Haskell: How is pronounced? [closed]
...
Sorry, I don't really know my math, so I'm curious how to pronounce the functions in the Applicative typeclass
Knowing your math, or not, is largely irrelevant here, I think. As you're probably aware, Haskell borrows a few bits of terminolo...
Store boolean value in SQLite
...
@joce Actually, integers 0 and 1 (as well as NULL) are encoded directly in row data type declaration. So it's zero bytes per boolean, if you only count the actual data storage, which is awesome. If you count per-column-per-row bookkeep...
Is floating-point math consistent in C#? Can it be?
...to way to make normal floating points deterministic in .net. The JITter is allowed to create code that behaves differently on different platforms(or between different versions of .net). So using normal floats in deterministic .net code is not possible.
The workarounds I considered:
Implement Fixe...

What is array to pointer decay?
... decay doesn't happen.
If you're passing an array by value, what you're really doing is copying a pointer - a pointer to the array's first element is copied to the parameter (whose type should also be a pointer the array element's type). This works due to array's decaying nature; once decayed, size...
What exactly is Type Coercion in Javascript?
...with type systems that take the first position about its rules are colloquially referred to as “strongly typed” languages. They are strict about not letting you break its rules. Those that take the second approach (such as JavaScript) are referred to as “weakly typed” or “loosely typed” ...
Calculating Pearson correlation and significance in Python
...trictly speaking, Pearson's correlation requires
that each dataset be normally distributed. Like other correlation
coefficients, this one varies between -1 and +1 with 0 implying no
correlation. Correlations of -1 or +1 imply an exact linear
relationship. Positive correlations imply that as x in...
Why is lock(this) {…} bad?
...
It is bad form to use this in lock statements because it is generally out of your control who else might be locking on that object.
In order to properly plan parallel operations, special care should be taken to consider possible deadlock situations, and having an unknown number of lock en...
