Tank Chats #15 Tortoise
Published on 25 Feb 2016
Tank Museum Historian, David Fletcher is currently unavailable, so rather than make you all wait, Curator David Willey is here to present Tortoise!
The A39 Tortoise is the ultimate manifestation of the British concept of the heavily armoured, but slow, ‘Infantry’ tank.
It was built in 1947, making it a contemporary of the highly successful Centurion tank. The Tortoise proved to be too slow and unwieldy for the conditions of modern warfare and was a nightmare to transport.
The only service that the Tortoise had was when two tanks took part in trials in Germany in 1948. The Tank Museum’s Tortoise is now the only surviving example.

History of Writing – The Alphabet – Extra History
Published on Jul 29, 2017
Where did the alphabet come from? How did it develop, and why? The writing systems first developed in Sumer provided a basis for the written word, but their system of characters also inspired a shift to single phoneme systems where each letter represents a distinct sound.

“… theirs is a generation shaped by the smartphone and by the concomitant rise of social media. I call them iGen”
In The Atlantic, “Gen Xer” Jean Twenge is worried about the ways the new generation differ from their Millennial predecessors:
I’ve been researching generational differences for 25 years, starting when I was a 22-year-old doctoral student in psychology. Typically, the characteristics that come to define a generation appear gradually, and along a continuum. Beliefs and behaviors that were already rising simply continue to do so. Millennials, for instance, are a highly individualistic generation, but individualism had been increasing since the Baby Boomers turned on, tuned in, and dropped out. I had grown accustomed to line graphs of trends that looked like modest hills and valleys. Then I began studying Athena’s generation.Click to see full-size image
Around 2012, I noticed abrupt shifts in teen behaviors and emotional states. The gentle slopes of the line graphs became steep mountains and sheer cliffs, and many of the distinctive characteristics of the Millennial generation began to disappear. In all my analyses of generational data — some reaching back to the 1930s — I had never seen anything like it.
At first I presumed these might be blips, but the trends persisted, across several years and a series of national surveys. The changes weren’t just in degree, but in kind. The biggest difference between the Millennials and their predecessors was in how they viewed the world; teens today differ from the Millennials not just in their views but in how they spend their time. The experiences they have every day are radically different from those of the generation that came of age just a few years before them.
What happened in 2012 to cause such dramatic shifts in behavior? It was after the Great Recession, which officially lasted from 2007 to 2009 and had a starker effect on Millennials trying to find a place in a sputtering economy. But it was exactly the moment when the proportion of Americans who owned a smartphone surpassed 50 percent.
The more I pored over yearly surveys of teen attitudes and behaviors, and the more I talked with young people like Athena, the clearer it became that theirs is a generation shaped by the smartphone and by the concomitant rise of social media. I call them iGen. Born between 1995 and 2012, members of this generation are growing up with smartphones, have an Instagram account before they start high school, and do not remember a time before the internet. The Millennials grew up with the web as well, but it wasn’t ever-present in their lives, at hand at all times, day and night. iGen’s oldest members were early adolescents when the iPhone was introduced, in 2007, and high-school students when the iPad entered the scene, in 2010. A 2017 survey of more than 5,000 American teens found that three out of four owned an iPhone.
The advent of the smartphone and its cousin the tablet was followed quickly by hand-wringing about the deleterious effects of “screen time.” But the impact of these devices has not been fully appreciated, and goes far beyond the usual concerns about curtailed attention spans. The arrival of the smartphone has radically changed every aspect of teenagers’ lives, from the nature of their social interactions to their mental health. These changes have affected young people in every corner of the nation and in every type of household. The trends appear among teens poor and rich; of every ethnic background; in cities, suburbs, and small towns. Where there are cell towers, there are teens living their lives on their smartphone.
It could be that the widespread use of available technology to “virtualize” adolescence is at least to a degree a reaction to helicopter parenting.

QotD: Improved quality of life doesn’t always show up in GDP figures
We economists marvel, too, but we also wonder how free apps fit into GDP. They do have their long-run downside, as we forget how to read maps and plot routes ourselves. (Anybody out there remember how to work a slide rule? No? That’s not a loss for computation but it does mean lower average numeracy.) But in the short run they save billions of hours in wrong turns not taken and trillions of cells of stomach lining no longer eaten up by travel anxiety. Not to mention their entertainment value.
But hardly any of that very big upside shows up in GDP. In one respect, in fact, GDP goes down. I used to buy maps, including travel atlases. I’m unlikely to do that anymore. Maps purchased by consumers are a “final good or service” and thus do enter into GDP. Maps I interact with online but don’t pay for aren’t GDP. So well-being has gone up — a lot — as a result of Google Maps. But GDP may well have gone down.
In fact, apps do produce some GDP. Google sustains itself in part by selling ads, including to retailers and restaurants looking to pay for prominent mention on its map display. Its ad revenue is an intermediate input into GDP. Many of the entities buying Google ads are in the business of selling “final goods or services” and if they’re money-making, the prices of their goods have to cover the cost of their ads. So by that circuitous route the “value” of the apps does end up in GDP.
But what’s the relationship between what advertisers pay for my eyeballs and the value of the app to me? The two are not completely unrelated. The more I use the app the more I’m likely to buy the advertised products, presumably. But in practice, the probability of my buying is pretty small while my benefit from the app is pretty big. How strange that miracle apps can change our lives but not our GDP.

Ontario adopts voluntary self-surveillance app from CARROT Insights
I often joke about how inexpensive it appears to be to “influence” politicians, but it’s only fair to point out that the voters those easily influenced politicians represent are even more easy to influence:
Ontario announced earlier this month that it will become the fourth Canadian government to fund a behavioral modification application that rewards users for making “good choices” in regards to health, finance, and the environment. The Carrot Rewards smartphone app, which will receive $1.5 million from the Ontario government, credits users’ accounts with points toward the reward program of their choice in exchange for reaching step goals, taking quizzes and surveys, and engaging in government-approved messages.
The app, funded by the Canadian federal government and developed by Toronto-based company CARROT Insights in 2015, is sponsored by a number of companies offering reward points for their services as an incentive to “learn” how to improve wellness and budget finances. According to CARROT Insights, “All offers are designed by sources you can trust like the BC Ministry of Health, Newfoundland and Labrador Government, the Heart and Stroke Foundation, the Canadian Diabetes Association, and YMCA.” Users can choose to receive rewards for companies including SCENE, Aeroplan, Petro-Canada, or More Rewards, a loyalty program that partners with other businesses.
It’ll be interesting if they share the uptake of this new smartphone app … just how many of us are willing to let the government track just about all of our actions in exchange for “rewards”.
In order to use the app, users are giving Carrot Insights and the federal government permission to “access and collect information from your mobile device, including but not limited to, geo-location data, accelerometer/gyroscope data, your mobile device’s camera, microphone, contacts, calendar and Bluetooth connectivity in order to operate additional functionalities of the Services.”
Founder and CEO of CARROT Insights Andreas Souvaliotis launched the app in 2015 “with a focus on health but the company and its partner governments quickly realized it was effective at modifying behavior in other areas as well,” according to CTV News.
106 – How to Build a French Cleat Storage System
Published on 17 Nov 2009
Original post on our site with additional information, plans, questions & comments:
http://www.thewoodwhisperer.com/videos/french-cleat-storage-system/A French cleat is as ingenious as it is simple. It involves securing a strip of wood with a 45 degree bevel to the wall, and then securing an opposing beveled strip on the back of a cabinet or anything you want to hang. Its incredibly strong and versatile. Its a great way to hang cabinetry and as you’ll see in this video, it can be used to make an awesome modular wall storage unit.

Patents, Prizes, and Subsidies
Published on 17 May 2016
Growth on the cutting edge is all about the creation of new ideas.
So, we want institutions that incentivize such creation. How do we do this? The answer is somewhat tricky.
The first goal for good ideas is for them to spread as freely as possible. The further the reach, the greater the gains. The problem is, if just anyone can use ideas, then why would we ever pay for them? And without the right incentives, why would innovators create new ideas at all?
Imagine yourself as the creator of a new drug. Typically, it costs about a billion dollars to do this, not counting the time and effort needed to get the drug FDA-approved.
Now, if there were no protections in place, then theoretically, once the formula’s known, everyone could just copy the make-up of your new drug. See, the thing about pharmaceuticals is, once the formula’s known, production is relatively cheap. Given that, let’s assume imitations start flooding the market.
Predictably, the price of your new drug will plummet.
Once prices hit rock-bottom, you’ll have no way to recoup the $1 billion you spent on R&D.
Given that kind of result, we reckon you probably won’t want to develop more good ideas.
The US founding fathers anticipated this problem. Knowing that innovators needed incentives to have good ideas, the founders wrote a protection mechanism into the Constitution.
They gave Congress the ability to grant exclusive rights to inventors — rights to use and sell their inventions, for a limited period of time. This exclusive right, is what we call a patent. Patents grant inventors a temporary monopoly over the use and sale of their intellectual property.
Now, as nice as this is, patents are a thorny subject.
For one, how long should patents last? Also, how much innovation is considered enough to merit a patent grant? Not to mention, are patents the only way to reward good ideas?
The answer is no.
There are two more incentive options here: prizes, and subsidies.
Let’s start with subsidies. University and research subsidies are particularly effective in the basic sciences. Since innovations in this space are rather abstract, subsidies incentivize research without requiring the applications of the research to be explicitly named. The problem is, when we’re incentivizing just research, then researchers might pick directions that are interesting, but not particularly useful.
This is why the third incentive option — prizes — exists.
Prizes reward the output of solving a certain problem. Another plus, is that prizes leave solutions unspecified. They provide a problem to work on, but give quite a lot of leeway as to how the problem is solved.
Now, knowing the complexity inherent in patents, you might think that prizes and subsidies are good enough alternatives. But none of these incentives for ideas, are inherently better than any of the others. Patents, prizes, and subsidies all involve their own tradeoffs and questions.
For example, who decides what gets subsidized? Who decides which goals merit a prize?
It’s hard to determine what mix of institutions, will best incentivize the production of good ideas. Patents, prizes, and subsidies all navigate these conflicting goals, in their own way.
And yes, all this talk of incentives and conflicting goals and tradeoffs might be like walking a tightrope. But, it’s a tightrope we can’t opt out of. Certainly not if we want the economy to keep growing.
In our next release, you’ll watch a TED talk from a certain economist that elaborates further on ideas. And then, we’ll wrap up this course segment with the Idea Equation. Stay tuned!
