Re: Wifi connection unstable

I fixed this for my Pi 3 B by disabling Wireless Multimedia Extensions (WMM) in my router. Those contain some power saving feature that, if it suddenly turns on, will halt all traffic. I'm running a minimal installation of Raspbian Buster. It'd be good to be able to use the Pi in a WMM enabled netwo...

Re: [SOLVED]How to remove the raspberry logo during boot

Is it possible to remove the logos after Raspbian has booted? I am not using graphical login and I seem to have only one virtual terminal.

I realized that running raspi-config and immediately quitting does it. But stty sane or pressing Ctrl-l do not.

Re: Memory Bandwidth of the Pi 4B

I think it's very simply that in those Ryzen systems, the limiting factor is a resource that is shared among the cores, with the sharing causing little or no side effects. In Pi 4B there is some shared resource with which the sharing causes a side effect. Of a limited magnitude, it seems. I'd guess ...

Re: Why did raspberry pi become a good device for creating a server?

Are there any small and inexpensive computers at all with ECC memory?

Was there a NAS project once somewhere that did have that?

Or did they have it just basically and theoretically but nobody was sure if they really had that, or at least there was no way to verify?

I think the problem that's being referred to is visible here:

And this happens constantly. There are even parts of the level missing. Reducing the resolution doesn't help. Increasing the GPU/RAM split to 256 MB doesn't help. This is 1920x1080 though.

Re: Raspbian Buster uses old version of youtube-dl that cannot download anything

youtube-dl has its own, internal update mechanism. You simply invoke it with youtube-dl -U.

Of course you need to run it as a user who has write permissions to the executable. I have it in my home folder in a subdirectory.

It's not default, because it needs much more CPU cycles and is only required for some mouse/keyboard combos with a strange behavior. Much more is how many?
