Re bike tires, I haven't had a flat for quite some time with Schwalbe Marathon (http://www.schwalbetires.com/) tires, shards are no problem, thorns or nails might puncture them in some cases.
The number of zombied machines that are reliable (online 24/7, static ip, good bandwidth) is probably rather small as opposed to machines with DSL or cable.
If those machines are dDOSed their zombie problem will get fixed in a hurry (because the ISP/owner won't want to pay for the traffic, which they will have to notice because the line is going to be completely saturated). I fail to see that as a bad thing.
This may indeed be true most of the time, but as an admin in a students dorm with strict traffic limits I have firsthand experience with Skype users causing a lot of traffic, presumably because they are acting as a relay. They usually don't know about this "feature", of course.
This is an omission in the writeup, according to Ananova "filters will cost about as much as a cigarette". The battery, heating element etc. are reused.
MD5 is limited to 2^128 possibilities (which is bigger than the number of atoms in the universe)
It isn't. Not even close.
To put it in chemical terms:
2^128 / 6*10^23 ~= 5.67 * 10^14
6*10^23 is about one mole, approximately the number of molecules in two grams of hydrogen (H2). So, 2^128 molecules of H2 weigh about 567 million metric tons. Sounds like a lot, but our sun weighs about 10^18 times that (and since the sun weighs 333 times as much as the earth, even the earth consists of far more than 2^128 atoms).
Hope this cleared that up.;)
That said, there are stipulations that our sun can't produce enough energy to allow a brute-force search of a 128 bit keyspace without quantum computers, which sounds reasonable.
True, but IE 6 grows at the expense of the other IE versions. If you look closely (have a magnifier handy;) you will find that Mozilla (the pinkish line) has been rising steadily in the last year.
Why don't you just use arpwatch? That's a daemon to keep track of all MAC<->IP pairings, it sends an email if something changes. Plus, those hosts don't have to connect to your machine for you to detect them.
You can then use procmail or your version of biff to play sounds.
Machines make too many mistakes, so let's use...wait for it....HUMANS.
It's not about mistakes. Those are easily minimized. Just make sure there are always two people looking at ballots and sorting them etc. It's about tampering. Tampering is just ridiculously easy with the current machines and the lack of process.
I wonder when there will be a big fat pipe going from western europe to east asia that does not depend on the USA.
There is a direct link, although it's not all that fat. It's called FLAG (fiberoptic link around the globe). Search google. The first hit is an article by Neal Stephenson, a great read.
For discussion style mail lists you can use ezmlm. But if it's just one way, one to many broadcast, just qmail will do.
I definitely second the choice of qmail + ezmlm[-idx]. (-idx for the moderation features);)
But for a list of any size you probably want the software to handle subscriptions and bounces automatically and securely, and ezmlm does just that by sending cryptographically secure confirmation requests and handling bounces by encoding the subscribers address in the Return-Path.

Compact fluorescents really have become quite good, the only drawback is the higher initial investment, but they help save a lot of money over time.

There's a little problem here: Most European pager operators went bankrupt about 5 years ago, there are countries without pager coverage.
Thanks, that makes a lot more sense (damn those ambiguous number separators). Good thing I had a few orders of magnitude to spare. ;-)

That's what ulimits are for (max user processes). Those have been in UNIX for at least 20 years, Linux must have gotten them in '92 or so.

See last month's Crypto-Gram for an account of the stakes.
Gambling on Voting (NY Times Op-Ed today)
I don't understand this run on machines anyway, don't paper ballots scale perfectly? Counting votes can be arbitrarily parallelized after all.
