Dirty Hack #37: Reflection is hard. Have a decoder you've written in Go and don't want to write all the logic for reflection to store data in native types? Does your decoder output map[string]interface{} and []interface{} flavored data? Problem solved: just marshal and unmarshal using the JSON package.
package main
import (
"bufio"
"log"
"strconv"
)

For all *.txt and *.awd files in the data folder, calculate the sum of each line across all files starting at the 20th value.
import glob
output = []
# For both extensions
for ext in ["txt", "awd"]:
# For all files matching the current extension
for filename in glob.iglob("data/*.{}".format(ext)):
print filename

Relatively painless magnet uri generation for torrentz.eu. There's some extra scaffolding for extension related stuff but this is the main guts.
// Relatively painless magnet uri generation for torrentz.eu. Digging reveals
// that the torrent hash and id (torrentz.eu specific) are stored as hidden
// inputs for the comment system. All that's required is some Ajax and string
// parsing for the announce list and some html injection to add the link to

// Get the torrent name, hash and id (for announce list lookup)
var name = $(".download>h2>span").first().text();
var hash = $(':input[name="hash"]').first().val()
var torrent = $(':input[name="torrent"]').first().val()
