So, their biggest problems with Khan are that he doesn't go into enough detail and that he doesn't pick sides in the wars?

Wow, that -is- dangerous. He might teach children to think for themselves or something!

As for the Skinner Box, the internet is anything but. Yes, you tend to only see things you want to, etc... But there is nothing stopping you from seeing other things, and most sites will step out of your comfort zone quite a lot.

They honestly believe that somehow Khan's videos could become the -only- resource for learning about history. Not a chance.

Your first two paragraphs are reactionary garbage, but the postscript is actually a good point - while the Smart tested well in gov't and insurance tests, those tests involve vehicles of similar size. According to the link below, when tested against a Benz C-Class, the Smart got wrecked something fierce.

Cabose, taken on board your feedback. I definitely need to accompany the work with a case study page detailing what work was done for each project. In terms of keeping everything on one page, the initial goal was to keep it a one-pager (or at least try to), but I guess I'll need to iterate on that.
I trust that most who really don't want this story clogging up their HN will flag it. There are procedures for this sort of thing.
good low level backend stuff takes years of iteration under static business requirements. its also a well-understood domain with many prior implementations to learn from, and the 'companies' tend to be product-based so you have much less customer pressure.

teams reacting to changing or poorly-understood requirements (think enterprise and defense software contracts) have a much harder task. nobody has solved the problem before, nobody understands the problem, and project managagement is typically forced into waterfall in order to make sales, so its not like there's time to redo things that get duct-taped together, if the duct-tape holds.
America's own 'Lost Decade'
This makes me think of people who would try to "memorize" for e.g. science tests. They were ok as long as they could plug and chug, but they couldn't derive anything on the spot.

I'm wary of tickling my ego, but I recall not entirely seldom forgetting a formula, and so simply starting with other stuff and deriving it in the margin or on scratch paper. I think many of the instructors liked that, as well, as it showed a more conceptual grasp.

The comments thus far show exactly what is wrong with HN. HN has become an echo chamber where we all love certain people/companies/ideas and immediately dismiss any counter viewpoint.

Instead of immediately discrediting the linked article because they're "haters" or "threatened", try reading it and understanding their point of view. I love Khan's work and what he's doing, but at the same time the article raises some valid points. You learn a lot more by examining both sides of a story than being a fanboi.

Can anyone tell me why http://ipv6day.org is failing after a lengthy timeout, but http://www.ipv6day.org works? There are links to the non-www version in this article, so I assume it worked at some point.

Edit: Actually, I think SANS just linked to the wrong site. It should be http://www.worldipv6day.org/
As someone who tags a lot of friends on facebook, I love this feature. It was so painful to tag even 5 people over even a 20 photos album. I don't think this is any kind of privacy violation. Moreover, desktop apps like picasa have had brilliant image recognition abilities for a long time. The only thing I want fb to do is to give me an option to stop being tagged by apps without explicit permission.
How do you get a 7200 sided polygon from a 3450 ft circumference? That would be 6 inch wide windows. Steve mentioned them having a process to create the largest pieces of glass in the world... which look to be on the order of 10+ ft wide. That would mean at most 360 panes of glass, each turning a full degree.

Maybe it's not easily perceptible, but how much do you wanna bet they mocked it up and Steve was like "Yeah, you can tell the difference. It just doesn't feel right."
I'm ambivalent about this one.

On one hand, I hate banks. They treated me like shit when I was penniless, now that I have a couple to rub together they won't let me cash a check without trying to suck-up their way into some new type of account. Ocean Bank failed to protect their customer's money; I don't to see the difference between the FDIC protection afforded depositors in case of physical robbery and the protection that depositors should have from digital robbery.

On the other hand, there's no law, case or otherwise, that makes the bank specifically liable. So the judge has no basis on which to hold the bank accountable.

They "should" be liable, but it's an ethics issue, not a legality issue. I'm not about to expect a bank to be ethical.

This kind of thing makes me thankful for Wells Fargo. Their fraud/theft detection system is tops and has saved us from fraudulent charges in at least two instances.
Do they? At the time I was looking into it, there were many complaints that they didn't. (To be fair, Android has had some of the same complaints, but as I noted, the Android Market isn't the only path for an Android app.)

They might try-but why would Apple let them? They can just take their ball and go home. I couldn't find any hard numbers but a few articles I found were claiming that European sales make up less than 11% of total Apple sales.
Also, McDonald's like to sue people for using Mc-, kinda like Apple likes to sue people for using i-.

It's challenging to think for yourself when you don't have enough information to make reasoned decisions.
Not invented here (NIH) syndrome is poisonous to innovation. It's always embarrassing to watch companies like MS implement a particular "mainstream" feature in their own way just to make it different. This usually ends up awkward.

Which is precisely my problem with it. You build an app (at cost) and then you can't sell it because the turf you're playing on has restrictions.

They need to offer:

1. Certified apps from the app store which are approved via this process.
2. Apps which you can just download and chuck on with no Apple or carrier approval.

Ironically just like the Mac App Store i.e. you don't have to go there.

Oh and like Windows for the last however many years it has been around.
14 Ways To Optimize Your Ecommerce Marketing
As others have generally pointed out, 'intellectualism' isn't the problem. Instead, it's a particular brand of intellectualism that economically benefits from maintaining its established system. These intellectuals have little incentive to change their established position from which they profit. and they profit a lot. Generally, the traditional intellectual world can't keep up with the pace of the rest of the culture. We consumers and participants of intellectualism want cheaper, faster, more variety and niche. The current intellectual establishment benefits from the opposite.

Intellectualism is alive and well on the Internet. In fact this blog post and reaction to it is evidence. It's just that the traditional expert model doesn't scale into real economies. Many forces continue to work against it. As with other capital, intellectual capital will flow, like liquid, through the least resistant path. If one seeks influence and participation over intellectual topics, why would they spend many years going through the motions of attaining credibility and standing, when they can establish their presence much quicker along other routes?

All of the objects and roles referenced in the article (e.g. books, experts, etc.) have continued value, and they won't disappear, they will just be augmented by technology.

As the sun wanders across the sky throughout the day and year, every office will have some time spent in direct sun and other times in the shade. I'd probably choose the south side if I could so I could get extra sun in the winter.
According to the OP, the transfers did set off alarms in the bank, but the bank chose to ignore them.
I welcome opposing opinions but this itself doesn't present both sides of the argument, nor any context to the one example given, and sounds to me purely like a bashing exercise.
While this article does argue against Mr. Khan being the one and only teacher, it does not refute the effectiveness of his teaching.

This is exactly why every teacher should be delivering their course content in the same format as Khan. I am in the process of building a platform for any teacher to manage learning online in the same way that Khan has been so successful. I've been fortunate to be receive support on this transformation in education as recipient of the Thiel Fellowship: 20 Under 20. Visit http://ingenic.com to follow my progress.
When I was a 16 year old, my uncle hired me part-time to help him out with his stone and tile installation contracting business. As a regular grunt, I was happy to get that $10/hour and couldn't wait to spend it every couple of weeks just after getting the cheque.

Eventually, I met the owner of the shop that gave the contracts out to businesses like my uncle's and found out that he rakes in millions of $s annually. Now, this elderly gentleman walked around in very worn-out gardener overalls, talked to everyone on site, got to know each one of us personally, offered help, ate with us and drove a beat-up 1980s Benz. He was the first millionaire I met and quite honestly a model for a humble businessman.

My saving habits changed soon after that.
Programmers - good ones - are creative people. Creative people sometimes make poor entrepreneurs. Maybe you should let them decide for themselves what they want to pursue?
"We are the leaders of this new religion. We have faith that people connected can create a new world. Each one of us is a creator but together we are The Creator."

It all sounds lovely until the universe turns into a cold, dead cinder.

Seriously, making stuff is beautiful, and helping people is beautiful, but those don't add up to transcendent beings. If everything about us, right down to our deepest desires, is fundamentally just the motion of atoms, when the universe ends, it might has well have never happened.

I am a Christian, so I'm biased here#, but it seems to me that non-religious people keep trying to simultaneously claim that the universe is merely a semi-random collection of atoms and energy, AND that we can find transcendent meaning in it. You can't have it both ways.

#Then again, I think it's impossible NOT to be biased about a question like the meaning of life. We all want some particular thing to be true.

Check out Mondrian: http://mondrian.pentaho.com/ I used it a couple years back at a startup. It's written in Java and IIRC works (only?) with MySQL. Mondrian took a bit of work to get setup, mostly due to my lack of OLAP knowledge at the time, but once setup, it was pretty nice and fast. I think it uses materialized views for the cube data.
I'm actually working on a new project where an OLAP will be nice. Thanks for posting Brewery, I'll definitely give it a spin. OLAP's don't get much love, but are very useful for certain types of problems.
Possibly so. I should add that I'm not saying Cupertino should prevent Apple from building.

I lived in Menlo Park for a year before moving to SF, and was struck by how anti-development the Menlo Park and Palo Alto governments (and ordinary citizens) were. Perhaps Cupertino is different.

And, this proposal is pretty damn cool. Underground parking? That's fabulous.
For those of you who can't watch it or want a synopsis:

It's an inspiring talk about a guy who has dealt with multiple extreme health issues, like cancer and a lung transplant, and how people--connected by the internet--made it possible for him to get the help he needed to live. He's not saying that he worships the internet, rather that communication and understanding other people is what is best in all of us. In this sense, the internet is his religion because it allows him to have faith in the goodness of the world.
I don't think they CHOSE to ignore them, it was more that their response was not the best. (It trigger challenge/response questions versus the better option of a manual review)
Off topic, but WordPress has made blogs unreadable for iPad users. I can't even scroll through this article without the screen jumping erratically past many pages of content.
The article states that the banks automated systems were triggered for suspicious activity and the bank ignored them. One would think that at the very least that would make the bank negligent. Of course there is probably more to it than that.
I think it's quite easy to convince executives in an UX investment, you simply need to show previous results. "We did this UX thing for company X and it improved their bottomline with 20%"

But why would they want to burry their creativity in the code where few people will see it?
Most banks do have something in place for whitelisting transfers, but adding new recipients is often protected by the same regime that the Zeus bot controllers have already broken.
Why would there be such a thing? Would you create a service with that kind of value (and actual running costs) and give it away for free?
INAL, but in dealing with some banking software, the situation was explained to me as "Devil take the hindmost." In other words, no bank wants to be the one that implements the worst security, or security that is dramatically worse than "average," whatever that might be.

So for example if all the banks offer four digit PINs, there's not much need to offer six, eight, or ten digit PINs. But if a sufficiently large number of banks start offering ten digit PINs, no bank wants to be left behind, because at some point a customer will sue them and claim that they knowingly have lower standards.

This is purely anecdotal, but this is how it was explained to me when the product managers for a new product were trying to balance ease of use and accessibility against strength of security.

I disagree with your points about Apple - just because the vision is the only thing we (as the general public) sees. You cannot discount how many dead end products that are prototyped within Apple - and with their resources, they are able to build pretty much anything. From raw silicon to SOC to hardware prototypes of all kinds. Amazon probably requires the assistance of external parties to prototype the production of something like the kindle, but I believe Apple has the resources to assemble the iPad (at a low volume) in-house completely (ie from the silicon to the boards, to the plastic mouldings and final assembly and packaging.

I do believe that Apple also follows an internal "fail fast" strategy - it's just that we don't see the iterations.

I don't think Jobs is a Moses type see-all super visionary character - he just knows what's good - has "good taste". His lieutenants come up with product ideas to fit his vision, and he bashes the hell out of the bad ones. Kinda like what Google does, or Amazon does, or Bill Gates does (when he was around).

In that light, I don't think you can separate Apple from the rest of the "Gang of Four" - in fact, I think these ideas of "fail fast" and extreme agility, flexibility, and scale unite all 4 companies.

Just my opinion.
"switch true {...}" or "switch {...}"? really? So how would

Totally agree that more code reviews are needed. I guess then the question becomes, how do you teach someone to do a good code review. Code reviews come from experience I get it, so if you are a junior programmer then you get your code reviewed by someone senior. But there is also one very important part to a code review. It being able to give good advice to someone. Not to be over critical but to provide help that is actually going to build someone up. At a company I use to work at, they did this beautifully.

1) Every check in required a code review by a peer. In your commit statement, you specify who reviewed your code.

2) If a senior programmer wrote code for a feature that wasn't too complex he would get a code review from a junior programmer. The junior programmer doing the code review, learned what good code looks likes and second learned how to give feedback in a constructive manner as he was talking to someone with more experience than him/her.
I read it and normally consider myself pretty open minded. But then you read things like this.

"Here Mr. Khan stands exposed as possessing a historical perspective steeped in academia’s standard issue, postmodern, left-leaning narrative of cultural relativism, multiculturalism, and moral equivalence. "

And in my mind the author is exposed.

I am hoping that my son grows up being taught by postmodernist that don't present history as fact but as I believe it is – a perspective.

I would rather that my son grasp a few things about history and don't get the exact dates or details right. That he understands what history is as much as he knows what went into it.

So in my mind the valid points you talk about are nothing but the authors own idea about mainly his own field which is history. In other words his own interpretation – how ironic.

I agree that Kahn probably shouldn't be teaching history and I am sure with time that will be changed. But to claim that he is dangerous is simply missing the grander scheme of things.
Judging by the excuses given in the post, I'm going to guess that 'stress' is the answer. It sounds like a crazy place to work, even if it's making money. It could very well be that everyone decided to quit, and so it just dissolved.

The thing I remember was almost always missing in the education process I went through right up to the university was the big picture. A brief summary, a TL;DR, an idea, an answer to questions like "what does it mean?" or "why should I care?".

My experience with education is that for most of the time, we are being taught 'the form', not 'the contents'. It was after I've watched SICP video lectures that I finally understood many computer science concepts that I was being taught (read: forced to memorize for the exam) at university and even in high school.

I strongly believe in what Einstein said: "If you can't explain it simply, you don't understand it well enough." If Khan can summarize almost entire XX century into a 15-minute talk while staying correct with the facts, then that's great. It's what we call a 'high level overview'. It might be not sufficient, but it's a good start, as it constructs a skeleton which makes the details stick easier in our brains.

So much ssh for native IPv6. That could only mean we - few tech people - are more concerned about using it. In the future, with dual stack, I hope people will use IPv6 without knowing it. Maybe someday we will think about IPv4 the way we see IPX today: obsolete, nobody uses it.
A failing with programmers is we tend to focus on solutions rather than problems. Perhaps it's partly because, to be a good programmer, you need to immerse yourself in the code. Unfortunately, this takes your attention away from the bigger problem that the code solves.

In this article, it's interesting that though "Node solves a problem" is stressed as key to its success, compared with the many other JS server-side projects, they don't explicitly mention the problem, except obliquely at the end! (The problem is efficiently handling massive concurrencies in network connections.)

It's because of this short-sightedness of programmers that there will always be easy pickings available to anyone who actually looks at problem. Be a problem-person, not a solution-person.

It's true, there's no WWW without the Internet, but I don't think the Internet would be what it is today without the World Wide Web. Perhaps something else (something better?) may have come along in it's place, but it didn't.

I think the success of the web is it's ease of use, which has enabled anyone with an internet connection to contribute, and it's these contributions, both large and small, technical and non technical that make it mankinds greatest achievement.
I was having a discussion with someone about how much of our transportation issues would be solved if we were content traveling at <20mph. Electric vehicles could be much simpler because they didn't have to move at highway speeds. Travel would be significantly safer as well.

Think about it, how much of your everyday needs around within 5 miles of you? Unless you live in a rural area, I'd suspect 100% of your needs are within 5 miles of you. At that speed, you could get to anywhere in ~15 minutes inside of that 5 mile radius.

I wouldn't expect an article named "The Dangerous Mr Kahn" to spend much type discussing the upside of the Kahn Academy. Going into it, it's obvious that it is an advocacy piece written by someone who's not thrilled with Mr Kahn's work.

The OP's point is that hn is a discussion forum, which is most effective when the discussions are somewhat balanced. But since the Kahn Academy is a darling of this forum, this article is here just to be knocked down, and anyone not joining in is likely to be downvoted. That makes hn less valuable.
