i don’t think you understand

you spend weeks tuning hyperparameters

your grid search runs for 2 days

you finally get a +0.1% gain

you celebrate

you realize your random seed was fixed

you try a new seed

your model collapses

you try five more seeds

accuracy swings

you look at the loss curves

they look like shit

you switch to bayesian optimization

it finds the same hyperparameters

gets stuck in a local minimum

you add dropout

it underfits

you remove dropout

it overfits

you try early stopping

it stops early

you remove early stopping

it learns nothing

you read three blog posts about “superconvergence”

you try a trick

your model dies

you load checkpoint

it’s score is also shit somehow now

you open github issue

no one replies

you post on stackoverflow

they close as duplicate

you ask chatgpt

it suggests grid search or some basic shit

you realize

the only thing converging

is your will to live

i don’t think you understand

I can now, after two weeks of diligent work, verify that 2025 is not the year of the Linux desktop.

@GaryMarcus Lowering the bar for AGI only muddles progress. True AGI requires reasoning frameworks that ensure correctness, adaptability, and logical consistency. The dream of AGI will not be realized by statistical tricks but by building systems capable of true logical reasoning.

I'm trying to follow the teachings of @levelsio in 2025. Here is my first project that went live now. More projects to follow soon.

Happy to listen to feedback!

[Lagergren @lagergren]

This is great! As always, when @fbettag uses his lightspeed software development/AI skills, really professional apps suddenly start showing up. Always deployed with production quality. I wish I could do that.

[inboxrobot.de @inboxrobot]

Excited to announce that InboxRobot is now live!

To celebrate, we're giving away $10 promo codes to the first 20 people who follow and RT this post.

Make sure your DMs are open so we can send you your code.

Ready, set, go! #InboxRobot #LaunchPromo

If you use your default system Python, don’t worry about what’s in the vaccine.

[Lagergren @lagergren]

@shipilev It’s good to have a random excuse cards to pull when you get performance questions. I like “before we look at that, could you make sure you are not just measuring L2 cache misses” and “Have you check compiler doesn’t remove your payload code”. I have maybe 50 of those.

Zoom added a creepy feature: AI Companion, which produces transcripts for the meetings. Creepy how? I just got an email with a transcript of a fairly personal family meeting. Never enabled it, WTF. Dear Zoom folks, adding features nobody asked for was a Skype downfall, beware.

@tagir_valeev I don’t think we are smarter, but just like money gets compounded over time by accumulated interest, accumulared records and wisdom have made it possible to start from a significantly better initial position.

[Lagergren @lagergren]

@jawnsy Indeed. And for some things, certain tools work well and quickly gets you where you wanted to be. For other things, you may need to use something that is different. That is part of being an engineer.

[Lagergren @lagergren]

Why anyone would use Python to develop production grade, ”may never fail” software is completely beyond me.

[Lagergren @lagergren]

@saarw Yes. But it’s like crossing the river to get water, still. Do you have any good LLM cc frameworks to recommend?

[Lagergren @lagergren]

@Sharat_Chander @X I don’t even…

You HAVE to tell me if they ever describe what you did.

[Peter Lawrey @PeterLawrey]

@PeterVeentjer Performance is a functional requirement

[Lagergren @lagergren]

@mihn It grows back pretty quickly, but it’s more practical when it’s Scandinavian winter.

[Lagergren @lagergren]

Most valuable wisdom from #jcrete: apparently, I am hard to recognize without my “viking beard”.

@shipilev And the customers who ignored their other patch update change procedures and allowed a 3rd party to apply code or configuration changes to their entire fleet at one time.
