There is no such thing as an "AI". It's just a marketing term for so-called neural networks (that supposedly emulate a brain) running large language models. They don't have intelli…

It's now been about five years since I heard about the Rust programming language for the first time. It was when I was starting to write an operating system in C and the "Rust peop…

More than a year ago I wrote a document that I named "UEFI fact sheet". The purpose was to create a more truthful counterpart to a similarly named document which the UEFI forum was…

ST-DOS is a DOS implementation, but it is not meant to be a clone of MS-DOS. It is mostly syscall-compatible with MS-DOS, but the driver API and many other things are completely di…

>I was there too. People always say this, but just because a thing changed once does not mean it will happen again. The problem is that the web standards have now grown so much tha…

The text was too long, so I had to put it in pastebin.

> Non-corporate-supported browsers might transition to being more friendly to this process instead of the unhelpful and scary SSL warnings provided now. That's exactly what I would…

When I'm talking about "lookalike domains", I mean domain names that look exactly the same. It is simply not possible with 7-bit ASCII. A self-signed certificate can also be used t…

Clearly it is not suggesting anything like that. You misunderstood it on purpose.

I am living in reality. I don't want to limit the user's freedom. Sometimes people have to learn the hard way, but the other option (giving away your freedoms) is always worse.

1: You can always use a stronger encryption. You don't have to use decades-old encryption that has already been compromised. 2: So clearly in this case the route wasn't trusted. Th…

After the OOM handler had halted everything the 10:th time, I finally decided to do something (at least the kernel and the TCP/IP stack seem to be very stable, because it still did…

A hello world for an IBM PC compatible does not require much. Sadly UEFI has made everything exponentially more complex. If you want to be more minimalistic, this also works with i…

I recorded that video from a computer that is connected to the same ethernet hub as the 486 server.

Yes. I wrote a special mouse driver that hooks to the keyboard interrupt and makes it possible to use the numpad keys as a "mouse". Sadly most DOS programs seem to replace the BIOS…

It consumes about 30 watts.

Considering that it has to be able to handle about 100 new sockets per second, one socket requires about 1 kB ... 2048 kB (?) of memory depending of the size of the buffers and how…

Everything in my "operating system" is 16-bit x86 code. It uses regular DOS packet drivers. I have also started writing my own DOS kernel, but it is not ready yet. The server uses …

Yeah, a 486 is not a slow CPU - not even the 25 MHz SX version that the server has. But Windows 95 is a 32-bit protected mode OS. My OS also works on a 8088, but I don't have a 808…

I think the user will most probably keep pressing the F5/Refresh button anyway if the site is not working at the first try, so responding with a RST packet would just use more band…
