Code Review of Ferguson’s Model for CV19

[planomustang]

Let me put somethings, upfront. I have a bachelor's degree in Computer Science. I have a master's degree in Mathematics. I worked for nearly 30 years at Raytheon/E-Systems, as a Software Engineer, doing everything from real-time control systems, digital signal processing, scheduling algorithms, etc. Over that time, I became a senior-engineer, which means I managed teams of engineers to solve very complex problems. I became a real business man.

The computer models for Climate Change are especially, iffy. They cannot account for rounding errors in floating-point arithmetic, that permeates those models. This is just an example of why folks should not trust computer models.

A Code Review of Ferguson’s Model.

This is one of the models that is driving Trillion Dollar decisions, and it is driving decisions of how free we are as a people. The model is crap, and I would have been fired from Raytheon/E-Systems, if I used their level of quality control.

Read this article. Pass it on to your Engineering friends. This code needs to be peer reviewed, by professionals.

Floating-point arithmetic always tripped me up as well..

I could never understand diffy-q either.

I'll bet the same ****ty models/modelers also calculate global warming.

The only models I study wear 2 piece swimsuits, and generally with the top piece of “data” missing

Oh man, now you've really messed up! Not only did you suggest reviewing data for the Wuhan testing with an analytical perspective to determine it's accuracy, but you also questioned the Global Warming Bible??

Obviously you hate old people, dogs, and children.

Interesting. Didnt look at the code, but depending on the algorithms they use, it's entirely possible to have non-deterministic outputs if you don't control all parameters. Something like the tribes algorithm for instance can be made deterministic, but unless intentionally done it will probably be non-deterministic. Of course everything else surrounding it sounds typical of bad practice, like the code being a single 15k line file, so it's already suspect.

Al Gore invented floating point arithmetic.
