I think that's yet to be determined. They're taking a non-standard strategy with releasing media, and there's potential that it could just work for them.

Sure, normally TV spreads by people talking about it across a season, but normally there's also the problem of "oh I have to now 'catch up' and the resistance that comes with that. This is a no-pressure situation where you can tell your friends about how awesome a show is, and they can go watch the whole show with no constraints or time pressure or schedule. It embodies the goal of the Netflix service.

Sure they're not getting the standard 'talk about a show for 6 months as episodes come out', but instead they might get a viral chain effect where the season isn't constrained to that time period either. Ultimately their goal is to grow subscribers by hooking them with valuable content they can't get anywhere else.
Yes. Here's why: if your startup succeeds, your views about staying in school may evolve.
Sorry to hear of your untimely loss.

If you're very busy and other methods seem too time-consuming, perhaps a simple Tumblr page would fill the need in a short-term basis, and could be curated into something more permanent later. But the Facebook idea above is also good, as so many people use that platform.
The article mentioned that the top-end battery weighs in at half a ton --- not exactly hot-swapping material. Also, when it comes to safety, center of gravity, chassis rigidity, etc --- I'm sure there were a myriad of engineering decisions beyond weight that go against hot swapping. And that's not even getting to added cost and logistics of maintaining a network of skilled battery swap experts, "ownership" over the batteries (e.g. who is responsible for replacing failing units if they are shared around the community of Tesla owners).

I'm probably just scratching the surface with a minute of thought. I'm sure that the folks at Telsa have been over this ground, and much more.
This article will be completely obsolete in a year, but because the owner's manual failed to convey that point it will sit around people's minds for years.

Fixed above. Also, my impression from the article is that Tesla is telling people to derate the mileage estimate by more like 10%, not 25% or 50%.

The battery for the Model S is the entire base of the car. It's over seven feet long, weighs more than half a ton and costs about $12,000 to make. I'm sure they would have loved if it could have been swappable, but getting there from the current technology would mean a lot of compromise that would almost certainly not be worth it.

I think you are missing something: where do you put the replaceable batteries?

Tesla's battery packs are distributed throughout the car, both to allow for cargo space (not having a trunk would be something of a minus) and to distribute the weight of all those batteries. I am having a very hard time envisioning a way to achieve both of those goals while making the batteries replaceable.
If you only look at what you are looking at, you'll get discouraged. I've had a few items on sites that got completely destroyed in the comment sections, but a month later, I still have several visitors from those sites on those same articles, and many of them are returning visitors. So, while your initial analysis is correct, I think you will find the long-term surprising. The finding is that despite all the negative comments, the vast majority of the readers actually do like it, but they aren't going to speak up against the maelstrom.
I suggest that your point is that if you want to be a better mathematician, you need to get comfortable with proofs. Sure, well, so what?

If a programmer tells you they're interested in math, and they don't want to learn proofs, it's possible that they're saying the ludicrous thing that your article claims they're saying... but it's more likely that they're saying "I want to use the calculating techniques of math". Speaking for myself, I have a very modest interest in getting better at proving, but significant interest in getting better at calculating.

As for the for-loop, the reasons may be wacky (wackier, I admit, than interpreting for(;1;); ), but there's something fundamentally different between the for-loop and the summation. In the for-loop case, everything you need to know to interpret that code is written down in an obvious place.

I have to use C because the hardware I use at my company requires it for a number of reasons (performance is not one of them). C was my first language and it is responsible for a very substantial part of my income. But I find the establishment of C and intel arch the reason you still have to use a keyboard chip to enable 32/64 bit mode in a computer:

https://github.com/eduardordm/sisop/blob/master/sisop.asm (see line 110)

C can be low level, but it is mainly a high level language and it will 'distort' programmers just as any other language. Just because it doesn't have simple features it doesn't mean it is closer to the hardware.

C teaches you how to destroy memory, not manage. malloc+free are most harmful functions of the history of computers. (and I don't think I'm exaggerating) You can actually evaluate how awful a C programmer is by counting the number of mallocs/frees he uses.

Oh, I don't like C, by the way. (but I'm really grateful for knowing how to solve problems using this handicapped tool)
You're right, those are all drawbacks. They all pale in comparison to the advantages, though.

Swapping my car's battery should be as big a deal as swapping the propane cylinder on my gas grill.

And yes, batteries these days are perfectly capable of monitoring themselves in a leased-usage scenario. Your laptop battery has its own CPU and EEPROM, for instance. To understand why, see any recent news story on the Dreamliner.
&yet put on a great RealtimeConf for two years running. I heard only good things about the pre-conference RedisConf they did last year, so I think a WebRTC conference will be a huge success.
I don't think they "make no sense", and I'm not sure a propane heater is the answer, but an electric heater is going to require the use of battery power otherwise used for getting you from point A to point B.
(Shrug) Engineering ultimately has to serve real-world requirements, above and beyond all else.
They are professional organizations, not just publishers. As professional organizations, their primary goal is to support their members and the betterment of the field. They may not always have paywalls; unlike Elsivier, their organization exists for purposes other than getting money from publications.

The co-chairs of the ACM Publishing Board recently wrote an editorial, "Positioning ACM for an Open Access Future": http://cacm.acm.org/magazines/2013/2/160170-positioning-acm-...

It's not enough, but it's a start, and I'm hopeful. I am a member of both the ACM and IEEE, and I want both of these organizations to move to a fully open access model.
Here's a hint from the usability department:

Underestimate the remaining miles. Even if that makes you look bad up front. Its an eerie form of cognitive dissonance when your reserves are dropping faster than you consumption and the wheels in your mind spin wondering "will I have enough". You never forget this feeling. Even if its just a test drive, you'll associate Tesla cars with that feeling forever after.
Hey there, I work on Connect at Stripe. Sorry if there was any confusion regarding refunds and Connect: you can both make refunds back to the customer, and refund your application fee back to your tutor.

Would love to help clarify things, feel free to email me at amber@stripe.com as well. (:
It would be nice, sure, but your propane cylinder doesn't cost thousands of dollars or weigh half a ton. There are physical realities to contend with.
The battery pack is not distributed throughout the car, and it is actually designed to be somewhat hot-swap capable in the Model S.

It's just that for the majority of people, battery swapping makes no sense. They can charge their vehicle over night at very very cheap prices and have enough range to serve them all day. If you insist on taking a cross-country roadtrip, rent an ICE - the infrastructure is just not there yet (or peoples minds have not accomodated - see this article).
I think the concept of "group monkey dance" is a good one- mainly, I think its insightful to point out that people will collectively be much crueler to someone than any of them would be on their own. This is something us nerds are intimately familiar with from uncomfortable social settings in highschool, but it didn't occur to me that the same dynamic might be at work in big internet discussions.
Electric heat via resisters is very simple, but very inefficient. (EDIT: Thermodynamically space-heaters are 100% efficient, since they always convert their source energy into heat. They are inefficient from a monetary point-of-view.)

You can do electric heat via heat pumps, but it requires more equipment and it doesn't work if it's too cold. You can get about a 4 to 5 advantage over plain resistance heat.

Gasoline engines lose a lot of energy to waste heat -- but sometimes that waste heat is exactly what you want.

IANAL either, but there's no law against making income, there's a alw against accepting employment.

If you open US payment processing accounts without US citizenship or a Visa that allows it, take 6 figures in payments while out of the country, then try to move it into an anonymous payment account across international borders, someone's going to investigate it.

Yes, and we've just read about them in the New York Times.
Nice blog post!
You're not the first person with this idea: http://www.wired.com/autopia/2009/05/better-place/

To some extent there is a standards problem: there is not a common battery pack (like there is a gas tank fill point). But even if there were, the batteries would continue to run down after delivery (unless supplied with a non-trivial amount of power). And the space required to physically store these batteries would occupy a lot of volume. After all, gasoline/diesel is far more energy-dense than modern batteries.
Ask HN: How can I make this page convert better?
Currently 30% of visitors to this page click and go to the signup page. (Which I think is pretty good) Then about %3 of that convert to paying customers.

I think something about this could be optimized better, Im not really sure what, just a gut feeling.

Any thoughts?
I'd say the boycott has reached the point of crossing the chasm into adoption by mainstream users. There are still new people signing up all the time, but the pace is low.

A bottleneck to mainstream use is the lack of overlap between hackers/devs and people who are most influential in academic publishing, such as senior editors. To developers the question is: if editors want to post their articles on the web, why don't they just do that? To editors, the question is: how can I practically make my journal open access? There is a need for technology to assist in setting up open access journals.

Some people are working on solutions, but it's not obvious what that solution will ultimately look like. There is some trial and error happening, and I hope great progress is made while the problem has the attention of the community.
Awesome! Keep up the good work, lucky to have found it. When's the next session coming out btw?
Not really. Once you get into understanding how investors, investment and VC, etc. work, the mathematics of risk and payoff become very clear. If you, as an investor, are throwing millions of dollars into a product that requires millions of dollars, and has only a 10% chance of success, then you a commensurate share of the payoff as well, which may even be most of it.

At my last job, I got to choose the balance between salary and equity I wanted -- and I really had to calculate if I wanted to earn a little less (or a lot less) in exchange for a greater share of future profits. Or to earn a little more (or a lot more) in exchange for giving that up. And having gained quite a bit of knowledge from the investor side of things, at least here in the tech industry in NYC, I don't think it's accurate at all to say it's "usually an exploitative relationship". At least, as long as employees bother to figure out how it all works.

Of course your employer can sack you or withold a raise. But of course you can leave for another company, or tell them you're leaving if they don't give you a raise.

But you've got to have enough skill to be of value, and enough negotiating skill not to be taken advantage of, as well. Just like a company has to have enough skill not to hire not to be taken advantage of by its employees -- the employees who don't contribute, the employees who spend more time playing politics, etc.
Thanks. I Learned something new today. I had no idea that male circumcision reduces the chances of contracting HIV, but it does.

http://www.engenderhealth.org/our-work/major-projects/male-c...
I am also astonished by that number, but circumcision certainly seems to be an important way of fighting HIV.

"There is compelling evidence that male circumcision reduces the risk of heterosexually acquired HIV infection in men by approximately 60%."[1]

"Evidence among heterosexual men in sub-Saharan Africa shows a decreased risk of between 38 percent and 66 percent over two years"[2]

But Circumcision Rates in Africa are relatively high anyways, due to the population's religious background.[3]

Quote of New York Times Article: [4]

"Among those are 14 studies that provide what the experts characterize as “fair” evidence that circumcision in adulthood protects men from H.I.V. transmission from a female partner, cutting infection rates by 40 to 60 percent. Three of the studies were large randomized controlled trials of the kind considered the gold standard in medicine, but they were carried out in Africa, where H.I.V. — the virus the causes AIDS — is spread primarily among heterosexuals. "

"Other studies have linked male circumcision to lower rates of infection with human papillomavirus and herpes simplex Type 2."

" The procedure has long been recognized to lower urinary tract infections early in life and reduce the incidence of penile cancer."

So i guess it just all adds up in a way.

That being said, the number of over 18 billion Dollars (according to the article) being spent on this issue still astonishes me...

It's always a shame stories like this get so much attention. Lots of 'PayPal is evil' comments. A completely one sided 'I'm so innocent I didn't understand' perspective. All companies have issues once in awhile. I get that people are especially sensitive with PayPal because they deal with money and are huge. But come on. If you at all expect to be making more than even a few hundred dollars a month there's an onus on the 'victim' to read up on what they're doing and set things up in an appropriate manner. This situation sucks but it'd be nice if there was a balanced view on it and more helpful dialogue than 'Never use them! Go to court!'
Worked at Tesla and never got to see the 'recharge now' warning. That would be quite alarming.
Off topic, but...

Luxury car rental company? Please tell me more (like do you have a website??)

I ask because I know of a couple of luxury car rental companies, but there is one ore more things about each of them that make them exceedingly unpleasant to deal with. I would be interested to try doing business with a luxury car rental company that is run by people who also read HN - seems to be a good signal for not-totally-fucked-up business practices.
yes, very!
Apparently -- see other comments in this thread, and the ones that were made the last time this came up in another HN story -- the Model S battery is designed as a module for rapid replacement.

Of course, without an industry-wide effort to standardize a few core battery sizes for different applications, it's a moot point. That is the problem that I wish Musk had set out to solve.
"There is a need for technology to assist in setting up open access journals."

I just hope they don't start hosting them on Facebook.
Contact one of the Silicon Valley law firms that's used to dealing with these things. Don't go to some cheapo ambulance chasing lawyer who doesn't know what to do. Even if you cough up $20k in fees to a law firm it's worth doing. They'll help you set up a company for your product and steer everything through that to unlock your funds. A lot of advice on here is overly negative and misinformed. As someone who has had to deal with changes of legal status, setting up companies as a foreigner, and has dealt with the hell of PayPal account freezing, I can assure you this is fixable if you work with a reputable experienced law firm.
The thing you are missing is that currently, batteries are built in to the structure of the vehicle. To do otherwise would necessarily reduce the size of the battery significantly, as now the battery needs to fit in a convenient to remove location, and all the parts necessary to enable insertion/removal of the battery would take up space. Not to mention that the batteries are wickedly heavy, too heavy to be lifted by a single person, so there would need to be a machine to swap them, which takes up real estate at the gas station, and just generally complicates things.

Maybe there will be swappable batteries eventually, or one part of the battery will be swappable, but as far as I understand thats not coming soon.
Show HN: Record your CSS usage on your website - remove unwanted CSS
This is a follow up to: http://news.ycombinator.com/item?id=5095516 regarding CSS optimisation.

The common request/theme in these comments was the ability to 'record' your CSS usage on your website as you used it, thus capturing all the CSS selectors (i.e. on a dynamic website).

Turns out this functionality is actually inside Chrome Developer Tools; "CSS Selector Profile".

The profiler seems to be designed to record how much work each CSS selector takes - but I've noticed that it actually 'records' your usage (you press start + stop) - and shows you how many times each selector was called during your usage.

i.e. some selectors were used 100 times, other selectors 0 times.

So now you can look at your CSS across your whole dynamic site - and remove selectors that are never used.
Exactly. The alternative is to require your customers to pass a DiffEq test before you sell them the car.
PayPal is multi-currency so perhaps it's possible to convert to a currency that will work.

I guess the point is, moving money around is not that easy, country borders make it significantly more difficult, PayPal freezes typically make sense (such as in this case) but PayPal is made up of people, many of whom might be willing and able to help you out.
You can get a social security number with you F1 or J1 visa.... I just did when I got my MSc. For example, if you work as a T.A. or R.A. you get a SSN.

He didn't started a company anyway. Selling old clothes and old toys in ebay doesn't make us a company, does it ?! What if we sold $200k worth in old toys ?! Paypal would take our money anyway...
Yeah but this is the scenario many companies face. It's not like there are THAT many companies with Billions in multiple revenue channels that aren't effectively umbrella corporations.

Google funnels most of their diverse online product set back into the primary money generator. I'm sure we'll see less of that in the future as there are so many people that have pointed this out it's almost tiring.

Having to put a propane heater into a shiny, high-tech electric car would be a marketing disaster: it would emphasize that battery capacity was something that drivers have to worry about under normal driving conditions. Plus, Tesla could no longer claim that their car had zero CO2 emissions.

Paypal are bastards, as simple as that.
I actually think the major thing missing here ia not swapping out the entire pack (although that would probably be more time efficient), but having some sort of emergency pack to get you that extra 5 or 10 miles you need to a charging station.
There is a law against participating in a business. The only way you are allowed to earn an income is if it is an approved on-campus job.
