  • it’s used to verify that OpenGL ES2 works on your system. It’s the variant of 3D graphics drivers that is used on smartphones. Many apps nowadays write their GFX frontend with GLES2 so it uses the same code on phones and PCs, and if they compile the app to run in the web browser, WebGL is also based on GLES2.





  • It doesn’t matter for most drugs, as long as you can tolerate the taste. There is a gastric ulcers medicine that’s basically a weapons-grade concentrate of chili pepper, eating it raw will cause most people to vomit. Some rare drugs react poorly with saliva, and there are also drugs which are designed to dissolve not in your stomach but in your intestines, but those are usually not capsules but thumb-sized pills with coating so thick you won’t be able to chew through it.


  • Capsules are considered more advanced drug packaging because none of the drug dissolves in your mouth when you swallow capsules. Unlike pills, 100% of the drug goes straight to your stomach, so there’s no variation in the drug dosage, and the patient won’t complain if the drug is bitter.

    Also because you can open the capsule and pour it into the glass of water, if you have trouble swallowing pills. Which defeats the first advantage, and you can simply order powdered drug instead of pills, but it won’t come pre-packaged as pills so it will be more expensive.

    None of that matters for vitamins, you generally need more than 1000% of the daily dose for it to become harmful, so each pill contains more than your body really needs, because there are no side effects, so you can buy a pill and lick it, chew it, crush it, and add it to your coffee, and it will still work just fine.





  • You can listen to FM radio with gqrx relatively easily, if you can navigate through hundreds of input boxes.

    sudo apt-get install gqrx
    

    Anything more complicated will require some coding knowledge, unless someone already created a library for that specific thing.

    There is also a ready-made package to listen to GPS signal, unfortunately it needs an external amplifier and a proper antenna, because RTL-SDR is not sensitive enough for GPS.




  • So if I’m developing a garage door opener using ESP32 RISC-V module, I’m not a RISC-V developer? The dev tools and the cross-compiler only come in x86_64 variant, they simply won’t work on RISC-V laptop. But at least they provide a Linux installer.

    The only use case I can think of is to build Debian packages on a target architecture without cross-compilation, because many packages do not support cross-compilation, but it’s more an issue of poor build scripts.




  • Busybox was quickly replaced by BSD-licensed Toybox everywhere for that exact reason.

    Copyleft licenses (like the Gnu General Public License) mandate that all derivative works remain free.

    This is false. It’s perfectly legal to take GPL-licensed work, modify it, and sell it. As long as the work itself does not reach the general public, you don’t need to release it’s source code to the public (e.g. your work for the military, you take money for your work, and provide source code to them, but not release it publicly).
