>> How much extra energy is needed to keep the lead-lithium melted

You misunderstand. The energy from the fusion is taken up by the molten lead -- which is then used in a heat exchanger, like the present fission reactors etc.

(The steam pistons also get their energy from the created heat. It seems unlikely that accelerating all those steam pistons won't be the major energy cost in the system, but sure -- pumping lead is hardly easy. But five times more than the pistons?)

So the thing missing from an experimental power plant is a heat exchanger, like fission etc power plants. (And sure, lead is less fun than water!)

I assume THAT is what you missed and assumed was a major problem?

From what I've read, the proposed experimental system will (if it works) not be built to last for long, it is experimental. But again -- the energy system needed for this to be an experimental power plant is very similar to most other power plants that work by heating a medium. Work has been done on much worse than lead (see liquid sodium!).

(About not being built to last: There are lots of moving parts, but those should probably not be a show stopper; boat engine pistons work for quite a while.)
Just to clarify, the "constant growth" refers to exponential growth, compounded at a constant rate, like a bank account growing at 2% per year. Its not linear growth.
Wait. There's a huge gulf between Bolas' viewer (http://projects.ict.usc.edu/mxr/diy/fov2go-viewer/) and the Oculus Rift. One's a cute little DIY project. The other is a substantial piece of technology -- one that seems to build more on virtual reality helmet concepts from the 1980s and 1990s than on Bolas' project. Bolas might have inspired them to go down this path and explore VR hardware, but isn't that what teachers are supposed to do?

A team can absorb the natural peaks and lulls that accompany high performance far better than an individual can.

If you need everybody to be operating at 100% week on week in order to hit your deliverables then you have over promised and introduced an incredible amount of risk into your projects.

As a manager, if you care about the productivity and general well being of your team then you will be promising a max of around 70% team effort. Managing the expectations of other teams and departments is part of being a decent manager.

Spend two weeks sharpening the ax and then another cutting down the tree? No, the average company would rather you spend six, or even twelve, weeks chopping away with your blunt ax.
I don't think there's any question about dominance, rather, it's about complacency.

If in the coming years Russia takes Ukraine, and or other countries like Latvia or Moldova, it'll be due to the West being complacent. Putin - or any dictator - 'winning' the first four rounds due to other nations having an attitude of not giving a shit, would match up with what typically has happened throughout history.

Back in the 90s, I had a friend who was an instructor for Sun Certification classes. He told us of a kid who, when he turned 18, was given his college savings by his parents to do with as he pleased. He chose to spend the ~200K getting every Sun cert available.

He then became a consultant at 21 making about $500K a year, at least for a few years. Don't know what happened to him after those certs became useless, but I hope he converted somehow.

The intent (on top of just basic "get our name out there" promotion) is to get devices into the hands of developers to make it more likely they will develop software for it. The sort of ultimate example of this (though obviously not as successful as hoped) is RIM basically giving PlayBooks away like candy to developers when it shipped. The thought being if developers have this device, they might be inspired to write software for it; or if developers have our specific Android device, they may give it special attention as a development/test target, which helps us.

In the case of Google IO though the freebies were such a good deal that many non-developers who are constantly looking to resell hot gadgets (the slickdeal-reading types who camp out at walmart before a new console release and try to buy 5 units so they can "flip" them on ebay) tend to come out of the woodwork when IO rolls around. This seems to contribute to the massive amount of registration interest Google IO gets relative to the size of the event (combined with the fact that all the talks are published in video form right after the conference) and the anecdotal rapid drop-off in attendees present at the conference from day to day.

Precisely.

The author defines language as a mapper from input to output, which is necessary but not sufficient. Its L_silly (written in Ruby) is not a language since it uses "eval" which depends on the entirety of Ruby.
I agree, although I think "top of the funnel" issues are important too. I've seen too many examples of poor interviewing process, too many bad hires made, and too many good hires passed over to not put most of the onus on the middle of the funnel. Most interviewers are just not good at understanding the fragility of the process, or in having sufficient empathy to understand the difficulty of getting good data on a candidate. The worst part is that because bad hires tend to be let go eventually and passed over good client don't even register on the radar the whole system is heavily geared toward inadvertent confirmation bias.
> Also, does anyone know how security updates are handled? Would suck to be stuck on an unpatched beta while gotofail/heartbleed/Security Update 2014-002 type bugs are in the wild.

This is a new program, so there may be a change in how quickly seeds are distributed, but in the Mac Developer Program, typically the appropriate security update showed up in the next pre-release seed: it could either be the same day if the stars align, or sometimes up to two weeks.

Lately, they've been pushing out pre-release seeds every couple of days, though. Nevertheless, running pre-release software is definitely "at your own risk."

The author misses the point that Kolmogorov Complexity isn't meant to be used as a practical measurement, but is just a theoretical way to think about information. There is no way to measure a string's "Kolmogorov Units", but you can just generally agree that "abababababababababababababababababababab" is less complex than "ababaaabbabaabaababbbabaababbbaaababbbba".

If you really wanted a practical standard measure, the language would have to be simple Turing machine instructions, so that the language implementation isn't more optimized for expressing certain things (which is the problem discussed in the post).

The coast is about the only part of Maine that is inhabited. That particular dark green area is largely remote, quite harsh, and has very little infrastructure. North and west of there is the tiny sliver of inhabited Quebec, then go much further beyond and you're in some of the harshest, most remote land in North America.

If you're interested in what the area looks like, check out the Trans-Taiga Road as well as the (less remote) James Bay Road.
That bias with a fixed L is present, but you already mentioned the answer in your article: the difference is bounded.

So much FUD in this thread. Nobody actually has cancer from working with nanoparticles. Researchers have been making carbon nanotubes for years and none of them have cancer.
I think the post is correct that we can define a language which makes the algorithmic complexity of a given string zero. This doesn't contradict the invariance theorem, as far as I can tell. The constant c in the invariance theorem

|K_1(s) - K_2(s)| <= c

will be at least the complexity of the special string in the other language, but it still exists.

The comments on this threat about the OP are cruel, so cruel, so critical, I mean, so negative! :-)!

I mean; I mean; I mean; just what is the problem with raping, pillaging, exploiting, mining, filtering, drilling and blasting, harvesting, clear cutting, etc. each employee's family, friends, fellow school alumni, neighbors, SO, social networks, etc.?

Somehow most of the posts here seem not really to understand: The OP is just writing an article to get publicity for himself, his company, and First Round. What could be wrong with that?

With "right under your nose", eyes, chin, rear end, feet, etc., he is just spinning a catchy title for a catchy story that can get 'into' and get all fired up about, at least until think again in the morning. I mean, what's wrong with that? Since it's 'media', you expected something else?

In particular, I just can't overlook the leading comment by
tptacek who threw 10,000 razor blades, 1000 sharp knives, and a full 90 second blast from the main gun of an A-10 right at the OP. Of course all the tptacek remarks were rock solid, but why beat up on some childish writing just trying to get some attention?

Sure, if anyone actually followed the ideas in the OP, then there might be some little consequences such as wrecking their company by some outrageous, egregious managerial incompetence, but isn't that a small price to pay for the
thinking in the OP? I mean, where else did you get such ideas?

Besides, after the OP, wouldn't you really like to have First Round helping your company with your recruiting?

I mean, how much do you expect for free? Or, ideas are free. Ideas that won't wreck your company, $1.00. Good ideas are $100. Ideas that are actually useful -- priceless!

I think he means the decision to do YC shouldn't be driven primarily by the benefit of the cash investment. Yes, the company should be driven to make money, but the transaction between the company and YC should be driven by the overall impact (on the company being able to make money), not on the investment amount itself.

No one (I think) is suggesting that you start a business without the intention to make money.
So, what if some omnipotent trickster/adversary/god designed a deterministic universe specifically to fool you into thinking you have free will?

These terms are standard for all the Apple developer programs. In practice, they have been largely unenforced due to the definition they use for Confidential Information:

> Information that otherwise would be deemed Confidential Information but (a) is generally and legitimately available to the public through no fault or breach of yours, (b) is generally made available to the public by Apple, (c) is independently developed by you without the use of any Confidential Information, (d) was rightfully obtained from a third party who had the right to transfer or disclose it to you without limitation, or (e) any third party software and/or documentation provided to you by Apple and accompanied by licensing terms that do not impose confidentiality obligations on the use or disclosure of such software and/or documentation will not be considered Confidential Information under this Agreement.

Clause (a) generally protects anything interesting to talk about, because all the rumor mill sites have full run-downs within a few hours of release. Very rare and circumstantial cases aside[1], publishing the contents of pre-release software on such sites has been considered well within legitimate public interest.

[1]: The most recent case I can think of where Apple was able to go after a rumor mill site for divulging trade secrets (and, more importantly, have it stick) was the when they got Think Secret to shut down in a settlement related to its leaking of the original Mac mini.

I'm doing my best, and doing pretty well (making 6 figures as a college sophomore), so my regrets are more social/intellectual than monetary. Though sometimes I wonder if YC would have accepted me if I had advertised my Ivy League stamps of approval (acceptance letters)...

That's the thing. TalentBin is not for engineers. It's for HR and CEOs and recruiters. They don't care if it's scummy.

On a side note, the line about lowballing and refusing decent equity resonates with me.
People (including me) keep reinventing this concept every few years thinking they are first to market or doing it slightly differently but "right". They all fail. History certainly repeats in building social referral websites for recruiting. Someone should build a list of failed sites that tried do this, hopefully saving future entrepreneurs time and money.

The core of the problem is that it's socially stinky to exploit your personal networks for money. That's the bottom line.

Sorry to say that this one too will be binned or "pivot" to something else.

> Update: On a more detailed examination of those two states, I’m convinced the contrast here is due to differences in the sizes of the blocks. North Dakota’s blocks are more consistently small (StDev of 3.3) while South Dakota’s are more varied (StDev of 9.28). West of the Missouri River, South Dakota’s blocks are substantially larger than those in ND, so a single inhabitant can appear to take up more spaaaaaace. Between the states, this provides a good lesson in how changing the size and shape of a geographic unit can alter perceptions of the landscape.
A long time. Even the populated areas could be a lot more dense, and we wouldn't have people pushing each other into the oceans.

Hong Kong has a density of 6,620 people per square km. If the US was that dense, we could fit the entire population (317 million) in about 48,000 square km (the US has close to 10 million square km)

Of course, we probably couldn't have that many people living in that dense an area. But we do have a long way to go before we are pushing each other into the ocean.
"The West has become so dominant" that Putin was able to successfully leverage anti-western feelings in a semi-democratic way for 15 years now, with no end in sight. "The West has become so dominant" that Bin Laden is still considered a hero by millions of people. "The West has become so dominant" that anti-Western sensibilities still hold solid democratic majorities across the Middle East and South America (Egypt etc).

Honestly, where did you get this feeling that "the West has become so dominant"? From a military standpoint, Europe is bent on disarming: not even the UK can now afford the sort of effort that a close US partnership still imposes, and the US government itself is busy cutting everything it can. In fact, only a massive threat from Putin might be able to revive European defence budgets. Most European armies are creaking, from a technological standpoint; the only European nation pumping fresh cash in their armed forces is Russia, which is why Putin can afford to be so bullish. 1995 was almost 20 years ago, the world has changed. Bin Laden and Afghanistan militias showed that "the West" is, in fact, long from being "dominant" both at the military and cultural level.
The chart only shows presence or absence of human settlement. Just because there are people there doesn't mean there are a lot of people there.

I also lived in Manhattan for 3.5 years. Times Square cannot even compare to the absolute crush of humanity at Shanghai's Nanjing Street. Believe me, the US won't be filling up anytime soon.
