Borland Delphi is known to be a great environment for the development of stand-alone and client-server applications on the Microsoft Windows platform. Its virtues range from full OOP support to visual development, in a unique combination of power and ease. However, the new frontier of development is now Internet programming. What has Delphi got to offer in this new context? Which are the features you can rely upon to build great Internet applications with Delphi? That’s what this paper intends to reveal. We’ll see that Delphi can be used:
• For direct socket and TCP/IP programming;
• In conjunction with third-party components that implement the most common Internet protocols, on the client or the server side;
• To produce HTML pages on the server side, with the WebBroker and Internet Express architectures;
• As well as to work with Microsoft’s core technologies, including MTS, COM, ASP, and ActiveX.

Once upon a time, the Internet was a wholly virtual environment, moored only loosely to the physical world. It was where information went to become free, where censorship was routed around, where communities could leap barriers of distance and culture in a single bound . . . and where no one knew you were a dog. The kicker was that these aspects were built into the fabric of the Net, thanks to its origins in military communications research. You couldn’t tie the Net to the real world if you wanted to.

Setting Options, and customizing the Drawing toolbar.
Under Tools, Options (Alt-t o), set the following:
“View” tab: Print and Web Layout Options—check Drawings and Object Anchors
“General” tab: If you are using Office XP, UNcheck “Automatically create Drawing Canvas when inserting AutoShapes”
(The Drawing Canvas is a new feature in Word 2002, designed to make it easy to create a complex shape. I have yet to discover any value to it, and find it to be simply a nuisance.)
“Edit” tab: Check “Enable click and type”. This may be useful when you are working with a drawing, since it allows you to position text in relation to the drawing without hitting the Enter key repeatedly.
If you are using Word 2002, I recommend unchecking “Show Paste Option Buttons”. These buttons get in the way, and even sneak there way into my web documents!

O*NET, the Occupational Information Network, is replacing the Dictionary of Occupational Titles (DOT) as a source of occupational information. O*NET is a database—not a book, like the DOT. This database has the qualities of both an interactive library and a language.
Serving as a library for information on the working world, O*NET allows everyone to access data on job characteristics and worker attributes. It includes information on the knowledge, skills, abilities, interests, preparation, contexts, and tasks associated with 1,122 O*NET occupations.

Although traditional firewalls have effectively prevented network-level attacks, most future attacks will be at the application level, where current security mechanisms are woefully inadequate. Application-level security vulnerabilities are inherent in a Web application’s code, regardless of the technology in which the application is implemented or the security of the Web server and backend database on which it is built. A recent advisory published by Internet Security Systems (see the “Internet Resources” sidebar, p. 44) claims that 11 widely deployed shopping cart applications are vulnerable to a simple attack that lets hackers pur- chase goods for much less than their listed price. Worryingly, the attack does not require particular technical skill; it suffices to save the shopping cart’s HTML confirmation form to disk, use a text editor to modify the price of the goods (stored in a hidden form field), and load the HTML form back into the browser.

With Windows Vista, Microsoft shifted from the development path of Windows XP wide open to tampering with zero reaction, and has integrated an anti-piracy infrastructure into the platform. In direct correlation with the Windows Genuine Advantage and the Activation mechanisms, Windows Vista will be able to detect and blacklist non-genuine product keys, crack attempts, and identify the expiration of the initial 30-day grace period. The operating system will react to all by moving first into a non-genuine state and then into Reduced Functionality Mode.

A new model joins the Accent lineup this year the Accent 5 a four door GL with a hatchback instead of a traditional trunk. This front wheel drive subcompact is powered by a 4 cylinder 1 6 litre engine that comes with either manual or automatic transmission. Interior and trunk Because the car is low to the ground tall people will find it somewhat difficult to get into. Once seated they will find the front seats quite comfortable especially the driver s seat with its two adjustment wheels that make it easy to find just the right driving position. Getting out of the rear seat is harder than getting into it foot room is limited and the doors open on a tight angle Since headroom is limited it seats two adults comfortably only if they are of no more than medium height.
