Phoenix carries Linux to the north pole of Mars

Phoenixlander landed at the north pole of Mars in May 26 this year, and then found ice cubes with water. This is an amazing discovery. Phoenix is said to be an immortal Bird, indicating good fortune. This landing was successful, and it was a good experience (probably the blessing of Phoenix birds ).
According to relevant reports, the core software of the Phoenix lander control system is a variant of the Linux operating system (variant) called "VxWorks ". VxWorks Program Code Embedded on a chip similar to a USB flash disk, You can reactivate it if necessary. Phoenix's hardware configuration is not high. The CPU (a simplified Instruction Set Processor), 33 MHz clock speed (equivalent to intel386 processor), and 128 MB memory. Phoenix processor and motherboard are both made by IBM. Phoenix received instructions from the earth, with a latency of 20 minutes. Therefore, it has strict software requirements and must be able to "self-protect" or even "self-correct ". On the earth, 1000 to 1500 commands are sent to it every day. If something goes wrong, it will be very troublesome. The aerospace industry is not a joke. Today, all of us on this planet are proud to claim that, on another very distant planet, the Linux operating system is constantly running on Phoenix. Cool is really exciting ).
Solid State disks (SSD, for example, self-starting USB flash drives) are the future development trend. In the face of this trend, people must adapt (this is a matter of time ). Based on the title of this article, what is the explanation of "Ubuntu comes to Beijing? At noon the day before yesterday, I went to Beijing book building and found a treasure book named "ubuntu standard tutorial ". The reason why the book is called a treasure book is that there is no trace of Linux on the cover of the book, calling "ubuntu Operating System" directly ". This is because, in today's time, the so-called "Operating System" should be a software system that can process text, images and multimedia "broad electronic documents. Ubuntu software package, of course, is called an "Operating System". It is different from pure Windows XP and Vista, which already contains various processing methods for text, images, and multimedia, users no longer need to look around, so that unauthorized software is misused. It is referred to as a "pirate ". For example, the Ubuntu operating system contains a complete set of processing tools for text, images, and multimedia, which can be imported, exported, browsed, and even managed from mobile storage and digital cameras; capture images from the screen, as well as the application tools and software for recording CD/DVD discs. The advantage of the Ubuntu operating system is that it integrates all the software tools required by general users, so that users do not have to worry about piracy and infringement, so they can go wherever they go. Especially in public places, you can play with your own private house software without fear of criticism: "Let's see, someone is playing with pirated software !", That's a matter of shame. Today, Ubuntu has come to Beijing, the increasingly civilized world. It is a pleasure.
