How Legal Wire tapping Works
CALEA requires that communications providers allow law enforcement officials to be able to listen in on phone conversations and get information about those phone calls, but only when the law enforcement agency has gotten approval for the tap.

Throughout the history of the United States, one of the greatest political tensions has been that which balances personal privacy against the need for law enforcement to protect individuals and the country as a whole.
That tension has been with us from the very earliest days of the Republic. The Founding Fathers were extremely cognizant of […]
How do we know if we have any rows in a table? We use the COUNT function to return a count of the number of rows in a table. If you enter Listing into Query Analyzer we can check the data insert for the Spy table.
This will return the current number of rows (well actually […]

If you are using Windows 2000 Advanced Server or Windows Server 2003 Enterprise or Datacenter servers, you can use the clustering feature for DHCP. This allows two separate DHCP servers to be administered as a single DHCP server. Windows 2000/2003 clustering supports a failover mode in which a service running on one computer can be […]
Many small- to medium-sized networks use the router that provides Internet access as a DHCP server, using it to provide network addresses to client PCs.

Okay, it’s time to illustrate how the AD installation process works under Windows Server 2003. The example here is based on the Enterprise edition, but the process is similar for all other Windows Server 2003 variants (except for the web edition).

HTTP Mechanics

Just as in a large corporate network, you might have a problem with one or more components that make up the network. Network cards go bad, as do hubs and switches (and even individual ports on a hub or switch). Always keep handy the minimal documentation that comes with your computer(s), network card, hub, switch, […]
A pattern-matching IDS can look at a sequence of events to detect a problem. For example, if someone is suddenly removing dozens or hundreds of files, you might be faced with a disgruntled employee about to leave a system in an irreparable state.

Smith and Chaffey (2005) use the acronym CRABS to summarize effective web-page copy. This is even more appropriate to e-mail copy, since we typically have even less space to communicate. CRABS stands for:
Chunking. Chunking means that paragraphs must be shorter than in paper copy — think one or two sentences, three or four maximum.
Related to the five targeting approaches above, it is also useful to consider using design personas for typical customer types. This is a powerful web-design technique used to improve the usability and customer-centricity of a web site. It has the benefit that it characterizes segment types in the context of the targeting options mentioned above, […]
