"Every augmentation is also an amputation." – McLuhan https://driverlesscrocodile.com/technology/neal-stephenson-o...

There's a reason Spotify might force shuffle play on the free tier. It isn't solely to annoy you into upgrading. Royalties are 2x - 5x higher for interactive vs non-interactive str…

Are human rights concerns running cover for more straightforward financial interests here? Norway and Saudi Arabia are both petrostates with large sovereign wealth funds.

> I believe the bounding box has to fit all the possible ascenders and descenders etc., so the em-height is proportioned within the box to whatever the highest and lowest marks in …

nginx validates hostnames per the spec, and to your question specifically it rejects requests that would put a slash in $host: https://github.com/nginx/nginx/blob/b6e7eb0f5792d7a52…

This nginx local dev config snippet is one-and-done: # Proxy to a backend server based on the hostname. if (-d vhosts/$host) { proxy_pass http://unix:vhosts/$host/server.sock; brea…

These are neat. I'm reminded of Claude Mellan's face of Christ from 1649. This also uses a single continuous line, but he was carving the line by hand into steel! https://www.galle…

Gleick's "Chaos" got me sent to the principal's office in high school. I went crazy for fractals. Unfortunately all I had at home was an IBM PC XT. Mandelbrot set renderings were a…

Thank you!

Who was the first person to propose FFTs for faster polynomial multiplication? Got curious about this recently. I’m not great at citation tracing, but did make it back to this 1995…

> Sure, but how often do you need to touch that config? More often than I’d like! tmux config has broken backwards compatibility on me multiple times over the years. This is fine f…

HTML can be described by a context-free grammar [0], but not by a regular grammar [1]. If a language can be described by a regular grammar, you can parse it with a regular expressi…

This idea was used to great effect in Matt Might’s “Parsing with Derivatives” paper [0]! And it featured prominently in the Compilers class he taught at the University of Utah. [0]…

Lol okay man. Maybe if you're running FreeBSD 4.2 or HP-UX or some BSD derivative from the 90s. All unix systems from about 2000 on will honor unix domain socket permissions.

Like you, we use pre-signed S3 upload urls. From there we use Transloadit [0] to crop and sanitize and convert and generate thumbnails. Transloadit is basically ImageMagick-as-a-Se…

You do realize D-Bus also uses SO_PEERCRED right? And transitively polkit, systemd, and everything in that ecosystem. https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/dbus/..…

What do you mean by "great ideas and great implementation / bad execution and bad interface." Is this a plumbing vs porcelain distinction?

I like s6! One of the key differences here is that s6-sudo builds on, rather than replaces, the standard unix permissions model. s6-sudod listens on a unix domain socket. Unix doma…

run0 has already been exploited: https://twitter.com/hackerfantastic/status/17854955875146385... There will be plenty more where that came from. Yet another terrible idea and terri…
