LibreOffice “Calc”: define the first row of each page

LibreOffice is a suite of open source office for excellence, created by the project OpenOffice when it was bought (along with other products SUN Microsystems) the Oracle. “Calc” is one of the programs included in the suite LibreOffice, it is a spreadsheet. Today's article tries to make life easier for those who have the need to always have certain cells as a page header.

The header row included in Calc, reached by following the menu “Format” – “Page” – “Header row“- “Edit“, is basic and is explained in the screenshot taken from the program, below. (more…)

We recover deleted files with Foremost

Perhaps not everyone knows that when you delete files from our devices, they are not deleted, but only “hidden” waiting to be overwritten, and it is precisely for this reason that we believe that the files deleted can be recovered (always if you are not already been overwritten).

Foremost is a program open source a command line to Linux that recovers deleted files. It is of extreme simplicity, present in the repository and performs its job without fuss. As stated in the site, Foremost was originally developed for l '”Air Force Office of Special Investigation” U.S., and for the “center studies and research information security and systems“. Subsequently was released the source code and even the general public could benefit from the advantages offered by Foremost. (more…)

Changing the pitch of an audio file with Audacity

In today's tutorial we begin to delve into the world of digital audio. Let's start with a simple solution of the problem, problem that many people will ever encounter. How to change the pitch of a file (or of a part of file) lossless audio? The answer is “can not”. To change the pitch you need a small (laughable) loss of information, imperceptible, but it is better to know.

For this tutorial we will use the open source audio editor Audacity, and we will use this audio file.

First of all open Audacity and import the file: “File” – “Import” – “Audio”. (more…)

The simple backup with “Déjà Dup”

Apparently simple interface is not always synonymous with lack of features. The software we are talking about today is Déjà Dup, a simple tool developed for Gnome, initially only for Fedora 13 and already used by the next unborn home Canonical Ubuntu 11.10.

Although the included software will be released to Ubuntu 11.10, This does not mean that we can not already install and run. Among the other is from the present time is in the repositories of Ubuntu to Fedora. (more…)

Shell: Download a website with wget

In today's article we see how you download an entire website 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“. (more…)

Cambiare lingua a Firefox

With the latest update from Mozilla, my fox computer (or should I say “my Panda rosso“) is back to talk in inglese. I do not know why this happened, is probable that the langpack have not been included in the updates released by Canonical, the fact is that for Italian return passages are few, Simple and (I hope) clear.

Lighting effects to images with Gimp and the pack “Lomo Light Leaks”

Today I report an interesting site from which I often take inspiration for the writing of my tutorials. The site is PhotoShopTutorials.ws, and as you can easily guess from the name of the domain is a site full of resources for PhotoShop, usable for most of the cases even with Gimp.

Today we see the “Lomo Light Leaks” pack, a collection of effects to add to their photos to make them look old. In pratica si tratta di 71 different images with the effect “flare” or reflex lenses. To apply the effect to the photo you want, simply open the “Light Leak” superimposed on the image as a new layer and change the mode from the main “Usual” a “Screen”. I also recommend you to resize the “Leak” to be applied to the size of the main image. (more…)

“Level out” the volume of our MP3 library with MP3Gain

With the brief advice today we talk about music, or rather how to simplify a perennial problem of those who have a wide libreria MP3 in which each track is ripped to a different volume.

How many times has it happened to put our MP3 player playing and having random every time tinkering with the volume because a song “save“, and the other does not feel? The solution is, and is called MP3Gain. MP3Gain is a program open source whose sole purpose is leveling (the technical term is correct “normalize“) the output volume of an audio file. (more…)

FocusWriter: a text editor, for those who are too distracted

FocusWriter is a program designed to those who want or need to sccrivere, but he can not disrarsi. It is open source and available on the net for all operating systems. Sometimes you need to necessarily produce texts, that are the thesis, the pages of a novel o la shopping list, and at any time we run the risk that some Gmail notification, a icon too attractive or simple computer menu manage to distract us from the main job.

The best HTML editor for non-commercial Linux

Anyone who has ever tried to create piagne HTML with Linux you will certainly clashed with the lack of WYSIWYG software developed ad hoc for our favorite operating system. Fortunately, today this “gap” is filled only in part due to the development of some open source programs that attempt to compensate for the lack of development in Dreamweaver (or still commercial alternatives) su piattaforma Linux, but in many ways we are still far from having reached the usability of Dreamweaver or similar.

Today we see some of the best software for the’editing WYSIWYG developed natively for Linux. Thank you the blog web distortion translated for the advice that I report below. (more…)
