Every now and then my gnome keyboard layout switcher hangs. When my keyboard switcher hangs I can't switch between my two defined languages English and my native Bulgarian
The hang up of the language switcher is makes switching between my two defined languages impossible until I logoff and login again or kill the current GNOME session with CTRL+ALT+BACKSPACE.
Sometimes logging off again is not necessery so I have to logoff and login to GNOME few times until finally the gnome keyboard layout switcher reacts to an issued change language via Alt+Shift or by clicking on it.
Unfortunately the gnome keyboard layout switcher is not available as a process so there is no way to simply kill -HUP the process responsible for it.
Just until today I couldn't find a way how to restart the gnome keyboard layout switcher when it hangs.
Now today I finally found a way to restart it without restarting the whole gnome session or killing completely the Xorg server.
To "fix" up the keyboard switcher when its not responding, I had to issue in gnome-terminal or via ALT+F2:
hipo@noah:~$ gnome-keyboard-properties
As you can see in the screenshot below, one has to press the Move Up button to switch the default order of languages. Once this is done the keyboard layout switcher starts working again. Once working I just used the move up once again to revert back my default language order as it used to be.
I'm not sure what exactly is causing the GNOME 2 keyboard layout switcher to hang (when it does), my guess is it is due to some kind of version incompitability between gnome versions or configurations specific to my computer. In the past I was running Debian Testing/Unstable and then downgraded back to Debian stable, probably this is the reason of the language switcher hangs.

There are two handy Windows commands which can be used to renew IP address or flush prior cached DNS records which often create problems with resolving hosts.
1. To renew the IP address (fetch address from DHCP server)C:\> ipconfig /release
C:\> ipconfig /renew
In above cmd ipconfig /release will de-assign the IP address configured on all Windows LAN and Wireless interfaces, whether ipconfig /renew will send request for IP address to the DNS server.
To unassign and assign again IP address from DHCP server only for a particular LAN or WLAN card:
C:\> ipconfig /release LAN
C:\> ipconfig /renew LAN
C:\> ipconfig /release WLAN
C:\> ipconfig /renew WLAN
2. Adding specific routing to Windows
Windows has a Route command similar by syntax to Linux's route command.
To add routing via a specific predefined IP addresses on Windows the commands should be something like:
C:> Route add 192.168.40.0 mask 255.255.255.0 192.168.41.253
C:> Route add 0.0.0.0 mask 0.0.0.0 192.168.41.254
The first command adds IP 192.168.40.0 in the network of 255 hosts to be routed via 192.168.41.253
The second one adds 192.168.41.254 as a default gateway for all outbound traffic from the Windows host.
To make permanent routing -p switch is used.
3. To clear Windows DNS cache (flush DNS cached records) C:\> ipconfig /flushdns
This will clear all IP records corresponding to hostnames previously cached on the Windows host. Using ipconfig /flushdns is especially handy when IP address for a specific DNS host is changed. Flushing the Windows DNS cache can save us a lot of waiting before the domain example.com starts resolving to the new IP address let's say 1.2.3.4 instead of the old one 2.2.2.2

I've recently received a number of images in JPEG format as a feedback on a project plan that was constructed by a team I'm participating at the university where I study.
Somebody from my project group has scanned or taken snapshots of each of the hard copy paper feedback and has sent it to my mail.
I've received 13 images so I had to open them one by one to get each of the Project Plan to read the feedback on the page this was really unhandy, so I decided to give it a try on how to generate a common PDF file from all my picture files.
Thanksfully it happened to be very easy and trivial using the good old Image Magick
In order to complete the task of generating one PDF from a number of pictures all I did was.1. Switch to the directory where I have saved all my jpeg images
debian:~# cd /home/hipo/Desktop/my_images_directory/
2. Use the convert binary part of imagemagick package to generate the actual PDF file from the group of images
debian:~# convert *.jpg outputpdffile.pdf
If the images are numbered and contain many scanned pages of course you can always pass by all the images to the /usr/bin/convert binary, like for instance:
debian:~# convert 1.jpg 2.jpg 3.jpg 4.jpg 5.jpg outputpdffile.pdf
Even though in my case I had to convert to PDF from multiple JPEG (JPG) pictures, convertion with convert is not restricted to convert only from JPEG, but you can also convert to PDF by using other graphical file formats.
For instance to convert multiple PNG pictures to a single PDF file the command will be absolutely the same except you change the file extension of the graphic files e.g.:
debian:~# convert 1.PNG 2.PNG 3.PNG 4.PNG 5.PNG OUTPUT-PDF-FILE.PDF
I was quite happy eventually to know Linux is so flexible and such a trivial things are able to be completed in such an easy way.
