This[1] demo does pretty convincing dynamic lighting without the need for RTX relying just on regular shaders. To me nvidias RTX looks like a gimmick with the sole purpose of enforcing vendor lock-in. 1.: https://www.youtube.com&

If you like Syd Mead check out Klaus Bürgle. To me he nails the Futurism genre like nobody else. Here[1] are some "Space" pictures starting as early as the late 1940s. 1.: http://klausbuergle.de/buergle_weltraum1.h

Both GTK and QT are exceptionally bad toolkits and are part of the reason the Linux Desktop never took off. Giving GUI toolkits responsibly for even more things is clearly a bad Idea. Also personally I like the fact that inertia scrolling w

If you use froward rendering, which means placing a bunch of textures on the screen, you are not really "drawing". We are probably not talking about the same thing.

I'm experimenting with GPU based 2D rendering using signed distance functions as drawing primitives for quiet a long time now. My experience is that as soon as the object tree exceeds a certain size the CPU will always beat the GPU. Th

So far no pure GPU 2D rendering exists. Skia moves some tasks to the GPU that and leaves others to the CPU. This is the worst of both worlds because you need as much memory as before but you have more bandwidth pressure on th PCIe bus and

Halfway through you were bringing up hopes for a great new way to do 2D rendering on GPUs but then there is no show of actual implementation. Rather anticlimactic! Even decades old Cairo is beating VulKan/GPU based renderers like Skia

Because of the inherent "everything is s String" mantra tcl/tk is to this day by far the best language to rapidly build GUI front ends for CLI applications (which generally spit out strings to stdout). In our company I recent

A 32-bit key and 32-bit value are some serious constraints. The whole point of hash tables is usually that you have variable length keys or values. If you have more than 32GB of RAM (which is not rare nowadays) you can directly map all 32-b

Why is X11 able to be tear free (if drivers a configured properly) and still allows single applications to disable vsync? I still don't understand why I need Wayland.

Performance was worse than X11 for a long time[1] and is finally catching up for some singular compositors. However most compositors still have worse performance and every single compositor has different quirks. Latency still seems to be wo

At this point Wayland is nothing more than a 10 year old, over-hyped, tech-demo. Why should Nvidia care about sub 1% of a sub 1% market?

But MIPS 64 bit didn't outperform the fastest 32bit processor on the market by huge margins. That is what I meant by "viable".

DEC was on the forefront of so many technologies and did set so many standards (first Unix machine, vt100, first viable 64-bit processor, first viable search engine, much more even before that). It is sad to see that this company and its pr
