Comment Re:Good. (Score 1) 421

"the Fed is [...] supressing interest rates and [...] punishing savers [...] who shun the stock markets"

Could that be because they want to motivate banks, companies and individuals to invest in stock markets instead of putting their money in term accounts, to create "more exits" that TFA is talking about?

That is not to say I disagree with most of what you say, but it's just to point out to some reasons that drive these decisions (although we may think they're dysfunctional).

Comment Pay what you want? (Score 2) 128

When I read your post I realized that I would like to pay something between your suggested $1 and $10. And each time you give that choice to one of your customers they will pay less than what they're willing to, not more. If you're able to offer a "pay what you want" option (but require to pay at least $0.01) you can rest assured that many of your customers will go higher than the "pre-set" options you might offer them. Not a complete solution but at least my 2 cents.

Comment Not that useful. (Score 1) 290

Gamification is an example of extrinsic motivation - the kind that gives you a substitute for the joy of work itself. It can be effective (in a similar way that money motivates people to do all kinds of jobs they hate) but it can be hardly a substitute for "intrinsic motivation" where you aim at making the actual work more interesting - in your example by making the training interesting and relevant to people, by avoiding all kinds of stress by submitting work in time, by giving people a greater variety of tasks, more responsibility - simply a more interesting job, not a more interesting badge.
The outcome may seem the same... until you remove the rewards - look for reference [11] in the Wikipedia entry. That's why intrinsically motivated people keep doing their jobs even though they are extremely badly paid (in my country, that would include e.g. pastors, teachers and even doctors).
In short - if you need "gamification" then in the first place you need to admit that the gamified job sucks.

Comment Re:But can the simulator tell me ... (Score 1) 143

Playing well with others is not easy to test but it's possible - often tested in assessment centers, if you heard about exercises like "stranded on a deserted island" or "build a Lego bridge", plus being observed throughout a whole day of testing.

One question that no testing can answer, at least to my knowledge, is "is the candidate lazy"? :o)

Comment Holding inventory is costly (Score 1) 327

Holding inventory has some costs that are not so obvious:

* Producing millions of units before you get the revenue from them costs a lot of money. Money is not free - it either comes with interest, or lost opportunities.
* Paying for warehousing capacity that you only use when you launch new products (whether it's central warehouses, retail stores, or partners' facilities).
* Production capacity and speed is limited. Not every supplier would be excited to get a contract for iPhone that uses tons of capacity over 3 months and leaves their production lines empty for the rest of the year.

Focusing on inventory minimization is called Just in Time, only it's most often used in industries other than electronics: http://en.wikipedia.org/wiki/Just_in_time_(business)

Education

Submission + - Games for basic learning?

kubajz writes: My kids (grades 2 & 4) need to spend a lot of time practicing basic math, touch-typing and English as a second language (and Czech, but I don't expect Slashdot help here).
They also love to play computer games. I generally dislike cheap "edutainment software", but there are some cool games I stumbled upon — like The Typing of the Dead for touch-typing, Bidmas Blaster for math or JoyTunes for playing the recorder.
My preference is Windows and free or cheap, but others might be interested in other OSes and more expensive options. Feel free to include any modern-day "SimCity"s, but please refrain from anything equally or more serious than the Khan Academy.
So, what bits of software do fellow Slashdotters use for areas like their offspring's math practice?

Submission + - Device Scavenges Ambient Electromagnetic Energy (gizmag.com)

Zothecula writes: As you sit there reading this story you're surrounded by electromagnetic energy transmitted from sources such as radio and television transmitters, mobile phone networks and satellite communications systems. Researchers from the Georgia Institute of Technology have created a device that is able to scavenge this ambient energy so it can be used to power small electronic devices such as networks of wireless sensors, microprocessors and communications chips.

Submission + - Google Targets Psudonyms For Google+ Account Cull (thinq.co.uk)

An anonymous reader writes: Google may still be throttling sign-ups to its social networking service Google+, but it's also thinning out the ranks of its current members as it struggles to meet demand. Businesses were the first to go, and they've now been joined by those who value their privacy or have other reasons to use a pseudonym.

Submission + - Novel Drive Wheel System Based on Spinning Sphere (ieee.org)

An anonymous reader writes: A Bradley University student has built a mobile robot that uses a hemispherical omnidirectional gimbaled drive wheel, or HOG drive wheel [http://spectrum.ieee.org/automaton/robotics/diy/youve-never-seen-a-drive-system-like-this-before]. It consists of a black rubber hemisphere that rotates like a spinning top, with servos that can tilt it left and right and forwards and backwards. The HOG system delivers an amount of torque directly proportional to the tilt of the hemisphere, allowing the robot to move incredibly fast nearly instantaneously.
