    it’s used to verify that OpenGL ES2 works onn 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.





  • You can set up your own IPv6 server, and it will be accessible from every other IPv6 device. Do you want to create a Lemmy server using only your phone and Verizon mobile data? Yes you can! *

    * Instructions for installing Linux environment on Android phone and setting up free DNS and HTTPS certificates are not included.

    That’s the main point. IPv4 fails because half of all existing IPv4 devices cannot access the other half of IPv4 devices directly, they have to go around using some kind of relay server, which inevitably complicates communications and costs extra money.



  • If you want to understand how 3D projection works, it’s better to solve a few trigonometric equations by hand on a piece of paper, then copy these equations to your Python code.

    If you just want to quickly make your own 3D renderer, simply use OpenGL API and the corresponding projection matrix. It will run the same exact formulas inside the driver, just in a 4x4 matrix form, and you can simply experiment with modifying each element of your projection matrix to make your 3D scene rotate the way you want, without bothering to understand the math.

    Simply copying some formula from the net will most probably fail.






  • Well, uh, I hope your power supply can provide 3 Amperes.

    Also you need to explain your network architecture. Does your Pi 4 connect to the internet using WiFi, and provides internet to Pi Zero? Your should see Pi Zero as USB-Ethernet card on your Pi 4, and you should be able to create a shared connection on this card from Pi 4 system settings if you connect a monitor and a mouse to your Pi 4.






  • I had the root canal done without an anesthesia, because I did not want a needle sticking into my gum.

    It was tolerable, I did not cry or anything like. The nerve was mostly dead anyway.

    The dentist took his sweet time removing the nerve piece by piece with a probe, instead of just drilling the whole tooth through. It did not matter at the end anyway, because he filled the canal afterwards. And the molar has three roots, so he repeated that two more times.

    I guess it depends on your pain tolerance.
