Never forget! Crazy to see how far it's come. And how lackluster the initial reception on HN was back then.

I got my first 99 after a 15 year break. Farming, obviously!

I’m a bootstrapped founder but hard disagree with this take. Surely it can’t be the founder taking home a healthy salary from day 1 despite the company being far away from any reve…

My daily crontab at just after midnight UTC did not run yesterday. I wrote it off as a server hiccup, but now you got me thinking it might be related to leap years…

Hetzner VPS + nginx works fine and goes a looong way. Alternatively, SourceHut pages or GitHub pages is okay too. If it’s been a while since you did any server work: https://www.da…

> It says it is free but where is the github page for it? Not sure if serious, but you do realise that free is not at all about having a GitHub page? Maxim has been working on ngin…

I never even knew this was an option, despite relying on them for well over 10 years now for well over half of my business' revenue (with 0 issues whatsoever, fwiw). Just enabled i…

Sounds like any static site generator supporting Markdown will do. - Jekyll: the OG, but requires a ruby toolchain. - Hugo: compiles to a single static binary, but you may have to …

This is inspiring to me, as I'm in a similar boat and while I'm pretty okay at my job in practical terms, I often feel as if I lack a certain mathematical foundation. May I ask how…

On most Linux distributions and when the file is mmap'd, if you run it a second time the data will still be in RAM and not have to be read from disk. This gets the runtime down to …

> I love C. You and me both. I'm also a polygot but I originally started on interpreted languages like PHP and Python. I then learned some C, which was quite frustrating before I l…

There’s an implementation in C which should run in well under 2 seconds on your M3. https://github.com/dannyvankooten/1brc

I tried the linear search by station name in my first naive approach. Using a hashmap was at least 2-3x as fast with the ~415 distinct keys in the 1BRC dataset.

You can run the bin/create-sample program from this C implementation here: https://github.com/dannyvankooten/1brc It’s just the city names + averages from the official repository u…

There are a handful of implementations in other languages already. Here’s mine in C99: https://github.com/dannyvankooten/1brc I’ve also seen versions in Rust, Go, Python, Clickhous…

Very fun challenge that nerd sniped me right away. Had to do a C version in standard C99 with POSIX threads. It[1] clocks in at just under 4 seconds on my AMD Ryzen 4800U Laptop CP…

You say database book, I say Klepmann.

Not this again. This is a number that has been doing the rounds but can be dismissed as false after less than 30 seconds of using Google and a tiny bit of brainpower. That I had to…

As a fun experiment I grabbed a list of the top 10.000 most popular domains on the internet (according to their Alexa rank) and checked each of them for compression on their HTML r…

Have been running Mailinabox since 2018 on a €5 VPS. 0 issues with email deliverability. Or anything really. It just works.

> Now, I'm one of the fortunate ones, because I didn't keep all (or even most) of my savings in GUSD and Earn; I keep most of my savings in the form of low-risk ETFs (VOO and VTI) …

Very happy to see this. Another Netherlands based project (now company) absolutely killing it with regards to databases. Wishing Ritchie and the rest of the Polars team the best of…

You asked why people talk about flying. This is a problem that can’t be solved at just a single angle. > And we certainly don’t want people driving 1000 miles instead of flying Not…
