Question: How to change a column type in MySql?

Answer:

alter table accounts change paswoord paswoord varchar(60);

(see this list of handy mysql commands.)

After upgrading to MySql-server 5, I found my BugZilla installation broken. Luckily I was not the first one with this problem, and Chuck Caplan posted a solution on his blog.

MySql knows a lot of String manipulation functions, of which SUBSTRING_INDEX is very useful to split e.g. adress lines containing comma's :-)

This document covers a very specific, limited purpose, but one that meets a common need: preventing browser, mail, and other clients from complaining about the certificates installed on your server. Not covered is dealing with a commercial root certificate authority (CA). Instead, we will become our own root CA, and sign our own certificates.

Using a small Linux distro like Puppy Linux and a processor emulator like qemu, it is possible to run Linux like any other Windows program.

Puppy is extraordinarily small, yet quite full featured Linux distribution. It boots into a 64MB ramdisk, and the whole caboodle runs in RAM. Unlike live CD distributions that have to keep pulling stuff off the CD, Puppy in its entirety loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly. Puppy Linux has the ability to boot off a flash card or any USB memory device.
