This! The empty function is the function whose graph is the empty set. When you stop thinking of functions as symbolic expressions and make friends with the empty set, it's all clear as crystal. The empty set has perplexed a lot of people over the ages, so it's unsurprising that 0^0 prompts puzzlement. But with the benefit of modern hindsight, there's really no reason to stay confused. Set theory in the large is still a great mystery but we got the empty set well figured out by now.

The article mentioned some interesting data points, but it doesn't do anything more than that. Correlation does not imply causation, and all that. For example, what is their definition of 'religious'? What other demographic differences could explain this?

I'm not saying that the conclusion is necessarily wrong, but I think that a bit more scientific rigor would be useful.

Jobs WAS perceived as absolutely absurd during his first stint at Apple. It's a big part of why the board kicked him out in 1985.

If he didn't have a track record of success on the iPod, iPhone, and iPad, his demanding and aggressive personality wouldn't go over as well.

Most people with his type of personality come off as extremely abrasive more than they come off as "genius".
7 products Steve Jobs got wrong
You misunderstand, it isn't selfish to want it for yourself, but it is selfish to keep someone else alive in a vegetative state. It is so easy to choose 'life' as the correct and right thing when in fact 'death' is the natural and moral thing. Society needs to think about their end of life plans. If your plan is to be fed through IVs, have a foley, breath through a machine, have a butt tube, and foley catheter in for the last 10 years of your life be my guest. Just please don't use any of my tax dollars for that! The sad thing is most people don't chose this for themselves, instead they have a stroke or suffer another handicap and while they are unable to make decisions (probably unable forever) the family chants 'do everything you can'! Medicine can do a lot, but mostly at the end of life it just prolongs misery.

I routinely ask patients their 'code status' and articles like this give them false hope and false belief. Instead of: "do you want us to do cpr if your heart stops and/or intubate" ... I should be saying, "do you want your last dying moment to have someone beating on your chest breaking all your ribs while another person shoves a tube down your throat as you get pumped full of drugs."

You will never forget the first time you push on ribs and feel the crunch, watching the half-dead eyes look up at you as they live their last moments, and wondering if they are feeling their veins burn with drugs being pumped in.

Never mind that the article makes it sound like resuscitation efforts are grand. They aren't at all. The statistics are dismal.

Oh ACLS drugs? Yea, they don't really work to well... even as far back as 1998.. there are newer studies showing that ACLS training is helpful, but the actual drugs make little to no difference.

Gamers love the concept of digital distribution but not the way Steam does it.

Where do you think Steam fails in this respect? Is it simply the lack of a rental option?

When I encounter limits that directly affect me, it's usually due to restrictions insisted upon by some brain dead publisher, but not by Valve.

So I (as a steam "fan" [not fanboy]) are really interested in where you think the service lets you down.

> For example, how to handle versioning (compatibility between client and api)

Whatever you do, please have a distinguishable api versioning.

i.e:

example.com/api/1.0/

or:

api.example.com/1.0/

In this way you can add other versions very easily (api.example.com/2.0/) and avoid clinet-side confusions.
Many great ideas are obvious in hindsight. If it was so obvious why had nobody done it?

Would you say, "Oh Amazon? Whatever they're not doing anything new. They're just selling shit except their store is on the web. Big deal, that's not innovative just because they're doing it on a computer."

My mom owned a Nokia slider back in the late 1900s, but the model preceding that one. If Nokia had kept making top-end phones like those were in their day I would probably still be buying Nokias. I swore by them. You could drop them, throw them, soak them, anything. Dry it out, take it apart, and it was fine. About 7-10 years ago, with a lot of their models, the worst case scenario was you bought a new case. And the UI was actually quite good, definitely superior to other phones of the time (that I tried anyway).

I had a Nokia phone from the late 1900s until 2008. The last Nokia product I bought is the n810 and it was not very good. I loved the idea but the execution was poor (and I got the 3rd version). I rarely used it and then never used it once I got an iPhone. The iPhone 3GS was a better browser than the Internet Tablet, better GPS (it's using other location data but I don't care, it's still better), and happened to also be my mp3 player and phone.

It's sad to see Nokia today, I really hope they can turn around but I have less hope for Nokia than I do for webOS :(

> Technically, 0^0 is an indeterminate form and has no specific solution.

Precisely, as this is the true mathematician answer: "it depends where 0^0 comes from".

As a f(x,y): RxR->R function, come from the top of the R² plane and 0^0 is 0 but come from the right side and it's 1. Limits and extension by continuity give us this easily enough for fh:x->x^0 and fv:y->0^y.

Writing this I asked myself, what if we came from some funky other path, like the diagonal, or a curve?

h: R->RxR, x->(x, 0) defines "coming from the top", and foh = fh

v: R->RxR, x->(0, y) defines "coming from the top", and fov = fv

d: R->RxR, x->(x, x) defines coming along the diagonal, where things could get interesting.

s: R->RxR, t->(e^(at)sin(t), e^(at)cos(t)) defines coming along a log spiral whose tangent at t=0 is vertical, so fos looks like fun around t=0.

Now what happens if we build a path function p: RxR->RxR, (t, z)->? that endlessly approaches v when z->0? the log spiral with z=1/a as a parameter is a possible one. With such a p function, what does lim fop(x) when x->0 (which is a function of z) look like when subsequently z->0?

Damn. It was supposed to be a two-line comment.

Collapse does spend a fair amount of time discussing Iceland precisely because the society there did not collapse in the same way as the similar society in Greenland even though they had a serious ecological disaster caused by the application of farming techniques suitable for the heavy soils of Scandinavia and the British Isles to the light volcanic soils of Iceland.

Arguably Collapse is just as much about societies that avoid collapse as it is about those that did disappear.
Who cares if Iceland is a member or almost a member. That's not the point of the article. Can we discuss the main point please, that is a country's population refusing to bail out the criminals of the financial sector.

Yes I could look it up beforehand, but why make me take three actions (look for free space on device, look for total space required, order to copy) when one would be sufficient? The computer should do the tedious tasks and let me decide.

Your comment was better than the original post.
My two favorite Steve quotes both came during a talk with some interns one summer (paraphrasing from memory):

-----

Intern: "Where do you see Apple in 5 years? 10 years?"

Steve: "I don't know. I'm too focused on where Apple is going tomorrow...and I think anyone that does tell you they know where their company will be in 5 years is lying, or doesn't have enough to worry about now."

(It was clear that Steve saw Apple's roadmap as a continuous progression from the present, rather than a plotted course to some arbitrary goal. That's an attitude that I've found has served me very well...)

-----

Intern: "What are your dreams?"

Steve: "To not be asked questions like that...next"

It's a pity that there's no ruby native way of adding another encoding in Ruby 1.9, it's all down on the C level. Recently I needed to work with the GSM-7 encoding, and while I was tempted to try to add a patch to ruby for including it, I figured it was too marginal to warrant acceptance of the patch.

It's a rapid development tool for front-end development. If I'm reading the documation correctly, I think it's based on the MVC architecture.

Sure, you could make your backend in plain Ruby, but if you learn to use Rails you can do things quicker.

Sure, you could make your frontend in plain JavaScript, but if you learn to use batman.js you can do things quicker.
To continue on this thread, I once heard Steve describe it this way:

"When I returned to Apple, I went to every engineering team and fired all the managers. Then, I went to the smartest engineer on each team and told them they were going to be the new manager. Of course, being the smartest engineers, they all immediately said, 'No'! So I told them, 'Look, either you're going to be the new manager, or I'll go hire someone like your old manager.' After that, every one of them agreed to take the position."
I also use knockout.js for a project and batman.js looks like it has some similarities but it seems to be filling some holes that knockout.js leaves you to fill your self.
And while we're taking requests, one in a similar style on type inference would be great too.
Indeed. Still fancy a LeCroy - perhaps in about 30 years :)

IPhone 5 to be released this October
You go right ahead, but I'm not going to discuss the article's main point until I've had time to read up on the relevant background from other sources. Facts are not ornamental adjoints to an analysis but the very stuff out of which it is made. Besides, there were other inaccuracies. The article claimed that the British and Dutch governments threatened to freeze assets of Icelanders when it seems the only target was assets directly owned by Landsbanki. That's still extraordinary, especially seeing it was prosecuted under the guise of anti-terror, but it is very different in fact and substance from what was claimed.
Indeed, my understanding is that the only reason that Iceland wasn't a member of the EU before was that they didn't want to be until recently.

For example, compare:

http://en.wikipedia.org/wiki/Accession_of_Iceland_to_the_Eur...

and

http://en.wikipedia.org/wiki/Accession_of_Turkey_to_the_Euro...

Personally, I would love to see Turkey in the EU but they have got a lot more work to do than somewhere like Iceland.
I can always tell how big the media thinks a story is by how many unusual places I see it reported. As I type this, "Apple's Steve Jobs steps down" is in the headlines box on ESPN.com right between the little league world series and a story about Tom Brady.

If I remember correctly, the Lisa was someone else's project and Steve Jobs stole developers away from the Lisa project to build the Macintosh.

Let's not forget the iPod Hi-Fi though.

Yes, in a way. But I don't think in this case it matters that much. It's like saying: hey, look at that politician, he smoked weed in college, now this is supposed to undermine his overall credibility. Who cares.

This is totally not related to your question, and I am sorry for that, but I really think your tool is something very interesting. The concept is really cool, however, I think the writing and the imagery need to be worked on a bit; not from the perspective of SEO but from the perspective of getting the message across. Right now, in my opinion, the message is a bit wayward and not getting across to the reader clearly. Case in point:

I need ideas for my next weekend project to polish my python skills. Please suggest me some. Please note:

1. I will be developing it in either python/django or on google app engine. This for polishing my python skills.

2. The idea should be innovative and useful, not necessarily profitable.

3. It can be anything, from a web application to a python module. Anything that is useful but interesting.

4. I will release the code as open source and host in on github.

5. If you wanna get prototype of your idea developed, I'm fine with it too. I will do it free of cost but I can't promise timely delivery.

I'll say only 3-4 of them were "wrong".

The NeXT didn't sell well, but if Steve didn't started it, I'm not sure if he would even be offered a chance to lead Apple. By the time the board realized they needed Steve back, either Apple would have been bankrupted already, or Steve would be doing something else instead of NeXT, which means he may not want to drop that to go back to Apple.

The ROKR was one of the most successful business plan executed by Steve. Apple got to know the phone biz and people get to taste how bad a non-Apple iTunes phone can be. Calling it a Apple product is absurd, it is 20% Apple at best.

The AppleTV may be a small pie in Apple's revenue today. But it won't stay that way for long. And is probably one of the most (if not the most) successful non-subscription TV box on the market even today.

Yea, the hockey puck was really bad, but is such a small product even worth mentioning?

Peak Games from Istanbul: 7.5M in funding, 2M daily active users
I've never been to this website before, but reading the article it seems like they have a chip on their shoulder about global warming:

"A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point." So wrote the celebrated Stanford University psychologist Leon Festinger (PDF), in a passage that might have been referring to climate change denial—the persistent rejection, on the part of so many Americans today, of what we know about global warming and its human causes.

That seems to be a strange example to use, since Climate Change can probably be described as "The most contentious argument about a totally ambiguous data set in the history of mankind". It polarizes people so strongly by nature of the fact that the same data can reasonably be read to support either conclusion. By grouping people who the author considers to be on the other side of that issue with people who ruined their lives chasing aliens, it just reads like they're trying to justify calling the opposition in their little fight crazy.
