+ - How much sleep do you need?

Submitted by

phorm writes "I was recently having a discussion with a friend wherein we noticed that, although we had been lacking in sleep lately, we were — in general — feeling somewhat less tired. More specifically for myself, I generally end up feeling more alert in the morning, sometimes with a more steep drop-off towards night.

This had led to research over the concept of how much sleep is optimal, and how much is enough. Interestingly, it seems that many who are into heavy fitness schedules (bodybuilders etc) require lesser sleep amounts to maintain an alert state. This would seem to fit with my own observations, in that if I have exercised heavily, I tend to fall into a deeper sleep, within a shorted period of time. However, if I have exercised in a way that has over-strained my body, sometimes extra rest can be required, most likely so that it can "fix" itself.

I have many memories of college wherein intellectual stimulation would also have the same result. Coding would run into the early AM hours, and at some point when my brain was reduced to gelatin I would return home for about 3-6 hours of sleep, and still manage to feel active and refreshed the next day. Coding where I went to bed before my brain gelified might result in tossing-and-turning.

Stimulants, of course, affect either of these situations, but as I'm not much of a caffeine drinker (particularly later in the day), I believe that can be ruled out.

So, how much sleep does a normal slashdotter need before being able to achieve uncaffeinated alertness? What tips and tricks can you recommend to pull a few extra hours out of the day (much like many fitness fanatics do) without sacrificing your health or alertness? How do you trick your body into achieving the almighty "power-nap" or "super-sleep" for quick revitalization?"

In an unanimous decision released today, Helsinki District Court ruled that Content Scrambling System (CSS) used in DVD movies is "ineffective". The decision is the first in Europe to interpret new copyright law amendments that ban the circumvention of "effective technological measures". The legislation is based on EU Copyright Directive from 2001. According to both Finnish copyright law and the underlying directive, only such protection measure is effective, "which achieves the protection objective." ..."

This is a follow-up to earlier /. story that Vendor [Diebold] contends state erred in selecting AutoMark voting machines of rival. From TFA: "The suit is still there, but they went zero for three yesterday," the spokesman said. No further hearings have been scheduled yet, he said. The actual accessibility concerns have been discussed over at the TEITAC ListServ, including a few telling observations from experts familar with accessible voting and at least one state insider."

eldavojohn writes "Space.com is covering NASA's commemoration of the Apollo 1 crew & the last shuttle crews of both the Challenger and Columbia orbiters. The Apollo 1 crew was lost forty years ago today to a fire while testing their spacecraft on a launch pad. From the article, "While the nearly two decades separating NASA's three space disasters allowed room for the agency to grow complacent, the relatively short time between the 2003 loss of Columbia and the end of the shuttle program could avoid a repeat of such behavior.""

+ - Inside the Lucasfilm datacenter

passthecrackpipe writes "Where can you find a (rhetorical) 11.38 petabits per second bandwidth? It appears to be inside the Lucasfilm Datacenter. At least, that is the headline figure mentioned in this report on a tour of the datacenter. The story is a bit light on the down-and-dirty details, but mentions a 10 gig ethernet backbone (adding up the bandwidth of a load of network connections seems to be how they derived the 11.38 petabits p/s figure. In that case, I have a 45 gig network at home.) Power utilisation is a key differentiator when buying hardware, a "legacy" cycle of a couple of months, and 300TB of storage in a 10.000 square foot datacenter. To me, the story comes across as somewhat hyped up — "look at us, we have a large datacenter" kind of thing, "look how cool we are". Over the last couple of years, I have been in many datacenters, for banks, pharma and large enterprise to name a few, that have somewhat larger and more complex setups.

It used to be so that the the SFX industry had the largest, coolest, hottest technology around. Is this still the case?"
