Is Sitting a Lethal Activity?
April 21st, 2011, 6 comments
This is your body on chairs: Electrical activity in the muscles drops — “the muscles go as silent as those of a dead horse,” Hamilton says — leading to a cascade of harmful metabolic effects. Your calorie-burning rate immediately plunges to about one per minute, a third of what it would be if you got up and walked. Insulin effectiveness drops within a single day, and the risk of developing Type 2 diabetes rises. So does the risk of being obese. The enzymes responsible for breaking down lipids and triglycerides — for “vacuuming up fat out of the bloodstream,” as Hamilton puts it — plunge, which in turn causes the levels of good (HDL) cholesterol to fall.
Like Elton John, I'm still standing—at my desk, that is—and I love it. If I had an extra five grand laying around, I'd buy one of these swanky 2MPH "sit-to-walkstation" treadmill desks, too.
I’m Getting an iPad 2
March 2nd, 2011, 14 comments
Ever since I sold my Kindle, I've been set on buying a tablet computer to read books, long web articles, and watch video. I waited to hear what the newest offerings would be from Apple and Google to make a decision. The Motorola Xoom with Honeycomb is tempting, but now that I've seen the iPad 2, I'm sold. Three reasons: 1. Generally I think it's prudent to wait for 2nd gen products. The iPad has been on the market for a full year now, so iPad-ready apps like Flipboard have had time to become available and mature. 2. I want to get back to using iOS seriously so I can make informed comparisons between it and Android. 3. The iPad is the superior tablet on the market right now in terms of form factor (it's thinner and lighter, though the screen is smaller), battery life, and price. Having an iPad will also kickstart my Todo.txt Touch app development for iOS—I'm only motivated to build things I actually use. Update: Also, have you seen the smart cover? That thing looks awesome.

I spend about 45 to 50 hours a week working on my computer. Up until a week ago, I did that work sitting on my ever-expanding behind.
Last Monday I adjusted my desk to standing height (pictured right). I spent the week working on my feet, and I'm never going back to a sitdown desk again. Here are some questions and answers about the change.
What made you switch to a standing desk?
Ever since I wrote about a "treadputer" treadmill desk at Lifehacker in May of 2006, I've been curious about and inspired by alternative desk setups. My workday—which consists almost entirely of typing on or talking into a computer—is completely sedentary, and is a big part of the reason I'm more than 20 pounds overweight. Burning more calories while I work is a better use of that time.
Building or buying a treadputer is too expensive an undertaking for something I'm not sure I'll like or even have the space to accomodate. A standing desk, however, is doable. In July of 2010 I featured an Ikea Jerker treadmill desk, and mentioned I might just adjust my Jerker to standing height. This has been something I've been thinking about a long time.
Three straws finally broke the camel's back. First, I'm using RescueTime to monitor how I spend my time on my computer, and the weekly report made me realize how many hours I really do spend sitting down (week before last: 48). Second, I'm actively working on losing weight right now, and this seemed like a small way to add to the effort (down 12 pounds in 3 months so far). Finally, Macworld posted a guide to setting up a treadmill desk, and unequivocally recommended that you go from sitting to standing to walking, not straight from sitting to walking. That did it.

Nerd Holiday Gift Guide, the Lightning Edition
December 10th, 2010, 2 comments
A few people have asked what I want/what they should give to nerds they love for the holidays, so here are a few ideas off the top: a DonorsChoose.org gift card (your recipient will get handwritten thank-you letters from the students it benefits, too); a Fitbit ($99, been loving the charts and insights from mine); 23andme DNA analysis ($400 off holiday discount right now); an Angry Bird (throw in a slingshot for extra fun); The Complete Android Guide (disclosure: Kevin's my pal but it's also a really good book); anything cool on Kickstarter or Etsy (like the LunaTik iPod nano watch kit or this awesome MacBook decal); a pro subscription to a great webapp, like LastPass, Netflix, Flickr, Pandora One, TripIt Pro, or Dropbox. Also, the item that will be on every single tech gift guide and wishlist: the Kinect, which makes me forget I'm sweating and flailing at all, and sore in places I didn't know I had musculature. What are you wanting/buying/recommending for the holidays? Do tell in the comments. Note: nobody paid me to mention anything listed here. It's all stuff I either own and love or want myself.

My fellow Lifehacker Kevin Purdy has just published The Complete Android Guide, a soup-to-nuts how-to book on making the most of that Android-powered computer in your pocket. The book is available to browse freely online, as a $9 PDF or ePub file, and in print for $20. (This week only, if you follow @completeandroid on Twitter and send them a direct message, you'll get a 20% discount code.)
Congratulations to Kevin for publishing his first book, and to our publisher 3ones for continuing this iterative, collaborative tech book publishing model that we started with The Complete Guide to Google Wave.
I look forward to watching this book evolve as Android does, and also, asking Kevin all my hardest Android questions.

Email, IM and the web is a huge distraction, especially for those with short attention spans. My new friend Clay Johnson uses interval training techniques to lengthen his attention span the same way he trained his body to run a marathon. Clay writes:
Paying attention, for long periods of time, is a form of endurance athleticism. Like running a marathon, it requires practice and training to get the most out of it. It is as much Twitter’s fault that you have a short attention span as it is your closet’s fault it doesn’t have any running shoes in it. If you want the ability to focus on things for a long period of time, you need attention fitness.
Clay raises his attention fitness level several ways: by using a timer for work sprints (this works; I do it), by ditching his second monitor and stashing apps like Twitter and email in a separate virtual desktop that he hides while he works, by keeping his browser tab count down to a minimum, and by listening to lyric-free music. He's also looking into a standing desk. Test out your attention fitness level by seeing if you can read his post in its entirety--it's lengthy but full of interesting material that supports his approach.

The muscle soreness I'm experiencing today after walking around Comic-Con all weekend made me realize: I've got to incorporate more standing and walking into my daily routine. Maybe a treadmill desk? There are some expensive desks made to fit over a treadmill (sold separately), but someone on Hacker News modified an IKEA Jerker desk to do the job. The discontinued but beloved model of desk, which I already own, plus one of those utilitarian wire shelving units gives you a wide monitor stand with plenty of component/wire storage and keyboard and mouse room. Click on the image to see the whole setup. It's not the prettiest thing in the world, but it looks really tempting to try. The owner says:
Coding while walking works fine for me. As far as the mechanics, it's not hard to walk and type at the same time. 2MPH isn't very fast. I can't draw with the mouse while walking, so the occasional graphics work has to be done standing. Mentally, the consistent motion sometimes helps with flow, sometimes not. It's hard to tell, but switching between walking and standing seems to be enough for me to support the various required mental states. I've been doing this for about two months now, and while I have no hard data, I've done what I consider to be some of my best and most creative work ever in the last two weeks, so worst-case the walking isn't too great an obstacle to my coding. And this is indeed a huge improvement for my back over both sitting and standing.
I pace while I think, so this whole walking-while-typing thing is something I'd love to try. For now, I may just adjust my Jerker tabletop to standing position, and try that for awhile, before making the treadmill investment.

Steve Jobs announced the iPhone 4 yesterday in his WWDC keynote, and it's a gorgeous device with software upgrades that include multitasking, a video chat app called FaceTime, and more. I'm still a happy Android user, but I have to hand it to Apple. They continue to school the industry on aesthetics and marketing. Case in point: the FaceTime demo video.

TWiG: The Un-iPad Episode

Hopefully better late than never: in this week's episode of TWiG, Jeff reboxes his iPad to return to the store, we talk Twitter developer relations, and my tip of the week was a web front end to the Android Market, at thanks to doubleTwist. ∞ April 16th, 2010, 1 comment

A few months back I bought Brian Tracy's Eat That Frog--a great book about beating procrastination that I cited in a recent Fast Company video--on my Kindle. Today I got an interesting email from Amazon. To quote:
We're writing about your recent Kindle purchase of Eat That Frog!: 21 Great Ways to Stop Procrastinating and Get More Done in Less Time by Brian Tracy. The version you received contained some errors that have been corrected.
An updated version of Eat That Frog!: 21 Great Ways to Stop Procrastinating and Get More Done in Less Time is now available. It’s important to note that when we send you the updated version, you will lose any highlights, your last page read, and bookmarks made in your current version and the locations of any notes may not match the updated copy of the book.
The whole part about my losing highlights and bookmarks stinks. But Amazon reaching down into my Kindle and correcting errors in a book I bought months ago? Wacky!
Update, 4/12/2010: I posted this in a rush last week and didn't include the entire text of the email, or fully-baked thoughts about it. To clarify: the updates to the book are indeed optional and opt-in. The email ends thusly:
If you wish to receive the updated version, please let us know via e-mail at amazonkindle-feedback@amazon.com.
We apologize for any inconvenience caused, and would like to thank you for your business with Amazon.
My apologies for making it sound like this update was not opt-in. While I wish Amazon would provide a diff between the revisions so I can see exactly what I'm getting when I ask for the update, they won't touch my book unless I ask them.
I’m Not Buying an iPad This Weekend
April 2nd, 2010, 7 comments
Even though I'm desperately curious how one looks and feels and works, I'm not buying an iPad--just yet, anyway. I'll head down to the Apple store and fondle one on Saturday, just before TWiG, so that I can talk about it on-air. But I'm already suffering from gadget overload, with a netbook and an iPod touch and the Nexus One and a Kindle, so bringing another gadget into the house just doesn't makes sense. I will buy a tablet in the next year or so--after I eBay my Kindle and my iPod touch and get to see some of the Android models in person, too. If you're on the fence about whether or not to succumb to the iPad, read this: Why You Shouldn't Buy an iPad (Yet).

"The iPad leaves me with the feeling that Apple’s interests and values going forward are deeply divergent from my own. The future of personal computing that the iPad shows us is both seductive and dystopian. It’s not a future I want to bring into my home." al3x on the iPad. Read it.

Based solely on live blogs and a choppy audio feed: Terrible name, gorgeous device, great price point. I may be an Apple critic, but I'm not made of stone--this thing is beautiful. Instantly my Kindle seems like a joke. Kottke may be right: The Kindle app plus Instapaper installed on the iPad may very well be a much better reading and browsing experience than the Kindle itself, plus you get everything else it does. Here's Apple's official iPad page. And you?
The Uncelebrated Engineer
January 11th, 2010, 7 comments
"We live in an engineered world. Every second of each day is mediated by some product created by a team of engineers. Your clothes are made on machines that are astonishing to watch in action. A humming infrastructure feeds power, water, and data into our homes. No matter what sort of transportation we use, from the bicycle to spaceship, it is the product of an obscure group of engineers. This Christmas season electronics flew off the shelves. How many teenagers ever stop to think about the design efforts poured into that iPod or Wii?" [Embedded.com via]

BillShrink hits it out of the park with a handy infographic which compares the cost and features of the current generation of smartphones: the Nexus One, the Palm Pre, the Motorola Droid, and the iPhone 3GS.
Looking at this you realize 1.) there's no clear winner in the bunch feature-wise and 2.) we all spend a ridiculous amount of money on mobile phones and service. My only nitpick with this chart is that the T-Mobile/Nexus One "Average Usage" plan should be listed at $79.99 a month, not $89.99 (unless they're counting taxes and fees). Update: BillShrink has updated this graphic to correct prices. Head inside and click to enlarge the big picture to check it out.
