None of these features are necessary to build a production-ready Rails site. Before Rails 3, people built and deployed production-ready Rails sites. Production asset optimization was left up to the developers to figure out. Rails 3 makes asset optimization very easy by comparison to what needed to be done before.

Rails has not become more complicated to develop for. Rails 3 just has more features than it used to have. If you want to use more features, the features are there for you. If not, you can ignore them.
JqBootstapValidation - A jQueryValidation Plugin For Bootstrap Forms
jqBootstapValidation is a jQuery validation plugin for Twitter Bootstrap forms. jqBootstapValidation supports the following validators:

HTML5 BASED

Email
Number
Required
Max
Min
Max length
Min length
Pattern

EXTRA VALIDATORS

Match
Max checked
Min checked
Regex

BUILD YOUR OWN

Mix and multiply

Internally, jqBootstrapValidation only uses data attributes. By default, it will also sniff for native HTML5 form validation attributes, as detailed above. If you decide this isn't what you want, you can restrict jqBootstrapValidation to only data attributes by setting sniffHtml to false when calling it on your form elements.

By default, jqBootstrapValidtion will prevent forms from submitting if any of their elements fail validation by jqBootstrapValidation. If you decide this isn't what you want, you can allow submitting of potentially invalid data for validation server-side (or in case you think someone might have a genuine case for exceptional data).

Cost per kilo to Low Earth Orbit (LEO):

Space Shuttle: $19, 824 per kg [1]

Soyuz-2: $5,333 per kg [2]

Falcon 9: $5,167 per kg [3]

At the moment, the Falcon 9 is not that much cheaper than the Soyuz.

Elon Musk's talk of $1,100 per kg lies in the future. SpaceX is hoping that making all the parts reusable and its new Falcon Heavy (Which will carry five times as much as the Falcon 9) will cause launch costs to plummet like a stone.

Which is not to say SpaceX isn't amazing. It has been launching rockets for that past 6 years. Whereas Soyuz has been the 40 year work of a superpower. Achieving parity is a wonder in and of itself.

Why Is Bootstrapping Important?
Well yeah, I just pulled that number out of nowhere ;-) Thinking about it more seriously, it'd be closer to one!
You're not frustrated that it's near to impossible to buy a Windows PC without a bunch of crap on it? I've set up plenty of PCs in my time, and I absolutely loathe the process. I can't simply turn the PC on and turn it over to whoever is going to use it. They'll encounter a continuous barrage of trial expirations and prompts.

What do we expect Microsoft to do about it? Nothing, really. It'd be nice if OEMs took the high road, but they're not going to do that either. Does that mean we should all just shut up about it? Heh, that ain't happening' either.
Comments like these make me wish I had the ability to downvote.

This sums it up. Similar assumptions about the human mind are what have led to the current poor state of the US education system. Teaching and learning are not one size fits all.
Dr. Johnson defines bigot as:

... a man devoted unreafonably to a certain party; prejudiced in favour of certain opinions; a blind zealot. It is ufed often with to before the object of zeal; as, a bigot to the Cartefian tenets...

I'm pretty sure you're not a bigot to the Cartesian tenets. You do strike me as pretty zealous, though - n'est ce pas?

I am actually quite okay with bigots and bigotry. We can't all embrace change. We don't all have to. One thing is certain, though - if it's not surprising, it's not change. Welcome to the 21st century!

"Programming is hard, especially for minds that are not well accustomed to breaking things into linear series of events."

Or maybe many people are just lazy? As for the linear events, can you cook? Can you give directions to the main station? I think most people serialize things all the time. Like, do you ever create a ToDo list for your day?

I can't imagine that it takes months to learn how to load some images into Excel. Unless you have to learn how to read first. And Excel could be one of the hardest things to program...

"But please do recognize that programming is not intuitive for everyone!"

That's just the thing. Programming is hard even for programmers (hard not as in impossible, but hard as in "lifting 100 pounds of the ground" or whatever - it is work). But they are diligent enough to solve the problems.

It really irks me when (for example) business types say they are not made for programming. In fact I don't really enjoy programming either. I enjoy making things, and programming is just the necessary evil I have to put up with.

This logic of "xyz is not intuitive for me" is just an excuse to never even try to cope with maths or whatever.
Records labels hardly pay for studio times these days. And forget that if you are a new unsigned band. And that is what they are targeting, right?
> The memory hierarchy can never completely flatten. Information takes physical space to store and the speed of light is finite. So the more information, the further things are apart, and the longer access times will take.

Not necessarily. Memristors were shown to be capable of performing logical operations [1]. Given that, one can imagine computations migrating through the circuit to stay physically as close as possible to the data thereby eliminating the need for caches.

you'll be surprised what chinese have achieved. there is currently on sale chinese tablets with dual core cpu and quad core gpu, 1gb ram, 16gb storage, 10inch IPS screens and all bells and whistles (like HDMI output, SD card support, dual USB ports etc) with 7+ hours of battery life for 215 USD..

its all a matter of a win8 RT driver for the particular SoC.

run a search for "Rockchip RK3066" SoC (in particular check for a tablet called R2000 or Cube U30GT.

I already own the single core version of that tablet and i assure u the build quality, screen etc are in par with ipad2.

I always liked "Godels Theorem Simplified". It doesn't rely on heavy technical prerequisites in mathematics or CS. It is pretty much as advertised, a simplification of Godel's original proof. Godel used a more complicated encoding scheme using prime numbers, which Gensler replaces with a simpler encoding scheme. He walks you through various less powerful formal systems, before you get to one complicated enough to have incompleteness issues. There is also discussion about the philosophical ramifications of Godel's theroems.

"Godel, Escher, Bach" is another interesting read, but that volume does have a lot of extraneous fluff.
Facebook Employees IPO Quotes
How Facebook Employees celebrate IPO?
To be honest if I could go back and talk to myself ~2000 and I said that the most exciting , hottest Internet company in 2012 is a website that allows users to post text based messages to other users of the same website I would have been somewhat disappointed.
Nope.

It does, however, posit that the offset value of the difference in frustration between the experience of buying a new PC is sufficient to drive consumers to Apple though.
Bravo, a poignant demonstration of the value of collectivism through code.

This post prompted me to go check the people we accepted onto the UX stage of Agile 2012 - and we have a 50/50 male/female split. Merit based - sex wasn't a factor in picking speakers. Makes me rather proud of the community we've built up in that particular field over the years.

And community building is what changes things in my experience. People attend conferences to have fun and learn. Speaker or audience. Lose some of that in however small a way for some group and you start losing traction with that group.

I know people who don't attend particular events, or in a few cases conferences in general, because various attendees or organisers or sponsors acted like asshats. Word spreads and it affects future years attendance and submissions if the organisers aren't proactive about dealing with the situation.

Even worse it casts a general air of malaise over the whole field. Attend two different conferences in a row where you're made to feel uncomfortable in one way or another, and it makes you a little less likely to attend the third.... an so things spiral...

The door maybe open - but people's views are tainted by discovering what was actually behind some other supposedly open doors.

Doesn't it bother you that you won't be the one doing the exploring? I'm insanely envious of these people and sometimes I wish manned spaceflight would end. Standing on the Moon sounds like the most amazing experience I can imagine and it pains me that I won't ever get there and even if I would, I would just be the umpteenth tourist, littering up the place.
Why do you assume that the community is unwelcoming toward women? Isn't it just equally plausible that women just don't really want to be in technology-oriented fields? Maybe they just much rather prefer other areas. I know, the thought that men and women are actually different is deeply troubling to those who think that the only differentiator beween the sexes are a couple of sex organs.
Very true. Have you read his biography? One of the things that also struck me the most in there is how often Steve seemed depressed even with all the "success". He seemed to be crying in so many stories. Even after every revolutionary thing he had accomplished, the launch of the iPad 1 made him depressed, because it just couldn't match his expectations.

Another reminder that no matter how much you achieve or obtain, all of us have a sense of ambition that can easily ruin our happiness if we don't keep it in proper control.

Thank you for your comments and suggestion. I'm aware that Apple doesn't like this too, and am only asking for help because of 6 rejections in 2.5 months. It's hard when all you get is a cryptic message that hasn't changed in 3 rejections regardless of what you do. And because some crap app that is a horrendous copy of ours is sitting pretty at number 2.

It does make sense that it is possible that Apple's configuration is having problems. I'll try to test it with more devices over the weekend. Thanks!

The value of a billion people being connected is priceless. This ability isn't exclusive nor controlled nor owned by Facebook though, so allotting a value to Facebook based on this is bad idea. People are mobile online. The internet itself is the platform allowing this, not Facebook. They showed that there was a need to be filled, though aside from that, overall they aren't doing what's best for users/consumers/people.
It could. When there is a lot of talk about startups in the press, that increases the supply of programmers, because it makes more people study CS. But as I pointed out in another comment, big companies could be responsible for more of the increased demand for hackers than startups. If so, "overvalued" startups could be net helping rather than hurting the job market.

I'm not saying this is the case. I don't know. If were going to write about this topic, I'd start by looking at the world and seeing what's actually happening.

We've tried this too. But beyond the standard "We'll contact you shortly", nothing has happened after weeks (3-4 weeks).
The problem is that there seems to be only one definition for success (lots of money and being talked about in the news) and we tend to compare ourselves and others against that measure of success.
Running a lifestyle business and creating a handful of jobs, taking care of your family and friends, helping the needed, being an excellent teacher, having an healthy lifestyle, (insert here what makes you get up in the morning) are also huge successes, they just don't make the news.

I remember hearing the same thing about TiVo. They had so much interesting information on what people were interested in that pundits predicted that they'd soon be giving away the boxes for free.

For all of Facebook's data collection, they don't seem to be able to do anything with it. To put it in perspective, I just logged onto facebook and got an ad from a company hiring coal miners. I'm asthmatic, despise big coal, currently employed, have cerebral palsy, and live three states away from this company. I could have targeted that ad better by randomly pulling a name from the phone book.

Other ads include:

* Beer - I don't drink

* Tickets to the Avengers - Okay, I do want to see that movie.

* Getting my Bachelor's Degree Online - I already have a master's degree. Facebook knows this

* Bait - While they get partial credit, since I enjoy camping, I'm not into hunting or fishing.

* Tequila - See above

* Lawn Fertilizer - I live in an apartment

* Airfare from Chicago to Oklahoma City - I don't live in Illinois or Oklahoma. Facebook knows this.

* Hunting Rifles - See above

* Vodka - See above

Conversely, Facebook should know that I'm attending a conference in DC next month, but there hasn't been any comments on restaurants or attractions in that area.

I don't deny that they have a lot of data. However, I think they're in the TiVo situation where the data simply isn't that interesting.
The cheap ones there are all 7".

While Zuckerberg has a complete majority, in what ways do they have to answer to shareholders? Fear of stock price drops as people sell off? Reporting requirements?
I think you've made some good observations around the expense of material goods, but as the parent of two kids, I already do this. It helps, but it doesn't address the really expensive things about life with kids.

For me, the big whoppers have been day care and the loss of income on scaling back on work. Full time day care is about 24K a year in San Francisco.

http://www.housing.berkeley.edu/child/facstaff/

This is the faculty/staff daycare that has a long, long waiting list at UC Berkeley - it is considered a very desirable program, so it's possible that you could get something much cheaper.

Another huge expense is housing. I fit a family of 4 in a fairly small (1200 sql ft) house with a garage and backyard (sweet!) in an unfashionable part of SF. Mortgage runs me about $3400 a month - sadly, if I'd waited to buy, I could probably have had this for $2600. Rent would probably be somewhere around that range.

Buying a stroller used is a great idea (I bought all cribs and beds used, and it saved me some money, but I'm really optimizing around something that takes at most 10% of the budget, if that).

I want to be sure to say I'm not complaining, I consider myself pretty lucky to have these things. 1200 sq ft with a garage and a yard is pretty excellent. Nice day care is a luxury. And I get to live in SF, which is where I grew up, and I really like it here.

I wouldn't say you "can't have kids" if you can't afford these things, so I agree with you there, but I just don't think you've identified the real heavy hitters where it comes to the expense of raising a family.

But I really don't think the problem with middle class people is that they are spending too much on strollers. It does take some serious $$$ to stay middle class in San Francisco.

"I think the point is that if you try to add those unprovable theorems to the system to try to make it complete it becomes inconsistent."

Eh? No it doesn't! If you add Con(PA) to the axioms of Peano arithmetic you obtain a stronger system. That system can't prove its own consistency, of course, but if you have a proof that the system PA + Con(PA) is inconsistent then you're probably in line for a Fields Medal.

Alan Turing worked on precisely this issue, developing ordinal logics in his PhD thesis (with Alonzo Church) to try to overcome incompleteness. Soloman Feferman, who in the 1960s proved a stronger result than Turing obtained, has written about this extensively. An accessible paper is this one:

Pathetic extra, only I am real and you are all just extras.
Wow, sorry, that sentence I constructed there was really confusing. There are really two separate effects. On the one hand, you can only make a cell of this memory so small, so you can't pack it as densely as you'd like. The other is that you have one cell of memory you'd like to access, and an output line you'd like the data from it to go out on. And you don't want the data from any of the other N billion cells of memory to go out on that line. There are actually some structures you use to retrieve that particular bit, but the more bits you're selecting between the more delay is introduced. In most current CPU designs this is a actually a bigger deal than speed of light, at least for the various levels of on-chip cache.

This certainly does not apply to conferences that cost a cool four figures to attend and are geared towards the corporate market. Nobody can tell me that the organizers are not making money.
The vast majority of people use computers merely as entertainment devices and thus have no reason to learn programming. Or how else do you explain the success of the iPad? It's been out for years, and whenever I see one I still think that it's a patently useless device (at least for me).
I'm not sure I believe that number. I guess some super highly-paid regions are throwing off the average.

Starting teacher salary in my district is $42,000 per year for a 187-day contract. Assuming the teachers only work 7 hours a day (which is insultingly low; my first year teaching I worked 60-70 hours a week): 42000 / 7 * 187 = $32.09 per hour.

I think if you (wrongly, IMO) assume that all teachers in America work only the hours that they're on the clock in front of children, then MAYBE that number is believable. But that's not the reality of the teaching profession, in my experience.

Edit: I see that number is "total compensation", which presumably includes health care and such. I don't know how to meaningfully add that to my estimate, but it would certainly increase it.
Money is simply a metric of how people value you. It is a little disheartening to know that nobody cares about what you are doing when you've poured in so much effort.

It's not that anyone actually needs billions of dollars, but if you are not making millions/billions of dollars, you start to question what is wrong with you that causes people to not care, when they obviously do care about these other people.
You sound angry. Not sure why. Some feel that his tax evasion efforts are unseemly. Not sure why you're focused on his lucky strike.
