Ask Slashdot: Dealing With Electronics-Induced Inattentiveness?

Re:Don't be passive, DO something (312 comments)

I stumbled upon a solution while taking an online course... watching the lecture at 2x speed helped me focus.

It turns out that watching a lecture in real time allows me to get bored and I end up doing a context switch. Perhaps distraction isn't the problem, but in this age, we've learned to process information more quickly.

Scott Adams's Plan For Building Giant Energy-Generating Pyramids

(sorry, lost formatting)

Let's math:

Assuming that the miles high pyramid uses free sun power to melt sand and we only need PV to power lifting the glass blocks

The great pyramid of giza is 455' tall and has 10^12 joules of potential energy (http://what-if.xkcd.com/95/)
A 2 mile high pyramid with the same dimensions is about 12x taller
If you scale up the pyramid by 12, that's 12^4x more energy (http://www.physicsforums.com/showthread.php?t=428636)
12^4*10^12 joules=2e16 joules = 5e9 kWh
Wholesale price of electricity is 5 cents per kWh
5e9 kWh * .05 dollars/kWh = 250,000,000 dollars

This could easily triple depending on motor losses and other energy costs. So you could make your giant pyramid with "free" energy or you could sell the energy on the open market for almost a billion dollars

Why You Shouldn't Use Spreadsheets For Important Work

If the inability to code review spreadsheets was a real issue, it wouldn't be too hard to convert spreadsheet functions into a functional language. For non-programmers, a spreadsheet lowers the barrier to entry. This allows people to do something useful and productive who couldn't do so otherwise. That's a good thing.

Measles Virus Puts Woman's Cancer Into Remission

Viruses without common antibodies... (74 comments)

It's interesting that the treatment is hypothesized to have failed for people who already had measles antibodies. Perhaps the "extinct" viruses the CDC keeps around might be good for engineering future treatments.

Land Rover Demos "Transparent Hood"

It's no coincidence that the hood was black (172 comments)

With a light colored hood, the heads up display during the day would be washed out.

I imagine that cars with this technology would benefit from a matte black hood, making future cars look like modders with carbon fiber hoods. Next, we'll see some technology that requires a huge spoiler :)

FWD.us Wants More H-1B Visas, But 50% Go To Offshore Firms

Re:Isn't the upshot the same? (325 comments)

+5 insightful? 2:1 or 3:1 ratio of workers to roles? While it would be fun to feed into the frenzy going on in this message board, that means for every job, there are 1 or 2 unemployed people... 50-66% unemployment And before you say that they're just underemployed, I've interviewed hundreds of candidates and the vast majority can't do simple aspects of the job (in my case, it was to write code). So, no, you're dead wrong and the people who modded you just have some sort of agenda or lack critical thinking

Austin Has Highest Salaries For Tech Workers, After Factoring In Cost of Living

Exactly, let's factor in the cost of my time sitting in traffic. If you assume 1 extra hour round trip at 1.5x pay, \$100k turns in to \$84k for the time you're actually at work and \$16k for sitting in traffic. Until self driving cars come along, you'll be staring at the truck in front of you for a non-trivial portion of your life

Is Traffic Congestion Growing Three Times As Fast As Economy?

GDP growth != more jobs created (187 comments)

The great recession of 2009 became the justification of many companies to lay off workers despite healthy revenue and increasing profits. While this may contribute to the GDP, it doesn't do much for employment.

DARPA Funds Research Into a Network-Based Interpretation of Dreams

What is this really? (54 comments)

This study doesn't have to do with dreams so much as word association. If you think that multiple cultures having similar dream interpretation reinforces anything about what the dreams actually mean, you'd be a bit misled

Microsoft's New Smart Bra Could Stop You From Over Eating

You're missing the point of the GP post. Yes, if you eat more calories, you're going to get fatter than if you didn't. But his point is this: why are some people constantly hungry when they eat the same amount of food that fills another person? What in the environment is changing that is causing various groups of research animals (across different species) to increase their weight over the years? According to this paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3081766/, the odds of this trend happening by chance is 1.2 × 10^7.

Should the US Copy Switzerland and Consider a 'Maximum Wage' Ratio?

Let's say I'm a CEO. Anyone below the 20:1 salary ratio gets "outsourced" to a different company sharing the same parent company.

Ask Slashdot: Is Tech Talent More Important Than Skill?

What's more important - velocity or acceleration? (277 comments)

It depends on how much talent versus how much skill. You COULD just calculate the area under the curve to get total value...

A Tale of Two Tests: Why Energy Star LED Light Bulbs Are a Rare Breed
