In recent years there has been a surge in popularity of Chevrolet vehicles like the Chevrolet Bolt and, coming soon, the Equinox EV. There has also been increased popularity for Linux phones like the Librem phone, but unfortunately there has been no equivalent for the “myChevrolet” app for your own computer or Linux-phone… unless you know where to look.Continue reading “NodeRed for Onstar access for GM/Chevy vehicle access”
Next week the KNIME fall conference will be happening, Nov 14-16. For mathematicians or anyone wanting to look at some useful AI/Machine learning tools, this should be an informative conference! I’ve seen some previous sessions with interesting demos and overviews of new features they add to this open-source tool. Virtual passes are free to the live-streamed event! If it is like past online lessons, it is likely they will also be available later from their Youtube channel page.
You may know of grid squares for general location in a ham radio contest, or the What3Words system with its easy access if you have network access, but there is another often-used location project you may not have heard of which is also easier than sharing a long latitude and longitude number!Continue reading “Plus codes as an easy location-sharing option”
It’s that time of year again, with leaves falling, people getting in from the cold and wind and getting in to coding… Hacktoberfest is just a few days away!Continue reading “Hacktoberfest is coming up”
Many mathematicians enjoy puzzles – and digging in to interesting code. Simon’s Puzzle collection is an open source collection of puzzles that any mathematician would enjoy:Continue reading “Puzzles – an open-source collection”
In a previous howto I showed how to build a .deb installer file for a Python program. This would work for the majority of systems with Debian/Ubuntu/Linux Mint etc. However there are many users on Arch Linux or Manjaro, which do not take this .deb installer file. Some Linux computers such as the popular (and currently out of stock 🙁 ) Pinebook laptop, and Pinephone come with Manjaro Linux, which takes Arch packages. Thankfully there is an easy way to add a package to the AUR for these Arch-based devices.Continue reading “Packaging a Python application for ArchLinux/Manjaro Linux”
If you have been maintaining a Python program that has been growing for some time with new features you may notice at some point it can get a bit lagging and slow. For example, the app that is powered by hearham.com repeaters listing has grown from thousands of repeaters to now over 10,000 repeaters in the listing shown in the app. This hung things up especially on devices like Raspberry Pi or Librem phone while starting up the app.Continue reading “Optimizing a Python program with profiling data”
One thing many don’t consider when setting up a GTK+ window application is that the same code that runs on a Linux phone or Linux computer, can also run on MS Windows with the same libraries! Next time you are on a Windows system and trying to set up a command or tool normally working on Linux, try this:Continue reading “Linux tools on Windows with MSYS2 (And a Repeater app for Windows!)”
