I don't really know about the nutrient balance without looking it up, but it's always trickier with multiple different types of plant in a single system. If you have a single plant system, you can just replace the nutrient solution every other week, like for like. If you have different types of plant growing together, you need to be a bit more careful with monitoring your NPK levels.

Then there's the basic maintenance that you'd have to do, regardless of plant type. Like rinsing the nutrient residue from the substrate every couple of weeks to prevent toxic buildup. Not particularly difficult, just drain the solution, pour water over the substrate to rinse, then add new solution.

But it's a new office maintenance task that would have to be done, and I can imagine things getting forgotten/skipped. If you like the idea of taking care of your own desk, then it's not particularly difficult. I'd be more worried in a medium office filled with these though; a small office is easy to take care of a desk or two, and a large office can afford to have a dedicated maintenance job, but a medium office is likely to be stuck with an awkward workload.

> We are not solving the problem of why medical care in USA is so outrageously expensive, we instead are solving the problem of how to pay for it.

Perhaps, but to the individual, the first problem is by far the gravest. One can feel outraged if the taxpayers are paying too much in general, but that is not exactly a life or death situation like not being able to pay for medical aid.

Also: Why can't you fix both problems?

>Common Lisp is the same

But the great thing about Lisps is that they can't get stuck in the past.

For example, if, say, Python didn't have decorators and you wanted to add them in, you'd have to present the idea in a PEP, get approval from Guido, write some code, et cetera. In Common Lisp, you just write some reader macros and that's it[1]. If Python stopped being maintained, it would lag behind other languages, but the fact that the Common Lisp spec hasn't been updated since 1996 doesn't make it any less modern.

A more relevant example: Lisp doesn't have hash table literals, which every "modern" language these days has, but those can also be added, trivially in less than fifty lines[2] of CL code, and suddenly Common Lisp is modern again.

It has nothing to do about articulating the ideas of capitalism. Capitalism exists whether or not we articulate it , the same way that the Andromeda Galaxy existed before we saw it in our telescopes. My point is that human nature seems to be very much correlated to capitalism.

And the important question is whether this is a fundamental characteristic of life, or is it just a feature of this particular version of intelligent life that we have in planet Earth? Or maybe is just a consequence of the evolution of our social system?

To state it clearly: is it possible to conceive an intelligent society collaborating by other means than the ones that we are currently using? Could catastrophe be averted by working together in other ways? Are we humans at all capable of this?

Currently, the answer seems to be no, but who knows.

Perhaps the concept of "uniqueness" itself is dying, rather than language being watered down.

"Everyone is unique." with the watered down version of the word "unique" just means "Everyone is distinct."

Perhaps people are beginning to collectively believe that nothing is irreproducible.
Many sleep scientists say that the most natural sleep for people is divided into two parts: night and at noon. The polyphasic sleep is directed to people who can't afford such amount of sleep for example because of their work. They can try the polyphasic sleep for some time. That's why this kind of sleep is only some NeuroOn functionality. In biphasic or monophasic sleep modes (as you said, the natural for people) this device helps you by waking up gently avoiding doing it during deepest sleep. That's why it is much more pleasant than using normal alarm clock.

Worked for me. Considering how the HN effect hasn't brought down this service I wonder if they pregenerated the ISO images. Realistically, you could do that for all the basic combinations of user selections since there are relatively few of them and then patch in the advanced customizations at download time if needed. (Although mkisofs is pretty cheap to run, so depending on your platform you could probably get away with no pregeneration.)

It's also interesting to see a distribution offer Razor-qt as the default desktop -- I'm looking forward to what comes out of Razor-qt's collaboration (merger) with LXDE.

A few similar services:

* Slax (a Slackware-based live CD Linux distribution) offers a build service where you can select individual packages (http://old.slax.org/build.php). I'm not sure if it has been deprecated for good with the new version of Slax being developed but it still works. Edit: From how it works it looks like Porteus was forked from Slax. I can't access their website proper right now but googling around confirms this.

* SUSE Studio (http://susestudio.com/) generates highly customizable live media images and VMs of openSUSE. Their gallery (http://susestudio.com/browse) is a nice feature. It requires registration.

Edit: I mistakingly wrote that Razor-qt is merging with XFCE rather than LXDE. Fixed.

Edit 2: While it's not strong evidence their download links (i.e., http://build.porteus.org/dl/$HASH/Porteus-RAZOR-v2.1-(i486|x...) suggest they don't pregenerate ISOs but they may cache them.

Well, patents, much like copyrights, only have value inasmuch as you are prepared to pay to fight it out in court. Copyrights are a little more straight forward, as "invalidation" (absent of plagiarism) is less common (though not unheard of).

Aspie is short for Asperger's, which is only a very mild form of autism, not that people calling themselves aspies necessarily have Asperger's syndrone, though some do. Many aspies have appropriated the term, however, because they know the business sorts calling themselves nerds will be repulsed by the term, and won't want to steal it from real aspies anytime soon.
> hygienic macros is a controversial subject

The amount of work which Racket people put into hygienic macros in the recent years gave effects. If by "controversial" you mean "less expressive" or "less composable" then those controversies should disappear already.

For example: http://www.schemeworkshop.org/2011/papers/Barzilay2011.pdf http://blog.racket-lang.org/2011/04/writing-syntax-case-macr...

Related: http://www.ccs.neu.edu/racket/pubs/

On a side note, it's impressive that language implementors write such a large amount of papers for almost all new language features. Compare it to the usual one-line point in changelog. This makes Racket foundations incredibly solid and learning it in depth easy and satisfying.

The syntax is not the problem for Haskell gaining acceptance for web dev.

Most web devs are frightened by functional programming idioms and will run away screaming when exposed to monads.

But the biggest problem imho is the type system that while great, makes things like making simple structs / named tupples or whatever you want to call them annoying and the lack of any "nice" way to just do OOP in it - and no, saying OOP is a bad idea and pretending it doesn't exist doesn't work.

Scala is a good Haskell for web dev. But it's too complex and has no chance of broad adoption against Node/Javascript, Ruby, Python and even PHP frameworks because for 90% of devs it simply doesn't bring anything good enough to make it worth putting up with the complexities stemming from the unholy OOP+FP mix.
Given your scenario of serving the right video to browsers, you shouldn't need to do UA sniffing because the browser should have the right accept headers so you can do proper content negotiation.

UAs these days should only be good for one thing, which is analytics. The browser should provide all the necessary information for other stuff through its other headers, such as Accept. Of course, I emphasise should because there's a wee bit of fantasy in that statement.

MELTDOWN: BITCOIN CRASHES TO $576
However, if Bitcoin is expected to be completely mined by 2140, then for all intents and purposes it has no glass ceiling. Note that our current post Bretton-Woods system has 42 years, and that Bretton-Woods lasted ~40 years before collapsing (leading some to postulate, with the current crisis, that monetary systems blow up every 40 years).

Bitcoin can last 40 years of use without hitting the ceiling.

Generally yes. This comes up occasionally with cancer patients; if they have an acute issue the hospital must stabilize them, but the hospital doesn't have to actually treat their cancer.

If they are very poor, they should in theory be covered by Medicaid, which will then pay for treatment. But this requires them to actually be in a condition (mentally/physically/education-wise) to figure out how to sign up and be approved for it, since coverage isn't automatic. Afaik, even if the hospital is able to determine the person should be eligible, they can't just treat the person and then sign them up on their behalf; the person has to do it themselves, and be approved before seeking treatment.

This is one area that I think the U.S. lags behind many other developed countries in: assigning a social worker to help people in bad situations navigate the system. I've noticed that with an uncle of mine who has MS, is on SSI disability, and can't really take care of himself. If he didn't have a family member who was willing to accept power of attorney and file all sorts of paperwork and make phone calls on his behalf, he would have huge problems, because he isn't able to do that himself, and the state has not assigned a social worker to help him out.
> nicely structured codebases whose language helped prevent a jumbled undocumented mess

What makes one think that any language can prevent "a jumbled undocumented mess"?
I don't think anyone is claiming it to be truly innovative and disruptive, as it's basically a warrant. But that doesn't take away from the value that the Safe creates, which is a standardized and well-thought out legal instrument that is freely available and modifiable.
I can't help but think that this would be a vastly better deal for the US than Canada. Canada already enjoys much of the benefits touted for a merger (protection of its neighbour, Free trade access to a massive market) while the US has much to gain (massive resources, land, water, better healthcare).

Assuming there was as much in common politically and socially as suggested (there most certainly isn't) the US's stock is very much in decline while Canada's is very much in ascendancy.

The only way a merger could happen would be as a merger of equals necessitated by bigger global threats alongside dramatic social reform/normalisation in the US (I.e. The US starts to catch up with the rest of the Western world in terms of social maturity).
They are actually pretty good at driving the prices down to something reasonable in most cases. While the headline prices are absurd, the prices actually paid by public and private insurers, whether Medicare or Blue Cross or Aetna, are much more reasonable. Not as reasonable as in much of the rest of the developed world, but the gap is not as gigantic as it initially seems.

The really big gap between the U.S. and the rest of the developed world on medical costs isn't the cost of individual procedures (once you've taken into account what insurers actually pay), but the much larger amount the U.S. spends on last-6-months-of-life "heroic care". If that were brought more in line with international norms, the overall cost-per-person numbers would be much better.
I believe no language can prevent a "jumbled undocumented mess", but it a language can get pretty far just by making paths to make documented and clear code easier than paths to no documentation and jumbled code.
This is a great start, however a key thing that is missing (at no fault of the authors) is patient outcomes.

Since no one have pointed out yet, I take the opportunity to recommend FPComplete.

It's a new company focusing on this exact problem. They offer tools like an IDE and deployment model. You can just sign-up on their website and start coding directly, you don't need to mess with setting things up. They also got School of Haskell which is a central place of really great tutorials ranging from tutorials on developing web apps to category theory stuff.

According to the site, for the 'Certificate of need', the main arguments seems to be following:
"A number of factors spurred states to require certificates of need in the health care industry. Chief among these was the concern that the construction of excess hospital capacity would cause competitors in an oversaturated field to cover the costs of a diluted patient pool by over-charging, or by convincing patients to accept hospitalization unnecessarily."

I couldn't understand this argument. Something seems to be wrong.

> So what is really needed is a startup culture that provides for years of uninterrupted development and focus.

Not just startups, but any worthwhile project really. From an interview with Rich Hickey:

"I started [Clojure] while on a sabbatical I had given myself. Not a break from work, but a break to work, as a completely free person. I gave myself leave to do whatever I thought was right, with no regard for what others might think, nor any motivation to profit. In releasing it, I had the normal expectations for a new language—that ten to a hundred people might use it. Maybe I would get some help or code contributions. It has taken off, and subsequently demanded far more time than the sabbatical I planned. So, I’m trying to recoup some of the investment I’ve made. Had it been a financially motivated undertaking, I’m sure Clojure would not exist, but I don’t regret having invested in it."

AIUI, this was the original genesis of Lisp - the S-expressions were supposed to be an internal abstract representation, and programmers would write "M-expressions" in a language a bit like Fortran. But everyone involved in Lisp realised you could just write S-expressions directly, and never got round to defining the M-expression syntax.

More recently, the GNU scheme project, Guile, had people working on pluggable syntax translators that would allow you to write Guile programs in TCL or JavaScript syntax, but AFAIK that project never produced anything completely usable.

However, it is equally true that industry never provided as much jobs, and not at the same conditions, that agriculture did. And the service industry never provided 50% as much jobs as the industry ever did, and completely excludes a decent percentage of workers.

And people are getting displaced in the service industry too, and there is nothing even pretending to replace the service industry. People go from A -> B -> C -> D, with A agro, B industry, C services and D ... well there is no D.
Anything that strengthens your algorithm and implementation skills is a good idea.

SRM matches are unique in the way that forces you to come up with a working implemetation in relatively short time. The problems present there will definitely help you to hasten your thought process.

In addition to this, I suggest you to check coursera's algorithm classes if you haven't already. Besides classic MOOC stuff they have an explicit section named job interview questions. These should help you better your algorithm knowledge.

What about the individual cluster models -- can they represent dependencies of variables within a cluster? For instance, I'm thinking about the "salary prediction" example. Is the salary variable considered to be conditionally independent of all the other variables, given the cluster assignment? Or can it learn something like an additive model, where categorical variables are associated with higher or lower salaries within a cluster?

Or to use another example, can it learn correlations between two continuous variables, to solve things like linear regression?
