Do you think this is deliberate on Apple's part to force a change in publishing contracts?
Hmm. Finding maths so dull was probably one of the main reasons that I didn't peruse a degree and CS or physics. Which was a disastrous decision for me personally. Not that I just couldn't face studying anything unexciting per se, but that I (wrongly) assumed that if I didn't find something interesting then i could never be sufficiently good at it. At high school I was 'streamed' into one of the lower tier math classes, which I resented - result was getting a higher mark in the end than most of the top-tier students. But perhaps I would have been better off in a more advanced class where I'd struggle more but at least find the stuff interesting.

Anyway my point is it's a shame to turn people away from maths by offering such stale curriculum.

What do you consider "large value denominated" and where did find out what the breakdown was? In my book "large value" in a 1.5 mil heist would be $5,000 and higher. My guess would be that most chips were $100, $500 and $1,000 chips. But AFAIK, Bellagio hasn't released any of that information.

That wasn't there the last time I saw it. And I tried every key. Looks like they changed it. Thanks for the hint!
I think you missed the point.

Most people find first year of computer science very hard. For me it was easy, but plenty of people found it hard, and I think many people changed majors because of that.

Now imagine if it was mandatory in high school. Teachers probably won't understand it much. The curriculum will probably focus on "formula"-like things (perhaps, patterns?), syntax maybe, and a whole bunch of boring details, and ignore the most important part: problem solving.

Students might study (read: memorize) all kinds of functions for doing things.

Grade 8: loops for sorting numbers, loops for finding min and max numbers, loops for calculating factorials. for-loop synatx in C. for-loop syntax in python.

Grade 9: recursive functions for sorting (e.g. merge sort), recursive functions for calculating factorials, recursive functions for finding min/max numbers in a list.

I only realized this very recently, but math has a lot in common with computer science. Its core is about problem solving. Unfortunately, that's not how it gets taught in high school. In high school, math is a set of arbitrary formulas you have to memorize and use to "solve" arbitrary equations. We were given a lot of "practice problems"; they were the most boring thing in the world. They didn't teach you anything; their only purpose is brush up your muscle memory so that when you see a problem of the form "A B C" you know which formula to use and how to use it.

I'm having trouble understanding the technical possibility of chips being deactivated in this scenario. I see from the police report it wasn't, but just wondered anyway.

If someone grabs X chips, where X is quite a high number, and walks out the door - are the numbers registered as they go, and can be deactivated thereafter?

Can a high value of X be scanned and stored by RFID technology? How are legit walk-outs and stolen separated?

Also, I see mention of the technology "Spotting a dealer accidentally shorting a player" - is this technology that granular that a transaction like that can be logged accurately?

Just curious if anyone can indulge me.
Precisely so, but that's not testing, it's repair. You've just rolled back from a production problem automatically. The user still saw the problem.

Sorry if this seems rude. You're definitely way ahead of the game, but you're not addressing the thing that I'm talking about.

I have to echo some of the comments from TFA. If you mark it, no matter how, the curious are going to explore it. Even if they understand the danger they may unearth.

The exception is if you have an advanced culture that stumbles upon it. They'll know what it is and perhaps how to deal with it better than we do.

I have to admit that I find it hard to imagine an alien mind not having curiosity or the urge to explore.
Or maybe a sort of AI enhanced service that automated the 'legal hacking' involved in navigating the world of patents. Like as well as writing unit tests for your code, you write 'patent tests' which allow the search tool to determine if you're code/product is infringing any patents and if so how to avoid infringement.

This is what happens when you make a headline for an article, put a video in it, mislead the answer with a bunch of garbled text and then expect people to draw conclusions about it. Everyone's first inclination from the headline is "OMG what does Fred see in Pandora/Groupon that I don't?!" Don't believe me, look at the first few comments of the article.

Funny, I never realized that's what the symbol denotes.
Even if they're are RFID's in the chips themselves, the table still has to have scanning equipment to read the payouts and that's expensive. Not all casinos use that to track play and payouts. I believe Bellagio uses old school tracking with pit bosses going around writing down your play from time to time.
I'm a SysAdmin, not a dev, so things are somewhat different; still, the marketing is probably pretty similar.

I wrote a book about some of the things I more commonly SysAdmin. By far, this was the best marketing I've ever done. (It's also the most expensive marketing I've ever done. No-starch paid to have it printed, but god damn, that was a lot of work to write.)

Now, as for an online presence, in my field, being visible on mailing lists and the like is pretty important. A nice website? much less so. Of course, if you are a frontend dev, the opposite probably applies.

Eh, I do think that contributing patches back is pretty important. Good decision makers consult good technical people before making such a decision, and having some patches on public mailing lists shows that you know /something/ (which is usually good enough for a SysAdmin. Nobody expects me to be able to re-write apache, but I am expected to sometimes make some small change to mod_auth_*)

Still, writing a book (and having it published by an established publisher) might not be the cheapest way to reach decision makers, but it's one of the more effective ways to do so, I think.

I think this is meant to deal with non-SSL content hosted outside of your own domain, right? As the earlier posted pointed out, you can just get an SSL cert and DIY much cheaper. If it's to deal with non-SSL content hosted by someone else, I'm assuming you're proxying the content?

Might you still get those errors anyway if some javascript on the page makes a request for non-SSL content?

> Eliminate patents for everything except FDA-regulated drugs.

I agree the patent system has its problems, but I'm curious: Why that one exception, but no others? What about, say, medical devices? And then where do you draw the line -- and why there and not somewhere else? (These are issues that legislators, lawyers, and judges have to deal with all the time.)

A really good read. More proof that a great team is worth more than a great idea.
Gruber recently said that contracts with publishers are generally set up in a way so that they get about 70% from all revenue. This would obviously make it impossible for Amazon to sell books on the iPad. (The publisher taking 70% and Apple taking 30% leaves them with nothing at all. Increasing prices, even if it were possible, wouldn’t help.) That's obviously not a workable situation, if Apple doesn’t change anything Amazon will just stop selling books on the iPad. (Gruber speculates that Apple will drop its cut for at least some in-app purchases down to about 5%.)
The downvoting (not by me, BTW) is probably because you didn't understand the math and simply appealed to complexity. Your appeal to complexity was both incorrect (pressure = sum of hidden variables, g = sum of hidden variables, complexity is equal) and also irrelevant (Shalizi's argument is against statistical reductions and is independent of complexity).

My objection is not to the fact that Shalizi is hypothesizing a microstructure to g. Here is what I had to say about that part of the article: "It's a great article... Thompson's model makes a specific prediction about g - it should be normally distributed. So overall, I agree with the author's scientific argument: g is very likely to be decomposable into subfactors."

My objection is simply to the term "statistical myth". By Shalizi's argument, macroscale variables which abstract away an ensemble of microscale variables are a "statistical myth". Depending on your philosophical axioms, that's a fine thing to believe - but we should acknowledge that if you believe this, then you also believe pressure is also a statistical myth.

As for the new points you raise:

1) G is a tautology if you deliberately posit a family of normally distributed variables with positive correlations. In fact, it's a tautology if you posit a family of strongly correlated normally distributed variables of any sort (the factors might just have negative components).

This does not, however, explain why performance on various tests is correlated. G and multifactor models are an attempt at explaining this. Thompson's model (which has g built in) is another.

2) Indeed, we don't really understand it. For a long time we didn't understand pressure or temperature either - all we understood was the macroscopic effects. So what?

3) You are clearly speaking about something you don't know much about. If you want to argue that linear models don't work because the data is nonlinear, do it. You haven't. Neither did the author.
This is a ridiculous waste of money. What happens when there is a major continental fracture/disaster in the next 10000 years putting the sites possibly thousands of miles in any direction... I know it isn't likely to happen but putting this refuse inside the planet probably isn't a good idea.
First, you'd have to show that innovation is being blocked in America, considering that most software innovations come from there.

While in need of some tuning, IP laws seem to be working as advertised: you can't release a product that copies 90% of another product, you actually have to innovate.

Look at Android: they had to navigate around dozens of Apple patents and they still did fine and they have come up with an impressive set of innovations.

When plagiarizing is outlawed, you have no choice but innovate.
I don't have a problem finding things I'd be interested in. Far opposite. I have the problem of not having enough time, energy and money to act on all of them. Therefore this feels like a solution without a problem.

> One of the foundations of America's success in the earlier years (up to the beginning of the 20th C) was its general disregard for IP laws.

Uh, you should really read up on America's early economic development. Its success has very little to do with IP laws.

And to counter your claim: look at China, which has no IP laws. How much software innovation do you see coming from there?

Yup, zero.
>When designing something as complex as a car, form and function need to be equally considered every step of the way.

That's not how apple did it.

Apple took an existing operating system that really only considered function, freebsd, and then built something pretty on and around it.

I mean, I'm not criticizing apple; they followed the rules and built something the FreeBSD team could not have built, and most FreeBSD guys I know are pretty happy with what apple did.

If you were going with the apple model for these cars, what you'd do is first build ugly cars that take an expert to drive that are extremely fast, utilitarian and reliable, but licence them under the BSD licence.

Next, have some for-profit company take the design, put a lot of effort in to making it look nice, add features that make it easy for a novice to drive, and then sell the new cars for a whole lot of money.

I mean, it's a great idea, but you need the FreeBSD of cars before you can have the Apple of cars.
Vivek has already done the research, and that's where he gets his 90% non-funded figure. If you want details click through the link provided in the TechCrunch article. The methodology is described on page 7 and seems sensible:

This isn't an attack on you or YCombinator. It just doesn't make sense to critique Vivek's points by saying that "nearly all successful startups have investors." Because apparently they don't.

It wasn't about me, I've been doing sports my whole life but never tried weight lifting. Before I spend my time writing a reply, please answer this question. Do you think that if we all lived in the same environment, had the same diet, did as much physical exercise and all other variables were the same except our genes, we wouldn't see a difference of 1 foot between people or a difference of pounds of muscle mass? And more related to the article, we wouldn't see a difference in intelligence?
Great points, but I'd like to hear a second opinion. Anyone tried this? Some of the most innovative stuff is happening in some of the most lawless places almost by definition. I've had the inclination to try some of my personal projects outside the country on several occasions.
I wouldn't mind it because in bed, I don't even hold books. Instead I place it on the mattress and lean to it. So the weight is unimportant. What's imporant is that its flat and relatively short like the size of a large tradeback novel.
Making the spot stand out in a spectacular way is pretty much guaranteed to attract visitors. Why not just make it as plain as possible above the ground? Then you can bury warnings at various depths, just in case someone decides to dig there by pure accident. (10,000 years is too short of a time for significant tectonic activity.) If they have the technology to dig 1,000 feet deep, they'll probably be smart enough to decipher something like the Voyager Golden Record.
I really liked that. All the uncertainty / lack of specific and detailed plans is something I can definitely relate to, it's nice to see someone as successful as you guys never knew exactly where you were going till you got there.
My oldest son has dyscalculia and just sucks at crunching numbers. He had a terrible, terrible time with math in public school and really hated and dreaded the subject by the time we pulled the kids out to homeschool. It was clear to me he would not be able to memorize his way through math like his mom had. (I was in my thirties when I discovered some of this stuff had actual uses. sigh) My top priority for math with this child was to teach him "math is your friend". He's a science geek (which is tough when math is not something you are good at) and loves physics. He taught me most of the physics I know (speaking in little words and repeating himself a lot) when he was 14, which stood me in very good stead when taking certain college classes later on.

A few things we did:

Chapter books, full of discussion about math and light on formulas.

Let him choose a statistics track over an algebra/geometry/trig track. (We did some algebra and geometry but not too much.)

Read about halfway through "A tour of the calculus". I dropped out of calculus my first quarter in college and never wanted to see the subject again, after having been inducted into Mu Alpha Theta in 11th grade. He would spend an hour on this with me because it was the only math that made more sense to him than to me and he was happy to watch me get a headache (which I played for all it was worth). This book was chosen because he loves physics and calculus is the math of physics and because calculus really requires you to learn all that algebra/geometry/trig stuff he wanted nothing to do with. I knew I had won the battle when he was whining and complaining one day about not wanting to do math and then got all perked up at the idea of working on reading a couple more pages of this book with me.

We also did "fun" stuff, like card games and such in place of workbooks and that did have some value. But reading part of "A tour of the calculus" was the single biggest thing I did to get him past this mental and emotional block. Which I guess largely agrees with this article, though perhaps framed a little differently.
I'll listen to this song every time when I get bored on Grooveshark.
The MPEG 2 patent fees accounted for a "crazy amount" of the price of a DVD player as prices fell, which caused Chinese manufacturers to revolt and threaten to create their own rival standard. It costs $20 to add MPEG2 handling capability to Quicktime.

The MPEG4 part 2 and AAC fees were such a "crazy amount" that Apple (!) refused to release Quicktime 6 as a result until the fee structure was changed.

Expecting the owner of IP to extract maximum value from it is hardly a conspiracy theory.
