Starting to rekindle my sewing habit with some #myog (make your own gear) packing cubes.

Proud of them, besides the fact that I sewed the big one completely inside out and didn’t even realize until I had stitched the last stitch. 😅 Looks funky but I guess it’s still functional?

Persönliches Wissensmanagement - mein Buchbeitrag entsteht…

Das Team der #colearn um @jrobes sammelt wieder Beiträge der Community zu Persönlichem Wissensmanagement (PKM) für ein neues Buch.

Warum ich das jetzt schon öffentlich mache?
Weil Lernen für mich mit frühem #Sharing beginnt, es eine Lernreise ist, auf der ich im Prozess Relevanz, Perspektiven sammle und ich natürlich auf euer Feedback gespannt bin.

React-like syntax with WebComponents.

​After spending some time with Lit, I really appreciated its lightweight footprint but wasn't a fan of the class-based components. While Vue offers a great approach, I still prefer the intuitive nature of React's syntax for debugging and deterministic rendering. This led me to a challenge: could I build a UI framework using WebComponents that completely eliminates the need for transpilation?

​I have written a breakdown of the concept, the architecture, and where I want to take it. I highly invite you to take a look, check out the code, and explore the live demo.

* How it works: https://positive-intentions.com/docs/projects/dim/dim-jsx-webcomponents
* Checkout the code: https://github.com/positive-intentions/dim
* Storybook demo: https://dim.positive-intentions.com

​Please note, while the project is open-source, this is a personal exploration rather than an attempt to launch "yet another framework." It is not production-ready and is built for my own upcoming project migrations, but I am sharing it in hopes that the methodology is educational or interesting to the community.

​I would love to hear your thoughts on this approach. Feel free to reach out if you have any questions or want to discuss the implementation details.

Day 3/100 of my startup learning series.

Today’s reflection:

Startup growth is rarely linear.

Most companies move through:

Idea → MVP → Traction → Scale → Exit

And often pivot multiple times in between.

The real skill is adapting through uncertainty.

Been learning quantum on the side for months. What tripped me up wasn't the math — it was how often "canonical" circuits from papers and tutorials fail quietly. Broken Hamiltonians. Reversed bit orders. Silent API drift.

So I built a personal library where every circuit is checked against its reference output before it's listed. 50+ curated circuits across Qiskit, PennyLane, and Cirq. No signup required.

Quantum teleportation: the circuit that broke my intuition.

3 qubits. Alice shares a Bell pair with Bob, entangles her message qubit, measures, sends 2 classical bits. Bob corrects. State preserved.

No FTL. Entanglement consumed. Original destroyed — no-cloning satisfied.

What quantum protocol seemed impossible until you built it?

Two algorithms define NISQ quantum computing: VQE and QAOA.

Both variational — quantum circuit + classical optimizer. Quantum part explores an exponentially large space. Classical part steers.

VQE finds molecular energies. QAOA targets combinatorial optimization. Same structure, different objectives.

The surprise: ansatz design matters more than which optimizer you pick.

If you've tried VQE: which ansatz worked for you?

Two circuits, two lessons.

Bell State: entanglement in 2 gates. Measure both qubits — |00⟩ or |11⟩, nothing else. Perfect correlation.

Grover's Search: one oracle query flips a phase you can't observe directly. One diffusion step turns that invisible flip into a measurable amplitude boost. 2 qubits, 100% success.

What was the first quantum algorithm that clicked for you?

Tried something different with The Wealth of Nations—built a reader instead of just reading it.

Inspired by Karpathy’s idea of interacting with text using LLMs:
https://x.com/karpathy/status/1886200943471157418

My latest vibecoding experiment:
https://mrdee.in/vibecoding/vibecoding-012-wealth-of-nations-reader/

Classic texts are dense. Linear reading feels… limiting.

This is an attempt to turn reading into something more interactive, exploratory—almost conversational.

Less “consume”, more “engage”.

I published my first posts on quantum computing.

One about coming back to quantum after 20 years. The other — an audit of 50 circuits I'd built, line by line.

Most humbling find: my H₂ VQE had an incorrect Hamiltonian coefficient. The optimized energy looked plausible. I only caught it by re-deriving from second quantization.

"It gives the right answer" ≠ "it's correct."

What makes a great quantum circuit README?

After rewriting 50 READMEs, I settled on 4 layers:

1. Intuition — the physical picture, no equations
2. How it works — what each gate does to the state
3. The math — state evolution for those who want proof
4. Expected output — what you should see when you run it

Each layer for a different reader: beginner → student → physicist → experimenter.

Most READMEs I've seen only have layer 2. Which do you skip to first?

#QuantumComputing #LearningInPublic

I audited 50 quantum circuits line by line. Three bugs:

1. My H₂ VQE had a wrong Hamiltonian coefficient. The optimizer still converged. It gave the right answer. The Hamiltonian was wrong.

2. 4 PennyLane circuits broke after a NumPy update. Version pinning matters.

3. Qiskit's little-endian qubit ordering silently changes results when porting between frameworks.

Lessons: "it converges" ≠ "it's correct." Full write-up Monday.

I studied physics at Göttingen, where quantum mechanics was born (Heisenberg, Born, Jordan — 1925).

20 years in software later, the centenary year pulled me back. Tried reproducing a circuit from a paper. 15 lines of code, 3 hours of setup.

So I built QubitHub — free, browser-based. Run Qiskit, PennyLane, Cirq circuits. No install. 50 curated circuits.

Still learning. What would make this useful for you? → https://qubithub.co

Rest is part of the system!

Burnout is the #1 reason people quit their cert journey 3 months in. Schedule recovery the same way you schedule study.

The people who make it in this field aren't always the most talented.
They're the most organized and the most consistent.

What's one habit that's made the biggest difference in your cybersecurity growth? 👇

I made another ART!

I think I've got the hang of exciting features like straight lines, using colours, changing brushes, and adding text using a font (Shantell Sans). I can even make speech bubbles.

For this, my third ever comic, I was confronted with alarming new challenges that I was less prepared for. Like drawing objects and people!

Wrapped the Google Cybersecurity cert today. All 9 courses, 3 months (half the suggested timeline). While sick. Poor judgment but good timing.

Real talk: The cert is entry-level foundations. The actual learning starts now.

What I built during the program:
- Risk assessment docs (NIST CSF)
- Network hardening guides
- Python automation for log parsing
- Incident response workflows
- Full portfolio: https://github.com/kqthrs/cybersec-cert-work

Two 2-week gaps in the middle where I almost didn't restart. Momentum is fragile.

Next steps: TryHackMe, HTB, actually applying this stuff in labs. Then hunting for that first SOC analyst role.

Certificate was the permission slip. Now comes the real work.

Thanks to everyone here who answered my newbie questions along the way. Infosec community is genuinely helpful.
