@jecxjo@sh0.xyz Oh no! I hope you didn’t lose any changes.

@zyak@twtxt.z85b.xyz Phew, lucky!

@movq@www.uninformativ.de Hehe.

Ah, I already suspected a portability thing with -R, but my quick search was not good enough and didn’t yield anything useful. Thank you very much for clarifying!

It was a nice three hours stroll to my backyard mountain and back. 28°C, my goodness. Autumn is here with its colors. Not so much with the temps, unfortunately. At least the nights are chillier, so I should be thankful.

The great spotted woodpecker was hiding behind the leaves, so 18 was the best I managed. Still really terrible.

I think this is my very first slow worm this year in 32. Very late. And it might have been even cactus, not sure.

@movq@www.uninformativ.de Currently, for me as well. :-/

@prologic@twtxt.net Very nice! I agree with @david@daiwei.me, looks much more peaceful. :-)

txt.sour.is is down, huh? 🤔

Haha, indeed:

1. Initial uptime: A bit over 1 minute.
   
2. Changing to serial console, running uptime again: It’s down to 7 seconds.
   
3. Changing back to the VGA console: It’s again down to 1 second.
   

This really doesn’t track the actual uptime, it just happens to “mostly work”. (Like a lot of things in DOS.)

@itsericwoodward@itsericwoodward.com I’m not a hardcore OS/2 fan, either, but it does spark a great deal of nostalgia for me. 😍 For example: https://movq.de/blog/postings/2024-12-25/0/POSTING-en.html

Crazy, who comes up with things like that?

I didn’t come up with it, but I was close, I guess. DOS is so small, you don’t have much of a choice but to search for “anything related to time”. There aren’t that many syscalls/functions. You’ll quickly notice that there’s no global tick counter. So what else is there? Hmm, “get the mtime of a file” is pretty much the only other time-related thing. And which file is “stable”, probably allocated just once at boot? Mark Aitchison tried to use NUL, which is a pretty good idea. Thinking about it in retrospect, stdin does indeed make more sense, though, because that object really does get allocated just once at “boot” and then it stays the same. That’s not guaranteed for NUL (although just as likely).

But, it is possible in DOS to move “the console” to a serial port:

I wonder what that does to my little uptime program. :-)

Today, I also learned that -R is an alias for -r in rm.

Ah, I remember that. Dug it up and saved it in the blog: -R is more portable/consistent: http://movq.de/blog/postings/2026-09-30/0/POSTING-en.html

@prologic@twtxt.net Oh gosh, that looks wonderful. 😍

A few more pics if my trip 😎
