Video deshake con Linux: stabilize a shaky video with Transcode pt. 2


Whole an article in the 2013 that was the subject of stabilization of shaky videos.

Notwithstanding that the best outcome would be to use one stabilizer physical (a simple grip with a weight at the lower end) or a accelerometer solidarity (there are those who have made a kinect).

Also in this case we will use Transcode, so if we have not installed it will be necessary to do so:


5 GNOME Shell extensions that will make your life easier


After all hiding from the blog, a mouthful broad appeal is just what we want. I did not want to shoot too high, so I opted for "facilitate" rather than "change". Also because there is little change, not?

Today we see how to speed up some operations using extensions Gnome Shell. But first, a clarification for those who do not know what is Gnome or Gnome Shell.

Unlike other operating systems, in GNU/Linux the back-end and the GUI are two separate things. A computer that mounts Linux can and should work even without interface


Bcache: the advantage of having a layer between SSD and HDD in terms of speed


Ok, the truth is that these days are not very inspired with titles, unfortunately you will have to settle. Today we talk about speed and SSD / HDD. We will not make the usual benchmark to demonstrate the superiority in speed of solid state disk (it is a fact that it is faster), Instead we understand that it can be useful and economical to add a layer to take care of to communicate the two disks to speed up the process of burning the old HDD.


“Ubuntu One” and “Ubuntu One Music Store” will be decommissioned in August


Anyone who has used Ubuntu at least once in the last years has made the case for Ubuntu One, the cloud service offered by Canonical natively installed on recent distributions of Ubuntu. Ubuntu One is exactly what you would expect from a cloud storage service and so far has winked to all Ubuntu users sometimes left without support from direct competition.

Exactly as Dropbox, SkyDrive, Google Drive, Mega and company allows a subscription for manage a web space remote. The free Basic plan starts from 5GB, acquiring additional functionality, or enrolling their acquaintances through affiliate links is


Terminal: clear the command history


Cencellare command history from the history of the terminal is a simple operation. Default, the last 500 commands type in termilane are stored in the hidden file ".bash_history". The previously typed commands can be read quickly by using the arrow keys ("freccia its" and "down arrow"). This makes it easy to invoke a command recently typed, but it could be a security issue if that session was used by more people. So how does one delete the command history?


Hardware information on Linux


More than three years ago I wrote an article about lshw and lshw-gui, a program and a GUI that allow us to "see" inside the computer all the individual components (CPU, RAM, video card, sound card, network card, etc..). The GUI now has changed its name, it is not more than lshw-gui but lshw-gtk. Aside from that, I realize that after more than three years, the article is still current and does not need additions.


Start a program with GUI remotely via SSH


I do not often have to start an application on a remote machine that requires the use of the GUI, more widely in applications to launch and "turn" in background, but it can always happen. I'm thinking for example to those who use a computer as a multimedia station (with XBMC setup is very simple) or even just to experience.

Suffice it to say that you can do, but it is necessary to direct the GUI application to a screen in particular.


Enable the plugin “zen coding” su gedit


For those who do not know, gedit is the text editor of choice for any Linux distribution based on Gnome. It is preinstalled on most Linux distributions, with the exception of those based on different window managers from Gnome (Where, xfce, enlightenment, etc..). It is primarily used for editing configuration files for system, but supports a large number of programming languages ​​and is expandable with plugins dedicated.

For this reason, before use Brackets, I used Gedit also for editing HTML and CSS.

This is gedit.


Small dictionary of the command line in Linux


Like many other things, also command line is subject to mutations. Mutations that occur very slowly (fortunatamennte) and in some cases do not occur just. The one listed below is a beginner cheatsheet of linuxian, i main controls with which to familiarize when you start to use the (one of) free operating system. Obviously, the guide is not complete, In fact, this little guide is not intended to replace all "man page" (otherwise a person would need?), but want to summarize in a practical and fast the most common commands.


Modify users and groups in the new versions of Ubuntu


It can happen for any reason a user (System Administrator) should put his hand to groups in the pc. It can happen for any reason, or program that requires them to change (VirtualBox, Wireshark, etc..). With the new release of Ubuntu, it was decided that the software had reached a maturity that can be administered without user intervention groups, it was decided that the average user does not need to know that there are groups, nor to change them. Remain valid all the terminal commands, but a GUI does not exist.
