[Firefox4] New Add-ons Manager

If in the previous article we talked about the improvements at the start of Firefox 4 (something required by many users), in this case we talk about something very dear to Firefox since its inception, and are merely accessories. But we will not specifically mention supplements, if not add new manager coming in the new version of Firefox, redesigned and with more features.


Firefox has had since its inception extensions (later as "complementary"to include the issues) that were installed in a very easy and fast. The problem was to find some extensions was not so easy. This was resolved with Firefox 3.6, which included a Search tab in the same window Add-ons (accessible via Tools> Add-ons).

New Add-ons Manager

But in Firefox 4 has tried to change this trend, it opened a new window to manage add-ons, so that this version will open a new tab for the administration.

To open it, you must go to Tools> Add-ons in the same manner as in the current Firefox on the left part shows the buttons:
  • Get supplements: shown on the right a home page that redirects ons Mozilla Addons. Find supplements has never been easier.
  • Extensions: You can manage all your extensions, preferences, uninstall, disable them, check for updates, installation date, and if you double click (or you click on the "More "), you'll see information about the plugin. Also, if you look at the catch, you can see if the extension is compatible with your version of Firefox, if you are disabled or have a security problem ...

  • Themes: here you will see listed all the themes/people you have installed.
  • Plugins: As with the themes and extensions, here you see all the plugins you have installed, such as Flash, Google Earth ... You can also disable that interest you (like Java, which has moved from Firefox options to the manager .)

(You may have other options such as "Language" or "Updates" will depend on your current configuration, although the "Update" will give you the solution, a bit below)

As you can see, everything is much clearer, and what is important, on the same screen navigation of Firefox, without opening new windows. And if you noticed, the navigation bar automatically hides when managing allowances, to ensure greater clarity that is not a website. But that's not all, as there are more things such as:
  • Menu options (which is a gear on top, next to the search box): It can make different choices with supplements: As for updates, view a history of updates, install a plugin from a file your local disk (although you can do this by simply dragging the file to Firefox), and then an option to automatically update supplements (we recommend you have it activated, it displays a check mark, the benefits described below).
  • Search Box: You can type the name of the plugin directory you wish to search and will show a results list, simply find the one you want and click Install. You can see the progress. And anticipating a bit of other articles, there are extensions that do not need to restart your browser and you can use them at the same time.

It added that in this new version of Firefox add-ons, supplements are updated automatically in the background and at any time without interrupting your browsing, not as in previous versions of Firefox, which is only updated when you start the browser, displaying a new window you could not sail until these updates finished.

Add Buttons for New Folder, Copy, Cut, Paste and Delete to the Nautilus Toolbar [GNOME]

Although I am particular to use keyboard shortcuts, I always thought that all graphical interface should have the necessary visual elements to make every user's work more productive.

In the case of Nautilus, the default file manager in GNOME, I feel your toolbar lacks basic functionality : Create new folder, cut, copy and paste files and elimination (to trash) of themselves.

To me understand better what I want is to change this:

to this:

Thanks to the great freedom that Linux offers, we can add these buttons so very easily, without needing to install anything (like typical patches and hacks in Windows), just modifying the text file nautilus-navigation-window-ui.xml found in the folder /usr/share/nautilus/ui/.

First, we will support the file in question, so we can easily recover our original settings if something comes out wrong (never forget Murphy's Law).
  • cd /usr/share/nautilus/ui/
  • sudo cp nautilus-navigation-window-ui.xml nautilus-navigation-window-ui-RESPALDO.xml
ow, with your favorite text editor (vim, nano, gedit, etc), open the configuration file:
  • sudo gedit nautilus-navigation-window-ui.xml
At the end of this file, which are specified which buttons appear in the Nautilus toolbar, through statements <toolitem name="..." action="..."/>; as a separator for each button is used <separator/>.

To add the buttons you want, just have to paste the following statements in the position we most like:
  • <toolitem name="New Folder" action="New Folder"/>
  • <toolitem name="Cut" action="Cut"/>
  • <toolitem name="Copy" action="Copy"/>
  • <toolitem name="Paste" action="Paste"/>
  • <toolitem name="Trash" action="Trash"/>
You can use spacers if you like. As an example, so I moved my buttons:
  • <toolbar name="Toolbar">
  •     <toolitem name="Back" action="Back"/>
  •     <toolitem name="Forward" action="Forward"/>
  •     <toolitem name="Up" action="Up"/>
  •     <toolitem name="Reload" action="Reload"/>
  •     <separator/>
  •     <toolitem name="Home" action="Home"/>
  •     <toolitem name="Computer" action="Go to Computer"/>
  •     <separator/>
  •     <toolitem name="New Folder" action="New Folder"/>
  •     <separator/>
  •     <toolitem name="Cut" action="Cut"/>
  •     <toolitem name="Copy" action="Copy"/>
  •     <toolitem name="Paste" action="Paste"/>
  •     <separator/>
  •     <toolitem name="Trash" action="Trash"/>
  •     <separator/>
  •     <toolitem name="Zoom" action="Zoom"/>
  •     <toolitem name="ViewAs" action="ViewAs"/>
  •     <toolitem name="Search" action="Search"/>
  •     <placeholder name="Extra Buttons Placeholder">
  •               <placeholder name="Extension Actions"/>
  •         </placeholder>
  • </toolbar>
Saves changes and exit your text editor. Finally, we must restart Nautilus for the changes are applied.
killall nautilus
That's it!

The procedure mentioned I've tried in ArchLinux and Ubuntu, so I can infer that also applies to any other Linux distro you use a recent version of GNOME.

How to uninstall Mono of Ubuntu 10.10 Maverick Meerkat

With the advent of Synapse, many of us can happily dispense with Mono on our team, because the only thing that was tied to Gnome-Do, which is an excellent and useful piece of software but has the great sin of being developed under the Mono framework.

Since we will not use more Gnome-Do, and Tomboy will probably not use since there are other alternatives as good as Gnote for example. Let's get rid once and for all Mono in Ubuntu 10.10 Maverick Meerkat.

For this, we need only execute the next line in the terminal:
  • sudo aptitude purge libgdiplus cli-common libmono*
We now have Ubuntu free from evil influence by Microsoft and not have to deal more with these heavy and poor libraries based on .Net .

: If using Banshee or Docky, you can not uninstall Mono, as Banshee and Docky are also developed under this framework.

The best way to access to virtual machines of VirtualBox

For those who use VirtualBox is a bit cumbersome having to open and close the application every time we use one of the virtual machines we have installed.
indicator-virtualbox just all this and gives us the ability to access a virtualized machines quickly and efficiently, without running VirtualBox for it. Also has a nice logo Mono style that looks great with the new issues of Ubuntu and many others.

We just need to do to install this applet is to add his PPA repository developer has arranged Launchpad Astrapi and install the application.

To do this, run the following lines into the terminal:
  • sudo add-apt-repository ppa:michael-astrapi/ppa
  • sudo apt-get update
  • sudo apt-get install indicator-virtualbox
Once you've installed the applet you just have to run with Gnome launcher (Alt+F2) or using a pitcher like Synapse or Gnome-Do and write this line indicator-virtualbox.

Convert mp3 to ogg and vice versa on Linux

First of all let me say that conversions from mp3 to ogg or from ogg to mp3 always generate loss of sound quality, most of the time will be imperceptible to the human ear but are warned.

In general there are 2 ways to convert a single file if you want to convert it then it is easier to convert the audio file from the console, so:

Convert Mp3 to ogg
  • mp32ogg –quality=10 –delete –rename=%t /home/Musiques/file.mp3
For this we will have to have the package called mp32ogg (search repositories)

Convert Ogg to mp3
  • ogg123 -d wav -f – file.ogg | lame – file.mp3
We will have to install the packages ogg123 and lame


Now, if the idea is to convert many files the best and fastest is to make using the program soundconverter. This program must be assembled together packages and lame vorbis-tools to work well. It is a simple interface where you simply look for input files and then click "Convert ". All preferences as the output format, quality, etc, are set Edit->Preferences

I hope you learn this info

How to check the MD5 of the CD of Ubuntu

In each of the tutorials I've done on the installation of ubuntu there is always some rookie that goes wrong ubuntu cd and then have problems because of that. Before recording a CD with the ISO of ubuntu is always preferable to do a verification of whether this cd is lowered it or not, that we did verify the MD5 sum of the cd.

Before doing the proof we know what the MD5 of the distro you're using, so they are going to this address: http://releases.ubuntu.com/ and look for the folder you're using distros. Within it there is always a file called MD5SUMS and in the same browser opens a page where we see the MD5 of the different alternatives of ubuntu (ubuntu desktop, ubuntu netbook, ubuntu alternate, etc).

And that number we have to compare the MD5 sum of cd, that we get a console by typing the following:
  • md5sum nombre_del_cd.iso
Compare two numbers, if they match the download was successful, otherwise .... touches down again

Like I always recommend installing ubuntu from a pen drive to save a cd.

Install Ubuntu Tweak 0.5.9 on Ubuntu - Update Now

A couple of days ago they announced the availability of version 0.5.8 of Ubuntu Tweak with support for Natty.

There is a major bug in this version. In the Preferences menu if you select the option Use separate sources have no problems and just update.

In the event that you uncheck this option, most likely you will have lost all sources of the Launchpad PPA.
But quiet, has a solution. First upgrade to version 0.5.9 with the deb package for your version offered here.

Then open a Terminal and run this line:

  • sudo /usr/share/ubuntu-tweak/merge_sourceslist.py
Done. With this, your sources should be restored.

Also say that this version updates some languages.

Create a Facebook profile Creative easily

Since the start of the new Facebook profile, just someone you happen to do something creative for the profile, to quickly begin to move Photoshop tutorials and templates for more users to achieve something similar.

Today I discovered an amazing application that does everything for you, saving you the cumbersome manual process.

Application is called Profile Maker, where all you have to do is follow three steps: Upload your picture with the [+ Upload Photo], fit (using a simple drag and/or zoom), and finally click the button to [Create Profile]. Application will create a new album with the images created.

The only additional manual step is to select the main picture (the vertical rectangle), and set it as profile photo. That's all! No need to be a graphic designer for a creative profile on Facebook.

Android now use the Ext4 file system

With the advent of new Google Nexus S, Android reaches version 2.3 (Gingerbread), And with it the use of powerful and popular file system Ext4.

Ext4 file system is currently used in most modern distributions Linux, And it is considered quite stable and secure with minimal risk of data loss. Not for nothing Google has migrated its entire server infrastructure (the largest in the world) Ext2 to Ext4.

Most current devices with Android use the file system YAFFS, Which despite being lightweight and optimized for storage in memory flash, Has the problem that only runs one process at a time, which eventually cause bottlenecks in concurrent dual-core systems, the next generation of devices Android.

The developers of Android applications should have no problem with this change Ext4, Provided they use the API High-level storage, which is absolutely secure. If despite this, developers directly access the file system should only be careful to hold time information in the buffer time (a basic and essential feature Ext4), Preserving the data persistence.

Indeed, there are no immediate plans to implement the file system Btrfs (From Oracle) Because it is not yet considered mature enough to be used at production level.

Picapy, an application to access to Picasa from Ubuntu

[Firefox4] Improved boot

Admittedly, Firefox browser has always been slow to open, improving with each version (though the reputation has been there, as the memory consumption, completely false) but no match newer browsers such as Safari or Google Chrome.

But Mozilla is stepping up in this new version, conducting a series of important changes to improve startup, And the user less noticeable delay between you click the icon and your browser is fully functional.

A bit of history. Firefox has a structure, in which each starter had to open different files .Jar (Which are ZIP files, such as tablets, but without compression. We could describe them as a simple container of files) but had its limitations. Above all, I had to open files within the folder "components"They are like modules (private browsing, cryptographic, synchronization, session ...). And these were separate files, so I had to open hundreds of files in total, and one of the assumptions about computers is that reading is extremely slow hard drive (compared with other operations). Therefore, the less read, the faster we will finish the boot.

Omni.jar comes solve this. Since it is a file that packs most of the startup files, making reading a single file and removing them in the memory via CPU (the CPU usage is tiny compared to the time to read several hundred files), which greatly accelerates the boot. In addition, this file format is ready for more optimizations (Read first the first thing you need and go use it and continue reading another thread with more files, so that the boot could be even better.)

According to MWU developer an article, We read of 259 files only 61, a 76.4% lower files.

Extensions without decompressing
If you look at your profile Firefox (3.6 or earlier) you'll see a folder called "extensions"That if you enter you can see normally a series of folders with names or numbers and letters completely indecipherable. If you open any of those folders you'll see that this is an area that has ... more files! More files to be read when you open Firefox, which can make a slower start.

Then, the developers thought ... if when you install the extensions download a single file, why not leave it as such and use the same with omni.jar ,Opening the file on the fly at boot? (Remember, that the CPU usage unzip a file in memory is paltry compared to having to open dozens of files on a hard drive).

And that's been made. In most of the extensions you install in Firefox 4 (there are some that need to be unpacked) you'll see file .Xpi instead of a directory (actually, this directory would be decompression .xpi now in packet mode. And yes, again .Xpi is very similar to .Jar, File .Zip uncompressed).

This is another point in the boot time, we already have two, but very technical, go to a more visible.

Style tabs BarTab

In Firefox 3.6 and earlier, when it reopened a session in your browser and you had dozens of tabs saved from your previous session, what happened is that all were loaded and did all the time, So you usually had to wait several seconds until you saw the browser window and began to respond appropriately to what you asked.

This has changed in Firefox 4, taking the idea of a great extension called BarTab (one for Firefox 3.6 and above, in case you want to test.) What is now Firefox is: when you open the browser and you have many tabs, load priority tab is selected (Either the first, last or whatever) and also charge only 3 tabs (Default) more, So the response is larger.

For the hands: the preference to change this is browser.sessionstore.max_concurrent_tabs within about:config. If you put 0, only load the currently selected tab, the other will not load until you click on it. If you put a value greater than 0, charged at the same time the number you've put: 1, 2, 3 tabs at once ....

As you see, things have been done to improve the boot process, to be faster (have been things in the pipeline, such as better use of memory allocations, newer compilers, further optimizations, using newer software such as SQLite ), but what are these 3 main points discussed in the article, which we hope will be (especially the third) the longest you better start.

Ubuntu 11.04 and the audio menu

The latest version of Ubuntu, and came with significant improvements in the audio menu, which as you know no one can control the system volume, but also gives access to control the current playback (Also showing the cover and track information) if we use a player that supports this feature.

The technology behind this function is called MPRIS or Media Player Remote Interfacing Specification. This D-Bus interface allows us to offer an API with which to add remote control functions for multimedia players, and is already available the second version of this interface, called, of course, MPRIS2 (or MPRIS 2.0).

The interesting thing about this second specification is the fact that we will be able to access controls on a bunch of player applications, but Internet services also are compatible with this technology. For example, Spotify, which still does not have a native client "complete" in Linux but many users still use their premium accounts (for native version) And through WINE (for Spotify free version).

One of the managers of that MPRIS2 integration in Ubuntu 11.04 Natty Narwhal now how this development has is booming ,and how you can start testing the work done so far available through the project in LaunchPad.

In my opinion the best audio menu of Ubuntu 10.04 was possibly the most important interface of the system: not having to jump over and over again to the player, whatever, is really comfortable, so I think it's great to continue working in this area to further enhance support for new players and Internet audio services.

Oracle released VirtualBox 4.0, care license change

Sun bought the company and its entire catalog takes a few months time updating VirtualBox, It seems clear that at least in this section the template and the team responsible for the development of virtualization still very active.

Now is the announcement of the availability of VirtualBox 4.0, A desktop virtualization application for different platforms to x86 architecture which remains one of the clearest references in this segment: I use VirtualBox to test very often curious Linux distributions that do not want to install natively on my computer, and the truth is that the behavior of the application has always been fantastic.

In Oracle indicated that the new application makes the leap to the family with version 4.0.x Improved user interface ,as well as additional support for virtual hardware, including chipsets that support PCI Express. Other changes include increased capacity and throughput supported by the use of a new asynchronous input/output model for network storage (iSCSI) and local, as well as better support of standards called Open Virtualization Format (OVF).

For the first time both the source code for Oracle VM VirtualBox as binary code and hey are licensed under the GPLv2, While the mechanism Extension Pack, which allows third parties to add their own features, is licensed under PUEL.

What does this change? For distributions that include the Open Source Edition (OSE) VirtualBox no longer have to compile the application from source themselves, something interesting to integrate this fantastic development in the distributions of native form, although alternatives are very strong in Linux, especially in the case of KVM.

You can consult the official announcement -Which interestingly links to a blog of the former Sun network that is ongoing- and changelog traditional version, and can also Download the latest edition from Official Website of this development. If you are a Ubuntu user in UbuntuGeek have issued instructions to easily install the application by adding specific repositories for Ubuntu 9.10, 10.04 and 10.10.

Firefox 4 Beta 8 available

Mozilla has released a new Beta version of Firefox 4, and while theoretically it would be a minor update to the earlier draft, the final will have fixed a bunch of bugs: up to 1,415 different corrections. all here.

Mozilla is planning with some delay, and in fact remains to reach a Beta-9 is already available as a nightly build, which will not arrive in time for 2010. However, this Beta 8 Fixed a heap of problems with Beta 7, Many of which affected the stability and functionality of the browser base.

According to the release notes, Firefox Sync has been simplified and is easier to configure ,and even you may also be available on mobile devices with versions of Firefox for smartphones, also known as Fennec.

Also in this version we find a more elegant ons manager and visual ,and a support accelerated WebGL which makes the possibilities of having animations and 3D games built into the browser will increase dramatically.

Now you can download Firefox 4 Beta 8 from the official website of Mozilla, and it is less for the final version!

Six Linux distributions that made a difference

Nowadays you can find Linux in the strangest places: Robots, refrigerators, cellular, media players, Several servers ... and even computers. Of course, the system has not yet mastered the penguin in the area of desktop (and it is likely that this will not happen anytime soon) but he is gaining more and more users every year, and being recognized as a great alternative to Windows and Mac OS . It was not always so: Linux has a long way to go hundreds of distros to reach its current state.

Many distros have been created in recent years, and there were few who directly or indirectly, have made a real difference. Is bringing a new concept, or a functionality that simplified the user's life, these distros helped popularize the concept of open operating system. And these are some distros that comment below, even as a form of tribute for all the help they rendered to the community.

Of course, I bring the list below is based on my personal experience, And should not be regarded as the definitive list of anything. If you did not like any summons, or think you missed a distribution, the comments are open.


Until the birth of Debian in 1993, the Linux distros were totally customized by the developers and allow a few modifications, in addition to forcing users to wait for a new release or download and compile new versions of programs if they wanted an update. With Debian, things began to change, users need only install a piece Basic system, and all the customization (including new packages and updates) would come across several repositories on the Internet. With the popularization of the Internet and increased access speed, this model became a standard in many distros. And, as Debian is a lean system, it is very common to get a new distro from it, as is the case next distro.


Until the creation of Ubuntu It was very common to hear of Linux as a robust system for servers, but rarely for users who do not have at least some experience with computers. Distros like Mandrake, Conectiva and SuSE even tried to sell as alternatives to Windows, but with Ubuntu was that the concept of user-friendly really came to Linux.

Today an Ubuntu user rarely needs to open the terminal or run a command line to install a program or make some configuration in the system. Even 3G phones rarely need to be setup in many cases just stick the USB cable or connect the phone via bluetooth is already recognized as a modem and you can already connect. Some tasks, moreover, are even easier in Ubuntu than in Windows.

Red Hat

The Red Hat (Which today is divided into two distributions, Fedora and RHEL) was the first Linux distribution to draw the attention of companies. With a more sober and customizations aimed at the corporate market, has long been common to hear of Red Hat in the enterprise, both on servers and desktops.


You know when you just poke a stick or put a CD in the drive, restart the computer, and already have a Linux distro ready to use without even needing to install something on your computer? So the concept of Live CD became popular with the Knoppix, A Debian-based system that used KDE and allowed to run a system full of applications from the CD.

Until then, try a Linux distro without removing the Windows partition the HD involved, insert the installation CD, 56 times to review all the settings of partitions, and then reboot discover that the distro was not the driver for your network card/sound/modem/video/mouse/hd/monitor/whatever, making installation a dead weight on the HD. With the concept of Live CD, even the presentation of the system to friends and relatives became simpler: just to boot, asking him to test, and then restart the computer. And Windows still there.


Knoppix was cool but had a horrible defect: beyond the language that should be downloaded from the Debian repositories. It was from the Kurumin, Distro that was originally a one-man, developed and distributed by Carlos Morimoto, who might have a Linux distribution with live CD entitled adapted to our problems.

Not incidentally, he quickly gained popularity and was the basis for many distros.A pity that, for various reasons, has died early.


Toward 2005, quality system for mobile phones only had a name: Symbian. At the same time, a startup called Android turned to how he could develop a mobile operating system that was based on Linux.
