Firefox 6 Is Available in the Official Ubuntu 11 04 Repositories
Firefox 6 (the most secured web browser in the world, kidding, but its pretty darn good though, right? :D) was available for Ubuntu 10.10 and 10.04 users even before it was officially available for the Natty users.
And if you havent disabled your automated updates in Ubuntu Linux, then as soon as they release it you should have it automatically install it. But since I have manually disabled the update manager because it uses too much of your bandwidth which can result in a cluttered YouTube videos :D (kidding, again, but I do have it disabled for other reasons)...
Ive also been a bit busy yesterday and until I manually check this morning I didnt know it was available to Natty users. Anyhow, to install it (in my humble opinion, I think unlike with other releases, FF6 is well worth the update because as promised by Mozilla, it loads itself pretty faster than the previous versions) , perhaps you should re-enable the update manager t OR
just fireup your Terminal window and enter the below command to install the sucker!.
sudo apt-get install firefoxIf youd prefer a more cleaner installation, then first remove your current Firefox browser completely (make sure to take back-ups of your Bookmarks and other naughty stuff), then use the below command first.
sudo apt-get purge firefox
That should do it.

Firma digitale Infocamere e Ubuntu ora funziona!!
Era da qualche tempo che provavo (infruttuosamente) a far funzionare il mio kit di firma digitale Infocamere sotto Ubuntu.
Ora, finalmente, ci sono riuscito, anche se in maniera "provvisoria".
Il mio sistema:
Ubuntu 8.04
Una smart card infocamere, serie 1203
Un lettore di smart card bit4id, Advanced Card Systems, Ltd ACR38 AC1038-based Smart Card Reader
Ho anche un lettore Omnikey Cardman 2020, che non sono riuscito a far funzionare.
Tanta pazienza, molte gugolate, e un pò di fortuna...
Mi sono stati di enorme aiuto:
Guida allinstallazione
Firma digitale e smart card
Installare smart card Università su Ubuntu
Firma digitale con Linux
Installare pcscd
Installare pcsc-tools
sudo apt-get install pcscd pcsc-tools
Per il lettore di carte, avendo io un ACR38, ho installato un altro pacchetto, e precisamente libacr38u
sudo apt-get install libacr38u
A questo punto, occorre provare a vedere se tutto funziona, con pcsc_scan
Questo è il risultato:

CardOS M4.01a (SLE66CX322P)
Per qualche arcano motivo, però, a volte pcsc non parte.
Per verificare se il demone pcscd è caricato:
ps -fe | grep pcsc
Nel mio caso non era caricato, e non partiva neanche con sudo /etc/ini.d/pcscd start.
Ho dovuto digitare:
sudo pcscd -f
E a questo punto mi funzionava tutto :-)
Per far funzionare la smart card su firefox, ho installato opensc e mozilla-opensc
Sudo apt-get install opensc mozilla-opensc libpcsclite1 libopensc2
Dopodichè, bisogna abilitare la smart card su firefox:
1.) Start Mozilla or Firefox or Thunderbird.
----
2.) Select "Tools" on the menu bar, select "Option...".
----
3.) Select "Advanced" Options. Unfold the "Certificates" section. Click on "Manage Security Devices".
----
4.) Click on "Load"
----
5.) Change the name to "OpenSC PKCS#11 Module". Click on "Browse."
----
6.) Select the installation directory. On windows this is usualy "C:Program FilesSmart card bundle". On Linux and Mac OS X choose "/usr/lib/".
Click on "opensc-pkcs11.dll" (windows) or "opensc-pkcs11.so" (Linux, Mac OS X). Click "Open".
----
7.) Click "Ok".
Et voilà! A questo punto sono finalmente riuscito ad accedere al sito della Corte di Cassazione, ed a accessogiustizia.it
Dual boot? No grazie ...
PS: questo howto funziona con la card 1203, mentre non sono riuscito in alcun modo a far riconoscere una card serie 1204...

Flush A Torrent Client for Ubuntu
Although original idea behind the BitTorrent protocol has nothing to do about "illegal" stuff but all about sharing legal (also known as legal torrents), online file sharing between computer users using this revolutionary and awesome protocol.
Anyhow, I dont actually remember the exact data, but it was said that BitTorrent protocol has its fare share of the Internet bandwidth (more than a "fare share" :D) thus some ISP even had to come up with their own tools to block the applications that uses this protocol in order to save this "excessive" usage of their bandwidth.
Then the developers got a bit angry and came up with their own method to make it really hard for the "bad" ISP to block the BitTorrent protocol. Its called the BitTorrent encryption. Now, some people took it the wrong way and thought the developers were helping other to "steal" but as anyone can see, they were just defending A idea, rather than users.

| Flush BitTorrent client in Ubuntu... |
Although, not surprisingly, MS Windows does not come with a BitTorrent clients installed but almost all GNU/Linux distributions (their recent versions) do come with at least one installed by default. Apparently Ubuntu also comes with one called "Transmission" which is pretty darn good too.
But out of your boredom, if youre looking for something else :), then "Flush" is a pretty decent one. But the biggest drawback of Flush is that I couldnt find any option to enable the above mentioned "Protocol encryption". Maybe it enables the encryption by default... but other than that, its a fast loading, easy to use BitTorrent client nonetheless.
Main features...
*. Change Upload/Download speeds.
*. Availability.
*. Show Seeds & Peers.
*. Change communication ports (or set to automatically use a random port at each startup).
*. Manual tracker updates (which is another important thing that helps to speed up things a bit).
*. IP filtering.
*. Max connections per torrent.
*. Create a torrent file from scratch... are just a few to mention.
You can install Flush BitTorrent client in Ubuntu 11.04 Natty Narwhal, 10.10 and 10.04 by using the below command in your Terminal window.
sudo apt-get install flush
That should do it.

Eye Candy Make your Ubuntu 11 04 Desktop look like Mac OS X with Mac4Lin and AWN
I had written post earlier about how you can transform your Ubuntu Desktop into looking like Mac OS X, it become instant hit and to this day I get number of people looking for information about transforming their Ubuntu desktop to look like Mac OS X, and hence I decided to write an updated tutorial. Macbuntu is one alternative, though at the time of writing this post I could not find Macbuntu version for Ubuntu 11.04 and forcefully installing Macbuntu have lead to stability issues and hence I would avoid this approach.
The desktop should somewhat resemble interface of MacOS X, after following the below mentioned steps.
I would be assuming that you are using Ubuntu Classic here and not Unity, I have found Unity to be extremely irritating to work with and I dislike it very much. You can switch to Ubuntu classic by changing to Ubuntu Classic in GDM screen.
Mac4Lin is made by GTK Developer Anirudh Acharya, with the aim of bringing Aqua user interface to POSIX based platform, in simpler words, to operating system the likes of GNU/Linux and hence distributions like Ubuntu.
We would first need to download Mac4Lin theme package and install it onto the system, you can do so easily by issuing the following commands in terminal ( Applications -> Accessories -> Terminal ) window :
wget http://space.dl.sourceforge.net/project/mac4lin/mac4lin/ver.1.0/Mac4Lin_Install_v1.0.zipor alternatively you could look into the source forge page and download the latest archive from multitude of mirrors. Source forge download page of Mac4Lin - http://sourceforge.net/projects/mac4lin/
Once you have downloaded the archive, you need to extract it, you would need to have unzip installed on your system to do so, if you do not have unzip installed you can do so by issuing the following command in terminal window :
sudo apt-get install unzipHowever, if you decide to extract this using terminal you can do so easily by issuing the following command :
mkdir $HOME/mac4linThis should extract the archive into mac4lin directory, you would need to execute shell script to install Mac4Lin theme, chdir into mac4lin directory and then chdir into Mac4Lin_Install_v1.0 directory, once you are in the directory, issue the following command to execute the shell script and begin installation :
unzip Mac4Lin_Install_v1.0.zip -d $HOME/mac4lin
./Mac4Lin_Install_v1.0.shThis should begin the installation procedure, it would ask few questions, you should answer them, and for installing it might need root permission as well and hence would need sudo password,if you follow the instruction carefully Mac4Lin should be installed in Jiffy.
Now you need to install Avant Window Navigator, if you havent installed it already, there are many docks for GNU/Linux, I have found AWN to be extremely stable and good looking and hence I would be using this in this post, additionally, it integrates with Mac4Lin well.
You can install AWN by issuing the following command in Terminal Window :
sudo apt-get install avant-window-navigatorIf the above step completed successfully, you are done transforming your Ubuntu 11.04 based system to a Pseudo MacOS X kind of look. I would recommend after installing AWN and Mac4Lin you restart your system, or at the very least restart X server.
You need to select the newly installed theme, you can do so from System -> Preferences -> Appearance , you should find Mac4Lin Graphite and Mac4Lin Aqua there, based on your personal preference and likes you can chose either one of them, I prefer Mac4Lin Aqua :)
AWN does not load by default and needs to be started from ( Applications -> Accessories -> Avant Window Navigator ), I would advise that you get rid of panel at the bottom (if you are using Ubuntu classic i.e ) by right clicking on the panel and choosing to get rid of panel.
