Simple way to change data in mongo using existing data in a document
// Here my collection is named articles
// I'm changing the blog_name field in every document in that collection to lowercase
db.articles.find().forEach(function(doc){if(typeof(doc.blog_name) == 'string') {doc.blog_name = doc.blog_name.toLowerCase(); db.articles.save(doc); }})

Migrate an svn repository to git and github
# Assume your svn repo is located at svn://example.com/myapp/trunk
# Assume your git repo will be located at [email protected]:example/myapp.git
# First you need to generate a list of all committers in your svn tree.
# Credit David Wheeler
# http://www.justatheory.com/computers/tricks/list-all-svn-committers.html
$ svn log --quiet svn://example.com/myapp/trunk | grep '^r' | awk '{print $3}' | sort -u
# Next, create a file in your home directory named svn-committers following this format

Using mysqldump for backups on a slave. Note the use of --master-data=2, this makes sure we get a global read lock and write out a comment in the sql file with the master log filename and current position. Now this backup is good for adding or bringing back a slave from scratch.
mysqldump -u [user] -p -xQce -R --master-data=2 --max-allowed-packet=1024M -B [db_name] | gzip > [db_name].sql.gz

Backup all databases on a mysql server excluding information/performance_schema and including UDFs/stored procedures. Most useful scheduling this on a slave db.
#!/bin/bash
# No username or passwords in this script, you should use mysql_config_editor
# to store it securely. The login-path in this script is set to "local-backup" so when you create
# your .mylogin.cnf with the mysql-config-editor make sure it is set the same
# See http://dev.mysql.com/doc/refman/5.6/en/mysql-config-editor.html
# An example to create your config for a mysql user "backup":
# shell> sudo mysql_config_editor set --login-path=local-backup --host=localhost --user=backup --password
# The backup user in the mysql server needs these privileges: SELECT, RELOAD, SHOW DATABASES, REPLICATION CLIENT
