Can Powershell Run Commands in Parallel?
...o do some batch processing on a bunch of images and I'd like to do some parallel processing. Powershell seems to have some background processing options such as start-job, wait-job, etc, but the only good resource I found for doing parallel work was writing the text of a script out and running thos...

Using Kafka as a (CQRS) Eventstore. Good idea?
...an event store however to quote their intro:
The Kafka cluster retains all published messages—whether or not they
have been consumed—for a configurable period of time. For example if
the retention is set for two days, then for the two days after a
message is published it is available f...
Should a function have only one return statement?
...f-else statements, each with a return? That is nothing. Such a thing is usually easily refactored. (atleast the more common single exit variation with a result variable is, so I doubt the multi exit variation would be any more difficult.) If you want a real headache, look at a combination of if-els...
Which method performs better: .Any() vs .Count() > 0?
...le<T> sequence.
For just IEnumerable<T>, then Any() will generally be quicker, as it only has to look at one iteration. However, note that the LINQ-to-Objects implementation of Count() does check for ICollection<T> (using .Count as an optimisation) - so if your underlying data-sou...

As of jQuery 1.4.3 HTML 5 data-

What are the Dangers of Method Swizzling in Objective-C?
...
I think this is a really great question, and it's a shame that rather than tackling the real question, most answers have skirted the issue and simply said not to use swizzling.
Using method sizzling is like using sharp knives in the kitchen. So...
Should everything really be a bundle in Symfony 2.x?
...,
etc.
This way, you would put in the AppBundle only that stuff that is really Symfony2 specific. If you decide to switch to another framework later, you would get rid of the Bundle namespace and replace it with the chosen framework stuff.
Please note that what I'm suggesting here is for app specif...
Are there any worse sorting algorithms than Bogosort (a.k.a Monkey Sort)? [closed]
...input list being in the exact order
it's in is 1/(n!). There is such a small likelihood of this that it's
clearly absurd to say that this happened by chance, so it must have
been consciously put in that order by an intelligent Sorter. Therefore
it's safe to assume that it's already optimally...
Why does this C++ snippet compile (non-void function does not return a value) [duplicate]
...means that the compiler is not obligated provide an error nor a warning usually because it can be difficult to diagnose in all cases. We can see this from the definition of undefined behavior in the draft standard in section 1.3.24 which says:
[...]Permissible undefined behavior ranges from igno...
