Yet another column

I got the opportunity to write another column for this week. The topic is Spam,
it’s ten year anniversary, and why Microsoft’s ”Penny Black” system, where the sender
buys a virtual stamp by performing ten CPU-seconds worth of calculation, is a good
idea but not the end-all, be-all of spam prevention. I also give a modest proposal
on how to stop spam for good. It’s up here,
in swedish as usual, and will hopefully be up on the main
tomorrow, where people can comment on it. You can comment on it here instead,
for the time being. All two of you.
