When enabling Visual effects Zend wouldn’t maximize anymore. So after a bit of googling I found a nice tutorial to fix the problem with Zend.

The certificates of the courier imapd-ssl and pop3d-ssl were expired. After some searching I found how to renew them:

sudo aptitude install courier-pop-ssl

nano /etc/courier/imapd.cnf #edit the CN
nano /etc/courier/pop3d.cnf #edit the CN

mv /usr/lib/courier/pop3d.pem /usr/lib/courier/pop3d.pem.old
mv /usr/lib/courier/imapd3d.pem /usr/lib/courier/imapd.pem.old

/usr/lib/courier/mkimapdcert
/usrlib/courier/mkpop3dcert

cp /usr/lib/courier/pop3d.pem /etc/courier/
cp /usr/lib/courier/imapd.pem /etc/courier/

/etc/init.d/courier-authdaemon restart
/etc/init.d/courier-imap restart
/etc/init.d/courier-imap-ssl restart
/etc/init.d/courier-pop restart
/etc/init.d/courier-pop-ssl restart

With thanks to this post.

If first thought that /usr/lib/courier/mkimapdcert generates the certificates in the wrong path. But on another server the cp command complained that the two files were identical. So it looks like they are hard-linked or something…

I read on OSnews about the alpha release of Haiku. It’s been several years since I installed BeOS the last time so I decided to try Haiku.

I first tried it on virtualbox but I didn’t get the networking to work flawlessly so I decided to install it on libvirt. I expected quite a hassle but it was done in a whissle.

First download the raw image of Haiku and run something like:

sudo virt-install --name="Haiku" --ram=512 --hvm --accelerate --import --file=/media/second_disk/vm-images/haiku-r1alpha1.image --vnc --bridge=virbr0

Next I had to edit the Haiku libvirt xml to change the default nic model.  I always stop the libvirt service just to be sure. Then edit this file: /etc/libvirt/qemu/Haiku.xml

Make sure the nic looks something like:

<interface type='bridge'>
<mac address='54:52:00:6a:14:17'/>
<source bridge='virbr0'/>
<model type='e1000'/>
</interface>

I first tried the rtl8139 interface but that isn’t supported by Haiku :s A list of possible interfaces can be found on the libvirt website.

I can now access it via vnc. But Ubuntu has some kind of bug in the vnc client of virt-viewer so it is sllooooooowwwww…

Too lazy to type something usefull here. Just for my own reference…

Tomato is a replacement firmware for Linksys’ WRT54GL and it rocks!

I’ve installed it on my home router and on the new router of my boss. Both had other routers ( a Belkin and a US Robotics) and a lot of troubles with the stupid things. After switching to Tomato we’ve had no troubles at all! Upgrading was a breeze.

At work we still have a D-link but the conncetion keeps dropping. If I set it to WPA1 OR WPA2: no troubles. But WPA1 AND 2 it can’t handle So one of these days I’ve got to pick up a nice blue Linksys and install Tomato on it.

I’ve ditched Ruby for my mpd project and started using Python. Not that I like python that much more but the Gstreamer library for python is much more complete. I really wanted gapless playback and the Ruby Gstreamer libray just doesn’t support that. If it does by the time you read this: please let me know

The new Pmpd project (looking for a better name) can be found on github. The hardest part so far is having to restructure the sources. Python is not a difficult language to master at all but I’m very picky on how everything fits together. My ruby project felt right on that part. But the python equivelant has some things I just don’t like enough up to now.

Since a few version of virtualmin I had some problems with checking the server configuration.

The problem is that I have manually patched suexec and the php fcgid script is in /var/www and not /home.

I had this error for quite a while but last week I fixed it. It was quite simple. Just change this code in “/usr/share/webmin/virtual-server/feature-web.pl:

# Make sure home base is under base directory, or template CGI directory is
if ($tmpl->{'web_suexec'} && $suhome &&
!&same_file($suhome, $home_base) &&
!&is_under_directory($suhome, $home_base) &&
(!$cgibase || !&is_under_directory($suhome, $cgibase))) {
return &text('check_ewebsuexechome',
"<tt>$home_base</tt>", "<tt>$suhome</tt>");
}

<p style="text-align: left;">return undef;
}

To:

# Make sure home base is under base directory, or template CGI directory is
return undef;
if ($tmpl->{'web_suexec'} && $suhome &&
!&same_file($suhome, $home_base) &&
!&is_under_directory($suhome, $home_base) &&
(!$cgibase || !&is_under_directory($suhome, $cgibase))) {
return &text('check_ewebsuexechome',
"<tt>$home_base</tt>", "<tt>$suhome</tt>");
}  return undef;
}

So just add “return undef;” to the top of that piece of code. Then it will step out of the function before the additional check is executed.

When removing Wine, lib32nss-mdns got uninstalled and Zend Studio refused to connect with any FTP server. After reinstalling the package everything worked again!

I had some small troubles with updating this wordpress blog. It kept wanting to upgrade via ftp/sftp. But I found this great post which has a solution.

I’ve tried to use sqlite some time ago in Netbeans but I couldn’t get it working. Bot I stumbled upon a blogpost which works perfectly!
