Yeah, structs (records) is something I've been wanting to add and that became reasonably easy with the full rewrite of the compiler I did in 0.13. Probably in the next update!

What do you mean? FUNCTIONs are supported, and their arguments and return values are strongly typed.

New comment by jmmv in "Microsoft Needs Windows Lite"

Two years ago, I spent time studying the Windows NT kernel internals and ended up writing a comparison against Unix here: https://blogsystem5.substack.com/p/windows-nt-vs-unix-design . What I came out of that exercise with is that NT is actually well-made and was very ambitious and advanced at the time it was designed (although free systems have caught up by now).

But what I also came out thinking was: none of that shows. The kernel is great, sure, but all of the crap that has been built on top doesn't let it shine, and that's what people interact with. Take Windows 11 with is dog-slow file manager and the overall feeling that everything is bloated and designed to annoy you. I wish there was a simpler edition... but it ain't gonna happen.

> Only the very first few models of Intel Macs had strictly 32-bit processors (the 2006 iMac and Mac minis with Core Solo/Core Duo processors), and none of them were realistically capable of playing Half-Life 2.

What? First, those chips were plenty powerful to run HL2 (the game predates them). And second, all x86_64 chips can run older x86 32-bit code unmodified.

The reason macOS stopped supporting 32-bit code has nothing to do with the processors but more about them wanting to remove support for 32-bit binaries from the kernel and from all user-space libraries. To run a 32-bit binary, you need itself and all libraries it depends on to be 32-bit too, including the syscall boundary, which is "fine" (both Windows and Linux do this just fine, so it's really on Apple to have removed this). And I suppose Apple removed those because it was building towards a 64-bit-only world to simplify the Apple Silicon transition.

Is anyone still using Emacs?

Heh, gotta reference https://jmmv.dev/2023/06/fast-machines-slow-machines.html (https://news.ycombinator.com/item?id=43972004) from a few years ago. There is a video in there of Windows 2000 running on a K7-600 from 1999 and it indeed flies.

Sure, and I'm not arguing that the answers are uninteresting, but I found it odd that this is being double-quoted several times as if it was taken out of the article.

I'm curious... why are people (this thread, but there are several independent others) replying to "Is anyone still using emacs?" ? I don't see that sentence anywhere in the article!

Thanks. I haven't documented it (yet?) but I did give a talk last year on the process that got me there and the internals behind this system: https://www.youtube.com/watch?v=WZFYTInWAqc

I went through a similar "thought process" to build this: https://www.endbasic.dev/endbox.html last year. I originally wanted to "just" launch my binary right after the kernel started... but in the end settled for a full NetBSD base system to get things like network and WiFi configuration to work with ease. (That said, I still hook very early in the boot sequence to launch my own program and take over the console so that the rest of the system is invisible and initializes in the background.)

They probably meant 2010s.

I remember this was the time when Google started pushing the Chromebook idea and highlighting how it could boot in "just a few seconds". One of the earliest models I got as a dogfooding device probably needed 20 seconds to boot or so. Nice, compared to the awful boot times of machines with HDDs... but not stellar.

But then, in 2011, my wife bought a MacBook Air with an SSD and I was blown away. That thing booted to a full desktop (and not the joke that ChromeOS was) in... 5, 6 seconds? It was ridiculous.

And we have lost all of those gains. I find it painful to witness how a recent Mac chews through I/O during boot or doing any sort of software update (iStat Menus is great to watch this sort of thing), and how these feel slower to that early experience of 15 years ago :-/

> I’m starting to fall in love with CDs again.

I visited a long-time friend recently and was surprised that they were using modern LP player for music. But the surprise itself actually turned into curiosity. I got the urge to buy one too, if only to go back to the more-dedicated experience of choosing a disk from a catalog and playing it with explicit intention.

Maybe LPs are too much, but trying physical CDs again sounds like a cool idea. Especially because they can easily be rewritten and maybe I could get kids to create their own "mix tapes".

OK so, _realistically_, what can you do that will make any meaningful difference?

Shameless plug for my https://blogsystem5.substack.com/p/beyond-the-1-mb-barrier-i... article from a couple of years ago. You'll find a deep dive on unreal mode (I just learned it's also known as "vodoo mode") and some hands-on code to play with it ;-P

I'm sorry but the landing page at fuzix.org (the top page nonetheless) is terrible as it does not even try to explain what FUZIX even IS. I went to the GitHub project page, which contains some more details, but it still doesn't answer the question and only talks about how FUZIX differs from UZI.

To be honest, I still have no idea what I'm looking at.

It sounds like you haven't tried.

LLMs definitely can do this. The output tends to be overly positive though, claiming that any sort of rough draft you give them is "great, almost ready for publishing!". But the feedback you can get on clarity, narrative flow, weak spots... _is_ usually pretty good.

Now, following that feedback to the letter is going to end up with a diluted message and boring voice, so it's up to you to do with the feedback whatever you think best.
