UPDATE: [01-May-2012] It appears that this PPA repo is currently broken (does not allow to get GPG key and has unmet dependencies on x84_64). It appears that the install on i386 systems does work anyway if you ignore the GPG key error, but I wouldn’t install in that case as PPA installs are security risk enough without GPG errors.

UPDATE: [11-May-2012] The reason the PPA does not work is that it has been disabled by Ubuntu due to a licensing issue with (not hard to guess) Oracle. Flexion.org have however created a script (hosted on Github) to allow the automated update of Java 6 for those who still require it as a dependency.

Whilst I am by no means a photographer I do end up taking quite a few photos (these days pretty much exclusively on my phone) and the management of these photos can be a pain. So far I have never found an program worth the pain over plain old file management.

But having stumbled across Darktable (http://darktable.org/) I think I might have found a worthwile package.

When you need to convert multiple documents to PDF for distribution (or from one Office format to another) there are a few utilities around. The most workable I found is the UNOCONV utility which is build on top of LibreOffice / OpenOffice. This uses the OpenOffice conversion facilities rather than a simple PDF print driver.

On Ubuntu it can be installed via Software Center or via apt-get from the core repositories.

Getting Multifunction Printers to scan under Linux can be a bit of a pain. The Samsung SCX-3400 I had to install recently was no exception.

Here are the necessary steps I had to perform:

1. Ignore all Samsung Provided CD’s and downloads. They do not work under Oneiric Ocelot (11.10)
2. Add Samsung Unified Driver repository http://www.bchemnet.com/suldr/smfpv3.html
3. Install Samsung drivers and libsane-extras
4. Edit sane configuration files

vim /etc/apt/sources.list
#add the Samsung Unified Driver Repo
deb http://www.bchemnet.com/suldr/ debian extra

wget http://www.bchemnet.com/suldr/suldr.gpg
apt-key add suldr.gpg
apt-get update
apt-get install samsungmfp-data samsungmfp-driver samsungmfp-network samsungmfp-scanner samsungmfp-configurator-data samsungmfp-configurator-qt4 libsane-extras

The following sane config files need to be modified (add lines)

Connecting to IPSec VPN gateways has always been one of the more painful things to do. Unfortunately Cisco is not helping by being extremely sluggish on making their utilities available on most recent OS revisions (you can’t even get their QuickVPN client to work properly on 64bit Win7 yet). Operating System support outside of Windows seems to be pretty much non-existent (see https://supportforums.cisco.com/thread/2040595).

Shame on you Cisco !

Option 1 – running QuickVPN under using wine

Download the QuickVPN client

One of the features I missed since the good old Android 1.5 days was the ability to take screen-shots on the device. Prior to Android 4 (ICS) the only workable way to create screen-shots was to connect via USB cable and use the Android SDK to make remote screen-shots.

On Android 4.0 all you have to do is press Volume Down Key + Power Key down at the same time and hold. You should hear the camera click (if audio is on) and Android will show a notification that the screenshot was saved on your device and you can now upload or transfer to your favourite service.

With the release of the final VLC 2.0 player you need to add a back-port (the next version 12.04 will have it included in the main repositories) PPA to Oneiric Ocelot (11.10)

One of the most important utilities on any computer is a decent text editing tool. Since there are as literally hundreds of text-editors out there you would think it is an easy task to find a similar one for each platform.

Since I have now switched to Ubuntu completely it was necessary to find a permanent alternative on that platform since Notepad++ is only available on Windows.

To get an idea on the current power usage and some suggestions on how to improve power-management ‘powertop‘ is a must-have.

sudo apt-get install powertop

EDIT: Here are some tweaks if you install 12.04 (Precise Pangolin).

Since I will have to do a fair amount of traveling in the next year I was in need of upgrading my trusted workhorse of Toshiba Qosmio F60 to a more portable option that will be easier on the shoulders during long travels. After doing some research into which of the major manufacturers offer the best support for a Linux based Operating System it came down to a final two: the Intel i7 variants of Samsung Series 9 and the Toshiba Z830.

If you need to check websites for mobile compliance on a regular basis you know that having a device to constantly check is painful and slows down your work during debugging and phases of constant change.

There are a few tools that will make this work a lot easier:

Thanks to Olivier Berten for providing this package via his PPA Repo !

sudo add-apt-repository ppa:olivier-berten/misc
sudo apt-get update
sudo apt-get install mysql-workbench-gpl

EDIT: this has been confirmed to work on Ubuntu 12.04 (Precise Pangolin) as well).
