As the trend towards urbanisation (rural flight) continues worldwide, and as population continues to grow, the rent isn't going to get any cheaper in the decades to come, anywhere.

Even imagining that 3D printing techniques can significantly cut down the cost of new construction (as is starting to happen in China), land scarcity will be the overriding factor. Save building cities on the ocean, we can't escape it.

If DPRK has the capacity to pull this sort of hacking feat on demand, it begs the question: why aren't they doing it around the clock, to hurt their enemies that they seem to hate so much? It's just not very realistic to think that DPRK has this super secret hacker army (but not so secret that we haven't heard of it in the media) that can hack any large corporation (but can't cover its own tracks). If they did, we would see it action all year long.

This hack sounds like the work of a large, professional, well-funded organization that only uses its capabilities in a very targeted, parsimonious manner. But what would be the motive for the US govt to hack Sony and then accuse DPRK? Distract the public from the CIA torture report? Something else?

Examples are abundant and easy to find. Here is an example of sexism and discrimination coming from Paul Graham. Highly relevant to this discussion about female founders at YC.

http://www.thewire.com/technology/2013/12/paul-graham-revive...

Women are getting harassed and discriminated against in Silicon Valley tech companies all the time. Take this example from Github: http://www.theverge.com/2014/3/19/5526574/github-sexism-scan...

This needs to stop. And comments like yours are just one more example of how deeply rooted sexism is on this site.

YC and PG have a history of sexism and actively discriminating against women (see http://www.thewire.com/technology/2013/12/paul-graham-revive...).

For this reason, yes, it is important to mention that Alex is a woman, so as to make potential female women less scared of approaching YC. In a perfect world it wouldn't be necessary, but because the climate in the industry is one of harassment against every woman, it is necessary to point out successful examples of females in tech and in YC.

Are you denying that women are being heavily discriminated against in developed countries, like Norway or the Netherlands?

Technology and entrepreneurship are very attractive in terms of social prestige and salary, therefore if women weren't being harassed and discouraged by men from entering these fields, you would be seeing roughly 50% of female engineers and entrepreneurs.

Maybe even somewhat more, since women tend to be smarter than men on average (which is why girls tend to succeed better in school than boys).

Edit: here come the downvotes from males in denial. If you feel the need to downvote me because I am stating a simple fact, you are part of the problem.

"Biped" is only found in the context of science (evolutionary biology) or technology (robotics).

Indeed, that had escaped me. It makes the case stronger then.

Many variables share this exact graph shape over the 1960-2000 period, without having anything to do with crime. It's not a particularly characteristic shape. This seems to be a textbook example of "correlation does not imply causation".

If there was causation (due to the neurological effects of long-term lead exposure during childhood years), then you would observe delayed correlation (at a 20 year scale), not simultaneous correlation.

Any risk estimate makes implicit assumptions, so they are conditional probabilities rather than absolute probabilities. It is assumed that Amazon engineers mean to prefix these data loss numbers with "under normal operation of our services".

Definitely, exceptional and unpredictable incidents make the absolute risk higher. But in the absence of historical data about the rate of occurrence of such events, it is impossible to make a reliable assessment of absolute risk. Not only is it impossible to assign a realistic probability to events that you know can happen (eg. catastrophic bug), but many of the possible incidents are events you are not even aware can happen (eg. are you going to factor the risk of a meteoric crash destroying your data centers?).

Any planet harboring intelligent life would likely be several hundreds (like this one) if not thousands or millions of light years away, making any contact impossible at human scale. Even with this relatively close example of a possibly habitable planet, communications would take 1000 years to go back and forth.

As for actual contact... many earth civilizations would rise and fall before a spaceship going at even 2% of the speed of light could reach such a planet.

As far as I can tell it's now a network of content sites (Tumblr, Flickr, Yahoo Finance, Yahoo Weather, a long site of Yahoo {{content_type}} sites, etc), monetized through targeted advertising.

Their demographics are typically older than average, and therefore easily monetizable through display ads. They seem to be doing quite well.

In the absence of a direct way of arbitraging between YHOO, Alibaba and Yahoo Japan, is it not surprising that the respective valuations of these entities will become disconnected.

The market value of a company does not represent its actual worth. Yahoo is not worth negative 13B.

This is a great variant. I wonder if it would be possible to conceive a chemistry version that can could potentially teach people about atomic bonding?

A bit easy though, I had no trouble beating it after a couple tries.

I believe these laws target human cloning experimentation, rather than cloning as "twin manufacturing". The fact is, we don't know how to make fully viable clones yet (see the fate of our most advanced animal experiments for reference).

As such, it would be unethical to attempt to create a possibly failed human clone.

I wish more abandoned projects were open-sourced instead of merely shut down.

Like Google Wave, which became Apache Wave after Google lost interest in the product...

The question of whether time is in fact directional is far from being closed, at least for quantum physicists. In fact, one of the physicists cited in the article is known for proposing a time-symmetric formulation of Quantum Mechanics [1].

It's a new success for Deep Learning. It seems to be actually 99.8% accuracy according to their paper: http://arxiv.org/abs/1312.6082

That's one order of magnitude higher.
