    node.js for BUG 2.0

    It was interesting to see the new Beagleboard "bone" project announcement today.  Particularly because of some software that ships with it; a browser-based development environment targeting the JavaScript language.  Given the popularity of the JavaScript language and a completely hosted environment, I can see how this is a great way to remove a lot of the annoying and error-prone steps to getting started with embedded development.  

    As a first step to see how this vision could be executed on BUG, I built Node.js and it's dependencies for BUG 2.0 and prepared a simple installer script.  Unzip the tarball on your BUG and run install.sh.  From there you can run the 'hello world' program also included to verify it's working.

    Java 7 (OpenJDK/IcedTea) for the BUG 2.0

    For anyone interested in Java 7, I have built OpenJDK 7 (via IcedTea) for BUG 2.0 (Angstrom, armv7, Zero VM).  The binaries are available here.  The binaries are not provided as Angstrom opkgs, so the installation process is manual. This is because it was built natively on a BUG, rather than using the OpenEmbedded cross compiling build system.  You'll also need to install libcups2 via opkg if you want to replace the Java 6 JRE to run BUG applications.  Here is my installation steps, assuming the j2re-image tarball is decompressed in /home/root:

     


    $ mkdir -p /usr/lib/jvm/java-7-openjdk/jre
    $ mv ~/j2re-image/* /usr/lib/jvm/java-7-openjdk/jre
    $ rm /usr/bin/java
    $ ln -s /usr/lib/jvm/java-7-openjdk/jre/bin/java /usr/bin/java
    $ opkg install libcups2

    Now if you restart Felix (via Knapsack if you are running a 3.0 release), you'll notice that the JVM running is java.runtime.version = 1.7.0_147-icedtea-b147 via http://bug/support.html.  This is provided on an experimental basis and I would not be surprised if problems pop up!

    An interesting benefit that IcedTea 7 provides (other than ARM compatibility via Zero) is alternative VM implementations CACAO and JamVM.  The binary build I have provided unfortunately does not include these but I'm going to try and build them.  Hopefully I can get Zero, Shark, CACAO, and JamVM all happily living inside the BUG!  :)

    Special thanks to xranby@irc.oftc.net#openjdk for his invaluable assistance!

    Support the Open Hardware Summit!

    Sponsor the Summit!

    Sponsorship for the Open Hardware Summit is open! Special thanks to our sponsors who have already donated.

    The summit is in its second iteration in partnership with MAKE and Makerfaire at the New York Hall of Science. Last year, 350 people came together to share knowledge about bringing open hardware to market, solving issues around open design, protocols and licensing. Many more people watched online and got involved in the conversation through the forums and twitter. Together with support from you, we have gained more momentum as a team. The definition we signed last year was turned into a license by CERN. We held a logo competition which received 129 submissions and chose one by popular vote. The summit continues to be about the DIY, Maker, small scale (and growing to large) fabrication movements and Open Hardware, and legalese around open source hardware.

    By sponsoring the Open Hardware Summit you’ll be fostering the open source hardware movement. Read more about Why to Sponsor.

    Open Hardware Summit 2011 - Call for Submissions

    * * * Please Redistribute * * *

    The Open Hardware Summit (OHS) invites submissions for the second annual summit, to be held on September 15, 2011 in New York City. The Open Hardware Summit is a venue to present, discuss, and learn about open hardware of all kinds. The summit examines open hardware and its relation to other issues, such as software, design, business, and law. We are seeking submissions for talks, breakout sessions, and demos from individuals and groups working with open hardware and related areas. Submissions are due by June 24, 2011. Notification of accepted proposals will happen by August 1st.

    Since the first Open Hardware Summit in 2010, we have seen the open hardware movement continue to flourish. The Open-Source Hardware Definition was announced, the OSHW logo was selected by a popular vote, an open source oil spill cleaning robot got more than $33,000 in crowd funding, Google adopted the open hardware movement’s biggest success story, Arduino, as its platform and our very own keynote speaker, Limor Fried, was featured on the front page of Wired Magazine – to name a few. Needless to say, open hardware is getting BIG.

    Submission topics

    Topics of interest for the summit include, but are not limited to:

    • Lessons learned from past projects
    • Legal and intellectual property implications of open-source hardware
    • Means of supporting collaboration and community interaction
    • Manufacturing
    • Distributed development and its relationship to physical goods
    • Digital fabrication (e.g. laser cutters and 3D printers)
    • Software design tools (CAD / CAM)
    • DIY technology
    • Ways to share information about hardware that’s not captured in source files
    • Business models
    • Manufacturing on demand
    • Competition and collaboration
    • Sustainability of open hardware products (e.g. how to unmake things)
    • Industrial design
    • “open-washing” (green washing for open source)
    • Open-hardware in the enterprise
    • Specific product domains: e.g. science, agriculture, communications, medicine

    And any other topic you think relates to openness and hardware. We want to hear all about it!

    Talk

    • Expected duration for talks is between 5 and 20 minutes, depending on the number and quality of submissions.
    • We expect all talks to be plenary (i.e. presented to the entire summit audience).
    • Talk submissions primarily containing marketing for a product will not be accepted. However, talks that share knowledge and insight derived from work on commercial products are welcome.

    Breakout session

    • Depending on submissions, there may be an opportunity to organize breakout sessions with smaller groups (5-40) to discuss a particular topic
    • We expect breakout sessions to occur during a single time-slot of approximately 1 to 2 hours.
    • Breakout session submissions should include an overview of the content and plan for the session.
    • You are encouraged to co-author breakout session submissions with other interested parties but sessions will be open to general summit attendees.

    BUG Software R2.1.0 (based on linaro 2.6.35) now available

    Greetings BUGgers!

    TL;DR: http://wiki.buglabs.net/index.php/Changelog_2.1.0

    Release R2.1.0 is available for download.  This is a major release, utilizing a new kernel and networking API, intended for general customer use with BUGbase YT (2.0) hardware.  

    The build artifacts can be found at:

     

    and

    Processing & BUG

    While using processing on ARM (via openjdk-6-zero) has been done for quite some time, (even using the Arduino IDE), we just got it working on BUG.

    Just running sketches couldn't be easier.  Processing 1.5.1 allows sketches to be exported as applications:

    created on: 06/01/11

    After hitting that, you should see the Sketch's jar in tie .pde's directory.  scp that up to bug using your favorite scp client, and just:

    java -jar Sketch.jar.

    Here's the pointillism example (in processing-1.5.1/modes/java/examples/Basics/Image/Pointillism/):

    created on: 06/01/11

    Running the IDE on BUG is pretty easy too, though I'm not sure why you'd want to...

    just:


    opkg update; opkg install openjdk-6-jdk
    wget http://processing.googlecode.com/files/processing-1.5.1-linux.tgz
    tar xzvf processing-1.5.1-linux.tgz
    cd processing-1.5.1
    rm -fr java
    ln -s /usr/lib/jvm/java-6-openjdk/ java

    After that, just ./processing and close the dialog regarding openjdk-6.  I'd suggest using it with our video module, as 320x240 isn't ideal for writing processing sketches ;D

    Solution Sprint #1 - BUGtunes

    The Challenge: Use BUG in a
    meaningful way... today

     

    The Proposal: Make BUG a
    wireless music server everyone can collaboratively add music to,
    create playlists with, and use.

     

    First: We white board the
    idea, add in possible functionality, then sketch the concept.

    Ideas:

    1. Use Jack Server

    2. BUGmpd connect to JACK

    3. Hook up the Traffic
      Light in a meaningful way

    4. Bot Bundle “Gong”
      Functionality

     

    So now we have a quick
    outline of what we want to do. Port JACK (http://jackaudio.org/)
    to the BUG, and have that BUG control the music we listen to.

    created on: 05/06/11

    created on: 05/06/11

     

     

     

     

    The Hardware:

    1 BUGbase 2.0

    1 BUGstinger

    1 BUGvonhippel

    1 Ethernet cable (may be
    over WiFi later, but for now, ethernet is more reliable)

    1 Pair of Speakers

    1 Rusty old computer (To
    hold the music – move to cloud services later?)

    1 Traffic Light

     

    Step 1. Tinker:

    created on: 05/06/11

    First, Andrew Turley writes
    his wish list, then he clutters it with junk

     

    Step 2: Prototype the
    Traffic lights:

    created on: 05/06/11

    Andrew Tergis and Jonathan
    Dahan discuss the intricacies of controlling a traffic light with the
    BUG. What should the light do? Where should it be placed? How do we
    Future Proof it?

     

    For now, the traffic light
    will give Buggers some visual feedback of the popularity of the song
    currently playing. Green means no one hates it, Yellow means it has
    been tagged as annoying, Red means GONG, and the song is banned from
    the playlist for the next week or so.

     

    Step 3: Get to work:

    created on: 05/06/11

    CODE! JONATHAN! CODE!
    FASTER!!!

     

     

    Step 4: Hook up the parts:

    created on: 05/06/11

    Plug it in Turley! You can
    do it! What a sweet looking Ethernet cable.

     

     

     

    Step 5: Turn it on:

    created on: 05/06/11

    Pretty Lights!

     

     

    Step 6: Make it go!

    created on: 05/06/11

    OK, so it isn't beautiful,
    yet, and we don't have the traffic light set up, yet, and it's pretty
    obvious it isn't wireless, yet... but it works!

     

     

                                                                                 The Software:

     

    jackaudio.org

    alsa-project.org

    http://bugmpd.local/relaxx/index.php

     

    We used relaxx as our Music
    Player Deamon, which makes it act like a regular MP3 player, except
    this one is usable from the web. Now all employees can send their
    music to the server, add songs to the playlist, and even skip the bad
    songs that our Sales Engineer plays. Yes, we are sick of “Where
    Brooklyn At?” Vish, but thanks for playing.

     

    The Future:

    Well we gave ourselves a day
    to complete the project. We now have music playing from the BUG, and
    the traffic light is working, but we don't have the IRC bot set up to
    “Gong” and switch songs yet. I have been advised that this is a
    small fix that will occur next Friday before we start Solution Sprint
    #2: The Rise of MotherBug 2.

    Check out the lights!

    created on: 05/06/11

     

    Nice work team :-)

    Here is a little more about how we actually did it:

    http://wiki.buglabs.net/index.php/Solution_Sprint_1_--_BUGTunes

     

    Friday fun-days are proving
    fruitful. What would YOU do with a BUG and a day?

    New software for an old BUG

    created on: 05/04/11While the BUG 2.0 hardware platform is the shiney new toy everyone wants/NEEEDS, what can we say about our trusty BUG 1.x devices sitting around?  I think they are in need of some love, and as a community effort, have released some alpha-level builds of BUG 2.0 software for BUG 1.x hardware.  The project is called leafcutter, and the idea is that your BUG 1.3 device should be able to run all the BUGapps that your 2.0 device does, assuming you have the necessary modules.  The main work involved in this is migrating from the legacy Poky 3.0 build system to the OpenEmbedded 2011-stable build system.  The result of this migration means:

    • Up to date packages
    • A "living" distro, where contributors are adding packages all the time
    • OSGi R4 implementation (Apache Felix)
    • OpenJDK (Java 1.6)

    I'm planning on having Dragonfly SDK support available, so development is seemless between hardware versions.  Have a look at the project page to see the current state of things.  Since this is not an official Bug Labs project, the sources are being hosted at Gitorious instead of the Bug Labs GitHub repo.  While the project is in an early stage, the basic Linux environment and OpenJDK JVM are currently working.  Depending on your needs, this may already be enough for some users to migrate.

    And as a community-hosted project, everyone is welcome to contribute!  Areas that need attention:

    • Abstracting and isolating BUG 2.0 HW APIs from 1.3 HW APIs in the OSGi layer
    • Fixing and enhancing the windowing system
    • Providing an 'extras' package repository
    • Testing kernel and module support
    • Testing existing BUGapps on BUG 1.3 hardware

    The start page has all the details regarding building and getting access to ready-to-install binaries.

    Open Source head to head

    created on: 05/01/11As part of research and development (aka R&D to those in the industry) I ordered an Ultimate Beagle Gadget Pack from our friends over at Liquidware.  As one of the new wave of Bug-gneers that joined this winter/spring, I want to get a good understanding of our friends and competitors in the embedded Linux world.  Of course, as an open source company many of our friends our our competitors, which is really cool. It's Especially cool when you can inspire new ideas across company, team, and international borders.

    I'd rant about 'marginal cost of software', Syndicalism, and Eben Moglen here but I better not.  I think  folks are here for the hardware, not for the hobby armchair economic and philosophy. People are here for open source development,  for quality hardware/software platform, and for the creative new ideas Bug dreams up. 

    In the spirit of the second, this is the opening post of 'Open Source Head to Head' series.  It will be a sporatic series, coming ont when I have time and a new toy, where I'll be comparing Bug Labs products with those of our friends, competitors, and collaborators.  This will include projects and products we use in development, competing products, and contrasting approaches to design.

    I'm calling these 'Head to Head' because both meanings of that apply to Open Source development.  As a solutions company we are competing on an open market.  We aim to have the best ideas, and to make the best platform for  our customers to build on top of.  However at the exact same time, we are constantly sharing ideas with the entire world at the speed of our own innovation. And we, in return, and getting great ideas shared back as quickly as we put them out. I think that is a powerful combination of incentives, and a fantatic model for driving innovation for our company, and for the whole human race.

    It almost goes without saying that I'm going to give the fairest assessment I can. Not only because it's the right thing to do, but because as developers and engineers we learn from our mistakes and shortcomings. Being honest and clear about that is good for science, and good for customers.  But  of course as a Bug-gineer, I'm may be a little tiny bit bias'd (Bug Rules!) in my review despite my best effort to be neural.
