Entering the Iron Man Blogging Challenge

I’ve decided I should enter the Iron Man Blogging Challenge. Basically what you have to do is write 4 Perl related posts within 32 days, with a maximum interval of 10 days between every post. What’s in it for me? If I keep up with the frequency I get a cool badge to put on my blog. But mostly it’s a way for me to focus on Perl and expand my Perl knowledge. The ultimate goal for the Iron Man Blogging Challenge is to promote Perl, which is always a good thing.

The plan currently is to blog about all that’s hot in the Perl web development world; Plack/PSGI, Dancer, Mojolicious and what not. Aside from that I really need to learn about all other cool Perl features I’ve had to miss whilst programming PHP for over 3,5 years full time. Programming in PHP for that long is no fun at all and am glad I was able to convince my boss to use Perl for future projects, making me a happy programmer again.

Besides professionally I also do some programming in my free time. Am a fan of BlitzMax, a BASIC flavor with OOP support, for which I’m working on a Catalyst based website (Maximus) which is supposed to be a lightweight CPAN, but for BlitzMax. I’ve written various BlitzMax modules as well. Am also a CPAN author (CKRAS), maintaining a couple of modules. Of which my first, Mollie::Micropayment, showed horrible influence of PHP. It works, but it’s not pretty.

So, that should do it for my first post. Will try to write a blog post for the challenge every week now.

Change is coming

Which apparently is the slogan for launching Ubuntu 10.04. I think this is going to be a very nice LTS release. It’s too bad that they didn’t include Perl 5.12 in it, but that’s understandable as it just got released; although compiling your own is very easy. On the other hand, PHP 5.3 got in there thanks to the pressure of some fellow Dutchmen. Not that I’m a big fan of PHP, but PHP 5.3 has some nice additions such as closures.

Hello World!

Just testing if my syntax highlighter works!

  1. #!/usr/bin/env perl
  2. "Hello World!\n";

This seems to be working and after some changes to my themes’ stylesheet it looks a bit better.

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 :-).
