When you have to belittle your child to motivate them, it truly speaks of you as a parent.

IIRC from what I read on Carrot VS Stick methods for dog training, a combined usage worked effectively ~95% of the time. The carrot worked effectively ~80% of the time. The stick worked effectively ~30% of the time. No reinforcement worked effectively ~14% of the time. (I'll have to dig through my books to find where I read these figures)

Why do I have the strong suspicion that this woman's kids are a huge ass exception to the psycho-parenting norm?
Switching costs are absolutely the thing to focus on here, but limiting the switching costs to a replication of the social graph may be understating the true cost. Think of all the photos, and to a lesser extent, wall posts. I would imagine a lot of the time that's spent on Facebook is just browsing through photos (and again, to a lesser extent, people's wall posts). Much of it probably is just new photos, so obviously those don't need to be replicated since if you port the social graph over, people will start posting photos on the new site and people will just look at those, but a ton of the viewing is probably of legacy photos. That is, some of the viewing is seeing what's happening with your friends (the party last night) but a ton of it is just checking people out (facebook stalking). How can I stalk somebody without seeing all their past photos/videos/notes/posts/etc.?
I would love it if it the browser could run it natively. But if we're replacing browser language, can I just have plain Ruby?

No, this is terrible for noobs, believe me. I've tried with friends trying to learn programing and it was incomprehensible to them.

Ask HN: CMS for a programming language reference
Hi, I'm working on a programming language project and am looking for a good hosted CMS solution that I can use to document the language reference. So far I've tried github's wiki system (since it is then tied to the project), but I find it woefully lacking.

I'm close to resorting using Pages and generating a PDF, but before I do, would like to give a few other CMS's a try.

Can anyone suggest a hosted CMS solution?
These days I find this comment by coffeemug (lists three things) relevant when it comes to advice regarding programming as a career : http://news.ycombinator.com/item?id=1747713
In my school district, we have been using Blackboard Learn for as long as I can remember. According to Wikpedia, it's the "next generation learning management system". In essence, it provides a way for teachers to interact with students, as well as for students to interact among themselves. Posting grades, class announcements, and homework assignments are only a few of the things teachers can do through the site. Students can view all of this information, as well as form groups, run blogs, use calendars, and create discussion boards.

My point is that Blackboard is not a piece of ugly software. It is fully functional and has a nice and intuitive design to it. The article says that:

Badly designed software with poor usability goes hand in hand with general appeal

However, this software is not badly designed as it does what it is supposed to do (and more), and the usability is perfectly fine. Ironically, our district has switched to another piece of software to replace Blackboard's, but only because of the teacher's belief that it offered too many features.

I think that the author of this post should rethink Blackboard.
DARPA contracted with universities to create it. Just because the military's interests were once aligned with advancing communication technology between academics doesn't mean we should accept that all or even some of the current government's "involvement" is simply for the betterment of mankind. These people ultimately rely on the threat and use of force to do their "job" no matter how remotely connected its authority is to the U.S. Constitution.
Also we have to keep in mind sometimes incompetent IT people are in charge. We had a grad who came back and designed a software for the entire school (potentially district) to use.

Although it's in place, it's been severely restricted due to irrational concerns over security and other illogical arguments. In order for the buying to even occur (keep in mind this was free for the school), there must be knowledgeable IT people in charge.

This is a much smaller scale here since it was for a high school instead of a college, but you'd be surprised at how incompetent people can be.

Right now in the IT people I work under at the university are smart, but lightyears behind when it comes to good user interfaces and the latest technologies.
For poor visual basic coders, it's easier to use standard dialogs than make custom ones. In the old days the Yes/No/Cancel text would be hardcoded into a specific dialog object.
More appalling than hilarious. Putting even the algebra aside, by this logic the following would be forbid in this school:

-Thomas Edison assisting in a science lesson
-Bill Gates helping kids learn to program
-John Rockefeller teaching a business seminar
-Michael Dell talking about supply chain
-Walt Disney teaching an art lesson

All never obtained a college degree (save honorary ones). It would be one thing if primary education had a basis for its elitism. But instead they're failing at an increasing rate.
It's not the choice of keyword that (should) trigger the warning. It's the simple fact that an expression that evaluates to boolean contains an '='. This potential error is trivial for any compiler to flag.
That would be a broken compiler.

Facebook needs to generate more revenue or if they go public, their stocks are going to tank like crazy after the speculation fades. Facebook's P/E ratio is out of proportion. Doesn't matter how many users Facebook have, if the company doesn't generate the proportional profits to match its valuation, then the company is going to go through some tough phases.

Many people are looking at the Facebook stocks like it's a Pablo Picasso painting, and with users twice as the population of United States, it's bound to be valuable. However, in the economy of supply and demand, the bubble will pop if it decides to go public. Unless Facebook can think new ways to earn more money.

But that's hard, because Facebook users hate changes. They aren't exactly Obama fans.

"The involuntary and almost imperceptibly slight movements of the hand holding the laser device of the present invention creates a jittery animated effect in the light pattern at the opaque intersection appealing to cats even when the device is held essentially steady."

I hope the production model infantry laser rifle of the future is forced to include patent 5,443,036 on account that even in the hands of a bio-mechanical super-soldier, the jittering effect of the laser's appeal to cats was patented decades earlier.

Another piece of evidence that software patents are harmful.
Does anybody have good data on conversion rates for credit card info at the beginning of the free trial or end of the free trial? That is, let's say you e-mail the user 5 days before the 30 day trial is over in both scenarios, but if they entered the credit card info beforehand, then to sign up the user has to do nothing, but if you require it at the end of the trial, they now have to enter credit card information to continue. So basically you have to add the credit card burden at some point; do you get a higher conversion if you increase the barrier for the trial (by asking for cc info up front) or the barrier for continuing (by asking for it at the end)? I'd guess that asking up front has the higher conversion, but I'd want to see the data.
Vim offers strong file encryption with Blowfish
My experiences with Blackboard paint a far less flattering picture. An "intuitive" interface is entirely subjective, but I've hardly ever tried to do something new without wandering through confusing, cryptic and downright hidden menus for half an hour. Computed columns in the gradebook are crippled for no reason (formulas cannot be nested) and use an obscene[1] "keyboardless" entry form with pointless user-side validation. If you ever want to give yourself a migraine, crack open the source to any nontrivial page and try to tease apart the miles of needlessly complicated and frequently broken Javascript.

Granted, my university does not use the latest-and-greatest version (yet) of Blackboard Learn, but for someone with your history of using the application these should not be totally alien points.

There's a grain of truth to what you say, but it's misleading to attach it specifically to Google.

Whenever you're doing something for somebody else, they're going to want to see two things from you: 1.) that you understand their problems and concerns and 2.) that you're doing your due diligence to address them. It doesn't matter whether it's Google, some other big corporation, your own startup, or a consultancy. If it's your startup, your customers will want to make sure that you understand their problems and do your due diligence before they fork over their money. If it's your consultancy, your clients will want the same.

I've found that teams that understand this, grok Marissa's way of thinking about the world, and are willing to put in the legwork to iterate on their ideas and make them as good as possible have quite a bit of latitude to do what they want. Those that just spit some <div>s onto the page and come unprepared tend to be the ones that gripe about how Marissa blocks them from getting anything done. Many of the teams I've seen that had problems with Marissa also had terrible UIs, and I'd really hate to inflict them on the user.

In many ways, this is just another way of saying the same thing you did - if you want to be successful, you need one of the decision-makers to back your play. But that's the case anywhere. I've been fond of saying that entrepreneurship is just trading one boss for many bosses - it's great if you hate your boss, not so great if you hate your bosses. Which is a good reason to pick a company or market whose bosses you fundamentally agree with.

Also, speaking as someone who let his startup die because pretty much everyone with social influence over me expressed doubt - if you give up because of what other people think, it'll severely limit your ability to get anything done. If senior executives don't like your project, the best thing to do is listen to them, figure out if they have a point, and if they don't, go do it anyway. The worst thing that happens is that they fire you, and then you're in exactly the same boat as if you quit to found a startup, except that you've been learning about the problem domain while drawing a paycheck the whole time.
Terrible loss.

Based on his note, he is a compelling writer. If it were not published posthumously, it could have done a lot of good for himself and for others. It probably would not have received the same amount of attention though.
Selection bias. The author is published because she ended up a professor at the top law school in the country. Plenty of Chinese mothers raise mediocre children, and they don't get to write opinion pieces in Murdoch rags. (Or did you take it literally when she claimed that Chinese children don't get B's?)

But you're right that this parenting style has benefits. It strikes a chord with me, as a parent of small children, when she says that you're not doing them any favors by letting them give up. But parents have to find the right balance. Maybe the author's children benefited from having both kinds of parents, one strict and Chinese, one doting and Western---Cue shock and horror from Chinese grandparents. I know many successful children of mixed East/West families. Sure, that's anecdotal evidence, but so is this article.
I would suggest using Python + Tornado (http://www.tornadoweb.org) for an easy-to-learn and lightweight web framework however it is very sparse in terms of documentation and there are not many guides out there covering Tornado yet. If you are up for the challenge then I say go for it; if not then I would suggest learning Ruby + Rails in order to get exposure to basic principles on web application design.

If you decide to go the ruby on rails route then I HIGHLY suggest getting Agile Web Development with Rails (http://pragprog.com/titles/rails4/agile-web-development-with...) as this proved invaluable to me when I first started out. Best of luck!

Please, to anyone so passionately critical of W3Schools:

Write highly-accessible tutorials that teach the way code _should_ be written.

Until that happens, noobs will continue to rely on W3Schools (and perhaps Tizag.com) for learning the all-important first steps for programming.

I have almost zero formal education with programming. Thanks to W3Schools and Tizag, I was able to get started and eventually become a technical co-founder of a startup.

Looking back, here are some of the most important things I learned from these two sites:

-HTML renders into a readable web page

-Server-side code ultimately renders into HTML

-The source for server-side code is private

-The source for client-side code is public

-You need a database to store data (not so obvious!)

-You can organize code in certain ways to make your life easier (eg. writing functions)

-The very basics of OO concepts

Without W3Schools or Tizag, I _never_ would have learned these concepts. No one was going to sit down and teach me, nor was I going to magically deduce them.

Bottom line: W3School lowers the barriers to entry for learning how to program. This can only be good for the startup ecosystem, and ultimately, for the economy.
It's as serious as a heart attack. Everyday billions of dollars, which represent immense man power and dedication, are spent in pursuit of the unearned. That means the goods and services you buy today are more expensive because every dollar you spend is competing with all that borrowed money. That alone is plenty bad.

I won't even begin to talk about the repercussions of bankruptcy (or runaway inflation) that you shrug off. Modern day Greece, pre-WWII Germany, Zimbabawe aren't/weren't tourist destinations for a reason.

North Scottsdale was spotty when I lived their two years ago. Anything near the McDowell's is likely to drop calls or have no reception at all on AT&T, while Verizon was fine. I actually had no problem with AT&T (Cingular at the time), many years before, but it seems as data phones became more popular, AT&T's network quality dropped.

I've since moved to Seattle, and AT&T is atrocious. There is hardly a day where calls don't drop and I find myself on Edge in the middle of the city far too often.
