LED lights are about more than just energy efficiency. The new bulbs are meant to last for a very long time--25,000 hours. The average light bulb is estimated to be used about 1.6 hours per day. At that rate, LED bulbs can last up to 42 years!
This story from the New Yorker discusses an incandescent light bulb that dates to 1901 that is still burning today (it is left on at all times). It goes through the history of light bulbs and how this was the first time that an industry went through deliberate efforts to "break" their products prematurely in order to create turnover in their markets.

Why charcoal grilling tastes better than gas
There is a scientific explanation for the reason why charcoal grilling has a distinctive flavor that is different from gas.
Two paragraphs explain the critical part of the magic:

Two paragraphs explain the critical part of the magic:
Ironically enough, it’s the volatile compounds in the food, not in the briquettes, that are responsible for charcoal grilling’s distinct flavors. As the meat heats up, it releases drippings that strike the super-hot charcoal and combust with a tsss and a burst of flame (check it out in the video above—it’s beautiful). Those drippings are full of fats and oils and sugars and proteins that vaporize and rise back up into the meat whence they came.
That’s how grilling over charcoal gives you that wonderful flavor. The briquettes themselves are just middlemen, not the flavor-makers. The more you drip, the more the flavor builds.

Great article on Human Behavior Hacks
Found an amazing article on ways to use human behavior in your favor.
Build Your User Base with These Human Behavior Hacks
Framed as a discussion on how startup companies can best develop new products or services that can succeed, it provides some clear examples on how to tease out the truth from your target audience.
One of the critical recommendations is to avoid the trap where you believe you know exactly what your customer is looking for. Without data to support your suppositions, you could be dangerously exposed. This could be a fatal error if you bet on a solution and you turn out to be wrong!
Confirmation bias is perhaps the most common obstacle.
The author recommends having a neutral party take notes so that the interviewer can concentrate fully on the interview. At the end, they can compare notes. The note taker may be able to point out subtle changes in tone or interpretation.
The PM might say, “I think they really liked our solution.” And the engineer, freed up to really hear the call from a different perspective, might reply, “I’m pretty sure they were just being polite.” That’s how you counteract bias. You start small and take it interaction by interaction.
Other issues are hindsight bias (I knew it would work all along), supportive bias (sunk cost defense) or hyperbolic discounting (more weight to now than the future).
One other surprising method is to avoid asking about the future. Instead, ask about what people have done. They are more likely to be honest.
Overall, I thought it was excellent!

Confirmation bias is perhaps the most common obstacle.
Confirmation bias manifests in a few ways:
- Only talking to people we think will agree with us.
- Writing off people who don’t agree with us as idiots or haters.
- Asking questions designed to support our hypothesis.

One other surprising method is to avoid asking about the future. Instead, ask about what people have done. They are more likely to be honest.
You want to capture quantitative data about what happened in the past. It won’t lie to you.
This is an area that’s especially sensitive to negative judgment from others. People want to idealize their future selves. They want to believe in their ability to work toward those goals. So when faced with past behavior that runs contrary, they might get defensive. They might be dishonest. You have to phrase your questions to make it acceptable for people to give answers that may not be perfect or socially acceptable.
“Instead of asking someone if they let their kids use an iPad (an assumed negative behavior), ask them how many days in the past week their kids used an iPad,” says Alvarez. “Most people will answer honestly because you already implied that the answer won’t be zero — and that it’s not zero for the other people you’re talking to.”
Overall, I thought it was excellent!

Ambiguous cylinder illusion
I just saw this and it was rather impressive.
Even after watching it a few times, it's still difficult to believe that it isn't some CGI trickery.
This is how it works:

Nagging limitations
At some point on our recent driving trip, I strained some muscles in my lower back. This has happened before on long drives. I'm not sure if it is tied to an awkward position held for long stretches of time or perhaps a misstep at some point. Whatever the cause, it was excruciating.
I first noticed it when I tried to get out of the car. After I opened the door, I went to take a step out and realized that my body did not want to move in the way that I intended. Waves of pain shot from my lower back down my leg and back up to my brain. I gingerly forced myself out of the car in the way that an elderly person might.
Over the course of the next few days, I had the family help me. My wife went first and helped to ease some of the knots. There was temporary relief, but it soon returned. My younger son took his turn standing on some of the worst areas. Again, it helped for a while but the discomfort was soon back.
It's been over a week now. I had to stop working out temporarily because the pain was too great. The last two days, I have been able to walk on the treadmill for a few miles. I feel as if I am getting closer to normal. As I type this out, there is still a dull ache and a twinge in my lower back.
It's weird to think that only about ten days ago, I was feeling really good. There were absolutely no concerns of any sort and no pain whatsoever. I'm not sure what triggered this phenomenon, but I hope it doesn't come back for a very long time!
All in all, incidents like these help remind you that your health is far more fragile than you think. It also makes you appreciate even more the good things that you do have in your life!

Take a simple idea and take it seriously
Interesting column today on the Motley Fool.
Take a Simple Idea and Take it Seriously
The article points out how companies that seem to do one or two things but do them really well have outperformed big name (read: "sexy") stocks over time.
The article summarizes with a few key points. Here is the one that resonated most to me:
Value isn't necessarily created by innovation or complexity. It's created by solving people's everyday problems for the longest period of time. This is why toilet paper and garlic powder have been better investments than some of the most innovative technology companies. Lots of technology has solved people's problems, but few to the degree toothpaste and deodorant have, and will continue to do for the indefinite future.
I couldn't agree more!
Take a Simple Idea and Take it Seriously
The article points out how companies that seem to do one or two things but do them really well have outperformed big name (read: "sexy") stocks over time.
McCormick makes garlic powder. Its stock is up 1,423% since 1995. Oracle has a near-monopoly database management software. Its stock is up 1,419% since 1995.
V.F. Corp makes jeans and flip-flops. Its stock is up 1,444% since 1995. Cisco Systems connects the entire world together in one place. Its stock is up 1,018% since 1995.
Valspar makes industrial coatings, and has returned 1,521% since 1995. Adobe makes some of the most popular software in the world, and has returned 1,230%.
Google is one of the most exciting companies of all time. Its stock is up 345% since 2008. Altria makes cigarettes in the rapidly declining U.S. market. Its stock is up 494% since 2008.
I cherry-picked these examples, but the idea holds up with broad indexes. The best-performing industry over the last 50 years, by far, is consumer staples – things like food, toothpaste, and toilet paper. The worst-performing industry, by far, is technology.

Fireworks
For the past 53 years, Walpole has put on an annual fireworks display on the 3rd of July. Thousands of people will gather informally near the center of town to watch the display. For a small town, they put on a rather impressive display. The show lasted nearly 30 minutes!
We had been invited to join the Little League team at the coach's house. He lives a short walk from the main viewing area. At one point, there were well over 100 people at his house. It was great to see so many young boys running around and having a good time.
I took some short phone video of the event. I didn't want to spend too much time capturing the event for fear of missing out. I do wish I had been able to catch some of the spectacular finish. The layers of colors in the explosions almost appeared to move closer and closer--as if they were nearly upon you! The intensity grew and grew for nearly a full minute. It was an awesome way to end the evening and likely the best one we have ever seen. What makes this event so special is that we are almost literally under the spots where they go off. At that distance, you can literally feel the booms as the shells explode!
