Understanding Async Programming

Async programming, short for asynchronous programming, is one of those concepts that might sound intimidating at first but becomes surprisingly intuitive once you understand the problem it is trying to solve. And that problem is mostly waiting. Modern applications spend a lot of time waiting for things to happen. They wait for APIs to respond, databases to return queries, files to be read or wri...

Cutting Cloud Costs with a Few Habits

The Silent Budget Killer Cloud bills creep up. You start with a small instance, a managed database, and a bucket. A year later, you're paying for resources you forgot existed. The worst part? Most of that waste is avoidable with a few simple habits. I've been there. After a particularly painful invoice, I made a checklist of practices that now keep my cloud spending in check. Here's wh...

Authentication done right: JWT, sessions, and OAuth explained — Like a Marvel superhero assembling the team

The Quest Begins (The "Why") I still remember the first time I tried to add login to a side‑project. I’d read a tutorial that said “just store a token in localStorage and you’re good,” slapped together a few fetch calls, and called it a day. A week later I got an email from a user: “Hey, I can’t log out, and someone else seems to be using my account.” My heart sank. I realized I’d bolte...

Programming for Cybersecurity: What You Actually Need to Know

When I first got interested in cybersecurity, I thought it was all about tools. Nmap, Metasploit, Wireshark, Burp Suite. I downloaded them all, watched tutorials, and felt like a hacker. But the first time I tried to customize a scan or parse a weird log file, I hit a wall. I didn't know how to code. And in cybersecurity, that's like trying to be a chef without knowing how to use a knife. This a...

Can you actually access a variable via its string name at runtime?

That's to continue from my other post. I would need to either place a text string like "{{ user.name }} is the user's name." inside a template (and have the page correctly say "MeekHat is the user's name." Or I would split it along the curly braces. But I still need to find out the field "name" of the "user" variable. And all I have is the original string lo...

Python Iteration Protocol: Iterables vs Iterators

Python separates the `Iterable` and `Iterator` protocols to support multiple independent cursors and lazy streaming computation. It achieves O(1) memory usage at the cost of random access and replayability.If you use a Python list to load a 100 GB log file all at once, the process will quickly run out of memory (OOM) and the operating system will terminate it. Switch the code to stream the file th...
