Writing UTC-Friendly Datetime Code in Python

Thu Oct 2 2025

You’ve written Python code that works fine on your machine. But when your app runs in production across servers in different regions, the logs don’t line up. An event that happened at 10 AM UTC looks like it happened at 3 AM on one server and 6 PM on another.  More

Handling Time Zones in Python: Avoiding Naive Datetime Bugs

Thu Oct 2 2025

Imagine you’re building an event scheduling app. A user in New York creates a meeting for 3 PM. That timestamp is stored in your database. When a colleague in London opens the app, they see the event at 3 PM London time instead of the correct converted time.  More

Sun Sept 28 2025

It’s 2 AM, production alarms are firing, and every attempt to read or write to S3 comes back with "AccessDenied". But this isn’t your ordinary bucket policy issue. This time, the bucket has SSE-KMS (Server-Side Encryption with AWS KMS) enabled — and the missing link is key permissions. More

The Alternative Filing System: Open Addressing Explained

Sun Sept 28 2025

Timothy's mastery of the chaining cabinet had served him well, but his curiosity about alternative systems led him to discover a completely different approach hidden in the library's eastern wing.

The Day I Stopped Repeating Myself in Python

Sat Sept 20 2025

For years, I was a code copier. A control-C, control-V programmer, stuck in a loop of repetition. I'd build a function, and then I'd build another one that did something similar. Maybe I needed to time how long a function ran, or maybe I needed to log its inputs and outputs. So I'd copy a few lines of code from a previous project, paste them into my new function, and hope for the best.  More

Demystifying Python Decorators, Part 2: The Pythonic Way and Advanced Usage
