Apple provides CTFontCopyDefaultCascadeListForLanguages to get a set of fallback font names for a certain ISO language code. I want to know how much these vary.

main.swift is a quick hack to dump a JSON of all codes with the fallbacks. The test assumes Menlo 12.0 as the starting point.

output.json is the full output from running the swift hack.

Finally I used nodejs to crunch the json to buckets that have different lists of fallbacks. code is in crunch.js

buckets.json has the result of running the crunch.

Rust type conversions String, &str, Vec and &[u8]

From &str

• &str -> String has [many equally valid methods][stringh]: String::from(st), st.to_string(), st.to_owned().
  • But I suggest you stick with one of them within a single project. The major advantage of String::from is that you can use it as an argument to a map method. So instead of x.map(|s| String::from(s)) you can often use x.map(String::from).
• &str -> &[u8] is done by st.as_bytes()
• &str -> Vec<u8> is a combination of &str -> &[u8] -> Vec<u8>, i.e. st.as_bytes().to_owned()

Stream Forensics

A quick analysis of the event order for interconnected nodejs streams.

Whilst the events themselves are well documented, We wanted to find out exactly in what order events happen for interconnected streams where the readable stream ends (since this is different from reading from a never-ending input such as stdin).
