Book Description
Just about every C programmer I respect learned C from this book. Unlike many of the 1,000 page doorstops stuffed with CD-ROMs that have become popular, this volume is concise and powerful (if somewhat dangerous) - like C itself. And it was written by Kernighan himself. Need we say more?
This book presents a complete guide to ANSI standard C language programming. Written by the developers of C, this new version helps readers keep up with the finalized ANSI standard for C while showing how to take advantage of C's rich set of operators, economy of expression, improved control flow, and data structures.
This 2nd edition has been completely rewritten with additional examples and problem sets to clarify the implementation of difficult language constructs.

Copying Online Messages

When posting messages online, it’s a good idea to copy the message to your clipboard before pressing the Send button. Ctrl+A, then Ctrl+C.

If the Send doesn’t take, you can just paste your clipboard contents back again in a new post window.
If it appears to have been sent, but it’s important, you can paste it into a Notepad .txt file (Ctrl+V) .
If the message disappears into digital limbo or if the recipient at the tax department denies receiving it, you at least have a copy of the original to resend.
If it’s a long tome, copy it at several intervals.

Computer Buying Tips

Should You Buy a Mac or a PC?

 

Deciding whether to buy a Mac or a PC should be based on two main points: your budget and whether the computer is primarily for business or pleasure. Both types of computers are excellent for specific tasks, although if you are planning to go to work and bring your computer with you, you may need to consider what types of computers your coworkers will have to make it easier to swap files or compare notes. Here a few basic tips on how to choose the right computer for you.

Budget

There’s no debate—Macs are far more expensive than PCs. If money is a big issue for you, you’ll want to buy a PC. However, Macs aren’t overpriced. Unlike PCs, each computer is designed for maximum efficiency in both processing speed and ease of use. While PCs frequently crash and are vulnerable to spyware and viruses, Macs resist most viral attacks and operate at a consistently high standard with virtually no technical issues. If you can afford it, a Mac is an excellent investment which will work for you for years.

Business

While Macs have always been the preferred computer of graphic designers and other creative individuals, for most corporate office work, PCs have long been favored over Macs. For this reason, PCs still dominate in most business settings.
Up until a few years ago, the major software designed for business suites, like the Microsoft Suite, was designed chiefly for PCs. However, the popularity of other Apple products such as the iPod and iPad has started to change the way Macs are perceived in the larger corporate world. Most business software now has versions available for both Macs and PCs. Because of their heftier price tag, Macs still have a long way to go in making a dent in the corporate world, although in terms of functionality they perform just as well as a PC.
Graphically, Macs have richer displays and a Linux based operating system that makes them ideal for manipulating complex information such as layered graphical displays. Photoshop was initially designed for the Mac. If you are buying a computer for use in a professionally creative setting, your coworkers will likely also be using Macs.

Programming

Computer programmers are evenly split on whether Macs or PCs make better programming tools. The truth is, it comes down to a matter of personal preference. Macs developed a comprehensive suite of developer tools with their OS 10 which, if used properly, can help you get to the moon. PCs have always been oriented toward programming; in fact, the DOS/Windows interface was developed mainly as a way to stay competitive with the user friendly Mac interface. However, many programmers have complained that Macs are slower than PCs when it comes down to executing large amounts of freshly programmed code.

Personal Use

If you enjoy playing video games in your spare time, buying a PC is probably the best choice. This is partly because PCs are easier to hook up to auxiliary equipment like television sets or other devices. Although USB ports are evenly distributed between Macs and PC, the higher data transfer portals of a Mac do not always adapt easily to most conventional televisions, making it difficult to quickly relay information between the two devices, whereas the higher data transfer portals of a PC are usually very adaptable to auxiliary devices.
If, on the other hand, you prefer to design or develop creative projects in your personal time, Macs are a much better choice. Because Apple has invested so much time in making the user interface incredibly easy to use, spending time creating music or drawing or editing movies becomes less about the computer and more about the activity; you forget you are using a computer, and can instead focus on the act of creation. PCs have a more rigid approach; it’s hard to forget that you’re on a computer.

Cloud Computing and the Future of Virtualization

Of course, with the tech community excited about the potential of cloud computing, computer memory is going to become less of an issue, with flexibility, mobility, and processing speed becoming increasingly important when making purchasing decisions. Mac’s suite of mobile devices are far better adapted to shifting between different geographical areas while also offering enough functionality to make them viable business tools. However, for now you should buy the computer that best suits your needs, and plan on the inevitable: no matter what you buy now, in a few years it will be completely outdated anyway!
