Re: Bridge Command ship simulator for Pi - request for testing

Cool that worked. Bridge Command running on 64bit Pi4 :D Did not notice much difference between Gentoo64 and Raspbian. Might have to run them side by side. Google shows that fix seems to be applicable to other apps too. Edit- I tried copying the files to an uSD card that had Sakaki's Gentoo64 Lite w...

Re: FreeCAD on PI4 and Raspbian Buster.

but is it common for something to be broken for this long? Not in my limited experience. But the mainstream is mostly x84_64 these days. Android is now mostly Aarch64. Raspbian is Arm6/7/7l. Raspbian is NOT a common OS outside of the RPi crowd. Open Source apps that use so many external dependencie...

Re: Coding book, from beginning to intermediate

I'm taking a leaf from the kid and now watching YT's.
Very educational in a non detailed basic way.
Plenty of github example code around too.

Hard to find non Windows/Unity/Unreal examples.

Not sure if only 12weeks of a Z80 TAFE course in the 1980's set me up as a future Computer Software Engineer?

Re: Is the Pi4 ARMv8 compliant ?

Perhaps 64bit aarch64 OS is the question.
But then that would be software not hardware?

And yes to that.
A few choices now for 64bit ARMv8 OS's.
"uname -a" is useful to find out the OS

Re: Sandisk Ultra Plus or Extreme

A1 rated cards are all you need.
16GB Sandisks are my usual low cost uSD $4 choice.
They only need to hold the booting OS, then swap to USB3 to SATA harddrives.
8 x 16TB Ironwolf Pros will cost much more.

Interesting project, but in honesty I dont see anything directly relevant for the Raspberry Pi.

Make that "many, many, many times faster" if you run your processes on the 128 core GPU. But that makes it too easy, because it will just work and I won't learn anything.
