Into the (open) source


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.


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:


Integrated display terminal in Nautilus


Some of you may remember Tilda, the handy application that the touch of a button showed the terminal in a configurable part of the screen. So I see on the official website hosted on sourceforge it seems that the project is stopped by the 2008. I wrote a brief guide on this application because I thought it although small, still useful and worthy of note. In the same spirit today I speak of "nautilus-terminal": another small application that integrates the terminal window in nautilus.

The steps to install it on Ubuntu are a few simple. First, add a PPA repository.


Shell: Download a website with wget


In today's article we see how a site to download full with the command "wget".

Wget is a download manager open source, included in major Linux distributions. It is a tool command line, of which there is a gui for Gnome ("wget") and a gui for Windows ("wgetGUI"). Today we see some simple instruction, but for those who want to delve into the manual is always available from the terminal by typing "man wget".


Resize all images in a directory


This mini-howto is taken from blog in Kayowas.

Imagemagik is an exceptional tool, I would say essential, it allows an almost endless array of processing on the images.

In systems derived from Debian, the installation is quite a:

[user@localhost ~]$ sudo apt-get install imagemagick

To vary the size of all images in a given directory, you must use the tool "mogrify"In the following way:


“Print” time and date automatically in a photo


Today we are insert current date and time in an image using the terminal. By itself, the procedure is not complicated, let's see how.

Meanwhile, we see how to make us say the date and time from PC:

[user@localhost ~]$ echo $(date -R)
Tue, 24 Aug 2010 11:45:04 +0200

And now let's see how place it in the we are interested in using ImageMagick. This program allows us to perform many image manipulation, without having to go through the GUI. There is also a primitive graphical interface, but ImageMagick is mainly used for a number of automation (that soon we will see) command line, the invoked by PHP.
