  • Can 3D Printing Really Solve PPE Shortage in COVID-19 Crisis? The Myth, and The Facts!

    Amid COVID-19 crisis, we see severe shortage of Personal Protective Equipment (PPE) worldwide, to the point that a strict organization like FDA is making exceptions for PPE usage, and there are volunteer effors to try to alleviate this shortage like GetUsPPE. Also, Centers for Disease Control and Prevention (CDC) provides an Excel spreadsheet file to help calculate the PPE Burn Rate.

    There are many blog posts, video tutorials, and guides that teach people how to print their face shields and masks.

  • Raspberry Pi won’t let your watched pot boil
  • Growing fresh veggies with Rpi and Mender

    Some time ago my wife and I decided to teach our kids how to grow plants. We both have experience as we were raised in small towns where it was common to own a piece of land where you could plant home-grown fresh veggies.

    The upbringing of our kids is very different compared to ours, and we realized we never showed our kids how to grow our own veggies. We wanted them to learn and to understand that “the vegetables do not grow on the shop-shelf”, and that there is work (and fun) involved to grow those.

    The fact that we are gone for most of the summer and to start our own garden just to see it die when we returned seemed to be pointless. This was a challenge. Luckily, me being a hands-on engineer I promised my wife to take care of it. There were two options: we could buy something that will water our plants when we are gone, or I could do it myself (with a little help from our kids). Obviously I chose the more fun solution…

  • Comfile Launches 15-inch Industrial Raspberry Pi Touch Panel PC Powered by RPi CM3 Module

    Three years ago, we noted Comfile has made 7-inch and 10.2-inch touch panel PC’s powered by Raspberry Pi 3 Compute Module. The company has recently introduced a new model with a very similar design except for a larger 15-inch touchscreen display with 1024×768 resolution.

    ComfilePi CPi-A150WR 15-inch industrial Raspberry Pi touch panel PC still features the CM3 module, and the same ports including Ethernet, USB ports, RS232, RS485, and I2C interfaces accessible via terminal blocks, and a 40-pin I/O header.

  • Joachim Breitner: Learn Haskell on CodeWorld writing Sokoban

    Two years ago, I held the CIS194 minicourse on Haskell at the University of Pennsylvania. In that installment of the course, I changed the first four weeks to teach the basics of Haskell using the online Haskell environment CodeWorld, and lead the students towards implementing the game Sokoban. As it is customary for CIS194, I put my lecture notes and exercises online, and this has been used as a learning resources by people from all over the world. But since I have left the University of Pennsylvania, I lost the ability to update the text, and as the CodeWorld API has evolved, some of the examples and exercises no longer work.

  • SiFive Begins Adding RISC-V "Bullet" Microarchitecture Code To LLVM

    On Friday night patches began to appear for "RISC-V Bullet" in the LLVM compiler code-base. The initial work is on the scheduler being added for the RISC-V Bullet. The initial scheduler is in place for the RISC-V Bullet microarchitecture and bullet-rv32 / bullet-rv64 naming.

  • Pho 1.0, Belated Release

    I was doing some disk housekeeping and noticed that my venerable image viewer, Pho, was at version 1.0pre1, and had been since 2017. It's had only very minimal changes since that time. I guess maybe it's been long enough that it's time to remove that -pre1 moniker, huh?

  • GammaRay 2.11.2

    We have released version 2.11.2 of our Qt application introspection tool GammaRay, bringing support for Qt 5.15 and improved Qt Quick item picking. GammaRay is a software introspection tool for Qt applications developed by KDAB. Leveraging the QObject introspection mechanism it allows you to observe and manipulate your application at runtime. This works both locally on your workstation and remotely on an embedded target.

  • A meta issue for modules: bug tracking

    I was reading a module on meta::cpan when I spied a small issue. I went up to the Issues link, clicked, and was sent to rt.cpan. I know that many module authors now have their modules on sites like GitHub, GitLab, or Bitbucket. Before I posted the issue on rt.cpan, I checked the author's profile for a linked account to one of the other sites. I found the module on GitHub and read the CONTRIBUTING.md to find the author does want issues reported there and not rt.cpan. I did not report my original issue, I reported the link issue instead as it seemed more important. Today is not the first time I noticed this issue with a module's bug tracking. Before continuing, I have not released a module to CPAN and am still learning all that goes into releasing one. Please be gentle if I am wrong or stating an obvious well known fact.

  • Gisle Aas's CPAN distributions are available for adoption

    Gisle Aas (GAAS on CPAN) is a well-known CPAN author, who made his first releases back in 1995. Over the years he has developed and maintained a number of keystone modules that most of us have relied on, whether we realised it or not. Gisle has informed the PAUSE admins that he will no longer be maintaining his CPAN distributions, and is open to responsible adoption. In this blog post we'll summarise what distributions are available, and our interpretation of responsible adoption. If you're interested, please read this post, and if you still would like to adopt a distribution, contact the PAUSE admins (modules at perl dot org) and not Gisle.

  • Firefox Nightly Flips On New JIT "Warp" Code For Greater JavaScript Performance

    Mozilla's SpiderMonkey JavaScript engine team have been working on a big update to their just-in-time compiler code. This big update called "Warp" is now enabled in the latest Firefox Nightly builds for offering big speed-ups. Warp aims to improve the Firefox JavaScript performance by reducing the amount of internal type information that is tracked along with other optimizations. Warp can lead to greater responsiveness and faster page load speed. Numbers cited by Warm developers are normally in the 5~15% range.
