Programming Leftovers and HowTos

  • Gitops Days - Day 2 playlist
  • Fast data modeling with JavaScript

    As a backend developer at the Railwaymen, a software house in Kraków, Poland, some of my tasks rely on models that manipulate and customize data retrieved from a database. When I wanted to improve my skills in frontend frameworks, I chose Vue, and I thought it would be good to have a similar way to model data in a store. I started with some libraries that I found through NPM, but they offered many more features than I needed.

  • The Death Of Corporate Research Labs

    As someone with many friends who worked at the legendary corporate research labs of the past, including Bell Labs and Xerox PARC, and who myself worked at Sun Microsystems' research lab, this is personal. Below the fold I add my 2c-worth to Arora et al's extraordinarily interesting article.

  • Debian welcomes the 2020 GSOC interns

    We are very excited to announce that Debian has selected nine interns to work under mentorship on a variety of projects with us during the Google Summer of Code.

    Here are the list of the projects, students, and details of the tasks to be performed.

  • 15 years

    With more than 500 millions od download, more than 30 mirrors in the world, my "little" repository, created 15 years ago, have became (I think) one of the reference pour PHP and RPM users, providing

    7 versions of PHP
    from 5.6 to 7.1 with security backports
    from 7.2 to 7.4
    8.0.0-dev
    150 extensions
    6 distributions
    RHEL / CentOS 6, 7 and 8
    Fedora 30 to 32
    3 distribution modes
    Base packages, 1 repository per version
    Software Collections for parallel installation
    Modules

  • Postel's law in development

    The robustness principle doesn’t necessarily result in robust software. I made one change to increase compatibility (good) but that allowed another fault to be introduced reducing compatibility (bad).

  • Curl file download on Linux
  • Steve Kemp: Updated my linux-security-modules for the Linux kernel
  • Why wait for Linux Mint Ulyana rather then install Cinnamon Desktop on native Ubuntu 20.04 ?

  • Talk Python to Me: #272 No IoT things in hand? Simulate them with Device Simulator Express [Roy: "Talk Python to Me" appears to be boosting Microsoft monopolists and proprietary software again]

    Python is one of the primary languages for IoT devices. With runtimes such as CircuitPython and MicroPython, they are ideal for the really small IoT chips. Maybe you've heard of the Circuit Playground Express, BBC micro:bit, or the fancy Adafruit CLUE. They aren't too expensive (ranging from $25 to $50 each). But for large groups such as classrooms, this can be a lot of money. Moreover, getting your hands on these devices can sometimes be tricky as well.

Olimex Tukhla High-End Open Source Hardware NXP i.MX 8QuadMax SBC in the Works

Most open-source hardware Arm Linux SBCs are optimized for cost, and there are few higher-end boards with extensive connectivity designed for professionals. Beagleboard X15 would be one of the rare examples currently available on the market, but it was launched five years ago. One European company noticed the void in this market and asked Olimex to develop a high-end open-source Linux board with a well-documented processor. They ruled out RK3399, and instead went Olimex Tukhla SBC will be powered by NXP i.MX 8QuadMax, the top processor of i.MX 8 family with two Cortex-A72 cores, four Cortex-A53 cores, and two real-time Cortex-M4F cores.

Robotics Recap: Learning, Programming & Snapping ROS 2

Robotics@Canonical puts a strong focus on the migration from ROS to ROS 2. ROS 2 benefits from many improvements, especially robot security. Our goal is to make it easy for you to transition to ROS 2, whether you’re completely new to ROS or a seasoned engineer retooling for a new environment. Your new platform should be secure-by-default, and we expect you’ll need to pivot between different environments as you migrate from ROS to ROS 2. Along the way we’ve encountered some friction points, some mild surprises, and some opportunities to better leverage existing tools. Whenever that happened we tried to fix them and share our experiences so you didn’t run into the same problems! This has resulted in blog posts and videos in three key focus areas: getting started with ROS 2, software development in ROS 2, and building snaps for ROS. Let’s recap some of our recent output.
