Approaching geekery in an ad hoc and improvisational manner. Binomial Option Pricing with Alchemy. Yet another version of the binomial option pricing algorithm (sorry), but this time I’m using Alchemy. I have to admit to not entirely understanding how Alchemy works, but I understand enough C to write a simple pricer in it. Here’s the relevant C-code (which is, in part, copied from Mike Chambers’. Stringecho.c sample) :. Header file for AS3 interop APIs. AS3 Val getPrice (. AS3 Val args ). AS3 Number (.

Approaching geekery in an ad hoc and improvisational manner. VAR, COVAR and COREL in Actionscript. Is a little daunting if you’ve never really thought about what these functions entail (or have forgotten), but essentially it boils down to this :. Correlation coeff between two random variables X and Y is defined as :. Correlation(X,Y) = covar(X,Y)/(sqrt(Var(X) * sqrt(Var(Y) ). Var(X) = covar(X,X);. Covar(X,Y) = E( X-xm)(Y-ym) ; where xm, ym are the population means. X = Y ). Xm : average (. Total = (.

Approaching geekery in an ad hoc and improvisational manner. Dtutil : Importing SSIS packages via batch scripting. Just a quick and simple task here. I got fed up of manually importing dtsx files into our SSIS file store so I looked into a scripting solution. This relies entirely on dtutil. Which is installed with SSIS. Written by admin in: Geek. Windows command shell fun. Only for slightly bizarre/masochistic senses of fun). I had discovered over the last few months that bits of my collection disappeare...

Approaching geekery in an ad hoc and improvisational manner. Windows command shell fun. Only for slightly bizarre/masochistic senses of fun). I’ve been out on a client site for a month or two and haven’t had time to update a lot. Now that I’m back in the office I decided to ease myself into things slowly by going through my usual backup routine and incidentally tidying up my music collection. S /b *.ogg. You can issue these as separate commands if you want, all that changes is the “% a” becom...Assuming ...

Approaching geekery in an ad hoc and improvisational manner. Rolling back a ClickOnce application. So, very simply, let’s say you have a publish folder with these files :. Example contents of the ClickOnce deployment folder. The *application file is the application manifest, which defines, among other things, the current version of the application and where its downloadable files are within the Application Files folder. If you drill down into that folder you might see a list of folders as in figure 2.

Approaching geekery in an ad hoc and improvisational manner. Hate the Actionscript Date class. Mostly because of the way it deals with local time offsets. When I create a new date instance, I generally don’t care about the local time zone settings. I’ll care about them when I have to combine it with other dates, sure, but at the time I set that value I want it to. That value. The AS date class thinks otherwise. To do that, you have to take this approach :. There’s no need for a superfluous DateForm...
