You probably read about all this stuff with Facebook and sticking you in ads to your friends.  The place on Facebook to turn this off is shown below:

I heard about this from, I think, Rachel Clarke.  I promptly went to this page and set it to No one.  Imagine my surprise when I went back to this page, saw a pop up from Facebook telling me about the rumors surrounding this feature, etc, etc, and then seeing that, without my permission, they had reset this back to my friends.  I’ve again set it to No effin anybody.

Funny Daily Show video looking at the trouble Treasury Secretary Timothy Geithner is having selling his own house. Among other things, Geithner bought it at the peak of the bubble and now won’t drop the price enough to sell it. Gosh, good thing he isn’t giving advice to anyone on housing. Oh wait.

It seems as though IE is keeping all comet connections open even when I refresh or load to other pages. IE's connection limit is 2 per web domain. If I refresh the page twice, the third refresh sticks, because the comet connections from the previous page loads are still alive. I know it's my comet code doing this because when I comment my comet code out, the sticking doesn't happen. I think I finally figured it out, and I'm exhausted.

Another problem with shared web hosts is concurrency. Comet is much
different from typical HTTP requests in that it leaves connections open
indefinitely. Some shared web hosts will set Apache to limit you to as few
as 25 simultaneous client connections. I think Apache's default limit is
150.
scalability is another major hurdle. Assuming you're using Apache,
and if each thread consumes 3MB of memory, then 25 concurrent connections =
75MB of memory. Unlike typical HTTP requests that are very short-lived,
Comet connections can easily consume a lot of resources.
Regarding data sharing across HTTP requests: you may want to give PHP's
semaphores and shared memory a look, but it's only supported in Linux and
other System V operating systems. There's limited support for shared memory
in Windows, but only if you use PHP as a module and not via CLI or CGI.
