It does not tell you how to calculate the interchange, but it does explain what interchange is and describes the variables that go into the equation.

Interestingly relevant to BSD-style vs. GPL-style licensing:

> The vision of freedom that most of the big corporate interests had was the ability to make their platform sticky: to destroy interoperability so that (for example) Java software developed on Microsoft platforms could only run on Microsoft platforms. They wanted the freedom to capture developers. ... "Freedom" is a freakishly relative word. The freedom of the large software companies is directly at odds with the freedom of developers.

> The argument for evented concurrency assumes threads work. Async design isn't a reaction to MRI's crappy green threads.

Truly? To my understanding, event loops require inversion of control (and likely callbacks and broken exception handling). This is a large cost that requires a benefit to be worth it. I understand that benefit to be: you don't have to deal with threads (or bad implementations of such).

This blog post comes to mind: http://www.unlimitednovelty.com/2010/08/multithreaded-rails-...

Too bad they don't dogfood it (source: Default.aspx):

    <div class=mainholder>
    ...
    <div class=sidebar>
    ...
    <div class=maincontent>
    ...
    etc.
Also, the classic (header, 3-col, footer) layout is missing.

e.g.

    HEADER
    ------
    C|C |C
    C|C |C
    C|C |C
    C|C |C
    C|C |C
    ------
    FOOTER

> Big corporations tend to operate in their stock's best interest, and this can still cause serious problems for their shareholders.

Erm, what? This seems contradictory on its face. The shareholder's only interest in a company is its stock performance, be it stock price or dividend payments. What sort of tendencies are you thinking of, here?

> don't the US corn subsidies for ethanol actually make corn more expensive?

My understanding is that the subsidies are there to incentivize corn production. The video says that the subsidized cost of corn production is actually negative -- that you can go plant a corn field and will have made money before you sell a single ear.

Once the corn is produced, if there are additional subsidies for ethanol production from corn, then that may divert corn from food uses. It may increase the cost of HFCS production.

But the cost of corn production is still lower despite, or perhaps even because of, the ethanol subsidies.

> These are obviously mutually exclusive definitions!

Not at all. He is saying racism is a subset of tribalism, as is being an OS fanboy. Tribalism the the umbrella term.

> However, the other counter argument against HFT is that it actually doesn't really provide liquidity to the market, as evident by the June flash-crash.

As far as I can tell, this is the only argument presented against HFT.

> But HFT dealers stopped trading that day, triggering a lot of people's stop-market orders

Are there other factors involved in this outcome, or is this a canonical HFT failure?

> the researchers hypothesized that, given some premises about evolution, poor women would have more kids earlier.

Um, isn't this already well known? Did they not craft the hypothesis to fit their existing understanding?

> Then they went and tested it.

No comment.

The "trouble" is only when you want a single process to monopolize the entirety of CPU resources. In today's (and even yesterday's?) processing environment, there are often tens if not hundreds of processes running at once, and 5 or 15 of them may be "performance critical".

Are multicore architectures not able to distribute this sort of load?

Erm, so the trouble with meritocracy is that higher education is bad? And we don't want to subject underprivileged demographics to the intellectually conformist ... education conveyor belt?

That we want to keep underprivileged demographics at home so they can critique the elites from afar?

Clarity is severely lacking. It's hard not to file this one under Anti-intellectual tripe.

> the reuters/AP of ...

Unintentional irony? Both of those organizations' reputations have become quite tarnished. They are certainly not contemporary bastions of fair-handed transparency -- witness Reuters' photo manipulation and AP's quote-whoring.

> Option – Open Source the Product

> No, Not really an option at all. Who would work on it? Sure lots of people love to consume open source projects, but very few people contribute to them. And I have put a LOT of money into this product, I am not going to just give it away until I can at least break even. I have to put my kids through college, hopefully reclaim part of the money I have put into the company, etc. And lets face it donation type projects never, ever make money. Advertising on the site, etc are all pointless wastes of time.

Um, how is this not an option when terminating the project is? I'm not saying that he should open source anything, but this justification is silly, especially when compared to his previous explicit option of killing and burying the project.

> it totally failed to address the question of wealth received through means other than entrepreneurship

These people receive wealth. They do not necessarily generate it. Athletes and movie stars are certainly talented, but entertainment is a place to push excess wealth and not necessarily a source of it.

> it claims that the rich got that way by doing work other people don't want to do, by which logic the average garbage man should be rich since he is doing work no one wants to do either.

No, doing disdainful work is not sufficient for being wealthy. Nor is it necessary. He is saying that it is common, though.

> Fourth, it lumps short sellers in with various other parasites trying to feast on the wealthy. But if good entrepreneurs will always (always!) grow the value of their companies, why should they fear short sellers?

Hm, I missed this part in the essay. Most businessmen recognize the value of short sellers in the marketplace, even if it makes their job harder. It's kind of like competition in that way.

I don't understand this point:

> I don't remember the exact details of the buyback at TheStreet.com but we started buying the stock and it kept going down. We kept buying it. But we were losing money on each buyback because we were overpaying for our own stock as it kept going down.

It seems to me that if your stock is trading at under book value, then you would be underpaying if you are buying it. Especially if it keeps going down.

Isn't the idea that the stock is undervalued? Why not buy low now and even consider selling high at a later date?

Old story is old. The guy's name is Joe and gave his name to news reporters as 'Gray Powell'. Flagged.

Ah, it is nice to see the licensing issue is directly addressed -- http://wiki.github.com/behlendorf/zfs/faq

> The CDDL does not restrict modification and release of the ZFS source code which is publicly available as part of OpenSolaris. The ZFS code can be modified to build as a CDDL licensed kernel module which is not distributed as part of the Linux kernel. This makes a Native ZFS on Linux implementation possible if you are willing to download and build it yourself.

> the problem of having a too fast processor on your deployment platform

The sarcasm here is unwarranted, as is basically your entire paragraph. Why not just say: Python is slow ?
