Truth is 90% of backend (web) perf engineering is adding indexes and fixing N+1s. Should be app dev 101 but it's not. If you want to stand-out as an engineer at a fast-growing company: just find these and fix them.
> I am completely blown away by how amazing this is and how dramatically it impacted performance. Creating a simple index dropped database queries from ~8s to ~20ms on a production DB which containing around 20mil rows. PostgreSQL index only scans FTW.

(Incidentally, this was right after meeting @KaiserKuo when he worked there—who humbly said he once “played in a band.”).

@reasonisfun Infants don’t pick up subtle communication cues (e.g. a small nod as an acknowledgement), so in general we overdo all communication. Loud speaking, big gestures, large movements, etc.

@minakimes I’ve adopted a new head-canon on this so it’s not so bad: whole thing is literal, the kids actually hate iPhones and screens, love reading books, & they are repulsed at their parents need for devices.

@alexeyguzey fwiw this was true across all colleges in the 19th century & the reasons are more than the academic standards (getting called back to the farm was one).

@dakshgup It’s necessary to be upfront about it, that’s an easy one! On potential pitfalls of the general strategy over the long-run, some hopefully useful thoughts: . - Some people will actually select for this, but many won’t (incl many great people), so you narrow your candidate pool by.

The best programmers in the world are people you’ve never heard of, have 248 followers on this app, and the last things they tweeted were a blurry photo of Chicago in 2019 saying “fun to be in the Windy City!!” and then a retweet of @gvanrossum on some esoteric PEP.

@AndrewCurran_ He's been talking about it for some time (& not enough because everyone just keeps badgering him about LLMs). Worth a read:

@ChowdahHill A classic, written just the day before. And dated “July 5” by accident on the lower-right (I guess he may have been a bit distracted)!.

@gaghyogi49 Oh weird, assumed the same. But yeah: here's Troi as Rakal (definitely on the Romulan bridge then), and it's different.

@hahnbeeIee was starting to feel like like chill guy’s moment of fame was going to be brief but maybe he’s got a few more weeks. I do like him, we’ll see.

@KaiserKuo @chris__pc He’s clearly not an idiot but he’s always had such an abstracted and 1-dimensional view of China, historical and contemporary, that it almost feels like willful ignorance.

@mitchellh @elgeyo on-call engineers know this style of work. thrown into a unknown ruby codebase at 2:30am with no idea what code does or what Ruby is, and realizing the problem is a loop that hits MySQL 5000 times a second. not, uh, speaking from experience.

@rickasaurus Really good question. I think: they are generally trusted more & these roles have major uptime responsibilities; system design is just hard; infra & on-call work benefit most from years of seeing operational patterns. Trying to make that last part easier here at Cased actually!.

I know @AnthropicAI is getting teased for writing about obvious ML stuff as if it’s novel research—but if you don’t see the sea-change that motivates it you’re behind:. ML researchers and adjacent are not the target audience of their main content marketing anymore.

Not dunking on this, just explaining why this isn’t super interesting, nor really about SQLite, & also a little confusing in how it’s presented in the single tweet. If you’re operating on individual files, the cumulative time spent in the open() and close() syscalls adds up. On.

@KaiserKuo @chris__pc I can see that. Lacan would probably say he’s a Japanophile who has (un)consciously adopted anti-Chinese sentiment.
