Evbn··on Ask HN: Are you planning on getting Google Glass?
You shouldn't make predictions based on an extreme minority opinion. Even RMS knows how to separate morality from probability.
Evbn··on Chinese Way of Doing Business: In Cash We Trust
That seems very easy to detect (with police on foot, like US underage alcohol stings) and send people to gulag for.

Laundry? US bills are made of cloth.

Weird that a tightly controlled nation like China hasn't killed the fen yet.
Evbn··on Winky Google Glass APP - hacked into Google glass and enabled winking control
Or a device you do control streaming to servers to you do control. There isn't a little MiniTruth man checking every byte going through the camera.

Because stupid linkbait survey.

Comfort food is comforting because it is nostalgic.
Evbn··on 17% of UK Adults Believe Google Has Their Best Interests at Heart
Their stock holders may have customers interests at heart. That is how a good business works.
Evbn··on 17% of UK Adults Believe Google Has Their Best Interests at Heart
That is a rather vague question. Google has 50K hearts.
Evbn··on The Case for Using Mad Lib Sign Up Forms
That's not what a mad lib is.

That is how every real estate / rental,contract works in the real world.

Quite the Freudian slip for Mr Church.

That is a big IF.

Evbn··on How to eat healthily on £1 a day
At some point the assumption of sanity breaks down, in this lifestyle.
Evbn··on How to eat healthily on £1 a day
In the US, public transport is at least $20 per week, for a minimum commute.

x2 for 2 wage earners.

$1/day(!) per person is another $5 each.

Replacing worn out clothes adds a touch.

Water/sewer is ~$5/wk/person for very light use. Energy for light/heat/cooking is similar.

That is bare minimum for survival.

Income is a poor approximation of wealth, indeed.

Fat people have lots of fat. Muscle and bone amd cardiovascula health and brain mylenation are another matter.
Evbn··on How to eat healthily on £1 a day
I obsess over price per ounce of my food while I am in the store. (Though it gets harder as I age and my brain weakens, and as prices and sizes get intentionally harder to compare)

Even still, I myself that groceries I eat are super cheap compare to food I throw away and restaurant meals. (And I avoid packaged meals and name brand cereal, which are near restaurant priced)

Every now and then I remember that the vast majority of people don't or can't think about food costs, and shudder. Paying $2 for a bottle of water with a scoop of sugar poured in. $5 for a box of Kellogs instead of $3 for generic. $4 for the frozen brocolli with fake cheese sprinkled top instead of $2 for plain. Etc

Evbn··on A Skeptic’s Guide to the Mind
Many biases can be adjusted for. It is hard, though.
Evbn··on Daniel Dennett, Author of ‘Intuition Pumps and Other Tools for Thinking’
Leading thought is that we are neural networks with neurotransmitter "macros", not common computers. Of course computers can simulate this model.
Evbn··on Get that job at Facebook (2012)
That is an example of a theoretical solution that may be overkill in practice, especially if you are stuck in JS. Unless you send window positions back to the server for analysis.

And can you code an AABB tree on a whiteboard? :-)

One could try placing the new window at (100x, 200y) for integer x,y, and check for intersection each time with all the existing windows. 3600 overlap tests in the worst case, but you get huge benefits in practice by hinting the location of the last new window.

Optimize a bit by sorting lists of windows by x and y, so you can binary search for the few candidates to overlap test, and you are down to about 1000 window checks. You miss some cases if windows are very maliciously aligned off grid, but you can mitigate that by using a slightly finer grid.

Or test the 8 neighbors (edges and corners) of each existing window (if any), as it is nearly impossible for available space to be not one of those positions.

(You can compute the next window position after the previous window creation or move, so there is no latency when rendering a new window.)

It may be free, but it isn't open to all. They have an admissions gate, aka "picking winners".

Right, it is artificial social barriers set up to exclude the many for the benefit of the few, like the "Ivy League" imprimatur or being in a "good family".
Evbn··on Peter Norvig and eight others are Hacker School residents
Norvig is a great scientist and teacher, but you don't need this. In Residence concept is a throwback to the bad old days of exclusionary education. We have the Internet and great books (Norvig wrote one) and MOOCs the future is egalitarian.
Evbn··on Pirates playing a game dev simulator complain about piracy
Taxes are very rarely considered good. Spending projects are often good, and they balance out or exceed the pain of taxes (we hope)

Plus ~5% for the income deducting effect of donating 25% of income to a charitable nonprofit not under their control.

Obama didn't say his tax rate was too high, so that isn't relevant.

Do you get high population that way? Because that solution is highly effective for low population special taxing districts like Chevy Chase Maryland

And an easy way to prevent massive revenue from unbalancing the game.

Remember that simcity is a socialist fantasy world: all development is directly purchased by central government. In the real world, zoning doesn't cost money, and stadiums are sometimes owner financed.
