Ask HN: How do you handle release notes for multiple audiences?
For those of you who ship often, when you release updates, do you typically write one set of release notes, or do you end up rewriting them for different audiences? For example: • technical version for developers • simplified version for end users • something more high-level for stakeholders etc… In my current position I’ve […]
VPN location claims don’t match real traffic exits
In a large-scale analysis of 20 popular VPNs, IPinfo found that 17 of those VPNs exit traffic from different countries than they claim. Some claim 100+ countries, but many of them point to the same handful of physical data centers in the US or Europe. That means the majority of VPN providers we analyzed don’t […]
Dick Van Dyke turns 100
All Hollywood stars grow old and die except perhaps one – Dick Van Dyke – who turns 100 today. The real world Peter Pan who used to trip over the ottoman on The Dick Van Dyke Show is still standing. The man who impersonated a wind-up toy in Chitty Chitty Bang Bang hasn’t wound down […]

Fast, Memory-Efficient Hash Table in Java: Borrowing the Best Ideas
One day, I ran into SwissTable—the kind of design that makes you squint, grin, and immediately regret every naive linear-probing table you’ve ever shipped. This post is the story of how I tried to bring that same “why is this so fast?” feeling into Java. It’s part deep dive, part engineering diary, and part cautionary […]
I tried Gleam for Advent of Code
I do Advent of Code every year. For the last seven years, including this one, I have managed to get all the stars. I do not say that to brag. I say it because it explains why I keep coming back. It is one of the few tech traditions I never get bored of, even […]
Playing Santa Does Things to a Man. What It Did to Bob Rutan Was Even Stranger
Aaron Richter Santa Claus was nursing a beer at an uptown dive bar. The neighborhood was gentrifying, and management seemed eager to accommodate—there was scented soap in the bathroom and twenty-two-dollar lobster rolls. But the place couldn’t outrun the regulars. They drank tumblers of Irish whiskey filled to the brim, illicit pours they secured with […]
Ask HN: How can I get better at using AI for programming?
I’ve been working on a personal project recently, rewriting an old jQuery + Django project into SvelteKit. The main work is translating the UI templates into idiomatic SvelteKit while maintaining the original styling. This includes things like using semantic HTML instead of div-spamming, not wrapping divs in divs in divs, and replacing bootstrap with minimal […]
Annual Production of 1/72 (22mm) scale plastic soldiers, 1958-2025
It is often said that this hobby is currently going through a ‘Golden Age’, with new sets appearing all the time and a record number of manufacturers satisfying demand. So we thought it would be interesting to actually quantify that, and let the statistics show just how the hobby has fared over the few decades […]
