Language: Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. In its simplest form, a Sitemap is an XML file that lists URLs for a site along with additional metadata about each URL (when it was last updated, how often it usually changes, and how important it is, relative to other URLs in the site) so that search engines can more intelligently crawl the site. Web crawlers usually discover pages from links within the site and from other sites. Sitemaps supplement this data to allow crawlers that support Sitemaps to pick up all URLs in the Sitemap and learn about those URLs using the associated metadata. Using the Sitemap protocol does not guarantee that web pages are included in search engines, but provides hints for web crawlers to do a better job of crawling your site.
Ping: ICMP vs. ARPNetwork and system administrators are well-versed in using the ping utility for troubleshooting purposes, but where do you turn when ping doesn't do the trick? Pinging a host is usually the first step in determining if the host is properly connected to the network. If the host does not respond to a ping request, the host is usually assumed to be offline.MeBroad pronouncement of the week: We are entitled brats. For immediate proof, turn on the television. Locate a reality show on Bravo or MTV.Common Errors in EnglishGo to list of errors. What is an error in English? The concept of language errors is a fuzzy one. I’ll leave to linguists the technical definitions. Here we’re concerned only with deviations from the standard use of English as judged by sophisticated users such as professional writers, editors, teachers, and literate executives and personnel officers. The aim of this site is to help you avoid low grades, lost employment opportunities, lost business, and titters of amusement at the way you write or speak.
Lagrange multipliersFigure 1: Find x and y to maximize f(x, y) subject to a constraint (shown in red) g(x, y) = c. Figure 2: Contour map of Figure 1. The red line shows the constraint g(x, y) = c.Download Free Windows 2000 Resource Kit Toolsby Daniel Petri - January 8, 2009 Where can I download the Windows 2000 Resource Kit tools?

Linux Commands for Beginning Server Administrators - www.reallylinux.comAllows you to change the timestamp on a file. Most common use: touch filename Using the basic touch command, as above, will simply force the current date and time upon the specified file.Online base64 encoding - base64 decode and encodeThis online sample demonstrates functionality of a base64 property, ByteArray class and Huge asp file upload. You can convert texts using several code pages (using CharSet property) from Unicode string to byte array and then convert the binary data to a Base64 string. The sample uses a special Base64 algorithm written for the ByteArray class. The Base64 conversion algorithm is written in C++ and works with binary (VT_ARRAY | VT_UI1) and String (BSTR) OLE data. It contains hi-speed and low-memory consumption BSTR->BSTR, BSTR->BINARY, BINARY->BSTR and BSTR->BSTR algorithms.
Sharing files with wdfs and FUSEKeeping one set of files means never worrying about synchronization and merging. Changes never get unknowingly overwritten, and I have a single, simple backup strategy. WebDAV is the Distributed Authoring and Versioning extension to HTTP. On Apache systems it is usually implemented with mod_dav, and many Web hosting companies provide it as an option, giving you a simple "flip a switch" path to run your own WebDAV server. WebDAV can run over HTTPS, providing a layer of security, and it requires setting up its own username/password combo for each user -- distinct from any other server accounts or .htaccess -- so you can even set up different WebDAV accounts for each machine you use and meticulously track changes. But I'll skip explaining the WebDAV server setup; first of all, plenty of excellent information is out there already, and second, the beauty of wdfs is that the FUSE module abstracts the details away.
