I posted this link about Windows 3’s architecture and VMs a while ago, but this topic continues to fascinate me. Raymond Chen brought it up again recently.

I’m aware that virtualization itself is much older than Windows 3 (IBM did it in the 1960ies, I believe?), but knowing that similar concepts existed in my tiny little machine that ran Windows 3.1 is just mindblowing. 🤯 (Alright, it wasn’t exactly “tiny”. It was an IBM PS/2 Model 80. 🤣)

In-reply-to » @eapl.me There it is! https://www.youtube.com/watch?v=HDicLHBvQQM 🥳

That last story he tells there (about the masked interrupts), that’s what fascinates me about computing. 😍 You’re close to the machine and you’re dealing with interesting problems. I find this way more intriguing than all the “modern” hyped stuff like “““AI”””.

In-reply-to » See, even a video I was just watching on Youtube just now, the guy said:

@prologic@twtxt.net

I’m willing to get that Google™ is losing ad revenue from sponsored advertising and sponsors of Youtubers.

That sounds like a plausible explanation to me. (Then again, I have little insight into how “making money on YouTube” works. 😅)

Like @lyse@lyse.isobeef.org, I skip these sections immediately, unless it’s just one or two sentences. If it’s too long, I might just close the tab right away. 🤷

@prologic@twtxt.net I don’t have a clue if they work or not. 😅 There are probably studies, but I’m too lazy to search now. 🤣

I, myself, don’t remember even having clicked on one of those banners and then proceeded to actually buy something. But what certainly does work on me is the effect of hearing/seeing a certain brand over and over again. “Oh, that’s a Logitech mouse, I know that manufacturer.” Stuff like that.

@prologic@twtxt.net What I “love” about this is that the popup randomly disappears after just 1 or 2 seconds – and then reappears a litle while later. 🫤

In-reply-to » There is a lot of Black Friday promotion happening in Germany these days - I wonder however how many Germans really know where it comes from? Happy Thanksgiving to whoever is celebrating today - as it is one of the few US / Canadian festive days where families - really - try to enjoy their time together.

@johanbove@johanbove.info I had no idea where it came from. 😅 There are so many “black $something” throughout the year and similar sales events … It was news to me that it’s related to Thanksgiving.

In-reply-to » Firefox’s new option to automatically block/accept cookie banners feels super useful. 😍 At very, very wrong. We shouldn’t need this. Oh dear.

@shreyan@twtxt.net Well, I think it’s more of a workaround than a solution. And there’s a lot of guesswork needed from Firefox – that’s why I probably won’t enable this option. It needs to guess which elements to hide and, if set to the more aggressive option, which elements to click (to discard the dialog). That sounds very wonky. 🫤

In-reply-to » You'll never guess what I learned from https://www.uninformativ.de/blog/postings/2023-11-19/0/POSTING-en.html. I've never seen for i do in shell scripts. Turns out, that walks over all positional arguments. So I reckon my for i in "$@"; do can now be shorter from now on. Very interesting in that detailled explanation to see all the – at least to me – inconsistent handling of semicolons and line breaks.

(I think I first saw for i; do in Shell-Skript Programmierung by Patrick Ditchen from 2008: German excerpt. They didn’t mention any restrictions on shell versions and I’ve been using it for ages. 😅 (I’m not too happy that the book uses for i in $* as the default template instead of for i in "$@". The book doesn’t care too much about file names with spaces in them.))

@lyse@lyse.isobeef.org Oops, I must confess that I didn’t check whether that’s POSIX or not. 😬 So, thanks for the link. 👍

It really is a shame that there’s no guarantee that a shebang of #!/bin/sh enforces true and strict POSIX-conformity. This is all so fragile. 😞

In-reply-to » I think I’m going to do this year’s Advent of Code in C and see how much of it I can get to run on DOS. Not a novel idea, people have been doing that a lot in recent years. I’d just like to join in on that. 💾

@prologic@twtxt.net Yeah, you certainly get no argument here when it comes to Ruby. 😅 (I’m much more familiar with Java, so I don’t perceive the things you listed as a problem there.)

In-reply-to » I've been reading "Shareware Heroes: The renegades who redefined gaming at the dawn of the internet" learning of games developed before I was born, or when was too small. I'm finding old gems to play and understanding that we have the same problems developing games 30+ years after, although with some obvious differences.

@eapl.me@eapl.me Which problems are those? 🤔

The only “advanced” Tetris I played back then was “Block Out”:

Except it didn’t run nearly as smooth as in this video. 😅

In-reply-to » So.. Of y'all that had covid. Did you have at the end a night where for no reason your brain amped up to 11 and can't sleep at all? It happened to me last night and my FIL the night before.

Phew, am I the only one around here who hasn’t had Covid (yet)? 🤔

@prologic@twtxt.net Why, don’t you like it? 😅 (I’m quite indifferent to most programming languages, but Ruby is “special”. It’s very incompatible with my brain. 😬)

@lyse@lyse.isobeef.org Yeah, I actually wanted to buy one of those. The shop where I was didn’t have them, though, only digital ones. I didn’t think much about it and never expected it to need batteries. 🫤

@lyse@lyse.isobeef.org I suspect that they put a battery in this time switch (is that the correct word for “Zeitschaltuhr”? 🤔), so the thing doesn’t lose its settings in cases of power outages. I would have thought there are better ways to do that, though … (Honestly, I wouldn’t care if it lost the settings. It’s irrelevant for my use case. But it was the only model available, so I had no choice anyway.)

I’m currently preparing for this a bit with some skeleton code and a few libraries. I can’t get over the fact that most of the code I’m writing on Linux just works on DOS. 😳 The C compiler I’m using on DOS is from 1992. 🤯 Some modern stuff and some POSIX functions are not available, yes, but I can work around that.

@mckinley@twtxt.net Hmm, I have not perceived this to be much of a problem in the past … but I admit I’m getting quite careless in this regard.

@lyse@lyse.isobeef.org Asking DuckDuckGo real quick turns up this:

https://docs.libreoffice.org/slideshow.html

So, I guess you don’t get to enjoy nice fancy physics animation effects in Impress. 🤪

Long story short, I just uninstalled LibreOffice. I hardly need it anymore these days.
