Why Use Postgres?
Five years ago I wrote a post that got some good attention on why you should use Postgres. Almost a year later I added a bunch of things I missed. Many of those items bear repeating, and I’ll recap a few of those in the latter half of this post. But in the last 4-5 years there’s been a lot of improvements and more…

Show HN: Sorting Two Metric Tons of Lego
One of my uncles cursed me with the LEGO bug, when I was 6 he gave me his collection because he was going to university. My uncle and I are relatively close in age, my dad was the eldest of 8 children and he is the youngest. So, for many years I did nothing but play with lego, build all kinds of machinery and in…

There is no pass by reference in Go

Why don't schools teach debugging? (2014)
In the fall of 2000, I took my first engineering class: ECE 352 , an entry-level digital design class for first-year computer engineers. It was standing room only, filled with waitlisted students who would find seats later in the semester as people dropped out. We had been warned in orientation that half of us…

Glob Matching Can Be Simple and Fast Too
Here’s a straightforward benchmark. Time how long it takes to run ls ( a* ) n b in a directory with a single file named a 100 , compared to running ls | grep ( a.* ) n b . Superscripts denote string repetition and parentheses are for grouping only, so that when n is 3, we’re running ls a*a*a*b in a directory…

Reproducing Go binaries byte by byte
Fully reproducible builds are important because they bridge the gap between auditable open source and convenient binary artifacts. Technologies like TUF and Binary Transparency provide accountability for what binaries are shipped to users, but that’s of limited utility if there is no way (short of reverse engineering)…
