This includes tags such as BASEFONT and CENTER, which have been deprecated; tags such as COMMENT and MARQUEE, which are exclusive to Internet Explorer; tags such as SPACER and SERVER, which are exclusive to Netscape Navigator; and even tags such as !DOCTYPE and BASE, which are included merely for the sake of completeness.

Recently, every website on our primary server was simultaneously attacked. The offending party indiscriminately replaced the contents of every index file, regardless of its extension or location, with a few vulgar lines of code, which indicated intention, identity, and influence. Apparently, the attack occurred via Germany, through a server at the University of Hamburg (uni-hamburg.de). This relatively minor attack resulted in several hours of valuable online education. In this article, it is our intention to share experience with website attack […] Continue reading »

About the Robots Exclusion Standard: The robots exclusion standard or robots.txt protocol is a convention to prevent cooperating web spiders and other web robots from accessing all or part of a website. The information specifying the parts that should not be accessed is specified in a file called robots.txt in the top-level directory of the website.

I love looking at beautiful source-code output. However WordPress tends to spit code out in random chunks, often leaving spaces, line breaks, and tabs littered throughout the source output. This messes things up. Lists don’t look like lists and logically written code often appears scattered along the page carelessly. Often, this is the result of poorly written PHP, which can be manipulated to write beautifully aligned code that looks as good as it works. Continue reading »
