Industry Open-Sources Model For Infamous CDS 161

Posted by ScuttleMonkey from the further-down-the-transparency-highway dept.
GlobalEcho writes "Credit default swaps (CDS) are infamous for bringing down AIG and requiring a bailout of hundreds of billions of dollars. Because the market for these was so murky, the US government has insisted that Wall Street create a clearinghouse for these contracts. In a fresh twist, part of the deal is that the models used to price CDS have been standardized, and that the pricing code was made open source, under a somewhat BSD-like license. The source code (originally written by JPMorgan) provides the basic pricing routines, plus an Excel interface. To my knowledge this is the first significant migration of an investment bank product platform from its usual super-secret proprietary home to the rest of the world."

Submission + - World of Warcraft Gold Limit Reached, Its 2^31 (wowinsider.com) 1

Mitch writes: "From Wow Insider: Blizzard apparently users signed integers for their World of Warcraft gold values as some people have recently hit the limit of 2^31. "Apparently that amount is 214,748 gold, 36 silver, 48 copper. After you reach that lofty sum, you'll no longer be able to receive money from any source in the game. While some responses to the original posts claim that this exact limit had previously been theorized to exist, there have been no reports of anyone in the game actually achieving this amount via legal means.". I guess Blizzard didn't expect anyone to ever get close to that much gold in game."

Submission + - Is parallel programming just too hard?

Submitted by pcause
pcause writes: There has been a lot of talk recently about the need for programmers to shift paradigms and begin building more parallel applications and systems. The need to do this and the hardware and systems to support it have been around for a while, but we haven't seen a lot of progress. The article says that gaming systems have made progress, but MMOGs are typically years late and I'll bet part of the problem is trying to be more parallel/distributed.

Since this discussion has been going on for over a decade with little progress in terms of widespread change, one has to ask is parallel programming just too difficult for most programmers? Are the tools inadequate or perhaps is it that it is very difficult to think about parallel systems. Maybe it is a fundamental human limit. Will we really see progress in the next 10 years that matches the progress of the silicon?
