I've got an agent in a loop optimizing a renderer with the goal to minimize frame times (and tests to measure). It got times down from 88ms to 2ms and allocations down from ~150K to 500. Sounds good, right? Wrong. This is exactly why agent psychosis is a big fucking problem.

As an experiment, I rewrote the Ghostty core render state in Go, with access to identically laid out data structures as Ghostty and the exact same validation tests. I made a purposely naive renderer (simple, correct, but slow). 88ms per frame with 150,000 allocations (horrendous, lol)!

I then kickstarted a Ralph loop to bring the frame times down. I told it it can't modify input data structures or the public API or tests (they're correct), but it can do anything else it wants. It got to work.

It has worked for about 4 hours. I've spent around $350 on this experiment so far. The results?

88ms => 1.5ms
150K allocs => ~500 allocs

Incredible right? Nope.

My hand-written renderer I ported has frame times (same benchmark) of ~20us (0.020ms) and 0 allocations in the update path.

This is the problem with psychosis and lacking systems understanding. If you don't understand the system, you're going to accept that this is an incredible result. If you understand the system, you'll see better solutions immediately and can do roughly 75x better on throughput.

The people who blindly trust agent output are in the former camp. They're sheeple, overdrinking from a fountain of mediocrity.

Standard disclaimer: I use AI all the time. I like AI. The point I'm making is to not blindly accept results. Think. Analyze. Learn.

I'm struggling a little bit with inferred types in typescript.
@better_auth is good, but is not really "better-typed".. I'm sorry to say that.
There are maybe some plan to improve them?

Perché la modernità è una truffa? Più di 30 anni fa prima che nascessi, i VT320 avevano lo smooth scrolling (per pixel). Oggi, nel 2025, non c’è un terminale che lo supporti. Nessuno.

Anyway don't take too sirious the complexity thing on my latest post though.. I mean it depends and also this is ok I guess lol

[b3nab @b3nab]

nextjs, payloadcms, hono, better-auth, tailwindcss v4, shadcnui, pnpm, verdaccio, mongo, postgres, redis, minio, plausible, docker-compose, tmux, lazyvim, lazygit, kubectl, kubernetes, k0s, nginx / traefik, terraform, grafana lgtm, gitops.

Embrace complexity.

SInce I found the powerful ways to use tmux and neovim I am binge watching all videos, tutorials, articles, courses on them.

Iit's becoming quite kind of an obsession.

[b3nab @b3nab]

You are right.
Whether if you think AI will replace your job or not.. well, yes you are right.

@littlecow4 @cris_cersei A occhio non hai manco aperto un file di quelli che sono pubblici.

@Leah742 @SaltyGoat17 you should update your bio.

There are some key pieces in common between almost every production app out there:

Basic components/modules (UI library, Forms, Modals)
Auth
Payments
Analytics
Monitoring

These are the basics. On top you build the core of your business.

Raga per favore, git o github in italiano si pronunciano sempre "GHIT" o "GHITUB".

Che è sto "jit" o "jithub" !?

Types in typescript are evil and impossible to debug.
That reminds me the company behind it: Microsoft.
I rest my case, your Honor.

[b3nab @b3nab]

also embrace complexity
