TODO or not TODO, that’s the question?

Added a new page which contains a todo list of stuff I want to learn/do.

Why? Let me quote myself 🙂

“My head gets clodded with lots of ideas and things I need to do. So much that I decided I need to create a list.”

So, if you’d like to know what’s on the list, go see it yourself.

htbaapub.mod updated to 1.03

htbaapub.mod got updated to version 1.03 today.

This version contains an updated fsm.mod, rest.mod and rackspacecloudfiles.mod. If you use any of these modules I recommend updating.

Download htbaapub.mod 1.03 (contains source code of all modules)

fsm.mod updated to 1.01

Today I updated fsm.mod to version 1.01.

This update contains a small example demonstrating creating a FSM machine with 2 states and how to transition between them. The documentation has also been updated.

Download fsm.mod 1.01

Upgrading Ubuntu server delayed for next LTS version

Today at work we decided to wait for the next LTS version of Ubuntu, 10.04. Currently we run 7.04 which is no longer receiving updates. For a while now actually. This summer I worked on planning the upgrade process from 7.04 to 7.10, and finally to 8.04. Which is the current LTS version.

I was able to do a dry run upgrade on our backup server. So I was able to document every step of the upgrade process. Ubuntu upgrades nicely and from 7.04 to 8.04 there are only minor changes that need to be done in our configurations. Even the HP iLO software, for which support on Debian based systems is a bit vague, works out of the box with a native driver. No longer do I need to manually compile the HP iLO driver after every kernel update.

Originally we planned on doing the upgrade somewhere this month or December. But due to tight schedules (it’s quite busy for us) January or February seemed be more likely. Since 10.04, the next LTS version with support until April 2015, is out in April 2010 it likely doesn’t hurt to wait a little bit longer. As far as I know every LTS version so far was easily upgradeable to the next LTS version. So I expect upgrading is going to be a breeze. But of course, I’ll be running tests first when 10.04 gets released.

Why not upgrade to 8.04 first and run that first for a couple of months? Well, support for 8.04 ends in 2013, so 10.04 gives us more years of updates. Also, the upgrade process takes (down)time, time to get there, man-hours that need to be paid etc. etc. Further more, without a doubt, with every upgrade there are some issues going to arise. Small and trivial or stuff that brings down every website that’s running on it. Resolving these issues also takes time, which delays the progress of other projects and what not. By skipping yet another version I think we’ll actually save time.

I’m looking forward to it actually. On of the cool things I’m looking forward to is being able to upgrade Zend Framework from 1.8 to 1.9+. I’m also planning to use memcached and perhaps some PHP optimizer to greatly speed up some of the webapplications. And of course, Perl 5.10 (perhaps 5.12 by then?). Although we, unfortunately, don’t use Perl for our websites I like to keep Perl up to date as we use it for several system administration programs. CouchDB also caught my eye :-).

OK, enough for now. Bedtime :-).
