC/MS) systems available and in-use. GC/MS is today one of the most widely used chemical analysis techniques in the whole world.


The most popular ecosystem for Machine Learning and Data Science is the Free and Open Source Statistical Language  R. Over the past 20 years R has grown from a specialist tool for a handful of statisticians to an estimated 4 million users. This talk will introduce the R ecosystem for Machine Leaning. We will learn how Decision Trees are built through the accessible Rattle graphical user interface and showcase some of today’s developments in Big Data deploying Artificial Intelligence and Machine Learning technologies based on open source software.


15:00 - 15:55
15:05 - 15:30

Continuous Integration (CI) is crucial in modern software development. Jenkins is an open source software for this purpose. A lot of teams involve Mr. Jenkins and hope for a better quality software. But do they know that they are killing Mr. Jenkins? My talk will answer this question and introduce 3 levels of good practices to maintain a healthy, strong and long living Mr. Jenkins.

The OpenStack Community's CI System operates at a tremendous scale, with on average roughly 12 thousand test jobs launched every day. It's exciting to see testing happen at such a large scale. However there is an issue, it is too difficult for humans to deal with all the data being generated or analyze all the results from the testing. To deal with this the OpenStack community has developed and deployed several tools to help deal with the torrent of data. Using and building off these tools have been invaluable especially as the OpenStack project continues to grow. This talk will explain the basics of OpenStack's CI infra and cover the approach and tooling used by the OpenStack community to interact with the large amount of test result. It will explain the techniques used and the benefits derived from having both open test result data and performing analysis on that data to understand the project.

The Moore's law has almost come to an end and not much performance up gradation can be achieved just by upgrading hardware generations. The methods of frequency scaling and core multiplication have reached their maximum limits of exploitation and cannot be explored further. This gives rise to the need for heterogeneous computing.Heterogeneous computing refers to systems that use more than one kind of processor or cores. These systems gain performance or energy efficiency not just by adding the same type of processors, but by adding dissimilar co-processors, usually incorporating specialized processing capabilities to handle particular tasks.There are a number of heterogeneous devices that are readily available off the shelf, some of them as commercially available system on chips (SoCs) and can be easily accessible to the average embedded software programmer. These heterogeneous devices incorporate hardware accelerators, such as GPUs and FPGAs. The advantages of having multiple types of hardware accelerators within a system on chip are many, such as high-performance gains and specificity of tasks performed. One of the major issues is the exotic programming model that each hardware accelerator brings along with it. FPGAs bring along the requirement to write accelerators using hardware description language (HDL) at a very low level of abstraction (register transfer level) which has a really steep learning curve, extremely long compilation/place and route timings and are relatively difficult to debug. GPUs have their own programming languages and until a few years ago GPUs were used predominantly for graphics processing as the name suggests. However off late, with computing problems of large sizes and datasets, a lot of computations are being off-loaded to the GPU due to its benefit in parallel execution. Even with a great number of devices available, the difference in programming models makes it difficult to truly use all these devices in unison. Even with these multitudes of methods available for hardware acceleration, it is still not possible for software developers to adopt and use these devices as part of their daily routine for hardware acceleration. In order to achieve the full potential of hardware acceleration, multiple heterogeneous devices within the same SoC must be programmable using a single programming model and also the programming model must be portable across devices without loss of functionality. The aim of this talk is to throw light on the OpenCL(Open Computing Language API) and its potential for being the one single language that can be used to program multiple devices.

We present a novel approach to intelligent computer assisted language learning (iCALL) systems, using deep syntactic parsers and semantic based machine translation in the diagnosing and providing explicit feedback on users’ language errors, using Mandarin Chinese (L2) as a case study. In this presentation we describe the proposed approach and current progress of a recently funded two year project. During this project, we are developing a proof of concept system showing how semantic based machine translation can, in conjunction with robust computational grammars, be used to interact with students, better understand their language errors, and help students correct their grammar through a series of useful feedback messages and guided language drills.Ultimately, we aim to prove the viability of a new integrated rule-based MT approach to disambiguate students’ intended meaning in computer-assisted language teaching. This is a necessary step to provide accurate coaching on how to correct ungrammatical input, and it will allow us to overcome the current bottleneck in Computer Assisted Language Learning (CALL) – an exponential burst of ambiguity caused by ambiguous lexical items.

The Prosthetic arm project is about building prosthetic arms that are functional, can be controlled by the mind directly or indirectly, and that can provide a tactile feeling by sending signals back to the brain. The World Health Organization estimates that there are 40 million amputees throughout the developing world, but only about 5% of them have access to any form of prosthetic devices or assistance. The average prosthetic arm can cost between 3000 and 30000 dollars and many of these devices are not functional and are purely cosmetic. Thus I am trying to develop low cost prosthetic devices that are effective and are low in cost.

In recent years, applicable area of PostgreSQL has quickly extended into the enterprise sector thanks to continuing effort of the community to improve performance and functionality. As a result, there is an emerging demand to use PostgreSQL in more security-critical circumstances.In this presentation, I will talk about the following two topics. * Considerations for securing a database system. * Current status of database audit on PostgreSQLI am working for the open source software center (OSS center) of NTT which is the largest telecommunications company group in Japan. We have encouraged many of our customers to migrate a lot of database systems to PostgreSQL so far and this contributed much to cost reduction.Some projects need to conform to security standards, for example PCI DSS (Payment Card Industry Data Security Standard). It is one of the most prevailing security standard in the world. However it is not easy to build and operate a PostgreSQL-based system conformant to these security standards. I'd like to describe some aspects required for secure database systems in general, such as encryption, key management, identity management and auditing.Then I explain considerable points for building a secure database system using PostgreSQL, and show the remaining challenges for secure database systems using PostgreSQL.Finally, I introduce a forked version of pgaudit that we are maintaining, then explain how to use it. pgaudit is developed by 2ndquadrant and Crunchy Data, especially by David Steel with a great contribution. However, it does not meet our customer's requirements. For example, It cannot output the audit log and server log separately, it cannot audit Superuser fully, etc. So we forked it and added some changes.

The project deals with developing various mobile applications (Apps) using free and open-source web application for hearing impaired children. The work has been done in association with a Non-Governmental Organization (NGO) called SAHI, Society to Aid the Hearing Impaired which is part of Apollo Hospitals, Hyderabad. SAHI supports the hearing impaired kids for Cochlear implant surgery so that the kids audibility increases. After the surgery audio therapy is given to kids for better understanding of the surrounding world. By using free and open source web applications, MIT App Inventor, various mobile Apps have been developed for the better learning of the kids. The learning of the impaired kids have been cleared explained by the special teachers to the developers. This made to develop Apps more clearly, concisely and perfectly. Different Apps were done keeping in the view of international standard of teaching to special kids who are hearing impaired. The Apps developed covered variety of topics such as Early Vocabulary,Vehicle and Voice Sounds, Syllable Length Word (in English and local languages - Hindi and Telugu), Discriminate Consonant, Same Length Words (in English and local languages - Hindi and Telugu), Leaning by Manner, Learning of Colors, Learning various Poems (in English and local languages - Hindi and Telugu) and explaining short Stories(in English and local languages - Hindi and Telugu). The Apps have been done in both English and native languages too keeping in view of the therapy requested by the kid's parents. Tests are also included in the Apps to know the level of learning. During initial stages, suggestions were given by audiologists, special teachers and counselors. After continuous and rigorous reviews and feedbacks, the apps developed had become satisfactory to all the special trainers and was ready to use. They were given to the challenged kids for testing as a part of their learning. The results found by the teachers were astounding. Children are showing more interest to learn on mobile rather than book. The duration of attention towards learning of the kid has drastically improved. Teachers training the special kids are very happy with this m-learning (Mobile learning). Parents too found it to be amazing as their kids show more interest towards learning through mobile. Also, now they are very much comfortable to train the kids at their homes by using these Apps. The parents are very excited to get all these learning Apps shared to their mobiles. It is a great feeling of satisfaction to see kids interested to learn and the parents with bright smile on their face. This all happened by developing learning Apps of open-source software. Over all it's an awesome experience !!

Since the last FOSSASIA, the Deep Learning Workshop repo (on mdda's GitHub) has been extended substantially. Depending on the time allotted, we'll be able to tackle 1 or 2 'cutting edge' topics in Deep Learning. Participants will be able to install the working examples on their own machines, and tweak and extend them for themselves. Like last year, the Virtual Box Appliances will be distributed on USB drives : The set-up has been proven to work well. Since this is hands-on, some familiarity with installing, running and playing with software will be assumed. Depending on demand, I can also do a quick intro about Deep Learning itself, though that would be pretty well-trodden ground that people who are interested would have seen several times before.

*  Participants should bring their laptop AND have Oracle's VirtualBox already installed and working.

   *  VirtualBox is cross-platform, and open source, and enables us to distribute a full, working deep learning VM to all the participants (via USB stick).   *  At minimum, your laptop should have 2Gb of RAM and 8Gb of HD available.  No platform preference.

This talk introduces the Classical Language Toolkit (CLTK), a project bringing natural language processing to ancient languages. The talk focuses on two things, namely the CLTK core software and CLTK Archive, an interactive reading environment.The CLTK core is a Python library that offers natural language processing support for Classical languages (namely, those of ancient Eurasia, from earliest civilizations through the beginning of the modern era). It can be seen as an extension of NLTK, but with special consideration for the unique needs of historical languages. It provides basic functions for many languages (e.g., n-grams, word frequencies, word tokenization) and wider support for several languages (Greek and Latin) that includes text normalization, sentence tokenizer, POS tagging, and named entity recognition (NER). We plan to extend to other languages, as well.The CLTK Archive is a website I worked on during my GSoC project. It's a web app front-end to the CLTK core and also provides a modern reading environment for interacting with ancient texts. The Archive aims to provide an aesthetically-pleasing yet utilitarian environment that facilitates reading, note taking, and learning. It presents Classical texts in an easy-to-read layout with metadata like translation, commentary, and word definitions. The site is backed up by a Flask based REST API that provides access to text corpora and other functions of the core CLTK package. I will also be giving a short demos of the capabilities of the Python library and CLTK Archive website (available soon as an alpha release).

CoderDojo is a worldwide movement of free, volunteer-led, community-based programming clubs for young people that started from late 2011. And I started CoderDojo in Japan with my friends in OpenSource Cafe in early 2012. It was a very small start and to be honest I wasn't sure if it will grow and scale; however, the fact is that there are now 70+ communities (dojos) in Japan, 1150+ dojos in the world. This means, in Japan, that EVERY week kids can talk and learn about programming face-to-face with people in opensource communities, regardless of where they live (not everywhere for now, but almost).According to the statistics of CoderDojo, currently in Asia, this big growth only happens in Japan. But I think this kind of opensource community will be a great fit for other countries in Asia. So in this talk, as a co-founder and representative director of CoderDojo Japan, I would like to share the knowledges and experiences on how we evolve, what problems we met, and why I'm so encouraged to share them in Asia.# ReferencesKids are coding it for themselves, Nikkei Asian Reviewhttps://www.facebook.com/note.php?note_id=321408997945053&id=204862942932993DojoCon Japan - The 1st Conference for CoderDojo communities in Japanhttp://dojocon.coderdojo.jp/

Writing shell scripts in Bash (or Python) tends to be error-prone and the code does not scale well. Recently thanks to various libraries like Haskell Shelly and Turtle it has become easy to do shell programming in Haskell, which allows mixing expressiveness, type safely, and the power of the Haskell library ecosystem. In this workshop we will see through a tutorial of examples how to liberate ourselves from Bash and produce safe, scalable, and maintainable shell scripts in Haskell. Having learnt this one does not want to go back.

Please install recent ghc (I suggest version 7.10.3 or 8.0.2) and cabal-install on your machine if you want to follow along in the workshop: see https://www.haskell.org/platform/ or https://www.haskell.org/downloads. The Haskell Stack tool (https://haskell-lang.org/get-started) may also be helpful.

Docker containers have transformed how new software is developed, with hundreds of millions of containers supporting applications in production today. However, every container needs a Linux host on which to run. This talk will provide a short history and landscape review of Linux microdistributions available today, before diving into the considerations for building and using such distributions.We’ll include the architectural decision points involved with building and choosing a container-focused Linux distribution, and conclude with demos and practical use cases for developers, DevOps, and operations teams who are investigating and using containers today.


10:45 - 12:10

Running database operations in containers is a slightly different proposition than running other services. MySQL, being designed - as the majority of services - for running in a dedicated host, needs some adjusting to fit in a container. Thanks to its configurability, we can deploy MySQL containers to fit our purposes, with just the right amount of customization. However, customizing in Docker is done differently, and we will see it in detail. This tutorial will cover :* Operations from scratch, starting with running a single container;* Steps and pitfalls of customising containers;* Data management for safety and performance;* Making several containers work together in replication;* Using containers as software transporters: mixing MySQL versions and operating systems.Attendees to this tutorial will learn the basics of using MySQL containers stand-alone and in replication.

Android isn’t about phones anymore, and we already know that. Wear, Glasses and VR covered, the next big thing in android is going to be in-car entertainment. In 2016 we have already seen car manufacturers like Hyundai, KIA and Toyota equipping their urban vehicles with Android Auto capable dashboards.Right now we can make Audio and Messaging apps that can pair with Android Auto, and in the near future we will have more access to the vehicle’s CAN bus interface. It’ the time to start adding Auto support to your apps


11:10 - 11:30

Managing server will monitoring all things; disk, network, i/o, CPU, RAM, log, etc. Monitoring that all things will be easy if the number of server is small. We just take manual action, login to the server and watch the status. But, how to do monitoring if the number of server will increasing; dozens, hundreds? We need tools.ELK Stack specially can be use for monitoring log. Centralized log. Centralized logging can be very useful when attempting to identify problems with our servers or applications, as it allows us to search through all of our logs in a single place. It is also useful because it allows us to identify issues that span multiple servers by correlating their logs during a specific time frame.In this workshop, we will go over the installation of ELK (Elasticsearch, Logstash, Kibana) Stack. We will also show how to configure it to gather and visualize the syslogs of systems in a centralized location, using Filebeat. Logstash is an open source tool for collecting, parsing, and storing logs for future use. Kibana is a web interface that can be used to search and view the logs that Logstash has indexed. Both of these tools are based on Elasticsearch, which is used for storing logs.It is possible to use Logstash to gather logs of all types, but we will limit the scope of this tutorial to syslog gathering.The goal of the workshop is to set up Logstash to gather syslogs of multiple servers, and set up Kibana to visualize the gathered logs.


11:20 - 11:40

Like many developers, we had to deal with a back-end written in Ruby 1.8 and we discovered the awesomeness of Serverless. Migrating entire back-end at once is not a piece of cake but the capabilities of Serverless computing allowed us to migrate back-end from Ruby to AWS Lambda functions. We encountered lot of pitfalls along the journey and in this session I am planning to share my experiences on migrating legacy back-ends to Serverless and how to plan parallel migrations avoiding long waiting release cycles.

I know what you are thinking: Haxe is too good to be true.Q: Maybe Haxe provides only limited language features that the target languages support?A: No, Haxe provides class/interface, first-class function, pattern-matching, algebraic datatypes, and compile-time macros for all its targets.Q: Well, then implementing those must make the compilation output bloated and slow?A: No, the Haxe compiler provides inlining, static analysis, and dead-code elimination that can provide better performance than using the target languages directly.Q: Its compiler must be big and takes forever to compile.A: No, a Haxe installation is less then 30MB. Compilation is super fast - much faster than typical C++/Java compilers when compiling large projects.Q: How can this awesome language not be popular?A: We don’t have a marketing team and our community is relatively small. We think it is time to present Haxe to more people - that’s why we have this talk!


11:35 - 11:55

The presentation will include the most recent events and updates regarding PetaBencana.id and the monsoon season in Indonesia. PetaBencana.id is a community-led, open source risk map for Indonesia; the project is supported by the Humanitarian Infrastructures Group of the Urban Risk Lab at MIT, with the aim of further developing CogniCity Open Source Software as a free, transparent, enterprise-level platform for emergency response and disaster management in megacities in South and Southeast Asia. As these cities become increasingly complex systems of people and interconnected infrastructure, extreme weather events and long term environmental changes pose acute challenges for disaster response and humanitarian action.Although rapidly urbanizing environments are often thought to be “data scarce,” by enabling residents to share emergency data openly and in real time, PetaBencana.id makes a wealth of information available that promotes resilience to extreme weather events. By gathering, sorting, and visualizing data, PetaBencana.id transforms the noise of social and digital media into critical information for residents, communities, and government agencies. The platform adopts a “people as sensors” paradigm, where confirmed reports are collected directly from the users at street level in a manner that removes expensive and time-consuming data processing. This framework creates accurate, real-time data which is immediately made available for users and first responders. The CogniCity OSS was designed, tested, and deployed as an operational platform in Jakarta during a three-year (2013-2016) applied research project. As a “proof of platform,” the free web-based flood map PetaJakarta.org was used by hundreds of thousands of residents during monsoon flooding. It is was also adopted by the Jakarta Emergency Management Agency (BPBD DKI Jakarta) to monitor flood events, to improve response times, and to share emergency information with residents. CogniCity OSS proved the value of crowdsourced social and digital media for emergency response through the PetaJakarta.org platform, but this use of open data for humanitarian disaster response is only a first step. Additional CogniCity OSS modules are in development at the MIT Urban Risk Lab to address other hazards, including earthquakes, volcanoes, tsunamis, typhoons, and terrorism. CogniCity OSS is also being designed to integrate and coordinate additional data sources, including various instant messaging services. And, as CogniCity OSS is deployed as a disaster risk management system in other Asian megacities, additional platform extensions and innovations will provide additional support for humanitarian response to urban disasters.

Load balancing is the process of improving the performance of distributed systems by distributing server load amongst the system processors. In client-server systems, and especially when there is heavy load, load balancing is a crucial process in maintaining quick response times for clients. Many algorithms - both static and dynamic - have been developed for this. The talk will focus on the working of these algorithms and utilities in place today which facilitate efficient load balancing, and analyse their performances

The Shogun Machine learning toolbox provides a wide range of unified and efficient Machine Learning (ML) methods. The toolbox seamlessly allows to easily combine multiple data representations, algorithm classes, and general purpose tools. This enables both rapid prototyping of data pipelines and extensibility in terms of new algorithms. We combine modern software architecture in C++ with both efficient low-level computing backends and cutting edge algorithm implementations to solve large-scale Machine Learning problems (yet) on single machines.One of Shogun's most exciting features is that you can use the toolbox through a unified interface from C++, Python, Octave, R, Java, Lua, C#, Ruby, etc. This not just means that we are independent of trends in computing languages, but it also lets you use Shogun as a vehicle to expose your algorithm to multiple communities. We use SWIG to enable bidirectional communication between C++ and target languages. One of the focus point of the talk is the introduction of the meta-example framework developed as part of the toolbox: a user can write an example use-case for a method using our 'meta-example' syntax, that would then be auto-translated into all of the supported languages of the library. This not only allows us to easily scale with the number of new methods in the sense of having the example use-cases of the method being exposed to all of the target languages, but it allows us to have those methods tested throughout of all the languages.Originally focussing on large-scale kernel methods and bioinformatics, the toolbox saw massive extensions to other fields in recent years. It now offers features that span the whole space of Machine Learning methods, including many classical methods in classification, regression, dimensionality reduction, clustering, but also more advanced algorithm classes such as metric, multi-task, structured output, and online learning, as well as feature hashing, ensemble methods, and optimization, just to name a few. Shogun in addition contains a number of exclusive state-of-the art algorithms such as a wealth of efficient SVM implementations, Multiple Kernel Learning, kernel hypothesis testing, Krylov methods, etc. All algorithms are supported by a collection of general purpose methods for evaluation, parameter tuning, preprocessing, serialisation & I/O, etc; the resulting combinatorial possibilities are huge.

gcc helloworld.c -o helloworld.htmlIf you are C / C++ programmer and see this command line, you will say: "Oh dear, C compiler emits HTML"Actually, this gcc does not emit HTML from C codes, but some compilers do.This means the web is a new compiler target architecture, like x86 and arm.In other words, we can implement our web sites with C / C++. WebAssembly is the key technolgy for it.This new, portable size- and load-time-efficient binary format for web browsers, is emmited by C / C++ compilers.Web browsers compile it into the native code, so we can speed up our web apps with it.In this talk, we will overview this new technlogy:WebAssembly specs, how C codes are compiled into it, and typicical use cases.

DIY microbial fuel-cell: making microbes make electricity. With mud."Without the midi-chlorians, life could not exist, and we would have no knowledge of the Force. They continually speak to us, telling us the will of the Force. When you learn to quiet your mind, you'll hear them speaking to you." -- Qui Gon Jinnhttp://starwars.wikia.com/wiki/Midi-chlorianhttps://media.giphy.com/media/rCTbP4dY9kUPm/giphy.gifIRL Midi-Chlorians are akin to Microbes.Microbes power you. You have more bacterial cells than YOU cells that make you you. Non-human cells outnumber human cells by a factor of (at least) 1.3 does this mean we're more alien than we think? Could we harness the power of "The Force" by harnessing the power of these microbes?We're interested in 2 MagicalMicrobes: SHIWANELLA and GEOBACTER​​​​​​​. They live in MUD and can produce electricity. They're quite happily found anywhere on the surface of the planet Earth, which conveniently is where we all live.In this workshop we'll be using mud to make your very own fuel-cell powered by magical microbes. We'll talk about how this works, and wire up a tiny circuit that harnesses this tiny microbial power to produce light. This is a hands-on experimental workshop where we play with mud as an excuse to talk and discuss about microbes, fuel-cells, and their practical / impractical uses.Mud, Materials, Gloves, and hand-sanitzer all provided. Come play with mud.

The goal for this discussion is to increase the likelihood that usability will become a core value in open source software development by creating common ground for people with direct experience in development and design. We will review existing cases of UX design contribution to open source projects and discuss what contributors can do to improve usability of the software they build.


12:25 - 12:45

The motive is not to criticize Artificial Intelligence as the past, as the name of the talk suggest. Instead, it's to summarize the advancement made in the recent past, mainly since 2016 Q3. However, the summary may never be exhaustive. So, the focus will be on impact rather than implementation. The talk will give sneak peek into the interesting projects that AI gave to the world through large corporations or individuals. Majority of them are developed using Machine Learning than anything else in AI.

The software licenses are the permissions over copyrighted software. The permission and/ grant includes the grant to use, to redistribute, to prepare derivative works etc. These software licenses also set forth the limitations over these aforesaid rights. The software licenses basically marks the boundary for the usage of the code.Therefore from the above mentioned introduction it very clear that it is very important for developers to choose the license for their code wisely and correctly.Pypi, the Python Package Index is a repository of software for the Python programming language. There are currently 80000+ packages there.This talk will go through the licenses of the top 2500 packages. We will see the trend of choosing a license for these top Python projects. We will discuss the licenses individually, compare them with each other. the advantages and disadvantages of the same.We will further explain that why a license and/or licenses are being favoured by the developers.Outline of my talk:Introduction of the SpeakerWhat is Copyright?What is a software license?The Kinds of licensesWhat is the PyPI project?Graphs and charts explaining the license usagePython Packages in Fedora landDetails of these FOSS licensesThe advantages and disadvantages of various FOSS licensesComparison of the sameWhat are the points to be kept in mind while choosing a license

The KDE community has always strongly believed in openness, in free and open source software. Today, we’re taking this mission one step further, by bringing openness to the most important intellectual production of humanity: knowledge itself. And we’re not doing it alone, but with the help of institutions and professors all around the globe.

What is WikiToLearn? WikiToLearn is an open platform where students, researchers and key people in the academia can create and refine notes and text books, tailored precisely to their needs, and giving them the power to customise the teaching beyond what traditional textbooks allow. Our philosophy inherits from the very foundation of how science works. We believe that “Knowledge only grows if shared” and we want learners to “Stand on the shoulder of giants!”

Why is it an innovation?WikiToLearn does not offer new knowledge. WikiToLearn offers a new approach to knowledge: it rediscovers and repurposes the attitude, now almost forgotten by mankind, that led our civilisation to take the huge steps that have brought us here today, with our endless heritage of knowledge. Without the collaboration and the communication among the people, without the free availability of knowledge, no big discovery would have been possible. This is what we are trying to restore. We are driven by the love for free knowledge, owned by no one and accessible to everyone. As volunteers, freely collaborating between us, we want to make this vision possible. Open source gains in this context a profound and significant meaning, merging naturally with our philosophy.Any content can be modified: this leads to a continuous development of the existing material, to the collaboration and communication among learners.Everything on WikiToLearn is freely accessible and can be downloaded: in this way knowledge is made available to everyone.

Why should I contribute?It is really important that users contribute to the writing and the improvement of the contents. This is the only way the project can be successful and be able to continue to grow. Your contribution, as small as it could be, is and will always be fundamental.Finding already existent, well organised and freely accessible material can be really useful. However, always bear in mind that you can find it only because someone decided to contribute to creating it.

Moved/Driven by what? Perhaps by our same vision: the desire to see, at last, a change in the approach to knowledge. Perhaps because so you can really feel useful and part of something great, with the power change the world.

Who can contribute?

  • I’m a university student, I don't have time for this...Your contribution is, of course, not solely dedicated to making WikiToLearn bigger: writing and summarising are excellent tools that will help you to prepare for exams, as well as to improve your explanation skills. Moreover, this is often the best way to realise what you did not understand, and in case you make a mistake, someone will correct you.
  • But I'm a professor!- WikiToLearn is an excellent workout for the students, but it is also a really useful tool for the teachers.Reviewing the notes of your students will help you to be aware of their understanding of each lesson, which gives you valuable feedback on the effectiveness of your teaching. You can then customise your classes in order to optimise the educational path.The students will consolidate their knowledge by writing their notes in a more organised way and, thanks to your thorough checking and improving, they will be able to create evolving, evolving, exhaustive, proofread and beautifully formatted textbooks.

Today, even low-end computers have resources once only found in supercomputers. Similarly, there is a huge selection of free professional-quality software, in particular (but not only) related to Science, Technology, Engineering, and Mathematics (STEM). Yet all too often, students are only taught to use computers for basic word processing or presentations and never learn to tap the computer’s power as a versatile problem-solving tool, even if it could be readily applied at school, in their future careers, and at home.

In my presentation, I will demonstrate a few examples of free software we use routinely in our STEM teaching and research lab in areas such as computer-assisted mathematics, mechanical design, electronic circuit design, and data analysis.

The ultimate key to take control of the computer as a tool is the ability to program it. The Python programming language is rightfully popular in education, academia and industry alike as it is easy to learn, yet extremely expressive and powerful. I will show examples of how we/our students use Python to simulate engineering designs before prototyping, control experiments, and acquire and process data.

I will close by discussing why free software is not just about the money, and how some attractive-looking free-of-charge software or online service schemes can actually hurt students by taking their freedom away.

The workshop gives hands on experience on developing a fresh MediaWiki extension from scratch using the BoilerPlate extension, and goes step by step to deliver the following: * Correctly coupling the extension with the Mediawiki core (prerequisite of attendees to have Mediawiki core already cloned with LAMP stack running recommended) * Implementing a Hook to listen to an event (An example: Page title move in a particular namespace event to show some message on the screen)* Coupling with Echo extension to show up a notfication (The 'some message' in step 2 to be changed with a notification using Echo). If time allows, add more stuff to the notification etc. Hooks and notifications are two things which almost every human-interacting extension on MW use, hence this workshop would be fruitful for interested students to take a look at how Mediawiki core + extensions work, and how the control flows on an event. This is in wake of the approaching Google Summer of Code + Outreachy round, and I hope to get participants of the eligible audience for the same.

Java-the-language has a reputation of being boring and predictable, but the Java Virtual Machine is a different story. Underneath the familiar facade of the Java language, the Java Virtual Machine is dynamic, unpredictable, and moreclosely resembles a living organism than the deterministic clockwork peoplenormally imagine their programs to be.This talk will explore the hidden dynamics of the Java Virtual Machine. We willexplore the world of memory layouts, garbage collection, JIT compilation, walking through the behavior of many real-world code examples. By the end of this talk, you should be much more familiar with the inner workings of the JVM that many of us take for granted, and hopefully will be better prepared to respond next time your Java application goes bump in the night.


15:15 - 15:35

I will be giving an introduction to what were the accomplishments in Open Event Android specifically the apk generator which is something that has never been done before. The generator takes in some inputs from the user and then clones the open event android app source to a google cloud machine. Now the app is customised according to the user's preferences and then an apk is sent to the user on their email and also available to download from there itself.


15:15 - 15:40

Usability tends to be mostly common sense, usability testing is a journey to discover the potential issues for your users' experience. When we doing the usability testing, we can get the objective result, how many tasks have been finished, how many errors user did in this process, but one thing can drive our product to be much more better is user like it. the inside pleasure from user, the subjectivity is also much more important.

15:45 - 16:10

Every open source project will tell you that they want more design contributions and that they want their project to be easy to use, beautiful, modern, etc. Still there are lots of complains that is hard to have a designer integrated inside the community. So, is this true? Is there a mismatch between the designer and the community? Are there differences in participants' expectations?- Should the designer be involved in the project from the beginning to the end? - Should the designer be also a technical person? - Should the designer be responsible for the implementation of his proposals? - What we request in a design work is realistic and according to designer's specialty? - How can we evaluate a designer's proposals inside our community? - Can we have more than one designer involved in the community? - Do we know our target and provide full specifications when requesting design work? - Who should have the final decision on design proposals? - Is the designer responsible for all the usability problems of the project?- Why it is so easy to provide design feedback?- etc.All the above are valid questions when interacting with designers in open source communities and some times the answers don't match. Stating very clear what the expectations are can be helpful in having long term design contributions. In this presentation we will go over the common questions and expectations designers and open source communities have and try to provide a base for design work interactions.

The MySQL Group Replication feature is a multi-master update anywhere replication plugin for MySQL with built-in conflict detection and resolution, automatic distributed recovery, and group membership. MySQL released GA version of Group Replication plugin on Dec 12 2012 (MySQL 5.7.17).MySQL Group Replication provides distributed state machine replication with strong coordination between servers. Servers coordinate themselves automatically when they are part of the same group. The group can operate in a single-primary mode with automatic primary election, where only one server accepts updates at a time. Alternatively, for more advanced users the group can be deployed in multi-primary mode, where all servers can accept updates, even if they are issued concurrently. There is a built-in group membership service that keeps the view of the group consistent and available for all servers at any given point in time.

Open Source photography typically has been about the software, but that's wrong. It's about the community, about people—the most integral and vibrant part. It's about sharing, working together, and making a positive difference. Without the right medium, the vibrancy of our communities is lost.By coming together, as a hobbyist or professional, we'll learn from each other about how to improve imagery all around. And we’ll help show the Open Source community’s greater impact on the world as a whole.


16:15 - 16:40

Art, design, and cultural events and organisations have proliferated in Indonesia in various scales. Designers, artists, researchers, environmentalists, handymen, technologists, hobbyists, entrepreneurs and government use open source licenses and tools mixed with assemblages of media technologies, “pirated” softwares and hardwares. Using two case studies, i.e. (1) Design It Yourself conference in Surabaya; and (2) Senayan SLiMS, an open-source Library Management Systems, I elaborate how various individuals and organisations (de)couple, calibrate, cobble up repair and maintenance in facing social or environmental challenges and emerging technologies in Indonesia. And how in the process, they generate networks of solidarity, tension, innovation, power, breakdown and resilience, across different boundaries.


16:20 - 16:40

The MySQL Replication Team at ORACLE has been striving to provide community with great replication features. It is time to celebrate again.

The Brainduino Project, Brain-Computer Interfaces and AI in the Future
The Brainduino Project, Brain-Computer Interfaces and AI in the Future (11:45 - 12:05)

About the session

In the recent years, EEG brain-computer interfaces are becoming popular and more accessible to consumers. Applications range from controlling computers, machines, biofeedback, to quantified self tracking. At first sight, the current generation of commercial devices seem to be decent in their functionality, and various use cases are suggested. However, neurophysiological signal quality, as well as limitations of software and hardware hackability are among the greatest issues and hurdles towards advancement in user experience. This is why we started to work on Brain-Duino, an open-source brainwave amplifier shield for the Arduino and other microcontrollers.

Brain-Duino is a high quality, low noise and affordable EEG / BCI for hackers, makers, researchers, artists and other enthusiasts. This talk will be about how the Brain-Duino project started, where it is now and where it is going. We will briefly explain how EEG brain-computer interfaces work, and also why this topic is relevant, together with the current advances in artificial intelligence and hardware.

During the FOSSASIA you will have the chance to try out the Brain-Duino and visualize your brainwaves.

About the session

As society and technology become more deeply intertwined, society is taking interest in -- and influencing -- nuanced technological issues, ranging from net neutrality, to the selection of emojis, to the enforcement of open source licenses. The FOSS community takes for granted the values of open source, but the benefits can be difficult to explain to those who are not empowered to utilize the source. This talk examines some of the cultural and technological barriers that have stymied inclusiveness, using gender imbalance as a case study. Finally, we propose a solution which we call "Love to Code", which attempts to address the issue of inclusiveness in technology.

Massive Multi-node setup with Postgres and BDR in Retail System
Massive Multi-node setup with Postgres and BDR in Retail System (10:55 - 11:45)

About the session

In Distributed System, such as Centralized Retail System like Hypermarket, there are 2 approaches for data collection and integration. Use Webservices or use Distributed Databases. By enabling Distributed Databases, and maintained it as if single integrated system, we can achieve simplicity, no context producer and subscriber anymore. this saves a lot of effort, time and resources of course. There are no worry about data synchronization, no need to maintain data Integrity with much effort. In this talk, we will cover about why and how BDR (Bidirectional Replications) implemted in high performance transaction system (which we developed, i.e POS Retail System). Why that matter and how this can be a great lesson for any other implementation.

How to teach an elephant to dance rock'n'roll
How to teach an elephant to dance rock'n'roll (13:00 - 13:50)

About the session

Unconventional query optimization in PostgreSQL, or how to teach an elephant to dance rock'n'roll.Query performance is usually tuned by simply adding indexes and rewriting the query minimally, while the basic idea of the query stays the same. For many query, this is not the best way to optimize them: you need to rethink and rewrite them completely. To do this, you need to know how optimizer and executor work, and keep that in mind while composing your queries. In this talk, I will present an overview of a few less known and rarely used techniques such as:* using and implementing loose index scan for different scenarios;* using IOS in situation where it isn't applicable directly;* replacing IN (long list of values) with JOIN VALUES ();* moving a limit or offset clause inside joins;* and other tricks with row types and arrays of row types.Using these techniques and some other ideas, we will learn how to optimize a 'friends feed/subscription news' query, which is a typical task in many projects. We will diretcly compare performance of four different approaches: direct approach (simplest query), optimized direct approach (more complicated version of it), pl/pgsql with different algorithms, and implementation of this pl/plsql code in plain sql. I will show how this approach can convert almost any read-only non-dynamic (no EXECUTE statements and no exceptions) pl/pgsql code to a plain sql query.

Running Highly Available Postgres in AWS RDS
Running Highly Available Postgres in AWS RDS (14:00 - 14:50)

About the session

If we look back and see the changes that have happened in last few years, we will realize that how things have changed very rapidly. A decade back, most of the organizations either would have their in-house database servers running on certain hardware and storage configuration. Over the period, when the servers become obsolete, then server/storage migration would itself become separate project and the procurement process for new hardware in any organization is usually time consuming process. In last two years, there has been rise in adoption of Cloud that tries to address this and many other issues. Now you do not have to worry about the underlying hardware and storage, once you know CPU, RAM and storage requirement, you can customize the server and build your own server in cloud. Also, migrating Postgres cluster to cloud is a viable option for safety (no data loss, including if rollback), minimal downtime (switchover and rollback), minimal effort for the team.Considering one of the above reasons for moving to cloud, one of our client’s in FinTech space decided to move their PostgreSQL instance to AWS RDS since RDS offered some of the following benefits like:• Automated failover of primary in case of failure • Automated creation of replicas• Automated updates• A purely declarative setup, via Cloud formationHere I will talk about how technical aspects of moving PostgreSQL server to AWS RDS.• How to configure, tune the parameters in config file while moving onto RDS. • How you can select the storage depending upon growth estimate and IOPS requirement• How you can configure HA setup in RDS.• How you can distribute your reporting workload.• How to monitor Postgres instance and alert configuration

PostgreSQL Security. How Do We Think?
PostgreSQL Security. How Do We Think? (16:30 - 17:20)

About the session

In recent years, applicable area of PostgreSQL has quickly extended into the enterprise sector thanks to continuing effort of the community to improve performance and functionality. As a result, there is an emerging demand to use PostgreSQL in more security-critical circumstances.In this presentation, I will talk about the following two topics. * Considerations for securing a database system. * Current status of database audit on PostgreSQLI am working for the open source software center (OSS center) of NTT which is the largest telecommunications company group in Japan. We have encouraged many of our customers to migrate a lot of database systems to PostgreSQL so far and this contributed much to cost reduction.Some projects need to conform to security standards, for example PCI DSS (Payment Card Industry Data Security Standard). It is one of the most prevailing security standard in the world. However it is not easy to build and operate a PostgreSQL-based system conformant to these security standards. I'd like to describe some aspects required for secure database systems in general, such as encryption, key management, identity management and auditing.Then I explain considerable points for building a secure database system using PostgreSQL, and show the remaining challenges for secure database systems using PostgreSQL.Finally, I introduce a forked version of pgaudit that we are maintaining, then explain how to use it. pgaudit is developed by 2ndquadrant and Crunchy Data, especially by David Steel with a great contribution. However, it does not meet our customer's requirements. For example, It cannot output the audit log and server log separately, it cannot audit Superuser fully, etc. So we forked it and added some changes.

About the session

There are many architectures starting with MV* prefix. I've got experience creating many apps with all of them and now I prefer to use MVVM. This talk is about why and how I solve many common problems of android developers using this approach. Model–view–viewmodel (MVVM) is a software architectural pattern. MVVM facilitates a separation of development of the graphical user interface – be it via a markup language or GUI code – from development of the business logic or back-end logic (the data model).
