Except of course how return addresses are typically always stored on the machine stack. It is very concretely there and part of the programming model, in my world.

I didn't get the part about the stack in assembly, in my experience the stack is very much a thing at that level. Mainstream CPUs expose one or more explicit stack pointers, and in assembly you use that all the time, right?

Sounds like Xplora [1] to me. I assume they have an English-language site but failed to find it and it's late, sorry. [1]: https://xplora.se/

Meta: the mseal() prototype in the article needs some editing, it is not syntacticallly correct as shown now. The first argument is shown as unsigned start addr But should probably be unsigned long start_addr

Meta: the naming is ... strange. The actual name of the repo is "pretty.c", but the name used for the language/dialect/result/horrorshow[*] is "Pretty C". The actual code file you include is called "p

I don't have anything to say about the artistic value, but as a part-time tool collector with dreams of being a handy person, this passage was the most interesting: I used a puncher to cut a hole in the frame’s cardboard for the camer

I know I'm getting old when I have to stop and check for satire at the mention of "a breathing app". That sounds like an Onion headline, to me. Glad you had success!

No actual C programmer who has been around the block more than halfway should do that. The mantra is: "read into a character buffer, then parse that". It's more code, sure, but it buys you a lot of good things. I/O is ha

I'm sure you know this, and perhaps it's way too late, but still: the STM32s can certainly use DMA to write to GPIO pins. See for instance [1] (not my project, just a random search hit that seemed nice). [1]: https://gi

As someone who fits the description rather too well (although neither my teenage or current self would ever use a marker in the Hardware Reference, omg) this was really nice and satisfying to read. In a weird sense it kind of helped me feel

Thanks! My memories of "Virus" was that it was super-mega-difficult, but of course it was the late 80s and games were not afraid of having a bit of a learning curve to them. :)

According to Wikipedia, "Lander" is only a demo, the actual game is "Zarch" [1]. Later ported to the Amiga, and renamed "Virus" (which is the title I knew, having grown up on the Amiga). Very impressive, and co

It's awesome that they combine 1" pipe with a 5 mm hex [1] (often "Allen" in the US) fastener. :) [1]: https://en.wikipedia.org/wiki/Hex_key

That is an epic use of "protect" in a very unexpected way. Thanks.

Meta: I don't think "close" should be title-cased here, and indeed it isn't in the article. Also, I think it should be `close()`, with parens, that is the conventional way.

Very nice, I'm always for more assembly-level programming and education! A very minor grammar thing, here: In our example, the mnemonic is mov, which stands for move, and the operands are rax and rbx. This instruction in plain English

Probably ounces ("oz") for something like this, so around 0.005 oz then. The original 100 kg is equivalent to 220.5 lbs (which is pronounced "pounds", of course).

As someone with both a) an engineering-interested kid and b) a mild AliExpress addiction, that is some dangerous stuff. But thanks, hadn't seen those!

Uh, I've never worked with them, but the linked Wikipedia article states that the US Navy did early development in order to create equipment to move things aboard aircraft carriers. I've never been to one of those, either, but it
