I've been using django-mptt in my project for a while now, it's fabulous. Recently, I've found a need to override a model's save() method that uses mptt, and I'm getting an error when I try to save a new instance of that model:

I'm getting the error:
Exception Value: (1110, "Column 'about' specified twice")
As I was reviewing the Django error page, I noticed that the customizations the model User, seem to be appended to the List twice.

I was watching http://www.joelonsoftware.com/items/2011/06/27.html and laughed at Jon Skeet joke about 0.3 not being 0.3. I personally never had problems with floats/decimals/doubles but then I remember I learned 6502 very early and never needed floats in most of my programs. The only time I used…

Mathematically, consider for this question the rational number
8725724278030350 / 2**48
where ** in the denominator denotes exponentiation, i.e. the denominator is 2 to the 48th power. (The fraction is not in lowest terms, reducible by 2.) This number is exactly representable as a System.Double…

How can i format a Double to String in c# so as to have only two decimal digits?

I've seen the following (bizarre) Javascript rounding function in some legacy code. After googling for it I can see that it crops up in a number of places online. However I can't work out why the hard-coded values 8191 and 10485 are present.
Does anyone know if there's any sensible reason why these…
