Has AI killed unit tests yet? I don’t think so.

Ok is time to rebuild it in rust

I've been using fable 5.2 for the last 28 minutes, here are my thoughts 🧵
Introducing Claude Fable 5.2 and Claude Mythos 5.2, designed to tackle the most daunting technical challenges. They’re capable collaborators on ambitious projects in many fields, and show improvements in areas like coding, reasoning, and vision.

can't believe I've actually bought the dip for once 🤑
JUST IN: $1,000,000,000,000 added to the US stock market at open.

Super safe btw, just a mass shooting here and there: tvpworld.com/96370580/krakow…
🇵🇱 Warsaw is Poland's biggest city and it is completely safe at 1am at night No violent junkies, no drug dealers, no street thugs hanging around harassing women (and men), no pickpockets (nor in the day btw) No shady people hanging around the train and metro stations Just people living chill together and police enforcing safety You know like we used to in Western Europe? There's a lot to learn from Poland

90k LoC could easily be a PR today.
Hot take: You can vibe-code a small app. You can't vibe-maintain a 90K+ line codebase. No chance.

This should be a reminder for all intelligent people out there: if you make being hyperrational your entire identity and you don't keep your ego in check (despite your successes), this is what will happen. You think you'll live in this very exclusive, enlightened bubble, where you have all the answers anybody else is too stupid to see. While on the other side, you become ever more vulnerable to confirmation bias, because your entire identity is built on the fact that you can't possibly be wrong or fooled. You shield yourself from constructive criticism. You start to distance yourself from people who were once close, because all of a sudden they're not smart enough for you anymore. You reduce yourself to this bitter, paranoid, and conspiracist self. Ever so "right", and ever so lonely.
if you ever wondered why your IQ is so low check which toothpaste youre using love this app

Those proposed AI moratorium are essentially the "ban nuclear power plants" of this century. Uninformed fear-driven policy that will set humanity back at least a few decades. It's sad to see, probably can't be stopped at this point.

I admit that I completely broke down today. I cried uncontrollably. I couldn’t hold myself together after witnessing what I saw with my own eyes. Today, we went to film a journalistic report inside the displacement tents along the seashore. I swear, what we witnessed was beyond what any human being should have to endure. I saw men crying bitterly. Men I had never seen cry when they lost their children or when their homes were destroyed. Today, I saw them crying because they were powerless to do the simplest thing: protect their children from the water and the cold. We spoke to families who told us they had spent the entire night carrying their children in their arms after floodwater covered the floors of their tents and soaked their mattresses. They couldn’t find a single dry place to put their children. They couldn’t even give them a few hours of sleep. I saw children no older than five, without proper clothes to protect them from the cold, without heating, and without a dry place to sleep. Children shivering inside tents that cannot keep out the rain, protect them from the wind, or provide even the most basic sense of safety. What more must happen for this world to act? How much more suffering must people endure before someone remembers that they are human beings? I am sick of this world. I am sick of its hypocrisy and empty slogans. To hell with a world that talks endlessly about human rights while leaving children to drown inside their tents. To hell with everyone who has witnessed this suffering and chosen silence, and to hell with the governments and institutions that have the power to act but continue to turn their backs on us.

So I have a theory: AI is cooking ppl brain so much that we forgot how to do infra. So now there’s this entire new market in which ppl sell you this thin level of abstraction promising “simple” provision, slap the copy “for AI agents” on it and sell it to you at $20/month. 🤯

You have to explain the ICP of those AI sandbox. Dafuq is this, a terraform file as a service?

Wild that I'm now essentially opening the Codex (ChatGPT?) app only to use my banked resets. They kinda killed it when they decided to merge it with the normie's ChatGPT app. Not an easy fit to alienate both user groups (devs and normies) in a single move. 🥇

Writing production code might be the least valuable thing AI coding agents do. If you're judging usefulness by how well they write production-ready™ code, you're kinda missing the point.

She's right and this is a REAL issue, the "smarter" the model the higher the risk of it going in an overthinking spiral that leads to terrible code. You need to read "some" of the code still.
My friend asked me to use their claude account and just "try" it, just once, opus 5.5 on xhigh effort. i would be "amazed". fine, i gave in. I have it one simple task. refactor some of my code that was manged sql in services and generic repos i created into a simple clean slice controller -> service -> repo -> dao I gave it all it needed, i gave it even reference code from my other repos on how the architecture should be, i even started in `plan` mode. 45 mins later (i could have done this in 20), it created the result, it was fucking.... AWFUL! It basically took my service layer, and shoved ALL service code into the DAO itself. when i questioned it, it admitted that it is not a real DAO. it said > Your rules say to keep structure when moving code I have no such rules, i installed this app TODAY > I fixed each complaint and never checked the whole yeh, no fucking shit. It knew that it was bad design but did it anyway. This is exactly my point here. if you do not CHECK the code it makes deeply and follow it through in an IDE or something, you can be committing shit. If you do not understand the code, do not understand the architecture, etc... it can work just fine. these vibecoders have no idea. Not only that, but I have 2 daos one for in memory, one for sqlite. the service layer that should be responsable for taking the SearchParams, splitting it up, parsing, aggigating data, creating the DTO, etc... was REPEATED exactly, in BOTH the sqlite DAO and the in memory DAO instead of putting it in the service layer once and then the DAO just deals with getting data. so there, all those AI bros who try convince me to "just try it once", I did, It was shit. Oh and it decided to keep the whole of the old `/store` code and mix it for zero reason. Remember, Opus 5.5 said this was COMPLETE and WORKING. Yes it worked, but it also butt fucked my codebase SO fucking hard that i reverted every single change it made and did it myself in about the same time as it did it all but now it's actually correct. Oh and it decided instead of using a self join, to create a whole complex `BuildInteractionIndex`
