I'd love to see a repository of problems from the back of textbooks. I think there's some law in education that says that you can copy <10% of a book and legally distribute it.
Looking at the replies to my previous post, I'm guessing my choice of words had connotations for some readers that I didn't intend. My point was merely that a lot of the people arguing for high tax rates for above average earners today seem to be doing so in the belief that they will be collecting more money from the super-rich, whom they regard for whatever reason as being legitimate targets. However, the reality is that it's usually not the bankers with million pound/dollar bonuses or the pop stars flying to their concert on a private jet who are ever going to be paying those rates, because they all have sufficient mobility to escape the high tax rates by moving their assets and/or themselves elsewhere. So, I think it's more likely to be those who are significantly wealthier than average but not super-rich who get hit by these rates, and many of those people are self-made and the lucky ones.

For example, while I'm not an expert on French taxation, I know that in the UK right now there is considerable debate about a 40% marginal tax rate for those earning above the higher rate threshold, because that threshold has been steadily reduced in real terms to the point where unlike the situation when that rate was first introduced, today quite a few people working full time in ordinary professional jobs would get caught in that bracket. (For context, with the latest tax bands and income levels, well over 4M taxpayers will be caught in that bracket, from a total population approaching 64M.)

Then there's a marginal 60% rate for a while when you hit £100k, which is certainly a very nice salary to be earning, but at a little over three times the national average it's hardly super-rich. It does cover the senior positions in some professional and executive management roles, but it also catches the entrepreneur who takes a couple of years of very low salary (forfeiting their ability to take more salary at lower marginal tax rates, of course) and then makes good on their business and is able to draw a larger salary the next year.

If you're interested in what people in different relatively well-paid professions really earn, you might find this helpful; it looks like being a doctor or a pilot is a promising option if you don't fancy the management path:

http://www.theguardian.com/money/2013/dec/18/what-are-the-be...

In short, I believe a lot of people don't think much of the super-rich, and they would be happy to see them get dinged for more tax. Sometimes there is some objective justification for this, but if anyone reading this thinks there's really no envy involved, I've got a nice second hand car to sell them. In any case, a lot of the people keen on the higher tax rates probably don't realise who is really going to wind up paying them, and how little effect they really have on the super-rich.

Java can do it without too much trouble, you just have a version number on the collection that gets incremented with every mutation, and the iterator just checks to see if that has changed. C++ is much more complicated, allowing patterns like map.erase(i++) being legal but similar usages not.
In Sweden there's a popular food delivery service that simply ties together restaurants and taxi drivers. This eliminates the need for round trips, since the taxi driver can just find some other fare for the return.

This works fine in Sweden which has a deregulated taxi market (=no shortage of available taxi drivers), but it wouldn't work in SF which has such an artificially constrained supply.
Animating the Metropolis Algorithm
Likewise. The professor/lecturer taught the material in the class, with spoken word and blackboard scrawlings, with some paper handouts for the occasional supplement and for question papers. Recommended books were for those who wanted to go deeper in a particular area and were available for loan in the library and were very much indicated as so; you could pass every exam with no more than notes taken in class.

The idea that a book would be necessary for a class that a teacher should be teaching seems crazy.

How would allowing defaults on government guaranteed student loans lower the cost of college? Cost would likely increase for most students.

If loan interest rates were increased to compensate for the additional losses this would increase the cost for everyone getting a college loan who doesn't default. And since default has significant costs overall costs would also go up. Lastly this would reduce the incentive to make wise decisions on educational choices.

On the other hand if interests rate remained the same then this be an would increase government subsidies and thus demand and thus costs for everyone. And again would reduce the incentives to make sound financial choices on education spending.

Either way costs would very likely increase for most students and we would get a less efficient education system.
This is my biggest concern since I'm currently a third year at university. It's only by luck that that I'm in a field that pays above minimum wage and it currently in demand for interns.

For others retrospect: I got an 8 month internship after my second year and saved up enough money to pay for my next semester and some savings. Following that semester, I took another 8 month internship with the same process. I'm now finishing my third year (so to speak) and I intend to get another 4 month internship so I can use my remaining savings for a last full year of tuition and spending.

I can't encourage enough that more people should look for and apply for internships for this reason alone if no other.

I hate the idea of being in debt and this seems like the only way to survive.

The overall tone of contempt is what I got "this is dumb" from.

If this is just a very, very slight twist on a business that has existed for decades you might ask yourself why it's only happening now. It could be that it's not workable. It could be that nobody ever thought of it. Or it could be that you're missing something, that you have also confused "I see nothing here" with "there is nothing here".

Embedded manufacturers have to deal with parts going out of production all the time. Say that Chinese LCD display you were using has suddenly gone end-of-life and hey, here's a replacement that fits our housing exactly but - oops- it looks like the driver needs a slightly different timing spec and color layout.

The WinXP users are in the same boat as the Ubuntu users - someone is going to need to update that video driver and smooth that new software into the production run without tanking machines that are already out there. Service techs HATE having to deal with 24 different flavors of the same circuit board and crossing their fingers they updated the right file onto the correct board.

So yeah it's lazy that relying on Windows to handle all that lifting but, hey guess what, there's a lot better chance someone has a Windows driver for that new display that the Ubuntu crowd does.

Android has a lot of potential for embedded GUI usage (I'm doing it myself) but the driver stack integration is a LOT tighter than slapping another DLL into the mix.

Why do you need to work your way through college? Get a loan, Take more credit-hours per term, and pick a field that will give you a greater pay increase and your work will be worth a lot more (per hour) when you graduate. I understand this is an oversimplification because some people can't get loans/grants.

You are right of course but there is also the possibility of loss leaders. And many times in business things don't make sense on the surface but play out differently. Perhaps they will have add on items that will generate more profit. Perhaps the amount of people who only order bread alone will be small.

If they get funding they have the staying power to test the market and potentially find profitability. That's the big big advantage of using "OPM" when starting a business. Not guaranteed but not a non starter either.

One big benefit of starting at a low price below costs (if you can) is that it keeps others out who think "we can't make money doing this".
Maybe I'm being selective about my memory, but I don't remember the awful linkbait titles being nearly so popular in 2007 when this was written. I don't think there's even the hint of imitation of Buzzfeed-style titling here. Also, I've taken a class from one of the authors, and I'd be surprised if he'd ever even seen those kinds of pages. :)
i'll admit that that's a convincing argument, but there are ways in which apparent causality can be shown to be illusory. one thought experiment i remember from school involves someone watching a movie in which one character punches another character, and the punched character falls backward. suppose the watcher knows absolutely nothing about how movies are recorded, or re-played, and sees only the lifelike images; then there would be clear, apparent causality of the second character falling over as an effect of being punched by the first. in reality, the only causality is that set up by the mechanics of the movie projector.
The author being right 2 different ways doesn't make it less right.

Any moderately busy pizzeria will queue up a few delivery orders that end up being ready at around the same time, and will have one driver deliver them all within a single trip.

The trip may take marginally longer than if just one order were being delivered, but it ends up fulfilling five or six orders with one trip. The cost per order ends up being decreased to a reasonable level.
Supply at the top end is fixed. More and more people want to go to Harvard or Stanford, but it's not as though the supply of super-elite colleges has expanded.

What seems to have expanded most is a means of getting a generic "college degree". Compared to that time, there are a lot more low-end places which will accept people with a checkbook (or federal student loan) and a pulse.

Also, you can even acquire the knowledge associated with a degree, but without an actual diploma (MOOCs, online learning, etc).

I mean, none of these are truly fair comparisons. There's no question that there are many things Sf will be better at because of its size and there's other things New York can offer because of its size. But that's what this whole thread is about, comparing the two cities regardless of the root causes for their differences. For example, sf has better quality food in general, since the weather is more forgiving and farms and wineries are quite close. Still, there's no question that the food in sf is of higher quality on average.
I care about this question. I think that 'creating algorithms that act as if at a human level of intelligence than creating algorithms that recreate human states of mind' is part of the problem, and acts as a limitation on our AI. I am actively interested in AI that has a sense of self and is capable of developing preferences rather than mere opinions.

That doesn't mean I buy Searle's argument, and indeed have refuted it below. But I do think that dismissing the questions asked by philosophy out of hand is a mistake, and is causing us to overlook opportunities. The most likely place for general AI to develop is on mobile devices - not in a her type human fashion, though.

Pielke's response is here:

http://rogerpielkejr.blogspot.com.au/2014/03/john-holdrens-e...

It was extraordinary that Holdren should write such a harsh attack on an individual scientist, particularly when as pointed out by Pielke that his response is entirely consistent with IPCC SREX.

Here is the most important quote in Pielke's article:

What the IPCC SREX (2012) says:
“There is medium confidence that since the 1950s some regions of the world have experienced a trend to more intense and longer droughts, in particular in southern Europe and West Africa, but in some regions droughts have become less frequent, less intense, or shorter, for example, in central North America and northwestern Australia.”
For the US the CCSP (2008)20 says: “droughts have, for the most part, become shorter, less frequent, and cover a smaller portion of the U. S. over the last century.”21

It appears that stating what the IPCC says is now outside the consensus according to Holdren.

> Hence a goal to have 50% of people have bachelor's degrees by 20xx

Interestingly, the college enrolment rate is 66% in the USA with around 30% of the population completing. Similarly, in Canada, the university enrolment rate is 50% with 25% of the population completing.

Given that, it seems that the only way we might even be able to come close to a 50% degree attainment rate, in North America at least, is to force everyone into college or make it so easy that anyone can do it. Neither solution is one I would feel comfortable getting behind just to meet artificial targets.

Can you shed some more light on how the Danes hope to be able to achieve this beyond the financial aspect? What makes their population more successful in academic pursuits?

- increasingly top-heavy administration (hey, let's add another $300K Assistant Deputy VP of Student Diversity, etc) providing a path for faculty to 'advance' in their careers

I'd like to point out that much of the administrative bloat has occurred because of new (bipartisan) laws forcing colleges to provide more services. There are services for veterans, services for the disabled, services for victims of crimes, oversight services for grants and such, etc. My girlfriend works for a university, and much of the administrative hiring they do is directly correlated to new requirements, laws, and administrative rules passed down from the federal or state governments.

So I think you're right, but don't place all the blame on the schools, just as much belongs to the political parties that like to use universities as a battlefield for whatever agenda they've got at the moment.

Edit: It is especially wrong to think that the faculty are driving administrative bloat when, in fact, the faculty are the biggest opponents (and literally stage rallies against it at some schools) because every dollar the university spends on an administrator is a dollar they don't spend paying a faculty member).

There was some mild backlash when gmail started automating ad delivery via email content but then people went crazy over the 1GB mailbox and forgot all about it.

The assert from assert.h is a macro that completely elides the check if built with NDEBUG. Assuming you're not using some other assert(), and are building your production build with NDEBUG (which is typically part of what's meant by "a production build", though you can certainly disagree with the practice), production code cannot capture it as no messages will be generated.

I don't know the correct queryset, the one you provide seems good. Don't compute in Python what you can do in the db. In the particular code I'm referring to, several queries were done against the db instead of one.

> 1000-line is ugly

yeah, kind of. But at least you don't use abbreviations. Or 2 spaces for indentation. Seems like valid pep8.

I don't say that there are no mistakes in the code, just skimmed over it.

The file is big because some of the functions are not views.

- get_submission_age: should be template tag cf. https://docs.djangoproject.com/en/dev/howto/custom-template-...

- get_submission_set: I wouldn't use such a function. For sure you are iterating two times over the list of submissions, one time in the view, one time in the template so it's a "2n" so O(n) complexity. It's ok but only one iteration over the list is required. But the django template language (DTL) makes it "hard" to do it... DTL was built around the idea that the template writer is stupid and probably also that nobody would read the code the template writer wrote before going into production.
