Needed to get a LAMP environment up and running for some Kohana development. Starting with a more or less fresh install of Ubuntu, here’s what I did.

MySQL tables for continent names, country names and their ISO-3166 codes
Here is a MySQL table containing continent names, country names and their ISO-3166 codes.
Needed one a while ago, but the ones I found were either kind of lacking or kind of old. So I made one myself by converting a datafile on Wikipedia into the format I wanted. Used some regular expressions and manual corrections. Later I also went through newsletters with Updates on ISO 3166. Hopefully I got it all right, and hopefully it can save you and others some time as well.
If you find any mistakes or updates I’ve missed, please let me know 
MySQL: How to clone a table
Ever wanted to, for some reason, clone a database table? Don’t really want to export anything or figure out what statement was used to create that table? Turns out that’s a lot easier to do than I thought it was.
MySQL: Filtering with Regular Expressions
Today I wanted to list all all users in a database who had been too lazy to uppercase the first letter in their name. But how can you do that in MySQL? With regular expressions such a check would be easy to write, but this was in MySQL, not in for example PHP… but wait a minute… MySQL actually supports Regular Expressions? Yes, it does! I honestly had no clue.
How to delete WordPress post revisions
Having revisions on my posts is nice I suppose. But I was starting to get a bit annoyed with the increasingly long list of revisions in each post. And they really did get long. Mainly because I am in a bit of a testing and experimenting phase which means that I have done a lot of adjustments to almost every single post so far because I don’t have 100% control on how I want things or how things will end up looking and so on There’s also of course all the obligatory spelling errors I only discover after I have clicked Publish
Anyways, I found a nice little MySQL snippet to clear out all of them in a French comment to a blog post. Thought I could share it here. That way I won’t lose it either
MySQL: How to reset the root account
I just managed to mess up the MySQL root account. Not a smart idea. After some MySQL manual reading and some serious Google-Fu, I figured out how to fix it.
- Stop the mysql server
- Add the following to the my.cnf file
[mysqld]
skip-grant-tables - Start the mysql server
- Start a mysql client and run the following query
REPLACE INTO mysql.USER VALUES ('localhost','root',PASSWORD('blah'),'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','',0,0,0,0);
- Quit the mysql client
- Stop the mysql server
- Remove what we added to my.cnf in step 2
- Restart the mysql server
Tadaa.
