Should I return a Collection or a Stream?
...at most of the time, Stream is the right answer -- it is more flexible, it doesn't impose usually-unnecessary materialization costs, and can be easily turned into the Collection of your choice if needed. But sometimes, you may have to return a Collection (say, due to strong consistency requirements...
What is the difference between Serializable and Externalizable in Java?
... The "java-manual" in github.com/eishay/jvm-serializers/wiki does not use Externalizable, which would imply using ObjectOutputStream. See github.com/eishay/jvm-serializers/wiki/ToolBehavior for a link to the code. Instead, it is hand-written code that uses DataOutputStream, so it doesn...
E731 do not assign a lambda expression, use a def
...:
a.f = lambda x: 2 * x

C++11 rvalues and move semantics confusion (return statement)
... @NoSenseEtAl: There is no temporary created on the return line. move doesn't create a temporary. It casts an lvalue to an xvalue, making no copies, creating nothing, destroying nothing. That example is the exact same situation as if you returned by lvalue-reference and removed the move from ...

};
setTimeout(function() {
l.value+= 'log in\n';

Why can't the C# constructor infer type?
...siderable -- that's not sufficient to have a feature implemented. Not only does the feature have to be a net win, it has to be a large net win compared to all the other possible features we could be investing in. It also has to be better than spending that time and effort on bug fixing, performance ...
How do CUDA blocks/warps/threads map onto CUDA cores?

How can I export tables to Excel from a webpage [closed]
...nd most of all very EASY to understand. It's a win-win. The one thing it does have limits on, though, is strict formatting of columns.

Why should I prefer single 'await Task.WhenAll' over multiple awaits?
...
@usr I was curious still to know if WhenAll doesn't do clever things like conserving the same SynchronizationContext, to further push its benefits aside from the semantics. I found no conclusive documentation, but looking at the IL there are evidently different impleme...
