Google Code-in 2016: another record breaking year

Google Open Source Blog - 6 hours 17 min ago
Today we celebrate the closing of the 7th annual Google Code-in (GCI) which, like last year, was bigger and better than ever. Mentors from each of the 17 organizations are busy reviewing the last of the work submitted by student participants.

Each organization will pick two Grand Prize Winners who will receive a trip to Google’s Northern California headquarters this summer where they will meet Google engineers, see exciting demos and presentations and enjoy a day of adventure in San Francisco. You can learn about the experiences of the 2015 Grand Prize Winners in our short series of wrap-up blog posts. We’ll announce the new Grand Prize Winners and the Finalists here on January 30.

We would like to congratulate all of the new and returning students who participated this year. We’re thrilled with the turnout: over the last seven weeks, 1,374* students from 62 countries completed 6,397* tasks in the contest.

And a HUGE thanks to the people who are the heart of our program: the mentors and organization administrators. These volunteers spend countless hours creating and reviewing hundreds of tasks. They teach the young students who participate in GCI about the many facets of open source development, from community standards and communicating across time zones to version control and testing. We couldn’t run this program without you!

By Josh Simmons, Open Source Programs Office

* These numbers will increase over the coming days as mentors review the final work submitted by students.

Dojo 2 updates – Week ending Jan, 13 2017

The Dojo Toolkit - Announcements - 9 hours 3 min ago

We’ve accomplished a lot on Dojo 2 over the past few months, which has meant a fair amount of churn and improvements. Rather than trying to recap everything, we’re going to start covering some of the highlights in more frequent, shorter blog posts than we did in 2016.

Dojo 2 roadmap update

We have a new Dojo 2 roadmap. It’s currently more accurate about the things we’ve finished than it is about the things that are upcoming. We’re in the process of splitting out the remaining items into things that block the first Dojo 2 beta, and those that will follow it.

Scoped packages

With npm, the first package to choose a name wins, and in the past this has led to things like dgrid, dstore, and even util and themes not being able to have the same name in npm as they do in our own repositories. npm does not make it easy to provide aliases between names, so there’s been a fair amount of workarounds needed to provide a consistent installation experience for npm and non-npm users.

A while back, npm added support for scoped packages, so that it would be easy enough to refer to something as @dojo/core rather than dojo-core. We had resisted going this route as we were still aiming to support bower, but with a significant decrease in adoption of bower, and a heavy reliance on npm for the Dojo 2 development approach, we’ve made the decision to drop bower support for Dojo 2 and we’ve started using scoped packages.

In your code, the main change will be with how you include and reference dependencies. A dojo/core commit shows how this works in practice, but the things to note are:

  • The source package remains in the same location, e.g. dojo/loader is still found at https://github.com/dojo/loader
  • When including that package as a dependency, you will now include it as @dojo/loader instead of dojo-loader in both your package.json as well as within any ES6 module import statements, as well as via any npm install commands, e.g. npm install @dojo/loader

Besides being able to keep short and consistent package names, all officially supported Dojo 2 packages will be included under this scope.

Introducing Draco: compression for 3D graphics

Google Open Source Blog - Fri, 01/13/2017 - 18:00
3D graphics are a fundamental part of many applications, including gaming, design and data visualization. As graphics processors and creation tools continue to improve, larger and more complex 3D models will become commonplace and help fuel new applications in immersive virtual reality (VR) and augmented reality (AR).  Because of this increased model complexity, storage and bandwidth requirements are forced to keep pace with the explosion of 3D data.

The Chrome Media team has created Draco, an open source compression library to improve the storage and transmission of 3D graphics. Draco can be used to compress meshes and point-cloud data. It also supports compressing points, connectivity information, texture coordinates, color information, normals and any other generic attributes associated with geometry.

With Draco, applications using 3D graphics can be significantly smaller without compromising visual fidelity. For users this means apps can now be downloaded faster, 3D graphics in the browser can load quicker, and VR and AR scenes can now be transmitted with a fraction of the bandwidth, rendered quickly and look fantastic.


Sample Draco compression ratios and encode/decode performance*
Transmitting 3D graphics for web-based applications is significantly faster using Draco’s JavaScript decoder, which can be tied to a 3D web viewer. The following video shows how efficient transmitting and decoding 3D objects in the browser can be - even over poor network connections.



Video and audio compression have shaped the internet over the past 10 years with streaming video and music on demand. With the emergence of VR and AR, on the web and on mobile (and the increasing proliferation of sensors like LIDAR) we will soon be swimming in a sea of geometric data. Compression technologies, like Draco, will play a critical role in ensuring these experiences are fast and accessible to anyone with an internet connection. More exciting developments are in store for Draco, including support for creating multiple levels of detail from a single model to further improve the speed of loading meshes.

We look forward to seeing what people do with Draco now that it's open source. Check out the code on GitHub and let us know what you think. Also available is a JavaScript decoder with examples on how to incorporate Draco into the three.js 3D viewer.

By Jamieson Brettle and Frank Galligan, Chrome Media Team

* Specifications: Tests ran with textures and positions quantized at 14-bit precision, normal vectors at 7-bit precision. Ran on a single-core of a 2013 MacBook Pro.  JavaScript decoded using Chrome 54 on Mac OS X.

Stereotype Checker

Date Created: Fri, 2017-01-13 04:03Date Updated: Fri, 2017-01-13 09:32NovaTec Consulting GmbHSubmitted by: CA ITA Novatec

The Stereotype Checker is an extension to checkstyle checking if your code matches the defined architecture.

More information can be found on the GitHub pages

If you don't check your architecture it doesn't exist in reality.

The architecture is a contract between developers (including the architect if one exists) of a project on how to structure a software. In a classical architecture there are many layers (e.g. UI, business, persistence) and the architecture defines which layer is allowed to talk to another layer. If you don't check this automatically, often this contract is not followed due to the reason that the developer does not get a fast or even any feedback that some changes break the contract.

How does the stereotype check help following the contract?

In a layered architecture often there are some classes that implement a special behavior like transformer, controllers or business functions. They are called stereotypes. Stereotypes belong to a specific layer. Stereotypes are defined by a combination of:

  • Postfix of the classname
  • Package of the class
  • Interface implemented by the class
  • Class extended by the class
  • Annotations the class has

The stereotype check tests if a class conforms to a configured stereotype and checks if the class has a dependency to an other stereotype class that is not allowed.

Dont’s When Dealing with New Contributors

SourceForge.net: Front page news - Fri, 01/13/2017 - 06:24

Open source projects are amazing in that practically anyone can come in and make a difference. But it can also be a burden for the exact same reason. Just ask project developers and maintainers.

If you have been or currently are a project developer or maintainer, this scenario may be familiar to you: you’re juggling a million things with your project and out of nowhere an external contribution comes in. You’re grateful of course, but you’re also sighing inside and thinking, great. More work for you. And you wouldn’t be wrong.

New contributions can come with a lot of work: reviewing patches and reworking code among others. But thinking of them in this negative way can lead to some bad decisions– decisions that can make open source projects a little less open and a lot more unwelcoming, sometimes even hostile. This is the one big mistake you do not want to be making.

New contributions help keep open source projects going. Developers should really avoid thinking negatively of them as this can lead to actions that keep new contributors away.

Purposefully Discouraging New Contributions

Unfortunately for some, this negativity and the bad practices that result from it can come instinctively or unknowingly simply to avoid “added” work. They’ll say they don’t want contributions; make it difficult for newcomers to make contributions; or purposefully make new contributors feel unwelcome.

The first thing that developers have to realize here is that doing these discouraging things will only hurt instead of help their project. They’re missing out on additional support that can only be beneficial to their project. They could be preventing the entry of a future maintainer. The second thing they need to realize is that these contributions are not really “added” work but work that is essentially part of every open source project. It may not always be the most important part, but it is still part of the project and of the open source process in general, so it should not be discouraged.

Blind to Bad Habits

Even if you don’t do things to purposefully discourage new contributors, there may be other things you’ve gotten used to doing that you didn’t know or notice are actually discouraging. For example: handing new contributors grunt work. It’s often instinctual for maintainers to hand these jobs off to newbies, and in many cases, it’s fine. However, this is not true for all. Some contributors have different motivations and expectations; others are more skilled than they let on. By simply handing them grunt work without consulting them, slowly but surely they will be discouraged to continue with the project.

Conversely, some maintainers expect newcomers to already know the ins and outs of the project, and ask too much of them too soon. This results in the newcomer feeling incompetent.

In these cases, it’s important for project developers and maintainers to properly assess the ability and expectations of newcomers and assign tasks appropriately. You can start by asking them to send in some patches, and review these patches. Simply communicating with them could even be enough to gauge where a new contributor would prove to be most useful within a project. By doing these things, newcomers will feel more fulfilled and be more likely to stick around and help, and the project will be able to benefit from maximizing the newcomer’s skills.

JanusGraph connects the past and future of Titan

Google Open Source Blog - Thu, 01/12/2017 - 19:04
We are thrilled to collaborate with a group of individuals and companies, including Expero, GRAKN.AI, Hortonworks and IBM, in launching a new project — JanusGraph — under The Linux Foundation to advance the state-of-the-art in distributed graph computation.



JanusGraph is a fork of the popular open source project Titan, originally released in 2012 by Aurelius, and subsequently acquired by DataStax. Titan has been widely adopted for large-scale distributed graph computation and many users have contributed to its ongoing development, which has slowed down as of late: there have been no Titan releases since the 1.0 release in September 2015, and the repository has seen no updates since June 2016.

This new project will reinvigorate development of the distributed graph system to add new functionality, improve performance and scalability, and maintain a variety of storage backends.

The name "Janus" comes from the name of a Roman god who looks simultaneously into the past to the Titans (divine beings from Greek mythology) as well as into the future.

All are welcome to participate in the JanusGraph project, whether by contributing features or bug fixes, filing feature requests and bugs, improving the documentation or helping shape the product roadmap through feature requests and use cases.

Get involved by taking a look at our website and browse the code on GitHub.

We look forward to hearing from you!
