> But what are the “awful effects” of sending FIN instead? Can someone explain? The RFC explains. The other side - the server - will be stuck on `send(sock_fd, more_bytes...)`. If …

The program in the boot sector is run similar to other software: the code is loaded into memory, and then the processor is jumped to the first instruction. This loading and jumping…

> The camera integrates incoming light into a tiny square [...] giving a brightness (and with the Bayer filter in front of the sensor, a color) for the pixel This is where I was tr…

> Audio samples are point samples (usually). This is nice, because there's a whole theory on how to upsample point samples without loss of information. This signal processing appli…

I believe it is a bug in the the emulator's implementation of COMMAND.COM. Often, these DOS "emulators" re-implement the standard commands of DOS, including the shell[1]. This is i…

Linus himself has credited Monotone with the content-addressing by SHA1: https://marc.info/?l=git&m=114685143200012 I think the main issue with Monotone was the performance. Linus …

This isn’t about signing the OS updates. This is about the device contacting Apple’s activation servers during initial setup. In the linked thread, the users have a “working” devic…

Activation Lock is a weird feature. Users love it when it helps prevent device theft. But really, at the end of the day, you're giving up control of the device to Apple. Apple has …

AIUI, another big problem with the 80286 was that it did not support returning to real mode after switching to protected mode. This made compatibility a huge issue, which was a big…

I was referring to the fact that interaction with the disk itself is asynchronous. Indeed, the interface provided by a kernel for files is synchronous, and for most cases, that's w…

Asynchronous programming is a great fit for IO-driven programs, because modern IO is inherently asynchronous. This is clearly true for networking, but even for disk IO, generally c…

This is the kind of debate that has been going on surrounding virtual memory forever[0][1]. If you can keep everything in memory, then you're golden. But eventually you won't, and …

This is an excellent explanation. If we imagine the triangle being swept about in a circle, the points in the "outer" section (forming the circle at edge of the base our our cone) …

To make an enclosing cylinder that bounds the cone in my example, we can use a 1x1 square with centroid (0.5, 0.5). The cylinder has volume π. And that works out from Pappus' theor…

If you're looking for where the 1/3 "comes from", I think using Pappus' second theorem[0] is the way to go. The theorem states that the volume of a solid of revolution formed by a …

KDE originally used CORBA, but dropped it for KDE 2.0 when it was found to be heavy for local use in a DE. https://www.linuxjournal.com/magazine/kdemdashthe-next-gener...
