Today opportunities
During the last two years the number of free online University courses exploded on the web. Today it is possible to attend prestigious courses by important USA and UK Universities and receive a final certification without spending a cent.
The good news are that these courses are interesting, well structured and you have a real possibility to increase your knowledge if approach them in the right way.
The first time you look for the free online University courses you are disoriented by the number and the many different topics they cover. The problem is to make the right selection in order not to waste time and energies for something you (and you career) don’t actually need.
How to select the right courses
1- Make a first selection between courses choosing only that are really interesting for you
2 – Check if you will receive a participation certificate if you complete the course
3 – Honestly evaluate your real, deep, interest for the courses that will not provide any written certification. I mean: “Do you really think that they will increase your knowledge and will be determinant for your career or life?”
4 – Don’t overestimate your capacities. Read very carefully the required background to attend the courses
5 – Don’t underestimate the time you need to attend the courses and do all the “homework” and the suggested readings
6 – Finally, select two (or more) courses and “Create” your free aside University career. Try to choose courses that have logical and “career path” connections between them. The important thing is what you are really learning on particular related topics you consider important for your career, not the number of disordered certification you can write on your resume.

If you are a fan of the design proposed by Apple for most of its operating systems, particularly Mac OS X, then there are a couple of things that you should take into consideration and some simple steps to follow. Therefore, you are advised to read the following information carefully in order to achieve the expected outcome in the shortest time.
There are two free pieces of software that can transform your Ubuntu desktop into one that looks identical to the one of Mac OS in no time. The Ubuntu version is called Macbuntu. First of all, you will need to install this program onto your local hard drive. Here is what you need to do for this step:
– If you are using Ubuntu 10.4 Lucid Lynx, you will need to open a new terminal and type the following lines into it:
$wget https://downloads.sourceforge.net/project/macbuntu/macbuntu-10.04/v2.2/Macbuntu-10.04.tar.gz -O /tmp/Macbuntu-10.04.tar.gz
$tar xzvf /tmp/Macbuntu-10.04.tar.gz -C /tmp
$cd /tmp/Macbuntu-10.04/
$./install.sh
– On the other hand, if Ubuntu 10.10 Maverik Meerkat or a similar version is installed in your system, you will need to use a different version of Macbuntu, which can be accessed by typing the following:
$wget https://downloads.sourceforge.net/project/macbuntu/macbuntu-10.10/v2.3/Macbuntu-10.10.tar.gz -O /tmp/Macbuntu-10.10.tar.gz
$tar xzvf /tmp/Macbuntu-10.10.tar.gz -C /tmp
$cd /tmp/Macbuntu-10.10/
$./install.sh
During the install process, you will be provided with the chance of choosing between different options. These are usually dependent on the different ways you wish your desktop to look like. Most of the choices will be based on your visual tastes, so make sure you choose according to them.
Finally, whenever you need to uninstall this special package for some reason you can follow the same procedure described above, with just an exception. Instead ./install.sh you will need to use the ./uninstall.sh command.
Conky is one of the most powerful and versatile system monitors for Linux desktops. It allows you to monitor and display all the information about your hardware, top processes, network, emails and more. At the moment more than 300 different feature has been built for Conky and searching on the web you always find the perfect feature already developed by someone.
– Installation on Ubuntu:
in Terminal run: sudo apt-get install conky

Save a copy of the original conky.conf in another location and open the original file with Gedit Text Editor
First of all change: own_window yes to own_window no
Choose your preferred alignment (some samples below…):
alignment top_right
or
alignment middle_right
or
alignment bottom_right
Play with: update_interval 1.0
and change the interval value till you find the right ratio to obtain the best speed for you (in my case it was 0.80).
Add this line to eliminate any flickering:
double_buffer yes
but, on some computers, all the icon on your desktop will be hidden and you need to use (move) the mouse to discover them if you will not add this parameter: own_window_type normal
Add, as last line (or in other position if you prefer):
${color red} ${cpugraph} to have a clear graph about cpu (obviously you can choose the color you prefer)

Sopcast represents one of the most popular technologies for live TV streaming, being based on the famous p2p system. However, until recently, there was no version of this software for Ubuntu and Linux in general. But now every single user can enjoy live TV right on their desktop or laptop computer with this absolutely amazing program.
In order to install Sopcast on your machine, here is what you need to do:
1. Open a new terminal. This is a classic step and is used in most of the installation processes you will encounter in Ubuntu.
2. In order to add Sopcast to Synaptic (the package administrator software integrated into Ubuntu) you will need to type the following command:
sudo add-apt-repository ppa:jason-scheunemann/ppa
3. The next step is related to the update of the sources list. This can be done with the following command, which needs to be typed into the same terminal in order to achieve the right effects:
sudo apt-get update
4. Now you will need to run Synaptic in order to finalize the process. This is usually done through the System menu (System -> Administration -> Synaptic). Alternatively, you can use the following simple command:
sudo synaptic
5. Look for the Sopcast package and install it. A very important step at this point is to not forget about all its dependencies. If you do not install everything, then Sopcast will not run correctly or not at all.
This is basically all you need to know if you want to install Sopcast on your machine. Whenever you need to run the player you can find it in the Application menu -> Multimedia -> Sopcast. You will surely enjoy the great variety of the channels available for every user through this system.
The following system recovery tools will be useful to you if you are facing problem of data loss or if your system is simply crashing. It is advisable to burn copies of these tools much before any disaster strikes.
Open Source and Free approach:
G4L aka Ghost for Linux is one of the system recovery tools that is mainly a cloning and hard disk and partition imaging tool. This tool is similar to “Norton Ghost”. The images created are compressed optionally and transferred to a FTP server instead of opting for cloning locally. Ideally, of the several tools described above it is advisable to use the most suitable tool for your needs. The tool that will be most useful during a crisis like a crash or server failure will be a better tool.
The Ultimate Boot CD is one of the system recovery tools which will be very helpful when you want to run CDRom-based diagnostic tools thereby consolidating as many diagnostic tools into one bootable CD as possible. Since you can now boot from USB memory devices a script you can run “Ultimate Boot CD” from USB memory stick and a script on the script on the CD will enable you to boot newer systems from your USB sticks. This is many steps ahead than many of the other recovery tools. Moreover it gives you the flexibility of booting your system with a USB memory stick.
Knoppix is one of the system recovery tools which is essentially a bootable CD with GNU/Linux software. It ensures automatic detection of hardware and supports a wide range of devices like sound cards, most of the graphic cards, USB and SCSI devices and other peripherals. It can be used as an educational CD, a Linux demo or for system recovery purposes. Alternatively it can be used as a commercial platform for software demos. There is no need to install anything on the hard-disk as the CD is capable of storing 2GB of software installed in it. Thus this tool is a truly multi-purpose recovery tool.
Proprietary solutions:
O&O Disk recovery: This software tool scans every portion of your hard-disk, digital camera or memory card for lost files. It is so effective and reliable that it is possible to reconstruct data even when files systems have been destroyed or formatted. More than 350 types of files like music formats, word documents, movie, graphics, Excel workbooks, photo and access databases can be recognized, reconstructed and restored.
SuperDuper is one of the system recovery tools makes recovery effortless as it creates a completely bootable backup effortlessly. The strengths of this software are that it is user-friendly, easy to use with a built-in scheduler that it makes backup automatically. Moreover it performs well independent of the processor that is both on Power PC Macs as well as Intel PCs. It is particularly useful when your software application with the latest update is not working or when your hard drive begins to make noise. It is also very handy when you want to restore a stable copy of your system though you do not want t lose your existing system files or cases like this. 
Several open source tools have evolved in the past and have become popular with the developers too. These tools have gained popularity not only because they come free but because of the ease to work with and the features. First let us see some code editors:
– Aptana: It is a free, JavaScript focused development environment, cross-platform and open source for building Ajax applications. It supports HTML, JavaScript, CSS languages, FTP/SFTP and has a powerful JavaScript debugger that can help in troubleshooting your code.
– Eclipse : It is an open source software framework written mainly in Java. It is an integrated development environment consisting Java development toolkit (JDK) and compiler (ECJ) for developing applications in Java. Developers can extend its capabilities by installing plug-ins such as development toolkits for other programming languages written specifically for eclipse software framework. Language packs for over a dozen languages are available.
– JEdit : It is a programmer’s text editor which has many hundreds of man-hours of development behind it. It is a java-based solution and a cross-platform product which can work on many operating systems like Windows, VMS, UNIX, OX/2 and Mac OS X.
– NVU : It is a web authoring system for Linux desktop users, Macintosh users as well as for Microsoft windows and is a competitor for similar products like Dreamweaver and Frontpage.

– Configure Wine first and add Kindle for PC as an application and make it run in Windows 98 mode
– If it won’t work, change to other mode
– When it opens successfully you have to input you Amazon email add and password to register the software.
But, please, don’t forget that if you prefer open source software, you can directly use Calibre, a powerful free software we posted a while ago.
En estos días he estado buscando un programa que permita hacer Copias de Seguridad y que sea de uso practico, sencillo y muy intuitivo. Después de ver varios programas me he decantado sin lugar a duda para LuckyBackup. Para instalarlo es posible directamente desde los repositorios de nuestro sistema (Ubuntu y derivados) o directamente desde su propia Web y bajar la ultima versión 0.4.4 . Yo he instalado esta ultima versión y tengo que confirmar que es el mejor programa de Copias de Seguridad que he encontrado hasta el momento. LuckyBackup es muy fácil de configurar y permite efectuar diferentes sincronizaciones y mantener a salvo nuestros datos y todos los archivos. También he echo diferentes pruebas pasando carpetas a memorias USB, Disco Duro Externo y Disco Duro Interno, todo sin ningún problema (Descarga LuckyBackup).
