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 intelligence, they are merely guessing machines

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 people" (as they seem to often refer to themselve

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 spreading on various Internet sites. For a long t

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 different. After all the definition of DOS is just "disk

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 to make sure that the connection is private. S

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.

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 not crash!) I set the maximum amount of sockets to 32,

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 if the BIOS is newer than 1/10/86 (written in NASM

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's keyboard interrupt handler with their own,

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 the congestion window is implemented[1], I'd say that

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 FreeDOS kernel. That's why I write the "

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 8088 computer that I could use as a server.

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 bandwidth and resources.

My OOM handler killed the HTTP server process. Now I restarted it - the HTTPD process, not the computer.

The TCP/IP stack is compiled for 64 sockets. If the socket table is full, it just drops all new SYN packets and does not answer to them.

My system is 100% 16-bit code and cannot access more than 640 kB of memory, and that's why it is so limited. I could probably increase the maximum amount of sockets and file handles to give it more capacity, but it still has its limits
