No, that won't work. You can say, right now, and people do, "If we spend X building this thing, we estimate Y boost to the economy". You can't say "if we use X tonnes of concrete, we expect Y tonnes of Z to be produced" without the X/Y ratio being money. All money is is a way to abstract the worth of something from what it actually is.

Oh, and you can't pay your workers in concrete either. Or do you propose not paying them at all and just giving out rations to people living in barracks...?

The issues around Monsanto that get people fired up are more around their enforcement of their seed patents and the wide reach they've got on the seed industry as a result.

Monsanto has systematically worked to destroy access to seeding machines (which take mature crop and harvest the seeds from them) to prevent anyone from using standard farming techniques to build mature seeds. This in effect forces the average soybean farmer to buy ALL his seeds from Monsanto, because they control the supply to seeds.

Additionally, there's a presumption that anyone using non-Monsanto seeds is using a 2G seed that infringes their patent. Farmers are basically bullied away from approaching another source for their seeds.

Lastly, Monsanto is only able to effectively enforce these patents in the US. Soybean farmers throughout the rest of the world regularly use confirmed 2G seeds and their governments don't side with Monsanto. As a result, US farmers are forced to pay the cost of higher seed prices due to the "IP theft" going on in the rest of the world.
Heres a little incompatibility. The following code is valid Mathematica code, but the on-line parser rejects it

To fully appreciate the answer to this question, you should read the articles which I have linked in my other reply. Here are some relevant quotes (see articles for links):

"...For one, smaller countries such as Sweden are generally more susceptible to American pressure and bullying.

For another, that country has a disturbing history of lawlessly handing over suspects to the US. A 2006 UN ruling found Sweden in violation of the global ban on torture for helping the CIA render two suspected terrorists to Egypt, where they were brutally tortured (both individuals, asylum-seekers in Sweden, were ultimately found to be innocent of any connection to terrorism and received a monetary settlement from the Swedish government).

Perhaps most disturbingly of all, Swedish law permits extreme levels of secrecy in judicial proceedings and oppressive pre-trial conditions, enabling any Swedish-US transactions concerning Assange to be conducted beyond public scrutiny."

"The US has been seeking McKinnon's extradition from Britain for a full seven years and counting; O'Dwyer also remains in England and is the subject of a popular campaign to block his shipment to the U.S.; the NatWest Three were able to resist extradition to the US for four full years. These cases disprove, rather than prove, that an extradition demand from the US would be "swiftly complied with" in Britain. In contrast to the secretive Swedish judicial system, there is substantial public debate along with transparent (and protracted) judicial proceedings in Britain over extradition."

Its great to see people recognising the importance of local businesses! They're the core of most communities, and if we let them die then the community around them also dies, and will be hugely difficult to bring back again.

We're working on this problem for food shops at Hubbub[1], providing a way for people who would like to support local shops to order online, and receive delivery at a convenient time. Through doing that they get better (and often cheaper) food, and the money stays in their local community, rather than going to a multinational chain of supermarkets.

If you're as passionate about supporting local shops as we are we'd love to talk to you, we're hiring now! Check out the details at http://developers.hubbub.co.uk/ or drop me an email.

No citation needed as long as you understand both languages' runtime stack.

Python is an interpreted language that runs on top of a virtual machine (usually CPython). Types are determined at run time.

.py -> .pyo* (bytecode) -> VM -> OS

On the other hand, Go (and other C languages) have a different runtime stack:

.go -> binary* -> OS

Between source and binary are a bunch of compiler steps[0], but * is where both binaries are executed. Statically compiled languages do not have to determine types at runtime and therefore are able to optimize code paths much better.

Still don't believe me? Here's a Fibonacci calculation micro benchmark[1] I ran:

╭─ting@noa /tmp/fib ‹python-2.7.3› ‹ruby-1.9.3›
╰─➤ time ./go
1346269

╭─ting@noa /tmp/fib ‹python-2.7.3› ‹ruby-1.9.3›
╰─➤ time python3 ./fib.py
1346269

real	0.61s

Sidenote:

Java runs on a virtual machine (JVM) but it's performance comes very close to C languages due to static typing, JIT compilation, and heavy investment in the JVM from many companies.

hello.c

hello.tmp
(compiler)
hello.s
(assembler)
hello.o

"but their "holy" books can't rewrite themselves."

What happens when a bag falls of the transport, and grows a patch ? Next the seeds drop and make a bigger patch. Who needs to pay the patent fees mother nature ?

Another scenario: cross-breeding with other crops due to bees. Your strain could get copied to the field next door: NEW problem.

And for all the evil corporations out there: make as many seeds as you can. Next put them in an airplain and spread them EVERYWHERE you can. Wait 3 yeas for the strain to spread and sew EVERYONE.

In essence you a selling a self-replicating machine not under your control ... And they don't see an issue here ?

A better way to "reward" these companies (if we want genetic mutated strains) let them prove the worth they create and pay it off by the government, since they serve the entire community. (And hope there is no corruption or abuse on the system.)
Copyright doesn't apply to genetic code though.

> However having a language that combines this Scala feature with Go's exception-free error handling, would be awesome and a true solution that would make software run more reliable and with less crashes.

Do you realize that this is actually the case? Every Library/API I have seen in Scala until now uses the appropriate abstractions like Option/Either/Try/Validation/... and restrict exceptions to the most exceptional faults.

But anyway, if I had to choose between Go's horribly broken approach of returning multiple values and exceptions, I'll choose exceptions every day. Exceptions are ugly, but at least they are not blatantly wrong like using tuples for error codes.

Wikileaks redacts the names of people who may be in imminent danger. One would think that everything reported by Wikileaks is a "sensitive matter". If a report reveals the corruption and war crimes of a dictator that spurs a revolution where life is lost is that a "sensitive matter" whose reporting should be delayed?

It seems "sensitive matter" is a euphemism for something that harms the interests of the US/UK.

I'm struggling to imagine the audience for this; other than compiler researchers, LLVM's users seem to be primarily those who want to avoid using GNU code (in the form of gcc, which while not without its flaws is still more featureful and generally produces more performant code) for whatever reason (e.g. Apple), while Hurd's only users are GNU devotees.

The only problem I see here is his argument about placebos - while the placebo effect is a strong one (and I believe in it), there is a current lack of control over placebos (I e sometimes drug companies try to use placebos that cause side affects) that are currently used in the industry. Otherwise. This is an interesting idea.
Does the gas company do a great deal of R&D? Sure there's R&D involved in extraction and refining, but you seem to be talking about distribution. I think you may be talking about the (incorrect) idea that large infrastructure assets must be protected by state-enforced monopoly. Large infrastructure assets do not need this protection, and I blame Ma Bell for popularizing the idea (at least in the USA) that they do.

There's actually a huge natural gas rollout taking place in my community right now: http://www.summitnaturalgas.com/view/92 This is a large investment, which involves laying hundreds of miles of pipe and boring under the Lake of the Ozarks in three different places (in one location parallel to a privately-funded highway bridge). I understand that investors expect to be paid back over decades. Yet, no one appointed Summit to do this work, any more than anyone appointed Google or Monsanto to do what they do. Anyone in the world with an internet connection and a server farm is free to compete with Google. On day one when they turn the tap on their pipeline, Summit will be competing with numerous propane suppliers, the local incumbent electric companies, and even the long-term possibility (however remote) of another group building another natural gas pipeline. If Summit and Google don't need state protection, why would Monsanto?
>As a result, US farmers are forced to pay the cost of higher seed prices due to the "IP theft" going on in the rest of the world.

"IP theft"? The only IP theft is allowing Monsanto, a private company, to patent seeds.

You're totally correct. I should also consider the fact that you can prove that negative voltages exist. The opportunities for pedantically ignoring the context of the discussion at hand are endless.
Were there millions of depressed people in hiding, in 1955, waiting to come out of the closet in the 1990s? Was 9.3% of the American adult population (the percentage now suffering depression) merely suffering in silence, back in 1955? Or did the drug companies and their media flacks convert a relatively rare psychological condition into a growth industry through massive advertising and media hype (in other words, through the power of suggestion)?

The author is trying to claim that many (most/majority?) cases of depression are made up and hyped. They are trying to claim that it's impossible for there to be that many actual depressed people now.

But turn it around. How many (openly) gay people/couples are there today? Millions! But there weren't that many in 1955! So what happened? Was it all media hype? <sarcasm>Or are we expected to believe that all those gay people were suffering in silence in the 1950s?!</sarcasm>.

Of course all the gay people were suffering in silence in the 50s. People don't doubt that. So why the doubt about mental illness?

Money abstracts demand-pull from production and supply. But abstraction is a complexity management tool you don't need if you can crunch the raw complexity.

What I'm proposing is a "you want it, you got it" economy, basically, that starts from a premise of equal allocation of resource control (not resource use) and allows unused allocations to be reflowed to the use of those with more ambitious projects, with direct-democratic oversight.

For example, if a hypothetical Elon Musk wants to build rockets (a resource hog activity) then he'd probably end up having to make a public case he was capable of it to avoid being vetoed, but case made, the resource allocations of people who prefer to paint at home or study Tudor history other low-expenditure vocations would be diverted to the rocket project.

No, this would not fall prey to hoarding. Hoarding is stupid and gains you nothing in a post-scarcity economy. You end up with a huge heap of copper or whatever that you aren't using, looking like a selfish idiot and with a trashed reputation that follows you around and makes people not willing to work with you.
Whenjobs - a simple and powerful cron replacement
>Shooting someone is already a crime and always has been.

However, punishing people who do it does not make those they shot come back to life. Preventing harm is generally much more desirable than punishing those who cause it afterwards. And no, punishment does not do much to prevent mass shootings. Not having a large magazine IS it least somewhat effective to limit the damage one person can do.

Now the question is what preventive regulations are effective and whether their side effects are accceptable. I do have to wonder what exactly are the unacceptable side effects of disallowing large magazines.
Further more, to a comment I made earlier: http://news.ycombinator.com/item?id=5196565 and regarding the package managers.

As a Ruby developer, my first impulse was to use Rake but I started with Maven, trying to follow the bigger players, and I found myself struggling with managing various Maven dependencies and settings instead of focusing on getting the things done. Then I switched to Ant when I discovered the difference it makes when deploying to Heroku. Mu's compiled slug size deployed with Maven was 57Mb while the same core deployed with Ant today is 11.7Mb, give or take.

I'll commit the Maven configuration files soon, it is not my intention not too, but I will still search for a better solution. Any suggestions? Thank you for your feedback!

If you're testing your drug against a placebo, and the drug has a negative side effect, then you should try to make sure the placebo has the same/similar side effect. The whole point of double blind testing against a placebo is to test against something that appears similar.

Remember doctors aren't supposed to know what patients in a trial are on drugs vs placebo (that's the 'double' in double blind, the patient and the doctor is blind). If the real drug has a horrible side effect and the placebo doesn't, then the doctor will be able to figure out what patient is getting what, and you no longer have a double blind test.

I'm not sure how the article goes from interesting hypothesis (which it is) to near certainty.

>If we rule out changes in cigaret design and environmental factors as explanations for the enormous increase in lung cancer, what are we left with?

Seems like a false dichotomy to me. It can't be X, so it has to be Y.

>All of these would affect smokers and non-smokers equally. And yet lung cancer rates have not gone up for non-smokers.

This isn't necessarily true. It could be a synergistic effect, where some external factor increases cancer rates when smoking is also involved.
Thank you! Dissecting arguments and playing lawyer is fun sometimes, but not when the stakes are real. Even if legal precedent comes down for Monsanto, that just means that the legal precedent is wrong or incomplete, so who cares what the precedent can be manipulated to indicate... Monsanto is in the wrong here, regardless of how this thing turns out and regardless of how the law ends up being interpreted by the court.

Or, very simply, life expectancy has increased significantly during this time period. Since, "Of course, it takes years of smoking to get lung cancer", more people live to the age where they get lung cancer.
Seems more like an variation of what psych and behavioral economics calls the "what the hell" effect than "power of suggestion". "What the hell" effect says once your willpower fails and you give into temptation to begin doing negative behaviors, you are much more likely to go all in (think eating a single donut on a diet then polishing off the box). By making the cancer threat real post purchase and reminding of the ultimate consequence every time you light up, they may be pushing people to throw their hands up and just keep smoking.

Of course, like this article, this is just a untested theory I pulled out of my ass.
Isn't it at least in everyone's best interest that OTHER seeds than Monsato's seeds are planted and grown as well? Otherwise it may end up like bananas (all bananas the same DNA and therefore very sensitive to diseases).
Ask HN: Why doesn't anyone make a laptop like the Cr-48?
The Cr-48 was known for remarkably good hardware design. As a Chromebook, it didn't have high specs. They weren't sold to the public, but I guess they would cost about $400-500 max.

Why isn't there an equivalent now? All the laptops I see in that price range have very nice specs, but weak design. They don't seem at all durable, and they often have terrible battery life as a result of high-end processors.

Basically, what I want is a laptop designed like a Macbook for about $500, with the price difference coming from reduced specs. I don't want a superpowered laptop, I would rather have the battery life. Does this exist, and if not, why?
I am always disappointed that these Haskell-alikes don't just follow the Haskell spec -- too often they diverge for no good reason, and then there's no point.
