Considering the environmental impact of desalination and the power requirements, it doesn't seem like a proper way to end the drought. The answer is always going to be adequate planning and conservation, as well as improved infrastructure with higher-level planning. And legislators need to consider the true cost and benefit of catering to either the interests of farms and corporations or the people.

Living by the great lakes, I'm sure the people of California would lay a pipe across 1700 miles of the country if they could, but irresponsible usage of water is always going to drain whatever freshwater source is available. I do hope projects like these can help in some small way, though.

This also isn't the first time there has been a drought in any part of this country, obviously, and looking at weather in Texas recently, for example, you can see how quickly rain will come and go. There are large numbers of people in California. I'm sure that some of them must be smart enough to figure this out. Otherwise, we're looking at the beginning of another dustbowl.

The future of climate change is only going to make these problems more severe, and this obviously isn't a conservative solution going forward.

It's also interesting that the Santa Barbara desalination plant is mentioned. I lived in Santa Barabara recently (12 months ago) and I was unaware that there was a desalination plant there at the time during the drought. Recently I had heard that it was going to start up again, after never having ran more than 1 month in its lifespan. I would be surprised that that project is still behind its timeline, but then again, I wouldn't really be surprised.

(Edit: After 1 year, the city council voted to restart the plant last Tuesday.)

This seems to be the case as long as consumption continues to scale. I think you can come close to approximating a circa 1950's standard of living on very little income.
"We have to vent heat somehow..."

Yes, of course. And the heat of a star will make that heat completely invisible in comparison.

The "spectra" that heat would be vented at is infrared, which is infrared no matter the source.

Say you had some gargantuan fusion power harnessing space station in deep space. lots of assumptions here about alien cultures, but this is likely the easiest to detect. They will do whatever they do with their energy, and then vent the waste heat. That heat will be infrared. What does a dim infrared source look like (if even visible at all)? It looks like a brown dwarf. But this is assuming a lot. It assumes some alien would even build brown dwarf sized space stations. We don't know if or even why they would do that.
Yeah it's like Cytube. My use case was that I'm in a long-distance relationship and we both are huge movie buffs. YouTube just simply doesn't have the content that we want. Netflix does but it doesn't allow embeds so it took a bit more trickery :)
Well, the benefit to YC is that they can get a better feel for companies which may fully apply to a class for a somewhat nominal fee. Stronger branding, bigger presence, and just doing some cool shit to boot.

I agree that people need to be aware that their company should offer some benefit to YC as well, just simple business...exchange of value.
Of course Walmart have more employees because they have physical stores. Amazon have more computers instead :-)
To be clear, Tao doesn't say that he is not a genius.
Tao was known as a once-in-a-generation mathematical genius before he was 10 years old. (There was a magazine article about him and super-gifted education in Australia.) Both of Tao's brothers have extremely high IQ (>150).

Tao claims that you can contribute nonzero progress to mathematics without being a genius, but even so, the requirements he lays out aren't requirements that anyone with a childhood <120IQ has ever done.

What is blog post is saying is that math is not magic -- it takes brilliance AND hard work, not just brilliance.
Resolver One was an attempt at an integrated Python-based data flow programming system and spreadsheet, but it seems the company and product died several years ago: http://www.resolversystems.com. They did open source their experimental next-generation effort, but I haven't actually seen this running: https://github.com/pythonanywhere/dirigible-spreadsheet.

I think the core issues with spreadsheets are:

1. UI and user-facing representation - different tasks could be best solved with different representations of the same underlying model
2. Expressiveness - particularly including representational power, as in their computational complexity class—the basic spreadsheet model is not Turing complete

Eve (http://incidentalcomplexity.com) is a recent serious attempt to simultaneously address both.

Numbers has several features to address (1) (the ability to view arrange sheets next to each other in space, and to give rows and columns symbolic names). One could go much farther by offering, as you suggest, code-like views of the same models; such a view could use abstraction to compactly describe and edit self-similar structure, applying a single function definition to a collection of cells.

A key question with (2), however, is the degree to which the restricted computational power is a key advantage for the accessibility of the spreadsheet model.
PageSpeed is... a mixed bag.

It likes to yell at me that my font size is too small, and tell me to "set a legible font size". When I'm not actually setting a base font size and instead adjusting things relative to the browser's default.

Their recommendation to "fix" this is to specify absolute font sizes, which is the opposite of basically every accessibility requirement I've ever read.

Similarly, they complain that I'm not "leveraging browser caching" -- but the un-cached resource is the Google Analytics JavaScript.

It also doesn't catch the one actual user-experience-problem bug that I know about and am working to fix.

So while it's enjoyable to poke fun at someone through PageSpeed results, I'd take it with an extremely large grain of salt.

Some Federal agencies are restricted to X number of employees by law. They hire a bunch of contractors to get around this. It's not a great system.
Walmart's number would also be significantly higher if they included part-full-time employees. Walmart has been known to keep employees just under 40hrs so they don't have to provide full benefits.
How do you separate job and side-project IP?

Articles like this, and the frustrations expressed, really help to reaffirm my belief that Philosophy, or at least deductive logic, ought to be a necessary part of our public school system.
I am not sure that I understand what you're saying. Given a charitable reading of the presentation, the author seems to be saying that his standard explicitly specifies range of values, as opposed to the IEEE Float. It did not seem like he was saying that he could explicitly represent an infinite amount of exact, distinct values using a finite number of bits. Low level data structures are not my area of expertise, so did I misunderstand what he was saying or what you are saying?

I think the argument is that high profitability will increase demand for a stock to the point of it being overvalued.
It... it does?

I think we have very different definitions of the word "excellent". I'd call SourceTree's UI "barely adequate".
That's including warehouse workers. Amazon has far fewer warehouse workers than Walmart has low wage workers, so the average is substantially higher.
No. The set of "representable" (i.e. computable) numbers is countable (because the set of programs is countable), so in fact almost all real numbers cannot be represented.

Accounting doesn't work that way. You can have huge profits and reinvest them, but your income statement will show the profits in any case.

Yes, Amazon could be more profitable with different price points, but sales would take a hit, and thus their growth prospects.

FWIW, I think Amazon valuation is fair.

There is only one thing being valued by a rational investor: net present value of future cash flows.

Edit:

The only point I'm trying to make is that an investor, when they exchange money for a stock, is placing a bet on a single outcome: future cash flows. Of course there are plenty of ways to get those cash flows, but I find that most people get caught up in details like employee headcount and fail to grasp the single most important factor: compound growth.
The overwhelming majority of readers of Hacker News are not employees of the balooning private startups being discussed. Their companies have no equity exchange possibility at all.

Seriously, how many employees are there in the world of companies that could take "please exit" as serious advice? A few hundred, tops? And these are hardly impoverished folks to begin with, they could get solid six figure jobs at established tech companies in most cases. So why are we crying for them?
I'd suggest one of two things:

1. Contact The Guardian and share the issue with them

2. Forget about it, and delete this Ask HN post.
Considering the environmental impact of diverting whole watersheds to Southern California and the the power requirements of pumping it over mountain ranges, this seems like a great way to end the drought. The only reason it hasn't been done before is that SoCal has successfully externalized the cost of water. So, yes, it costs more to the residents of San Diego, but it's not a bad option when you consider all the people and wildlife that could be using the Colorado river.

And by the way, the "irresponsible usage of water" by the people of California is largely growing food for the rest of the continent. You may live near the great lakes, but you undoubtedly consume water from California. It's just packaged inside fruit and vegetables.
Under that reading, he's saying nothing: just represent the interval [-inf, inf] as "0" and call it a day.

So assuming that he's saying anything at all, he's at least being imprecise, and the actually claim should be something like "represent any dyadic interval using a finite number of bits".
I got the impression that the unum explicitly modeled a range of values, so I'm not sure that applies.

Not an expert here though.
They sent known commands to a known vehicle, they weren't live-fuzzing an unknown system.

The experiment seems less dangerous than not following decent tire-rotation policy, etc.

It's not that there's finite extra risk, it's what it is in relation to the baseline risk. Without that these comments are just useless scaremongering.
If I had a number system of -100, 0, and 100, could I claim all real numbers are represented, just not to arbitrary precision? With n bits, there are 2^n possible representations max. If you can say all real numbers are represented for n around 30, or 60, or even 1,000,000, then can't you say the same for n equal to 1 or 2?

Now I think we can say some representations are better than others (at least for certain applications). It may even be possible that some representation with a given n can be better in all cases than a representation with a larger n. So an n equals 1 system will obviously be terrible compared to many systems with n around 30 or 60. But I'm not really concerned with that point, just the claim of being able to represent all real numbers.
Replace "profitability" with "growth" and you get the dual problem.
I don't necessarily disagree with the strategy, but I'm not sure that's Bezos's own game as far as his personal finances go, or that his game is even that long in that respect. Bezos owns an 18% and declining share of the company, which he has been slowly liquidating. He owned 41% when it went public, and has been steadily selling around 1% of the company each year. So his own fortunes are becoming less and less tied to those of Amazon, except in terms of ego/reputation.
I saw that too, and it's the only part of this business idea that made an ounce of sense.

A twenty year drought is at the less severe end of what's possible.

California has had several 30 year droughts. It had one drought that lasted at least 180 years, and another drought that lasted over 220 years.

As somewhat of a tea addict (I just bought a kg of loose leaf tea last week) I think this sounds like a great product. I actually watched the video not expecting much, and I was pleasantly surprised by it's features and interface. If you ever make a home version, and I stop being a poor student, I would definitely be interested in something like that.

Personally, My one complaint would be about the selection, I'd like to see more types of tea/specific regions (Darjeeling, Assam, etc.) relative to the amount of 'additives'. But that's probably just me being a tea snob :). Is the selection up to the owner of the premise, or do you decide the stock for them?

"Python Bridge, officially known as High Bridge, is a bridge that spans the canal between Sporenburg and Borneo Island in Eastern Docklands, Amsterdam. It was built in 2001 and won the International Footbridge Award in 2002. The bright red bridge spans 90 meters and was designed by Adriaan Geuze of the architectural firm West 8"

Coincidentally, Amsterdam can be considered the birthplace of Python, where Guido used to work at the Center for Mathematics and Computer Science (CWI).

And now for some obligatory functional python.

That's fine, but then you're representing dyadic intervals, not real numbers. Simple question: what's unum[sqrt(2)]?
Maybe we should lobby for change ;P
Sure, but there are many ways to get future cash flows. A significant difference in the valuation of the two companies is that with Wal-mart, the expectation of future cash flows (and therefore present value) comes primarily from its present size, the cash flows that brings, and its expected ability to continue bringing in such flows. Whereas with Amazon, which has much lower current market share and cash flow, the market is "saying that Amazon's growth prospects outweigh it relatively smaller size". Hence the proportion of expected future cash flows that investors expect to come in the form of future growth is significantly higher with Amazon than with Wal-Mart. Therefore you would expect Amazon to have a lower current size and current headcount per unit present valuation, even if there were no differences in productivity.

What I was criticizing was just using the ratio of present market cap and present headcount as a meaningful metric, when comparing companies with very different growth expectations. That effectively becomes a restatement of the different growth expectations: Amazon has the same market cap as Wal-Mart but its present size is smaller in almost any way you could count present size (sales, headcount, etc.).

Now going offline with things is no promise that there will be more shared culture, but there's more of a chance than a world where we have access to exactly what we're interested in all the time (via cellphones, especially).

There is a feedback loop to our lives online that is not present when we're forced into social situations with people that we don't necessarily see eye to eye with. Note, it's not always fun to be with people we don't see eye to eye with (witness: family car trips) but if we don't learn conflict resolution and tolerance there, the internet sure isn't going to help.

Tea is popular, but mostly blended tea from teabags, served with milk. If you ask for "tea" with no qualifiers this is what you will get. High quality tea is hard to find in offline shops. I do like good tea, but I mostly drink teabag tea with milk because of the cost and convenience, and I don't see how any tea robot can win on those features.

One important factor that Americans might miss is the ubiquity of electric kettles. We run 230V nominal (in practice still 240V) mains, and 3KW kettles are standard, so boiling water is much faster than it would be in the US.
