LINQ: Language Integrated Query
In the upcoming release of Microsoft's .NET version 3.0, code named ORCA, they have a
fewature called Language Integrated Query (LINQ). [Come to think of it, v3.0 is now out,
I've been rooted in C++, I'll have to get back to C@ and check it out]. The language
extension allows one to
write queries for anything with an iterator. Writing inline SQL queries comes immediately
to mind. I've also heard that there is something called
PLINQ (Parallel LINQ).
Here are a couple of references regarding the subject:
On an unrelated programming note, erlang is said to be a language for developing interacting distributed
applications. One interesting capability is Hot Code Replacement (replacing code and data
without stopping the system).

C++ STL (Standard Template Library)
Here is a nifty shortcut to make C++ do what you can do in C#:
public static void ForEach(this IEnumerable ienum, Action func)
{
foreach (var v in ienum)
func(v);
}

Trading Site of the Day -- IVolatility.com: Implied Volatility Data
I would say, based upon the sites I've seen so far, at least from a volatility point of
view, IVolatility.com is probably the
best for information regarding volatility and its uses. As far as I can tell, they
provide data only, no brokerage services. For trading purposes, ThinOrSwim can nicely
supply that requirement.
IVolatility provides various and sundry scanners, the best option choice for the day,
many different ways to analyze options and their combinations, as well as a knowledge base
for honing your skills for any type of market. They also have, what seems to be, a weekly
Trading Digest Blog, which comes out on each Monday, for helping to identify the type of
market, and the types of trades to do
in that market type.
Anyone can by naked calls in a rising market. The true traders ar those who can make the
right option combination in a rising market, a falling market, or a sideways market.
I wish I know about this site when I first learned about options.
