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.

New web services, based on Artificial Intelligence technology approach quickly as intelligent digital personal assistants beyond the ability of simple chatbots.

Search engines will provide us with answers to all questions within the framework of conversational interfaces.

Free and open source implementations of digital assistants are challenged with the complexity of the conversational web ecosphere of smart devices and the ability to create intelligent skills out of cloud services.

The FOSSASIA community has worked hard to create such an ecosystem to establish a personal assistant framework for everyone based on the principle of privacy and collaboration.

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.

Welcome at the FOSSASIA Summit!

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.

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.

Which tracks and sessions do we have at the FOSSASIA Summit from Thursday (March 22) till Sunday (March 25)? In 12 tracks attendees can learn about the latest Open Source technologies and discuss topics from development to deployment and DevOps. We are bringing together some of the core track organizers and MCs to give you a super quick wrap up of what will happen over the next few days in tracks under the following header:

Join us for an Open Tech get together with coffee and snacks, meet speakers and developers and dive into the exhibition to explore companies and projects with us. This gathering is hosted by the FOSSASIA core team and our friends from Open Tech.

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).

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. 

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. 

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

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.

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. 

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

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?

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.

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).

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.

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.

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

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.

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.

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.

Kubernetes is taking a clear lead in container orchestration being adopted by all the major cloud/virtualization platforms (Google, Azure, probably AWS, VMWare).

This tutorial session will cover

• kubernetes concepts and architecture
• basic container orchestration using cli tools, apis (Python, Go)
• Exposing services
• scaling, rolling updates, rollbacks, healthchecks
• Kubernetes tools
•       cli such as kubectl, kubeadm, helper tools such as kubectx
•       higher-level tools such as Helm, Brigade
•       use of Traefik as an Ingress controller

Based on previous labs, all tutorial materials will be freely available during and after the session allowing students to just watch, or follow along on their own laptop or to run the tutorial themselves after the conference.

Students can just watch or follow along as they wish.

Online resources will be provided to run the labs either on the students own laptop or using their cloud account.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

Exhibition Stage

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.

Exhibition Stage

A brief intro to the Google Assistant

Artificial Intelligence in intelligent digital personal assistants are not simple chatbots. They are driven by the deduction rules of expert systems and the principle of machine learning. In this talk we learn how this technology is used in detail using the SUSI personal assistant framework. Rules - in the context of the conversational web now called ‚skills‘ - are implemented with the combination of a backtracking system combined with cloud access to external knowledge. We will learn how a expert system-based personal assistant works and why it can be very easy to write skills for such a system.

Having your chatbot handle your user’s conversational chatter gives it another dimension of personality and improves the experience. Explore how to build and train NLP models to handle freestyle conversation, and also attempt to make a bot clone of yourself. As a bonus, we will deploy the end result to smart speakers like Cortana on Invoke, and potentially Alexa or Google Home.

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. 

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.

Google Summer of Code and Google Code-In 

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.

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

 Tech for fun community and culture

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.

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. Jing Xuan shares the charged and explosive experience of building a railgun and coilgun, blowing up Arduinos and shooting nails backwards.

The FOSSASIA PSLab is the first Open Source Pocket Science Lab that can be used through the desktop and phones. The device is entirely Open Hardware, from the design itself, the firmware to the source code of the apps running on the phone. 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. The talk will demonstrate the device and provide insights into the specifics of the device, the functioning and our future plans.

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.

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. I will briefly sketch the animal and human research on this topic in Singapore. I will finish by taking a look at possible technologies to augment normal brain function in the future. 

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.

GCompris is a high quality educational software suite comprising of numerous activities for children aged 2 to 10.

Each activity can be considered as a fun game which mainly focuses on enhancing the learning of children through visual and graphics.The project is supported by KDE and is mainly written in QML,JS,C++ and QT.

GCompris is a free software, that means that you can adapt it to your own needs, improve it and, most importantly, share it with children everywhere. 

GCompris contain a variety of activities belonging to different domains. It spans from mathematical to language, from science to geography, from mouse coordination to computer typing and many more. Some of the activities are game orientated, but nonetheless still educational.

The topics of discussion under the talk are as follows :-

1.) Structure, Architecture, and Codebase of GCompris.

2.) The techstack of the project. 

3.) What are open source projects ? 

4.) How to contribute to GCompris ?

5.) Tutorial on git and github.

6.) Will motivate new comers to explore & contribute to open source world. 

The session will be very useful for new contributors who wished to contribute to GCompris and dive into open source world.

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.

Kamailio is an open source SIP (RFC3261) signalling server implementation developed since 2001. It targeted flexibility and scalability from the beginning, being currently used by large telecom and mobile operators world wide as well as global OTT services.

The talk is presenting the most common use cases of Kamailio, such as classic telephony platform, load balancer, least cost routing engine or SIP security firewall, aiming also to point to the relevant resources to help building the systems yourself.

Technology in recent years has allowed hobbyists to explore the radio spectrum around them for very low cost. This talk will be a discussion on how one can get started in SDR including what hardware to buy and an overview on what Open Source Software exists for use.

Some topics that will be talked about are antenna design, SDR cards, GNURadio, and how to improve signal reception.

Some of the radio spectrum applications that will be discussed are:

• AIS - Automatic Identification System for marine traffic
• ADS-B - Automatic Dependent Surveillance-Broadcast for air traffic
• Weather and satellite telemetry signals
• Improving security and preventing data leaks from RF signals

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.

Open Event Frontend is the new frontend project for eventyay. The talk will be focused on

• Introduction to the new frontend
• The best practices used in the project
• Data handling in ember js
• How we over came critical issues during the development
• How to start contributing to project

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. 

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.

Join the MySQL meetup and Community Gathering at the FOSSASIA Summit! We are meeting in the Lounge area in the exhibition.

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.

Join us for the Database Lightning Talks!

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. 

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.

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.

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.

It's that time again to push the boundaries of MySQL technology further. MySQL 8.0 is fully packed with tons of features with many of them are based on our community feedback & contributions.  Data dictionary, better security, better optimizer, better replication, and so on.  This session will talk about these exciting major improvements that promised to help you breaking through.  

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!

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.

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.  

When you heard about the Blockchain for the first time, you might have had a lot of questions about the technology.

What does it look like? How does it work? Is it secure?

Today, I will give a talk about the Blockchain from the miner's side.

After the talk you will know:

What is the Blockchain?

Who keeps it growing?

How is it secured?

You will also get hands-on experience with BTC mining and can mine some BTC yourself.

Blockchain technology is more than just cryptocurrencies - startups, established companies, and governments around the world are harnessing this exciting new technology to transform their businesses. Come learn how some of these enterpreneurs, enterprises, and public servants are building on blockchain and smart contracts and learn how you too can get started building your own applications!

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.

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.

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.

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.

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.

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?    

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.
