  • 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 has always been possible to live without petroleum and coal, without deforestation and extinctions, without international finance capital and instant digital commerce, without immigration laws and border walls, without corporate and state surveillance and militarized police.

    To get to such a future, though, we need to pull the emergency brake on this future first. Then we can do the work of remembering how to survive without all these things, the way humans have done for thousands and thousands of years.

    Yeah, no. I’d like heating in my apartment during the winter. Coal is kinda essential for that, until we upgrade all our generation to wind and nuclear power. The fact that humans survived without coal in the past, well, they simply died by the thousands.


  • It really depends. One specific shop near my home has good quality frozen meat pancakes and dumplings. Yeah I have made dumplings by hand some 20 years ago, but those frozen ones are simply better. Maybe I can do some exotic dumplings with a buckwheat flour and a lot of eggs, but that would not necessarily be better, just different.

    On the other hand, pasta sauce prepared from scratch will always taste better than store-bought one, mainly because the stores here only sell ketchup and mayo, and pretty much all pasta sauce here is some variety of tomato concentrate with a bit of carrots.


  • 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.
