They could practice stalling via jumps from an airplane to get a feel for the limits of a wingsuit. As the article states, wingsuiting should be the last stage in a progression which begins with skydiving, not the first. Beginners are taking shortcuts on the road to necessary experience.

The possibility of stalling should be obvious to anyone who has flown a kite or thrown a paper airplane. Inexperienced wingsuiters just seem to forget it. They are lured into trying to achieve the illusion of lift whereas an experienced practitioner would maintain speed.

That's an incredibly complex ethical decision for the brand. I think Clif is doing the right thing by pulling out of sports with very low margins for error.

That's interesting, I have similar experience. Maybe that just means we didn't learn the original material well enough?
In 1933 anti-semitism was a respectable political position. Hitler didn't have to hide the fact that he was anti-semitic. He explicitly ran on anti-semitism, and the German people voted for him because of his anti-semitism, not in spite of it. It was only when faced with the reality of what it actually means to carry this moral position to its logical conclusion that the world finally recoiled in horror and said, "Never again." That is what it means to say, "It's 2016." It means that we live in a world where someone actually did this experiment in the not-so-distant past. It didn't end well. And so we should be able to see that doing the same experiment again with Muslims standing in for Jews might not be such a hot idea.
True. I would say that the equipment has been really good for a long time now. I can't think of a fatality in the last 10 years or so that was caused by gear failure, although there have been packing errors.

The sport is very unforgiving of mistakes, obviously. Only today I saw a video of someone about to do a rollover without their legstraps on. Luckily the same guy as in your video noticed and yelled at him to stop. Fatality avoided.

Most of the recent spate of deaths though don't follow any particular pattern apart from the wingsuit being the common factor.
tl;dr: because they're now doing it in wingsuits.

The reason HN still managed to do good without tags is the culture itself.The hacker culture is not limited to any domain (tag). What stimulates a human brain to think becomes part of HN discussion.
WW3 UFO CAUGHT ON VIDEO OVER US CREATED WAR ZONE
This economic plan - pegging to the US dollar - led to large current account deficits.

The only reason why this "worked" was because following the plan imposed by foreign investors (i.e. the IMF) meant that they could secure foreign currency.

This still meant that they were basically swapping hyperinflation for racking up a huge external debt instead, and they were essentially more dependent upon foreign investors. The fact that this 'worked' and didn't lead to disaster was probably due to the fact that oil prices kept creeping up. Currency pegging was used in Venezuela too and that story ended in disaster.

In terms of poverty reduction, Lula's Bolsa Familia program was more effective than this at actually helping people, but foreign investors love the story about how "Brazil was made safe again for foreign investors".
I was a little surprised by that quote since this is something you learn in skydiving class, and everyone's getting basic skydiving certification in order to start BASE. You learn on your first day that if you hug the beach ball, you will flip and fall with your back down. The easy to remember analogy is a falling leaf -- leaves always fall concave (edit I mean convex) side down; cupping the air is completely unstable.

Anyway, you're right, it's an important piece, and I'm sure the hugging the beach ball thing might become an instinct response that overrides your training and happens very quickly when it becomes obvious that you're going to collide in 0.5 seconds. But, the article also immediately follows that with 'but that doesn't explain why the best flyers are dying'.

The singular reason people are dying is because they're pushing the boundaries of proximity flying, not because beginners are accidentally stalling once they're too close.
This has never happened to me. Is it possible it's nothing to do with being in central London but due to dust and debris in the tube system? The amount of stuff that gets blown around in the air in the deep level lines is blinding if you don't look away as a train approaches.
No need for tax lawyers. Money is just drawn out via franchise fees etc to be taxed elsewhere.
Your "proofs" simply assumes that 0.999... is a notation denoting 1, without examining the underpinnings which might legitimize that.

9.999.. - 0.999 is 9 no matter how we define .999... just as long as two or more occurrences of the 0.999... notation all denote the same entity, and we understand that the syntax 9.999... is 9 + 0.999...

For example, if we define 0.999... as "rubber duck" then 9.999... stands for 9 + "rubber duck", and 9.999... - 0.999... stands for 9 + "rubber duck" - "rubber duck" = 9.

The vast majority of orders (over 90%) come from Salzburg, Austria, although in a few occasions I even had same day shipping, those came from somewhere even closer.
Job offer at amazon canada
Hi there,

I've just git an offer to vancouver, canada. it is 125k CAD base + 17k CAD signing bonus 1 yr, plus 15k CAD second year + 118 stocks + relocation. This is for LVL5 (SDE 2). How good is the offer? Is it affordable to live in Vancouver with two children for that money (renting)?

I am from Europe, planning to relocate later to the us. Thanks

Show HN: HelpTerence, a social media experiment with a Twitter Bot
Focus and good moderation. It's better to think of HN as a mid-sized, well moderated subreddit, than a comparison to Reddit as a website. You'll see that as subreddit grow bigger and become "default", content quality often slides. This can often be stemmed by good moderation, but they only have so much power with the limited tools Reddit gives them.

HN's moderators are also the programmers of this website, so if they need a new tool? Bam, new tool.
Getting angry about anything, even your friends dying, is no longer allowed.

I sometimes go to http://voat.Co and poke around when I want to remember what the Internet used to be like. It's one of the few forums that doesn't have a blanket ban on expressing anger.

What's funny is that it's very Californian to never express anger. East coast culture is more direct. People will say to each other that they don't like something the other person did or are upset or angry at the other person. On the west coast, especially California, it's really important to be nice, so people will just cut off contact when they've been offended or decided they don't like someone rather than confront them. Those California social values seem to have migrated online.
I doubt it. Easily 10X the amount of spam and low quality posts HN would have to deal with.
Oddly enough, I never understood the epsilon-delta description of limits until I read David Foster Wallace's book on infinity. All through my degree in math I was taught about things without learning the historical context that created those things.

Can We Securely Store Card Data for Recurring Billing?
The net present value (NPV) of a customer is just the value today of all of all future revenue minus the cost today of all future expenses associated with them. The key is that it factors in a "discount rate" to account for the fact that cash in the future is worth less than cash today. So future cash is discounted by some ℅, compounded annually.

If a customer will pay $100, and it costs $90 to acquire them, without taking time into consideration it would look like $10 in profit. But if you have to spend the $90 today, and you only get the $100 in five years, they might not actually be a profitable customer. Conversely, if that same $100 revenue customer cost $105 to acquire, but they paid today and you only spent $105 to acquire them in five years they might actually be profitable (this scenario is probably less likely, but maybe if you are acquiring them through some channel where the costs are deferred for some reason).

Excel and a lot of other spreadsheets have a built in NPV function to make the calculation easier. You can simply give it the series of expected costs and revenue associated with the customer, and a discount rate (how much to discount future cash by, compounded annually) and it will give you the NPV.
Churn rate gives you average customer lifetime. You know how much they pay over that period, you ought to know your customer acquisition costs & the cost to service your customer base already if you have any kind of business head on at all. From these numbers you can calculate the value of an additional customer to your business. How much of that you’re willing to spend on marketing costs is up to you and your risk tolerance :)

The article states that stalling the suit is the primary reason for novice fatalities. As the sport becomes more popular, the majority of new practitioners will be novices making mistakes that an experienced jumper would not make.

This is a conjecture that desperately needs resolving with solid statistics and in-depth interviews.

This thread is not representative -- include engineers and professionals who may do math for a living. That's not everybody.

I think more empirical data is needed. If I go on the street or the math is comparable to 5th grade (at the very best) and in a business setting might bump up to 8th grade.

Does that preclude there being opportunities to need/use/benefit from math? No...

I think it just means there are opportunities that nobody is taking advantage of. Left open and collecting dust.
Only few people in finance really "make it" - and it mostly consists of portfolio managers (quantitative or else). "Superstar economy" analogy discussed in this thread have very strong effect in finance.

Luck is also a huge factor. I know cases of International Olympiad gold Medalists, who didn't make it as portfolio managers. Do you really think you are smarter?

If you are mathematically inclined software engineer, I would avoid finance unless you are immediately hired into the quantitative role in the front office. In Silicon Valley you will get similar or better salary, more freedom, more respect and better culture. I worked on the both sides.

XP doesn't natively support hard disks with non-512-byte sectors, leading to performance degradation (and possibly more wear?) on modern, higher-capacity hard drives which use 4096-byte sectors and have to emulate 512-byte sectors for Windows XP's sake.
It might be better than no sensors.
Vista and Windows 8 are what you get when the goals are set high, but not enough time is given to achieve them.
It's saddening the number of national economies that have been destroyed by politicians who don't understand economic fundamentals. When it comes to most matters like the military for the example, we trust our generals to organise and manage the Armed Forces as per their best judgement. And yet, when it comes to economic policy, we persist in thinking that it should be implemented by career politicians and popular opinion. As long as that doesn't change, I think we're doomed to see endless repeats of such rookie mistakes.
All these agreements are worthless. The question is, will there be a technology that prevents earth from heating up from burning fossil fuels.
I think most everyone watching the sport has been predicting a higher death rate, it's quite unsurprising, and why is not a mystery -- but this article was very well done IMO. It's clear from the explosion of wingsuit videos that the risk factor is dramatically higher, and that the videos themselves are going to be a factor in luring more people with less experience to try it. It looks amazingly fun, and very tempting if you're already or willing to start skydiving.

I personally feel very lucky to have passed through the skydiving phase of my life alive. Every jumper I knew personally except one is dead now. Some died in the most crazy unlikely ways, and a bunch of them died together in a plane crash after a weekend boogie. Skydiving is super dangerous, and BASE is even more dangerous, and wingsuit BASE trying to buzz the ground within inches -- How are so many BASE jumpers NOT dying??

Dunno. With Linux being a loosely coupled collection of parts, it is quite possible to upgrade the kernel without disrupting userspace.

And with Apple, you are dealing with one vendor support a small set of their own products. The only way to get into this issue would be with a hackintosh rig.
One of the commenters to the original article talks about this phenomenon specifically. Each math course you took taught you some ideas or techniques, but those techniques weren't really learned until you used them in the next course. For example, you didn't learn algebra well until you used it in calc 1; calc 1 skills are really cemented in difeq.

I'd suspect there's a disconnect between the group selling/providing the tools, and the group using them.

A webkit 0day could've been delivered via a watering-hole attack or something even just a tiny bit more sophisticated (compromise a trusted contacts social media account, send the link from there) and succeeded.

Whoever put the effort/time/money into developing the exploit chain is likely pissed off it got burnt via such an amateur delivery.
I'm going to quibble a bit, hopefully not in an annoying fashion.

The distinction is that the tax system does not give a deduction to individuals who are spending their money on personal "consumptive" reasons. By and large, the system does give deductions for expenses incurred for business.

In this light, the double taxation of corporations is unusual. Clearly, the dividends are to pay back investors, just as interest is part of paying back lenders. But interest is deductible; why not dividends? Many theories have been advanced to justify this double tax, but none have won wide support among scholars.

(Interestingly, in your example, what probably would happen is that Bob would essentially be the effective managing partner of a general partnership. So we would be under partnership tax rules.)

A last quibble: partnership tax actually taxes partners even while the income is held by the partnership. (Well, generally; there apparently are some odd trust schemes that sort of avoid this.) in general, Partnerships must allocate the income to the partners, who bear the burden of tax. Then, they must later distribute the income in accord with how they've allocated it.
I had a philosophy professor who believed evolution was 'just a theory', and routinely dismissed it. I don't think she was religious either. Then again, I had another philosophy teacher who taught logic, which is the most pure use of right/wrong that I can think of.
This is probably true for many programmers today, but machine learning is hot and that definitely requires heavy math, so I wouldn't bet on it remaining true.

Allocating every country the same per-capita quota of emission would be both fair, _and_ would save the planet, if the quota is low enough and exchangeable. But that would imply that we, the high per-capita polluting countries would pay money to poor countries like India to buy their excess quota.
People were used to inflation, and prices would go up as a regular practice.

Indexing prices using URV, all prices would increase in a regular pace, all prices together, and inflationary pressure would lose the irregularity (no more uneven increases, that anyone would compensate in the next step).

After a while, just rename this fake money to "real", and you have Brazil with its long-surviving money.

This is interesting because Starbucks doesnt franchise in the US [0]. They do have one alternative that's what you see in most airports and in coffee shops with the sign "proudly serving Starbucks coffee", for example Barnes & Noble cafes are this style. These third party stores, for instance, cannot accept payment from the Starbucks mobile app and offer only a subset of drinks. I'm not sure what the term for this is but it is some kind of licensing deal.

> But new x86 chips are backward compatible.

Broadly-speaking, yes, but older OSes may not support newer CPU and other hardware features, and at some point those features become essential to working at all. Plus, CPUs actually do drop features sometimes.

In the case of Skylake, Windows 7 doesn't support xHCI, the new USB controller interface. Without USB, you won't have much luck doing anything.
This is why you can't leave culture to corporations. It is very difficult for them to resist the short-term calculus of "removing every post that is slightly negative to the brand", because Facebook doesn't want to be associated with rage or anger or anything negative. But what's left isn't culture anymore.

I think they've still got at least another year or two before this becomes really obvious to the mainstream, but Facebook is definitely headed in a dangerous direction right now. Not to culture; it will survive. It can't be killed even if you want to kill it. (You can hurt it, but not kill it.) But to Facebook. The appeal of a space where you can't say anything that is negative that might be associated with Facebook isn't great to start with, but when you realize that it's Facebook that has sole control over what it considers negative you also get that helpless feeling. Most people aren't going to analyze this... they're just going to realize they don't feel good when they use Facebook, either because their posts are getting censored or because they are subconsciously self-censoring, and operant conditioning will lead them away.

It's becoming more obvious every week that Facebook's instinctive reaction to everything is to control it with a heavy hand.
Any time you have an entity that's low on capital but high in potential, it's bound to attract outside investors, which is in turn bound to produce current account deficits. This isn't necessarily a bad thing. Having outside investors provide the capital needed to ramp up your operations, can be a huge win-win for both sides. In fact, this is exactly how most successful startups got to where they are today.

In contrast, I can't think of a single country with hyper-inflation that had a successful economy.
