Why does the C# compiler not fault code where a static method calls an instance method?
... that the compiler can't resolve the call to the instance method. In other words, the way that the compiler does the resolution is simplistic - it doesn't recognise the simple case like my example where there's no possibility that it can't resolve the call. The irony is: by having a single Bar() met...
Why not use exceptions as regular flow of control?

Boolean operators && and ||
... are correct that the "short-circuit" is the reason for preferring one. A word of warning though, make sure you are 100% sure they can only be length one. You can get really goofy bugs otherwise.

Using -performSelector: vs. just calling the method
...determine which selector to call a selector on the given object. In other words the selector need not be determined before runtime.
Thus even though these are equivalent:
[anObject aMethod];
[anObject performSelector:@selector(aMethod)];
The second form allows you to do this:
SEL aSelector...
Why am I merging “remote-tracking branch 'origin/develop' into develop”?
...your local branch can be "fast forwarded" to the upstream branch (in other words, if it hasn't diverged).
git rebase -p @{u} effectively moves the commits you've made but haven't yet pushed on top of the upstream branch, which eliminates the need to create the silly merge commits you're trying to av...

... was demonstrating that the author didn't understand the importance of the word 'average'. Many of the individual benchmarks are not 6.3 times faster. And if you use a different type of average you get a different value, so "6.3 x faster" is not an adequate summary of "geometric average is 6.3 x fas...
How many concurrent requests does a single Flask process receive?
...rrency we talk about in computer science is software concurrency.
In other words, there are layers of software implementation that abstract the bottom level CPU from us and make us think we are running code concurrently.
These "things" can be processes, which are units of code that get run concurre...
What are the differences between git remote prune, git prune, git fetch --prune, etc
...script that will remove all local branches that aren't tracked remotely. A word of caution: This will get rid of any branch that isn't tracked remotely regardless of whether it was merged or not.
