The career of a software/infrastructure engineer is mostly doing boring things and asking ridiculous questions in hopes of making order out of chaos and making light work of something. That’s when that satisfactory smile is put on our faces. Always a delight to read such blog
Debugging infra at scale is rarely about one big “aha” moment. In our latest engineering blog post, Brian Stack ( https://t.co/Sy02lHeKRK) recounts his journey through the "Kubernetes hypercube of bad vibes" and how one small flag change led to a significant impact.

The dirty little secret of edtech: the biggest names don’t actually care if you learn anything. As co-founder of Udemy, it is something I reckon with every day… Duolingo - edtech’s only decacorn, worth $14B. Brilliant app, addictive product, and great for motivation. But let’s

You’ve likely come across terms like HTTP, TCP, IP, and TLS, or heard discussions about latency and bandwidth. But what do these concepts really mean, and how do they work together? I covered that in my latest post on the TCP/IP protocol, where I dive into how the internet

Last week, I wrote several articles on secure web sessions and building a session manager in Go. If you’re curious about how web sessions work, how to secure them, or just want to read some Go code—give it a read!

Rewrite in Go is the new rewrite in Rust. Developers just can’t resist a good rewrite, can we?

Bad coders can now use AI: - To bid on projects - To build a fake portfolio - To write fake blog posts - To write fake OS projects As much as I love the productivity boost AI gives me, I worry that the overall quality of the software we use every day is going to decline.

Yesterday I helped a friend with their startup's single server going down after an update. Turned out the contractor's AI generated code loads over 12k records from the database and presents them in JSON responses (on every request). The pool of bad software contractors is
We're about to have a crazy amount of AI written vulnerable software out there, and it's going to be a mess. What a time to get into software security.

A few weeks ago, I experimented with building a Laravel-like, type-safe, & concurrent-safe DI container in Go. I always thought this was only possible in dynamic languages like PHP, but thanks to generics & reflection, I made it work! Read more about it in the first comment:

People are realizing the safe and secure path is now the least safe and secure (always has been). Become a deep generalist and do many things. Those who can handle the most uncertainty win.

Diving into Go 1.24 release notes last night & spotted a major performance boost from the new map rewrite. Love that Go's runtime is written in Go so I had to peek at the code. What a total masterpiece! I wrote about it in a blog post 👇
