Everyday we use USB keys to transfer data without transmitting them through the t. The USB keys and portable disks are small, light and their data capacity allow us to move in privacy huge files. This idyll sometimes is broken by a fatal mistake: we unintentionally delete an important file. Normally, if we are smart we recover the erased file in the Trash but in other situations when we realize the mistake we had made is too late.
In this circumstances is very import to stop to use our USB key or portable disk till we are able to use a good software for data recovering. On Ubuntu you have a wise number of dedicated software that can do this job for you, the most powerful run on Terminal as testdisk, foremost, and scalpel but you can also use a “minimal GUI” software as PhotoRec.
PhotoRec is very intuitive to use and it is able to recover many data formats from jpeg to db. After you install it using Synaptic Package Manager or the Software Center you can launch it in Terminal with:
sudo photorec
Immediately a GUI Terminal interface appears and you have just to follow the instruct ions you visualize on your monitor.
Using the arrows and the Enter keys you have to:
1 – Choose the USB device from where you want to recover the data
2 – Select the partition table (usually Intel)
3 – Specify the partition table
4 – Select the right filesystem where the data were stored
5 – Decide if you want to try the data recovering from all the free space
6 – select the directory where you want to store the recovered data. IMPORTANT: do not store the recovered data on the same USB key you are scanning for recovering
7 – Wait till PhotoRec finishes the recover operations.
PhotoRec is fast and, during our tests, we were able to recover almost the 100% of data. Not bad!!!

This is the situation: you have a IOMEGA Screenplay Pro and while you where trying to find a better output resolution for your monitor you accidentally (or not) selected the HD option and now you are not able to visualize anything.
In few words this is the easiest problem you can afford but also one of the worst because you are not able to visualize the menu and so you cannot revert the right monitor resolution.
I visited many websites but unfortunately I didn’t find any forum or post about this topic. In any case I like to focus your attention on this ScreenPlay Pro HD wiki which is a real mine of information and tips about this specific hardware.
So I tried to “play” with the Screen Play Pro HD remote but I was not able to find a solution without visualizing anything on the monitor.
At the end, when I was thinking to reset the Screenplay and loosing all the data contained, I tried to use an old solution I used different times with other stuff: I pressed the power button for more than 10 seconds while I was switching on the device.
Something happened because the monitor showed me the Screenplay boot up window for a couple of seconds. At this point I pressed the NTSC/PAL button and the Screenplay Pro HD menu was visualized on my monitor again.

If you use Ubuntu 10.04 or any other Linux distribution which doesn’t automatically upgrade your Firefox to the latest version you can force it.
First of all you have to launch Terminal and add the right PPA to the repository:
sudo add-apt-repository ppa:ubuntu-mozilla-security/ppa
Then you need to update and upgrade the OS using:
sudo apt-get update sudo apt-get upgrade
If you are installing Firefox for the first time the right commands are:
sudo add-apt-repository ppa:ubuntu-mozilla-security/ppa sudo apt-get updatesudo apt-get install firefox firefox-gnome-support firefox-locale-en
As usual on Linux, it is not necessary to reboot the computer and you can start immediately to use your updated Firefox.
How ro repair Ubuntu 10.04 LTS if the Update Manager and Synaptics don’t work January 16, 2012

After I installed some new software I wasn’t able to update Ubuntu 10.04 LTS. The Update Manager was not able to check for updates and when I tried to use the Synaptic Package Manager I hadn’t better results. A reboot was not the right solution and I tested different ways to solve my problem saving the Ubuntu installation in my computer.
Searching on internet I discovered that there are few possible solution to avoid this problem and, in case you have the same bug on your computer, I decided to sum-up the most powerful after I successfully tried them.
First of all you can try to force the update process through the Terminal typing:
sudo apt-get update sudo apt-get upgrade
If this doesn’t work you will try with this next step:
sudo rm var/lib/dpkg/lock sudo dpkg --configure -a
Then launch again the Update Manager to verify if you succeed and if nothing happened solve the matter typing:
sudo rm /var/lib/apt/lists/* -vf sudo apt-get update
and try again to launch the Update Manager.
In my case this was enough to restore all the Update Manager features and solve the problem. If you have extra problems about this bug or if you want to suggest alternative solutions, please, don’t hesitate to comment this post.
Time to clean-up! Ubuntu – Linux suggestions. January 4, 2012

Christmas time is ending and today we really don’t know how many relatives used out computer for “just few minutes” or “to quickly (sic) check the emails”. In few words, our Linux PC could have been overstuffed with unwanted temporary files and we haven’t had time to update it. So, it’s time to clean-up!!
First of all I suggest to use BleachBit because, for my experience, it’s the most powerful software to clean temporary files, log files and unwanted traces on your computer. BleachBit is easy to use and, as we described in previous post, very effective.
Then we have to check if our system is really updated so we can use the usual ways as Synaptics Package Manager or quickly run a some simple commands through Terminal to update, upgrade and remove old packages or Kernel.
For this purpose I collected three simple commands and chained them in a single line:
sudo apt-get update && sudo apt-get upgrade && sudo apt-get autoremove
In this way you will be sure that you can start again to work on your Ubuntu as before the Christmas time!
Merry Christmas December 25, 2011

The last generation of external 3.0 usb disks allows us to create fast multi-boot drive that can be used for different purpose. Commonly we use these “special” drives as recovery tools when something goes wrong in our computers or when we would dig, in a deeper way, a particular desktop.
The best software to create multi-boot disks or ISO have been developed for Windows and the only exception is a French, multi-step solution named LiveUSB Multi-Boot.
Today we focus our attention on Sardu a multi-language Italian project developed for Windows machines. After you have downloaded it you can unzip and save the folder in your favorite location. The sardu.exe file will run the program and you can start to decide if you prefer to create a multi-boot ISO or a multi-boot usb key.
The menus are complex but in a couple of minutes you will be able to properly navigate them and select the software and ISO you’d like to have in your CD or USB key. You can also decide to manually add a specific ISO which is not directly supported.
The CD-DVD burner is included in Sardu consequently you can create your bootable CD-DVD in just few clicks.
In the everyday world, Sardu is also useful to test computers when you want to quickly install a Linux distribution and you are not sure about the best one to choice.
Moreover, Sardu is plenty of extra freeware which can help you to recover the GRUB, partitions, lost files and passwords.
Unfortunately Wine is not able to run Sardu in a correct way and when we tested it on Ubuntu we were able to use just few basic features.
Try Lib-Ray: “Sintel” Lib-Ray PROTOTYPE v0.2 December 6, 2011

The following text comes from: http://www.archive.org/details/sintelLib-rayPrototypeV0.2:
‘The Sintel PROTOTYPE of the Lib-Ray free/open fixed media format for high-definition video without DRM or other “anti-features”. Since it is a prototype, it comes with no guarantees about stability or compatibility, but it is best viewed using Google’s Chromium web browser in full-screen mode on a system with a 1920×1080 “full HD” screen. Some features do not yet work even on this configuration, however, as they require elements of HTML5 that are not yet implemented. Because it’s a short movie, the ISO is relatively small (2.1 GB), and it will fit easily onto an inexpensive single-layer DVD-R disk”.
More details about the project are also available from the Lib-Ray site: http://lib-ray.org.
