Clear Address Line in Firefox with Xclear

This add-on places an X-icon at the end of the url. There are several other add-ons that do this, but this one is really lightweight and doesn't need any toolbar buttons. The functionality is more similar like the ones found in Konqueror.

Get a List of Installed Software in Chronological Order

There is a single log file that records all the apt activities, such as installs or upgrades, for the various package managers (dpkg, apt-get, synaptic, aptitude). It can be found here : /var/log/dpkg.log.
If you want to have a more comprehensive history of the installed packages, you can use:
cat /var/log/dpkg.log* | grep "\ install\ " | sort
The result is a chronological list of package installation events. (Note that if a package was installed and subsequently removed, it will still be on the list.)

It turns out that there used to be an apt-history package, but the creator gave it up -due to the fact that dpkg now does logging- in favor of a small script solution: http://redclay.altervista.org/wiki/doku.php?id=projects:old-projects .
Below is the bash function from that web site.

function apt-history(){
case "$1" in
install)
cat /var/log/dpkg.log | grep 'install '
;;
upgrade|remove)
cat /var/log/dpkg.log | grep $1
;;
rollback)
cat /var/log/dpkg.log | grep upgrade | \
grep "$2" -A10000000 | \
grep "$3" -B10000000 | \
awk '{print $4"="$5}'
;;
*)
cat /var/log/dpkg.log
;;
esac
}


The code should be added to /root/.bashrc.
To run apt-history, you need to become root. Entering apt-history with no parameter will simply dump the change log file. To select what activities you want to see, you can enter one of install, upgrade, remove, rollback as a single parameter to apt-history.

Another way to quickly extract informations from apt logs (term.log) is apt-log .
Some examples that would help understanding the common usage of apt-log : http://mavior.eu/apt-log/examples/

Edit : another way to list your installed packages is http://man.cx/apt-show-versions

Recreate Debian Packages with dpkg-repack

Dpkg-repack creates a .deb file out of a Debian package that has already been installed on your system. If any changes have been made to the package while it was unpacked (ie, files in /etc modified), the new package will inherit the changes.
This utility can make it easy to copy packages from one computer to another, or to recreate packages that are installed on your system, but are no longer available elsewhere.
Dpkg-repack should be run as root.
If you don't wish to run the rebuild as root, and you have the fakeroot package installed you can do so as follows: $ fakeroot -u dpkg-repack packagename.
Dpkg-repack will place the created package in the current directory.

Run Spotify with Wine

Spotify is a digital music service that gives you access to millions of songs. They achieve this by licensing the tracks from record companies in a similar way to radio stations, and they pay for it with advertising. You hear the occasional advert between tracks, and there are also options to pay a monthly subscription for a premium account. They do have a preview version client for Linux which I installed, but everytime I try to log in I get the message Use of this device is not enabled for your account. From their site : As a preview release this version is still unsupported, but we’re running it ourselves and will try to make sure it keeps pace with its Mac and Windows siblings. As we haven’t found a reliable way to display ads yet, this version is only available to Spotify Premium subscribers.
Luckily it runs well under wine . With the open version you will get 20 hours per month of streaming ( free ).
There is a problem playing local files with wine though. A solution is not far away, what I used was :
wget http://webupd8.googlecode.com/files/winemp3.acm -O ~/.wine/drive_c/windows/system32/winemp3.acm
After that run winecfg and under the Libraries tab enter winemp3.acm under New override for library and click Add. Have fun with Spotify !

There's even Despotify , an open source client and library for Spotify’s streamed music platform. Spotify decided to block access for non-premium subscribers. !

 If you want to disable the spotify tray icon you should start reading here .

How to Style GTK Applications When Running KDE

You will need two packages : gtk-qt-engine and system-config-gtk-kde
The GTK-Qt Theme Engine (also known as gtk-qt-engine) is a GTK+ 2 theme engine that calls Qt 4 to do the actual drawing. This makes your GTK+ 2 applications look almost like real Qt 4 applications and gives you a more unified desktop experience.

This style can be configured within KDE4's systemsettings using package
system-config-gtk-kde .

Check Your Local Time

http://www.timeticker.com/
The exact time of the world. A full featured Multimedia-Site created with Flash by Martin Zwernemann. Have fun!
http://time.is/
Time.is is synchronized with an atomic clock - the most accurate time source in the world. The displayed time will normally have a precision of 0.02-0.10 seconds. The precision depends on your internet connection and how busy your computer is.

Using a Hosts File To Make The Internet Not Suck (as much)

The hosts file is a computer file used in an operating system to map hostnames to IP addresses. The hosts file is a plain-text file and is traditionally named hosts. It's like an address book. When you type an address like www.google.com into your browser, the hosts file is consulted to see if you have the IP address, or "telephone number," for that site. If you do, then your computer will "call it" and the site will open. If not, your computer will ask your ISP's (internet service provider) computer for the phone number before it can "call" that site. Most of the time, you do not have addresses in your "address book," because you have not put any there. Therefore, most of the time your computer asks for the IP address from your ISP to find sites.  If you put ad server names into your hosts file with your own computer's IP address, your computer will never be able to contact the ad server. It will try to, but it will be simply calling itself and get a "busy signal" of sorts. Your computer will then give up calling the ad server and no ads will be loaded, nor will any tracking take place. Your choices for blocking sites are not just limited to blocking ad servers. In many cases using a well designed hosts file can speed the loading of web pages by not having to wait for these ads, annoying banners, hit counters, etc. to load.
Computers have a host address of their own - it is known as the "localhost" address, with an IP address of 127.0.0.1 which it uses to refer to itself. If you associate another computer's host name with your localhost IP address, you have effectively blocked that host since all attempts to access it will lead back to you.

Severals sites provide hosts files  
http://hostsfile.mine.nu/
http://www.mvps.org/winhelp2002/hosts.htm
http://someonewhocares.org/hosts/

The hosts file is located  in the /etc directory as /etc/hosts.
If there are currently entries in your existing hosts file, then open the ad-blocking hosts file. Copy the text from it to add to the bottom of any existing text in your current hosts file.

Debget to Download a Deb

Debget will download a .deb file for one or more packages from a Debian mirror.
It uses apt-get to find out the URL so it will download the same version from the same server as apt-get would do.The .deb will be downloaded with curl and stored in your working directory. Debget belongs to the package debian-goodies. Not to be confused with getdeb !

Debian Snapshot Archive

The snapshot archive is a wayback machine that allows access to old packages based on dates and version numbers. It consists of all past and current packages the Debian archive provides. 

Manpages Online

From this page : So I thought, why isn't there a page with all manpages? So I just built one.

Faenza Icon Theme

Gnome users go to tiheum.deviantart.com/art/Faenza-Icons....
Download Faenza_Icons_by_tiheum.zip.  To have it extracted in one place : mkdir Faenza-icons. Put the zip file in it and unzip. Extract Faenza.tar.gz and Faenza-Dark.tar.gz. Put directory Faenza and/or Faenza-Dark in ~/.icons or /usr/share/icons.

Autogenerate and Use a Swap File

Package: dphys-swapfile from http://packages.debian.org/squeeze/dphys-swapfile . This init.d script exists so one does not need to have a fixed size swap partition. Instead install without swap partition and then run this, with file size (re-)computed automatically to fit the current RAM size. 
After the package has been installed whenever you boot you'll have /var/swap created. You can verify this yourself with the swapon command :
 /sbin/swapon  -s
Filename                Type        Size          Used    Priority
/var/swap                  file        2097144    0           -1

Apt-get upgrade "the following packages have been kept back"

Sometimes you get this message when running apt-get upgrade. The solution is simple : just run apt-get install followed by the list of packages returned after the following packages have been kept back message. This works well enough to get rid of any errors.
