  • 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.






  • 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.







  • 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.


  • Most vector rendering libraries have options to disable all the fancy stuff like Javascript and external links. If you manage to find one that supports it in the first place. As for resource usage, the server sends image files without decoding, so whatever forkbomb you will manage to include into your SVG will only crash Lemmy clients, so, ‘not our problem’. Maybe it will become a problem for the server when generating thumbnail image.





  • 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.



  • Hey, do you maybe know the Polish alphabet song? I was searching for it on the internet forever, but I don’t speak Polish so I could not google the correct phrase. It started like this (reconstructed from oral lore using Google Translate):

    Berlin miastem w Niemczech leże

    burdel - miejsce dla młodzieży

    guzik to jest częścią ubrania

    gówno jest produktem srania

    dynia to jest do jedzenia

    dupa to jest do pierdzenia

    And it supposedly continued all the way to letter Z.
