Last active August 9, 2016 18:21
Google spreadsheet function for signing S3 URLs (very handy for CSV cost allocation reports when combined with the ImportData() function)
function sign_s3(access_key, private_key, bucket, object_name, validity, base_url) {
if(!base_url) {
base_url = "http://s3.amazonaws.com";
}
if(!validity) {
validity = 60;
}
expires = Math.floor((new Date()).getTime() / 1000) + validity;
object_name = encodeURIComponent(object_name);
stringToSign = "GET\n\n\n"+expires+"\n/"+bucket+"/"+object_name;

andsens / convert_db_encoding.php
Created October 3, 2012 10:32
Converts an entire database to utf-8. Handy when you forgot to set default_encoding etc. in my.cnf
#/usr/bin/php
<?php
$mysqli = new mysqli('hostname', 'username', 'password');
$result = $mysqli->query(
"SELECT `TABLE_SCHEMA`, `TABLE_NAME` FROM `information_schema`.`TABLES`
WHERE
`TABLE_COLLATION` != 'utf8_general_ci'
AND `TABLE_SCHEMA` != 'mysql'
AND `TABLE_SCHEMA` != 'information_schema'");

Backup all MySQL databases into separate files
#!/bin/sh
## backup each mysql db into a different file, rather than one big file
## as with --all-databases. This will make restores easier.
## To backup a single database simply add the db name as a parameter (or multiple dbs)
## Putting the script in /var/backups/mysql seems sensible... on a debian machine that is
## Create the user and directories
# mkdir -p /var/backups/mysql/databases
# useradd --home-dir /var/backups/mysql --gid backup --no-create-home mysql-backup
## Remember to make the script executable, and unreadable by others
