Edgar Allan Poe’s "The Raven" (1845) is a masterclass in terrible AI prompting. 🐦‍⬛

The bird had a single-token output: "Nevermore."

Instead of asking, "Will I stay lonely and depressed?" (Answer: Nevermore = happy ending!), the narrator let Confirmation Bias ruin his night.

AI Evolution: Data → Chat → Agents. Next: Robots.
AI is already tackling white-collar cognitive work. Soon, Embodied AI will handle physical trades like plumbing & electrical.

I'm looking forward to it—it's the next great evolutionary leap for humanity.

Angular 21 is expected to drop Nov 20 — and it’s the Signals era.

Signal Forms are the standout: your signal model becomes the single source of truth for form state + validation.

Angular has embraced Signals. Time for developers to do the same.

Modern Angular tip ⚡
Use Signals + Services for clean state management — no NgRx needed.
.service.ts → wraps HttpClient, returns Promise (via firstValueFrom)
.state.ts → manages Signals, updates via .set/.update
Component → reads signals, no subs, no clutter

🕰️ Farewell, ts-node.
Modern Node runs .ts directly with --watch.
You served us well — enjoy your gold watch, old friend.

Angular forms debate: settled.
Reactive vs Template-Driven? Neither.
Signal Forms (Angular 21, experimental) → simpler model, typed by default, and schema-style cross-field validation—works alongside current forms.

“Premature optimization is root of all evil.”

Write clean, object-oriented, maintainable code first.
Measure to find real hot paths.
Then optimize only where it matters.
Clean → Measure → Optimize.

If there’s no code, there are no bugs.

That’s the beauty of reactive programming: change state, and everything else flows.

Angular showed this with Observables, and now takes it further with Signals + computed—making apps simpler, faster, and more predictable.

Software obeys the second law of thermodynamics. Entropy means disorder—left alone, systems drift toward chaos. Every change nudges code toward complexity; only steady, intentional care keeps a codebase healthy. Start strong or it will only get worse. #CleanCode #TechDebt

[Joseph Genchik @jgenchik]

We’re in Angular’s 3rd revolution: Signals-first.
#1 was the AngularJS→Angular2 rewrite;
#2 was Ivy (quiet but huge);
#3 shifts reactivity to Signals.
Keep Observables at IO edges, model state with Signals. Forms/Router/HTTP are next.

TypeScript tip: prefer unknown over any.
any turns off type safety, while unknown forces you to check before use.
It’s a small change that helps catch bugs early and keeps your codebase reliable.

How has AI changed the way you code?

The first time I saw an AI code assistant generate an entire app from a single prompt, it felt like science fiction. 🚀
But here’s what I’ve learned… 🧵

[Joseph Genchik @jgenchik]

The future belongs to developers who collaborate with AI—thinking critically, asking the right questions, and ensuring quality every step of the way.

We’re not doing less work. We’re doing different work.

Google did not post my photos of the Vienna, Austria, Holocaust Memorial on Google Maps because it "[...] more likely to receive content that violates Google's policies."
Hey, Google... are you denying the holocaust or pandering to those who do?
