iPOJO Nature

iPOJO Nature provides a JDT compilation participant to manipulate iPOJO components at compile time.

This plugin simplifies the development of iPOJO Components in Eclipse:

  • It provides the annotation JAR as an Eclipse library: not need to use a fixed path to the JAR file
  • It manipulates the classes as soon as they are compiled: you can use iPOJO components directly in your Run Configurations, without any special operation

This plugin has been tested on Eclipse Kepler and Luna.

EMF Forms

EMF Forms provides a new way of developing form-based UIs. Instead of manually coding form-based layouts, it allows you to describe the UI with a simple model instead of with code. The approach allows you to more efficiently produce and iteratively refine form-based UIs that conform to a uniform look and feel. EMF Forms also lowers the technical entry barrier to creating form-based UIs. The UI description is interpreted by a rendering engine and allows you to switch between the UI technology stack to Swing, SWT, JavaFX or Web just by replacing the renderer.

Cayley: graphs in Go

Google Open Source Blog - Wed, 06/25/2014 - 19:45

Four years ago this July, Google acquired Metaweb, bringing Freebase and linked open data to Google. It’s been astounding to watch the growth of the Knowledge Graph and how it has improved Google search to delight users every day.

When I moved to New York last year, I saw just how far the concepts of Freebase and its data had spread through Google’s worldwide offices. I began to wonder how the concepts would advance if developers everywhere could work with similar tools. However, there wasn’t a graph available that was fast, free, and easy to get started working with.

With the Freebase data already public and universally accessible, it was time to make it useful, and that meant writing some code as a side project.

So today we are excited to release Cayley, an open source graph database.

Cayley is a spiritual successor to graphd; it shares a similar query strategy for speed. While not an exact replica of it’s predecessor, it brings it’s own features to the table:
• Multiple (modular) backend stores, such as LevelDB and MongoDB
• Multiple (modular) query languages
• Easy to get started
• Simple to build on top of as a library
and of course
• Open Source

Cayley is written in Go, which was a natural choice. As a backend service that depends upon speed and concurrent access, Go seemed like a good fit. Go did not disappoint; with a fantastic standard library and easy access to open source libraries from the community, the necessary building blocks were already there. Combined with Go’s effective concurrency patterns compared to C, creating a performance-competitive successor to graphd became a reality.

To get a sense of Cayley, check out the I/O Bytes video we created where we “Build A Small Knowledge Graph”. The video includes a quick introduction to graph stores as well as an example of processing Freebase and linked data.

You can also check out the demo dataset in a live instance running on Google App Engine. It’s running with the sample dataset in the repository — 30,000 movies and their actors, roles, and directors using Freebase film schema. For a more-than-trivial query, try running the following code, both as a query and as a visualization; what you’ll see is the neighborhood of the given actor and how the actors who co-star with that actor interact with each other:
costar = g.M().In("/film/performance/actor").In("/film/film/starring")

function getCostars(x) {  return g.V(x).As("source").In("name")          .Follow(costar).FollowR(costar)          .Out("name").As("target")}

function getActorNeighborhood(primary_actor) {  actors = getCostars(primary_actor).TagArray()  seen = {}  for (a in actors) {    g.Emit(actors[a])    seen[actors[a].target] = true  }  seen[primary_actor] = false  actor_list = []  for (actor in seen) {    if (seen[actor]) {      actor_list.push(actor)    }  }  getCostars(actor_list).Intersect(g.V(actor_list)).ForEach(function(d)
{    if (d.source < {      g.Emit(d)    }  })}
getActorNeighborhood("Humphrey Bogart")To get involved, check out the project on GitHub and join the mailing list. But most importantly, have fun building your own graphs!

Google Summer of Code 2014 New Organizations - Part One

Google Open Source Blog - Mon, 06/23/2014 - 23:40
Every year, we spend time highlighting each of the “rookie” organizations who have joined Google Summer of Code (GSoC). With over 40 new organizations to the program in 2014, we’ll dedicate Fridays this summer to spotlight their mission and goals of participating in GSoC. This week, the Organization Administrators from Amahi and Code Mirror tell us more about their organizations.
Amahi is an open source home server solution based on linux distribution, developed with the goal of making networking simple. It provides all the functionality you would want in a home server (e.g. DHCP, DNS, File Sharing), while being as easy to use as a web browser. Designed as a modular architecture, Amahi is easily expandable through one click application installs to provide additional features such as Media Streaming, VPN, Disk Pooling and more.

This is Amahi’s first year as a mentoring organization in Google Summer of Code and we were
fortunate to have three student participants. Kasun Thennakoon will work on a Disk Wizard plugin which is one of the most requested features on the platform side. This will provide an intuitive interface for adding new storage to your home server. Arpit Goyal will work on “what is next”, by upgrading the platform to the latest technology (i.e. Rails 4) and facilitate the application installation by improving the Amahi plugin system. Last but not least, we have Artur Dryomov who will work on the Amahi Anywhere android app, that will give users access to their home server data from any location without VPN or port forwarding.

By Carlos Puchol and Bogdan Mitrea, Amahi Organization Administrators

CodeMirror is a versatile text editor implemented in JavaScript for your browser. It is specialized for editing code and comes with a number of language modes and add-ons that implement more advanced editing functionality. A rich programming API and a CSS theming system are available for customizing CodeMirror to fit your application. We've had a pretty narrow developer base thus far—participating in Google Summer of Code is a great way for us to get some talent on board for the summer, and hopefully longer.

This summer we have two Google Summer of Code students. One who is working on improving bidirectional text support and the other student will work on improving the vim bindings (specifically the visual mode and undo tree).

Google Summer of Code 2014 midterms are here!

Google Open Source Blog - Mon, 06/23/2014 - 20:30
This week marks the halfway point of Google Summer of Code 2014. Both students and mentors will be submitting their midterm evaluations of one another through Friday, June 27 as indicated in our timeline. If you would like to read more about these midterm evaluations, please check out the "How Do Evaluations Work?" link on our FAQ.

The next milestone for the program will be the “pencils down” date of August 11 after which students can take a week to scrub their code, write tests, improve calculations and generally polish their work before the firm end of coding on August 18.

There has been fantastic progress made so far, and we encourage all the students, mentors, and org admins to keep up the great work!

Google Summer of Code 2014 by the numbers: Part two

Google Open Source Blog - Wed, 06/18/2014 - 20:00
Our first “by the numbers” post was about what countries this year’s accepted Google Summer of Code students are from - all 73 countries - which made for a big list. This time we’re serving up a mix of interesting stats in smaller charts.

"How old are the students?"
Google Summer of Code is for students ages 18 and older - but note the lack of an upper limit. While most of the students are relatively young, we also welcome non-traditional students to participate. This year our oldest student is 57.

“Am I the only undergraduate in the program?”
Year after year the majority of GSoC students, more than 50%, are undergraduates, but Master and PhD programs are well represented also. 2014 is no exception.
"How many women are participating in GSoC 2014?"We are very pleased to report that just over 10% of this year’s accepted students are women. The percentage of female students has been increasing year over year since 2006, but this is the first time we’ve broken the 10% barrier.  We are obviously still a very long way from gender parity, but we’re glad this number continues to trend upward.

We will be doing additional posts about the statistics for GSoC 2014 in the next few weeks. If you have questions, please drop us a comment and we’ll do what we can to answer in an upcoming post.
