For those who don’t know, Graydon Hoare created rust language after seeing memory bug on out of order elevator.
How does one see a memory bug on an out of order elevator
He knew something was wrong with it’s memory when the elevator didn’t remember him
I don’t know how to see a memory bug in an out of order elevator, but I once saw and reported a wiring error of a working elevator. It was an interesting talk at the reception desk, but as I could precisely describe what was wrong and the verifyable consequences, they took me seriously. And sent me a “Thank You” email later ;-)
Were your working on the elevator or just riding it? If the latter, I imagine even being able to see the wiring was an issue.
I was just using it. But the behavior/reaction to button presses showed me that a button was obviously connected to the wrong function.
By staring at it really hard
You know how everything has LCD screens these days? And sometimes you’ll witness a good old crash? I know I’ve seen quite a few.
I’m guessing something like that.I have seen elevator complaining no bootable media found
Thank you for the context
Based. That’s a a bit like saying: “enough is enough, people are gonna get hurt. Let’s fix this.”
I really recommend creating a compiler or an interpreter from scratch, don’t even use an IR like LLVM or MIR. Just hack and slash your way though a C compiler, it’s the simplest language most people know. Don’t care about ‘optimization’ at first, fuck optimization. Just grab Yacc/Lex or a PEG parser generator that works with the language you like most and have ot generate assembly code for simple expressions. Like, make a bc(1) native compiler! Interprets are fun too. You can use VMGEN to generate a superfast VM in C, and then bind it to another language using SWIG.
Also never imagine usability. Noobdy is going to use your C compiler for any serious work. It’s just for education. Post it online to receive feedback.You cna start by writing DSLs. For example, I am implementing the ASDL language from this old paper.
Also if you are going to do it as an example in your resume, just stop. Nobody cares, because it’s a trivial task to write a compiler, even if you write backend, forntned, and the LP yourself! Do something money-loving people loike, like making some bullshit mobile app that tracks your gym sweat volume.

Oh I commented before that my b
Yeah, I noticed the times, that’s why I was letting you know. 😁
