Coding is easier than ever, but thinking is still hard.

Nothing has changed.

The bottleneck is still your brain, not a model.

@FlorianGallwitz @Prof_Dr_Google @SchopenhauerOn Für was genau? Pakete auf ein Förderband legen? Pick&Place? Sorting?… Für die Anwendung im Video brauchts noch nicht mal einen Roboter, da lässt man den Tisch ein bisschen vibrieren und schon landet das Zeug auf dem Band

The dumbest person you know is being told 'you are absolutely right' by some LLM right now.

We hired a backend guy recently who didn’t know half the buzzwords.

No Saga, no CQRS, shaky on K8s. On paper, easy reject.

Then we gave him a real prod-ish bug:
sporadic 500s, p95 spikes, only on one endpoint.

He did 3 things:

1. Asked for repro + timeline. “When did it start? What changed? Any new feature release?”
2. Cut the problem space. Logs first, then metrics, then a single failing request ID.
3. Formed a hypothesis, tested it, wrote down what each result would mean.

Found it in 25 mins:
connection pool exhausted from one code path leaking retries + no timeout.

I’ll take that over memorized concepts anyday.

This is what people don't get right, companies hire for fundamentals + debugging. You can teach patterns. You can’t teach calm thinking under failure.

If you are a software engineer "experiencing some degree of mental health crisis", now hear this, because I've been coding for 50 years since the days of punched cards and I have a salutary kick in your ass to deliver.

Get over yourself. Every previous "programming is obsolete" panic has been a bust, and this one's going to be too.

The fundamental problem of mismatch between the intentions in human minds and the specifications that a computer can interpret hasn't gone away just because now you can do a lot of your programming in natural language to an LLM.

Systems are still complicated. This shit is still difficult. The need for people who specialize in bridging that gap isn't going to go away.

As usual, the answer is: upskill yourself and adapt. If a crusty old fart like me can do it, you can too.

Kubernetes is not the solution to every problem.

Most of you are running 3 containers and paying for the operational complexity of Netflix.

Sometimes a VM and systemd is the right answer.

The risk of AI for education is not students cheating in exams, it is people in general cheating themselves into believing they understand things they don’t.

Ich wünschte, dass Medien besser informieren würden. Es rollt kein Schneesturm auf Deutschland zu, sondern es gibt diesen Schneefall (blau) an einer langsam ziehenden Luftmassengrenze zwischen warmer Luft im Südwesten und kalter Luft im Nordosten. In Rot der Streifen mit Glatteisregen.

@the_npe @Oiosaila @bianca_sievert Wenn bei der Bank alle Schließfächer aufgemacht werden, hast du aber das selbe Problem. Daher am besten die Schließfächer über mehrere Standorte/Banken verteilen.

Die militärische Entführung Maduros ist mehr als ein "Regimewechsel". Trump setzt ein globales Signal: Die USA handeln wieder unilateral – ohne UN‑Mandat, ohne Rücksicht auf Kritik. Venezuela wird zum Schauplatz einer neuen Machtprojektion. 1/

Ohne zu sehr ins Detail zu gehen:

Was war euer größter und teuerster Fehler, den ihr in eurem Job jemals verursacht habt?

Ich fang an:

@ChShersh Mastering C++ takes a lifetime, so the earlier you start, the longer it will take.

You're running Kubernetes for 3 microservices and 500 users.

Run Docker Compose on a single server instead.

K8s costs you 40 hours/week in maintenance for zero business value. Your $5 VPS would handle this traffic for the next 3 years. Stop cosplaying as Google.

"Our database won't scale".

Database:
- 40GB total data
- 12 queries per second
- 0 indexes on query columns
- N+1 queries everywhere
- 200ms average query time

Solution:
- Shard across 12 databases
- Add read replicas
- Implement caching layer
- Switch to "web scale" NoSQL

Actual solution:
- Add 3 indexes
- Fix the N+1 queries
- 5ms query time
- $40/month Postgres

You don't have a scaling problem.
You have a competence problem.

Wieso heisst das eigentlich "künstliche Intelligenz" und nicht einfach "Gehirnprothese"?

Managed to get WiFi working on Linux with an unsupported WiFi card! (MT7902)

By using QEMU/KVM with PCIe passthrough and Internet sharing on the Windows VM to the tap0 interface.

You can get the WiFI connection to work on the host through this hacky method!
