grpc »

grpc is high performance, open source, general-purpose RPC framework from Google.

gRPC is a modern, open source remote procedure call (RPC) framework that can run anywhere. It enables client and server applications to communicate transparently, and makes it easier to build connected systems.

The main usage scenarios:

  • Low latency, highly scalable, distributed systems.
  • Developing mobile clients which are communicating to a cloud server.
  • Designing a new protocol that needs to be accurate, efficient and language independent.
  • Layered design to enable extension eg. authentication, load balancing, logging and monitoring etc.

Torch–A Scientific Computing Framework »

Torch is a scientific computing framework with wide support for machine learning algorithms. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation.

A summary of core features:

  • a powerful N-dimensional array
  • lots of routines for indexing, slicing, transposing, …
  • amazing interface to C, via LuaJIT
  • linear algebra routines
  • neural network, and energy-based models
  • numeric optimization routines
  • Fast and efficient GPU support
  • Embeddable, with ports to iOS, Android and FPGA backends

The goal of Torch is to have maximum flexibility and speed in building your scientific algorithms while making the process extremely simple. Torch comes with a large ecosystem of community-driven packages in machine learning, computer vision, signal processing, parallel processing,image, video, audio and networking among others, and builds on top of the Lua community.

At the heart of Torch are the popular neural network and optimization libraries which are simple to use, while having maximum flexibility in implementing complex neural network topologies. You can build arbitrary graphs of neural networks, and parallelize them over CPUs and GPUs in an efficient manner.

Streaming Build System–gulp »

Gulp does nothing but provide some streams and a basic task system.

  • You use standard libraries to do things
  • Plugins are simple and do one thing – most are a ~20 line function
  • Tasks are executed with maximum concurrency
  • I/O works the way you pictur

    Glide–Android Media Management »

    Glide is a fast and efficient open source media management framework for Android that wraps media decoding, memory and disk caching, and resource pooling into a simple and easy to use interface.

    Glide supports fetching, decoding, and displaying video stills, images, and animated GIFs. Glide includes a flexible api that allows developers to plug in to almost any network stack. By default Glide uses a custom HttpUrlConnection based stack, but also includes utility libraries plug in to Google’s Volley project or Square’s OkHttp library instead.

    Glide’s primary focus is on making scrolling any kind of a list of images as smooth and fast as possible, but Glide is also effective for almost any case where you need to fetch, resize, and display a remote image.

    WebCommander–PowerShell Web Services »

    WebCommander wraps Powershell scripts into web services and presents them as a simple one-click automation solution. This can be likened to an "App Store" for PowerShell/PowerCLI !

    Wrapping a program as a web service means using a web portal to gather parameters and then passing them to the wrapped program. By doing so, details on how the program is developed and what underlying system it depends on become transparent to others. People could make easy use of the program via browser manually or through any programming language that supports calling web services.

    End users usually run many repeatable routines which could be automated by PowerCLI. WebCommander makes it even easier by providing a more user friendly UI and result report. Users have no need to setup their own environment to use PowerCLI, keep upgrading it, download and learn scripts written by others.

    Open Source Home Automation »

    More and more new cool devices and technologies arrive at our homes every day. But though they are all aimed at enhancing our lifestyle they all lack one important feature: a common language they could speak to each other to create a really automated and smart environment at home. The main goal of openHAB is to provide an integration platform to fix this issue.

    openHAB is a software for integrating different home automation systems and technologies into one single solution that allows over-arching automation rules and that offers uniform user interfaces.

    This means openHAB
    1. is designed to be absolutely vendor-neutral as well as hardware/protocol-agnostic
    2. can run on any device that is capable of running a JVM (Linux, Mac, Windows)
    3. lets you integrate an abundance of different home automation technologies into one
    4. has a powerful rule engine to fulfill all your automation needs
    5. comes with different web-based UIs as well as native UIs for iOS and Android
    6. is fully open source
    7. is maintained by a passionate and growing community
    8. is easily extensible to integrate with new systems and devices
    9. provides APIs for being integrated in other systems

    Open Source Graph Database–Cayley »

     

    image

    Cayley is an open-source graph inspired by the graph database behind Freebase and Google’s Knowledge Graph.

    Its goal is to be a part of the developer’s toolbox where Linked Data and graph-shaped data (semantic webs, social networks, etc) in general are concerned.

    • Written in Go
    • Easy to get running (3 or 4 commands, below)
    • RESTful API
      • or a REPL if you prefer
    • Built-in query editor and visualizer
    • Multiple query languages:
      • JavaScript, with a Gremlin-inspired* graph object.
      • (simplified) MQL, for Freebase fans
    • Plays well with multiple backend stores:
    • Modular design; easy to extend with new languages and backends
    • Good test coverage
    • Speed, where possible.

    Rough performance testing shows that, on consumer hardware and an average disk, 134m triples in LevelDB is no problem and a multi-hop intersection query — films starring X and Y — takes ~150ms.
