What an AI-First Programming Language Would Look Like
Current programming languages are full of syntax that AI doesn't really need. If AI is the one writing the code, why bother with brackets and commas? I explore two ways we could redesign languages for machines: either super low-level assembler or very verbose natural language. Let's look at why we need to optimize this! ;)

Engineers should start making art
Tech people spend all day inside logic, syntax, and expected outputs. Art does not work like that, and that is exactly why it can help. In this post, I talk about why you do not need talent or fancy tools to create something and rest your brain from code.

How to actually handle database transactions (and why your ORM fails at it)
Wrapping database calls in a simple try-catch block is just asking for trouble. Here is a practical look at how to handle transactions properly, avoid the dreaded ORM lost update, and keep your data actually safe.

How Docker Actually Works (No Magic, Just Linux)
Stop thinking of Docker as a mini-VM. It’s not! It’s just a normal Linux process that has been told a very elaborate series of lies. I'll show you exactly how the Linux kernel uses Namespaces and cgroups to create the "magic" of containers without any of the VM overhead.

Tech documentation is pointless (mostly)
Do you really trust documentation for your evolving codebase? Probably not fully! So why do we even write documentation or constantly complain about lack of it? Let's talk about that :D
Where MCP make sense - at least for me :)
Currently almost all MCP provided by companies are kinda pointless, but the whole concept it's not that bad. I will share with you how I started to use MCP server.
Google Apps Script is amazing for automation
Ever heard of Google Apps Script? You're missing out! This free Google tool lets you automate tasks across all Google apps with custom JS scripts, no servers needed. I'll show you how I use it to magically update my nerdiflix site every time I add a video to a YouTube playlist. It's like having your own digital assistant for all the boring stuff!

Building Your Own Web Framework - The Basics
Ever wondered what happens under the hood when you use frameworks like Symfony or Laravel? We'll start building our own framework from scratch, covering the absolute basics - how to handle HTTP requests and responses. This is the foundation that everything else builds on.

Building a Simple Search Engine That Actually Works
You don't need Elasticsearch for most projects. I built a simple search engine from scratch that tokenizes everything, stores it in your existing database, and scores results by relevance. Dead simple to understand and maintain.
Use OTP instead of email verification link
Why are we still forcing users to click annoying verification links? That flow is broken. There's a much smoother, simpler, and just-as-secure solution: Use OTP codes instead.
Become Unbannable from Your Email/Gmail
You don't own your email; you rent it. This vulnerability leaves your entire digital life at risk. Read how to seize back control of your most critical online asset by switching providers and setting up your own unbannable email server.
Compilers and VM's are easy too!
You built the parser, now let's make it fast. This guide shows you how to replace a slow interpreter with a simple compiler and Virtual Machine (VM), turning your code into efficient bytecode that executes at high speed.

In-house parsers are easy!
Ever wanted to build your own programming language? It sounds like a huge project, but I'll show you it's not as hard as you think. In this post, we'll build one from scratch, step-by-step, covering everything from the Tokenizer and Parser to a working Interpreter, with all the code in clear PHP examples.
