About LED Lighting
This is a pretty good article explaining LED lighting and the science behind it…
It seems like they’re already everywhere – if you look down at your keyboard, one is providing the little green indicator for your Num Lock key, while another may be frantically blinking to inform you of your waiting voice mail. On your next drive, chances are you will stop at a stoplight lit purely by LED’s and perhaps may notice a blinker made up of small, bright lights instead of one bulb. LED’s certainly are everywhere, faithfully providing indications of all kinds. But, with a few exceptions, the primary purpose of an LED is to indicate rather than illuminate, despite the fact that LED’s do nothing useful besides produce light. A few new developments, however, may bring solid-state lighting into our homes very soon.

Sleeping late?
I’ve always been a night-owl…
1 // You may need more sleep than you think.
Research by Henry Ford Hospital Sleep Disorders Center found that people who slept eight hours and then claimed they were “well rested” actually performed better and were more alert if they slept another two hours. That figures. Until the invention of the lightbulb (damn you, Edison!), the average person slumbered 10 hours a night.2 // Night owls are more creative.
Artists, writers, and coders typically fire on all cylinders by crashing near dawn and awakening at the crack of noon. In one study, “evening people” almost universally slam-dunked a standardized creativity test. Their early-bird brethren struggled for passing scores.3 // Rising early is stressful.
The stress hormone cortisol peaks in your blood around 7 am. So if you get up then, you may experience tension. Grab some extra Zs! You’ll wake up feeling less like Bert, more like Ernie.

A few years back I met Dave (you know, friend of my other friend Dave) just by chance as he flew thru’ the lobby of the building I was standing in (ya, with Dave)… and I we hadn’t communicated much since then… until that Facebook got a hold of us…
If you don’t know who Dave is, here’s a classic clip of him… (no not that Dave, the first Dave). 😉

Top Gear Reviews The Tesla Roadster
I think the best part is when he says that you should get two – one to drive, and one to charge… so much for the 200mile range (which was lowered from 250 already)
Is Apple *really* Green?
Apparently Dell is a little peaved that Apple is claiming to be green…
Several Dell folks were surprised and perplexed to see Apple’s new “green” MacBook ad since its release last month and we’ve been watching the discussions in the blogosphere. After chatting with our environmental teams about the topic, we realized that instead of ignoring it, we should have a conversation about the real meaning of being green from the viewpoint of a Fortune 500 company

The Latest on Caloric Restriction
I’ve written about Caloric Restriction in my blog here before a few times… and the more I read and learn about it the more interesting it is… the basic thought is “To live longer, eat less.” Read more in the article below:
In a laboratory at the Wisconsin National Primate Research Center, Matthias is learning about time’s caprice the hard way. At 28, getting on for a rhesus monkey, Matthias is losing his hair, lugging a paunch and getting a face full of wrinkles.
Yet in the cage next to his, gleefully hooting at strangers, one of Matthias’s lab mates, Rudy, is the picture of monkey vitality, although he is slightly older. Thin and feisty, Rudy stops grooming his smooth coat just long enough to pirouette toward a proffered piece of fruit.

Surface Mount Soldering 101
It seems that more of my projects need some soldering done as of late… and of course, more of that soldering is leading me to surface mount work. Although my soldering skills are pretty good, the surface mount work is a bit of a challenge. Here’s a video I found that makes it look “oh so easy”. 🙂
Wireless Keyboards = BAD
This was inevitable, but only 256 keys? cummon!
if you sniff the handshake, you can decrypt the keystrokes. You really don’t have to though; there are only 256 possible encryption keys.

It appears I was quoted in a Fastcompany blog entry today….
2008 was the year that Web 2.0 became more mainstream. More ad agencies, businesses, and non-profits used Web 2.0 tools as a way to build community and relationships, cross promote products and issues, and integrate their online and offline marketing strategies. Some like Zappos were extremely successful and nailed their Web 2.0 strategy while others like the makers of Motrin were burned by mommy bloggers for not doing proper research on their target audience.With the economy in a slump and budgets being cut in traditional print and TV advertising campaigns many will be looking to the Web 2.0 world to reach their constituents. So what should be on your Web 2.0 radar for 2009? Web 2.0 gurus give you the low down.
