    An optical illusion worth playing with
In this image. The squares marked A and B do indeed have the same RBG values. My trusty Paintshop Pro reports RGB = (107,107,107).
A good way to see that you are not crazy is to cut away bits of the image bit by bit until you are just left with a vertical band running from A to B. As you strip stuff away, you will see that your brain registers B as darker and darker. By the time all remenants of the gray square south of A and North of B is gone, B will have faded (untouched!) in your brain to the same shade as A. Amazing.

    Proposed SPAM legislation in Ireland
The Fine Gael party has a proposal on SPAM. Its great to see legislators taking this probem seriously but forcing the intermediaries like the ISPs to filter it is *not* the way to do it.
Lawrence Lessig's ideas on this subject deserve close examination in my opinion.
On a geek note, I'm worried that putting such smarts into the arteries of the internet are deeply at odds with the edge principle so beautifully illustrated to date by the Internet.

    More link knowledge for blogs?
Lots of blogs have web-traffic monitors such as those provided by stats.blogger.com.
These stats are normally private to the blog owner.
What if users made their stats public the same way they make their RSS public?
Wouldn't the information therein add an extra dimension to blog searching?
Let me see, each item would be a link into the blog with a date and a description being the referer that got you there.
A collection of items that have dates, titles and descriptions...where have I come across that before?
