Sometimes, some conflicts in keyboard shorcuts can drive you nuts ! After reading dozens of forum discussions about this subject. I have found the solution in this link.
Actually, you need to change the Ibus keyboard shorcut (control+space) so it doesn't "eat up" your magic shorcut on Eclipse.
Matlab is a very reputed piece of software specially among researchers and graduate students. It allows users to code complicated algorithms thanks to its rich libraries that implement many mathematical functions and statistical models. You may have ever used it to implement some classification processes that deals with heterogeneous data and you have got some interesting results and you wanted to show it to a client. He may not be interested in your statistical model nore in your charts and graphs. He is interested in a beautiful application with an ergonomic user interface with big shiny buttons that allow him to use you piece of program. He is interested in the usability of your program more than the academic process that allowed you to get your result.
So to make this happen, you need to implement a simple prototype that calls your Matlab functions and show resluts in a simple GUI. If you're a Java savvy, or you prefer java to make this happen you need to use the MatlabControl API. It's a simple Java API that allows you to call Matlab functions and execute eval, feval and other commands.
All you need to do is to download the jar file and add it to your classpath and use this code to open a Matlab session.

Currently, computer networks are the backbone in the remote communication. Now they have become essential for the proper functioning of many domains and applications. Their rapid growth induces increased complexity of administration tasks and fault detection. Any problems or failure may have serious consequences forcing the use a system of monitoring and alert management.
The network monitoring has become therefore a major task not only the ensure the system retention and good functionality but also to have a global view on problems that may occur to prevent their appearance. As the task of the administrator is to ensure the smooth functioning of its network and manage heterogeneous devices, administrators were then forced in the past to work on a machine connected to the network which makes their task more difficult and may risk delaying critical tasks. Thanks to advances in technology and the evolution of the Web, this monitoring task has become more flexible.
In fact, the administrator is now able to monitor its network remotely via a web application that provides network monitoring and is capable of describing its condition and report alerts when this is necessary. Hence, it can remedy problems and resolve them as quickly as possible.
Indeed, this application starts with the automatic detection of network equipment (Routers, firewalls, terminal) which allows to draw the map showing equipment found to give the administrator a clear view on its network. The administrator can also predefine the annoying problems that which he judges to be important to be notified when they occur. Once one of these problems is encountered, an alert will reported to the administrator to inform him about the problem detected, its severity and its location so that he becomes able to correct it immediately.
The main objective of this project is to develop a web application for network monitoring and effective management of alerts. This application should be able to monitor services and network resources (routers, terminals). The following video is a demonstration of the project.
EXT JS is a javascript library which is build to offer web developers the ability to make interactive web applications using Ajax, DHTML and DOM scripting.
The new tendency in the last deacades in software development is the "rich Internet application". To be close to desktop application, you should have some advanced web
graphic tools and frameworks. Extjs has all the features to allow you to develop your rich Internet application.
The predefined tools such us grid, forms, panels and menus are rendered client-side.You don't have to wonder about compatibility. It's designed to work perfectly on any common browser.
Coding and editing Ext js scripts is fun. Since there are many examples with the downloaded package of the library and it has a very helpful community. These are some Screeshots of what this library is capable of:
Hi... We started to study shell programming in school and we use VI to code some scripts. I noticed that all my colleagues using vi on ubuntu are very irritated and seem to envy their friends who use VI on Fedora 10 because it's very easy to use and colorful, it helps to detect syntax errors. Some of my friends started to regret installing Ubuntu instead of Fedora and even blamed me for recommending it. As an Ubuntu fan I looked for a solution for this tiny problem. I won't accept any lame remark about Ubuntu !! you need a colorful VI ? Here you are !
1- You have to install VIM which is "vi Improved" just tape this code in your console:
sudo apt-get install vim
2- After installing it you have to edit a file () and uncomment a parameter. To do so first you have to turn into root so type su and enter your root password:
su
then change this file mode for writing (so you can change its content)
chmod +w /etc/vim/vimrc
no open this file using vi if you want and uncomment syntax on. i.e erase the (") before syntax on in line 20.
vi /etc/vim/vimrc
After doing that save changes and exit using :wq try writing something, save it and re-open it and you will find your beautiful colorful script. ENJOY !!
When the machine gets old and becomes useless. You get short on options. You can't sell it because you are so emotionally attached to it and it doesn't worth that much and you can't run new applications on it because it can't afford them. But you can turn it into a beautiful workstation. Able to open your pdf documents, play your music and videos and does your office tasks... You need just a light operating system that doesn't consume much hardware resources.
I'm talking about a Linux system of course so you won't spend any dime on proprietary software and you can avoid the headaches of the anti-viruses and etc... The choice was : xubuntu .
I installed xubuntu 8.04 on my Compaq Armada notebook. This notebook is really a disaster running with WinXP but not bad with Windows 2000 and this is its configuration :
Intel Pentium III 750 MHz 64 MB Ram 20 Go hard disk
Pathetic isn't it ? But it was all I had when I needed a Linux system for my SHELL programming courses. I downloaded the Xubuntu which is an ubuntu distribution designed for low performance machines and it was just perfect. The graphics were nice and simple. Most of the applications run properly. The execution of the system in the start up doesn't take much time. You can see down here the "system monitor" and how xubuntu is using the ressources of the machine.
Actually, it was on the 25th of december. Linus Torvalds plays Santa clause and released a gift for all Linux users. It's the New Kernel.
Ext4 : The most important thing in this relase is EXT4 the new Filesystem of Linux which will be :
Compatible with the old EXT3 : you can have and ext4 partition as if you have a ext3 one.
Larger filesystem : The capacity of this FS was extended to be able to support 1 Exbibyte and files of 16 TiB ( about 16 000 Gigabytes). The number of possible used directories was extended to 64000.
Journal Checksums : The Journal (a file containing the changes of a hard disk) will be using a new technique which will improve the reliability of the disk by cheking the occurence of anyy error during the processing of saving data.
Graphic performances : The release of the new GEM (Graphics Execution Mananger). This piece of software will take care of the graphic chipset ressources and how to exploit them for different multimedia applications. This GEM will improve the graphic performance of you graphic card. Some improvments were made to KVM. It's the part of the kernel that take care about virtualisation for some architectures like intel-V and AMD-V. It will allow the machine the possibility to seperate several systems without restarting and the possibility to use some pieces of software that don't exist on the HOST system.
Drivers: Many improved drivers specially for USB and Wirless devices. The tree of these drivers was considered as stable.
As a conclusion, the new Linux has many new features. Will they be adopted by the different distributions ?
In order to find out the status of the engineer in Tunisia we will try to answer these questions:
Who`s he ? What does he do?
How much does he earn ?
What is his image in society?
What does he suffer from ?
What are the potentials of this career in Tunisia ?
Definition
An engineer is a person professionally engaged in a field of engineering. Engineers are concerned with developing economical and safe solutions to practical problems, by applying mathematics and scientific knowledge while considering technical constraints. As such, the work of engineers is the link between perceived needs of society and commercial applications. Some consider this profession to be the link between art and science.
wikipedia definition
Problems
joblessness and overexploitation :
Some statistics of a study made on 4763 young graduated students in 2005 after 18 months from their graduation
Financial status
For newly graduated engineers with no experience the wage is from 800TD to 1200TD.
After 5 to 10 years of experience the wage can touch the 1500TD to 2000TD.
Earnings mainly depends on years of experience,certifications and of course the engineer himself. Once he proves to his boss his skills and abilities, he can renegotiate his salary.
The gap between Tunisia and Europe in wages
In France, the salary of a newly graduated engineer is from 2000€ to 2800€ ( 3600TD to 5000TD).
In the end of his career, a well experienced engineer can touch 6000 € (10800 TD).
The standard of life is very different. The daily needs are expensive in Europe compared to what is available inTunisia but still an engineer in Europe is better remunerated.
The evolution of the engineer in Europe and USA is faster. In fact, occidental companies evaluate talent and take it into consideration.
The competition between these companies to have the best members in their crew make the salary negotiation more simple and efficient.
In conclusion, Tunisian engineers won`t skip the chance to travel and work abroad . Consequently, Tunisia lose many skilled engineers and this is just a sample of a wider phenomenon called `Brain Brand`.
Social status
57,2% of higher education students are female (www.universites.tn)
30% of working engineers are female(2004 statistics INS)
conclusion : The society considerengineering as a masculine job
To proceed in explaining the social status of the engineer Tunisia we will use a study made by Raoudha Ben Othmen a professor in the university of Tunis:
Subjects:
180 secondary school students aged 15-16
180 primary school pupils
Tools :
Questionnaire
Draw me an engineer test
Teacher led class discussions
N=140 Questionnaires (45% boys and 55%girls)
Drawings
No major difference between children and teenagers’ drawings.
None of the drawings contained a picture of a woman.
Most drawn engineers have glasses, are middle-aged, look scruffy wear a lab coat and hold some kind of tool.
Some pictures contained a working bench
Class discussions
Teachers seem to have naive ideas about engineers and engineering.
Teachers did not give the children the name of a famous modern engineer. Most of the examples are old (Graham Bell)
In leading the class discussions about future careers, teachers allocated more turns to boys than to girls
In leading class discussions about studying engineering, teachers seemed to allocate turns equally between girls and boys
Tests conclusions
•Students and teachers hold naive conceptions of engineering
•The necessity to enhance the image of engineers and specifically of the working environment
•Both male and female students are determined to choose other lucrative careers than engineering
Potentials
Many foreign companies choose to invest in Tunisia due to the low taxation and labor cost.
The Tunisian government aims to attain 7000 engineers in 2011-2012.
Many Mega projects are scheduled in Tunisia as ` The Mediterranean gate` which will host hundreds of companies.
Conclusion
All the figures are showing the fact of the promising future of engineering as a profession in Tunisia. However, many laws and interventions have to be made in order to protect the engineer`s rights and ameliorate his status and his image is society.
First, Let me apologize to all my readers for my absence. I was really busy lately because of an important exam that I hope I will pass. As you all can notice my blog was inactive for more than six months. My Alexa rank dropped from 500k to 2M ! My PR dropped from 4 to 2 ! ( That's hard ! ah) . My visits kept an average of 50 visitors a week most of them from google. So to fix these problems I put some steps to take :
1- Finding new content : I have to write and make some new fresh articles about the latest news. I made a tour among the E-magazines that I used to read and I found a couple of subjects that I definitely will write about. Since I was cut off from the world, I will need some time to figure out what is going on in the world.
2-Gathering old web traffic sources : Get back tou your Web analytics and open the archives of the happy days ! The busiest months and the best traffic days and find out the websites that directed to you and try to post your content in them again. Believe me it's very efficient.
3- Gathering keywords : This absence is a very good experience for my blog. In fact, I kept on having traffic from google. So it's very important to get those keywords and work on them more so you can still have traffic if you will get absent again.
4- Heavy social networking : I will need thousands of diggs and stumbles. I will use everything I can use to get the old traffic.
If I follow these steps my blog will definitely be back.
KDE4 Libraries have witnessed major changes in order to make coding KDE applications an easier task. Many shining points in this new edition which make of the future of KDE more promising.
Oxygen:
Oxygen has remarkably changed. It's the standard graphic kit of KDE, developed by KDE designers. Oxygen Includes Wallpapers, buttons and themes... You can change any theme you want but Oxygen is the standard theme of KDE4. May be some screenshots could describe better than words: (by SDZ) and here are some Oxygen designers :
The graphic library used by KDE users to code most applications. QT4 wasn't compatible with the previous editions of KDE. Now, KDE4 is using Qt4.
Qt4 will allow KDE developers to make better graphic applications. Qt library was optimized to reduce its appetite to memory and hardware resources (RAM,CPU..etc). This optimization is still not complete. Qt developers are focusing to make the use of Qt4 easier than they will continue this optimization.
Qt4 is portable through KDE. We previously explained that Qt4 was distributed under both proprietary and GPL license. From now on Qt4 will be distributed with KDE which will make it accessible to everyone.
Plasma: Plasma is a KDE library dedicated to the desktop : background, menus... Plasma was tweaked to become more personalized. You can change your desktop by adding widgets and plasmoids on your Dashboad, add RSS wires, and many other features. These plasmoids are independent from each other which makes them easier to create. You can code your own plasmoids using C++ or Javascript. Phonon:
Phonon is a multimedia library which I previously talked about ( Phonon : where Qt and KDE meet) dedicated for Sound and video. This library will allow KDE developers to include sounds and video effects to their KDE graphic applications smoothly. this is the blog of Matthias Kretz the Phonon creator.
