@jhartikainen Another phenomenon I've noticed: everybody thinks their own AI generated code is great, but everybody else's AI generated code is "too long unreadable cringe slop"
The really humbling part is coming back to your own AI generated code 3 months later and seeing it as slop

New post: Why I don't use AI coding tools, with scientific research papers to back up my claims.

Good read from an excellent writer 👇
I can't say I agree 100%, but there's a lot of good thoughts in here

@chinedu_10 I'm genuinely surprised when I have to explain to people that indexes slow down writes
Seems like the most obvious thing. For one thing, if indexes speed up reads, the natural follow up question is "why don't you just index everything by default?"
English
I have another take.
Most devs who don’t read books won’t learn this unless they get curious enough to check why their writes are suddenly slow in prod (p50/p95/p99).
A lot of people never work on systems with enough traffic for slow writes to become obvious, so they never go looking.
The ones who do learn it are usually the ones who investigate and realize “OMG… too many indexes have a tradeoff too” 😂
Austin@IamAroke
Indexes don't just speed up reads. They slow down writes. Every index you add is a tradeoff. Most developers only learn this in production.

@a_hafez12 You think this is a joke. I still remember a friend of mine put together a static site with over 200 direct dependencies because he was experimenting with creating a "best practices starter" 🤦♂️
Sometimes I wish I did iOS dev

Here’s my 12 million LoC Hello World
Bashmohandes Mazen - بشمهندس مازن@BashmohandesM
هجوم جديد بسبب مكتبة في npm اعتقد جه الوقت ان استخدام المكاتب يقل، و بمساعدة ال ai حرفيا يتم استبدالها بكود من الصفر… الكلام ده ممكن يتحقق لجزء كبير من المكاتب اللي موجودة في npm… لان معظمها بتحل مشاكل صغيرة بس طبعا ده ليه ميزات و عيوب

@jpschroeder @KaiXCreator I once had a junior dev try to tell me that writing code was the hard part of running a biz... 🤦♂️
English
@KaiXCreator People who think the hard part of being a founder is the code probably shouldn’t be founders.

@davidrgoldberg Santander Work Cafe in Coconut Grove. Can't beat free coffee.
English
Best cafes or coffee shops to work out of in Miami?

@GregorySchier Same. Before fatherhood I'd drink 1-2x/week, watch tv shows most nights, etc. After fatherhood maybe drink 5x/year and only TV show I've watched is Fubar
English
Having a kid made me:
- stop alcohol
- stop watching tv
- stop binging YouTube
- start another company
I'm not even against these things (had a beer the other day) but my priorities are now incredibly clear.

Pro tip for mothers day: stop ordering from 1-800-Flowers or the other big aggregators. They're slow, incredibly overpriced, and their service sucks.
Order from a local florist on DoorDash or similar
50% cheaper, delivered in a couple of hours

@swyxio Nice! Any of your portcos need dev or devrel help?
English
@DanShappir This is a surprisingly good metaphor
The other side of the metaphor: people thought serverless would replace servers on the basis of cost and availability, but turns out 1) serverless is too complex, 2) cold starts, 3) serverless doesn't solve any real problems
English
Agents are to developers kind of as serverless is to servers: you can get as much or as little as you need, on demand, as long as you're willing to pay for it.

We're so stoked to move from .ai to dreambase.com!
@rob and the team at @snagged were insanely fast and got us the deal we needed. Highly recommend.

@a_hafez12 Yeah I agree people are more concerned about GitHub than the US economy... I'm the opposite. Entire industries have been in "extend and pretend" mode since 2022 or more - airlines not even the worst of it.
English
On the contrary, people aren’t panicking a fraction of what they should about the energy crisis.
It’s not speculation, the damage is done, yet the majority seem to be happy to bury their heads in the sand.
Hafez@a_hafez12
Hot take: the GitHub situation isn’t that bad in its current state, it’s the direction that’s worrying.

@SamyDindane What sort of moralizing are you seeing? I use ChatGPT, my only complaint is that it is a bit midwit; but it's trained on Reddit so that's just a consequence of the training data
English
Considering switch my main LLM from ChatGPT to Claude.
Years of great output, but the holier-than-thou moralizing is getting annoying.
Claude doesn't do that.
Who else faces this with GPT?

Mongoose Studio v0.4.1 now has a bindIp option to restrict connections.
Set to only allow localhost by default based on `req.ip` for Express
No more worrying about coffee shop WiFi
