Most currencies have a special pattern that printers are programmed to detect and refuse to print. Since illegal gun part designs can’t be forced to include a marker declaring that they’re gun parts, a 3d printer would have to 1) know what a gun is, 2) know how a gun works, 3) be able to tell whether any particular shape could be used as part of a gun, and 4) be able to tell whether any particular shape could be cut and reassembled into a shape that could be used as part of a gun

The primary reasoning I’ve heard is that it’s easier to do arithmetic with numbers that are factors of your numeral base and 12 has more factors than 10 (1, 2, 3, 4, 6, 12 vs. 1, 2, 5, 10)

Base 12 seems a little impractical to me since humans have 10 fingers, which makes base 10 easier to teach to children, but it’s a matter of opinion i guess

τ is equal to 2π, which allows the formula for the circumference of a circle to be written more concisely (τr vs. 2πr or πd) but complicates most other places where π is used, like in the area of a circle (τr^2/2 vs. πr^2)

Maybe browsers could be configured to automatically accept the first certificate they see for a given .internal domain, and then raise a warning if it ever changes, probably with a special banner to teach the user what an .internal name means the first time they see one

I know about the CGI standard, but mine does things a little differently (executable files don’t just render pages but also handle logging, access control, etc. when put in special positions within a directory), so I still think it was worth the afternoon i spent making it.

my website’s backend is made with bash, it calls make for every request and it probably has hundreds of remote arbitrary code execution bugs that will get me pwned someday, it’s great

edit: to clarify, it uses a rust program i made to expose the bash scripts as http endpoints, i’m not crazy enough to implement http in bash

it behaves like a static file server, but if a file has the others-execute permission bit set it executes the file instead of reading it

it’s surprisingly nice for prototyping since you can just write a cli program and it’s automatically available over http too
