Rudkin On Linux, Mac and Tech

For the last couple of weeks I have been running the 64bit beta version of Ubuntu Jaunty Jackalope which will be released on 23rd April.

The computer I am using is a Dell 1525n which has an Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller. After my initial install of Jaunty Jackalope beta all was well, the graphics card was detected and Compiz enabled. This however was short lived as some days later I applied some updates and Compiz could no longer be enabled.

On investigation I discovered that Compiz had ‘blacklisted’ my video card. I have yet to find out why because Compiz has worked without complaint on every version of Ubuntu since Gutsy Gibbon.

I was initially gutted and planned to downgrade to Intrepid, but not to be defeated I did some searching and found out that you can force Compiz to skip the black list checks. To do this you need to create the following file:-

~/.config/compiz/compiz-manager

and add the following line:-

SKIP_CHECKS=yes

After this I was then able to enable Compiz and continue working as I have done for the last year or so. So far I have not seen any issues, so it is still a mystery as to why the GM965/GL960 was blacklisted.

I hope this helps somebody!

Recently I saw some posts on twitter from @mled that contained short URLs linked to his own domain mled.me. After a few tweets I was introduced to the Phurl, the PHP URL Shortening Script which is the result of the hard work of Hidayet Dogan.

This script is very easy to get installed and running on a Linux box with a LAMP setup. I then started to use it. However when posting some Launchpad URLs that contained ‘+’ characters, I discovered that Phurl did not store the URL correctly therefore causing the shortened URL not to wok.

I emailed Hidayet with this question, and overnight I got a response that included the fix:-

in create.php

change:

$url = trim(urldecode(@$_REQUEST['url']));


to:

$url = trim(@$_REQUEST['url']);


This will ensure that URLs are correctly stored in the database, including those containing the ‘+’ character.

I am sure this fix will be included in the next release of Phurl, but to make sure your installation is free from this issue then make the changes above.

We promised a new release every month, and this month we start out with a fresh bugfix release from the 0.15.x series. 0.15.2 brings lots of bugfixes that have been discovered during the last four weeks and some translation updates for the best (and probably most stable) podcast experience available at the moment

Thanks to all who were involved in this release:

* Anders Kvist (1)
* Bastian Kleineidam (1)
* Fabio Fiorentini (1)
* Gonçalo Cordeiro (1)
* Jim Nygård (1)
* Marco Antonio Villegas Vega (2)
* Paul Rudkin (1)
* Silvio Sisto (1)
* Steven Oxley (1)
* Thomas Perl (15)
* Torbjörn Wassberg (1)

The release contains a ChangeLog that contains detailed info on the changes since the last release. As always, you can also extract that information from the Git repository.

In the meantime, we have been hard at work implementing new features and cleaning up the code for the 0.16.x release series. You can check out the (unstable) code from our Git repository and report any bugs that you encounter, so that we can present you a fine new release in a few weeks.

Grab the new release from the download section or wait until the new package becomes available in your distro. As always, we provide .deb packages for Debian and Ubuntu users.

I wanted to upgrade OpenOffice on my Ubuntu 8.10 installation. Surfing the web I found numerous PPA that could be used, but the easiest method seemed to be below.

1. Download the debs from the OpenOffice.org site
2. Tar -xvzf them
3. cd to the directory containing the debs
4. sudo dpkg -i o*.deb
5. sudo dpkg -i desktop_integration/o*.deb

A big thanks to this article at The Open Sourcerer blog

Having recently acquired a DroboShare I have been experimenting with the various applications that are currently available and install. What I felt was missing from the collection was Gerd Knorr’s webfsd. This is a simple and very lightweight http server for serving static content. This would provide me with web access to the contents of my Drobo from any web browser, including Safari on my iPhone.

The question I had was how on earth do I go about doing this? Although Drobo provide an SDK with the information on how to do this, what I needed was a step by step guide to give me a push in the right direction. Fortunately I came across this blog post which takes you through the steps of compiling MediaTomb. This was exactly what I needed. I am familiar with compiling applications for my Ubuntu system, what I wasn’t familiar with was cross compiling – I didn’t know where to start!

I was a little nervous about doing all of this on my main system, so I created a virtual machine of Ubuntu Intrepid 8.10 using VirtualBox. I followed the instructions to the letter up until the compilation of the libraries, I then substituted the webfsd compilation, and the result is now available for download at the DroboSpace Developer Community

For the last year I have been using Synergy at work to enable me to use my Ubuntu laptop using the keyboard and mouse connected to my Windows desktop.   All worked well until I tried to type the ‘@’ symbol on my laptop, instead I would get a ‘Ω’.  Considering the ‘@’ symbol is important in our modern life, this was a real pain.

Searching the web I could find other people with the same problem, but sadly no solution.  Until today!

I stumbled across this blog entry on Synergy Problems and Workarounds and I now have the ‘@’ symbol back on my laptop when using Synergy!

The solution is very simple, in a terminal window type the following:-

echo keycode 24 = q Q at at at at | xmodmap -

Brilliant, thanks to Delta Nova!

Well I am not sure if this bug is general accross the Ubuntu 8.04 family, but I have a Xen based VPS running Virtualmin and recently stumbled accross an issue with the quota calculations.   You can follow the thread posted in the Virtualmin bug tracker but the basic problem was that I got the following errors:-

root@ycits01:/# quotacheck -u -g -f -m /
quotacheck: Cannot create new quotafile //aquota.user.new: File exists
quotacheck: Cannot initialise IO on new quotafile: File exists
quotacheck: Cannot create new quotafile //aquota.group.new: File exists
quotacheck: Cannot initialise IO on new quotafile: File exists

The solution was to run the following:-

mv /aquota.user.new /aquota.user.broken
mv /aquota.group.new /aquota.group.broken
quotacheck -u -g -f -m /

So I hope this is of use to somebody, now all I need to do is find out where I should report the bug!

After the release of gPodder 0.15.0 exposed some problems with installations of Python 2.6 (for example, Ubuntu Jaunty, who did the transition recently), and some other bugs that cropped up and were quickly fixed, we present you here a fresh release, containing (as usual) only bugfixes:

• Make default encoding utf8 on Maemo (nikosapi)
• Fix “You must not use 8-bit bytestrings” (bug 375)
• Fix a regression in the MTP synchronization code (Jérôme Chabod)
• Added missing dependency on python-dbus for the Debian package

Thanks to all bug reporters for helping us getting this release fixed quickly. You can grab the updated source tarball and Debian/Ubuntu packages from the downloads page. If you find additional bugs in this release, please don’t hesistate to report them on our bug tracker.

Taken from gPodder.org:-

We are proud to announce yet another fine release of gPodder: 0.15.0! This release comes with two long-awaited features/fixes:

• Download resuming (bug 19)
• Proper file and folder naming (bug 57)

When you first start this version, it tries to rename your current download folders and files so they have nice, readable names. There might be some occassions where the renaming does not work – please report such problems at our bug tracker.

This release is also the first to include a new command-line utility, gpodder-backup, which is able to create a nice tarball of all your configuration settings and your downloaded files. This is also useful for reporting bugs that only happen with specific user configurations. See the gpodder-backup manpage for details.

I just thought I should create an entry to let everybody know that my previos post Compiling Firefly Media Server under Ubuntu 7.10 (Gutsy Gibbon) also applies to Ubuntu 8.04 (Hardy Heron).
