NeXT was founded in 1985 for the purpose of creating a good workstation for the higher education market. By then, SunOS 2.0 was out, Ultrix was out, and 4.3BSD was under development. It wasn't even until mid-1986 that NeXT decided to make their own OS, and that was around the time that 4.3BSD and AIX were released. With Apple's technology off-limits, I'd say NeXT was following the herd when they decided to build off BSD.
How about iTunes? The App store? The iPad? I can go build some shit product and ship it first, but without a reliable customer base, there is no market. So yes, I think it is fair to say Apple has created new markets. Prior to 2007 the Motorola Razr was the most popular phone on the market. Enough said.
Nasdaq-100 Futures Retreat After Jobs Resigns
Do visionaries "rise in the ranks"? Did Steve?
He's describing, at most, a two month stretch of time. Your response is entirely true, of course, but you're not speaking in the same scope. I think all John is saying here is that it's not going to collapse before our eyes, and that established teams, corporate cultures, and philosophies take time to erode.
I don't understand your logic. The GPL ensures that the software is free for you, your children and their children to modify as they please.
A chronology of Steve Jobs at Apple
Unfortunately its the end result taht matters.
I agree, but I feel like I have seen too many job postings where the HR person posting just decided to tack on extra years for a requirement. I understand that they are looking for the best person they can possibly get for a position, but it is entertaining when the added years pre-date the technology's release.
Ask HN: How to give your iOS app a fighting chance? 
Hi guys,

I'm slowly working on my first iphone app in my spare time.

Watching how the app store works and watching lots of apps appear briefly in the new releases before plummeting into the abyss leads me to this question...

Are there certain things you MUST now do if your app is to stand any chance of gaining enough users to get into the rankings and keep on climbing?

On launch day do you NEED an email list of eager people ready to go and buy your app and write reviews?

Is there a secret giant conspiracy amongst cartels of app developers of I pat your back, you pat mine that you NEED to be participating in?

What things MUST you do to stand a chance?

And what things spell certain doom?

It seems pretty unforgiving out there.

Cheers!
A lot of companies have armies of talented engineers and designers but their products still suck compared to Apple because they don't have what Apple has: an uncompromising singular vision and putting design first.

Other companies with plenty of design talent are also afflicted with small-minded management who are only concerned about their pet deal of the moment, obsessing over mimicking their competitors, and too quick to throw away entire product lines that don't hit homeruns on the first release.

Dear Steve: Get well, Maestro.
Violating relativity by breaking equivalence
Here comes the inventor hipsters.
I didn't realize there was a "right of first sale" in trademark law (obviously I'm not a lawyer) but what Wikipedia says about it is this:

> With reference to trade in tangible merchandise, such as the retailing of goods bearing a trademark, the "first sale" rule serves to immunize a reseller from infringement liability. Such protection to the reseller extends to the point where said goods have not been altered so as to be materially different from those originating from the trademark owner.

It seems to me that removing coupons from the box is "altering goods so as to be materially different from those originating from the trademark owner".
There was an interesting article a while back about some of the shady practices of Group Purchasing Organisations (who negotiate with pharma/equipment suppliers for cheaper rates)

> Irrational numbers are probably a bad example of what you're talking about.

No, they're the perfect example and you're observation about the unit square is glib.

Trying to reason about the diagonal of the unit square basically destroyed the Pythagorean world view of integers as the fundamental building blocks of reality.

If mathematical entities are simply discovered and that-is-that, then why did it take nearly two millenia after this observation for western math to accept irrationals as numbers?

From M. Stifel, 1544:

"Now, that cannot be called a true number which is of such a nature that it lacks precision. Therefore, just as an infinite number is not a number, so an irrational number is not a true number, but lies hidden in a kind of cloud of infinity"
I completely agree. I will gladly bet $100 on that Apple, without Steve Jobs' help, will create a new product in the coming decade that'll revolutionize (or even create) a market completely like they've done with the iPod, iPhone, iPad and many other products.

Steve Jobs may not be the CEO anymore, but his spirit and philosophy will be alive and well in Apple for a long time to come, no matter what happens with him personally.
Perhaps not, but that doesn't necessarily imply that the use of CoffeeScript-only examples was a calculated move to reach the audience they wanted instead of whatever came to mind first. It's worth at least reminding them that JS examples might be more useful to more people and letting them decide consciously whether they care.
Completely agree. Why is this militant fanboy's posts always front page? It's overly biased dribble every time.
10 Unusual Things I didn't Know About Steve Jobs
No amount of riches would have saved the life of Prince Leopold, Duke of Albany. At the time we didn't have the medical technology to treat hemophilia. Likewise, if the technology existed to make Steve Jobs healthy, it would have been used by now.
Jony Ive is still there right? Look at how he's progressed from the toilet seat portable, to the Pismos, to the Luxo iMac, to the white iMac, to the unibodies.

Sure Steve was there, praising and berating, but I doubt Steve himself would have come up with even this aluminum slab keyboard I'm typing on right now, though I'm sure he loved it when Ive and his team brought it in.

Apple has likely had long enough to assemble people that share the vision, that Apple design should evolve towards ever greater things. The iPhone was a huge lesson, that even now, and it's always now, there's room to shake something up with better design, vision and software.
It's not something that can be quantified, though. The problem is that meaning is an entirely subjective phenomenon, so when we talk about trying to save people who are more likely to live, we make the assumption that long life is the correct metric to use. More than that, we assume that there is a correct metric to use in the first place. As a concrete counter-point, what if the person saved will have a terrible life to look forward to? What if it's an abused wife or a (unknown to the doctors) drug addict? What if the person with the lower chance of survival is a parent or Mother Therasa? What if the person with the better survival rate doesn't want to live and will commit suicide shortly?

The problem with applying linear mathematics to human issues is that it's a gross oversimplification of a complex problem. Couple that with the relative weight of values (i.e. every person placing a different value on life) and it's clear that rather than being a more objective measure, it is in fact firmly grounded in subjectivity. I think that the objective illusion only serves to calm the conscience. A more objective and fair way of doing this, which also calms the conscience, would be to flip a coin.

The other issue is that the line of thinking you have described is the same one used to justify horrendous actions. Sacrificing someone who is seemingly less deserving of effort (again, by our completely subjective criteria) for someone more deserving is the logic used to justify locking people up in prisons, burning witches, gassing Jews, it's all the same - those "less deserving" are sacrificed for those who are "more deserving". And all that with a subjective metric.

I think that the root cause of this irrationality is that even the most rational people tend to miss the fact that perfecting one's logic is not enough. After that point, assumptions are everything. Logic is merely a tool for transforming one set of assumptions into another. If you use shit as the input, you'll get an equivalent output.

I'm a mathematician as well

As am I, by training if not by profession. As is lotharbot. You're in a thread full of mathematicians. :)

Which is what I would expect on this site, actually. I'm always timid making technical claims here unless I'm sure I'm correct; it seems to be a place frequented by arbitrarily large fish.

To answer your question, if 0^0 = 1 is _the_ answer in discrete setting, and it's _an_ answer in continuous setting, why don't we just agree that 0^0 = 1 and stop creating confusing situation where sometimes it's defined and sometimes it's not.

I'm not persuaded it is always the answer. I think the fact that it is an indeterminate form in limits is a forceful enough demonstration of that. It all depends on context. If I came across a 0^0 in, say, an engineering context, my first instinct would be to check whether the formula was defined in that case, not to just assume that 1 would work.

I mean, it's like 1/0. If you're working in R, that's simply illegal. If you're working in R*, it's the infinite point. If you're taking a limit, it means "unbounded". If you're working in my favorite field, the hyperreals, it could be any number of flavors of infinity depending on the flavor of zero it was.

It would be foolhardy to try to define the symbol; without a context to supply some sort of sense, it is nonsense. And that is how I feel about 0^0 as well.
A large part of Apple's success is the NeXT heritage in the form of NextStep that was the sapling that has grown into Tiger, Leopard, Snow Leopard and now Lion.
> They could pull a hunter off the street and ask what they would define as 'Deus Ex', the punter might say the game.

I think that traditionally it's the trademark owner who gets to define what their trademark is allowed to be applied to, not a "hunter off the street." (Did you mean "punter"?) This sometimes has deleterious effects — for example, Saran Wrap no longer contains any Saran, and Kaopectate in the US no longer consists of kaolinite and pectin — but by and large it's a sensible policy, in light of the information asymmetry between consumers and producers that makes trademark law a reasonable bargain in the first place.

("Information asymmetry"? I mean, if you knew how to make flawless replacement cylinder heads for your Ferrari, you'd likely make them yourself instead of buying them from Ferrari; and if you knew how to identify flawless cylinder heads, you wouldn't need the Ferrari trademark to ensure that the ones you bought were flawless. The reason the trademark benefits you as a consumer, or for that matter Ferrari as a producer, is that it allows you to delegate that decision to Ferrari's engineers, machinists, etc., even when you're buying the part through a reseller; and then Ferrari can charge a premium for their reputation.)
i just can't get the words of dennis hopper from apocalypse now out of my head: when he dies, it dies, man.
And the cleverest student turns out to be right, given the convention asserted by the mathematician. If 0⁰ were 0, or indeterminate, then the limit wouldn't exist and, therefore, L'Hôpital's Rule wouldn't apply. But given that it's 1, the limit does exist, and all is well until Zermelo-Fraenkel is proven inconsistent.
Ask HN: How do you hack body language?
I have a unconfident walk. I have a good posture, etc but every moment that I walk I am uber self-conscious trying to control each and every movement of my body, and yet it doesn't just feel right.

I have tried to look at movies and imitate actors, and just read this story on HN which made me realize that I could use some more guidance in this sphere.

You can pretty much conquer the world with a confident walk, a well-thought-out outfit and confident demeanor. We teach people how to treat us and when you show people that you're a force to be reckoned with, they'll believe you.

Thanks.
It's nothing to do with how the Mac ranks in Apple's priorities. Apple security has been a joke, compared to Windows, for a very long time.
To the extent that people have to do a 12 year study program to do first aid or put on a band-aid, I'm suggesting that people should do a 12 year study program to put up their volleyball club's website or turn on their computers.
This explanation works pretty well on adults: Just include the multiplicative identity (1) in the expansion.

3^3 = 3*3*3*1 = 27
3^2 = 3*3*1 = 9
3^1 = 3*1 = 3
3^0 = 1 = 1

and likewise:

0^3 = 0*0*0*1 = 0
0^2 = 0*0*1 = 0
0^1 = 0*1 = 0
0^0 = 1 = 1

I haven't yet tried this on an actual 10 year old, though.
CEO or not, this guy is capable of giving you some serious advice that can change your life. Such quality products must come from people with good intentions towards change.
any attempt at accessible (that is, text based) content will make it wide open to automated solving and ruin the whole point.

Maybe an audio snippet could be used as an alternative, although actually creating the audio (unless it's done with text to speech methods at the server/creation time) is going to significantly bump up the cost of creating the advert.
Fractals have a property called self-similarity, where "a self-similar object is exactly or approximately similar to a part of itself."

John is saying that Apple's products have an "Apple-ness", as does each app on each product, each feature within each app, etc.

He is suggesting that the zen-like simplicity of Apple can be found at many different levels of the organization. I don't think it's overly biased dribble... it's an eloquent point that Apple Inc. is a culture (cult?) with a clearly identifiable philosophy that permeates every element of the org.
I'd say he's going for being contrarian rather than PC. It didn't sound sexist to me, likely because the CEO was also female.
I'd say it would be closer to the scientist giving the speech language in West Frisian to a group that's composed of 90% English speakers.

Or maybe more accurately a speech in modern English to a group of early modern English speakers.
Gruber is an apple dick-rider of the highest caliber. No wonder he would come up with some trite BS like this.
Definitely. If done in the same general style as your lambda calculus one I think it would be a great resource.
A precondition of L'Hôpital's Rule is that the limit in question exists. So: Prove that the limit exists, and then you can bust out L'Hôpital's Rule to prove that it's 1.
I can only feel a bit of sadness not just from his resignation, but from the health circumstances that are likely behind this.

I have to take my hat off to Mr. Jobs. Though there is much I disagree with him on (and personally, I'm not much of an Apple fan or consumer), he's one of the most amazing, talented and driven people I've ever seen.

He's brought a unique and masterful skill to the art of selling, vertical integration, acquisitions and consumer electronics. And I mean art. Vertical integration was never something I thought I'd appreciate on an aesthetic level until I saw the level that Jobs has raised that form to time and again. The NeXT computer production line was divine.

I think he's learned tremendously from what happened to Apple the last time he left and has spent extraordinary effort to ensure a smooth and capable team takes over. I can only guess that this might be happening after seeing the capability that the current team has executed with these past few months.

I want Apple in the fight, they continuously raise the bar in the industry and literally make it great to be a consumer, even if you don't buy their stuff yourself.

Kudos to Jobs for a job well done, and I wish him the best in health.
Looks like a good time to pick up some Apple stock after the idiots are done selling. Sept annoucements and Xmas quarter sales. HP's annoucements should help all the other PC maker's numbers in the 4th Qtr.
I think, and I might be going out on a limb here... that it was a joke.

Thanks!
How about if you were sick, but there was a serial killer who had a 98% of dying that, due to this sort of argument, was utilizing resources that would increase your chance of survival from 10% to 95%?

This argument fails to show that when it comes down to it, there's more than one person and their associated who get affected by the decision to invest those resources. The benefits to one person come at the expense of another in current healthcare situations.
Steve Jobs 2005 Stanford Commencement Speech
Not out of hucksterism, but because he really was that excited to share what he and his people had been working on.

I always viewed his pitches as amazing one-man performances, and buying whatever he was selling was just part of the cost of admission. Plus you ended up with a cool take home gift out of the exchange.

It never felt cheap, but often worked in areas that others would just turn into hopeless kitsch, yet somehow he kept it tasteful, meaningful and relevant. An absolute virtuoso of the sales performance.
It did not backfire. It should not be given up.

Ask HN: Which is the best name for a food web application
The current name of our food/recipe web application is:

deadgrandmacookies.com

As you might imagine, this name is rather polarizing. People either love it or hate it. We made sure to explain on the site why we chose this name, but it hasn't helped.

So do we keep this name (controversy can be good, right?). Or change it.

Here are some alternatives we've been tossing around:

food scraps, beetroots, cabbage tales, bitter pear, beef cookies, the broccoli chronicles,
food baby, grandmas cookies, my grandmas cookies, old grandma cookies

It is interesting that your compilers class targets the lambda calculus.

While we have a thorough curriculum on functional programming at CMU (and for one class I did write several compilers which took more complex languages and translated them to the lambda calculus and even more minimalistic languages like the SK (optionally I) combinator calculus, that class wasn't on compilers, it was "Principles of Programming Languages". It also covered type theory, implementing type inference, and so on.

Whereas our compilers class covers the sort of topics you would expect in a compiler targeting a real architecture: parsing/lexing, choosing intermediate languages, SSA form, optimizations, register allocation, code generation, and so on. We have a separate class which covers compiling higher order typed languages (SML in particular).

Our compilers class is also unusual (in ones I have seen) in that, instead of building a lexer, building a parser, doing translation, and so on for each stage, as separate projects, rather students build a whole compiler for each assignment. The language compiled gains more and more features: first control flow, then function calls, then memory operations (structs, arrays, heap-allocation).

Might I ask your thinking when choosing the lambda calculus as the basis for your compilers class?
I'm kind of a foodie, and our project manager is definitely a foodie. He runs this site that lists some great places to eat and drink if you're only in a city for a couple days. Here are his picks for Portland: http://noms.in/portland

I've seen very few places here that categorize themselves as gastropubs. There are a lot of breweries in Portland, and some of them have their own restaurants/pubs. But's that's a relatively small percentage of the diverse dining options here.
