MariaDB & distributions update, Dec 2013

A few things to note recently, amongst MariaDB in distributions. 

  1. Ubuntu keeps MySQL 5.5 despite MariaDB’s success. There’s a lot of reasons for this, but remember the key takeaway here is MySQL 5.5 & the fact that MariaDB wasn’t even in Debian yet when the decision was made.
  2. MariaDB is now inside of Debian/sid – check out the packages.
  3. RHEL 7 comes with MariaDB 5.5 as a default; this is a good thing.

Now, from a distribution standpoint, we’re looking at starting to ship 10.0 …

Using the PAM authentication plugin

The procedure for using the PAM authentication plugin as documented doesn't work flawlessly on Ubuntu.

So here is how it works on Ubuntu (and probably also on other Debian based systems).

Please note that the PAM authentication plugin is an enterprise feature.

1. Make sure the plugin is loaded

This can be done by adding the following to the mysqld section of my.cnf (Don't forget to restart). You could also use INSTALL PLUGIN to load it without restart.

plugin-load=authentication_pam.so

2.  Add a user which will use the plugin


mysql> CREATE USER 'dveeden'@'localhost' IDENTIFIED WITH authentication_pam;
Query OK, 0 rows affected (0.00 sec)

3. Add a pam config file for 'mysql':
Create /etc/pam.d/mysql with the …

On big technical meetings, or why the end of the UDS is a bad idea

Canonical has just announced that the Ubuntu Developer Summit will no longer be face to face and every six months. Instead it will be entirely online and virtual, using Google Hangouts. (Here is the announcement.)

On the surface, this seems like a good idea: It's cheaper monetarily, it appears to open things up to people who are unable to travel, and it makes it easier to make complete records.

However, I think it's a bad idea, for several interrelated reasons.

Some decision making needs face-time to happen. For whatever reasons, internet-only communication is not enough for a good enough "meeting of the minds" for sticky or subtle engineering and design decisionmaking.

The IETF, who probably have the longest history of any organization ever of online internet-enabled …
