First weeks? Fast progress. Now? Slow grind, complex problems, new algorithms.
Hard truth: it's not that you're dumb - you just don’t know pattern (yet).
LeetCode ≠ real-world work (but helps)
Burnout is real
Solid way to grow fast
Still climbing that ladder.

Even in chaos, there is direction.
I’ve been watching a Rössler attractor and drew it in #Python.
No randomness. Fully deterministic.
Yet the path never repeats.
• Chaos follows rules
• A non-linear path still has direction
• Deviations ≠ being lost

🎮 How multiplayer really works (in 20 seconds):
Your movement isn’t just “moving a cube.”
It’s a whole distributed system:
1️⃣ Client sends input
2️⃣ Server calculates the real position
3️⃣ Server sends replication
4️⃣ Client predicts + corrects based on server truth

Google doesn’t check the whole index when you type a nickname.
It first uses a Bloom filter a small structure that quickly tells:
- the nickname is definitely not in the data
- it might be there, and the system should run a real lookup.

Cloudflare went down and the internet felt it.
The reason? Not an attack, not BGP… just a config file that suddenly doubled in size and broke routing.
The biggest outages often come from the smallest changes.
A solid reminder for anyone building scalable systems.

Gave a talk on how to stay relevant as a developer in 2025 💻
We talked about:
- Real job market trends
- What skills are actually hot
- Why “just coding” isn’t enough anymore
Key takeaway: tech changes fast, but curiosity ages well 🚀

🔥 Montenegro is on fire. IT is helping.
Today we held volunteer calls to create app to coordinate help during the forest fires:
📍 Live Location of volunteers + airplane
🔥 Reporting fire spots with photos and coordinates
🗺 Shared map with safe routes
Technology isn’t just about business.

25 years later… I just took a final exam at MIT! 😅
Finished 6.00.1x: Intro to CS & Python on edX. Didn’t get 100%. Took it last minute, late at night - classic!
Now waiting for the certificate and signed up for 6.00.2x starting in November.

Tried out the Amazon Q Agents + MCP workshop by AWS:
🔹 Agents = goal-driven LLMs that take real actions
🔹 MCP = secure connectors to APIs, DBs, services
Together, they automate real business logic inside AWS.
Impressive step toward production AI.

Took part in a live coding session with Max Kless and Jan-Niklas Wortmann where we built an MCP server from scratch using TypeScript and integrated it with @jetbrains.com IDEs. Great experience and a fun way to explore how AI can enhance the dev workflow!

Do you consider yourself a young .NET developer?
Just a reminder: Microsoft turned 50 this year 🙉
And .NET is already over 20 😅
So if you started coding in .NET after .NET Framework 4.0 - you're basically a youngster 😅
