Is there a difference between foreach and map?
...++, for example, foreach returns the operation it originally received. The idea is that the operation might have a state, and you may want that operation back to inspect how it evolved over the elements. map, too, may or may not return a value. In C++ transform (the equivalent for map here) happens ...
Return array in a function
... could return a reference to it if you want, but that's not really a great idea, since it sort of implies that you're getting something different from what you passed.
If you really do need a new instance of the collection, but want to avoid having it on the stack (and all the copying that entail...
Boolean method naming readability
....Name()) without any comparison value, so why is if (user.Exists()) a good idea purely because that property/function is of boolean type and you can rename the function/property to read more like natural english? Is it so bad to follow the same pattern we use for other types other than booleans?

For instance, I have setup DiffMerge to be the tool for Git merge, setting a ruleset which allow that merge tool to ignore eol for certain type of fi...
Difference between malloc and calloc?
...t does zero-initialize the memory; this is not the primary difference! The idea of calloc is to abstact copy-on-write semantics for memory allocation. When you allocate memory with calloc it all maps to same physical page which is initialized to zero. When any of the pages of the allocated memory is...
Fluid width with equally spaced DIVs
...n addition to the calc() function, media queries are necessary.
The basic idea is to set up a media query for each #columns states, where I then use calc() to work out the margin-right on each of the elements (except the ones in the last column).
This sounds like a lot of work, but if you're using...
OSGi, Java Modularity and Jigsaw
...s a microservices architecture, but I know what you're saying. For me, the idea of modelling every service as a process is a much more complex problem, in terms of management and security and comms overhead. OSGi is simpler and faster.
