I'm late to the party, but the One Billion Row Challenge (github.com/gunnarmorlin...) feels like an excellent way to dig into optimizing Rust code and learning somethings about assembly, SIMD, performance profiling, and just CPUs in general in the process, so let's take it on live! [1/3]
GitHub - gunnarmorling/1brc: 1️⃣🐝🏎️ The One Billion Row Challenge -- A fun exploration of how quickly 1B rows from a text file can be aggregated with Java

i love an internal api at work that only documents _some_ of the responses
it's a wild ride hitting it to find out what it can actually return and if the status codes even match

first time i've ever created a Rust CLI app using Clap without having to open the docs to get the format right.

i love writing about crypto crime because these dudes do this constantly
![However, the brothers' Google search history in the weeks after the theft for phrases including "how to wash crypto”, “top crypto lawyers”, “wire fraud statute / wire fraud statue [sic] of limitations”, and “prison or jail worse” suggest that perhaps the brothers had some clue that their actions could be interpreted criminally, as do the brothers' own descriptions of their plan as “sus”.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:exrxvyu6bpoym6mbnctke5tn/bafkreicpwu5pjoddgp2ovmaka2kfu6d6uc7uijrld5a4hovz5qpaqlkk5u@jpeg)

you can say what you want about Rust language design and the `unwrap()` call but if you're a company like the size of Cloudflare and writing production-critical code in Rust that powers the internet, you _probably_ shouldn't be using `unwrap()`

it's almost like making something that can take down the entire process a single short function call that is literally the easiest way to handle failure wasn't a good idea. who would have thought

#rustlang hot take: We should rename .unwrap() to .or_panic(). (And .expect() to .or_panic_with().) "Unwrap" is a terrible name for the panicking function, especially since we also have things like .unwrap_or() and .unwrap_or_default() which never panic.

my favourite tourist thing in scotland is when people take the steam train along the West Highland line to the village of Mallaig only to realise it's a small fishing village that you can explore in 10 minutes and then have to wait 2+ hours for the return leg of the journey

“AI” is just a tool like anything else. it is not a god or an end-all, be-all. if we could just stop taking every single cycle of tech bro hypeshittification seriously the world would be so much better off

i've build a lot of stuff over the years and the thing i'm most proud of?
not the robots, not the super low-latency APIs, but a silly Bluesky bot that posts Magic: the Gathering art every hour.
costs next to nothing to run on AWS and all written in Rust.
@moxarcana.com get across it

when i first started writing Rust, i thought i'd be building well-oiled performant libraries that run like with the intricacies of a Swiss watch.
what i end up making is a loud, clunky, diesel-powered monstrosity that's in some desperate need of WD40
but boy does it run well

there exists a company in glasgow that specialised in automated chemistry and AI-discovery of new molecules.
they recently opened a multi-million £££ complex to enable this.
it's funny to think that none of that would have happened if a glass syringe didn't explode in my face
