ZuriHac 2014: Haskell hackathon in Zurich

Google Open Source Blog - Mon, 06/30/2014 - 22:30
The Google Open Source Programs Office recently co-sponsored a three-day hackathon for Haskell, an open source functional programming language. Johan Tibell from Google’s Zurich office talks more about the event below.

June 6th saw the third installment of ZuriHac, a three-day Haskell hackathon in Zurich, Switzerland. With roughly 100 attendees from all over the world, this was the biggest ZuriHac to date.

In addition to hacking, hallway discussions, a demo session, and impromptu talks on topic ranging from GHC hacking to category theory, there were two one-hour talks. Simon Marlow talked about haxl, a library for automatically parallelization and batching of data requests. Edward Kmett followed with a talk about new and exciting persistent data structures based on cache-oblivious algorithms.
edward-profunctor.JPGThe hacking was all over the map. An entire room was dedicated to teaching newcomers how to hack on GHC, the Haskell compiler. A smaller group of people worked on various improvements to Cabal (the Haskell build system) by improving the dependency solver and making sure that parallel package builds work well. More lighthearted projects included a remake of 1990s cult video game Stunts.

Google Summer of Code new organizations - Part two

Google Open Source Blog - Fri, 06/27/2014 - 18:00
We have two great new Google Summer of Code organizations to spotlight this week, OpenKeychain and Linaro.  It’s hard to believe that we are almost halfway through the coding period for GSoC 2014. Midterm evaluations for both mentors and students are due today, Friday, June 27.
openkeychain.pngOpenKeychain allows you to manage cryptographic keys and encrypt messages as well as files for your contacts on Android. Our project is focused on providing an easy user interface based on Android design principles. It implements the OpenPGP standard, often referred to as GPG or PGP, and enables a secure end-to-end communication in times of mass surveillance.

As a new organization to Google Summer of Code, we secured two student slots. One of our students will work on a better abstraction between cryptography backend and user interface code, resulting in some unit tests, while also working on a better integration of the OpenPGP web-of-trust. The other student will work on a better integration of OpenKeychain into the Android OS, including better support for file encryption and decryption using Android 4.4 features, integration with Android's contact application, and work on potential improvements for the API.

By Dominik Schürmann, OpenKeychain Organization Administrator


linaro-logo.pngLinaro is the place where engineers from the world's leading technology companies define the future of Linux on ARM. Linaro is a not-for-profit engineering organization with over 200 engineers consolidating and optimizing open source software for the ARM architecture in many areas.

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:
• RESTful API
• 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 Schema.org 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 < d.target) {      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!
