Covid, False Positives & Bayesian Probability
This is a repost from 2009. It talks about breast cancer, but applies equally well to Covid testing, given the high percentage of false positives (not to mention the more worrisome false negatives). We simply are not wired well for probability…
Yudkowsky poses the following canonical problem:
1% of women at age forty who participate in routine screening have breast cancer. 80% of women with breast cancer will get positive mammographies. 9.6% of women without breast cancer will also get positive mammographies.

MonkeyCache step by step
The amazing James Montemagno of Xamarin/Microsoft has done it again. He has created an incredibly simple cache, named MonkeyCache, that you can get up and running very quickly.
In this post I will walk through setting up and using the cache, step by step.

An Alert From the ViewModel
Quite often we want to send an alert from the view model, but you can only do so from the view. We’ve tackled this problem in the past but we think there is room for a simplified and clear step by step explanation.

Code Snippets can save you from repetitive (boring) tasks. Visual Studio comes with a great many code snippets, perhaps the most often used is ctor which creates an empty constructor.
You can also create your own. Here is one I use a lot. It creates something that looks like this:
