#introduction: I've been meaning to migrate over here for a long time. I'm Ryan; I'm an engineer and hobbyist. I build keyboards, pick locks, 3d print stuff, play guitar, and mess around with Linux on the desktop and server.Most of my professional energy is spent on processors these days; I've been working as a physical design engineer on CPU cores.

Just got this paclock 90A-Pro to work on. It's kind of cheating, but I like to take apart the first lock of a kind that I get. I do this partially to clean it out and apply lubricant by hand rather than trusting the factory process.

I'm currently on a plane from Chicago to Boston using in-flight wifi, and Mastodon works just fine. Birdsite, on the other hand, is completely failing to load.Engineering principle: Design for the extremes and the average case comes along for free. (This also applies to design for accessibility)

Literally just be kind to service workers, my guy at Subway just told me if I was ever running from the cops, I could hide there

Dynamic languages like "what if stuff still breaks if you don't type it correctly, but also we don't give you any hints and you don't know if it's broken till runtime"

Solidarity with the Brotherhood of Locomotive Engineers and Trainmen. Unironically shut this shit down

@tek Gotta convince them to become an F# or Scala department, at least :p

@bitprophet @tekOh, interesting. So I'm in a shared garage (private to my apartment building), and the access keys are little flexible stickers, presumably with some kind of tag inside. They go inside the windshield. I'm not really sure how it works yet. From what I can tell, the sensor first unlocks it with the sticker, then a motion sensor actually opens the door.

@Baa You might be able to trick them into supporting it using Pipewire + OBS. I've done some goofy stuff with that combination.

One of the neat things we do in CPU design is basically delete x86 zeroing idioms from the instruction stream.A=A xor A, things of that nature. Shortcuts to set a register to zero.We just detect them, delete the instruction, add an entry to the retire queue (so dependent ops don't get messed up), then set all the select lines to an ALU input mux to zero, causing the output to become zero. It's like a free zero register resulting from a quirk of how muxes work.

I work on the L1 data cache, so I don't get a ton of exposure to how the execution unit works, and barely any exposure to the decode/frontend units, but sometimes I learn things like this and it's like gaining eldritch knowledge

"Actually, allowing Nazis to monetize on our platform is fine. On second thought it's good actually. When you really think about it, it's very brave what we're doing, letting Nazis not only post but monetize on our platform."
