This morning I saw this interesting YouTube video that introduces and reviews the Pi 400.

Re: The Raspberry Pi 400 thread!

ive also been looking into the video hw, and things like a lightpen/lightgun should be feasible on even the pi4, but obviously only on CRT based outputs Try bhphotovideo.com, they have all kinds of them. Just type micro hdmi in their search box. (I do not work for them, I am just a happy customer.)

Can someone please tell me what the length of the HDMI cable 1m the USB-C/PS cable enclosed with the $100 kit is? 1.5m Also, is the USB-C cable hardwired on the PS end, or is it replaceable? They're bundling the official Pi 4 PSU so it is permanently attached. Finally, is it possible to buy a separ...

Re: KDEnlive keyboard input mess

Hmm... Am I the only one having this problem?

I wonder if it is not just KDEnlive, but perhaps KDE itself. I have no idea how that could/should be configured.

I am actually connecting to my Pi 3B+ using TightVNC, but I have no keyboard issues with any other application. Only with KDEnlive.

Re: OpenVPN - change and refresh connection

Personally, I just do:

Code: Select all

sudo killall openvpn
And then I type the command to run OpenVPN with whatever configuration I want.

KDEnlive keyboard input mess

This is on Raspbian, Pi 3B+. I was looking for an effect in KDEnlive, so I tried to type its name in the effect search window. But what appeared in that window was complete garbage, unrelated to what I was typing. For example, I typed Koliba Erythropy but this what it showed:

Re: Installed great, now where is it?

Re: Parsing the command line

Yes, the startup code adds to the size, as does the C library (even if it is dynamically loaded, it takes memory). As for the meme of C compilers being so good, sorry, that is a myth. They often can optimize code quite well, but they still have to err on the side of caution. I have been computing si...

The Logitech Unifying devices have worked great for me.
How does that work? Can you have a different set for each computer and will the computers (or the dongles, rather) know which keyboard/mouse is for which computer?

Like the Pi 4B, a 64-bit version of Raspbian may happen sooner than people think.
As long as it can run both, the new 64-bit software and the old 32-bit software, it will be a step in the right direction.

Re: Parsing the command line

Yes, I’m quite impressed by the simplicity of ARM, too. Indeed, I am quite surprised that desktop computing has not switched to it yet (or something very similar to it). Intel processors have grown way too big, which makes them very expensive and also generating too much heat. Quite a departure from...

Parsing the command line

How do you get the command line parameters in a program written in straight assembly language? I mean, I know you can start with main and use gcc to link it, but how do you it without relying on the C library?
