Re: Design Ideas

I have seen engineers discussing and solving problems over beers from London to Chelmsford. From Helsinki to Milan. From San Jose to Mountain View. So that's why designs are so slow here these days, no beer. The synergy of more than one makes for much faster solutions and beer helps take the mouth ...

Re: algorithms and ethics at the Barbershop

This is what scares me, to the core. Me too, which is why I'm studying it now. We fear the unknown? Lots of people are happy believing in a system they think mostly work, until they dump heads with the system. Then it is "The system does not work", "anything must be better than this".....

Re: algorithms and ethics at the Barbershop

The ethics is not in the algorithm or the data. It's in those who build and use it. Those who build it and train it might not be those who use it.

I doubt that has been tried before. Perhaps you might get better results with Gentoo64, or just stick with 32bit Raspbian where it all works./ To boldly go where no one has gone before! Except Sakaki ;) It looks like Ubuntu is a few versions of Mesa behind Gentoo64. I didn't like Ubuntu and now pla...

secondhand, all valid points, BUT... Gentoo64 is not a beginners OS, it is one person's (with help) version of a niche Linux distribution. Any Linux distribution can never be perfect, those little niggles are what drives peoples "improvements". Pi4 1GB, browsing barely works. Pi4 2GB, usable browsin...

Re: Future of raspberry pi

In the meantime, I would really like a CUDA-like programming language for the VC6 to allow young programmers an opportunity to learn how to use a GPU accelerator in their code.
The closest I have seen so far.

OpenCL and Pocl are two to keep a watch on.

Re: RPi 4 OpenGL ES 3.0 ShaderToy to download (100+ examples)

Shaders use the GPU.
I found it worked fine on the 1GB.
But if you need to use a browser then the 2GB is better.
If you want to browse and compile at the same time then 4GB seems enough.
