Sure, that's a pretty good idea.

Figure it out. If you want a cookbook solution, the answer is probably to just play the GPA game.
I like your plan, but I think you need a steady subscription cost. This subscription has the two fold advantage of giving the space a predictable income, and it makes the spaces participants less likely to engage in "not my problem" usage of the space itself, ala tragedy of the commons.

A hybrid system like what zipcar uses might work well. A small yearly membership rate (roughly £50/year) + reduced £15/day usage rate. Best of both worlds.
>> Wait, why on earth should people be prevented from leaving a negative review when they have a negative experience?*

They shouldn't be. But now Yelp controls both the reviews and part of the experience. It's a conflict of interest on multiple levels. It was already an issue when they started filtering reviews and letting paid accounts have more control. Now they also have a hand in ordering/processing/delivery.

The only analogy I can think of is Amazon–which has both reviews and its own products (Kindle). A bad review of the Kindle hurts Amazon directly. Therefore, it incentivises them even more to make a good product.

Yelp, on the other hand, never suffers from a bad restaurant review, a charge error, or a late delivery by one of it's partners. Only the restaurant suffers. In fact, a bad review is good for Yelp because it becomes a sales lead.
too! Seriously, it's not that hard.

When you think of upfront pricing it just makes sense. Recently someone posted a breakdown of their surgery here on HN (don't remember the kind of surgery it was, but it totalled about $30k), I don't understand how a hospital with the same medically trained staff as any other hospital (with exception of specialists of course which would vary) can be 4 times the price as this hospital is offerng to do it for and most likely the same level of care. I encourage everyone to read this Harvard Business Review article here which gives some insight into just how the American healtrh system runs: http://hbr.org/web/extras/insight-center/health-care/why-inn...
Exactly. One of my accidents was when a taxi driver honked at me, tried to overtake and hit the front of my bike and pulled in my front tire when trying to aggressively merge back into the lane I was in. Completely destroyed the front end of my bike. I was able to jump off the bike away from the vehicle to avoid getting hurt.
Mishka's Coffee in Davis, CA has an interesting approach to this. They have a small dedicated section at the front of the cafe that is reserved for [1] "the original, intended way [of using a cafe]". You're only allowed to read a newspaper or hang out and chat in this section.

"First come first served seems fair to me."

There are multiple definitions of fairness. FCFS might be considered a fair admittance rule, but not an occupancy rule. Consider processes in a computer system. Do we let one process hog the CPU indefinitely while others are waiting? No, most usable systems will context-switch when the current process exceeds its time quantum. "First in, first out" is usually a better rule for occupancy. Applied to coffee-shop seats, that would mean that people who haven't bought anything for a long time should lose their place to people who purchased something more recently. It's only fair.
Actually exactly opposite happen on game developers.

Is startup validation bullshit?
It's obvious from her words in the article. She wanted to bring people on board and the "old timers" didn't agree with her choices. Since the old timers are the epitome of a company's culture, then that means she was poisoning it. The options were to let her do it or let her go.

I agree that demand pricing has a valuable role in our economy. On the other hand, notable kindness and lack thereof can easily have significant reputation and PR effects, both positive and negative. The "Don't Be An Asshole Rule" does not seem to be about preventing demand pricing in general, but instead about the PR value and cost of such actions in the wake of a disaster. Clearly Hailo is reaping a PR payout for leveraging its infrastructure to assist Toronto residents.

The point is that Uber does not appear to have included the PR cost of surge pricing in their calculus, and subsequently tried to deny that it happened in order to recoup some of the PR losses. Perhaps they should have included an earlier human intervention option.

Comments regarding the risks drivers bear going out in a storm also merit some attention. Possible responses that come to mind easily:

* Cut the margin the company takes off the fee
* Allow drivers to enable some form of hazard rate when things get dicey
* Providing additional advice and hotlines and such things has nothing at all to do with rates, and gets PR points, if Hailo's experience is any indication

I'm sure the rest of y'all can come up with more suggestions. The point is that demand pricing is not evil, but PR costs matter.

Yep, but the sunbelt migration coincided with A/C proliferation.
College classes vary widely too in the US. I took classes where 100% was basically the expected grade, and I took classes where I got a 40%, which was among the highest grades in the course.

I think this variance is fine, depending on the course. It is reasonable for a foreign language course to expect a 100% on an exam, if they are testing and teaching to some particular guideline, for instance. It is also reasonable to push the limits in something like a physics course, to test both "can you regurgitate", "did you understand", and "no, really, did you really really understand"?
I look at it and think some web designer really thinks the network logo staying on during an entire television show was a great idea. I just hope they don't start having animated ads drop down from the bar every couple of minutes.

I don't have much experience with haskell beyond Learn You A Haskell (a book), but I wonder how beneficial the no null pointer errors are in practice.

The way haskell handles this reminds me of checked exceptions in Java. In java if you read from a file, your code won't compile unless you have a catch block that handles the possibility of an IO exception. This is called a checked exception because you have to check for the possibility or else your code won't compile.

I know many Java programmers handle checked exceptions by wrapping the checked exception in a unchecked exception so they don't have to deal with it. Don't Haskell developers end up doing the same thing with their Maybe concept?

Haskell avoids null by using a Maybe type/class (I always forget the terminology). A Maybe can evaluate to either a value or a type that represents the absence of a value. (This is an oversimplification for the consideration of people who know nothing about Haskell)

For example, you've got an associative map data type and you find an element in there. At the time of writing the code you "knew" that the element "has to be there". Haskell makes you deal with the possibility that it's not. Won't most developers just end up throwing an exception in that case so they don't have to deal with the impossible possibility? Then, x months from now when the code gets changed so that the map won't have the element there, all the sudden your code gets an error. How is this different from a null pointer exception in any other language?

(Part of me is ignorant and part of me is playing the devil's advocate.)
I think it is entirely possible to use a curve, or even a scale to adjust a percentage score to a numerical grade. You can establish a minimum acceptable proficiency... say 55%, less than that, you fail. over that, you can have a curve that adjusts against each student and other students in that class (or even prior classes) on the same level/exam for a final grade... accepting 10% will get a D, and 10% will get an A, with the rest spread evenly with a B and C.
I honestly have no problem with this.
If a shop feels the need to enforce limits then that's fine and is up to them.

If I go to a shop and there are frequently no seats for whatever reason I will stop going there. If I need wifi for something and a shop doesn't offer it then I won't go there either. It's up to the coffee shop to decides how best to balance this for themselves. There are plenty of other coffee shops and I will go to the one that normally has space and has wifi and good coffee if at all possible.

If I'm ever at a coffee shop too long then a worker there can ask me to leave. I will happily pay my bill and leave. However I will likely never return to that coffee shop. This is up to the shop, if they need the seat more than my custom then I honestly have nothing against them and as I said, there are many more shops. (I have never actually been asked to leave a coffee shop however.)

> However, they are (presumably) creating a body of case law. And case law is law.

Are they? Non-appellate court decisions, except in that they are binding in future disputes between the same parties under the principle or res judicata, aren't binding on future courts (not different courts, nor even the same court.) Appellate court decisions are binding on lower courts subject that court of appeals, but its not clear to me that, even with the review relationship they have, that the relationship between the FISC and the FISCR is one of lower court and appellate court such that the decisions of the latter are precedent binding on the latter. And even if it was, IIRC, only published decisions generally serve as binding precedent.

So I'd be inclined to say that the FISC almost certainly doesn't, and the FISCR probably also doesn't, really create case law in any substantive sense.
They are being recorded in a public space. AFAIK there are no privacy violations involved in recording them on public roads.
> If math & science is so hard, the real question should be: why the hell is everything else so 'easy'?

Look at usage.

I majored in CS, minored in Mathematics, yet as a programmer, I do more communicating in English than anything resembling math, and about an even amount communicating ideas and coding.

Growing up, everyday we speak, talk, write. We live history all around us, we see TV specials about WW2, parents and grandparents tell stories about their childhoods.

When is math truly used? On occasion, sure, it serves its purpose quite well. But in day to day life? One does not go around taking the derivative of arbitrary objects, but one may very well be called upon to present a persuasive argument or find a moment to whisper poetry in a loved one's ear.

It may very well be a case that our daily living does more to reinforce materials learned aside from the math and sciences.
When I compare the coverage of this with the endless coverage of the safe landing of the US Airways plane in the Hudson in 2009, this coverage does not seem sensationalized or over the top. In fact, this strikes me as some of the least sensationalized coverage of a fatal plane accident that I can recall.
That was sort of a trap. It's considered bad practice in academia to bypass the committees and speak with the professors directly. Professors usually say in their home pages something to the effect of 'if you want to do research with me, apply to the school, do not contact me directly, I will ignore you'.
I'm gay. Was making a joke at "fruit fly". Will save the one-liners for Reddit and Facebook posts.
The thing with these types of people (realtors, restaurant mangers, etc.) is that you can make something extremely easy to use but there will always be effort in producing new content; effort they are not willing to expend. Time and time again I've worked with people who couldn't be bothered to enter the data for their new listing or upload photos. They always feel like it is busy work and better farmed out to an assistant or done by myself at a unsustainable cost. Maybe the problem is that most of these people are technically inept and/or can't type more than 10wpm, I don't know. I've completely given up on anything real estate related and refuse to take any projects in that space because the failure to produce new content and maintain a web property always gets reflected back on me, as if I made something too hard for them to do. Plenty of dead-simple options exist to create and maintain a site, I find the issue is lack of cooperation with the site's owner to produce new content.

Now in the food service space, you could easily auto-generate an update based on the POS inventory. The problem there is many restaurants use a system like Micros, which has data access, but refuses to open it up to third-party vendors. If Micros ever wised up and opened an app store where customers could install approved and signed apps, the person who bridges inventory to web will cash in and retire early.
What if you have video to prove it? I wish it were possible to send such videos to the insurer of any vehicle. I know that with taxis, you can call up the dispatch company to get the insurance company of a vehicle, but I don't know if there is a way to find the insurance company of a private vehicle.

Showing this kind of behavior could prompt their insurance to drop them or possibly increase their premium.
I don't use homebrew, but your comment made me realize what I needed to do to successfully compile git with pcre. As a result, this now works:

git grep -P "outer\b"

Yay! Thank you and moonboots.

This is an important feature for me, because I organize my code lexically (primarily by being disciplined about using unique names for things) and rely on grep to quickly find what I want. Occasionally one unique name overlaps with another, and then I really want to match the word boundary.
I'm not considering automobiles as inherently more "valid" participants of traffic than bicycles. I just consider any road where two types of vehicles of very different sizes which behave very differently to be an inherently unsafe and inefficient road for all participants. Obviously, the occupants of the larger vehicles are much safer in collisions with the smaller vehicles, but that's not my primary consideration. I just think the roads, or at the very least the lanes, should be dedicated to only bikes or only automobiles. Since there are far more automobiles than bicycles on most roads, if building new infrastructure is out of the question, I think it makes sense to not allow bikes to share the lanes. This isn't a condemnation of bicycle commuting, but rather a basic appeal to safety and organization, just like pedestrians are not allowed to share lanes with automobiles. The current situation on most roads, where a small number of small slow-moving bikes occupy lanes in the middle of a sea of automobiles, is just a disaster waiting to happen (and in big cities, it happens all the time).
That Time article leads with a mischaracterization of the debate. I haven't read Outliers, but I did read a bit of K. Anders Ericsson's original work. Ericsson qualified the 10,000 hours saying that it had to be a certain type of deliberative practice, and that there was a limit of about 4 hours per day which could be spent on it.

In other words, it has never been the case that 10,000 hours is all that's needed, only that that is a minimum number.

However, you reject here Ericsson's entire thesis, that being summarized in the Time article as "Ericsson doesn’t deny that genetic limitations, such as those on height and body size, can constrain expert performance in areas like athletics — and his research has shown this. However, he believes there is no good evidence so far that proves that genetic factors related to intelligence or other brain attributes matter when it comes to less physically driven pursuits."

You made a claim that "innate talent or intellectual capacity" is essential to being an expert. This is a widely held belief, first articulated (I'm told) in Vasari's "The Lives of the Artist" (1568). The debate is - where is the evidence which justifies this widely held belief?

You see a danger in promoting this "meritocracy" ideal. I have two objections to that. First, I think you are using the term incorrectly. Suppose we only have innate talents as part of our genetic nature. Under a meritocracy, those who are naturally smarter, etc. will get a better job or higher position than those who aren't. It doesn't make a difference if it was achieved through deliberative practice or innate nature. Instead, I think the better word is 'egalitarianism.'

Second, it reminds me too much of various view of "noble blood" and rusty arguments that women by nature can't do X, that black people by nature can't do Y, and that Swedes are by nature dumb squareheads. There's any number of these stereotypes once fervently held to be true, but which haven't stood up to the test of time.

Also, there shouldn't be a good argument that "people just need to try harder." Ericsson's view is that "deliberate practice requires effort and does not lead to immediate reward" (quoting from a summary by David Zach Hambrick). There are many good reasons to not become an expert on a topic, including: 1) the person could be interested in becoming an expert in another topic, 2) it can be hard to find the 10,000 hours needed for practice, especially if that time is spent making money needed for rent and food, and 3) other requirements may be missing; it's hard to be an expert surfer if one lives in Colorado, or downhill skier in Miami.

The path towards being an expert in anything is chaotic. I am one of the world experts in writing software for a certain subset of biochemistry. But had I gotten a different job just out of college, I would probably be in a completely different field. It's really hard for me to believe that I was born with this talent, given how much education and job-related experience I had through to get to this point.
Yes, Its up to the airlines. 500ft to be stablized is relatively safe. 1000ft is a little safer margin, but not having a stabilized visual approach procedure is definitively risky at best, and sometimes fatal.

http://en.wikipedia.org/wiki/Southwest_Airlines_Flight_1455 is an example of an experienced crew making unstable approach and landed high, then overran the runway and crashed. 500 ft for Southwest pilots to be "in the slot" or go around.
This is the syntax I use in Emacs, so I would love it if git-grep would do the same. But it doesn't, for me. Are you sure that it does for you?
As a teacher, I take strong issue with dvt's comment: "We'd get some material that was non-trivial to figure out on an exam. That's just bad teaching."

Exams are supposed to be non-trivial, if they are to test your understanding of the material. When I teach freshman calculus, I invariably get this kind of comments from students who aced math in high school because they had basically memorized all possible question patterns from the textbook. But did they understand it? More often than not, they hadn't, really. And when they get a question that doesn't fit a pattern they've seen before, they call it a "trick", when it's anything but.

I work hard at getting my students to understand that math is not about memorizing stuff but about understanding stuff. You have to know the basic concepts and techniques by heart, of course, same as any subject, but anything more is just icing (unless your brain works in such a way that memorizing patterns helps you understand general principles, in which case memorize away, but don't mistake the means for the end.

Many students tell me they don't understand why they got a failing mark on an exam because they did all the homework and/or put in tens of hours of study. They seem to think that these actions should somehow guarantee them a passing grade, and if it didn't, it's obviously because the exam was unfair.

Now let me be perfectly clear: I don't give hard exams. In fact, most of the questions I ask are downright easy, provided you understand the material. Here's an example: "Sketch the graph of a twice-differentiable function f(x) whose domain is the real numbers and which satisfies the following two conditions: f'(x) is negative for all x, and f''(x) always has the same sign as x." This was in fact a question in my calc 1 midterm last year.

Out of 60 students, 10 did not write anything. 10 drew something that was not the graph of a function. 10 drew a function that did not satisfy any of the requirements. 10 drew a decreasing function but got the concavity wrong somehow. 20 gave a correct answer. (This is all approximate, of course.) The average mark for this question was probably around 2/5.

Was this exam question harder than my homework problem sets? Absolutely not! It's just different. Here's an example of a homework question relating to the same material in a similar way: "A differentiable function f(x) is such that f'(x) never changes sign. What can be said about the number of zeros of f?" This is more difficult than the exam question because the step linking the sign of f' to the number of zeros of f (drawing a graph) is not explicitly suggested, and because the answer is "f has at most one zero" and not "f has exactly one zero".
It would be really neat if you could tap a number and drag it left or or right to adjust it's value. Everything would recalculate and you could have a small dialog box out to the side to adjust the increment level of the 'drag adjustment'. An iPhone screen probably wouldn't have room for the dialog box so you could putting it in settings but for iPad it would fit just fine.
And #1 definitely isn't always true in my experience. I'd guess that smaller companies are less likely to care about grades.

GPA is maybe a useful indicator of work ethic, but there are so many factors it's hard to be sure of that.
This is Rotterdam at the end of World War II:
http://upload.wikimedia.org/wikipedia/commons/thumb/1/19/Rot...

Modern Rotterdam was built almost entirely after World War II, the same era that many American Sunbelt cities were built to their current size. In Rotterdam, the mode share is: 5% pedestrian, 14% cycling, 25% transit, 56% automobile. This is very auto-oriented for the Netherlands, but still more than twice the 6% bike mode share of Portland, Oregon, a mid-sized American city famous here for loving bikes.

That illustrates quite well that America's near-exclusive automobile use in many cities is a matter of city planning and development policies in this country (wide, high-speed roads optimized for moving the maximum number of cars, minimum parking requirements, minimum lot size requirements and setbacks, strict zoning laws separating residential from commercial uses and single-family homes from apartments) mandating a suburban form that makes non-automobile transportation difficult or impossible. It's not simply a question of the age of a city.
Base load. Please look this up when talking about using renewable energy sources for our electricity. Without things like nuclear power, coal, and natural gas plants we cannot maintain a proper base load.

This is totally besides the fact that when you look at the break down of the environmental impact of all power sources, nuclear continues to be one of the greenest solutions.
