2TB Portable Drive Comparison


New 2TB portable drives formatted to Mac Journaled file system straight out of the box. Tested using Black Magic Design's Disk Speed Test with a Macbook Pro. Read and write speed was nearly identical for all drives except the internal drive.




The Seagate Backup Plus Slim drive is the winner on all dimensions: speed, price, size, weight though the Ultra is a little cheaper. The Silicon Power rugged armor disk is, well, pretty darn rugged!

The WD My Passport (old) line is a drive I have been using for about 9 months and is getting fairly full. I have not diagnosed whether the speed difference is because the file system/directory is getting full, or whether the new drives are about twice as fast.

I have the most experience with Western Digital Drives, and have never had one go bad over many years. I'm not sure how to assess longevity of these portable drives...I guess we'll have to wait and see.

Healthcare Emergency in Cabarete, Dominican Republic



Today is a historic day for sailboat racing with Team Oracle USA winning America's cup using a boat with a hydrofoil while the discussion in national news is all about Obama Care and the opening of the healthcare exchange and the American Healthcare system in general. Well, my story touches on both topics!

At a recent MaiTai event in Cabarete, Dominican Republic, I bought a super cool hydrofoil board from Nick at www.mhlcustom.com. Riding a foil board with a kite is a little bit tricky to learn - basically you have to get used to a lot of power coming from the bottom of your board, about a meter below your feet! At sea level  water is about 750 times as dense as air. The "wing" on the bottom of the foil is about 1 square foot of total area. "Air adjusted", that's equivalent to about 750 square feet of kite. A 10m kite is about 100 square feet, so the power from the board is seven times as strong as that of the kite. In reality, the power doesn't feel that disparate, probably because either I have a math error, logic error, or because the way the foil rides is very different than the way the kite flies. But in any case, the power coming off the foil is strong.


The conditions in Cabarete bay are nearly perfect for learning to foil board - small waves on the inside, sandy beaches, and in the mornings, light wind. On this particular morning, I was the only kiter on the water as a foil lets you ride in extremely light wind. I was somewhere between my first and second hour using the foil, and was just getting the hang of it. Just enough to get that initial "cocky confidence" that frequently results in trouble. I starting riding a bit faster than normal, and then fell downwind of the board. I thought I was clear of it, but about a second later, something hit my head.

I put my hand on my head and it was quickly covered with blood. The white pad on my foil started turning red as did my vision. Not really that big a deal: heads bleed a lot, way out of proportion to the pain or the severity of the injury. I was a few hundred meters out and started to body drag back to shore - foil under one arm, flying the kite with the other hand. 

I went to to Laural's kite school / shop and one of the instructors there said I should go to the hospital as I'll need stitches. Here I was in 3rd World country (at least according to this mapneeding healthcare. I was a bit worried! Laural showed up and took me to the local clinic - a small place right in downtown Cabarete called Playa Dorada Medical Center. 


I've had a number of cuts and other injuries - 6 stitches in Breckenridge, Colorado a couple of years ago, a rib dislocation issue in San Mateo, and a while back, tore an ACL playing soccer. In each of those cases, I sat in a waiting room at least an hour and the bill was over $2K. In the case of the ACL, I visited four emergency rooms and finally ended up at Stanford. After sitting around for over an hour, I walked - limped, actually - out after I called a doctor friend who said he would see me in the morning and there was probably nothing they could do anyway, other than give me pain killers.

My worries about healthcare in the DR were unfounded. The doctor showed up almost immediately and put a few stitches in my head. He cleaned up some coral I had in my foot and advised me on an asthma issue. He prescribed some antibiotics which they gave me on the spot - I didn't have to go to a pharmacy and wait in another line as you do in the US.  

The doctor asked if I had health insurance. I said I did, and he said I am better off not using it! I didn't fully understand his explanation, but he said something about the hassle and cost of dealing with the insurers in the US, and in the end, my out of pocket would be MORE if I used my insurance than if I just paid the bill. I was a bit skeptical, until I saw the bill: $100 for the doctors time, the hospital time, the stitches, and whatever else. $91 for the medicine.

Total time spent: about 1 hour. 

I was back on the water by 2.

Without a doubt, this was the best healthcare "emergency" experience I have ever had. And it's not even close: the service was excellent, there was no wait, the price was incredible, and there were far fewer hassles and forms to fill out. I was pretty concerned when I was initially hurt - seeing red trying to get to shore - but in the end, the whole thing was a great experience given the situation.

In trying to find a link to the clinic I went to, I found another post with a similar story: http://turftosurf.com/why-americans-should-leave-usa-for-medical-care/. That story talks about a different hospital - I was an a small medical clinic, but the overall experience and conclusion are similar.

In the end, it's not that the healthcare in the DR is particularly good. It's that ours is particularly bad. I know we can do better - I hope we figure this one out before I'm too old and need some serious care!

What is more expensive – the gas to drive a mile in a Hummer or the wear and tear on a Tesla Roadster battery?


When I bought my Roadster, reports said that driving a roadster costs just a few cents for the electricity. What about the rest of the costs? If you look at just the battery, the current price of a new Roadster battery is $40,000 plus installation costs! The estimated battery life is about 100,000 miles (less if you drive less than about 12k miles per year since the battery degrades without driving). That’s 40 cents PER MILE in the BEST CASE, or, for $4.00 gas, the equivalent of 10 miles per gallon! And that’s just for the battery wear-and-tear.

To be clear, this is the equivalent of the gas tank, NOT the gas. For an electric car, the actual fuel is both the electricity and the battery wear and tear, and just the battery part costs 40 cents per mile. A Hummer gets about 12 mpg highway and 10 mpg city, so at $4.00 gas, costs a bit under 34 cents per gallon highway and 40 cents per mile city.

I love my Roadster as it occupies a unique point in the price/performance/reliability envelope for a sports car. That said, unless the battery aspects of electric vehicles undergo a major overhaul, the economics of the battery alone will make the technology impractical, particularly for more mass market cars such as the Model S or X. 

Perhaps the EPA will start measuring “MPG” on electric cars to include the wear and tear on the battery so it's easier to see what is going on.

As it turns out, the Hummer is nearly 20% cheaper to drive on the highway than the Roadster for just the gas when compared to the wear and tear on the Roadster battery.

That said, I love my Roadster and I'm a huge fan of Tesla, but worried about the economics required for even a moderate main-stream success.

Learning from the Chinese government

I was recently in China - when going through immigration you get to rate the immigration officer. There are four buttons ranging from smiley face to sad face where you can provide feedback as to the level of service you received. I don't know what they do with the data, but I clearly the immigration officer is aware of the feedback mechanism and probably does a better / nicer job as a result.

After we sold Core Mobility, I forgot to update the DMV of my address and the registration on my Tesla expired last December. A nice officer in Palo Alto reminded me of that with a ticket, and then two days later, I'm pulled over in Los Gatos for the same thing! Nuts! Four months of daily driving with no issue, and then two tickets in a week! Sure would have been nice to get those tickets a few months ago since the late fees alone on the registration renewal were over $500!

I told the second officer that I already had a ticket, but he said he is unable to verify that. Strike one! Let's see, in today's connected world they can't look up whether I received a ticket? I sure hope the systems for finding real criminals are better than that!

Anyway, I pay the $1500 for the registration and send all the info to the traffic court hoping it ends the matter. Unfortunately, they don't get an automatic notification after the registration is up to date, even though I have to both pay for the registration and have another officer sign off on the ticket.

The ticket was issued April 2nd and I mailed the proof of registration to the traffic court on April 7th, just before leaving for China.

When I got back, I found the following in my snail mail (address redacted to protect the guilty!):


More than a few things wrong with this picture!
1) The date on the letter is February 1, 2011. That's off by over 2 months!
2) The letter refers to a citation from April 12, 2011. From the point of view of when they got this, that's in the future! The date on the citation is April 2, 2011.
3) The letter head is a template that is not filled out. For example, Branch Name shows as FACILTY_NAME
4) The letter says that I may inquire about the status 45 days after the date on the letter. The date on the letter is incorrect, and 45 days after the time I received this back is after I am supposed to appear in court!

Our tax dollars at work. As Bill Gates said in his TED talk: State Budgets are huge expenditures that undergo very little scrutiny. Unfortunately, the same is true for other areas of state operations.

I'd really like to have a feedback mechanism like the Chinese immigration department has!

And, of course, don't forget to use speech to text transcription services from Speechpad!

Your help needed: who is this?

How much information is in a picture? What if you had 1000 people interpret the picture, creating that information? How about just finding out a few key pieces of information?

I once posted a "how-to" kiting video shot in Maui with an unknown rider, and heard back from the rider within a few days! That was an easy one, though - there just aren't that many kiters on Maui, and the community is closely linked. 

While on a boat in the Maldives, were were discussing how quickly we could track down someone in a picture that has a much broader search domain, and a bet evolved.



Setup: The pictures in this post were in the background of another picture (that included a kiter, of course!). They have been blown up and enhanced to better make out the relevant details. They were shot with a high resolution camera that included GPS tagging, so we know the time the picture was taken (5:07:05 PM local time - shortly before sunset), the location where it was taken (3 52.8661'0"N, 73 27.3889'0"E at sea level) and, of course, that they were taken in high resolution (4256 x 2832) so we could pull out the background.

We were discussing the power of crowd sourcing and the power and diversity of the crowd. Eventually a bet evolved: how long will it take to identify a dive shop given only some pictures? This boat is literally on the other side of the world from the US, in the South Male Atoll in the Maldives.

Here's what we know:
The pictures show the boat registration number and we have a blown up picture of presumably the dive master.


The satellite map is tagged with where the boat was seen in the South Male Atoll based on the GPS coordinates in the picture. The boat was heading north at the time and it looks like it's returning from a dive trip.



There is an MTurk job that points to this post and the associated geo-stamped pictures - assuming that information was kept in the upload - (we'll know soon enough - but the satellite picture and the coordinates in this post provide everything we need).

Cash for Clunkers: A Good Deal?

The cash for clunkers program cost tax payers $3 billion. In exchange, 700,000 Americans were able to get a new car at below market rates. Was this a good deal? Are there better ways to allocate this capital?

When making a cash outlay, one of the first questions should be to understand whether the money is being invested or spent. Expenses are things such as movies or dinners which have no residual economic value. Investments are things such as houses or stocks which generally have substantial residual, and even increasing, economic value. Cars are an interesting hybrid as they have residual value, but unless it becomes a collectors item, depreciates quickly and if not fully realized as an expense now, will become an expense as it’s fully depreciated over future years.

Providing discounted cars to a subset of Americans is something that benefits the few and has small, if negligible, ongoing economic value to the larger populace. The program was justified through the benefit of less pollution and better energy efficiency which benefits everyone, as well as spurring more auto sales to help struggling US auto makers.

If these are our goals: improve energy efficiency, reduce pollution, and help US auto makers, is there a better way to spend $3 billion? Rather than a one-time stimulus that benefits the few (one in 500), is there a program that can have on-going benefits for all Americans?

Tesla Motors, a US manufacturer of electric vehicles, recently announced installing five charging stations between San Francisco and LA so that their flagship car, the Tesla Roadster which has a 250 mile range, can make the trip. Total cost for these 5 charging stations: about $10000 each on average.

The energy dispensed by the charging station is free, justified by local merchants who foot the bill by driving traffic to their establishments. Roadster owners, who stop to charge their cars for three hours, will likely engage in commerce near the charging station. The cost of the electricity to charge the Roadster is around $2, so the merchants are paying $2 to have a potential customer in the vicinity for several hours looking for something to do.

Suppose we used the $3B for the clunkers program and built out electric charging stations instead? Could that achieve our goals of improving energy efficiency, reducing pollution, and helping US auto makers?

There are around 110,000 gas stations in the US. At the current price of $10,000 per charging station, we could install about 30,000 charging stations around the US. Assuming economies of scale, it’s not hard to imagine that 100,000 or more charging stations could be installed for the price of the clunkers program.

If we assume 50% or more of the cost of installing a charging station is labor, such a program would create a number of jobs, directly helping unemployment.

What we are left with is 50,000 to 100,000 free charging stations, subsidized by local merchants, to drive traffic to their stores. But what good does this do? Very few people can afford a Tesla!

This is actually where the large benefits take place. Over the last year, I have seen numerous companies that are building electric vehicles: bikes, motorcycles, and cars. In fact, there are over 100 companies that have been started to just build electric cars. With free charging stations covering the US, consumers will be very interested buying a new electric vehicle that takes advantage of this handout. And a number of entrepreneurs will be focused on building vehicles that can exploit the new grid, from a consumption as well as generation and storage standpoints. In short, we have created a new innovation platform.

But how do automakers benefit? Here we can look at other industries that have undergone a large technology leap, and examine what has happened. Recently, mobile phones went from being able to simply make basic calls to having cameras on them. This caused a rapid upgrade cycle, moving the average time a consumer keeps his phone from 24 months down to 18. The widespread availability of wireless data networks and high quality phone software is now causing another upgrade cycle to devices such as the iPhone and Android.

Whether these upgrades are captured by the existing players or new players depends on how well the companies are run, but in any case it’s a huge boon for the players who can get it right. Just look at Apple’s stock price or the buzz Google is getting for its Android operating system.

With this approach, for the same $3B, we would have:
• a national charging grid that enables electric vehicles to be charged at as many locations as the corner gas station
• an opportunity for merchants to drive traffic to their stores by subsidizing the energy using to charge the vehicles
• a massive upgrade cycle as entrepreneurs and consumers find innovative ways to use the electric grid
• a spike in employment as factories, stores, and other infrastructure are upgraded and built to fulfill the demand for electric vehicles
• much cleaner environment, as electric power is substantially cleaner than the internal combustion engine
• most likely, safer roads, as electric vehicles tend to be lighter and built out of modern materials
• drive innovation in battery and grid storage technologies, reducing costs and further increasing efficiency
• a tremendous opportunity for existing as well as new vehicle manufacturers to fill the demand to drive profits and employment

Rather than allocate another $3B, this program could be paid for via a national gas tax of two cents/gallon. This would further incentivize consumers to move toward electric vehicles since it would further pressure operating cost differences between gas and electricity, and bring prices closer in line with true costs, when deficits, national defense and pollution are taken into account.

Overall, upgrading the grid is likely a much better way to invest tax payer dollars and reap long term rewards compared to subsidizing car purchases for Americans who own “clunkers”.

John Mauldin 12/4/2009 newsletter:
All we did with this "Cash for Clunkers" thing was move cars forward that would have been bought later. You're not increasing sales down the road. Yeah, you're taking cars off the road and spare parts and stuff, but I think it's kind of a silly investment in dollars. But, what's $3 billion when we're wasting a trillion here and a trillion there? Still, it's disappointing.

Bruce Leak 12/9/2009 email:
Politics isn't about efficient use of capital. It is about special interest groups and playing to populace emotions. Subsidizing "green" car purchases pleases car manufacturers, suppliers, finance institutions, labor unions, dealers, environmentalists, local and state tax authorities, scrap recyclers and consumers. What's not to like?
