Depending on the cloud

Sunday, October 11th, 2009

Continuing the theme of over reliance on technology, owners of the T-Mobile Sidekick smart cell phone got a rude lesson this week.  The Sidekick stores its data “safely” in a huge storage system loosely termed “the cloud” – meaning some huge mass of data storage on the internet out there “somewhere” storing your data, but you don’t need to trouble yourself with the details.  You’re safe.  (think Gmail’s “2GB of storage for every user” for another example of storing data in “the cloud”)

As those of you with large disks have learned, the more stuff you have, the harder and less practical it is to back it all up – especially if you are backing it up to another computer over the internet.   The remote backup/recovery services you hear advertised can take as much as a month to complete the first backup of your computer if you have a lot of stuff, even on a good DSL connection.  A typical 156kb upstream ADSL connection can transfer about 1 GB of data per day.

So the cloud must be failsafe on its own.   Disk must be in RAID arrays that cannot fail and lose data.   The idea of ever backing up the entire cloud to one central place is not practical, especially if the data has to be up 24/7 for constant updating.  Portions of the cloud must back up each other, and some centrally run control system keeps track of what data is where and what other part of the cloud is its backup.

So the early rumors are the Sidekick server(s) were given a software upgrade, and the upgrade failed and wiped out every server.   The result was a catastrophic loss of all data with basically no hope of recovering any of it.   There is no backup, because it isn’t possible or practical to do it.

[I wonder if the data was encrypted with 128 bit encryption, and they lost the key :)]

Barack Obama, M.D.

Saturday, September 26th, 2009

Barack Obama has declared that it would greatly improve health care if women got more mammograms, and save us a lot of money in reduced health care costs.

While some feminists have been pushing this notion as an agenda item, the science says otherwise.   Routine mammograms INCREASE the risk of breast cancer because of the radiation used in the procedue – which more than offsets the value of detecting a few cancers a little bit earlier.

Study

There is nothing more dangerous than a man who believes things are true soley because he said them.

It will be interesting to see how Dr Dean Edell handles this situation – he’s long been an advocate of keeping politicians away from driving decision making in medicine.   Will Dr Edell take on President Obama’s uninformed statements and beliefs?

Instinct vs Science

Wednesday, September 23rd, 2009

About two months ago, I wrote a little screed which got me quoted in a newspaper that “I’m fat, I know I’m fat, and I don’t care that you don’t like it”.  The point was that people in talk radio (and some politicians) are feeding the notion that fat people are what are causing health care costs to go up.  The most blatant example of this was Michael Savage advocating that “fat people” be denied  health care insurance by government edict (Mr Conservative?).

This attitude also is widely held in the medical community despite the fact that the science and data says otherwise.  Having just been hospitalized for fainting and immediately being put on high blood pressure medication and cholesterol lowering medications while I was literally strapped in a bed and unable to have a rational discussion, I feel ever more strongly now about this subject.

The “gold standard” for estimating risk of heart disease and stroke is the Framingham Risk Score.   I’m 53, not diabetic, have never smoked, not African American, no family history of premature death due to heart attacks,  my total cholesterol is under 200, my systolic blood pressure is below 140 without taking any medications.   My 10 year risk of having a heart attack is about 5% (that’s 1/2 of 1% per year – most of which is probably when I’m 60+).  That makes my risk of having a stroke or a heart attack significantly less than the average person my age – but people see a 300 pound man and their instinct says “high heart attack risk” when in fact that’s not based in fact.  Add to this that I was on a heart monitor for 4 days and didn’t have so much as a flutter and the sonogram showed my heart being normal in the way it  beats and its size (no early signs of congestive heart failure) and no heart murmer or other indication of heart disease or valve damage.

So now I’m still on a blood pressure medication to lower my systolic pressure from the 140 range to the 120 range, despite the fact that if you look at the Framingham scale that 145 untreated and 120 treated have identical risk profiles for heart attack and stroke.  So maybe you’re thinking, well it can’t hurt anything to take it….   One of the side effects of lisinipril/hctx is that it can cause symptoms of low blood pressure – fainting and dizziness – which is the reason I wound up in the hospital in the first place – in addition to causing weight GAIN.

You’ll notice that weight and BMI (body mass index) are not factors  – there is a reason for that – BMI is not an indicator of heart attack/stroke risk – in fact the highest risk is in the people who have very low BMIs.  To have a low BMI, you have to have very little muscle tissue which means you are highly inactive and a good chance you’re a smoker.  People who are moderately obese have a lower risk than those of normal weight.    The real measurement of risk is comparing the size of your waist to the size of your hips, which nobody has measured yet.

So looking to the future when the Health Care Czar is empowered to make rules based on politics, not science – if I make the above case to my doctor and he insists that I continue to take this medication despite all of the scientific data that says he’s wrong and I become “non compliant” with my doctor’s “orders”, what will the government do next?

Natural Gas and cars

Sunday, September 20th, 2009

Bob Brinker has been on a rant for months now that the solution to all our imported oil problems is to convert to using natural gas for cars, since the U.S. is drowning in domestic natural gas supplies.   Let’s look at the numbers

The U.S. currently consumes about 20 million barrels day of oil, the largest portion of which is used in transportation – which includes airplanes, trucks, and trains.  In 2008, we used about 132 billion gallons of gasoline.

Gasoline contains about 125,000 BTUs per gallon. 
8 gallons of gasoline = 1000 cubic ft (mcf) of natural gas = 1M BTUs
1 mcf delivered to your residence costs about $13 at current rates (about $1.62/gallon if you assume the engines are equally efficient)

The total annual consumption of natural gas for all purposes is about 23 million million cubic feet, or the energy equivalent of 184 billion gallons of gasoline.

Known U.S. reserves of natural gas are around 800,000 billion cubic feet, or the energy equivalent of 5.6 trillion gallons of gasoline, which would last about 41 years if all  gasoline consumption was switched to natural gas (and no new gas was found).

Natural gas gives off CO2 – it does nothing about so-called global warming.

Let me know if I dropped some zeroes…. :)

BP has “giant find” in Gulf of Mexico

Wednesday, September 2nd, 2009

British Petroleum has another very significant oil find in the Gulf of Mexico, at a depth of 35,000 feet:

http://finance.yahoo.com/news/BP-announces-giant-oil-find-apf-2273328778.html?x=0&.v=1

All of these deep oil finds strongly suggest that oil is not based on decayed organic material at all, but a chemical process based on the heat and pressure of the molten core of the Earth creating new oil constantly – throwing the entire notion of “peak oil” and “the last barrel of oil” out the window for those who still have open minds about science.

Everywhere, all the time Wireless

Sunday, August 30th, 2009

I’ve just spent 5 days experiencing a revolution in wireless technology – it probably isn’t that “new”, but it was new to me.   I’ve written before about how LTE or WiMax is going to change every aspect of our lives very soon in ways we don’t even think about yet.

When I was in the hospital, I was put on a cardiac monitor that monitored every little pitter patter of my heart 24 hours a day.   It is a device about the size of an iphone that is in constant contact with the monitoring center via wireless (which in theory could be anywhere in the world).   If a lead came loose, within seconds a page would go out to the nurse telling them to go to the room and fix the problem.   Had anything “exciting” shown up on the monitor (it didn’t), the response would have been in seconds to start to deal with an issue with a real time display in front of a doctor with the skills to make informed decisions in real time.

Now broaden that picture out to be that someone with a heart issue could wear this device and go pretty much anywhere in an entire city, and be just as much in touch, including the ability of a doctor to remotely intervene (perhaps adjust a pacemaker or zap with an implanted defibrillator to restart a heart).

This technology has great potential to do wonderful things – but it also could be the technology that enslaves us if used by the wrong people with the wrong motivations. 

It’s critical that the government recognize that trust is the key for any solution.  Trying to beat people into submission without adequate thought and discussion will result in failure and extreme danger to the future.  I’m hoping the adults are beginning to take control of the process and we can stop with the “emergency” crap and have some balanced rationale dialog soon.

Bankruptcy Watch – First United Ethanol

Friday, August 21st, 2009

Just one of many ethanol plants that have been built that make no economic sense – “because the government said we had to”.

WiMax vs LTE: the contest has begun

Tuesday, August 18th, 2009

Even if you don’t know what means, it is going to change the rest of your life, whether you want it to or not.

WiMax and LTE are two competing technologies being rolled out into the real world to provide inexpensive “High Speed Internet Anywhere” service.  This is similar to the VHS vs Betamax showdown, which VHS ultimately won, even though many people believe that Betamax was the better technology.

Sprint/Clearwire turned on WiMax this week (August 2009) in Atlanta, Las Vegas and Portland, Oregon.   Sprint has about a six month lead on LTE, with several months of experience already in Baltimore.  Sprint’s main partner is Comcast, which can help them with building out the transmitter network in a city and backhaul capability.

Most of the other forces are lined up behind LTE – AT&T and Verizon being the big players… but they are only now starting their pilot programs.

Once WiMax and/or LTE are widely deployed, cell phones will begin to use its IP based phone capabilities.    The one area where WiMax has spent a lot of their effort is to ensure that a WiMax device in a car traveling at 60 MPH will work seamlessly as it hands off between cell towers.   Time will tell if that gives it the edge over LTE.

But no matter which technology “wins”, the Internet being “everywhere” very inexpensively will change the use of computers and computer like devices just as much as cell phones have changed the telephone business.

Lithium Ion Battery Duty Cycles

Friday, August 14th, 2009

Barack Obama, the Science President, is staking the future of America, and especially that of our government car company GM, on the Volt electric car, which uses lithium ion batteries, that can be recharged by a small electric motor if the battery gets low.

A commenter on a news story pointed out that the lithium battery pack will have a life of only 1,000 duty cycles before it must be replaced, which the person believes will cost about $15,000.    If you use your Volt to go to work and back every day and nothing else (2 cycles/day x 5 days/week X 50 weeks),  at the end of 2 years, your batteries will be useless.   They will start to lose range long before they die completely, which means the 40 mpg gasoline engine kicks in, defeating the entire purpose of the electric car.

But 1000 is probably way too optimistic.  

http://batteryuniversity.com/parttwo-34.htm

But lets say that is accurate.   Instead of your 40 mile commute costing $1 in electricity, the cost of using up the batteries adds another $15.00, or in the ballpark of comparison to gasoline an additional $10 per gallon.

GM claims to have “magic” proprietary computer software that will allow the batteries to last 10 years:

http://gm-volt.com/2009/01/23/gm-qa-with-bob-kruse-on-the-chevy-volts-batteries/

(How did they determine that in less than 10 years?)

President Obama makes a big deal that he’s the “Smart” president.  Answer that one, smart guy.

If you get past that issue, Lithium ion batteries are dependent on lithium that is only commercially viable in one mine in the world, lose their ability to deliver current if they get too hot, and are a significant fire and explosion hazard.    There is also currently no technology to recycle lithium ion batteries.

23 8-11 ?

Tuesday, August 4th, 2009

If you’ve visited a Clear Channel radio station in the last few days, you probably were greeted by a vague ad showing the picture of an electric outlet, and the message 23  8-11.

Pretty odd, huh?

If you click on the ad, you’re taken to the Chevrolet web site.  After waiting about 3 minutes for the site to load, there is nothing on the web site.   The logical subject of the ad is the Chevrolet Volt.   I’ll guess that 8-11 is August 11, the date for some announcement.

23 is either a reference to the price ($23k) or the number of miles the Volt will go before you need to call a tow truck.

Plugin Electric cars sound like a great idea if you’re Ed Begley – you are not constrained by cost, you live in a place that never gets cold, and you are the only one in the city plugging your car into the electric grid.

But let more than a few people start driving plugin electrics, and you’ll start seeing serious problems with shortages in electric power generation and distribution.   Shortages in power will increase the costs for electricity, even for those people who don’t buy a plug-in electric car.

We’re just on the edge of seeing the unintended consequences of plugin electric cars, especially if we remain in idle about building new nuclear power plants.
