Sal is right but I understand the critique... which I might clarify as the importance of understanding the larger concept that slope is a comparison of the rate of change of one variable to another in specific order.

To take the example of price of an iPod vs. more memory. The slope is inverse depending on which variable you choose to plot on which axis. If you just watched Sal's one video, you would not understand why that is... your only context is 'rise over run'. If given sample data points and asked for a slope, you might not be able to figure out which way to plot it based on the question.

To be fair to Sal though, this was just a single video subtitled "Figuring out the slope of a line" and so Sal may have covered the larger concept and its importance in a different video.

Who else when they get a tweet about some known person who makes silly tweets. Does she call the police to have a word with him, no she tweets come on in effect. I don't like her and she optimises all the worst in politicians. She even set up her own tweet riip off, so for her to lambast twitter is purely alteria motives.

That it offends our highly culture-specific ideas, like eating horse meat. Also, something about feminism.

Polygamy has been practiced all over the world for a long time and is of course also something which is often mentioned casually in the Bible, so there is really no argument other than that it is not traditional in our mainstream culture and we have corporately decided we don't like it.

Personally, I don't support same sex marriage, bug legally I see no real reason to ban it. However, I'd prefer the government who represents me, not endorse a practice I don't support.

My solution for years has been for the government to get out of the marriage business entirely. Marriage should be a purely religious ceremony, and we can establish something like a civil union contract law to handle issues like joint ownership of property, child custody, and inheritance.

That way anyone, gay, straight, or polygamist can get the legal benefits of marriage, and they can find a religious institution willing to conduct the religious ceremony.
Were bans on interracial marriage incorrect? Was slavery incorrect? I'm not saying bans on gay marriage are as bad as slavery, obviously, but rather that there are certain issues which over the course of history will become generally accepted social truth. That is, of course, the only sort of "correctness" that is possible on a social issue.

Marriage, in the legal sense, just a particular type of contract, long recognized because of how commonly people wanted to enter into a particular type of economic arrangement. It is non-sensical to think religious institutions should have any say in defining this type of contract, any more than they have a say in defining the contracts that pertain to, say, residential leases. Should religious institutions be able to use Biblical scripture to argue that implied in any residential lease is a warranty that the landlord will have running water, etc? Of course not, that is the exclusive domain of the secular courts. The marriage contract, being no different, should be treated no differently.

>how was I supposed to determine this before you came along to tell me?

You hear other people's opinions and you make up your mind. It's painfully obvious that there isn't an objective repository for this sort of thing; the whole notion of 'inalienable rights" is rather recent and fluffy to begin with.

>What if I think that marriage should be defined religiously by a religious institution rather than legally by the state?

Yet we live in a society where marriage is legally defined. It's fine to work against abolishing the institution of marriage, but if that's the case witholding that legal definition from an arbitrary segment of the population becomes a petty argument over semantics.
Okay, well, that's kind of the point. Why are you holding a device designed to fit the human hand a particular way in a different way to get around its design limitations while claiming it's superior to another device designed without those limitations? The PHP hammer springs to mind.

Ha. Never thought of that. But no, it's not a feature in the sense of something that was designed with this goal in mind. It's a way of not having to design and implement a whole url scheme, and instead being able to easily run arbitrary code in response to a link being clicked. This architecture, however, has the undesirable (expect apparently to you) side-effect of occasional "unknown or expired link"s.

I replaced the array/"surrounding" list with an unboxed vector, and removed the strictness annotations and it runs at ~0.85 on my machine, while the C code runs at around ~0.5.

The code is so incredibly close to your SML code (where you also spell out that you are using the Vector type). I am just blown away by how matter of fact you were in your statement.

Please either change your benchmark to use the same data type as all of the other examples, or stop using it as an example of Haskell's performance.
I remember when the iPod first came out and was truly random. People would notice that song X came up twice before having played song Y and conclude that the iPod wasn't truly random. There was a big thing on Slashdot about how the record labels were paying off Apple to weight certain songs more heavily in the shuffle for their own nefarious purposes.

Then again, my memory isn't what it used to be, so maybe the Slashdot crowd was right about that one and I just forgot.

P/E only carries meaning for stable companies that aren't growing. If a company is investing for the long term, then their P/E might look terrible but they may be laying a base for huge profits in the future. Of course they might also be throwing money into a hole in the ground, but looking at the P/E ratio isn't going to tell you which of those are going on.

NB. Amazon's razor thin profit margins are what would worry me if I had a pile of AMZN stock, not their P/E ratio.

>"I think this was a deliberate over valuation to allow them to dump shares immediately make a ton and let the stock drop."

A stock trade is a two way transaction. A holder of shares doesn't get to just "dump" stocks; someone has to be on the other end of the deal. For every seller there is a buyer. Why would they want the stock to drop, rather than have it go through the roof, allowing them to cash in at a higher price? That makes no sense.

Political advertising would also work.

I'm opposed to dragging the vitriolic "I refuse to work with you because you're a Publican/Democrat/conservative/liberal/bleeding-heart/homophobe' behavior into a wider arena of life. I'm friends with and work with Republicans, Democrats, Libertarians, etc. and that's a GOOD thing. I don't want a world where our political differences mean we can't function as a society. I can't get my haircut there--he's racist or sexist or homophobic. No, he's a normally-okay dude who cuts my hair well.

I don't know how to best express this. Jon Stewart kind of talked about it at the Rally for Sanity when he mentioned how we don't cut people off for having a McCain bumper sticker.

Step one is to realize that being homophobic doesn't make you "terrible people". Three hundred years ago pretty much everyone was racist, sexist, and homophobic, but were in general as decent people as we are today; they just had some terrible beliefs, and terrible behaviors that came along with those beliefs.

i'm familiar with tex.

you seem to be asking two things.

(1) - can browsers support an ecosystem that matches what is available to tex?

(2) - can tex be used to replace web pages?

the answer to (1) is yes. browsers can be "programmed" with javascript to modify layout, just as mathjax does. for example, you could write a java package that formats text for printing by adding page numbers etc. this requires someone to write the high level logic, but the underlying layout engine already exists. you would also need a package system - something like what is being developed (requirejs etc).

the quality of existing results is largely a function of market, maturity, and expectations. you're comparing books (largely paid with existing toolchains) against web pages (largely free, all this is pretty new). the layout engine itself is, as i have already said, pretty much equivalent.

(2) is a confused mess that you don't seem to have thought out properly. and given the tone of your other replies i sure ain't going to help you.

libertarians do believe that market pressure should be used instead of government coercion. You'll definitely find plenty of them who do support a boycott of chick-fil-a.

At the same time there are other libertarians who don't support a boycott because they believe that people are entitled to hold opinions that differ from their own.
In math, is not accurate to say the "definition" and the "calculation" are one in the same? Sometimes we require ambiguous non-math language to start understanding a concept but ultimately, once understanding has happened, the calculation and the definition are identical.
I wonder if it would make sense for companies looking for Linux talent to somehow target users of less 'user-friendly' distributions such as Gentoo or Arch. I don't know how well it would work, but I imagine that advertising on a project web page or, if allowed, making an announcement to a user's mailing list could be a way to find developers.
You would not use Riak solely to build the backend of a blog. Riak is not like Mongodb or Couch; it is not another monolothic database with a different data model.

Riak's basic advantage is the way it handles scaling. Unlike monolithic databases that scale horizontally using master/slave architectures, Riak is distributed on day-1; your starting configuration would be multiple servers. Riak has no master servers. As and when needed, you add new nodes to Riak clusters with a single command.

What this offers developers is essentially a locally-hosted version of S3 with performance and cost characteristics that admit to creating lots of small objects.

Riak has other features (mapreduce over collections of objects, indexing, full-text search), but fundamentally, you'd use Riak for the kind of application that could be reasonably built around S3-scale key-value.

In practice, I've found Postgres and Riak to be a pretty good 1-2 punch: metadata (anything I'd use to formulate queries) goes to Postgres, bulk data to Riak.

My application doesn't have a zillion users, nor does it store lots of "files"; what it does do is generate a lot of variable-sized historical data. Before Riak, I'd have to think hard about how I'd digest that data and what parts of the data I'd have to throw away. After Riak, I'm finding I can basically throw disk at the storage problem while continuing to get consistent performance characteristics.

The thing that makes bone marrow transplantation so expensive (about € 100.000 a pop in Germany, probably more expensive in the US) is that in the time between killing off the patient's own immunosystem and the donor immunosystem taking hold, the patient effectively has no immunosystem at all. This takes about 100 days right now, during which the patient has to be isolated in an environment almost entirely free of pathogens.

So if you want affordable bone marrow transplantation, you either need to find a way to cheaply isolate someone while giving them a very high level of medical care, find a way to grow a complete immunosystem in a few days, or find a new drug that'll effectively fight off every possible infection in a body with no protections of its own. Oh, and then of course you have to affordably stop the donor cells from attacking the host's body, too. Finding a cost-effective drug to cure AIDS looks a lot more likely to me than any of that happening in my lifetime.
>"32% Y/Y growth isn't rapid ?"

That means Google has been around twice as long as Facebook. You don't consider that a long time in the tech world?
This point is an interesting crux of disagreement about methods, not just nitpicky. Technically, slope is the rate of change of the tangent to a function, and the disagreement is about how to communicate that to students.

Approach 1, Mathalicious: "Unless you give students the right information from the first, even if it is a bit more abstract, they won't be prepared later on."

Approach 2, Kahn: "The best way to prepare students is to keep things simple. Later you can give them refinements about tangents and derivatives and such."

This is an interesting point, and I'd be pretty surprised if there isn't already a wealth of knowledge surrounding it in educational research. (Neither Kahn nor Ani appeals to such research in the articles.)
Would they buy terabytes of music? No, but few people of any income level would. However it should be remembered that once upon a time, college students were a major market for recorded music.

Twenty years ago when I went to college (ugh, that felt weird to type) every dorm room had stacks of CDs in it... maybe an average of a couple hundred dollars worth per head. That music-selling bonanza just doesn't exist today.

I don't really have a strong opinion one way or another about whether this is a good or bad thing.
As a child of the multimedia revolution, it was strongly ingrained in us that going to college was the only route to getting a job that wasn't flipping burgers. To even consider learning in non-traditional ways would make you the laughing stock of not only your peers, but the older generations too. I'm not sure learning through multi-media ever stood a chance.

I do feel that those times have changed dramatically. Now all we hear about is the college dropouts who went on make billion dollar companies. It has almost become cool to not go to school. I think the time is finally right for these non-traditional educational services and it just helps that the internet is now widely available to act as the conduit for it.

Agreed, we have a lot of things which are wasteful compared to spartan requirements. Definitely a sliding scale of luxury. So what are the real costs of meat eating? 10-50x more water for a meat diet, is that moral or practical superiority?
I don't understand. You can't pickle functions; when you pickle a function, you get a reference to the function, not the actual function code.

E.g., this doesn't work:

Dump.py:
def isEven(n):
return n % 2 == 0
import pickle
with open('pickled','w') as dumpfile:
pickle.dump(isEven, dumpfile)

Loader.py
import pickle
with open('pickled') as loadfile:
isEven = pickled.load(loadfile)

This throws

AttributeError: 'module' object has no attribute 'isEven'

What you can do is marshal the function's code:

import marshal
marshal.dump(isEven.func_code, file)
#Then to load
isEven = types.FunctionType(marshal.load(file), globals())

But you can also dump a lambda's code:

import marshal
marshal.dump((lambda n: n % 2 == 0).func_code, file)
#Loading is the same
isEven = types.FunctionType(marshal.load(file), globals())
isEven(4)

So frankly, I don't get the problem with lambdas.

Google's core business is advertising. Google likes to do stuff with the data that passes through its systems. Google has explicitly and pro-actively taken sides in fight against copyright violations instead of remaining a neutral party.

And they've been less than steadfast on Net Neutrality, which is a big red flag for a company that wants to be an ISP.

This is not about Google being "evil", but I do not want a company with that mindset and those interests to be my ISP. It's going to be very tough, if not impossible to separate those.

I know this is already common practice in the US, with many of the major (cable) ISP's being part of companies that having a direct stake in copyright exploitation, advertising etcetera.

So ask yourself: how's that working out for you so far? Would Google really be any better?
