We upgraded our development server to Fedora 10 over the weekend.  Among other things, it runs RT3 - excellent support, issue management, and bug tracking tool.  Once the upgrade was over, we ended up with a semi-working setup of RT3.  The emails were going through just fine, but the web interface was giving out a blank screen with no content or errors or warnings.

Googled a bit, but that didn’t help a lot.   Went through server logs and found an out of memory shout from Storable.pm:

2325:Callback called exit at
../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/thaw.al)
line 415.

Googled for that, but it turned out that quite a few people have the problem with this module running out of memory.  And not only in RT3.

So I left it where it was and had some good night sleep.  And it helped.  In the morning, englightment came in, and I tried reloading the page with cookies and cache cleaned.  It worked.  And then it didn’t work again.  Cleaning cookies was helping for a couple of page views.  So I dived back into the RT_Config.pm file to see my options.  There it was.

=item C<$WebSessionClass>
C<$WebSessionClass> is the class you wish to use for managing Sessions.
It defaults to use your SQL database, but if you are using MySQL 3.x and
plans to use non-ascii Queue names, uncomment and add this line to
F<RT_SiteConfig.pm> will prevent session corruption.
=cut
# Set($WebSessionClass , 'Apache::Session::File');

Once I enabled Apache::Session::File, the problem went away.  We are now back to work, enjoying the new web 2.0 round corners interface, pastel colors, and more.

Open source software activity usually bumps up quite a lot before and during Christmas.  This time around I am waiting for:

• Fedora 10, which should be released today.
• WordPress 2.7, which should be released “some time in November“.
• Firefox 3.1, which is approaching its second beta.

What are your waiting for this year?

There is a lot of noise going about these news:

The Foreign Ministry is migrating all of its 11.000 desktops to GNU/Linux and other Open source applications.

That’s good.  Both the noise and the news.  But it’s not the first time that we hear about this or that government office moving to Linux desktops.  It happened before.  What I am more interested in hearing is the “after” life.  Something along the lines of “Look, we moved to Linux desktops one year ago and we are doing better than ever.  We are happier and we also spend less money”.  How many of those moved roll back to what they had before?  Why did they roll back? How many stay?  How many of those who stay are more satisfied?  How much cheaper it is for them?

That’s what I’d like to hear.

I have recently upgraded my laptop to Fedora 9.  Those of you who come often to this blog or follow me on Twitter, know that I’ve been waiting for this release like for nothing else.  Two technologies in particular - KDE 4 and Firefox 3 - were the center of my focus.  Of course, I could updated them separately and tried them earlier, but I wanted to follow the path of the distribution.

The upgrade itself went fast and easy.  But starting with the first reboot, I was getting more and more negative towards the new release.  While booting for the first time, I got two messages, notifying me that wpa_suppclient service and CUPS daemon failed to start.  While I don’t care much about printers, wireless connectivity is vital for me, so that was a bit discouraging.

The login screen.  It was changed quite a bit, and I didn’t like it much.  Logging in.  Somehow I ended up in Gnome, even though my desktop environment was KDE for the last 7 years or so.  Logout.  Switch into long awaited KDE 4.  From the first look it was beautiful, even though not quite for my tastes.  Surely, I’d need to reconfigure and change a few things. Not a problem for me at all - even more fun so.

Quoting comment in Slashdot discussion:

The truth is both a blessing and a curse. It takes a lot of work to realize the truth and most people will not challenge themselves. Once you learn the truth, however, you are cursed with trying to explain it to others.

This clearly explains the high density of Open Source advocates, as well as many experiences of my own.

By the way -  happy birthday, Open Source!
