Configure Apache after installation

Una regola d'oro: You should never have to manage a website from your home directory. MAY. Non dovresti dare al server web la possibilità di passare attraverso la /home/ to see the directory structure, as well as all other subfolders. A poorly configured Web server, or not configured, or without patch can cause a huge loss of data, or loss of credentials, likely to put personal data and access of different users at risk. (more…)

Delete the silence at the beginning and end of an audio file with SoX

SoX It is a tool for Editing audio files via the command line in Linux. Some past projects will allow the use through GUI, but they were in time abandoned all and there remained only the command line (not that I mind). Often the audio file is set to a silent too long beginning or end of the file. HE, as in my case, the files are queued in audio player, or on a CD the wait is nervous. SoX well as do virtually anything with audio files, It allows you to remove the silence in the input and output, returning a file ready to be queued or burn (and often much lighter original).

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: (more…)

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? (more…)

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. (more…)

LibreOffice from terminal: convert to PDF

With today's article we complete the article in the 31 May concerning the Printing from Client to Server, no drivers whatsoever. Perhaps not everyone knows that LibreOffice and OpenOffice integrate between their packages some commands from flipping through the terminal. These commands are identical for all operating systems (you, for Windows) and produce the same results. Among these we see today is the syntax for convert any file type through terminal opened with LibreOffice / OpenOffice in PDF. The command for Linux is as follows: (more…)

Cut a section of video with ffmpeg

Today's article purpose is to be a reference for those who want cut a video from one point to another with ffmpeg ( then using the terminal). Strange, true? To change what products we use highly graphical far more graphics you can imagine. Often the video is too long to be cut, and a full program (with gui and all) consumes too many resources and slows down the system. The syntax is very simple, in a single line of terminal (more…)
