If you happen to have a Fritzbox with VoIP capability it contains a SIP server and you can register SIP clients on it (e.g. Fritz App Fon, linphone, twinkle) and use them to phone internally.

You can use your phone with mobile connection (not WiFi) to check if it can see the file that you made available on your web server.

But Admiral Patrick (sorry, I still don’t know how to link/tag users) wrote he has to scan and email the physical signature from the paper, so it is not really physical anymore? Maybe he has to send the physical paper by snail mail in addition to the email.

have to print, sign, scan, and email back

Can’t you scan or photograph your signature and insert it in your word processor?

You’re correct that it won’t draw 650W. You could get a power meter or a power measuring plug and measure the energy consumption.

HTTP3 uses UDP, which is 6 years younger than TCP.

I use Firefox on Linux, Windows (at work), and Android, and I like it.

Don't put it in /usr/bin, that's where your package manager puts executables, not you. Other than that, do what you want. /usr/local/bin is good, or if it's only for your user ~/bin, ~/local/bin or ~/.local/bin - I don't care. Also just let your users decide where they want to put the script.

The underscore is used to underline text in Markdown. If you want to display a real underscore like this: _, you have to escape it with a backslash. Some clients apparently interpret this rule even in plain links, and some don't. If we use real Markdown links this should not happen.

I searched for “lomiri rotate screen” and found this page.

Oops, sorry, I misread your question.

Did you check the wiki entry?

I’m not sure, but I think these USSD/GSM codes still work nowadays.

I used DVB-S/S2 cards and DVB-T sticks for many years with VDR, but a few years ago I gave up and got a separate tuner box (Octagon SF8008). I was fed up with the kernel module compilation, and the DVB cards or USB boxes only lasted a few years until they died. Every time I wanted to record something, the desktop PC had to run. All the time I used the PC the cards were powered and that probably didn’t help with their longevity.

Yes, if you already know that you can drag and drop between unrelated programs, it will work like you expected it.

If you don’t know it, you can pick it up by looking over the shoulder of your friend or co-worker, or you can read articles like this.

Reading about Kernel processes and executing threads makes very little sense compared to a hardware core with two threads.

For me it’s the opposite: a hardware core “having two threads” still sounds a bit strange. It can run two threads at the same time. Maybe Intel should have invented a better name for the thread-runner-thingie.

Programmers use rubber duck debugging sometimes.
