Babel - a JavaScript transpiler
Might be good for compiling ES6 to ES5 for all those mod cons.
ZeroClipboard
The ZeroClipboard library provides an easy way to copy text to the clipboard using an invisible Adobe Flash movie and a JavaScript interface.
I have a weekend project I’ll be using this for to solve an issue at work once and for all.
nsnotifyd
The nsnotifyd daemon monitors a set of DNS zones and runs a command when any of them change. It listens for DNS NOTIFY messages so it can respond to changes promptly. It also uses each zone’s SOA refresh and retry parameters to poll for updates if nsnotifyd does not receive NOTIFY messages more frequently.
Anywhere you currently have a cron job which is monitoring updates to DNS zones, you might want to run it under nsnotifyd instead of cron, so your script runs as soon as the zone changes instead of running at fixed intervals.
