I was going to add this as an edit to my earlier comment, but I'm on a crappy connection, and was too late. Let me expand on my comment.

I think this is a brilliant idea, and it seems to be well executed. I don't have the necessary hardware to run it, so I haven't played with it, but it looks to be a wonderful game based on algebraic manipulations. I, along with everyone else, expect and hope that it will engage players and allow them to learn the rules and skills of such manipulations.

And probably that's a good thing. Let me try to explain the underlying reasons for my sense of unease, as best I understand them.

Firstly, I am concerned that this will merely enhance the sense that math is simply arbitrary manipulations with neither meaning nor motivation. Many of the kids I tutor can do the manipulation, but don't get the point, and never connect it with reality.

Next, some of the kids I tutor can't do the manipulations without making stupid errors, and I can't help but feel that even after practising with this, they will still make stupid errors. Link that to the apparent meaninglessness, and there's a recipe for frustration.

Thirdly, this doesn't help to connect the creation of equations with the physical problem to be solved, and it doesn't help interpret any final answer. These are the steps that the kids I deal with simply can't do.

Finally, as someone commented, this isn't intended to be the whole and entire course, and it's supposed to be just one tool to help one stage, and to be built on and leveraged by the teachers. I've lost count of the number of wonderful tools and ideas that I've seen whither and die because the teachers can't make use of them. In some cases the teachers don't really understand them, but I would hope that fate would be avoided by this.

So in summary, I think this is a wonderful tool, and it has the potential to be a fantastic aid to learning. I am deeply uneasy about the further divorcing of algebraic manipluation from any sense of meaning, but I look forward with interest to see if it can be used in a meaningful way.
If your "implantable pacemaker" records a bunch of vital information about my heart for years, then it is not a simple "implantable pacemaker", it is an information processing device, and the sensitive information it produce and store is my own, and allowing you full control on it is a danger of potential alienation that must be mitigated.

As we do not currently have a better way[1] to ensure there will be no misuse of the power brought to you by controlling the way this information is generated, processed and stored, I would much prefer this heavy responsibility to be split between three different providers (information producer, processor, storage) communicating together according to open formats.

If your pacemaker is a piece of hardware with no sensitive information stored and not connected to the outside world, then I would not consider its "software driver" to be an information processing system (ie "real" software), and there would be no need to split responsibilities in this case. This should also answer to the "micro-wave" objections in other answers. And yes, I change the definition of "software" a little bit, so it do not include single-minded commodities drivers.

Actually, "software" is too wide on one side, and too narrow on another. A big company like Google should be understood as a software company. For me, they do not cross the line if they build their own servers for internal usage. They do cross the line, however, when they buy Motorola. The gray area would be the Nexus line and Chromebooks, which is ok to me if these products can be considered as real-life experiment for new software concepts, but not ok if they become mainstream products sold by the million of unit and if Google installs itself in a long term hardware producing activity, in parallel with its enormous presence as the software gorilla.

Once i spent a week researching Lotteries on google. Days after, i was getting an almost constant stream of ads for the National Lottery. If anyone were to have used my computer during that time, they might have been puzzled by this and though "Whoah! Is this guy a gambling addict?".

Just imagine if i was researching something slightly more taboo. Someone could easily jump to the wrong conclusions.

I might have nothing to hide, but it certainly isn't right that my information is being used to generate a potentially scandalous false picture of what i might be looking for.
As a word of warning, I should caution you that you are entering a domain filled with administrative red tape and bureaucratic obstacles. Regardless of which area of medical workflow you are targeting, I think it would behoove you to "team up" with someone on the inside, such as a doctor or someone in an administrative capacity in a large healthcare organization. The functional guidance provided will be a great boon, both in cutting through red tape, and by allowing you to focus on the technology aspects of the solution you are trying to build.
That's what .gmbh is, in German, so that sounds about right.
>rather than with the deep satisfaction that comes with understanding

This may not be a problem. For me, that satisfaction happens when understanding makes the world make more sense, less arbitrary; like you just got let in a joke that's been puzzling you for years. This is just one more thing that will make sense later. If anything, it'll enhance the effect.
>but at the end of the day if you really want to precisely say what it is you're talking about, it's symbols

Hear hear! I'd go one step further and say its ALL symbols. Any associated real-life meanings that help a human intuitively understand the equation is purely coincidental and actually a distraction. I've repeated this argument ad-nauseam : http://news.ycombinator.com/item?id=4085558

Don't know who it was ( Martin Gardner ? ) who once said three dinosaur plus two dinosaur is still five dinosaur. The implication is that symbol pushing and symbol manipulation is way more fundamental than having humans around who can associate three and two with human artifacts and then add them to satisfy their intuition. The dinos will add up to 5 regardless of the human intuition.

> So what? Vegetarianism doesn't work that way.

Yours doesn't, perhaps.

Many folks are vegetarian for ethical reasons, and many of those people still really liked the taste of meat. Letting them experience the tasty without the ethical issues seems win-win.
Thanks! That makes sense. I could be wrong, but I think a lot of this is because FCP 4 doesn't speak h.264 and doesn't take good advantage of the hardware. When/if you can switch to FCP X or a modern competitor (not saying that's an option yet, necessarily), I wouldn't be surprised to hear that most of these annoyances go away.
I think you overestimate the implied value of going directly from high school to 4 year college to potentially graduate school. Taking a year or two off in the middle of that to explore things OUTSIDE college, particularly if being paid $50k/yr to do it, seems perfectly reasonable. If you have great traction in what you're doing, stick with it -- otherwise you still have the option of going back to school.

So what? Vegetarianism doesn't work that way

I know plenty of vegetarians who like bacon or meat-flavoured potato chips/crisps[1]. That doesn't mean that every vegetarian should or does like such things, just that there are lots of different types of people out there.

have you tried Quorn

Admittedly, I'm a meat-eater, but I have always found Quorn profoundly disappointing, and very expensive for what it is. When cooking, say, a vegetarian curry, I usually substitute sweet potato in its place.

[1] I hasten to add that the chips/crisps in question are, as far as chemistry is concerned, 100% vegetarian ;)

They adjust IQ scores for income? I missed that.

It has nothing to do with political correctness - it was literally the purpose of general intelligence tests to justify exclusionary immigration, racism and eugenics, and they were designed (or redesigned in some cases, such as when blacks in the military scored better than whites) to do that well. It reified a general intelligence concept that has no actual evidence, and justified that with factor analysis, the leading tool of statisticians for creating a single thing out of a maelstorm of complicated, interdependent factors by just pretending that they are linear.

See: https://en.wikipedia.org/wiki/The_Mismeasure_of_Man

IQ tests correlate far higher with pleasure reading in childhood than any other factor IIRC.

This is not sour grapes - I'm a member of MENSA (which is really a boardgaming club); it's just historically accurate. IQ tests could be completely replaced with a tally of books read for pleasure (and the reading level of those texts), and you would end up with all of the same correlations without all of the self-important mathy-sciency tone.

I accept that there's a difference in the amount of knowledge that people have accumulated, and the amount of familiarity about how to evaluate common classes of questions that a voracious reader will have seen a million times before, and that a lack of those things may create a lot of challenges in college. I have no issue with the SAT. My issue is with the completely unjustified leap to a belief of differences in capacity, and the projection of this onto reified folk theoretical (theory-theory) internal states. This mythology is just another cultural construct to separate humans into "us" and "the others" and to alleviate the cognitive dissonance between our proclaimed ethics and open prejudice. Being a measure of the status quo, primarily, it serves solely to perpetuate it, offering no other benefit.

edit: early intelligence tests actually had questions that assumed you knew details about current baseball teams.

edit2: I also noticed that, other than reading for pleasure, the other examples that you listed for high correlation with IQ are degrees of adherence to cultural norms. Are high IQ people simply better at obedience?

CSS variables do something fundamentally different than SASS/LESS approaches. Moreover, it is something which those approaches are incapable of doing. Conversely, SASS and LESS do something that CSS can never do - be processed only once.

Much of the confusion I think is in the fact that we are referring to two dramatically different things by the same word "variables". In CSS terms it is more helpful (IMO) to think of them more like "user defined properties" which work exactly like every other property in CSS.

>This stuff could win on cost alone

For whom? Certainly not for me, I'm quite willing to pay a cost premium for real meat.

For poor third-world villagers, then? I have my doubts. I mean, so many cultures in the world attach so much cultural significance to eating meat, and the less often you get to eat it the more significant it is.

As far as point-missing innovations go, this reminds me of the Fleshlight more than anything else. You'd think that "feels just like a real vagina, only much cheaper and less trouble" would be a selling point, but it turns out that they're significantly less popular than the real thing.

Oh, I'm sure they'll sell some of this stuff, there's a whole freezerful of gross-looking fake-meat products at my local supermarket. But it's not going to change the habits of any genuine omnivores.
How would you argue that? Genuinely curious.
Fight for your right to hack
Using .apply({}, arguments) is actually a bit slower, but either method is so fast that it won't be a bottleneck. I use it in this case for elegance, because I can. Note that in your original implementation this is impossible, because you have to access the "type" variable and use one of two methods (sendUTF or sendBytes). `ws` has only one method (send) and the parameters of this method match the arguments to the callback for on('message').
You keep using this word, "meaning". What does it mean? ;)

The evidence that shows that saturated fat is bad for you is based on large-scale population surveys that only demonstrate that most Americans who eat lots of saturated fat are unhealthy. They don't demonstrate a causal link between saturated fat and heart disease.

On the other hand, there are plentiful clinical experimental studies which show health benefits from switching to a diet heavier in saturated fats, including favorable changes in cholesterol levels and body composition. Peruse these articles when you get a chance:

http://www.nmsociety.org/low-carb-research.html

In particular, it's important to note that Americans have decreased their saturated fat intake since the government told them to in the 70s, and heart disease rates have gone up:

Not to sound contrarian, but the 'something' you can do about that is to not ask for their first and last names.

I'm not suggesting that's the right or wrong approach, but you should ask yourself the following questions every time you ask the user to do anything, especially so when asking for their personal information:

- Do I really need this? Does the app break if I don't get it? Does the quality of the app diminish? Is there some measurable way in which this impacts me negatively?

- Can I rely on this? Can it be verified? If a user enters his name as "Pinocchio Dandelion", can I say that it isn't? At this point, if it IS incorrect, refer back to question #1.

By my estimation, generally, if you're asking for names, and it matters, you should probably also be asking for credit card information, or some other way to vet that data. If you aren't expecting to bill them, you probably don't need to ask for it.

Of course, you might have something in the app that does need it that we can't see from the outside, but most commonly in these scenarios is that people think they need the information and really don't, which means that you might have captured an even larger percentage of users in the signup funnel.

In regards to signups, you really really really want to make it as frictionless as possible. Once you have their email address, you almost certainly have a more 'committed' user than someone who hasn't filled out the form at all. If first and last names are nice for you to have (but not strictly necessary), then you can ask for them later, after you have their email address.

Once you have the email address though, that gives you the ability to try and lure them in further. Patio11 (as usual) has more detailed information on this topic, so I'll refer you to his posts as to why having an email address is a really good thing, but suffice it to say, it is.

It's really very simple. I'm not doing anything "wrong," but I cannot guarantee that my definition of "wrong" is the same as the government's.

Recently I've come across an argument that I think helps reveal the problems to those who are not prone to see them: if you have nothing to hide, would you give a copy of your house key to the police to check on your house whenever they want?

Suddenly everything becomes obvious: the cost of inconvenience (what if I'm asleep?), the cost of potential corruption or incompetence (what if they lose the key?), the cost of potential misinterpretation, etc...
I hope we've come at least a bit further since the renaissance.

I may not understand your definition of 'further'.

People are no smarter than they they were in 1500. There are no new cultural institutions.

Our toys are better, but people is still people.
I agree. This is a legal issue about 1) patent law, 2) Apple store policies. Whether your kid really needs the app or not is pretty irrelevant. I don't mean to sound heartless, but I think the emotional outpouring weakens the case for what you're hoping to achieve. The way it reads to me is "SfY is probably in the wrong here so I'm not going to defend them, but please just let everyone keep using this infringing software."

My whole take is that a patent for a device that plays a sound when you push a button with a picture on it is a complete joke. Surely there is prior art.
The bigger problem with "nothing to hide" is that it implies that what currently qualifies as right or wrong will hold in the future.

And while people in the US like to take for granted that democracy inevitably marches towards freedom, that simply isn't always so.

There's no guarantee that what was once illegal or suitable grounds for harassment by the community and authorities won't become so again.

"Harmless" records of yourself enjoying alcohol, common recreational drugs, listening to certain brands of music, interacting with currently-legitimate political parties or activist groups -- all could one day be held against you and be found as grounds to have authorities and/or the wider community harass, arrest or otherwise sanction you.

I'd much prefer to find ways to use that $50K that contribute to the economies that my industry supports and relies upon.

I'd rather burn $50K paying on-staff marketing or agencies to work around a sub-optimal domain name. I'd rather buy my staff new MBPs (or I would have before this soldered-in RAM bull). Hell, I'd rather support my local liquor store and buy a few cases of Great Divide and several dozen wings every Friday and invite everyone over for a free gutbombing.

Bottom line, I'm not willing to use my funds to perpetuate a business model that relies on a flavor of extortion.
As a matter of fact, it already sometimes does. For example, Texas Pete canned chili sauce contains soy grits instead of meat, yet makes no attempt on its packaging to advertise that it is vegetarian.

I also wouldn't be surprised, given the incredibly low cost of textured gluten, if there were a fair number of Chinese restaurants out there passing it off as "duck" in their dishes.

So far, vegetarian meat substitutes have been treated as a niche luxury good and made very expensive for western markets, but this is an artificial effect caused by demographics on the demand side, not a matter of supply costs. You can see proof of this by shopping for fake meat at Asian markets and comparing the prices to those in the hippie section of their local supermarket. A bag of dried soy protein that will turn into the equivalent of several pounds of ground beef can easily be found for under $3.

Depends what the real meat premium gets to.

Would a real meat eater rather eat a $5 burger made from (well you really don't want to know what burger meat is made from) or a $5 fake-steak sandwich that looks and tastes like steak?

The initial market is going be fashionable fake meat for Wholefoods/Trader-Joes consumers. But assuming this is eventually cheaper than meat, keeps longer, has less problems with bugs/contamination/spoilage, is quicker easier to shape into burgers plus lower fat and healthier then fast food chains are going to offer it.
