@davidgu I’ve played around with parallelizing a few thousand Chromiums for light tasks on performant machines, and that was already a hair-pulling experience. I can only imagine the pain, and insanely cool tooling, that goes into building out that infrastructure! Thanks for sharing!

[Austin McCoy @rangeroving]

@davidgu So are you all just spawning a ton of chromiums to join meetings and then piping all that video into your processing pipelines? Incredibly cool!

[Austin McCoy @rangeroving]

@davidgu One fun way I’ve tackled this on Windows before, for video-only, was opening a handle to chromium, sig-scanning for the video frame object, and copying the frames out. Was a bit of a pain, but a fun exercise

[Austin McCoy @rangeroving]

@davidgu Love it, and it is!

All fun and games until they push a patch, break your patterns, and force you to load up IDA and stare at memory for another hour 😂

I’m always shocked how many processes didn’t elevate themselves, or how many leaked info out of some side-channel

@furiouswhopper @TimTrashGoblin @vanilagy If you’re building code for others, it can be a useful tool to easily communicate potential exceptions to consumers of that code. Ie. I can make someone’s typescript light up if they don’t properly handle a returned exception, but I cannot for a thrown one

[Austin McCoy @rangeroving]

@yesadok @vanilagy That, and with a lack of error typing, it enables others to use your code without nasty surprises

[Austin McCoy @rangeroving]

@vanilagy @bartaadaniel This pattern is nice, but you get a lot of bloat code for bubbling up errors. Throw becomes dearly missed

@marclou Can’t people just create invoices and pay themselves in a loop to boost numbers?

@yacineMTB Same, that’s why I learn Leetcode with a shock collar that electrocutes me when I miss edge cases

Introducing McGemma. It’s a 1B model that runs on potatoes and always outputs 1 which corresponds to the token “French Fries, a Medium Hamburger with no Pickles, and a Shamrock Shake”

It’s hard to hype up comp sci advancements to regular people. Like “bro, you’re going to be shaking in your boots, you can find the shortest path between nodes in m·log^(2/3) n steps”

@InsiderTrackers In January 2021, thousands of low IQ apes almost ended capitalism with the GME squeeze. Not through war or terrorism, but through Discord chest beats

@StockMKTNewz Who cares about the people there. What food did they eat
