In-reply-to » Low-quality smartphone shots from today’s walk:

@lyse@lyse.isobeef.org It’s probably better for them if they’re shy. 😅 But yeah, if they’re used to humans, they won’t run away so easily. At least the ducks won’t – the rails/moorhens do. 🤔

Ahh, I remember those Asperg shots. 😅👍

That whole area with the tunnels and basins is probably some sort of “retention basin” (Regenrückhaltebecken), with several levels to reduce the flow. There’s almost never a lot of water in there, though. Not sure if this structure just isn’t used anymore or if it’s too dry. There’s also this “pole”, it’s a bit hard to see, though:

Looks like they’re trying to measure the water height (Pegelstand)? The pole is super high and I doubt that any rainfall will ever reach the top of it. 🤔

In-reply-to » After a bug in the Open Watcom OS/2 resource compiler has been fixed (imagine that – they still fix bugs related to OS/2! 🤯💚), I was able to make some more progress with the OS/2 GUI version of my little disk usage tool. It now has a menu bar and a dialog to open another directory:

There you go, multithreading. 🥳

I tested this in QEMU, which luckily supports throttling disk I/O, so I can make sure that scanning the disk actually takes a while.

(Still boggles my mind a bit. When OS/2 2.x came out, DOS was still the norm for us and I didn’t even know what multithreading was. I really didn’t appreciate this operating system enough back then – only now.)

QOTD: Hello Linux users, what do you use to monitor your network traffic?

As you can see in most of my screenshots, I have a widget at the top of my screen that shows the current bandwidth usage:

https://movq.de/v/303e1b1cad/a.jpg

But what does that tell me? What do I do when I see a sudden spike and I don’t know where it’s coming from? 🤔 I don’t have an answer for that. I’d like to have something like a summarized log of the recent network activity of all processes.

Something like tcpdump doesn’t help here, because the traffic is often already finished when I notice it.

The video includes the ZMODEM transfer process of the 50 kB .EXE file from my laptop. It’s a bit lengthy, but I kept it in for nostalgia. 😅

Next up is probably multithreading: Do the disk scanning in a background thread so the UI doesn’t freeze. (This is running on a Compact Flash card, a real hard disk would be much slower.)

In-reply-to » Wrote a little wrapper script that lets me use T in DOSBox as a generic editor. Works with twtxt, too! 😆 Only downside is that I can’t use X11’s copy-and-paste. 🤣

Proof! Irrefutable proof! 😂

(This is silly without copy-and-paste. 🥴)

In-reply-to » Alright, the Compact Flash adapter in my retro box works fine now. It allows me to switch disks way more easily, which, in turn, allows for more experiments. 👌

Well, it’s not pretty yet, but I’ve got a very basic GUI version of dusage going:

To me, it’s just super cool that I’m able to write programs for OS/2. 😎 That operating system will always hold a special place in my heart, I guess. It ran on my Model 80 back then (and maybe even the Model 30, but I’m not 100% sure anymore) and thus a lot of my earliest memories about using computers are OS/2 related. (And DOS related, of course. I had a dual boot setup on the Model 80, believe it or not …)

Anyway, writing that little program got much easier after I’ve found this page which contains a lot of valuable information:

This is a collection of OS/2 books by a person who’s apparently quite active in the realms of ArcaOS (one of OS/2’s “descendants”).
