I see now, thanks. So:

For medium/high caffeine consumers:
placebo -> decrease (and headache)
caffeine -> 'level 1'
Non/low caffeine consumers:
placebo-> 'level 1'
caffeine -> 'level 2'

(where level 2 > level 1).

However, I still think there might be some confusion in using a single instance for testing, esp. testing alertness. There might be a large withdrawal symptom going on in the brain that first time that makes alertness more difficult in general.
pbiggar might have some insights here, his startup (newstilt) uses Facebook logins only for this very reason.

Disadvantages?

It's hard to do- how do you verify the names? Some people will post more insightful things under their pseudonym.

Take my example; I'm quite happy to discuss my work openly if it is interesting (which it has proven in the past). My pseudonym is very open and you can find out who I am in about 2 minutes; but if I had to use my real name directly I'm not sure I would post so openly about those topics.
The results are interesting, but there's a methodological limitation the article isn't emphasizing as strongly as it should.

An illustrative analogy: Suppose you organize a group of people who often take painkillers for headaches, and a group that takes painkillers only rarely. You find that headaches of the regular painkiller-takers are no better with their painkillers than the non-painkiller-takers are without painkillers. Can you conclude from this that painkillers have no long-term effects on headaches? You can't, because the reason the first group was taking pain killers in the first place was probably because they have bad headaches, while the second group doesn't. The painkillers just bring them into parity.

The problem is the two groups the coffee study compares were not assigned their subjects randomly. They're made up of people who choose freely to drink or not drink coffee. The fact that regular coffee drinkers are no better with coffee than non-drinkers are without coffee doesn't necessarily mean that coffee has no long-term effect. It could well be that non-drinkers already have endogenously whatever benefits caffeine provides, and drinkers do not, and coffee brings them up to parity.

In other words, the current study has nothing to say on what happens to people when their long-term coffee drinking habits are changed from what they would normally prefer them to be, and so you can't infer much about the benefits or drawbacks of such changes. You could control for this by assigning people randomly two two groups, have one group drink coffee regularly for a few months while the other abstains, and then repeat the experiment performed here. The results of this modified experiment would determine whether current ad-lib drinkers should stop drinking coffee and whether current non-drinkers should start.
Indeed. I suspect the existing base of dynamo-using cyclists would scoop this up if it was compatible.
I think halo is a good smart marketing move to associate future Microsoft consumer products with halo. The 360 is by far microsoft's biggest consumer electronic success, and halo it's flagship franchise. Kids growing up now with the 360 will know it, and it's not associated with the boring windows enterprise stuff. And if you don't know halo, the names sound okay anyways.

I mean it was that or resurrect clippy.
Okay, this is not really on-topic at all. But someone has finally given me the opening to rant about the state of public restroom design :-)

I spend a lot of time working out of cafes, both for my job and when I'm working on some personal project. ~4-8 hours a day in a cafe plus a coffee every 90 minutes or so and plenty of water means I have a lot of experience with coffee shop public restrooms. And almost all of them are terribly designed.

The worst problem, common to almost all cafes, is that a place with a capacity of ~40 people or so will have two single-user gendered restrooms. By this I mean there is a label or picture on each door indicating "Male" or "Female". This is a problem for a number of reasons, including that it creates issues for trans and genderqueer people, but also that it inevitably creates situations where there is a queue for one restroom (because of a user who is taking their time, for whatever reason) while the other is empty. Of course, someone could jump out of the queue and use the empty restroom, but there's a social norm that we generally must abide that forbids this.

Another inefficiency is that faucets for washing up tend to be locked in the same single-user room as toilets. This causes backups when a person needs to use the faucet but someone else is using the toilet or vice versa. Plenty of people just pop into a single-user restroom to adjust their hair or wash their hands or whatever.

In something like 9 years of working consistently out of cafes, I've seen just two that have what I consider to be well-designed restroom facilities: the Starbucks at Main & Olympic in Santa Monica, CA, USA and Sightglass Coffee in SoMa, San Franciso, CA, USA. Each have an open, shared sink area with a glut of faucets and two to four single-user toilets behind locked doors opening out into it. I've never seen a line for the restrooms at these cafes, although I don't know if that's because of good design or because no one wants to use such weird restrooms ;-)
The funniest thing about all of these "office design" photos that I see of big companies.

"Where does the actual work get done?" Why are those photos never included.
If you bill daily, how many hours would you work per day ? 8 or 10 or 16?
This is wrong. 3.3m workers work for the minimum wage in the US. This represents 2.6% of all wage and salary workers in the economy [0]. Raising the minimum wage would simply make 2.6% of the working population better off at the expense of their employers. It's a redistribution of wealth and it has nothing to do with inflation.

You have your causation backwards. Employers being forced to pay a higher wage to 2.6% of the working force does not cause the money supply to increase. Central bank monetary policy causes the money supply to increase, creating inflation. Wages increase in order to preserve purchasing power in an inflationary economy. This is why the markets hang on the Fed's every word - the Fed has the power to change interest rates and inflation which, in turn, effects the labor market.

To address your point about deflation: QE was designed to support bank balance sheets by removing risky and opaque assets and replacing them with liquidity. Banks now have a ton of liquidity [1], but no investment-worthy projects. Thus they choose to hold their reserves with central banks, choosing a negative interest rate over the risk of lending in the economy. Wages are falling because there is less money in the economy chasing an increasing amount of goods. Therefore money is appreciating in value. Once banks resume lending out the liquidity they have been injected with we will see wages rise.

I sort of miss the time when knowing how to use Google (and knowing to use Google at all) allowed you to be instantly 10-100x smarter and more productive than everyone else.

Excluding books like novels which are written to be read from beginning to end, the easiest to skim-read books have chapter and section divisions, each with intro and concluding paragraphs. They have pictures, charts, and diagrams; they have margin notes summarizing each paragraph; they have color. Each paragraph has a topic sentence, either first or last. The book begins with contents on a single page, then a detailed contents. The written word's come a long way since scrolls were the writing medium.

I'd say the squint test does apply to the written word.

At my current job (very large corporation), I requested certain specs for my development machine, basically just lots of RAM and an SSD. I said I would be more than happy to pay for the hardware myself and they could have IT install the standard desktop.

It took 6 weeks for this request to be emailed around to various people for approval and no one (I saw the email chain) had the balls to make a decision or even give their opinion on the matter. Luckily, it finally hit someone that had both a brain and balls, whose reaction was basically "of course, give it to him immediately, the extra cost is meaningless."

The point of this is, at least to some degree, costs are not what hampers IT, you can offer to pay for something and they will still not let you have it. At mt previous job I got some very suspicious looks from a manager for bringing my own printer to work (to save 5 minutes a day walking to the printer).

I've seen it in many companies.....there's something else going on other than just budget, but I can't put my finger on it.
My own short note about this: http://rilita.com/article/eurion_constellation/
> The % of population engaged in agriculture as compared to pure consumers of agricultural produce. This is perhaps what msandford meant. The net number of agricultural workers 'producers' is rapidly declining due to higher yield 'jobs' off farm. This impacts output/acre significantly.

That has not been the case. Yields have improved in lock-step with the decrease of farmers. This is largely due to improvements in farming equipment, better hybrids, transgenic traits and other technological improvements.
I'm surprised by the number of people who don't see this as a problem.

I've worked pretty recently as the most senior developer on a team, and I saw tons of issues caused by copy/pasted code. It results in a lot of issues. Subtle bugs around `==` versus `===` in JavaScript, unecessary variables that obfuscate the code, Python that isn't Pythonic, C that was written as an example and therefore doesn't include the error handling that is constantly necessary in C (how many C examples check the return value of malloc?).

The biggest problem, I think, is that often you end up with 10 different ways to solve the same problem in the code because instead of looking at the existing code, people Googled for a solution with subtly different keywords than the previous person and found a different blogger. This kind of duplication is very hard to identify and remove, and this does cause bugs.

Of course a more experienced developer can work around these issues, but a more experienced developer also knows off the top of their head how to write the code themselves and usually does it.
Chrome, Firefox, Safari and even IE!

I have zero feeling one way or another towards javascript as I made a conscious choice not to deal with it - I write Python and Lua for a living. Just like I made a conscious choice not to deal with PHP, I care very little what happens to PHP.

You're very much the one with the "strong feelings" there, accusing "intellectual laziness" for not putting real efforts in a language which is simply not worth anyone's time - not to mention assuming that people who think the language is inferior actually use it.

As I said, it's a productivity decision. The opposite of laziness.

What is this world coming to? How can a notoriously animated prankster dramatically collapse during a presentation about gravity and go _5 whole seconds_ before standing back up? Why wasn't every student racing toward the stage with their defibrillator paddles already charged?

Kids these days with their twitters and their facebooks. Why back in my day, we _never_ socialized. Not under any circumstances! As was made terribly clear today, socializing just takes your attention away from the people around you who could collapse at any moment!

Everybody is terrible and deficient except me!
The problem is that most feedback systems (which is mostly what gamification the way it's being implemented now really is) are measuring quantitative results. Bug tracking is a job that can be hard to quantify. All you can usually measure is quantity. There is virtually no quality metric involved. You have to make sure that the goal you're trying to accomplish by adding game mechanics doesn't get lost. Too often the game mechanics end up being there for their own sake.

As others have mentioned you also have to make sure to not create unintended negative consequences. For example, maybe people earn a badge for fixing 5 bugs in 20 minutes. What happens then if people stop committing bugs so they can "build up" fixes and turn them in at once? What if people start creating bugs for themselves to fix? You can very easily create more problems for yourself if every angle is not carefully thought out - and even then you'll probably still create some problems.

Keep in mind I say all of this not as a game mechanics cynic but as someone whose entire startup is based around helping other people incorporate game mechanics (http://iactionable.com).

> We don't have the collective power to save everyon

Except we do? We have plenty of resources if they were distributed more evenly. In this particular example, other states are able to provide energy during rare events because they did not choose to go with a pure market based system. They aren’t on the verge of collapse.
I wonder if Apple would be wary of the regulatory attention that might attract.
> I always assumed they would clear the area of trees first anyways. Why let the wood rot when you can cut it down and use it?

The spaces are often so vast that chopping down the wood could delay a project by impractical lengths of time.

> I get that trees are a store of carbon and if they get submerged they will break down and release it all, but surely over the lifespan of the dam that’s significantly lower than burning coal non-stop? Wouldn’t it be equivalent to a forest fire clearing the area?

My understanding is that microbial breakdown means a lot more carbon is released as methane vs. CO2 from fires — methane being a much more potent greenhouse gas.

At various points in its history, Microsoft Windows NT and various descendants have been available on Alpha, MIPS, Itanium and PowerPC, in addition to the more widely-known 32- and 64-bit x86 versions.

The Windows Embedded version has been (is?) available for ARM, MIPS, Hitachi SH and x86.

There have been some embedded and stripped Windows boxes used for various purposes. Thin clients and storage controllers, for instance.

The Windows x86 application market hasn't been interested in the other architectures.
This because getting an installed base from x86 to another architecture is No Small Effort, both for Microsoft, and for all of the other organizations that supply or use Windows software. The FX!32 translation services were unsuccessful in encouraging folks to use Windows applications on Alpha, for instance. And if you don't get the installed base moved to your new target, you then get to own the costs of fragmentation and of running what you've brought out.

Beyond the references to iOS in the article, I'd also expect this work is in response to Google's Android and HP's WebOS, too. Android establishes the price floor, iOS aims at the revenue (and with a finger-targeted UI), and WebOS is owned by a very large Windows hardware partner.

Interesting times for the Microsoft folks.
>"Nobody" cares about x86 anymore except those married to the platform.
