that is true. we were taught to do well in school. I know that this phrase has been repeatedly used to describe our youths, but it holds a lot of weight. How many of us would have dared to risk scoring below 200 for our PSLE to explore building up a nice webpage, or a nice storefront for our Neopets shop? All these experiences are actually the start of programmers.

I am guilty of being caught up with the grade chase, having gone through a good secondary school followed by JC, and now Uni. I find it too late for me to realise this only now. But i am not disheartened. We need more superstart stories like the acquisition of Brandtology and Beeconomics to let the youths realise..it is never too late to start.

thanks for your recommendation on the incubator system! in fact, Singapore is starting to pick up in since last year. There is now a Singapore chapter for Startuproots. Perhaps we are on to something in the next 5 years :)

thanks for the reply!!! really appreciate it
The Cypherpunk Revolutionary
trivial, but Opera's at 11
I love OCW too and I don't agree with the evolutionary/revolutionary statement. Revolutionary would be OCW or TIMMS as they started this free online video lecture thing (there could be an earlier initiative which I'm not aware of). I also dont really like the 5-15 minute thing but thats individual preference.

If we consider views proportional to impact, then a glance at the viewcount of some OCW or Richard Buckland's lectures on youtube show they're in the same popularity range as KA.

Also, I should've mentioned the Stanford youtube channel in my list. Its pretty good, covers several undergrad/grad courses and also available via iTunes.
Today, and potentially then as well, there is virtually no strategic value to the moon whatsoever. Surveillance of earth and space and communications can both be done more cost-effectively by satellites, exploring further into space is not especially easier with the help of a moon base since the moon is still well enough within Earth's gravity well not to make for a useful waypoint to outlying destinations, and the other justifications are completely question-begging.
Popville Pop-Up Book
The article talks about the genetics, but doesn't really answer the evolutionary question. So I'm going to speculate in a somewhat informed fashion.

First I'll start with a fun fact. Humans have a penis that is several times larger than you would expect looking at other primate species. In fact there is clear evidence that humans have undergone sexual selection for penises that women like. (And there is evidence that women enjoy size.) By contrast what a chimp's penis is like is pretty much the least important thing about him as far as the female is concerned. Much, much more important is how big and strong he is, and likely to pound her if she doesn't comply with his wishes RIGHT NOW. (Chimp sexual behavior is really not very nice.)

Therefore I'm going to propose a hypothesis. They have suggested that spines help in removing your competitor's sperm. I'm going to suggest that spines are less pleasant for females. Therefore in humans, who seem to have undergone sexual selection based on what women think about men's penises, spines have been lost. While in most other species, where female preference on penises is not a sexual selection criteria, spines win.
When I was a kid I was naive (and still am, to a degree) and I thought that in the future machines/computers/automation would do what humans didn't want to or simply couldn't, not to make a few people rich and bring more comfort to upper middle class, but so that humans worldwide could go after more important things that could make us evolve as a species.
Wouldn't that only be true if the cost of developing osx was 0? Isn't it possible that HP pays less per license than what it costs Apple to developer, support, ... osx? Isn't that one of the points of outsourcing?
Take the same approach as grubwith.us and groupon did, avoid the PayPal risk.

However, if you believe there's a significant advantage of having PayPal (doubt it), then you may want to consider setting up an eBay store and handle all payments for reservations through BINs on ebay pages... vayable.com would then become a "wrapper" around your ebay store. Additionally if you get significant traction, you may get $10-40 for every person who registers with ebay through your links.
This is still not really a good option. Have you looked at the contracts and requirements on payment processors? The options suck. Credit cards are a bad, bad system for merchants because the banks totally have everyone by the balls and in typical bank fashion they are not afraid to put the squeeze on.

I hope one day someone comes up with a real electronic payment method. Bitcoins are currently our best hope, but they're not a very good hope.

Why Should You Outsource PHP Development to India?
PHP is growth engine of web world, which is expanding at rapid pace to encompass the growing needs of the people. This server side scripting language is easy to learn and developer friendly. India with its vast pool of English speaking PHP developers becomes an attractive destination where you can out source your PHP application development needs.
Thanks jerf for your feedback even though it was based on rapidly reading the document. I will address a few things:

1) In general I am trying my best to not change the syntax for Erlang data structures. Atoms were one of the few exceptions due to the grammar. I chose to go with the lisp syntax (and similar to Ruby :symbol). But indeed I could have chosen it to be apos-delimited at all times to be closer to Erlang, I have to think more about it.

2) head and tail: good point. The reason they are there though, is if you need to dynamically dispatch a method to retrieve the head or the tail. But in general, I don't think we should limit the language to avoid people writing bad code. We can better solve this problem with good docs (therefore I have removed such bad examples from the README).

3) Empty lists being considered false: I was not sure at the beginning if they should evaluate to false or not but after your feedback I have decided to change so just false evaluates to false. Although in some cases it if feels very weird that a proper nil is missing, for instance Object.__parent__ returning an empty list that evaluates to true feels weird. Maybe I should add nil down the road.

4) "Merely tweaking Erlang" can you give examples where we may be merely tweaking Erlang?

5) case/match: I borrowed the syntax for Ruby and yes, Elixir is not whitespace sensitive. In Ruby, people indent case/match in both ways, I am particularly fine with both.

6) try/catch: yes, I also would like exceptions to be objects (like Python and Ruby). However, the fact I cannot easily have custom guards in Erlang makes that considerably more complicated to implement. Maybe we can add it in the future if more and more people start to use Elixir enough to justify putting a lot of effort in complicated features.

7) String interpolation: I am not aware of such issues. If you could point to more references or discuss it better, I would really appreciate it!

8) The inlist is because we need to make a difference between list and binaries when there is an ambiguity. So what exactly do you propose? To always be explicit here (using inlist or inbin)? Notice that this is an Erlang limitation, the Erlang syntax uses <- and <= to make a difference between them both.

9) Method visibility: hrm, you are actually right. I could have started without this feature and have added it if I eventually needed it. We need the private methods (because they map to local not-exported methods in Erlang) but protected methods could definitely be gone.

10) The GenServer example is not missing, it is in the examples/ folder (too long for the README):

https://github.com/josevalim/elixir/blob/master/examples/gen...

Elixir has also Code::Server (that stores your load paths) and ExUnit::Server (that stores your test cases) that could be used as examples. GenServer in Elixir is very OO'ish and I am particularly happy with the current implementation after going through a few iterations.

Writing Elixir has been an extremely rewarding experience and reading your feedback makes it even better. Thanks again for sharing and I hope you can eventually use it and help us improve it more!

Importance of PC Computer Recycling
There are quite a few benefits that can accrue from recycling computer monitors and pc recycling. It is not only an excellent way of contributing to environmental preservation but can also prove advantageous for organizations.
I think the biggest difference in making it revolutionary vs evolutionary is the target audience. OCW and their kin are all targeted at people that are highly motivated (and generally highly educated already) to learn something new.

While Khan academy is targeted at a mass audience. I think both serve their target audiences very well too. I'm nearly addicted to OCW, but it's heavy stuff, not something you can sit down with for 10 minutes at a time and make progress.

In regards to your comment on impact. Khan academy in its current form has only been around for months while OCW has been around for over 10 years. In my daily life I've only met one or two people that have even heard of it, while the Khan academy is already being mentioned by people I know independent of my experience with it.

Have you contacted your own bank to ask them what your options are?
By the time you hit residency, you are so far into debt that not having a job that pays $100k+ (eventually) is suicidal. That being said, some people do drop out.

I know one person who dropped out, but was at married to another resident, so has a safety net. Another resident dropped out due to a medical condition that prevented him from standing for hours a day and landed a job at McKinsey. Another friend dropped out and became a receptionist! Eventually she went into a residency for a lower stress specialty (surgery -> psychiatry).
I have long found the rave about smart covers a bit ridiculous considering what a very minor addition they are, but this description is just funny to me:

Apparently the last weeks code rule was a surprise, I don't think the vendors knew about it.

I'm not sure this sort of last-minute patching would make much difference

Even if the vulnerability is still there, screwing with the way the binary is built and linked could easily make it so they'd have to put it back in a debugger and retune the exploit.
The downvotes you've gotten aren't fair but it's worth pointing out:

It's this kind of thinking (on the part of their competition) that lets Apple keep their head start for way, way longer than necessary.

The short answer: Because what you're proposing would be terrible.

Apple's money magnet is creating a sense of delight and surprise. You'd be mimicking the result, a snap on cover, without grasping the intent, which is to make you feel like a kid seeing magic. People don't want a cover. They want to be delighted by a cover.

At least, they do now, since Apple has shown them it is possible to feel this way.
My take on the Machine Learning 101 class that just ended: http://btubbs.com/2011/02/26/machine-learning-101-course-eva...
In terms of web startups, what PayPal offers over most other services is simple: let the user directly enter a credit card number to pay you some money - without the user having a PayPal account. There are lots of options for payments such as Google, Amazon and others but they all require the payer to have an account. PayPal doesn't - you effectively get credit-card processing with no setup and no hassles for absolutely nothing (apart from transaction fees). Compared to getting a merchant account etc, it's child's play. Of course, the "hassles" part turns out to be not so great once they suspend your account.
As a university math TA, my students would often say "you're so much better than the teacher, why don't you teach the class?"

Hearing this is definitely an ego stroke, but what the student really means is that he learns better by practicing problems than by listening to theory. I feel this is even more true in a younger school environment.

The teacher's and TA's roles are simply different in this respect, so I take no credit for "being better than the teacher".

But what Khan Academy does is really interesting, because now the teacher takes the role of the TA. I feel this is a much more effective way to teach. And ultimately the student will benefit. Thumbs up to this philosophy.
From what I've read about polyphasic sleep, it doesn't seem to be best for humans. A lot of people have difficulty with it. I've come to the conclusion that people are biphasic. I think people perform their best with a long night's sleep and then a short nap around 2pm. I've noticed this works for me. YMMV.
The abandonment of technology - Are we working on the right problems?
The record keeping is a double edged sword. Maybe one day institutions will start using your Khan record as a metric for employment/admissions. And that's the day people will start cheating. I guess this means standardized tests like the SATs and GREs aren't going anywhere.
How I lost my faith in Lisp
Thanks. As someone who managed $48M in performance marketing, I was destroyed to see what musicians go through when I started promoting my album. I used to drop $2 CD's off at head shops because I thought stoners would like our music. People can complain about this all they want, but we believe this will be the PPC of music, and if I can play someone's music to 200 people for the same $2 that we spent giving it to one person, I will sleep very well at night.
I think this is a really keen observation.
this will really help, we will add few more questions to suite our client base. thanks for making this clear..
AFAIK the contest requires you to exploit an previously unknown vulnerability. (Contest rules link is down on cansecwest site.)

Which means even though Apple patched the 60 vulnerabilities the researcher used a one that was not known and thus not patched.
hm, I was expecting Readability-like styling, but it's a good start. A couple of feedback:

* make the upvote arrow HUGE.

* make the comments link HUGE.

* more contrast between color and background-color.
I've been thinking about changing the up arrow. Will play around with it.

Also, I just noticed that text within code is terrible.

> "PayPal doesn’t want their cut of tens of millions of dollars of revenue we project in the next two years. Any idea of who does?"

If you makes you feel any better, I offered them a cut of a projected billion dollars and they still didn't take it.

More seriously though, just go to your bank and open a merchant account.
Seems like a solution in search of a problem to me.
My favorite iPad app: Flipboard
Perhaps a per-query charge isn't optimal, but how else can a provider of a service equate supply with demand?

More load implies additional cost, and DNS providers are no exception; there is an incremental cost of serving a DNS response. Granted, it's small, but real nonetheless.

One could charge based on bytes transferred instead, but charging for bytes is functionally equivalent to charging for responses.
> None of the new stuff is new technology. They're amazing at selling something that's good enough for a lot of uses and leaving a lot of space for improvement in the very near future. If they would've included cameras and the accelerometer in version 1, and perhaps made it a bit thinner, version 2 would've been significantly less interesting.

Really?

I assume that you look back on every product's new version and say, "none of this is new tech, they could have shipped it in the last version!"

In almost every case, subsequent versions are driven directly by previous versions; nothing revolutionary happens. Was the dual core A5 ready for the first iPad? Was unibody aluminum manufacturing ready for the form factor and volume of iPad? Were the cameras sourced cheaply enough for the first iPad? What about 512MB RAM? Could all of this have been done in time for the first iPad? You have none of those answers, and I bet that most of them are "no."

Then you have something like the Smart Covers. Those are derived directly from watching what happened with the first iPad. No great cases came out, and people wanted to protect the screen. You ask, "Somehow the screen is all of a sudden the only important thing?" Well, yes, for many people. Myself included. I refuse to use any case, because most prevent easy docking, add bulk and are a pain. But every time I travel with my iPad, I am careful to stick it in a bag such that the screen is protected.
Grabbed one. I've been thinking about Chumby as a platform to build a stupid-simple radio interface for my grandfather. All he needs is a large clock and 4 or 5 clearly labeled radio preset buttons.
This is exactly what happens when you control the ins and out from start to finish. You can come up with the craziest of the ideas and innovation and pull it off without a lot of resistance since some manufacture cannot make it for you!
True, but it's amazing what some people in the low impact zone can actually do. One example that comes to mind is 'will it blend?'. They sell blenders, not very exciting, but everyone seems to know that phrase. Their YouTube videos pull in millions of views, and they're just tossing random gadgets in their blender. It emphasizes the quality of their product, and it gets people excited and linking to the content. They took a kitchen appliance and turned it into an internet sensation. Inspiring.

I don't know how other people do it; but I can deploy a Rails or a Django app in less than an hour without having automated scripts.

Of course, I do have a step-by-step wiki document, reminding me what to do.

But if you know the basics of configuring a web-server, and you're sticking to a preferred Linux distro, like Ubuntu or Debian, the process itself is pretty painless after the first time.

That said - it's pretty useful to have an automated process for getting a new web server up and running in case you're experiencing scalability problems.
Internet User Arrested For Linking To Other Sites
The mass of a Voyager RTG putting out 158W is about 38 kg (84lb). (It looks like Voyager used 3 of these RTGs.) Seems like they would be too heavy for your purpose.

It seems the Galileo RTGs were more powerful: 300 W in 56 kg (123 lb). This is still pretty heavy but maybe getting in there.
The benefit is reaped in the event a link is actually clicked on. That's why browsers do it.
For what it's worth, travel is a high-risk vertical and you're going to draw the evil eye from any competent operator if that is your focus. See also selling high end electronics or jewelry, among many other seedier business types.

Also FWIW: Paypal has processed close to 100k for me without complaint, and their review of my business for getting a merchant account was quick, professional, and successful. (Partly because I knew to avoid risk-adding activities like accepting yearly payments with a new business. Don't do that. Don't do aggregation. Don't do anything which envisions customers routinely receiving chargebacks or refunds.)

Very Asimovian, don't you think?

> The more information in a market, any market, the more efficient prices become. If informed investors start buying or selling based on privileged information, asset prices will rise to their “correct” level

This belies a clear misunderstanding of statistical mechanics. Markets are not purely random systems: they are regulated, and they are fictions of human imagination, unbounded by physical constraints. Two things come out of this: 1) certain pieces of information are fantastically more powerful than others 2) the author doesn't seem to realize that, in statistical mechanics, every particle, actor, whatever, has or doesn't have each piece of information. You introduce insider trading, and all of a sudden, you have a new variable, and every other particle, or actor, has a value of zero, except that one who has it. Privileged information actually decreases the information density in the market.

> Fraud will be exposed earlier. ... Enron ... If insiders were selling we would’ve seen a much swifter move down, and probable fraud exposed.

Pure supposition.

> Companies will either become more transparent, to keep the retail investor happy, or will themselves enforce secrecy rather than being complacent with the idea that the law somehow protects their secrets.

Show me how either of those necessarily falls out of any real theory of behavior, information theory, any mechanics, anything.

> More enforcement dollars will be used to uncover actual frauds such as the next Enron or Worldcom.

WHAT? ARE? YOU? SMOKING?

> Insider trading is almost impossible to prosecute and the government wastes countless dollars trying.

Um, actually, the SEC budget is definitely countable, and not infinite. It was 1.229 billion for 2011, and I'm pretty sure that wasn't all enforcement: http://www.wallstats.com/deathandtaxes/
