This link kills spam

If you link to this page, whenever a harvester visits your site, it gets filled up with superfluous email addresses. These email addresses change every time this page is visited.

(A sample of the emails are shown below. These emails continue on below the screen, but you can't see them to save space)

Don't know if this works...will have to ask my son when he gets back from his meeting in Chicago


Email harvesting bots, otherwise known as data miners, follow links, grabbing email addresses out of each page it visits. When one of these bots comes to your site, all sites you've linked get crawled for email addresses.


This site renders these harvester's lists useless by filling them with invalid e-mail addresses. Once a spammer hits this site, they enter an infinite loop of randomly created email addresses (starting with the ones it generates when it first comes to the site) Once a mailing list has been poisoned with a number of invalid e-mail addresses, the resources required to send a message to this list increases, even though the number of valid recipients has not. This forces the spammer to exhaust more resources to send e-mail, in theory costing the spammer money and time. A best-case scenario would cause the spammer to throw out the mailing lists completely.

Dull jobs really do numb the mind

clipped from news.bbc.co.uk

Boring jobs turn our mind to autopilot, say scientists - and it means we can seriously mess up some simple tasks.


Monotonous duties switch our brain to "rest mode", whether we like it or not, the researchers report in Proceedings of National Academy of Sciences.


They found mistakes can be predicted up to 30 seconds before we make them, by patterns in our brain activity.


The team hopes to design an early-warning brain monitor for pilots and others in "critical situations".


The scientists say the device would be particularly suitable for monotonous jobs where focus is hard to maintain - such as passport and immigration control.


"To our surprise, up to 30 seconds before the mistake we could detect a distinct shift in activity,"
"We can assume that the tendency to economise task performance leads to an inappropriate reduction of effort, thus causing errors."

Brain reacts to fairness as it does to money and chocolate

clipped from www.physorg.com

The human brain responds to being treated fairly the same way it responds to winning money and eating chocolate, UCLA scientists report. Being treated fairly turns on the brain's reward circuitry.

"We may be hard-wired to treat fairness as a reward," said study co-author Matthew D. Lieberman, UCLA associate professor of psychology and a founder of social cognitive neuroscience.
"Fairness is activating the same part of the brain that responds to food in rats," she said. This is consistent with the notion that being treated fairly satisfies a basic need, she added.
"The brain's reward regions were more active when people were given a $5 offer out of $10 than when they received a $5 offer out of $23," Lieberman said. "We call this finding the 'sunny side of fairness' because it shows the rewarding experience of being treated fairly."
When people accepted the insulting offers, they tended to turn on a region of the prefrontal cortex that is associated with emotion regulation

Making the most of your RSS Reader from RWW

I really dig this short article from RRW. These are things I have thought about, like oversubscribing - is it good or bad? Should I use multiple readers or just stick to one. I have 2 accounts one on bloglines and one on google. But sometimes i feel so overwhelmed with all the subscriptions I have that I just sort of stop reading.
These are helpful tips and since next year we will be introducing RSS into the curriculum this might be some helpful pointers for students as well.

Seven Tips for Making the Most of Your RSS Reader

Picture 62.pngRSS is a big deal, as anyone who's subscribed to even a few feeds probably knows. Once you get past just a few feeds, though, it can quickly get overwhelming. RSS can leave you feeling inadequate, brain-dead and uninspired.

1. Oversubscribe

2. Try a River of News View

3. Use Multiple Services

4. Try Out a Desktop Reader

Five Things I Love About Firefox 3

Five things I love about Firefox 3

  • Because this is a beta version, most of my extensions and themes don’t work in F3…and I don’t miss ‘em. I’ve been using it all day and haven’t had a single withdrawal symptom.
  • Fast. Hella fast. Hecka fast. So damn fast. The memory management of Firefox 3 is slick. It caches less, stores image data more efficiently, and plugs memory leaks from extensions before they happen. This all comes from of the kind of nerdy nerdy attention to detail that was a feature of pre-Moore’s law programming, when bits were carefully placed like bricks in an arch. Hooray for OCD programming!
  • Oh Bookmarks! Ye annoy me less! You are now a one-click thing on the navigation bar, with a cute star icon instead of a time-eating top menu monster.
  • Full Page Zoom. If you don’t like squinting, download this browser. Hitting Ctrl + makes EVERYTHING get bigger, including images. This feature eliminates the “Big Text Stomps Nice Layout” problem we saw in earlier versions.
  • Tab quickmenu.
