Many on line email providers don’t allow you to use their accounts with POP email clients such as Thunderbird 3.1. To solve this “matter” we have a couple of possible solutions: FreePOPs and WebMail. Today, we will discuss about Webmail that we tested on Ubuntu 10.04 LTS and Windows XP. WebMail is substantially a Thunderbird’s add-ons but it is not featured by Mozilla. Using this add-on you are able to manage Yahoo, Hotmail, mail.com, GMail, Libero, and AOL email accounts. The installation is similar in Ubuntu and Windows; on both, you have to install the core WebMail add-on and restart Thunderbird then you can add all the other components (Yahoo, Hotmail, etc..) you prefer. Then you have to modify the Thunderbird server settings following the instructions provided by WebMail:
POP
Server Type : POP
Incoming Server: localhost
UserName : username@domain
SMTP
Server Name: localhost
UserName : username@domain
Do not forget to set the Connection Security to None.
Only on Ubuntu, you need also to manually modify the incoming and outgoing ports because when you use Thunderbird through WebMail on Ubuntu, you will have a “could not connect to server local host; the connection was refused” message. This problem can be easily solved substituting the default ports on both WebMail add-on and Thunderbird ports:
– Thunderbird —> Edit —> Account Settings. Highlight the account you want to manage and go to Server Settings. There you can modify the POP Server Mail port setting it to a number bigger than 1000 (in my case I put 1250). Then go to Outgoing Servers and Edit the SMTP account you want to modify (I changed the default port to 1025).
– Thunderbird —> Tools —> Add-ons —> WebMail —> Preferences and put the same port numbers you have set on the previous step.
All this because ports below 1024 seems to be blocked on Ubuntu (if you know why, please post a comment).
For security, restart Thunderbird and it will immediately download and send your emails. Last but not least, if your on line email account is not supported by WebMail, do not forget to try FreePOPs. 
Since the first release many thins has been changed on BleachBit. I perfectly remind its first version that I uninstalled because I didn’t feel comfortable with the possible disaster I could do on my Ubuntu computer. Now BleachBit is very different: more powerful and easy to use! This software can be used on Linux (in my test I used Ubuntu 10.04 LTS) and Windows. To install it on Ubuntu you have to use Synaptics ( System —> Administration —> Synaptics) and search for bleachbit in the search bar. For the Windows installation please, download the .exe file and install it. After the installation on Ubuntu, open BleachBit going to Applications —> System Tools —> BleachBit. Now, you have a very understandable menu bar in the left side of your screen. If you click on the main sub-menus you can automatically read some information about what every option will delete on tour PC. Moreover, if the delete options you choose are potentially dangerous, a pop up mini alert will inform you about the risks. We recommend to use the Preview option before bleaching your PS. In this way you can have a final picture of what you are doing and how many bytes are you deleting. On the preference menu you can decide to overwrite files to hide contents or to run BleachBit every time you start your computer. Last but not least, BleachBit supports many languages that you can select from Edit —> Preferences —> Languages.
Usually, when you shut down your Linux OS, you have the option to Hibernate your computer. Using this option you are 100% sure that, when you power-on again your PC, you will find exactly the same programs, browser tabs and system configuration you. In Windows XP you have the same option but often it is hidden. If you have access to your XP computer as Administrator, you can follow the following instruction to restore it: Start —> Control Panel —> Power Options. Find the Hibernate tab and then click on Enable Hibernation. That’s it!
On Thunderbird, the only way to be 99% sure nobody will read your emails is to save your profile on an encrypted folder (or disk partition) using e.g. TrueCrypt but if you are not concerned that you are under surveillance, you can simply use a quick and useful trick that allows Thunderbird to ask for the Master password every time you launch it.
In Ubuntu you have to follow two different steps. First of all, go to Edit —> Preferences —> Security —> Passwords and create your Master Password. Secondly, go to Edit —> Preferences —> Advanced —> Config Editor (click on “I’ll be careful, I promise”). Then in the filter bar, type password and change the parameter for mail.password_protect_local_cache to True. The next time you will launch Thunderbird nothing will be displayed (old and new emails) before you insert the correct Master Password.
If you are using Thunderbird on Windows you have to modify mail.password_protect_local_cache going to Tools —> Options —> Advanced —> Config Editor (click on “I’ll be careful, I promise”). Then, as for Ubuntu, in the filter bar type password and change the parameter for mail.password_protect_local_cache to True.
Installing software on Ubuntu is really easy but sometimes we can have problems to uninstall it if we have not used the Package Manager (Synaptic till Ubuntu 9.04 and later through the Software Center) or a .deb package. To fastly uninstall all the software you do not need or you are not fond of, you can type in the Terminal:
sudo dpkg -r your_file
An alternative and powerful way is typing:
sudo apt-get remove your_file
(where your_file it is the name of the software you want to remove)
or, if you want to completely cancel also the configuration files:
sudo apt-get --purge remove your_file
If you want to check what software is installed on you Ubuntu you can use:
dpkg --list
and you will obtain a complete list of software and a very short summary for each package.
What about losing your laptop? Obviously the chances to find it and have it back are very few! But there are several software you can install on your laptop to trace the ip and geo-location of te laptop and with a bit of fortune you could find it. Prey is one of these programs you can use and it is particularly interesting because it is open source and free up to three laptops. After the download of the proper version for your OS (Linux, Windows, Mac OS X or Android) you have to run it on your machine and configure it through a very simple interface (on Ubuntu: Applications —> System Tools —> Prey Configurator). Do not forget to select Enable guest account and Wifi autoconnect to improve the possibilities to trace your laptop. You are also asked to provide an email account where you will receive the geo-location reports if your laptop is stolen. When you activate your Prey account do not forget to fill in the Configuration and Modules tabs. Personally we suggest to switch to ON the following commands: Auto update, Notify new reports and all the commands contained in the left column of the Modules tab. At this point, if your laptop is missed, you have to log in your on-line Prey account and, in the Configuration tab, switch the Missing option on YES. Since this moment, Prey software on your laptop is activated and will start sending reports to your email and to your Prey webpage. Last but not least, to better protect your laptop I suggest to hide or cancel the Prey Configurator icon from the OS menu (in Ubuntu: System —> Preferences —> Main Menu —> System Tools and deselect Prey Configurator).
Hace unos días he encontrado esta nueva aplicación para Linux, se llama CLI Companion. Aunque Linux ha evolucionado muchísimo y hay que reconocer que ya casi no hace falta hacer uso de la Consola para ejecutar programas y tareas varias, pero también hay veces que gracias al uso de la Consola se puede solucionar pequeños problema que de otra forma seria bastante mas complicado. En esos casos CliCompanion nos hecha una mano añadiendo una lista con diferentes comandos junto a nuestro terminal. La lista de los comando no es infinita, viene con unos cuantos; para cada comando hay una referencia donde se explica la función, también es posible añadir comandos y los parámetros correspondientes. Además CliCompanion tiene un apartado de búsqueda donde es posible encontrar el comando que mas nos interese en cada momento. Desde cuando lo instalé en mi Kubuntu 10.04, tengo que confirmar que es una muy buena aplicación y puede ser instalada con lo repositorios correspondientes y tener futuras actualizaciones o directamente através el paquete .DEB. Os dejo el enlace de la Web: http://okiebuntu.homelinux.com/okwiki/clicompanion
Since few hours, the new Ubuntu 10.10 is available for the download and installation. This version has some new tasks as a better look and a powerful Software Center that seems to be easier than ever also thanks to the feature “where is it?”. Moreover, F-Spot has been substituted by the more powerful and complete Shotwell as main photo manager. The new sound menu included in Ubuntu 10.10 Maverick Meerkat displays more useful information and song you are playing in Rhythmbox. Last but not least, some new delightful Themes and Backgrounds have been added.
On the weaknesses side, we focus our attention on the first paid application (It is really necessary? Do we need it?) and the hardware requirements. In fact reading the Ubuntu wiki the only requirement is a RAM of more than 256MB but Pleia2 and WebUpd8 believe that the 10.10 version does not run properly on processor below i686 and this is a real uncomfortable limitation! Ubuntu has always run on all types of hardware (this is one of its main key features) and this news, if confirmed by tests, could influence users choice to other distributions as Knoppix or Fedora. We really hope that Ubuntu 10.10 will have just the declared 256MB of RAM limitation but today we have to ask ourselves if a new Knoppix era is coming.
