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.

Inkscape is an open-source SVG editor with capabilities similar to Illustrator, CorelDraw, Visio, etc. Supported SVG features include basic shapes, paths, text, alpha blending, transforms, gradients, node editing, svg-to-png export, grouping, and more. Its main motivation is to provide the Open Source community with a fully XML, SVG, and CSS2 compliant SVG drawing tool.
These are the founding goals for Inkscape:
– Full SVG (plus XML, CSS2) compliance
– Core written in C/C++
– Gtk-based user interface following the standards set out in the GNOME Human Interface Guidelines (HIG)
– Emphasis on a small core and extensibility. Usually Inkscape’s extensions are always first-class so we can say “no” to features in the core without guilt.
– Open, community-oriented development processes
– Baseline is the Sodipodi Hydra codebase
Where a better solution cannot be found, default to the way Illustrator does it.
Probably the easiest way to install on Ubuntu is to use the apt command.
Open a terminal and type;
sudo apt-get update (enter)
sudo apt-get install inkscape (enter)
As it approaches release, nightly i386 and AMD64 builds of the latest Inkscape development version are provided at http://ubuntu.cafuego.net. On that site, one should select the appropriate Ubuntu or Debian release, then the Inkscape link, and finally the provided package. 
To enable remote desktop on a VirtualBox machine, you have to follow these steps:
VBoxManage modifyvm MachineName -vrdp
This command enables rdp on the virtual machine
VBoxManage startvm MachineName -type vrdp
It starts virtual machine, listening for rdp request on port 3389 (default port)
rdesktop-vrdp localhost
Connects virtual machine with rdp (You can use rdesktop too).
If you want to change rdp port, use this command:
VBoxManage modifyvm MachineName -vrdpport
Also, enabling authentication for rdp is possible:
VBoxManage modifyvm MachineName -vrdpauthtype null | external | guest
VBoxManage is the command line interface of the VirtualBox.
You can make these settings with GUI: Settings -> Remote Display -> Enable VRDP Server
If you want to use your virtual machine with vrdp only, you can use this command simply:
VBoxHeadless -startvm MachineName
Note: RDP server is not included in Open Source Edition of the VirtualBox. If you want to use this feature, you have to use closed-source edition.
Hace unos días tuve un problema con mi Kubuntu 10.04 y la conexión de red. Cuando fui por apagar el PC, en lugar de apagarlo le dí a hibernar por error y cuando fui otra vez a encenderlo no tenia conexión de red disponible. Mirando en el icono que informa respecto a la conexión de red tenia un único mensaje que decía: Gestión de Redes Desactivada. Por tanto que yo intentara de buscar la forma de activar el gestor de redes, no encontraba nada y ninguna opción disponible. Después de varios intentos tuve que ponerme a buscar en la Web con mi portátil para ver si encontraba la forma de solucionar el problema. Afortunadamente encontré que el problema surge en cuanto se apague el PC de forma instantánea o como en mi caso por hibernar, por esos motivos parece que NetworkManager no borra el archivo de estado y cuando se vuelve a reiniciar el PC se genera este error. Para solucionar el problema hay que escribir una serie de comandos en el Terminal para borrar e archivo y volver a reactivar el Gestor de Redes. Os añado las líneas de comandos porque puedo garantizar que es una solución realmente efectiva:
sudo service network-manager stop cd /var/lib/NetworkManager/ sudo rm NetworkManager.state sudo service network-manager start
After my last update I was not able to visualize my upper panel on Ubuntu 10.04 Netbook. After some internet searches and tests I found these two solutions which were useful to me:
Solution A
– right click on the background and choose Change Desktop Background
– go to Visual Effects and click on Normal
Solution B
– ALT + F2 and when in Terminal type
gnome-panel
If you want to save the configuration and visualize the upper panel for the next time you use Ubuntu, please type in terminal:
gnome-session-save
I am sure there are better ways to solve this problem, so if you have suggestion you are free to comment this post. Thanks.
