Re: Native Youtube application for raspberry pi?

Freetube runs in Gentoo64, I just downloaded the binary arm64 version.
A recompile for A72 might be faster?

Re: Raspberry PI Zero W OpenGL support

OpenGL has been running on Pi3's in Gentoo64 for 2 years? That's a 64bit OS but the same VC4. Buster will have newer Mesa drivers and be compiled for 32bit. So a lighter OS like PiCore with the newer Mesa drivers would be fastest VC4 OpenGL solution? How much performance difference is there between ...

Re: RPI4: Why is everything still 32-bit?

First time poster? There is now more than one 64bit OS for Pis and Gentoo64 has been working for 2 years on the Pi3B's. 64bit OS's have been a bit DIY, time will fix that and there will be more Linux and other Distributions that just work. Aarch64 OS's and "all" the software that might run on them a...

Gosh, this is on a very old spec of Pi and they run really well!

The older Pi's only do OpenGLES 2.0, lower capability shaders.

Re: A modest (passive) suggestion

Speed controlled by USB? 4 USB ports = Pi drones?
5V at 1.2amps = 6 watts, nope not enough power for takeoff.
But old toy drone motors would make small fans.
The smallest would be the 4mm dia tail rotor motor from the RC helicopter toys?

Re: Looking for specific software

Do a google for Linux Postit notes, see what shows up.
Try to apt-get install them.

Debian might be behind so if install does not work try grabbing the source and making the app yourself.
Some stuff just works now on Pi4's.
It is sometimes just a case of no one has tried it before.
