Employee +3 Vote Up -0Vote Down

Last weekend I got to present to the MySQL Developers Room at FOSDEM in Brussels.

The subject of my presentation was NoSQL and SQL the best of both worlds

The downside comes in the form of losing ACID transactions, consistency, flexible queries and data integrity checks. What if you could have the best of both worlds? This session shows how MySQL Cluster provides …

Which App is Using a Port?
+0 Vote Up -0Vote Down

Have you ever tried to start a server like MySQL and been amazed to see an error that the port is already in use? You rack your brain and try to figure out what it would be to no avail. Sometimes you do a “ps” in Linux and don’t even see anything that you think would be using the port. Well, forutantely, there are some tricks to help you find out without doing a reboot. If it is a production server, a reboot may not be an option anyway!

Below are some methods to help. We will start by looking at the “fuser” utility provided with many Linux distros:

fuser -n tcp 80
80/tcp:               1029  1030  1824  1838  1839  1840  1841 13972 14136 14137 14712 …

While this script may not work as-is for everyone, it should at least provide a basis for such a script. This script has been modified to send an email instead of plug directly into the MySQL Enterprise Monitor. But, it hopefully will get our creative juices flowing…

#!/bin/bash

# This script does a very simple test for checking disk space.

Our PHP Experiences

Many of the DBA’s at Itchy Ninja Software, began their careers as PHP Programmers, or before… We remember times sitting in a small office together writing PHP code before there were even books on the subject! We were scouring the web looking for examples and such and relying heavy on the documentation at the php.net site!

We wrote custom shopping carts before the days of oscommerce, zencart, and such. We wrote code to interface with payment gateways and process credit cards live. We also wrote code to pull products from MySQL databases, show staff members, and such. We worked for a newspaper group and were writing news “engines” to pull the articles, archive data, …
