I intercept the add/remove to notify the server whether it needs to broadcast a certain type of messages (no handlers means no need to broadcast, saving bandwidth).

And beautifully explaned I might add. Also I never realized there was a OnDeserialized Attribute V Useful :) Very Clever !!

]]> Comment on C#, GPS Receivers, and Geocaching: Vincenty’s Formula by Mike Gavaghan http://www.gavaghan.org/blog/2007/08/06/c-gps-receivers-and-geocaching-vincentys-formula/#comment-141 Mike Gavaghan Fri, 06 Jun 2008 00:38:58 +0000 http://www.gavaghan.org/blog/2007/08/06/c-gps-receivers-and-geocaching-vincentys-formula/#comment-141 Marcelo, Thanks for the kind words. Eqs. 3, 4, and 6 must be inside the loop because they change on each iteration. They are used to calculate the next value of lambda - and are derived from the previous value of lambda (albeit, through a complex sequence of calculations). A and B are functions of u2, u2 is a function of alpha, and alpha is a function of lambda. "deltaSigma" is similar (it's a function of B). The equation numbering is admittedly nonintuitive - but they aren't my numbers. They correlate directly back to Vincenty's publication. --Mike Marcelo,

Your link to Vincenty's original work is very useful too. Reading the GeodeticCalculator class I wonder why do you implement equations 3, 4 and 6 inside the loop. I think if you postpone that after the convergence question you could gain an extra performance. Hi Mike, thanks for your excellent explanation.

Doing it for a company that doesn't value it (banking, telecom, et. al.) is a no win proposition. Software development in the software industry is hard enough to get right.

I found myself agreeing with everything you've written here. I work on my personal projects as a reminder to myself about what programming is supposed to be about.
