ejolson I think you were right the first time. Firefox armhf is not supported on Stretch and has been broken since 55 or earlier. Here's the ticket where they say it's a tier-3 platform and might fix it someday. I just installed firefox-esr (60.3) on Debian and got the usual startup crash. Earlier t...

Re: 64-bit operating system

There is still the problem (when it comes to only officially supporting one image at a time) that there is no 64-bit capable Pi0/Pi0W anywhere in sight. ...

Re: Teaching Python with Minecraft in a classroom with Pi's and PC's

One option is to run the full-fledged Java Edition on each Pi 3B+, then you'd have no trouble sharing the world among Pi and PC users. The drawbacks: * Requires version 1.12 or older * Pi students would need to keep their game windows small to ensure systems remain responsive for Python coding * Not...

The Pi 3B+ running in 32-bit compatibility mode completes the computation in 15.43 seconds. Based on rescaling the clock speeds of a different ARM-based single-board computer, it was estimated that the Pi 3B+ running in 64-bit mode should complete this same computation in only 7.49 seconds.

Great analysis on everything, jamesh! I like the point that vector fonts actually save RAM. I've got another tip for those looking to run aarch64 software on Raspbian or any 32-bit Pi OS.

Wine PPAs for Raspbian?

I built Wine 3.9 from source, but I'd like to try out various other versions. Building from source probably isn't the ...

Re: Compiling Error JFSW, Shadow Warrior port

It turns out SDL2 (main repo, not a fork) can be compiled with --enable-video-rpi while disabling the other video modes. That's enough for games like Duke Nukem to launch without a DISPLAY variable set. However, unlike eduke32, jfsw does not readily build with OpenGL disabled. From what I can tell J...

please be aware that I won't be able to provide a new kernel for EVERY single Raspbian kernel release. That's probably fine going forward. The real problem here appears to be that you distributed your custom kernel without its modules. Perhaps you could package those up before building a new one. (...
