Darwin robot theory !

Darwin incredible! Robotics specialists based in Switzerland, have developed a simulation program that allows virtual organisms (which were the origin of real robots) to feed by collecting virtual disk to be cloned by following a process called natural. Indeed, it is robots that fit best with the right to multiply. Each "cloning", some variables change randomly, which directly impacts the robot to be emerging more or less hard to collect food. The lowest disappear. The robot is programmed to pick up a max of food to be cloned and so spread their genes.
Once well established this simulation, the researchers incorporated a new feature: The ability for robots to share their food as they wish.
According to the theory of Hamilton, a biologist of the 60s, the altruism of sharing such food with another family member would be guided by the need to propagate our genes. Whether for animals or for us if we help people who are genetically close to us, because we want to continue without knowing our genetic heritage that is in us but also within our family .
To prove this theory, our scientists Switzerland has run the simulation, and after several generations of "virtual robots", they noted that robots help each other by sharing each small disc, so that the group is a relatively equal level of food, and everyone can survive in the simulation and be cloned. If a robot gives his food to another, it disappears ... it disagrees, but he survives his "brother" dies ... etc.. Equitable sharing and mutual aid is a good solution for both personal survival of their genes and that of their families.

Why use Suse ?

- OpenSUSE is less susceptible to viruses, I explain: if no operating system is invulnerable to viruses, openSUSE (like any good Linux system) greatly minimizes the risks.
- OpenSUSE is "ready to use" plain with the DVD version all you need is already pre-integrated (office suite, graphics software, video ...)
- OpenSUSE is free; Not only version downloadable from is free but the software is free, too often this that does not spoil anything!
- The stability of the system is absolutely more to show; version 10.2 is a marvel of stability provided they do not play with the user Administrator !
- OpenSUSE is a multi-platform, yes! Unlike Windows, Linux can read files or proprietary format files typically used in Windows. And not only can he read and use, but generally it can even write in this format. A text file without any problem can be saved in Word format. Today Linux reads and writes to NTFS specific Windows!
- OpenSUSE is a fortress, where again various tests prove that Linux surpasses Windows in security and intrusion. His Firewall is powerful and set for routine use. More security holes are corrected much faster than Windows.
- OpenSUSE is free, there is more a mindset than a real advantage. The fact to receive free software or not but with a simple right be seen, copied, modified and redistributed makes this argument a force. Nothing prevents you from participating in the project and modify the code according to your needs and redistribute it without any license problem.
- OpenSUSE you do find love, well yes! By saving the purchase of avoiding expensive software or software to crack your girlfriend will happy and you can make him more gifts! And imagine the side Poetic Knight's Freedom in a Free World!

Advantages of MySQL
  1. Large community of developers (PHP).
  2. Excellent documentation. In several formats (HTML, HTML Help ...), online comments.
  3. Numerous articles and tutorials for info about MySQL, and PHP.
  4. Replication and backup databases. Managing a single master-slave replication in the case of a backup for example.
  5. Management of certain integrity constraints: Foreign Key for InnoDB tables, for example.
  6. Local database: Possibility of taking MySQL software and distribute it without a server.A bit like I think Borland BDE or SQLite (Distributed with PHP5).
  7. Transactions Management  (BEGIN, COMMIT / ROLLBACK).
  8. phpBB: The forum used by, like hundreds of other web sites using MySQL (I will like to know the size of the database!).
  9. MySQL is supported by the majority of free hosts, which is not the case of PostgreSQL.
  10. Great tools to administer your databases: PhpMyAdmin for the web by example.
  11. Simple to install and configure, deploy and maintain Windows.
  12. Good support for professionals from the only experience I have had concerning the boarding of a MySQL database software in particular. Team very responsive.
  13. The youngest is not necessarily an advantage, but more a welcome feature, LAST_INSERT_ID () to retrieve the ID, the value of the primary key AUTO_INCREMENT, the last entry inserted into a table by an INSERT. Should be used with PostgreSQL sequences.


  1. No longer used by SourceForge because MySQL did not support the load increases, they opted for PostgreSQL. MySQL is perhaps easy to install and deploy, but it does not perhaps the degree of scability PostgreSQL.
  2. Not support the standard SQL2 (92) to 100%. Actually I have never encountered problems in the writing of my queries, just take a few hours to read the first chapters of the manual and see that MySQL does not away from it all that much, except for the purists .
PostgreSQL Advantages:

  1. Legacy table: PostgreSQL is not a simple RDBMS. This is the main argument that I can progress as the only feature that I miss in MySQL.
  2. Scability: See the problem with MySQL SourceForge.
  3. All these advanced features, some developers can not live without: Sub queries, triggers and stored procedures mainly.

  1. Not available natively for Windows, it uses an emulation layer (Cygwin). Upcoming version 8 will be available natively for Windows.
  2. Can not manage a local, but I could be wrong. An expert opinion? Then we can say that it was not designed for, but opt ​​for MySQL and you get the best of two worlds, local and online.
  3. See some benefit from MySQL: Less supported by the community of PHP developers (Still need to know which category you belong), there are more hosts PHP / MySQL but the big names often suggest PostgreSQL (Can be more expensive to deploy than MySQL because most resource hungry ...).

My new frame

I buy my new frame which is the Stolen Cherry ! It weight is of 4lb 3.2oz in matte black (in full 4130 chromoly) ! It is a very lightweight and durable frame ! I love this frame !

Apache vs IIS

IIS performance advantage
Speaking of performance, in fact I compare stability, speed and lightness. And I must say thatthe speed and lightness, IIS wins hands down. On stability, is lukewarm. They are both software very stable servers, good stability and excellent stability Apache on IIS on a draw under this criterion. On speed of execution (in interpreting the PHP code of course, otherwise there would have the advantage ASP. NET is compiled), there is a clear advantage in IIS. For Apache, the tests were performed on Linux (because Apache runs more stably and more fast this OS). I even tried to optimize the best with compilers (Disaster itinerant what) and even the accelerator Uniform (known to Uniform Server). Nothing doing, IIS always has the advantage of speed, on web pages small, heavy pictures, etc. ... To know exactly where does this difference would require Microsoft We provide the source code of IIS, but the processing of each request is performed more quickly on an IIS server as an Apache server. 
Then comes the light. In general, conducting heavy requests, IIS uses 40% less Apache. This is reflected in practice by the that IIS, even on a small server, can hold very large peaks attendance, either in number or size of queries. 

Advantage IIS Security
 It is customary to say that IIS is less secure than Apache. Just as it is used to say that any Microsoft product is less secure than any other, etc ... The truth is quite different, since it also IIS which has the advantage in terms of security. More effective protection against the shellcode,attempts to privilege escalation and DoS attacks service. Similarly, management of DNS domain names is much more secure and more thrust on Microsoft software.

Draw on the portability
 Why draw? Well it's very simple, but both programs earn on different interpretations of what portability. 
Apache has the advantage of being used on many systems holdings (although under Windows, this is really not a luxury). In terms of portability in the sense of using different languages, there is clearly IIS that has a train in advance!
If Apache is limited to PHP, CGI (if it is considered a language), Perl, Python and JSP, IIS ASP pays (but that we do not care), and all the languages ​​of . NET platform (C #, Axum, C + +, etc ...), plus other goods that are compatible with!

Ubuntu 11.04

Why choose ubuntu ?

  • Freely available and freely: anyone can download free and legal copy of Ubuntu and install it for himself and others. It can also get the code used to build Ubuntu, study, modify and then redistribute (with or without financial reward) legally; 
  • Stable 
  • Not need to reinstall all the regular operating system; 
  • If rights are properly managed, users "classic" can not change anything that might jeopardize the overall stability; 
  • Secure 
  • Viruses and worms attacking mostly Windows; 
  • Customize Ubuntu theme graphics and sound individual; 
  • Always at the cutting edge: a new version every six months Ubuntu propels continuously forward; 
  • System software repositories to install in a few clicks, with disconcerting ease, extremely customizable software. The deposits contain software packages, the number rose to 23k. In this framework, we can say that Ubuntu is perfectly suited to exploit the Internet.Mirrors of the Ubuntu repository are available locally to speed up transfers. Compatibility general (but imperfect) with the Debian package allows good interaction between the two distributions; 
  • The latest security updates are streamlined and managed graphically: a task notification alerts you when an update is available. With a few clicks, your computer and your software is secure; 
  • A large community contribution: 
  • A francophone community offering documentation and active forums; 
  • Launchpad, a coordination platform to unite the international community on developments, bugs, translation (location) and the Ubuntu documentation; 
  • Linux user groups offer support Debian generally followed the same course with Ubuntu.Indeed, these two distributions are very similar and are handled in much the same way.
What is new on 11.04 ?

Major improvements Since its inception, Ubuntu is based primarily on GNOME. Although editions Schedules are available on KDE, Xfce and others, the GNOME version is the only officially called Ubuntu. In this version 11.04, it's still GNOME 2.32 which is present but not in its "usual". Indeed, the interface called Unity, and is built on a model that should allow the use future of Ubuntu on the shelves. 

In fact, the handling of Unity is quite different from the conventional GNOME interface. There is thus a Launcher in its operation recalls the Dock of Mac OS X. It is to the left of the screen and it displays both shortcuts there are active applications that place, marked by small arrows. Any opening a window causes the appearance of an icon, the only limit being final resolution of the screen. The Launcher appears when the mouse comes to left of the screen, or pressing the Windows key on the keyboard.

If the user has to click on the Ubuntu logo in the upper left the screen, it shows the Dash. This includes everything that is present in the system, including all applications and settings. It is also has a search box that displays results as and when the seizure, as the Windows Start menu for Vista. The Research also work for the documents.

Another new element, the management of workspaces. It is not exactly the function integrated to GNOME 3.0, but improved management virtual offices classic. The function looks uncannily Spaces in Mac OS X. we thus find a button to display the four offices coast to coast, which allows you to move applications, documents and more broadly windows from one to another easily. 

More news

More conventional, Ubuntu 11.04 arrives with its updates of applications, componentsand packages. Like a growing number of GNU / Linux, open source office suiteLibreOffice here in version 3.3.2, replaces Despite the recent changeof position at Oracle, there is no evidence yet to say whether OpenOffice will eventually return.

Also note the arrival of version 2.0 of the major audio / video player Banshee, and itsintegration into the sound menu, and Rhythmbox is no longer present.

Technical side, we find the following:
Linux kernel, which contains its own improvements, such as inclusion ofAppArmor, the support of the Intelligent Power Saving Intel's withdrawal from the BigKernel Lock, the latest driver updates and improvements to ext4 file systems, XFS andBtrfs and Mesa 1.10.1 7.10.1 for display
All major packages have been rebuilt and are installable via Python 2.7
Upstart 0.7.9-1
For the server version, improvements are noted, such as the presence of 2.0 PowerNapwho has a new method to reduce consumption by activity of the user, system andnetwork. The dhcpd server default password in addition to dhcpd3 isc dhcp-4, andEucalyptus is updated to version 2.0.2, which includes patches.

Other new editions are found in appendices of Ubuntu, including Kubuntu which usesKDE 4.6.2 now, as Xubuntu uses the Xfce version 4.8 was released in January. Thosewishing more information can visit the official announcement.

Tony Hawk Shred on Xbox 360

The original handling is rather attractive in the first games but the gameplay lacks depth on the final length. Not only is the list of tricks is very small, but the content itself is also a bit too light. Do not look for Campaign mode, it is simply a succession of levels with no real consistency. Five modes are fairly standard proposed by level: either to make the most tricks, or get points on your route, or else face many challenges ... The fact that you excel in these disciplines will allow you to win stars that will open the door to the next levels. In short, the whole remains very classic and unfortunately lacks madness
