How the tz database works (2020)

news.ycombinator.com Unknown 2025-10-21 10:58:01

2020-11-08 The other day I ran into this timezone issue in Ruby, and that’s when I discovered the tz database for the first time. There were almost no blog posts explaining how it works, so I decided to write one myself. We’ll be using the alpine:3.12 Docker image to test things out. What is it? The tz database is a standardized collection of timezone data and rules used by most systems worldwide to handle timezone conversions. Here are the official documentation and the source code on GitH

PgEdge Goes Open Source

In November last year after nearly two decades at my previous gig, I came to the conclusion that I didn’t want to work at what seemed to be rapidly becoming an AI-focused company and moved to pgEdge where the focus is well and truly on distributed PostgreSQL and Postgres generally. Distributed databases (and particularly Postgres of course) have always been a passion of mine – even being a key topic of my master’s dissertation many years ago.

Hashed sorting is typically faster than hash tables

news.ycombinator.com Unknown 2025-10-21 21:03:21

Hashed sorting is typically faster than hash tables Problem statement: count the unique values in a large array of mostly-unique uint64s. Two standard approaches are: Insert into a hash table and return the number of entries. Sort the array, then count positions that differ from their predecessor. Hash tables win the interview ( O ( n ) O(n) O(n) vs O ( n log ⁡ n ) O(n \log n) O(nlogn)), but sorting is typically faster in a well-tuned implementation. This problem and its variants are the inn

Pure and Impure Software Engineering

Why do solo game developers tend to get into fights with big tech engineers? Why do high-profile external hires to large companies often fizzle out? Why is AI-assisted development amazing for some engineers and completely useless for others? I think it’s because some engineers are doing very different kinds of work to other engineers. Those two types of engineers often assume their counterparts are simply incompetent, but they’re really just working in different fields. Pure and impure enginee

Reshaped is now open source

About five years ago, I started Reshaped. I built it for myself, since I had a few projects in urgent need of a component library for both React and Figma. Having worked in the design systems space for over a decade, I had developed a clear sense of what a good design system should be — and what tends to go wrong in others. I noticed that no matter how trends evolve, around 80% of the web is still built on the same core design practices. So I set out to build a system that covers that 80%, whil

I grew up in a household where wasting food was frowned upon, so I always felt guilty if I didn’t go through all the leftovers in my fridge before they got spoiled.

The Apple Watch SE 3 May Be the Biggest Underdog of Apple's Entire Fall Lineup

Apple debuted a new lineup of iPhones, Apple Watches, AirPods Pros and even a brand new thinner-than-ever iPhone Air. But the real headliner (at least in this frugal girl's book), was the one I least expected: the Apple Watch SE 3. I usually overlook Apple's SE model because it lacks many of the powerhouse features of the flagship and Ultra editions, like an always-on display or temperature tracking.
