The 4-Hour Everything: How Tim Ferriss Tracks His Life’s Data (Interview with Wired’s Clive Thompson)

This is a short 20-minute interview from this week’s WIRED “Living By Numbers” Health Conference. It was a great event, and one of my favorite writers, Clive Thompson, interviewed me on how I track my life. Included are questions about the future of self-experimentation.
What would you like to know more about? Please let me know in the comments.

Plastic Cutter

This is just a cheap little knife with a sharp draw blade. You use it to score acrylic sheets (up to 1/4 inch or 6 mm) to cut them by snapping them along the score line like glass. This is easier than using a saw. Any make will do; this is a cheap one.

Stoicism for Modern Stresses: 5 Lessons from Cato

The philosophical school of Stoicism is, I believe, the perfect operating system for thriving in high-stress environments. For entrepreneurs, it’s a godsend.
Both Seneca and Marcus Aurelius have been extensively written about elsewhere. But what of Cato, about whom Dante said, “And what earthly man was more worthy to signify God than Cato?”
One of my favorite anecdotes of Cato is from Plutarch. I quote it often (see “Practical Pessimism“):
“Seeing the lightest and gayest purple was then most in fashion, he would always wear that which was the nearest black; and he would often go out of doors, after his morning meal, without either shoes or tunic; not that he sought vain-glory from such novelties, but he would accustom himself to be ashamed only of what deserves shame, and to despise all other sorts of disgrace.”
The following article was written by Rob Goodman and Jimmy Soni. At age 22, Rob Goodman became the speechwriter for Senator Chris Dodd, and then moved on to be the speechwriter f…

C.S. Lewis — The Conservative Worshiper

One of the clearest statements of what might be termed the “conservative” position on the practice of worship was made by C.S. Lewis in Letters to Malcolm: Chiefly on Prayer.
I wonder how you respond to it.

“It looks as if they [innovative clergy] believed people can be lured to go to church by incessant brightenings, lightenings, lengthenings, abridgements, simplifications, and complications of the service. And it is probably true that a new, keen vicar will usually be able to form within his parish a minority who are in favour of his innovations. The majority, I believe, never are. Those who remain — many give up churchgoing altogether — merely endure.

Laser power system keeps UAVs flying indefinitely

Drone technology is driving the aerospace industry as companies trip over each other trying to develop the next big thing. Here’s a good example of what we’re talking about. Lasers can no be used to keep a UAV in the air indefinitely. The trick is to add an array of photovoltaic cells specifically tuned to an IR laser’s wavelength. A ground system then directs a high-intensity laser beam onto the aircraft’s cell array to transfer energy while in flight.
After the break you can catch a video from a trade show where a Lockheed Martin employee describes the successful testing of such a system. But there’s a lot more information available in the white paper (PDF) which Laser Motive has released. They’re the folks behind the technology who have teamed up with LM to implement the system. The laser unit on the ground can track a UAV visually, but there is also a method of using GPS coordinates to do so in the case of overcast skies.

Wearable Raspberry Pi turns you into the Borg

The Hoboken hackerspace, MakerBar, recently hosted a very special guest – [Rob Bishop] from the Raspberry Pi Foundation. Wanting to impress [Rob], [Zach] and a few others from MakerBar put together a wearable computer based on the Raspberry Pi in just a few hours.
Putting a Raspi, small Bluetooth keyboard and mouse combo, and a USB charger equipped with lithium-ion battery wasn’t that hard. The tricky part was finding a wearable display. Luckily, [Zach] had a pair of MyVu Crystal video glasses lying around and after a tricky bit of dissassembly, the folks at MakerBar had a completely wearable computer.
Apart from the RCA cable connecting the Raspi to the glasses, the project is completely wireless; with a small webcam also mounted to the display, the Pi in the Face could easily be a platform for figuring out what to do with Google Glass.
[Zach] said the entire setup could be reconstructed for about $100, a fair price for being turned in to [Locutus] of Borg

Time vs. Money: When to trade DOWN

When I graduated from college, I had a job offer from Google. They were great, saying, “You’ve been in school for 5 years…you should take a break!” I was like, “Oh I know, I was already planning it.”
Google: “So how long do you need? 2 weeks?”
Me: “Uh, no. See you in 3 months.”
Google: “That’s not gonna work for us…how about 4 weeks?”
Me: “No, I’ve been in school for 5 years. I love you but I need a break. See you in 3 months.”
During that time, I launched a product called PBwiki with a friend, which ended up taking off. Over the next couple months, I agonized over whether to turn down Google or walk away from this new startup.
I ended up walking away from Google.

Once Upon A Christian Nation

With last night’s debate still fresh in our minds, I thought we might step away from our look at church music this morning to consider this essay from Craig Bubeck. 
I love my country . . . I mean, you gotta’, right? Even during its awkward cycles of uninhibited vitriol, come election time (with its debates). In so many regards, its ethos and heritage are so ideal driven, so optimistic, and yet so . . . practiced. What I love is its being foremost about the people—their lives, their liberty, and (imagine) their pursuit of happiness. From the jaded vantage point of a fallen and corrupt human history, it’s only reasonable to marvel at the great “experiment’s” miraculous conception, never mind survival.
Even so, I can’t say I’ve been particularly zealous in insisting it is “Christian.” To a great many of my younger brothers and sisters in Christ, this begs the jaded question. They’ll shrug: What does that even mean, “Christian nation”?
