  • Community Participants (unlimited): Digital Certificate of Participation (with at least 5 merged pull requests)

What are the Judging Criteria

Our jury will review the work of the 10 developers who have the highest number of quality contributions during the contest. Contributions include pull requests/code commits, scrum reports, articles, screencasts, community engagement and outreach activities. The mentors will look at the:  

Sustainability, which means that we specifically value contributions that make the project sustainable by building a community where developers collaborate with each other in a friendly way and support the project development through peer reviews, on-boarding new members, and helping fellow contributors. It also means that, while code is the most important success criteria for winning the contest, furthermore we are looking for contributions in other areas to make projects easy to join, to deploy and to use. This includes:

  • creating and enhancing documentation
  • developing how-tos
  • writing technical blog posts
  • sharing work in regular scrum updates to enhance communication
  • organizing local meetups, workshops, presentations 

Quality vs. Quantity: The sheer number of pull requests is not the only criteria for choosing the winners. Quality work is appreciated – some issues are more challenging than others just by their nature (for example, heavy coding versus solving a text typo bug). It is entirely possible that someone who completed 53 issues could be chosen as a winner over someone who completed 88 issues.

How Are the Winners Decided

  • Grand Prize Winners: Three developers will be selected by mentors from the top 10 contributors according to code quality, relevance of commits and contributions that help to bring the project forward.  
  • Finalist Winners: After the grand prize winners are selected, the remaining seven contributors of top the 10 will receive finalist winner prizes.
  • Other contributors who have more than 10 merged pull requests during the contest will receive a Thank you package. Anyone who has 5 pull requests merged will receive a digital certificate.

Open is Becoming the New Common Foundation across Business, Government, Science, and Industry

Interview with Shanker V Selvadurai, Vice President & Chief Technology Officer of Cloud and Cognitive Software for IBM Asia Pacific

Could you briefly introduce yourself?

I am Shanker Selvadurai and currently the Vice President & Chief Technology Officer of Cloud and Cognitive Software for IBM Asia Pacific. I am based in Singapore and lead the technical organization that helps clients across Asia Pacific to explore and co-create cloud-based solutions that leverage data, analytics and artificial intelligence (AI) capabilities to deliver better decisions and outcomes.

I joined IBM in 2006.  Prior to IBM, I held key leadership positions in areas of research, development, consulting, sales and marketing with technology companies like AT&T, NCR and Fujitsu as well as start-up BlueGill Technologies. During this period I lead teams varying in size from 6 to over 1,000 while being based in North America, Europe and Asia.

I have a Bachelor of Science degree and a Master of Business Administration. I am also an Open Group Certified Distinguished Architect. Besides having published international patents/papers, I have actively contributed to international technology standards committees that include the IFX Forum, OFX Consortium and the Microsoft Advisory Council. I was also an adjunct lecturer at the Singapore Management University, teaching courses related to Services Science and Advanced Business Technology.

Tell us about your session at the FOSSASIA Summit, what will you cover?

At the FOSSASIA Summit, I am participating in a panel on “Business, Government, Science – What Opportunities Does “Open” Bring to Society”.  I hope to share IBM’s involvement in the open source movement, how businesses like IBM benefit from open source, as well as share thoughts about approaching open contribution and open governance in the future.

Shanker V Selvadurai handing over IBM Cloud Prize for Hackathon Winners

Business, Government, Science – What Opportunities Does “Open” Bring to Society from your point of view?

Open is becoming the new common foundation across business, government, science, and industry today.  For example, companies that still compete head-to-head in the marketplace are coming together to collaborate in open source communities.  They contribute to open source software and use it in their own IT systems and applications. They gain a competitive advantage — even though they may be helping their competitors in the short run.  The data demonstrates that companies with open source programs see more benefits from open source code and community participation.

What was your motivation to work for IBM and to participate in the FOSSASIA Summit?

IBM has a long history as a leader in, and supporter of open source communities, most notably in the Apache, Linux, and Eclipse Foundations.  I joined IBM to help continue this tradition and I am looking forward to discussing new ideas to help build the future of open source at FOSSASIA Summit.

Which FOSS projects in the area of cloud and AI can interested developers contribute in IBM? In which domains could you use some help?

IBM believes that communities with open governance and an inclusive philosophy will attract the largest ecosystems and markets.  For a listing of some of the top open source projects that IBM believes represent significant opportunity areas, I would like to share with information how IBM supports high-impact open source projects here.

Participants from Around the World Following IBM Keynote on FOSS Collaboration

Which new features can we expect in IBM cloud and AI this year? Do you plan to release any new projects as FOSS?

Most of our strategic initiatives today are founded on open source projects or communities (Cloud Native Computing, Hyperledger, CD Foundation, etc.), and we work across a wide variety of internal stakeholders to ensure that that the contributions we make to the community also provide greater value to our clients. For a specific example of open source innovation from IBM, please check out the Egeria Project, which was founded in part by IBM.

Shanker V Selvadurai with Panelists and FOSSASIA Founder Ms. Hong Phuc Dang at the Singapore Summit 2019

As well, at the FOSSASIA Summit in Singapore, IBM shares the “Call for Code Global Challenge, which IBM is the Founding Partner.  

This multi-year global initiative rallies developers to create practical, effective, and high-quality applications based on cloud, data, and artificial intelligence that can have an immediate and lasting impact on humanitarian issues.  Call for Code brings startup, academic, and enterprise developers together and inspires them to solve the most pressing societal issues of our time. Building on the success of the 2018 competition, the 2019 Call for Code Global Challenge again asks developers to create solutions that significantly improve preparedness for natural disasters and accelerate relief when they hit. This year’s challenge introduces an emphasis on individual health and community wellbeing. This includes solutions that can reduce the risk of disease, improve access to data and the availability of resources, and address the mental health needs of those impacted before, during, and after disasters.

Building SUSI.AI Android App with FDroid

Fdroid is an app store for Free and Open Source Software (FOSS). Building and hosting an app on Fdroid is not an easy process compared to when we host one on Google Play. A certain set of build checks are required to be done prior to making a merge request (which is similar to a pull request in GitHub) in the fdroid-data GitLab repository. SUSI.AI Android app has undergone through all these checks and tests and is now ready for the merge request to be made.

Setting up the fdroid-server and fdroid-data repositories is a separate thing and is fairly easy. Building the app using the tools provided by fdroid is another thing and is the one that causes the most problems. It will involve quite a few steps to get started. Fdroid requires all the apps need to be built using:

$ fdroid build -v -l ai.susi

This will output a set of logs which tell us what went wrong in the builds. The usual one in a first time app is obviously the build is not taking place at all. The reason is our metadata file needs to be changed to initiate a build.

The metadata file is used for the build process and contains all the information about the app. The metadata file for a.susi package was a .yaml file.

Builds:

 – versionName: 1.0.10

   versionCode: 11

   commit: 1ad2fd0e858b1256617e652c6c8ce1b8372473e6

   subdir: app

   gradle:

     – fdroid

This is the metadata reference file’s build section that is used for the build process using the command that was mentioned above.The versionName a nd versionCode is found in the build.gradle file in the app and commit denotes the commit-id of the latest commit that will be checked out and built, subdir shows the subdirectory of the app, here the subdirectory is the app file.

Next is the interesting stuff, since we are using flavors in the app, we have to mention in the gradle the flavor which we are using, in our case we are using the flavor by the name of “fdroid” and by mentioning this we can build only the “fdroid” flavor in the app.

Also when building the app there were many blockers that were faced, the reason for the usual build fails were :

1 actionable task: 1 executed
INFO: Scanning source for common problems…
ERROR: Found usual suspect ‘youtube.*android.*player.*api’ at app/libs/YouTubeAndroidPlayerApi.jar
WARNING: Found JAR file at app/libs/YouTubeAndroidPlayerApi.jar
WARNING: Found possible binary at app/src/main/assets/snowboy/alexa_02092017.umdl
WARNING: Found possible binary at app/src/main/assets/snowboy/common.res
ERROR: Found shared library at app/src/main/jniLibs/arm64-v8a/libsnowboy-detect-android.so
ERROR: Found shared library at app/src/main/jniLibs/armeabi-v7a/libsnowboy-detect-android.so
INFO: Removing gradle-wrapper.jar at gradle/wrapper/gradle-wrapper.jar
ERROR: Could not build app ai.susi: Can‘t build due to 3 errors while scanning
INFO: Finished
INFO: 1 build failed

The reason for these build fails were that fdroid does not allow us to use prebuilt files and any proprietary software if present, the above log indicates the two prebuilt files which should be removed and also the YouTubeAndroidPlayerApi.jar which is proprietary software and hence needs to removed. So, to remove the files that are not used in the fdroid flavor and exclude them in the build process, we have to include the following statements in the build section of the metadata reference file :

   rm:
     – app/src/main/jniLibs/arm64-v8a/libsnowboy-detect-android.so
     – app/src/main/jniLibs/armeabi-v7a/libsnowboy-detect-android.so
     – app/libs/YouTubeAndroidPlayerApi.jar

Once the metadata file is complete we are ready to run the build command once again. If you have properly set the environment in your local PC, build will end successfully assuming there were no Java or any other language syntax errors.

It is worth to mention few other facts which are common to Android software projects. Usually the source code is packed in a folder named “app” inside the repository and this is the common scenario if Android Studio builds up the project from scratch. If this “app” folder is one level below the root, that is “android/app”, the build instructions shown above will throw an error as it cannot find the project files.

The reason for this is as it is mentioned “subdir=app” in the metadata file. Change this to “subdir=android/app” and run the build again. The idea is to direct the build to find where the project files are.

Building PSLab Android app with Fdroid

Fdroid is a place for open source enthusiasts and developers to host their Free and Open Source Software (FOSS) for free and get more people onboard into their community. Hosting an app in Fdroid is not a fairly easy process just like hosting one in Google Play. We need to perform a set of build checks prior to making a merge request (which is similar to pull request in GitHub) in the fdroid-data GitLab repository. PSLab Android app by FOSSASIA has undergone through all these checks and tests and now ready to be published.

Setting up the fdroid-server and fdroid-data repositories is one thing. Building our app using the tools provided by fdroid is another thing. It will involve quite a few steps to get started. Fdroid requires all the apps need to be built using:

$ fdroid build -v -l org.fossasia.pslab

 

This will output a set of logs which tell us what went wrong in the builds. The usual one in a first time app is obviously the build is not taking place at all. The reason is our metadata file needs to be changed to initiate a build.

Build:<versioncode>,<versionname>
    commit=<commit which has the build mentioned in versioncode>
    subdir=app
    gradle=yes

 

When a metadata file is initially created, this build is disabled by default and commit is set to “?”. We need to fill in those blanks. Once completed, it will look like the snippet above. There can be many blocks of “Build” can be added to the end of metadata file as we are advancing and upgrading through the app. As an example, the latest PSLab Android app has the following metadata “Build” block:

Build:1.1.5,7
    commit=0a50834ccf9264615d275a26feaf555db42eb4eb
    subdir=app
    gradle=yes

 

In case of an update, add another “Build” block and mention the version you want to appear on the Fdroid repository as follows:

Auto Update Mode:Version v%v
Update Check Mode:Tags
Current Version:1.1.5
Current Version Code:7

 

Once it is all filled, run the build command once again. If you have properly set the environment in your local PC, build will end successfully assuming there were no Java or any other language syntax errors.

It is worth to mention few other facts which are common to Android software projects. Usually the source code is packed in a folder named “app” inside the repository and this is the common scenario if Android Studio builds up the project from scratch. If this “app” folder is one level below the root, that is “android/app”, the build instructions shown above will throw an error as it cannot find the project files.

The reason behind this is we have mentioned “subdir=app” in the metadata file. Change this to “subdir=android/app” and run the build again. The idea is to direct the build to find where the project files are.

Apart from that, the commit can be represented by a tag instead of a long commit hash. As an example, if we had merge commits in PSLab labeled as “v.<versioncode>”, we can simply use “commit=v.1.1.5” instead of the hash code. It is just a matter of readability.

Happy Coding!

Publish an Open Source app on Fdroid

Fdroid is a famous software repository hosted with numerous free and open source Android apps. They have a main repository where they allow developers hosting free and ad free software after a thorough check up on the app. This blog will tell you how to get your project hosted in their repository using steps I followed to publish the PSLab Android app.

Before you get started, make sure you have the consent from your developer community to publish their app on Fdroid. Fdroid requires your app to use all kind of open resources to implement features. If there is any closed source libraries in your app and you still want to publish it on Fdroid, you may have to reimplement that feature by any other mean without using closed source resources. They will also not allow to have Google’s proprietary “play-services” in your app along with proprietary ad services. You can find the complete inclusion policy document from their official page.

When your app is fully ready, you can get started with the inclusion procedure. Unlike how we are publishing apps on Google Play, publishing an app on Fdroid is as simple as sending a pull request to their main repository. That’s exactly what we have to do. In simple terms all we have to do is:

  1. Fork the Fdroid main data repository
  2. Make changes to their files to include our app
  3. Do a pull request

First of all you need a GitLab account as the Fdroid repository is hosted in GitLab. Once you are ready with a GitLab account, fork and clone the f-droid-data repository. The next step is to install the fdroid-server. This can be simply done using apt:

$ sudo apt install fdroidserver

 
Once that is done, go into the directory where you cloned the repository and run the following command to check if the initiation is complete.

$ fdroid init

 
Then run the following command to read current meta data where it saves all the information related to existing apps on Fdroid;

$ fdroid readmeta

 
This will list out various details about the current meta files. Next step is to add our app details into this meta file. This can be done easily using following command or you can manually create folders and files. But the following is safer;

$ fdroid import --url https://github.com/fossasia/pslab-android --subdir app

 
Replace the link to repository from the –url tag in the above command. For instance the following will be the link for fossasia-phimpme android;

$ fdroid import --url https://github.com/fossasia/phimpme-android --subdir app

 
This will create a file named as “org.fossasia.pslab” in the metadata directory. Open up this text file and we have to fill in our details.

  1. Categories
  2. License
  3. Web Site
  4. Summary
  5. Description

Description needs to be terminated with a newline and a dot to avoid build failures.

Once the file is filled up, run the following command to make sure that the metadata file is complete.

$ fdroid readmeta

 
Then run the following command to clean up the file

$ fdroid rewritemeta org.fossasia.pslab

 
We can automatically add version details using the following command:

$ fdroid checkupdates org.fossasia.pslab

 
Now run the lint test to see if the app is building correctly.

$ fdroid lint org.fossasia.pslab

 
If there are any errors thrown, fix them to get to the next step where we actually build the app:

$ fdroid build -v -l org.fossasia.pslab

 
Now you are ready to make the pull request which will then get reviewed by developers in Fdroid community to get it merged into their main branch. Make a commit and then push to your fork. From there it is pretty straightforward to make a pull request to the main repository. Once that is done, they will test the app for any insecurities. If all of them are passed, the app will be available in Fdroid!

Daimler: Our developers know about the advantages of Open Source Software
Mit fünf spektakulären Installationen hat Sarah Illenberger den Mercedes-Benz F015 Luxury in Motion in Szene gesetzt. Die renommierte Künstlerin arbeitete dabei im Spannungsfeld zwischen technologischer Zukunft und künstlerischer Handarbeit. Mit den Installationen übersetzte Illenberger die faszinierenden Eigenschaften des F015 in eine ausdrucksstarke Bildwelt, die dem Betrachter die Mercedes-Benz Vision vom autonomen Fahren näherbringt. Die Motive machen den Sprung in die neue Ära des Fahrens und die damit verbundenen Veränderungen begreifbar. Dabei wird automobile Ingenieurs- und Designleistung im besten Sinne zu Kunst. ; Sarah Illenberger has drawn attention to the Mercedes-Benz F015 Luxury in Motion by producing five spectacular installations. To do this, the renowned artist had to work between the poles of technological future and artistic handiwork. With these installations, Illenberger has translated the fascinating features of the F015 into an expressive pictorial world that brings the observer closer to the Mercedes-Benz vision of autonomous driving. The subjects take the leap into the new era of driving, rendering the associated changes touchable and comprehensible. This process sees automotive engineering and design achievements becoming art in the best sense of the word.;

Daimler: Our developers know about the advantages of Open Source Software

Vlado Koljibabic is Head of CASE IT at Daimler AG, the parent company of the car manufacturer Mercedes-Benz. He aims to strengthen the idea of Open Source in his company. Daimler is a partner of FOSSASIA. Torben Stephan interviewed Koljibabic on the advantages of open source software.

Stephan: What does CASE stand for?

Koljibabic: CASE is the combination of everything disruptive regarding our business: Connected, Autonomous, Shared & Services and Electric. These topics shall help us to transform from a car manufacturer to a mobility services provider. This is key in order to remain successful in the future.

How much Free and Open Source Software (FOSS) is actually part of a Mercedes?

We have been using FOSS for many years. Any Mercedes-Benz comes with a CD full of FOSS licenses. Every license belongs to a piece of open source software which is implemented in our cars. Even our Mercedes me app contains seven OS licenses. We use it because our developers know about the advantages of OSS.

Which are?

We don’t need to develop everything from scratch, we can reuse things where it makes sense and contribute to the development of open standards that increase efficiency throughout the system.

Daimler is a member of the “Automotive Grade Linux” (AGL) initiative initiated by the Linux Foundation. Isn’t that the right place for such open standards?

Absolutely. During FOSSASIA, with the community, we discussed the opportunity of defining an open standard for electric vehicle charging stations. From my point of view it definitely does make sense to develop this via the AGL. On the other hand Daimler might put even more commitment into this project to show we seriously want to be part of this.

Vlado Koljibabic CASE IT Daimler

What’s the advantage of open source software compared to proprietary?

Two things: Nobel Prize laureate John Nash showed that sharing of commodities brings advantages to all players in the market. For me this is the secret of the success of open source software. Beside this we can use existing software solutions for recurring processes. And the car industry is full of recurring processes. If there is no ready-to-use solution, we can initiate and design the processes and contribute to the community.

How do other business units within Daimler respond to this ideas?

For a company like Daimler these are huge changes. That’s why we do this step-by-step. First of all we convince our internal stakeholders of the reasonableness and the value of FOSS. As a following step we accelerate the topic within concrete projects. The overall process of enhancement of OSS usage is initiated and strategically supported. Jan Brecht the CIO of the Daimler AG drives and promotes the initiative essentially.

In which fields would you refrain from publishing your source code?

For example in highly sensitive areas in terms of competition. One example is Autonomous Driving – I would not be the first to focus on open source when it comes to this topic right now. But I’m sure that within the next years, there will be a deck of open source tools for Autonomous Driving, Machine Learning and Artificial Intelligence everyone can use.

Daimler uses a lot of open source. But what are you giving back to the community?

We are a member of the Linux Foundation and partner here at FOSSASIA. However, we don’t contribute source code yet in the context of open source projects. But we see the demand of the community and are working on it continuously to contribute as soon as possible.

Functioning App

An important point is, is the prototype or showcase functioning? We prefer real code and design implementations over mockups.

What to enter

Please submit a link to the app, a Github repo link and a short presentation as a download or on Google drive (ensure it is set to public sharing). You can also share anything else to demonstrate your work and let us test it.

  • Video: The platform accepts links to YouTube, Vimeo or Youku. If you like you can post a short video to demonstrate your work.

  • File Upload: There is also an option to upload a file. The platform allows submitters to upload one file, though they can combine files into a single ZIP file.

  • Other: The platform requires contestants to enter an entry name and description. Please also accept the the conditions of the contest including sharing your work under certified Open Source license.

Platform

Share information about what operating systems or devices can your hack run on.

Ressources

Include information about API, SDK, or data set, that are required to run the app.

New vs. Existing

Any work done need to be new for the competition. Existing apps are not eligible. However the specific details what is acceptable and what is not will be determined by the jury. For example existing apps that have been modified substantially and include entirely new functionality would still be eligible.

Submission Rights & Display

The submissions should be Open Source and licensed under a compliant Open Source/Free Software license. They should be upload to a Github repository.

We also request the right to use the winners’ names and work to promote the competition and hackathons in future.

Our jury will choose three winners from the top 10 contributors according to code quality and relevance of commits for the project. The jury also takes other contributions like submitted scrum reports and technical blog posts into account, but of course awesome code is the most important item on the list. Other participants will have the chance to win vouchers to attend Open Tech events in the region and will get certificates of participation. Sign up here now.

A team of over 30 mentors and jury members from 10 different countries supports participants of the contest.

Participants should take the time to read through the contest FAQ and familiarize themselves with the introductory information and Readme.md of each project before starting work on an issue.

The website codeheat.org has a list of questions and answers. Developers interested in the contest can also contact mentors on our Slack channel [Get a Slack Invite].

If you make at least four commits labeled “hacktoberfest” before 31st October you can also win a Hacktoberfest T-shirt (additional sign up required here).

GET and POST requests

If you wonder how to get or update page resource, you have to read this article.

It’s trivial if you have basic knowledge about HTTP protocol. I’d like to get you little involved to this subject.

So GET and POST are most useful methods in HTTP protocol.

What is HTTP?

Hypertext transfer protocol – allow us to communicate between client and server side. In Open Event project we use web browser as client and for now we use Heroku for server side.

Difference between GET and POST methods

GET – it allows to get data from specified resources

POST – it allows to submit new data to specified resources for example by html form.

GET samples:

For example we use it to get details about event

curl http://open-event-dev.herokuapp.com/api/v2/events/95

Response from server:

Of course you can use this for another needs, If you are a poker player I suppose that you’d like to know how many percentage you have on hand.

curl http://www.propokertools.com/simulations/show?g=he&s=generic&b&d&h1=AA&h2=KK&h3&h4&h5&h6&_

POST samples:

curl -X POST https://example.com/resource.cgi

You can often find this action in a contact page or in a login page.

How does request look in python?

We use Requests library to communication between client and server side. It’s very readable for developers. You can find great documentation  and a lot of code samples on their website. It’s very important to see how it works.

>>> r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
>>> r.status_code
200

I know that samples are very important, but take a look how Requests library fulfils our requirements in 100%. We have decided to use it because we would like to communicate between android app generator and orga server application. We have needed to send request with params(email, app_name, and api of event url) by post method to android generator resource. It executes the process of sending an email – a package of android application to a provided email address.

data = {
    "email": login.current_user.email,
    "app_name": self.app_name,
    "endpoint": request.url_root + "api/v2/events/" + str(self.event.id)
}
r = requests.post(self.app_link, json=data)
