Chrome: pause before redirect
// Run this in the F12 javascript console in chrome
// if a redirect happens, the page will pause
// this helps because chrome's network tab's
// "preserve log" seems to technically preserve the log
// but you can't actually LOOK at it...
// also the "replay xhr" feature does not work after reload
// even if you "preserve log".
window.addEventListener("beforeunload", function() { debugger; }, false)
//Now with less jquery
//1) go to your my-list page, and scroll to the bottom to make sure it's all loaded:
//http://www.netflix.com/browse/my-list
//2) Next, paste this in your developer tools console and hit enter:
[...document.querySelectorAll('.slider [aria-label]')].map(ele => ele.getAttribute('aria-label'))
//or use this to copy the list to your clipboard:
copy([...document.querySelectorAll('.slider [aria-label]')].map(ele => ele.getAttribute('aria-label')))

Code snippets for my blog post "The X-Files: Controlling Throughput with rate.Limiter" (http://rodaine.com/2017/05/x-files-time-rate-golang/)
// RateLimit middleware limits the throughput to h using TickerLimiter
// configured with the provided rps and burst. The request will idle
// for the passed in wait before cancelling if there is a queue.
func RateLimit(rps, burst int, wait time.Duration, h http.HandlerFunc) http.HandlerFunc {
l, _ := TickerLimiter(rps, burst)
return func(w http.ResponseWriter, r *http.Request) {

# This script will remove automatic association for all networks not listed in the whitelist
# passed as the first argument. Passwords will NOT be removed from the Keychain.

# Alternatively, you can untick "Remember networks" in Network Preferences > Wi-Fi > Advanced,

# have a long list to go through.

A Swift class to read a text file line by line, without loading the entire file into memory
// Usage:
/*
if let aStreamReader = StreamReader(path: "/path/to/file") {
defer {
aStreamReader.close()
}
while let line = aStreamReader.nextLine() {
print(line)
}

// Swift's untyped errors are a goddam PiTA. Here's the pattern I use to try to work around this.
// The goal is basically to try to guarantee that every throwing function in the app throws an
// ApplicationError instead of some unknown error type. We can't actually enforce this statically
// But by following this convention we can simplify error handling
enum ApplicationError: Error, CustomStringConvertible {
// These are application-specific errors that may need special treatment
