"One death is a tragedy; one million is a statistic." - Joseph Stalin 

Researchers were curious about generosity in the way of donations to charitable causes. 
There would seem to be a correlation to the level of generosity when it has a face; a face reflecting the suffering. You may have heard that sometimes you "have to put a face to name" to make it matter. It turns out to be very true. John and Jane Doe see a plea for a donation to save needy children. The plea wants money to help save children by providing general life saving things: medicine, food, clean water, shelter, maybe even education, if there is enough left over. Save more with a higher donation. It's simple math really, and we have seen it in the big box stores when we stock up on items. Buy bulk, pay less per item.  It works that way with helping people too. The more money is donated, the more people are saved. So it would figure, by that reasoning, that if you are told your generous donation of x will save 1,000 children, you would be inclined to save that number. But that is not how our brains work. That 1,000 is a statistic. The numbers somehow make our brains just say "Nope". 
Do you want to save kids? Of course you do. Do you want to save lots of kids? Sure you do. Do you want to save this particular kid that has a picture and a life story and will write you a gratifying letter saying thank you? OH HELL YEAH!
Face recognition. You put their picture next to a pledge amount. If you leave the donation amount up to the common man (or woman of course) you get this approximate distribution.

The breakdown of average voluntary donations results in a counterintuitive way. Sometimes like a tip at a restaurant...
Example:
Save 1,000 children ≈ $20 donation
Save 100 ≈ $20
Save 10 ≈ $25
Save 1 ≈ $50
Save 1 very specific child  ≈ $75

It's the way we are wired, or so the numbers bear out. 
It's cruel calculus. But given that we can easily be manipulated by pictures and possibly made up tales of strife, some organizations may be inclined to use this against you to benefit the other 999 hungry mouths to feed. In this case, I think that is a good idea. What do you think?

CHARGing you batteries is not the easiest thing to do some days. It gets especially difficult when you do something unusual. For instance you may have seen the MIT/Wilson Solar Grill.
This implementation is unique in the way is stores energy, which is certainly different from the way a cell phone or laptop stores power. This configuration (which has not actually been constructed to my knowledge) uses a fresnel lens to magnify and focus the rays of the sun to melt a lithium nitrate substrate. The melted lithium nitrate, due to its phase change reaction, is able to release its thermal energy for longer periods of time and at higher temperatures than other methods up to now. Heat is then redistributed through convection, which allows for outdoor cooking and heating homes. This method is referred to as "latent heat storage".

Obviously this is a unique application that requires a specific set of criteria. This could also be used to provide electric power or boil water for steam applications. 
Peltier element
Remember any time you have a change of temperature you can utilize that to create power as the heat is exchanged and returns to a neutral state. Peltier coolers use power to create heat, which in turn creates a cold side. With an application such as this, derivatives of that technology can turn a heat source, into power. If done creatively, a refrigerator too. 
Batteries, and power sources in general, are complicated things. The design may be simplistic, but usually a power supply is designed to fit an application.  Some things to consider:

Capacity (Amp Hours)
Weight 
Size (Physical Dimensions)
Discharge Rate (Time to Empty at designed load)
Charge Rate (Time to Charge, when under load and not under load)
Charge Cycles (number of charge/discharge cycles before needing to replace)
Operating temperature range (Affects charge and discharge rates. Batteries can catch fire and explode under the "right" circumstances, like being embedded in a cooking appliance like the solar grill)
Architecture of storage media: Lead-acid? NiCd? NiMH? NiZn? AgZN? NaS? Lithium ion? - and so forth.
Longevity and recyclability:
Obviously what the battery is made of has far reaching implications for the ability to recycle them. Lithium is rare, expensive, and in high demand. Lead Acid (car, marine, UPS batteries) are low cost, high weight, and readily recycled into new batteries given the proper facilities.

So, thank your local engineers for building all this stuff we take for granted all the time, and keep the innovation alive by encouraging our youngsters to... play with electricity, fire, water, light... and anything that interests them. Who knows what problem they might solve.

Topic Tuesday #42 2013/05/07 - "Disruptive Tech"

I love technology. I love history. I love science and science fiction (the inspiration for more of the former). The last few days have seen a turn in the direction of what was thought of just at the top of the year as pure science fiction. Well, when I say thought of, I mean all but those with their eyes on a gun manufacturer here in the United States. Defence Distributed, and its front man Cody Wilson, have dreamt up a cottage industry in disruption. Cody, over the last year, has designed and now succeeded in building a fully 3D printed firearm called the Liberator. It's designed as a homage to the single shot weapons that were air dropped over France during WWII. Besides that, the weapon is all plastic save the nail used as a firing pin. The plans have been released to the wild. Anyone can make one of these if they so desired.
And that is outstanding.
Don't think so? Let me explain my stance.
Freedom.
Oh... You probably want more of a platform than that. OK, look at it this way, this is a technology that cannot be stopped. It cannot be regulated to the governments liking and never will be without massive outrage. This is manufacturing in your garage. Dream it one day, make it the next. You don't need permission. You just need the know how, the raw materials and the tools to put them together. Cody made a gun. Will this gun be used to hurt someone? Almost certainly. This is a logical progression to this kind of device (3D printer). Think for a moment as I stroll down technology of years past lane. When Gutenberg and his movable type printing press came on the scene the scribes were out of a job, and it was revolution in the streets (Martin Luther ring a bell?). When the cassette tape was released and you could record onto it easily, the Recording Industry lost their minds. When the VCR came out the Motion Picture Industry went nuts. CD Burners, DVD Burners, BlueRay burners MP3, MP4, JPEG things that can make a copy of something without the originator getting their due, will always be disruptive. I recall that digital copiers were so good at color reproduction that they were used in counterfeiting operations. The Liberator is a statement and a loud extension of this phenomenon. This says, "You can't stop the future. This is the information age, and now we can make use of that information - whatever form it takes."
It is a shake up. It is a wake up call. What that call sounds like changes depending on who hears it, but really it's about freedom.

Personally, I knew this was coming, and making my own gun if just not my cup of tea. Personally, I would rather be the toy maker or make replacement parts and mockups for my own projects. But that is what most people will do. Again, take the internet as a case in point. When it was started, there was no security, no anti virus, no pictures... It was innocent, with innocent ideals. None of those early engineers considered that it would be used for terrorism, free speech, porn, dating, and social networking, or even voice and video. It proved to be disruptive. In a very short time, look how far it has come! Now, where will 3D printing go as the technology becomes less and less expensive?  In less than 10 years, I can see the personal 3D printer all over. Remember inkjet printers were very expensive when they first came on the scene; now they are practically disposable. The printer they used for the gun, was $10,000 on ebay second hand. You can get a MakerBot for considerably less. http://store.makerbot.com/ And I encourage you to go make something.

What will your imagination make next? Will regulation over these devices stifle creativity and rapid prototyping with red tape? Will it just be impossible to regulate, like desktop printing and copy machines?
What do you think?

Topic Tuesday #34 2013/03/12 - "Going Paperless"

The modern information age has presented a few problems our forebearers did not consider.
In a day (24 hour period):
If you read the newspapers you see around 30 headlines, with the attributing article.
If you then use the internet for news, you are likely to pass by over 300 news articles, with various links to other articles and source material and pictures and media and blah blah blah. 
Carry on to email and search and other various tasks; on average somewhere around 200 web pages will be encountered.
With all this, daily we encounter roughly 500,000 words. To put that in context; Leo Tulstoys's 'War & Peace' was only 460,000 words.
So we have a plethora of information at our fingertips and clouding our minds, our inboxes, and our desks.

What do we do with all this? How can we manage all this information?
The simplest way is filters. A way to index and search for what you want out of all your sources. The problem with this is that we can't index paper by much more than some basic keywords, like author, subject, date, etc. The full text remains hidden to us. Solution: Going paperless.

How do we do that?
It's a good question and one that is still very much in debate. I have seen in my daily work that most "paperless offices" actually generate MORE paper than they did before they were paperless. Doesn't make much sense, until you add the human quality of mistrust of new technology into the mix. In a few more years, the hard copies will start to become less and less. Until such time, they do have the advantage, at the end of the day, of being able to search all those papers virtually.

What does it take?
The Source Material, An imaging unit to make the source digital, A place to store the files it creates, A way to recognize the text and make it searchable and editable, Time, Effort, and An organizational plan.

You have the stuff you want to scan, that's easy to identify. Now what?
What will you use to make an image?
I have taken pictures with my phone, used a flatbed scanner, a digital copier, and sadly, hand transcription back into a document. Once you have the image then you need a program to turn the print into editable and searchable text. This is called OCR (Optical Character Recognition). Most scanners will come with one that will perform this task, like Abby Finereader. Some are better than others; you have been warned. Many also come with document management software, like PaperPort. Others will have complete package solutions that you will either love or hate, like NeatDesk. You need to be cognisant that you will be living with the imaging solutions for years to come. Many scanners outlive their computer counterparts by a decade. I recommend you select a manufacturer that has a good track record for updating drivers quickly and not abandoning products. Read the reviews. Think ahead. Think of what you would like to have the ability to do.

That said, I have some more genealogy documents to get scanned, and I'm going to buy one of these solutions and cross my fingers that the pile of papers I have, soon becomes a mass of easily indexed 1s and 0s.


What solution have you tried?

Topic Tuesday #31 2013/02/19 - "Placebo"

Once upon a time a boy who loved a girl was driven to as a question of the object of his affections. He asked, "Should I worry?". The reply was a thoughtful, "Yes.". The boy, who had not been ill in many years, began to get sick. The act of worrying weakened his immune system and made him vulnerable to the ailments he had years before. In hindsight, perhaps some questions are left better unasked, but it did serve as a valuable lesson; your thoughts have an impact on your physical body.

At the heart of this example lies an effect derived from nothing more than thought. Essentially it's a Placebo, but without the pomp and circumstance of psychic surgery, homeopathy, sugar pills, or other chicanery. The mind on it's own is powerful enough without the props to do harm, or to heal.

You don't have to believe me, or the boy, who may or may not have any resemblance to myself...
I have a little trial for you to do. It's not too difficult but it will take some concentration. Perhaps a rubber band around your wrist or something to remind you.

Tomorrow, I want you to smile. Smile for no reason. Smile for every reason. Just smile. Watch the faces of the people you encounter. See what happens to them. Note your mood though the day.
If you slip, its fine, just do it again. And again. And again. You will know you have done well if your face hurts at the end of the day. Attitude is largely a choice. You can worry yourself sick over things that have little to no bearing on things (as I may or may not have in the past) or you can choose to be optimistic and happy.

If you don't believe in placebos, you aren't alone. They do, however, work. 
Check out the actual inspiration for this post; Fear and Faith by Derren Brown -  
FIRST BROADCAST: 9pm Fri 9 November 2012 C4 DURATION: 47:36
The first part of a two-part event, Fear and Faith is an extraordinary film looking at what happens when people have the experience of fear removed through the use of a powerful new drug.

I can be described as an even keeled person. Generally calm and collected.  But beneath the smooth exterior, there is fast running water. Turbulent thoughts and tumultuous emotions, just like anyone else.  I just keep it to myself. I would like to say it is through some sort of a meditation process. A skill that can be acquired through practice. But alas, I cannot, as I have never been able to meditate. Why would I need to, some may ask. Because I sometimes have to calm myself down. You may never see it, but that is only because I have trained myself to hide it. I have found a few things that do help to ease the tension and relax.
*Exercise. Sometimes you just have to let it all out and vent your own internal frustrations with work. The effort will have the excellent effect of making you more fit, but will also tire you out, and force you to relax as you catch your breath, which happens to be the next one.
*Breathing. Just breathing. Concentrated effort on controlling your breathings will have a direct affect on your body. Taking active control over your autonomic functions gives you the psychological boost of being in control of yourself. The deep breathing will oxygenate your blood and naturally calm you as it also will increase dopamine production in the brain. As you are only focused on one thing, your body, you will naturally gain the benefits of that focus. The stress of the other items on your overwhelming agenda are on hold. You make yourself busy; engrossed with the most important thing to you, yourself.
*Just stop. Sometimes that's all you need to do to calm down. Just stop whatever you are doing and count to 10 (or higher).
*Alcohol (or other medicinal derivatives). It bears mentioning.  The best over the counter muscle relaxer available. Numerous side effects, the most critical is that of depressant. Sometimes that is what is needed. Many drugs have been prescribed for their side effects. Always use responsibly.
*Get away. Change your venue. Maybe the break room is the wrong place for your daily bread.  Walk outside. Sit in the grass. Change the air you breath and the sights you see and you may change what's in your mind and weighing on your shoulders. It doesn't take long, but could mean an enormous difference.
*Smile. The body and mind are amazingly complex in their interactions. We are also easy to deceive. So easy, that you can trick yourself. Smile, for no reason. Happiness will start to take hold as you (as my wife likes to call it) fake it, till you make it. It may sound dumb, but smile. Others will smile too.  Then you know that your simple artificial smile brings natural smiles to others, and then your smile is as real as theirs. Happiness is a choice, and everyone wants to be happy.

Lastly - Meditate. I can't-for some reason. BUT-I encourage you to try. In 2007 an associate of mine and I recorded a guided meditation session. I know that it works for some. His breathing exercise is certainly worth a try. Here it is for your pursuit of inner peace. Special thanks to CJ Sugita-Jackson and Healing Revolutions for continuing the long tradition of helping people find peace through whatever means necessary.

Topic Tuesday #27 2013/01/22 - "Dollars and $ense"

I remember buying my first car. I was excited as I saved up $1,500 over a summer and was going to buy it outright. It was going to be a hunk of junk, a clunker - but what does a 16 year old care really when the freedom of transportation is promised? I wrote the check... I felt sick to my stomach. I wanted to retch at the thought of the exchange... All my hard earned coin was going to be gone in an instant. I did it anyway. I got the car and had my measure of freedom and responsibility. You never forget your first time, and that was my first car and also my first big check.

In the world of finance, money has no value. Keeping this in mind may change your view of the world. Let me explain:
In the USA, we have dollars as our agreed upon currency standard. But what is a dollar? Two "sawbucks"?Four Quarters? Ten Dimes? Twenty Nickels? A hundred Pennies? Yes but not at all. A dollar is a promissory note. That's all. It's true worth is that of 'paper' (Though it's actually a complex blend of fibers more akin to fabric for durability-but I digress). We use them as a token of perceived value for the purposes of the exchange of goods and services. the currency itself has no intrinsic value at all. In the end, it's worth is a lie. But a convenient one.

I am a big fan of the barter system. I often wonder what I could gain from exchanging my skills with those around me. How much is my effort worth? I need a roasting hen for supper, so I could fix a sink, or repair a computer. Maybe saving your files from a crash would be worth a large pig or a cow, or painting my house in return, or maybe the paint. Hard to say. Very hard to say. Can we exist on it alone? No. Not really. What would the power company ask you in trade for a Kilowatt Hour to run said computer? What would the city ask in return for protection and clean water? It's a slippery slope to a feudal system. A liege lord and his castle keep taking care of the main functions of society while you pledge your loyalty to them. Or worse even... The company store, where you pay back your wage of effort to be always a little behind and become an indentured servant, slave labor, deep in a coal mine.


We do need regulation and standardization in a modern day. But let's review just 2 generations ago. Your grandmother could go down to the corner store and buy a loaf of bread for a nickel. She thought that was expensive. Today, the same loaf, though likely much worse for us, costs around $2.  Over say 75 years, the cost of a loaf of bread inflated. It's a simple task to understand the real value of a loaf of bread. It feeds you. It provides nourishment. It is sustenance. You can't fill your belly with money alone and expect to live long. We go with the perceived value of money. The perceived worth of a loaf of bread, a liter of water or gas or milk and so on.

It's troubling to know that the money in your pocket is almost meaningless. What happens when the men behind the curtain, that decide how much money is in circulation and what interest rates to lend more promissory notes out with, decide to print more money and circulate it wildly? The money in you hand loses value. If the regulators pull money from circulation, and artificially constraining the economy, they make the money a more scarce resource and raise it's value, it's buying power. Supply and demand - on demand. When the economy can be manipulated in such a way as the $10 you have in savings is only able to be exchanged for a quarter of what it used to, when you earned it and traded your skill and effort for it, it makes you wonder if this is the right system.

Can we go back to a fixed system? One backed by gold (The Gold Standard). Would we want to? Commodities such as gold and oil and nearly everything else of value, are traded wildly on the stock exchanges of the world. Their value fluctuates wildly.  Though the value of a dollar also fluctuates it does so at the pace of the Federal Reserve. They choose the base interest rates for borrowing, and decide how much money should be in circulation. They do so at regular intervals, so the cost of things like bread does not sway wildly out of control. It's not an enviable job. Someone will always tell you it's wrong. The sad thing is they are right in that it's always wrong for someone.

I could go on, but I want the conversation to carry it forward. Good or bad, the economy work this way in a far more efficient manner than a barter system alone could enjoy. I'm terrible at pricing my services, and will always be taken advantage of, or be made to feel like I am robbing someone if I price competitively. How many chickens is a computer rebuild worth?

In todays world we continue to push the limits of science. What tends to follow the science - is the philosophy...
Today, I want to look at what it takes to be human.

March 2011: Enter a dying man, Craig Lewis, 55, Dying from amyloidosis. Craig had 12-24 hours to live when his wife Linda okayed an experimental procedure by two innovated doctors at the Texas Heart Institute. Dr. Billy Cohn and Dr. Bud Frazier, successfully replaced his heart with a continuous flow pump. Two venturi like pump motors served as a replacement for the failed muscle. There was a catch though; Craig no longer had a pulse. EKG was flatlined. Linda Lewis said, "I listened and it was a hum, which was amazing. He didn't have a pulse." The technology passed multiple animal trials and it certainly passed this test.
I've included the short documentary on it below.

As technology changes us, as we lose those telltale markers that we are alive, how will we adapt? Our minds are a series of electrical impulses and it's a trivial jump to reason that one day we will "backup" our consciousness, and perhaps be downloaded back into a new or greatly repaired body. How will humanity deal, with immortality? Will we still be human? With no need of an afterlife, will we need religion?

SKILLS. 

The Handy Geek's Workshop: Part 0

Everyone needs someplace to tinker. Some people use their desks, some use their garages, some use the kitchen counter and table when their garages were impossible to navigate (that would be my dad, Fred Sanford). Here's where it gets problematic, my family moved from a large home (a geek haven with computers and tools around every corner and more stacked in the recesses) to a small home. I lost my 2 car man cave... Now to give an idea of scale, 2,200 sqft with 2 car garage to a 864 sqft stilt home with a carport underneath and 2 storage rooms.
The carpenter in me was screaming, "Where are we going to put the table saw? How can this work?". I was in agreement all around. It is a small house, but so far it is just me, my wife and our beautiful 1 year old daughter. It's small and easy to take care of and gives us a sense of closeness, because we are... However, where will my tablesaw go? I have an enormous 4x8 work table and lots of tools. So begins the renovations to make this smaller space functional. 
To give you a sense of the space, the house is a rectangle with the skinny end facing the street. The driveway leads from the street, underneath half of the rectangle all the way from the covered porch to the back. The other half of the rectangle is enclosed and is divided into two rooms. Each room has only 1 outlet, 1 door, 1 window, and a closet. One room has a ceiling light, and the other has none. The following posts in the Workshop Series, will involve the evolution of these spaces into; a workshop, a bathroom, and space for family and friends.
I will be adding in some sketches to illustrate the issues I have been facing. See you soon!
