> Note, too, that thanks to silly drinking laws in the U.S. there is a thriving industry in creating fake identity cards

Does this not happen much outside the US? In the US, the drinking age is 21. In most of the rest of the world it is 18, with a few scattered others (Japan 20, Iceland 20, 18-25 or illegal in India depending on region). From this, I'd expect demand for fake IDs for buying booze to be higher than average in the US because of the 19-21 year old market, but I'd expect the under 18 market to support fake IDs everywhere.

Even in the US, the impression I've gotten is that the under 18 market is where the majority of the fake ID for booze market lies, as that covers high school. Once you are out of high school and in college or in the full time work force, you can readily get booze regardless of age. In college, there will be 21 year olds among the juniors and seniors who can bring in the drinks, and in the work force there will be co-workers 21 and over to do that favor for you.

On the other hand, much of the rest of the world has been more accepting of technology to make IDs harder to fake. Could the US have a bigger fake ID market simply because it is easier to fake an ID here?

If the Knight Foundation made this grant last month, they would not get nearly as much press. Apple's Map mishap is a great PR opportunity to point out our dependence on walled gardens and promote alternatives.

That would stop patent trolls, but it wouldn't stop big corporation from patenting entirely obvious things and then suing the shit out of your startup.
Thirty years ago, when I was a six year old little girl, I had these:
http://www.brickset.com/detail/?Set=400-1
http://www.brickset.com/detail/?Set=402-1

They were my favorite. It never occurred to me that they were for boys, and I don't think anyone else tried to tell me that, either. I loved building houses and hotels with my universal building sets and for a long time they fueled dreams of being an architect, until I discovered engineering.

I know there has always been some gendering of toys, but I feel like we've regressed from where we were as a society when I was a child, and it's terribly depressing.
> There's virtually nothing keeping users on Twitter if a rival service popped up and their friends started moving there.

That's like saying, "There's virtually nothing keeping people on Earth if we develop cheap, reliable, faster-than-light space travel."
"On the same day the company's stock plunged 33 percent, to $3.39; by the next day 75 percent of Knight's equity value had been erased."

So in the example you linked, a computer algorithms went crazy, and anybody invested in Knight Capital got hosed ... as did anybody elsewhere in the market that reacted to that instability. Not exactly a convincing argument that it can't or won't happen again potentially on a much larger scale. You basically confirmed my point.
that helps when travelling in a car but if backpacking or on a plane, bus, train, or in less developed cities plugs can be rather difficult to find.
Manufacturing: The latest chapter
What we do know is that Google raised their general prices for map access since the original deal with Apple was made. If we assume Google also wanted to increase the rate for Apple's access, it seems logical that they would be upset that they lost a multimillion dollar deal.
Thats true. It is.. a rather complicated situation. I suppose it has to go one way or another especially with such a disruptive idea like kickstarter

It's got a very strong design which you executed well. It's quite polished. The rails part is hard to comment on because we can't see your code - but from the url structure, it looks like it worked well for you.

Having said that, I'm not really a fan of the design overall because I find it distracting from the actual content. IMO, effective design should help to focus the user's attention on the content, not be part of the focus in and of itself. I'm just not a fan of overly skeuomorphic designs in general for that reason.

The Tips & Tricks animation on the sidebar is also very distracting.

Same here. The difference is that the motivation that caused Aaron to break the law is a genuine desire to improve the world -- and that's what advocates for Aaron in the arena of public opinion should focus on.
Your original point was:

"The market has changed in a way that an overwhelming number of external factors can have a negative (or positive) impact on that company's share price"

Knight Capital loosing a ton of money was not due to an external factor. It was due to an internal factor. The fact that they (apparently?) accidentally deployed a bunch of test code to production. Oops!

If you find Quantblocks interesting, you should also look at Quantopian. (www.quantopian.com)

We're geared a bit more towards programmers. Rather than use blocks, our members develop their algorithms in Python. We have an in-browser IDE with a lot of smart auto-completion.

A few of our nifty features:
* free access to 10 years of by-minute historical data for all US stocks
* the writer of the algorithm owns the algorithm
* batteries included - all of your favorite Python math and science packages including Pandas and NumPy
* a robust backtester that models slippage, commissions, risk metrics, and more

We also have a community of quants and programmers who like talking about this kind of stuff. People share code, give advice, ask questions, etc.

Full disclosure: I work for Quantopian!

Happy hacking,

So you're saying creating a rival service to Twitter would be as hard as creating faster than light space travel?

All I'm talking about is gradual migrations like the ones from geocities and myspace. In the case of those services users had a lot of content they'd created that they had to leave behind. By it's ephemeral nature Twitter has very little of that.
What percent of developer frustration falls under "We're making money off Twitter without paying Twitter anything and now we're upset that we can't do that anymore"?
go is very fast(it's aimed at somewhere between C and C++).

it's a systems programming language, you supposedly can do anything. there's some companies already using it like soundcloud. it's awesome for api's because of it's speed.

also, it's a well thought language with many different decisions from common languages, it does not have exceptions and so on. it's an awesome language if you want to expand your mind.

otherwise, i would pick clojure.

Well then I redefine the truth to be anything that is not 100% false, therefore I can always tell the truth even when I am lying according to 99.9% of the population.
For reference, because this statistic boggles my mind, with an average class size of 30, the average expenditure per classroom is roughly three hundred thousand dollars.

What is wrong with this country's public education system when we can spend three hundred thousand dollars on a single classroom and children can't learn fractions?

I disagree that the problem is teacher salaries. I would posit that teacher salaries are good and fair in my state (and low in others), but that there are many teachers out there undeserving of their jobs let alone their salaries.

The problem is bloated administration, vast overspending on technology, underqualified teachers that cannot be fired, and the impossibility of supplanting entrenched, malignant teachers unions.

What can be done about these problems? Well, not much really. The upper middle class is taking their school taxes on the chin and putting their children through private schools, the lower middle class doesn't have the weapons or resources to fight the public school bureaucracy, and the teachers union has a vested interest in doing what is best for teachers, not what is best for students.

I am very much in favor of unionization, however time and time again we've been shown that school boards cannot be trusted to broker a good deal when they're paying for things with someone else's money, and unions aren't going to do them any favors.
This is the 2nd part of the interview mini-series with Ramit Sethi on starting a consulting business, though we both talk products in this interview as well.

I'm happy to answer questions, as always.

P.S. I normally try to space out publishing things, to avoid a) reader fatigue on my favorite topics and b) imposing on HN goodwill by showing up on the front page too often. That said, the next two weeks are going to see a few more posts on the blog than usual. Several independently managed processes, with varying numbers of steps, people in the loop, and pipelines, all decided to terminate roughly simultaneously. I apologize in advance if it's mildly irksome -- believe it or not, it is the exact opposite of a planned media blitz.
"only 2% of the population qualifies for it"

Do you believe that this is true?

He said so, at that time probably not a big deal to put it on a resume. These days, I recommend against it, as soon as most interviewers I know see it, it's suddenly high noon on the whiteboard to prove the interviewer is just as smart as the Mensa person.

Edit: I'm not in Mensa, I've just seen how interviewers react to it. Petty sure, but I'm talking programmer interviews, people often look for reasons to exclude someone.
I'm putting together a fun little video this weekend where I'll be reading aloud (and toasting to) emails from people who have read my book (http://doubleyourfreelancingrate.com) and are now charging more.

The dozen or so responses that make up this upcoming video and the corresponding shifts in worldview are directly inline with everything Patrick and Ramit have to say in this interview. Here are my takeaways from these testimonials:

* Most people price themselves in the same way commodity markets price corn, oil, and hogs.

* Fear keeps us from breaking away from market/cost-plus pricing to a pricing strategy that's focused on the value we deliver to our customers.

* When you focus on why people hire us (to increase revenue or cut costs) and approach everything with that end goal in mind, you can dramatically increase the value you produce and the cost for that value. Commodity pricing is thinking "I write Ruby for my clients" or "I setup Wordpress sites". Pricing based on the value you deliver is "I help businesses increase profits by minimizing the amount of clicks the sales team needs to make in order to process a new transaction."
I love updating my Mac. Each new version makes it better, and problems seem to be minor and rare. It’s worlds different from the Windows upgrade rat-race.

Huh? I am hoping that my sarcasm radar didn't pick this up. But, most software still runs perfectly fine on Windows XP. In fact, all of our university's Windows computers still run Windows XP (with up to date Creative Suite, Office, SPSS, etc. versions). Since Windows XP was released in 2001 (!), that's eleven years and counting.

What rat race?
I think I understand and don't think that you are necessarily wrong but I'm not sure it is a particularly useful way to look at the world.

Enron was famous for booking predicted lifetime profits based on the ideas that they had and look how that turned out. It isn't logically wrong but it probably is too hard to do realistically, not just predicting the profits in the first place but updating them with circumstances.

If your person had his bolt in the blue and became richer the moment he/she heard about a competitor launching before them with a similar idea would instantly become poorer (as they wouldn't have the market to themselves) and they should remark their book value.

BTW without capitalised sentences and in stream of thought style I found this really hare to read. I suggest you work on the presentation before explaining it to anyone else.
I don't think I quite followed the step where he/she writes "i^4 = 1", where they are relating rotation and the natural numbers. The RHS is theoretically the concept "identity under rotation". Why should it be be the same as the natural number 1?

Maybe I missed something in the explanation. Can somebody explain?
The overall message that I need to be the one to remove a product from its packaging and that if anyone else does it, then my whole experience is ruined feels whiny and entitled to me.

I get where the guy is coming from. I appreciate quality of experience as much as anyone, and each time I purchased an iPhone in store (three times now) it was at an Apple store and they did it the "right" way. I would even feel a bit annoyed if I didn't get the "proper" experience, but I'm mature enough to understand the magnitude of the infraction, and I wouldn't whine about it in public.

This is unboxing a goddamn phone, not your wedding night.
Unlike some types of software, browsers actually do suffer bit rot. Running an old, unsupported browser is dangerous.

If Google isn't going to support (i.e. provide security fixes) for the branch that supports older versions of OS X, it would be irresponsible to let people continue to install it.
You're more than welcome to disagree with Kurzweil and his theories, but at least do it properly.

There is an implicit start from the unit vector 1. i (really 1 * i) is a 90° rotation of that. i^4 is four 90° rotations. Rotate anything four times and you've rotated it 360°, ending up where you started at 1.
I had no idea they were run by the same people.
Hideho Patrick ... the first one was great and having read through your blog a couple times already, I don't think fatigue is an issue.

I hadn't really thought about it but it's interesting to me that I find myself more or less fatigued based on the writing style.

In any case ... thanks for sharing! (and yes, I'm an old BoSer)
Ridiculous metaphors FTW: "You know, the twice or often thrice yearly events that bring everyone out to Cupertino, where they stand in line and contribute a few licks to the collective rim job the press loves to give Apple."
I would say, because they are obvious.

If you had just watched an episode of The Jetsons and then were presented with a global communications network attached to computers with video screens, live video communications would be about the first thing you would think of. If you had also watched some adverts during the episode however, you would probably come up with live video porn, and maybe Amazon.
I am pretty sure both of my little brothers each had at least one Ken doll, at least one Cabbage Patch Kid, several Care Bears, etc... all kinds of toys that would be considered more gendered today. The eighties, man, they were a different time.
Look, you might value something different that I do. I value great design and great experiences. In this case, Apple has designed a great user experience with a new product. If you believe that the iPhone is just a phone, then I don't think you can appreciate the thought that goes into each and every piece.

I think that Apple has personally touched me because it's values resonate so well with my own. To create things that are simple and wonderful to use, thought through to every minor detail. The careful precision that you don't really get with any other smartphone maker at the moment.

When the iPhone is treated a coffeetable book in front of the owner entering a 2 year contract and paying $200-$400 dollars, don't you see the harm in that?
I feel like you played techphrase roulette to come up with this idea.
I clicked for the headline but won't sign it because because it would mean I still have interest in using twitter as a developing platform and I don't.

I rather just ignore it and let it fade away and hope it to take all it's egotic celebrities, teenies, morning-tv-moms, smartasses, attention seekers, ads, media & marketing businesses, and all the rest of waste with them, feeling good!
I mis-spoke. I didn’t mean “rat race.” I meant process. I am not saying there are too many Windows updates; I am saying you are far more likely to have problems after upgrading Windows than you are a Mac. For example, I literally cannot install Windows 7 on a laptop I acquired that shipped with Windows Vista. HP simply does not make the required drivers. It even seems the optical drive will not function correctly during a Win 7 installation attempt. It’s mind-blowingly sucktastic.

There are Macs too old for the latest OS X, yes, but they are pretty old, and were able to keep up-to-date for years.
I don't really like seeing things phased out that still work perfectly well. But, selfishly I'm glad Chrome is doing this because our main software product is becoming impossible to continue supporting 10.5 as well. We already planned to phase out 10.5 support at the end of the year, but I think with large vendors like google this will hopefully make people realize that we sometimes need to upgrade in order to keep up with modern features that everybody expects.

Thanks for responding here Jeff. The license on https://github.com/appcelerator/titanium_mobile is Apache 2.0. How can you possibly ask for money from a developer who used Apache 2.0 code? It seems like a black and white issue and that you are in the wrong. Please address the Apache 2.0 license in your response.
get's?
Say this catches on and you have two push requests, which one are you going use, because odds are you need to merge the second one by hand. This is not practical, but at least you get a fork.
My point was that external factors can have an impact on the stock price of an company in ways that previously hadn't been possible, and I cited HFT as one of those factors. You cited Knight Capital whose "internal factor [...] (apparently?) accidentally deployed a bunch of test code to production" resulted in "trading activities [that] caused a major disruption in the prices of 148 companies listed".

So yes - in this case, the internal factor of Knight running a flawed algorithm turned into a very real external factor for those 148 companies, as well as anybody else whose trading was impacted along the way.
I'm sorry but don't see what that has to do with the misplaced sense of personal entitlement.
Google derives their primary revenue from advertising. APIs allow developers to sidestep advertising in displaying Google's content. Ergo, it is not in Google's best interest to allow easy free access to their content, via an API or otherwise, in a place where they cannot control how the content is displayed.

I don't completely agree with this reasoning but I can see why they don't just throw build APIs everywhere.
Have any specific ones in mind? I'm definitely open to this. Not happy with the readability
While I can understand the excitement of opening up a shiny new thing, and agree somewhat with your assessment that the rep messed up (forgetting the charger and haphazardly handling your new phone), I don't feel that your proposed solution is in any way viable, and might even end up pissing people off more:

2. The rep retrieves the phone and hands it to you to check.

3. The rep then encourages you to open your iPhone and shares in your excitement.

4. Once the phone is open, the rep then respectfully asks to take the phone and goes about his business. He leaves the protective covers on the phone, and lets you take them off at your own will.

So, here you are on iPhone 5 launch day, you've been waiting for hours, and the store is absolutely packed with people. How does this process work out? Do you lose your place in line while you open your phone and play around with it for a few minutes (even though it doesn't do anything yet)? Is the rep supposed to stand there and wait, 'sharing in your excitement' while the lines grow even longer? The reps are at work and they are trying to get these rabid fans their iPhones as soon as possible. This guy was working quickly because the line was out the door and he's trying to do his damn job. I'm guessing that when you work at a phone company, even the thrill of a new iPhone loses its charm pretty fast.

I can see allowing a patent on software to the extent the invention incorporates a truly novel and interdependent physical component. But plain software patents are, for the most part, bogus and ought to be outright eliminated. There is no dearth of software innovation, and the litigation is twice as expensive as development.
Most recruiters don't want to help you. Helping you is just a by product of helping themselves. I had one that demanded a text document resume (instead of a PDF). A few days later he sends it back padded with a bunch of nonsense (including a lot of false skills).
They don't. I've used Appcelerator for a number of projects that are now on the App store(s) and haven't ever worried about this. The source code is on Github under the Apache license as you mentioned. This is enough for me and my lawyers to not worry about it.
Right, if you are devoting time being average and not growing at X when you can be grow and be extraordinary at Y, it's time to move from X to Y.
This isn't necessarily entitlement, it could be a combination of 1) having paid for a product and wanting to be the only one handling it and 2) OCD.

Sometimes a cigar is just a cigar.

Though there is clear evidence of some idol worshiping going on here with the author of this peace (in regards to Apple). But IMO that's another story.

Personally, I'd want to open the box myself without anyone else handling what's clearly mine. Especially not some lame ass that couldn't care less if he damaged the device.
The share price for those 148 companies barely moved.
