How/where to begin learning mobile (app) development?
By way of background, I have an undergrad in CS and worked as a C++/Java programmer 10 years ago. I also have some experience with web development (LAMP). I'd like to get into mobile development (apps) for iOS, Android, etc. but quite frankly have no idea where to start.

If I choose a platform now (iOS or Android), am I essentially "stuck" in the platform or can I jump between the two? What do I need in terms of knowledge, skills, funds(?), to begin this learning process? The objective is to know enough to put together a team of devs, designers, to execute on B2B mobile apps.

You can do a lot better and explain yourself instead of name calling which it is. You are not pointing out a fact, you are stroking your ego.

I've wondered about this ever since reading Peter Cochrane's comments on it. When people want to concentrate on things, we hunch over them. Nobody reads a book at arms length, head up. Nobody knits or threads a needls at arms length, or does any kind of paperwork that way. Why do we compute that way?
I think there are established players in this space. Pronto Networks being one, but Boingo is the 800-lb gorilla.
I use both Disqus and JsKit on different sites.

I find Echo more complicated and more difficult to style. A bunch of what seems to be older legacy code is running around, their help and tutorials are complex and sometimes difficult to follow. They also seems to have slightly slower page loads, and deliver more javascript and objects. However, with the complexity comes more power and more options. They do require some payment, but this also gives you better sign-on options, ability to remove their branding etc.

Disqus feels cleaner and the because there are fewer choices it is simpler to use. Overall it feels lighter weight (in a mostly good way). However, the reduction in options means that if it doesn't do exactly what you want out of the gate, it may not be possible to do what you want at all. Single sign-on and white label requires you to contact them -- pricing is not public on their site.

I have had difficulties with both with regard to Facebook login (post OAuth 2.0) but I expect both to resolve these shortly. Tech support has been responsive for both (both unpaid Disqus and paid Echo).

Integration for both into wordpress was mostly ok, though there were a few bugs with migrating comments inside of Echo it wasn't anything too difficult to address.

In short, I would say I would use Disqus where you prefer a free, simpler, easier to manage solution, where you do not need to white label (remove disqus branding), don't require or don't mind multiple logins (logging in to your site and also to disqus).

Use Echo if you want more options, greater ability to customize, the ability to white label and to do single sign on.

In both cases you will need to do extra work to get SEO credit for blog comments and deal with occasional network slowdowns. You also have to live with their time lines for rolling out updates and features. If commenting is core to your site you may well want to bring it in house, otherwise either of these products work well.
You just painstakingly carried out the absolute analysis, which I know works.

Let X be the value in the envelope you have, and Y in the other one (X and Y are both random variables with well-known distributions). Then E[Y/X] = 1.25. That's what I wanted you to explain. You just keep saying that E[X] = E[Y], which I know.

Note that this paradox would not arise if X and Y were independent, since then E[Y/X] = E[Y] / E[X] = 1.
You wouldn't care to point out any particular section. It is quite a long document and the language appears to be a bit vague and political in nature. Or is your point that this is kind of document is actually part of the problem.

Either way I think that the NEIS program is a bit smaller that what these guys are talking about. If you do a NEIS program you are just as likely to be applying alongside people who are wanting to sell homemade candles at markets. It is really an employment program rather than ITC.
3G iPad to the rescue!

I actually have been using the iPad in coffee shops to catch up on email or read a technical PDF and have found that it's a much better feel than taking up a whole table with a big keyboard and looking for an outlet.

Of course for programming and the like I still need to be home with a real machine.
First, there are an awful lot of schools that offer semi-worthless MBA degrees as a profitable business. Much more so than in engineering or CS.

Then, it's because business expertise and talent is hard to verify. Programming or engineering ability is easy to prove, even at entry level. You can't prove you can manage a large group until you're already in charge of a large group. This means a company is taking a big risk on hiring MBAs versus CS grads, and needs to look for some clear, objective signals before going ahead.

Finally, executives like hiring managers who went to the same school they did. I don't know exactly why this is the case -- reciprocity, maybe, or some notion of a shared vision of how to run a business.
Just buy two extra battery packs or a portable power supply that you can fit in your backpack.
I've been using js-kit, or Echo as it's called now, since they first came out a few years ago. They've had some problems before (slow loading, delayed moderation), but they've been good lately.

I like that you can style the comments almost any way you want them with custom css. I like the analytics they give me, and the fact that they're pretty versatile with what they offer (custom html, video/picture embedding). Of course there's also the social aggregation feature which is pretty cool if you find it useful.

The pricing is a bit steep though.

Wow....just checked this out, created a simple "dapp"....it was pretty awesome.....I had never heard of Dapper before.

Thanks for the link :)
Woooo! My comment got killed! Because this sarcastic, snarky comment is surely better than one that remarks that even the parent comment was too stupid and inane to be popular on reddit. Thanks for the downvotes; really quite warranted here.

Yipee! Now this one's been buried! If I'm lucky, I'll get my account killed for having a couple of comments that are in the minority opinion.

Fortunately I know which direction reddit is! Ha
> "The bottom line is the modern diet contains a lot of refined sugar including fructose and it's a hidden danger implicated in a lot of modern diseases, such as obesity, diabetes and fatty liver," said Heaney...

Eggs were "implicated" at one time too. We're now seeing a shift from "fat is bad" to "some fats are horrible and other fats seem to be okay". Carbs have been all over the map.

Yes, today's information is likely to be better than yesterday's, but why is it likely to be the last word? And, are you sure that there's no face-saving going on? (There is wrt fats.)

BTW - Until the imortality becomes a possibility, tobacco smoking is a good idea if you're old enough....
I understood the blogger just fine, but I read Heaney's statement differently. I don't find it clear that he's saying that fructose use should be reduced strictly because of his paper and for no other reason, as the article implies (if it did I would agree with the blogger), especially when he said other bad things about fructose.

This is what we really know - in some undetermined context, in conversation, Heaney said

"I think this paper has a lot of public health implications. Hopefully, at the federal level there will be some effort to step back on the amount of high fructose corn syrup in our diets,"

To me it doesn't seem perfectly clear that Heaney intended that the first sentence, by itself, implies the second sentence, though the article sort of makes it look like he did. It's certainly not clear enough to rip him a new asshole, as the blogosphere has done, at least not based solely on the information in this article.

Cool idea. Why on earth it's presented as an image, and a huge one, I'm not sure I'll ever understand.

I'd tend to agree...

Taking a methods from a different domain in no way shows that the mechanics of those method don't reduce to the same mechanics as a "natural proof". Further, it makes the actual process much more obscure.

Indeed, statistics in general seems like a hard approach for overcoming the Razborov-Rudich limit, since the limit is on showing that a "typical" function has certain properties and anything statical seems like it would be "typical".

But who knows really, maybe Razborov-Rudich isn't correct, since in fully generality it relies on things that "mathematicians generally believe" (the existence of certain pseudo-random functions) rather than things that are definitely proven - as far as I know.
Unless I'm mistaken, you've completely missed the point of what I wrote. The reason wear leveling is not an issue is because the firmware is smart enough to avoid the problem, and those smarts interfere with the presumed model used by simplistic artificial benchmarks.
You don't.

You should find the one the best suits what you want to do, but also encourage others so as to avoid a monoculture.

Having multiple communities exploring different ideas is a Good Thing.

Amen to that, I was going to point out the same thing. With the new drivers from AMD supporting OpenGL ES 2.0 on all their cards and Nvidia supporting Opengl 4.1(full OpenGL ES compatibility) for their newest cards (fermi) WebGL is going to kick ass. I'm already using it in Firefox 4 beta 2 and chrome nightlies for work (building some scientific visualization software with it).
The one thing that really sucks about all Android phones is how they scroll. It's _really_ distracting and makes reading long content pretty unsatisfying.

Here's how it works: when you put your finger down on the screen it could be either a tap or the start of a scroll. The phone doesn't know at that instant which. It has to wait to make the call until there's been some amount of motion, about 1 or 2 cm, and until that time, the screen can't move (you don't want the screen bouncing around when you tap on things). So, when you start a scroll, when the phone actually knows it's a scroll, your finger has moved a couple cm but the screen hasn't. Android, for some damn reason, takes that instant to "catch up" to your finger, so that every time you scroll, the screen jerks up a line or two. No animation or anything. One frame it's down there, and the next it's up here. Try keeping your place when that happens, it's really annoying.

There is another way to do it too. The iPhone just doesn't bother to catch up. It works great and seems like no more difficult to implement.
Clojure like language for flash.
I don't know if "paid off" is the right word. If P were equal to NP, HP would probably benefit from finding out first. Assuming this is correct, though, all they get is the satisfaction of having hired the guy who happened to discover the proof in his spare time.
Here's an easy way to release some muscular stiffness if you're having lower back pain while sitting.

Stand up and feel your lower back and whether you can massage it easily.

With your arms back at your sides, bend both legs just 1/4 of the way down. Do this 3 to 5 times.

Now stretch the front of each thigh by holding the foot to your butt. Don't use a lot of effort to do this. Just hold in place for 5 seconds or until it completely stretches.

Now feel your lower back again and see if you can massage it. If its much easier to massage now, the source of your pain is your tight thighs. But now you have a way to cope with and reduce the consequences of this tightness.
What was obvious from how you asked your question was that you have some sort of grudge and wanted to bash on people you didn't like (e.g., "iPhone fanboys").

At any rate, other users aren't answerable to you for their votes.
A subject near and dear to my heart. I'm in Seattle, the coffee capital of the country. I've created a very comprehensive photo collection of paper cups from indie coffee shops ( http://www.flickr.com/photos/martincron/sets/721576066520024 ) and recently, I've found that I just can't bring myself to work from coffee shops anymore.

I tried for a few months to spend one day every week working away from my office, just to shake things up and to get some uninterrupted programming time. I just don't like the feeling of being some kind of freeloader.

I never felt right working through the entire day at one shop, so I would hit up one shop in the morning, have lunch, and then go to another. After a while, ordering beverages felt like a chore. Another americano? Bleh. Mint tea? Meh, I guess so.

The other part is that there's value to the whole "third place" concept; where home is place #1, work is place #2, and community is place #3. If you work from a coffee shop, it makes it harder to actually relax and enjoy the coffee shop later. Also, it's harder to actually relax and enjoy the coffee shop when it's filled with people on their laptops all day. There are a handful of places I don't bother going to because it's so difficult to find a place to sit (Greelake Zoka, for example).

What I really want to do is find a good co-working space to be my "second place". I signed up at one last month, but they kind of fell apart. Any Seattle area HN folks have experience with local co-working spaces?
The economics of libraries are different than you seem to think. Most are publicly funded institutions, and the funding is typically based on day-to-day usage (circulation, the number of people visiting, internet sessions, etc.). Late fees are little more than an incentive to actually return things, and are inconsequential as actual income.

Also, the exact needs depend on the neighborhood, but libraries help with a lot of social issues. I spent a fair bit of time helping kids who spoke little English with their homework, digging up resources for dealing with bad landlords and other legal complications, assisting with resumes and unemployment paperwork, etc.

If it was just another Barnes and Noble, it'd be different, but libraries are supposed to be a public resource for finding information. Research librarians were the original search engines, you know. :)

(Academic, medical, etc. libraries serve different roles, of course. I'm just talking about public libraries.)

In regards to mathematics, creativity is displayed foremost in finding connections between different notions and finding logical arguments to support a claim. Mathematical discovery is not in the claim, but in the construction of the proof of the claim.

Mathematical statements are generally easy to state. If P=NP were true, then a valid proof could automatically and efficiently discovered. This would be a kind of creativity automated by technology.
So much for relaxing.

"I think this paper has a lot of public health implications."

Extrapolating from tissue culture to public health is something that can be rigorously done. This paper doesn't address public health; as such, I don't see how it follows in a scientific fashion that this paper has public health implications. I don't have a problem with the work, or with the author, or with his beliefs about his paper. I simply disagree that his statement, quoted above, is justified by his paper.

The Rise of Homo Universalis
About two million years ago, homo habilis built basic tools to hunt and survive. About a million years ago, homo erectus walked fully upright and discovered fire to cook meals. Two hundred thousand years ago, homo sapiens inherited knowledge of only tools and fire. From those humble origins, we eventually managed to master agriculture, establish civilization, and spark science. Over the last few centuries, homo universalis has been naturally emerging by deducing the laws of Nature with methods of science and exploring the Cosmos with applied science. While still in early days of development, homo universalis will eventually lead humanity to the stars and beyond. Homo universalis is deep within all of us waiting to surface. If you stop and think for a few seconds, it would not be difficult to see the logical progression of apes from fiery creators to starry dreamers. LivGiv exists to aid a global shift towards universal consciousness through a paradigm shift in human technology. We believe it is the only way humanity has a chance of long term survival and prosperity. Don’t get left behind!

At the same time, the saying 'the more you know, the less you need' applies to the poor as well as the rich. those who can afford, for instance, a network connection, can easily find out how to build such things as mustard gas, thermite bombs, etc. The capability of one person to do damage has increased a great deal since the industrial revolution, and a great deal more since the explosion of such things as libraries and later the internet.

Up to a polynomial.

What if the polynomial is of order 1000 or higher?

I understand asymptotics and the convention that polynomial algorithms are "efficient". However, it might turn out that P=NP but the polynomial is so big that the found algorithm is impractical for normal sized instances.

Pick up their respective SDKs, read their docs, and spruce up on their primary languages (Objective C for iOS, Java for Android). Having a device for each will be needed in the long run, but you can get started with just the SDKs and emulators.

If I choose a platform now (iOS or Android), am I essentially "stuck" in the platform or can I jump between the two?

Not really, but as mentioned above, you will be jumping languages in most cases. If you're planning on supporting both platforms (or more), standardizing your back-end and any intermediary code/technology will save time and effort.

What do I need in terms of knowledge, skills, funds(?), to begin this learning process?

Funds will be specific to your venture, but a good foundation in C++/Java is more than enough to get you started. Get reading!

I haven't read the paper, but the blog post says it cited prospective human studies showing an association between pancreatic cancer and fructose consumption, so it looks like he digressed into something beyond cell cultures to make the case against fructose.

He could very well have been overselling his paper (the article certainly is), but it's just possible that the journalist made it look that way to get a sexier story. If the blogger had kept a more objective, factual tone, instead of attacking Heaney, I wouldn't have a problem.

Or, the future is the most competitive, up to date persons moving into a range of capability which allows them to marginally outcompete their less up to date peers, catching a faster acceleration. Their less up to date peers follow suit, but while they're retraining for their new devices, the leading edge is learning, faster than before, an even newer device.

Or, even better, the minds of kurzwiel's singularity are owned, trained, and taught by competitive corporations, who's only job is to make a great deal of money. The best firms are the ones who compete in the harshest manner, and again, the average gets left far behind. I think its far a mistake to assume that more stuff means an egalitarian future.

sorry, didn't mean to say you implied. just reiterating something.

Sitting all day is just an aggravating cause, not the underlying cause. A muscle gets stiff under a light load only when circulation is impaired. A muscle with good circulation will not get stiff.

So it isn't that we sit for long periods. Its that we haven't fully exercised our full range of motion on a regular basis. We haven't kept the normal deposition of collagen from essentially gluing our muscle sheaths into something stiff enough to impair blood flow to the muscles inside them.

That's my theory anyway. And part of my understanding is that this situation is totally reversible.
