A Beaglebone, a Blender, a Board, and a Swarm.

Hardware isn’t generally my thing. When it comes to software, I like to break and create. But in my opinion, hardware should just work. But even though that’s another story altogether, it did explain my apprehension when I greeted the UPS guy one morning delivering a BeagleBone Black.

Let’s begin with the BBB. It’s a computer the size of a credit card, which isn’t that impressive if you realise that your phone is a computer. I find the best way to explain it is in terms of two other products, the Arduino and the Raspberry Pi. The Arduino is a similarly sized (comes in multiple sizes though) controller where you can upload scripts, plug in a hardware circuit (wires and lightbulb, that sort of thing), and have it control the circuit. Despite its power in hardware control, it only has a small scripting interface for you to do your programming. The Raspberry Pi is the opposite. It’s a full Linux computer (based off Debian), but does not have proper hardware controls out of the box. The BBB provides the best of both worlds: a full Linux system (Angstrom Linux, but of course you can flash your own), and a ridiculous number of IO pins to control circuits. All this awesome power at 45USD.

The next step upon receiving this wonderboard was obvious. Let’s build a swarm of robots. Along with two university friends, Lawrence Huang and Gloria Nam, we set out planning the system.

Programming/Development: fwupd, LLVM and More

  • CSR devices now supported in fwupd
    The BlueCore CSR chips are used everywhere. If you have a “wireless” speaker or headphones that uses Bluetooth there is a high probability that it’s using a CSR chip inside. This makes the addition of CSR support into fwupd a big deal to access a lot of vendors. It’s a lot easier to say “just upload firmware” rather than “you have to write code” so I think it’s useful to have done this work.
  • Skylake Server Scheduler Model Updated In LLVM 6.0 Along With Other Intel CPU Updates
  • Most Software Code Will Be Written By Machines By 2040, Researchers Predict
    Imagine a scenario where a programmer needs to follow a couple of tried and tested procedures to write code that becomes a part of a bigger program that needs some insightful contribution from another programmer. So, is the first programmer really needed? Can’t we find a robotic replacement for the same? In the past, GitHub CEO had already made a prediction which says that future of coding is no coding at all. A similar speculation has been made by the researchers at the Oak Ridge National Laboratory, Tennessee, who have said that machines will write most of their own code by 2040.
  • Hazelcast joins Eclipse, JCache is key focal point
    Open source In-Memory Data Grid (IMDG) company Hazelcast has joined the Eclipse Foundation – and it has done so for a reason. Hazelcast’s primary focus will be on JCache the Eclipse MicroProfile and EE4J. In particular, Hazelcast will be collaborating with members to popularize JCache, a Java Specification Request (JSR-107). So what place does JCache fill in the universe then?

Software: Darktable, VLC, Mesa, Audacity, Toplip, GNUstep

  • Darktable 2.4-RC1 Rolls Out With Windows Support, OpenCL Improvements
    The open-source Darktable RAW photography software that's long been available for Linux and macOS has finally been ported to Microsoft Windows. But fortunately that's not all to be found in Darktable 2.4. While Windows support is their big headline feature of Darktable 2.4, the RC1 release that came out today is also packed with other improvements.
  • Linux Release Roundup: VLC, Mesa, Audacity + More
    Another week has flown by, making it time for another round-up of pertinent Linux app releases that didn’t manage to wangle a full post’s worth of waffle on this site. This week’s crop of curios includes updates to the world’s most popular open-source video player, the world’s most popular open-source audio editor, and the world’s most popular open-source graphics drivers.
  • Toplip – A Very Strong File Encryption And Decryption CLI Utility
    There are numerous file encryption tools available on the market to protect your files. We have already reviewed some encryption tools such as Cryptomater, Cryptkeeper, CryptGo, Cryptr, Tomb, and GnuPG etc. Today, we will be discussing yet another file encryption and decryption command line utility named “Toplip”. It is a free and open source encryption utility that uses a very strong encryption method called AES256, along with an XTS-AES design to safeguard your confidential data. Also, it uses Scrypt, a password-based key derivation function, to protect your passphrases against brute-force attacks.
  • GNUstep Takes Another Step Forward For Implementing Apple's Cocoa Frameworks
    GNUstep is the long-standing free software project working to implement Apple's Cocoa Objective-C frameworks used by macOS. The GNU project has made new releases of their GUI and Back libraries. GNUstep GUI 0.26 is out this morning as the latest update to their graphical user-interface library. GNUstep GUI 0.26 has a number of compatibility improvements, translation updates, mouse tracking logic improvements, bug fixes, and other work.
