I’ve identified several issues with my current (admittedly cheap) upright bass by now. It might be time to upgrade to a better model. 🤔

If only those things weren’t so damn expensive. I just checked the prices and simply burst out laughing. 😂

@lyse@lyse.isobeef.org (I think of pointers as “memory location + type”, but I have done so much C and Assembler by now that the whole thing feels almost trivial to me. And I would have trouble explaining these concepts, I guess. 😅 Maybe I’ll cover this topic with our new Azubis/trainees some day …)

@lyse@lyse.isobeef.org I guess the thing is that usernames are no longer needed for many popular things, like WhatsApp. “Just install the app”, done. When I ran my Matrix server for our family, this was the first thing that people were bummed out about: “Oh, this needs a username and a password? Why doesn’t it just work? That’s annoying.”

People are less and less exposed to “low-level” details like this. There was also this story in 2021 about the concept of a “file”: https://www.theverge.com/22684730/students-file-folder-directory-structure-education-gen-z

I lost my original Windows 95 CD (and it’s too expensive for my taste to buy on eBay), so I finally sat down and got an old disk image of one of my PCs to work in QEMU.

I don’t intend to do much with Win95. I just want to be able to boot it, if I want to check how certain things worked or looked in that version. The purpose of this really is to be an archeological digsite.

@lyse@lyse.isobeef.org There’s a reason it’s called “(n)curses”. 😏 The only advice I can give is to never fiddle with reassigning control sequences and $TERM variables. Leave $TERM at whatever value the terminal itself sets and use an appropriate terminfo file for it. If there are programs misbehaving, they probably blindly assume XTerm and should be fixed (or have XTerm as a hard requirement). If you try to fix this on your end, it’ll likely just break other programs. 🥴

@kat@yarn.girlonthemoon.xyz Using full-blown Cloud services is good for old people like me who don’t want to do on-call duty when a disk fails. 😂 I like sleep! 😂

Jokes aside, I like IaaS as a middle ground. There are IaaS hosters who allow you to spin up VMs as you wish and connect them in a network as you wish. You get direct access to all those Linux boxes and to a layer 2 network, so you can do all the fun networking stuff like BGP, VRRP, IPSec/Wireguard, whatever. And you never have to worry about failing disks, server racks getting full, cable management, all that. 😅

I’m confident that we will always need people who do bare-bones or “low-level” stuff instead of just click some Cloud service. I guess that smaller companies don’t use Cloud services very often (because it’s way too expensive for them).

I saw 100% I/O wait in htop today but couldn’t find a process which actually does I/O. Turns out, I/O wait isn’t what it used to be anymore:

In my case, it was mpd which triggered this:

https://github.com/MusicPlayerDaemon/MPD/issues/2241

mpd doesn’t actually do anything, it just sits there and waits for events. To my understanding, this is similar to something blocking on read(). I’m not quite sure yet if displaying this as I/O wait (or “PSI some io”) is intentional or not – but it sure is confusing.

@andros@twtxt.andros.dev Hm, looks correct to me. The image to be displayed is a thumbnail and this links to the full-sized image. The thumbnail (JPG) is auto-generated from the full image (PNG), hence the two extensions.

What does look strange, though, is that your client came up with the hash pqsmcka, while it should have been te5quba. 🤔

I think I should try self-hosting some Mastodon thingy again.

The “export data” feature on the Mastodon instance I’m using seems to be broken. I’ve contacted the admins but we couldn’t find the issue – yet. I don’t want to bother them too much, it’s a free service after all.

But this means that everything I post over there is very, very volatile. It could all be gone in 5 minutes and I’ll have no way to restore it. Hmm.
