You need to learn how the stock market works. Before real scientific analysis, your predictions have no value at all -- not a bit. And after scientific analysis, they will turn out to be random guesses, as has been demonstrated again and again by people who wanted more than anything to discover the opposite.

Here's why: http://arachnoid.com/equities_myths

And remember -- people who actually have money, and who are seasoned investors, aren't misled by sites like yours.
>"We should hire mid-tier developers based on code review, typically based on open-source code."

While I agree with sentiment this is not always possible. Company I work for, strongly "discourages" to sharing any code outside organization and also open source contributions.

Its not hard and fast requirement but recommendation to avoid code leak and sort of saying we might re-consider your job in passive language.

I know tons of companies right in SF who have "ultimate secrecy" for coding and also what they can contribute to open source.

There is no possible one solution for this problem.
I'm not sure the material is viscous enough for that, it might have a certain degree of roundness regardless.

In my head the shroud is directional, which means you'd need another actuator at the nozzle. If he's using off the shelf cnc software that could actually be complicated to implement.
The design of any technology is ultimately informed by an implicit philosophy.

In this case, "End-to-end arguments in system design" [SRC84] disagrees with you.

In fact, I'd say the whole "net neutrality" issue comes about from last-mile ISPs fighting the simple-network philosophy, as content-aware "services" have much higher margins. Without competition there is no pressure to keep their costs down, so instead they spend more to build a complex network for the goal of decommoditizing their offerings.
I'm working with our SaaS customer service and good support guys are always natural on using these two words when a customer is looking for an affirmation.

Just think that this is a good metric to add and see how specific words help conversions and upsells for non-customers. Hopefully there's something more automated that I can use to measure, though.
Sorry, that comment was perhaps needlessly gnomic, and it's a throwaway line anyway :) I just imagined that the obvious way of marketing this would be (in addition to emphasising the convenience aspect) to somehow imply that if you love your family enough then you'll outbid other people, allowing you all to jump the queue.
Let's create an HN exclusive product?
I'm sure that there's variety of talented folks on here ranging from frontend/backend developers to designers, to marketers, accountants, project managers, investors etc...

I'd be interested in seeing what we could bring to market if we were to collectively create something. It would certainly be a hit with PR if it were a success: "An product created by a collective of online community participants is a major success!".

Seriously though, if anyone is interested or has ideas to contribute I'd be willing to work on an idea with you guys if it's right. As per what I can bring to the table? I have a team of frontend and backend developers (Ruby on Rails) that I could get on board, and they're fantastic!

Just throwing the idea out there, of course we would have to work out the inner-workings and details but I'm interested in hearing your thoughts!
I bet you work in an inexpensive paper/theory field (math, theoretical physics, CS), and your parent poster works in an expensive wet lab field (bio, chem, eng).

The cost/benefit tradeoffs are atrkly different.
Ask HN: Interested in CoreOS/Docker on PS4/PS3?
I'd like a cheap way to run several docker containers for personal utilities. PS4 and even PS3 specs would meet my requirements.

Has anyone tried this? Anyone interested in working on it?
The issue is more complicated than just socialized vs. non-socialized. There are many countries with privately run healthcare system that are perfectly good, such as France or Switzerland. And there are countries that combine both public and private provision of healthcare and have it work perfectly well, such as Sweden or Singapore[1]. The US actually does run some hospitals directly, the VA, and I doubt this made the news outside of the US but there was a huge scandal a while ago concerning them.

The current US health situation is the end result of a long process of complicated schemes to provide more healthcare to Americans without any clearly visible costs in ways complicated enough that there are no obvious deficiencies. For instance Nixon's scheme[2] to lower costs by preventing competitions between hospitals[3] is still on the books all these years later. Given all the government interventions in the healthcare market combined with an unwillingness to bite the bullet pay for or subsidize most people's insurance directly has left the US with a healthcare system that is neither government run nor free market, but something far inferior to both.

[1] Singapore has a really weird combination of forced savings, mostly private payment, and mostly public provision which is really weird compared to everyone else but somehow gives them really good health outcomes really cheaply. I don't think the US could make that system work, though.

[2] Is there something Nixon didn't screw up? Well, besides repairing our relationship with China.

[3] Back in the day everybody knew that the USSR had a far more efficient economy than the US did (the Soviet statistics said so!), and one way people explained this was that the Soviets weren't wasting resources on competition but instead just figured out the best way to do something and put all their effort behind that.
Interesting. Have you worked with a company like Exxon or BP? I've obviously only met a tiny fraction of their contractors, but I do have a reasonably large sample of both small and large contractors across several fields, and they all bill hourly, and that expectation seemed pretty fixed into how their systems worked. At least the ones doing consultancy-type contracting on an open-ended contract over a significant period of time do so, whether big consultancies like Technip or Booz Allen Hamilton, or small shops like boutique metallurgy consultancies. Different billing applies to one-time deliverables, construction work, equipment sales, etc.

Of course in practice the work is usually chunked into day-sized segments anyway. If you have three of your people working on a particular project all week, and then send an extra two people along on Friday for a site visit, it's reasonable to bill 17 person-days. But in the cases I've run into that still gets formally invoiced as 17*8 = 136 hours.

> they got the same amount of randomness

It's hard to quantify randomness. It's possible that whatever test(s) they were using reported similar results, even though the data from a lens-capped camera might be somewhat predictable if you know the physical properties of the device.

I know individual models of camera frequently have very similar thermal and electrical noise profiles, so that wouldn't be too surprising to me.

I know of schools that don't give W2s, pretty sure that is just illegal and also pretty sure those schools get dinged by the IRS regularly for this.

some student friends of mine get paid in very sketchy ways, like in personal checks from the department administrator, and don't even know if the university has done withholding. these are ivy league schools too! every few years there is a big IRS thing but nothing changes.

universities are shady as hell.
Is it like a phone's keypad, where you have to press the same button multiple times to get a different letter? Or is it a combination of buttons that you have to remember for every letter?
In a startup I've worked on, we did estimates based on hours, but also had the "no idea" tasks. We would then make sure to alternate sprints to work on well estimated tasks (as you say, "linear" tasks) and others to work on the hard ones, without a set deadline; or split the team effort in that manner.

I think that's a better strategy than making wild guesses and ultimately falling behind schedule, but at the same time maintaining cadence, which buys you power to sometimes say "hard things are hard, I don't know when it'll be ready to ship".
If you seriously believe that, you are indeed being an idiot.

Your logic reasoning skills may be pretty good, which is a component of reason that many people lack. What you seem to lack is a useful mapping between reality and propositions. And from false premises, unfortunately, even flawless logical derivation cannot produce any useful information about the world.

When wwweston critizes your black-and-white thinking, he is not suggesting (I think) that there is some kinda-maybe-not-quite-true-or-false truth value. Rather, he suggests that the choices you are implying actually have more than two mutually exclusive possibilities. In particular, words don't actually have "real meaning", words routinely have tons of meanings, heavily depending on context, which is why you cannot make a simple binary decision as to whether something is or is not an X. It's somewhat unfortunate, as that leads to lots of confusion, but there is nothing logically wrong with it, it's simply a matter of fact that one has to consider when one wants to construct sound arguments, so as to never equivocate any two different meanings of the same word. The binary determination is only possible either for cases which evaluate to the same truth value with every conceivable definition of a word, or once you pin down the exact meaning that is intended in a given context.

Part of the problem with your arguments indeed seems to be equivocation. There is a definition of slaves that hinges on complete unfreedom, which is roughly what most people think of if you don't specify any specific definition - let's name that a slave1 for the purposes of this discussion. Then, there are definitions based on certain philosophical arguments that try to show how, for example, socialism produces similar power structures to "traditional" slavery in certain regards, we'll call that a slave2. (Similar arguments exist for capitalism, and many other power structures.) Now, you come along and say "requiring doctors to provide a service is making them a slave2", which is actually a perfectly reasonable statement to make - except you obviously imply "which is the same as a slave1, and everyone knows that being a slave1 is bad, therefore, requiring doctors to provide a service is bad", and that's just an equivocation fallacy that you employ to avoid having to justify why one is as bad as the other, where that is not the slightest bit obvious if you look at the actual circumstances that slave1s lived in and that doctors live in nowadays.
You've clearly given this a lot of thought, but we are at odds with one another. I hate point-by-point refutation, but just a few thoughts I have...

All of your points are predicated on the notion that rents would decline if you eliminated RC. I think that's... hopeful. I mean, in some places you seem to suggest that landlords are beset by low rents (not improving the place because of it, hoping their longstanding renters move out). So certainly all of those landlords would raise rents. And non-RC units will, what? Reduce their prices to equalize the market? I doubt that. And now you have higher rents all over the city. And that's good for people? Because it might spur more development? But development is slow and favors up-market construction.

And blaming lack of development on the tenant-displacement laws that are part of rent control? And suggesting that rent control is the problem is a farce. If it's these laws that are the problem, why not write a post assailing THEM? And rent control laws are the reason people protest these developments? Really?

Being hard to move... ok... so go tell the family that you're raising their rent so that they'll get used to paying market rate. That way they'll be able to move anywhere they want! What a great deal for them!

I know for some reason you think rents will go down. That developers will build new buildings at high expense in this seismic-zone and then undercut the existing market (of old buildings with tiny rooms and few modern amenities), ignoring the fact that if they build up-market they can write leases at $50/sqft and have no trouble renting out the entire building well before it's finished.

Finally, if you actually read rent control laws, you'll see that they are not these cartoonish works of absurd leftist ideology, they do make carve-outs and exceptions for capital improvements and other large expenses to be passed-thru as bigger rent increases to the tenants. They are surely not perfect but property owners are a very powerful bloc and their voices are heard in the law IMO.
Thanks for the kind words.

On institutions: I did my PhD at the University of New Mexico. A fine institution, but also not Harvard / MIT / etc. I went there because Carl Caves had created a great environment to work on quantum information. Carl encouraged me to work on whatever problems I wanted, but was also happy to provide advice upon request. My fellow PhD students enjoyed similar freedom, and I believe it benefited them enormously as well.

Edit: To clarify my earlier comment: I am certainly _not_ saying that it is universally the case that people are able to choose their PhD project. That's not true, especially in fields involving expensive experimental equipment. I'm saying that someone not able to choose their project is being badly trained. It should count as a very heavy mark against doing a PhD when the advisor believes they should control the direction of the project.
How do you decide if the water in your bathtub is warm? Stick your finger into it and see for yourself.

Similarly here, you use your models to predict something, check if they predicted it right, and either try to fix them or ditch them completely.
Some neuroscientists and cryobiologists think that cryonics deserves a second look as a way to try to turn death from a permanent off-state into a temporary and reversible off-state by approaching the problem as a challenge in applied neuroscience. They have set up the Brain Preservation Foundation to raise money for incentive prizes to encourage scientists to push hard on the envelope of current and reachable brain preservation techniques:

Two prominent figures in the skeptic community, Michael Shermer and Susan Blackmore, have lent their names to the Foundation as advisers, so they apparently consider the idea scientifically defensible:

Hey sprkyco,

I have java development experience and would like to get in security domain. My full time job ended in May. I live in San Diego and the job market here is not as great as in northern CA. I would be in interested in the entry level positions advertized in the Whitehat Security career site. where should I start? Since I do not have any security experience submitting my resume may not be an effective option.
Thanks,

An Amex card is no harder to get than a MC/Visa. Costco has done quite well in the relevant middle-class-american-suburb market with an Amex-only policy. This isn't the barrier.

The retail penetration, however, is the barrier. If you can't use these things mostly everywhere, this service is going to be no more successful than Google Wallet.
FTA: "The news site The Information previously reported that Visa had also agreed to work with Apple."
>If I know the complete wave function of the system, then knowing the wave function at a future point in time is trivial. Just apply the time evolution operator.

I was under the impression that the Bell experiments indicated that there was randomness not accounted for by our inability to measure with 100% accuracy (because of the uncertainty principle). Doesn't the falsity of hidden variable theory mean that actual randomness is present in quantum events, and we can't predict the future state perfectly even if we had the exact wave function of the system?

I could be totally off base here; please set me on the right track!
Is Obamacare going to be the first step towards making the U.S. a socialist country ? Is the true goal to reditribute wealth ? It is meant here, http://www.mymustardseeds.com/ultimate-goals-of-obamacare.ht....

Apple working with 'INSERT ANY CC PROVIDER' on iPhone 6 Mobile Payments...

More interesting is the question which technology will be used. NFC has to play a role here, because the technology is in the market and scalable. My weirder and more riskier bet is that NFC on the Apple wearable will refit all older iPhones with mobile payments. Until now noone has put NFC on a wearable, even though it makes most sense to have it on a wrist.
With New 3DS Model, Nintendo Continues to Woo Hardcore Gamers
Sadly the article is inaccurate on a few counts :

1) social security taxes

The government has carved out a special status for these Phd "employees", which means that social security taxes are not paid for these employees, and of course the resulting burden is carried entirely by the employee. Ironically, and because this results in a higher effective wage for these young people, who are too young to care about pension and generally don't need health insurance, they actually like this part.

a) you can't get unemployment if you get fired, or after you "graduate" (which amounts to firing with a nicer pink slip for 9/10 Phd employees)

b) you don't build up pension rights

c) health insurance is the employee's problem (though many universities "solve" this through private means, but it means significantly less coverage)

c) No paid holidays (again, universities sometimes make up for this, but not the same as private sector. This is pretty much the only European job I know that doesn't come with 4 weeks paid holidays. This is legal, because it's not a "job", legally speaking)

d) very few other employee rights (e.g. no rights to unions, even though I doubt any union would stand a chance their anyway). No rights if you get fired. If a university downscales (thankfully, doesn't happen often), these people are treated worse than contractors.

2) They are most definitely not "civil servants"

The legal differences and problems this poses are too numerous to go into. Let's just say, once again, the Phd student is the loser here.

3) about the one thing these people do have going for them is that government sponsorships are tied to the person, and include a (small) amount to the university and the pay for the Phd student him/herself. So if the university fires a Phd student, they lose the funding.

In other words, unless you commit a crime or something as a Phd student, if you're on a government scholarship, getting fired is not a concern.

Being a Phd student on either a university or private scholarship ... you don't want that. Or, at least, make DAMN sure you like your promotor.

This article doesn't even mention the Hyperloop once. In doing so, it makes me think that the author has a one-track mind, hell-bent on making "high-speed" rail the answer to any and every question.

Ignoring serious technological advances won't make them go away. I admit, the Hyperloop hasn't been built before, but is that really an issue for a guy that runs a company that makes rockets that routinely go to space and back, or electric cars that people actually want?

Given the merits of Musk's proposal, we should really be rethinking the entire California rail project. If we don't, we could be saddled with yet another expensive and obsolete infrastructure project for a long time to come.
I expect there'd actually be more fraud under a free market system because catching fraud (past a certain point) is expensive and companies are only going to put the resources into catching fraud if it continues to exhibit a positive ROI. Or maybe NZ bureaucrats are insulated and dedicated enough to do the right thing rather than listen to the outrage of the voters when fraud makes the news, but I wouldn't expect that to be true in the US.

The whole advantage of Apple getting into payments is the fact that they have millions of credit cards for their customers. The advantage is muted if they require those customers to get new cards. It is quite safe to assume they are working to partner with all of the major credit card companies and AMEX happens to be one of them.
