The makings of Skynet?


The video is about a scientist who took some rat brain tissue, broke it down into neuron level components, and provided input from a flight simulator to and from the resulting goo. The neurons were able to start self organizing and learn to fly a computer flight simulation.

Very cool experiment, and the whole time I'm thinking "Where's the Terminator?"

You just got pwned.

Mornings, a time for reflection, quiet, contemplation. Not. I have 3 kids, mornings are a time for energy, excitement, and the occasional (ok, often) wise crack. This morning I'm making my breakfast and my wife is explaining how she slept better after getting the humidifier going last night.

Wife: "... and I didn't wake up as ..."

My 4 year old, without missing a beat, interjects: "Emotional?"

I was glad I wasn't drinking anything. I would have sprayed it all over the kitchen as the laughter struck me. Point awarded to the 4 year old!

A tribute to John Williams...

Now that's my kind of rule....






Now that's someone who's thinking. The whole set of images can be found here. It's a series of images from Zoo's worldwide.

Which one wins?

One evening an old Cherokee told his grandson about a battle that goes on inside all people.

He said, 'My son, the battle is between two 'wolves' inside us all. One is Evil. It is anger, envy, jealousy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego.

'The other is Good. It is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion and faith.'

The grandson thought about it for a minute and then asked his grandfather: 'Which wolf wins?'

The old Cherokee simply replied, 'The one you feed.'

Quirk with Postfix and Dovecot...?

Over the weekend I got pulled into a tech call where my "CEOs Email wasn't working". To setup things here, we're on CentOs 4.latest with Postfix 2.2.10 and Dovecot 0.99. All patches are applied and up to date.

Sure enough there were a few pop3 processes sucking down 100% CPU loads. The log showed:
Nov 2 12:39:57 mail pop3(ceo@domain.com): Timeout while waiting for release of shared fcntl() lock for index file /var/spool/mail-domains/domain.com/CEO/mail/.imap/INBOX/.imap.index
A quick look showed that there were multiple processes locking out the file. After some "duhs" I got the right processes stopped, killed the remaining, and restarted. No change. Restarting all processes involved also showed no change. The moment the user came in, things locked back up. Tried removing and rebuilding the IMAP files, no change.

Eventually, I came around to the old standby and I did a $ mail -f CEO/mailbox and then quit out. That fixed it. Still not sure why.
