Where is array's length property defined?
...ss itself does, yes - because it holds a reference to a char[] (or did, at least; I don't know whether it still does, off-hand). So while a StringBuilder is responsible for more memory, its immediate size and layout are fixed.

...les. The collection of free variables is often called the environment, at least by programming-language theorists.
A closure is just an aggregate containing a function and an environment. In the Standard ML of New Jersey compiler, we represented one as a record; one field contained a pointer to...
Cross compile Go on OSX?
...
the same is true (at least in Bash) without env. I ran export GOOS=windows then GOOS=linux bash -c 'echo "GOOS: $GOOS"' then echo "GOOS: $GOOS". Does env provide greater compatibility with other shell dialects or with other platforms? If not it s...

Group vs role (Any real difference?)
...you to specify whether the collection at issue is a "group" or a "role" at least for the sake of discussion.
Some analogies might help. Framed in terms of set theory, when group alpha is a subset of group beta, then permissions alpha are a superset of permissions beta. Compared to genealogy, if gro...
Is using Random and OrderBy a good shuffle algorithm?
...(< 128), the algorithm is very biased (4-8%). With 3 values you need at least r.Next(1024). If you make the array bigger (4 or 5), then even r.Next(1024) isn't enough. I'm not an expert in shuffling and in math, but I think that for each extra bit of length of the array, you need 2 extra bits of ...
