Managing Files At the moment I am training for computer science c children, and sometimes cook them to the 'competition'. With one 14-year old teenager, we did the project described below. The theory summarized the problem. Sysadmins have to work with large data: copy, archive, move, rename, etc. Likely to work, they use special tools or write a small 'applets' for yourself. For example, in Linux common spelling of bash-scripts. Gipotezaz. Python programming language is a good tool to perform the above tasks, and also has the happy advantage. Purpose. Explore the possibilities of the Python programming language and create a small program (a first module), which performs functions such as searching for files in the directory on the grounds of the name, size, time of change (create, open), but also allows further sort (copy, move, delete). Bibliography. Among other things, in many respects, we relied on the book 'Python in System Administration unix and Linux' (Gift, Jones). The general scheme of the program can be represented as follows: I understand that in fact is an attempt to reproduce the functionality of tools find. However, in the student projects are important to learn something, gain practical skills. 'Discovery' was credited with the fact that the utility has turned out more convenient and works great in Windows. When defending this work between a teenager and an assistant professor there was something like the following dialogue: - Lack of your work - is to use text-based interaction with users. - The program is designed for system administrators. Do I need a gui? Can the above program with a valid and practical significance? (Perhaps our assumption in the problem that is often required to sort the files not initially true).

Choosing the Right Laptop Now down to business - we will take to answer the question: Which processor should be a laptop? Response: Current processors today are the Intel Core 2 Duo or amd Turion 64 X2, they provide maximum performance and support the newest operating system Microsoft Windows Vista, notebook Acer TravelMate 6292 and Acer Travelmate 6292 laptop are the outstanding representatives of these processors. Middle ground between price and performance can boast Processor Intel Pentium M, for example, a processor used in the Tablet pc Acer TravelMate C310. If the performance of the notebook is important to you is less than the price of a laptop, in this case, laptops with Intel Celeron M processor is exactly what you need, an example can serve as a notebook Acer Extensa 5200 and Acer Extensa 7220. Go to Atmos Energy for more information. The second important issue when choosing a laptop is the ram on your laptop. 512 mb ddr will be enough for comfortable work on the Internet, Word, Excel, for viewing movies, and also for undemanding games. It is worth noting that the notebook company Acer, the ram can even add your own. The ideal amount of ram in a laptop is 1024 mb, and for working with demanding of system resources applications for at least 2 gb of ram, most Acer notebooks support the expansion to 4 gb. It is necessary to pay attention to the following question - laptop with a graphics card to buy for graphics? There are three types of Video - is integrated into the chipset, memory, which is taken from memory, discrete - the best and most hybrid cards. Built-in chipset graphics certainly weak for heavy graphics and games, but the price of Such laptops are considerably lower than with a discrete graphics card. An example...
