Can we stop quoting the underlying notional size when comparing size to equity markets? If you know how a derivative works, it's well understood that quoting the notional to represent size just doesn't make sense.

To put it simpler, a terminated CDS contract does not mean there is a loss of wealth equal to its notional, whereas a stock price going to zero in the equities market literally means you just lost the complete amount you invested.

Not to sound offensive, but I've heard this comparison way to many times and it just doesn't add up in terms of prices - most swaps, for instance, have their fixed leg in the single digits in relation to their notional.

Anyone notice how the main video on that page is almost exclusively women using the app? Guess that's linking in to the idea others have quoted here about the attractiveness factor of the photos in question.

It's interesting to think about how underutilized some of that knowledge actually is in the broad scheme of things - for instance, how popular is reading the classics of literature, versus the latest novella of the day?

Changes in technology have a fundamental impact on the way humans interacting with the world (for better or worse), an interesting book called The Shallows [1] highlights some of these points. Is the technology we're utilizing moving us in a direction that is long-term beneficial or harmful? People can access information more easily, but at the expense of what - lack of focus? Problems with deep thought and long-term planning?

According to the page, it's neither a framework, nor a library - isn't that a bit counterintuitive? That makes it sounds as if it is beyond any of the existing styles of code reuse in software development, which is not the case.

I'm sure many would identify it as a library in the classical sense, since it is a bundle of code you include in your application and make calls to.

Like the UI of your product alot - I take it there isn't a way to get the frontend without hooking up to your backend (e.g. simple IMAP setup?)

What is your business model for it? Since it's free, are you parsing all the mail and providing data services to interested companies looking to mine information?

How can one say: And not a single one of these game is using that "Component Entity System".

That seems like an impossible statement without deep knowledge of the inner workings of the popular games you are referring to, which you certainly don't have access to.

Also, CES is a fairly longstanding design pattern for game development (at least 10+ years) - I refer you to this comment: http://news.ycombinator.com/item?id=4907998

If you were planning to write a high performance game using python, most likely you wouldn't be using the vanilla cpython interpreter, but instead using cython (http://cython.org/) to write extensions in essentially C for all your high performance code.

I think it's important to remember one of the core tenants of python is to first write in python, then optimize the bits where necessary in C by moving those calls into an extension - by using cython you get to move to C like speeds by just annotating your existing python code.

Also - I think a fairly more common approach to using python in game development is to write the core in C++, then call out to python for scriptability purposes (e.g. configuring characters/levels) - rarely would one write a full game in python unless extensions were heavily used, for the reasons quoted above.

"Bigness" matters because only a few of the large banks are primary dealers [1] - they directly play a role in US treasury auctions. All the other investment banks that aren't primary dealers only play a part in the secondary market. Part of this relationship is also the agreement that large banks are always making markets [2] and providing liquidity for highly-traded Fixed Income products - without someone to make the markets, no one would be able to trade. A large part of the global finance system is based on the ability to easily buy or sell these products, from the huge institutional clients like Fidelity, to the individual investor using their Schwab account (albeit even that is done through a much larger entity to access the market). The move towards computerization in the financial industry over the past 30 years has directly impacted the bottom line of these large banks (via smaller bid/ask spreads [3]), but has also directly lead to increased liquidity due to trading volume.

After becoming somewhat disappointed with silverlight running in a win VM on linux (constant crashes, no reporting, buggy video driver usage) and being pleasantly surprised by the ease of running netflix desktop (http://www.compholio.com/netflix-desktop/) - I would say this couldn't be any farther from the truth. It's at least one instance of wine that has brought a previous inaccessible web app to the linux mainstream.

That goes against many recommendations I've read about refactoring and writing cleaner code:

"Good code invariably has small methods and small objects. I get lots of resistance to this idea, especially from experienced developers, but no one thing I do to systems provides as much help as breaking it into more pieces."
