New article: Inside Helm - How Charts, Releases, and State Work in Kubernetes 🩷

We all love helm install - but few actually know what happens behind the scenes.

Helm isn’t just a YAML renderer. It’s a stateful release manager that:
• renders and applies manifests,
• tracks releases inside your cluster,
• stores state as Secrets or ConfigMaps,
• and handles upgrades with a 3-way merge.

Let’s open the black box of Helm.

My new video is live! 🔥

Ever wished AWS could just tell you why nothing works? 😅

Meet Amazon Q - the AI assistant built into AWS that finally speaks cloud like we do. 🙃

In this video, I break down what Amazon Q really is, how it helps with IAM, Lambda, and VPC configs, and why it actually matters for every DevOps engineer who’s ever yelled at the console. ⚡️

🎥 Watch here → https://youtu.be/4Ke8eQWKfzs

What’s the one AWS thing you wish an AI could fix for you? 👇

Mobile Tester Agent - AI that runs your Android tests for you.

It clicks, swipes, and validates app flows through ADB - while chatting in plain English.

Think of it as your new QA teammate (that never sleeps ).

What’s inside:
⚙️ Core Agent (Kotlin + Koog)
🖥️ Frontend Dashboard
📱 Demo app to play with

An interesting open-source step toward AI-driven mobile testing.

When Python runs faster than C++ - meet Codon.

Codon is a high-performance Python compiler that transforms your scripts into native machine code, running 10–100× faster than CPython.

No GIL.
Real multithreading.
Even GPU acceleration.
And the best part?
It keeps the same Python syntax - just turbo mode engaged. 🐍💨

If performance ever held your Python back - Codon changes the game.

Ever feel like you’ve spent more time in AWS than on vacation? Same 😂☁️

That’s the real DevOps life - juggling cloud, AI, and chaos like a queen 👑💻

Do your containers ever behave like cats - sleep all day and create chaos at night?

Some services feel exactly like that: almost no traffic, but still running 24/7 and eating resources.

I found Sablier, a simple tool that pauses idle containers and starts them again on the first request.
Basically: “I’ll nap here. Call me when you need me.” 😌

It works with Docker, Kubernetes, Traefik, Nginx, Caddy and Envoy, so it fits into most setups without extra complexity.

Great for homelabs, side projects, demo environments or anything that doesn’t need to stay running all the time.

Nice way to keep the cluster lighter and cleaner.

A beautiful little AI demo worth your time.

A developer built a tiny neural network trained on MNIST - and turned it into a fully interactive 3D visualization that shows how the model “thinks” in real time.

You draw a digit, and you immediately see how activations move through the layers, which connections light up, and how the network arrives at its prediction.

Simple, visual, and surprisingly insightful - especially for anyone learning or teaching ML.

Ever look at your life and think “wtf is this?” 🤪

An app called Perfice can audit your week - and the verdict can be brutal:

“You’re not cursed - you’re just running on 3 hours of sleep and pure delusion.”

Perfice is a local-first, open-source self-tracking tool that helps you see how your sleep, mood, habits and daily chaos actually connect.

Key things about it:
All analytics run locally - no random cloud sucking up your data
You can track whatever matters (sleep, mood, food, focus, etc.)
Data can be exported (CSV / JSON) if you want to plug it into your own stack
Feels more like a tool for engineers than another generic “wellness” app

For anyone into quantified self, self-hosting, or just tired of guessing why they feel exhausted all the time, Perfice looks like a solid option.

AI in the browser is moving fast - and it’s starting to do the work for you, not just auto-complete text.

Fuji-Web is an open-source web agent that can take a task you type and execute it directly on a website:

clicks buttons and navigates pages
fills forms and inputs
extracts or finds information on the page
explains every action as it goes

Everything runs inside your browser, powered by your own OpenAI or Anthropic API key.

The team is already working on workflow automation, saved actions, and a built-in knowledge base.

Found something unfairly useful and of course I’m sharing it here 😊

A GitHub repository with almost 100 free AI & LLM courses and guides - including Stanford lectures, RAG tutorials, LLM architecture breakdowns, interview prep resources, and practical notebooks.

If you’re learning AI or leveling up your LLM skills, this collection is basically a full roadmap in one place:

Running Android on Linux is no longer a niche hack - it’s becoming a practical part of modern workflows.

redroid (Remote-Android) is an open-source solution that lets you run full Android instances on a Linux host using Docker, Podman or Kubernetes.

It’s designed for:
device virtualization
cloud gaming
large-scale automated testing
CI pipelines and device farms

Supported architectures: ARM64 + AMD64
Android versions: 8.1 → 16

Display settings, GPU modes, and GMS integration (Open GApps / MicroG) are all configurable.

Documentation also covers required kernel modules and deployment specifics across Linux distributions.

Wanna one day smell The Witcher 3?

Velen swamps, ghoul breath, damp drowner caves, Geralt’s potions…🔥

A small neurotech team just used focused ultrasound on the olfactory bulb to trigger 4 scent-like sensations in the brain (fresh air, trash, ozone, campfire) - no nose involved.

It’s a tiny early experiment, but if this evolves, VR and gaming might literally get a smell slider.

Proton rolled out Proton Sheets - a privacy-first alternative to Google Sheets.

Gemini: “Show me your data?”
You: “No.”
Sheets: “Also no, but in Swiss.” 🇨🇭🔐

End-to-end encryption, zero-knowledge architecture, encrypted metadata - even file names stay private.

You open a spreadsheet - and Big Tech immediately cries. Because for the first time in a long time, your data actually belongs to you.

Privacy 1 : 0 AI

Looking for developer tools that don’t require your credit card, your personal data, or your last bit of sanity? 😇

I found a fantastic resource: Free for Developers - a curated list of hosting, databases, APIs, CDNs, domains, monitoring tools, and more.
All legit. All actually free. All neatly organized so you don’t cry in the docs or in the billing dashboard.

It’s open-source and community-maintained on GitHub.

Want to “hack a bank” - legally? 😇
Here’s your chance.

A deliberately vulnerable banking web app on GitHub, packed with 40+ intentional security flaws, created specifically for training.

A perfect playground for:
• cybersecurity engineers
• pentesters
• DevSecOps
• developers learning to think like attackers (and code like defenders)

Safe, isolated, educational - and way more fun than another theory course.
