Submission + - The Equationater (equationater.com)

JohnGrahamCumming writes: "I had an itch that needed scratching... I needed to render equations on the web and I didn't want to rely on something like MathML because of poor browser coverage. So, I created The Equationater. Type in an equation in LaTeX format and it is instantly turned into a PNG file that you can download or link to."

Submission + - Cryptographically hiding TCP ports (sf.net)

Submitted by

JohnGrahamCumming writes: "The shimmer project implements a cryptographically-based system for hiding important (e.g. SSH) open ports in plain sight. By automatically forwarding from a range of ports all but one of which are honeypots and by changing the ports every minute only a user knowing a shared secret can determine the location of the real SSH server."

Submission + - 'Wildfire' brings social news to Facebook

Submitted by
JohnGrahamCumming
JohnGrahamCumming writes: "My newly released Wildfire application brings social news to Facebook by exploiting Facebook's social graph. Instead of "digging" stories, or "voting up/down", stories gain credibility only if you deem them worthy of being passed onto your friends. Wildfire offers users three views of the news: the news you and your friends deem interesting, the news that the great unwashed deem interesting and a random view. Randomness means that the Wisdom of Crowds is harnessed without succumbing to mob rule. And RSS integration means you can automatically bring your feeds to Facebook and pass on a subset of the stories. Personally, I started with the Slashdot feed."
It's funny. Laugh.

JohnGrahamCumming writes: "1,225 Facebook applications. 73,109,074 installed in profiles. Hence, the average application has 59,700 users. The problem with the average is that it hides a savage reality of Facebook applications: some have many users, most have almost none. 86% of applications on Facebook have less than 10,000 users, with 62% having less than 1,000."

RFID, Sign of the (End) Times? 843

Posted by ScuttleMonkey from the sky-is-falling dept.
andy753421 writes "Wired is running an article featuring Katherine Albrecht who, with her new book 'The Spychips Threat: Why Christians Should Resist RFID and Electronic Surveillance', is warning that RFID tags may in fact be the "mark of the beast". Among her arguments are that in a futuristic world anyone who wishes to buy and sell goods would be compelled "to receive a mark on their right hand or on their foreheads," as is foretold in the book Revelation. Others are skeptical saying that many new technologies, such as the printing press, bar-codes, and several others, have also created fears about the beginning of the end."
