Reverse Ajax

Reverse Ajax, not unlike DHTML, LAMP, Ajax and SPA, is not a technology in itself, but a term that refers to the use of a group of technologies together. These technologies include:

  • Ajax for handling the data on the client side in a smooth and interactive way, and passing data between server and client.
  • A technology for pushing server data to a browser
    • Comet, a connection between a server and client is kept open, by slowly loading a page in a hidden frame.
    • Piggyback, extra data is added (piggybacked) onto a normal client-server interaction.
    • Polling, the client repetitively queries (poll) the server.

Reverse Ajax is different from Ajax, as Reverse Ajax is a suite of technologies for pushing data from a server to a client. These technologies are built upon an Ajax framework.

Drupal modules and themes

Drupal core is designed to be modular with a system of "hooks" and "callbacks", which are accessed internally via an API.[1] This design allows third-party contributed (often abbreviated to "contrib") modules and themes to extend or override Drupal's default behaviors without changing Drupal core's code.

Domain hack

A domain hack is an unconventional domain name that combines domain labels, especially the top-level domain (TLD), to spell out the full "name" or title of the domain, making a kind of pun.

For example the second-level domain (SLD) blo.gs makes use of the TLD .gs (South Georgia and the South Sandwich Islands) to spell "blogs". The third-level domains del.icio.us and cr.yp.to make use of the SLDs icio.us and yp.to from the TLDs .us (United States) and .to (Tonga) to spell "delicious" and "crypto" respectively.

In this context, the "hack" represents a clever trick (as in programming), not an exploit or break-in (as in security).

Googlefight Keep vs Delete

Here are some ways to use Google, Alexa, Yahoo! and Clusty to check articles and other information.

Types of Google tests

On Wikipedia, a Google Test is any use of Google or other search engines as references. Several very distinct kinds of information can be gleaned by this method. It should be stressed that none of these applications is conclusive evidence, but simply a first-pass heuristic or rule of thumb.

Google "First Click Free" for protected areas

Google found a solution to index the web pages protected by webmasters or owners. "First Click Free" means to allow Google to include your protected pages in the search results, and to provide full access for the text on that page. This way, the first visit is free for paid subscription and other protected pages and does not require a login. The free visitor can be block for the other protected pages or sections.

Spam

Spam messages

Spamming is commonly defined as the sending of unsolicited bulk e-mail - that is, email that was not asked for (unsolicited) by multiple recipients (bulk). A further common definiton of spam restricts it to unsolicited commercial e-mail, a definiton that does not consider non-commercial solicitations such as political or religious pitches, even if unsolicited, as spam.
