Can C++ code be valid in both C++03 and C++11 but do different things?
...ructors are considered. The applicable constructors are enumerated and the best one is chosen through overload resolution (13.3, 13.3.1.7). If a narrowing conversion (see below) is required to convert any of the arguments, the program is ill-formed
This and many more instance are covered in the dr...
is there a css hack for safari only NOT chrome?
...much actual standard code is not due to version changes) future proof. The best plan is if you are going to use a css hack, use it only as a temporary fix in order to buy time to make a more official cross-browser update.

Xamarin 2.0 vs Appcelerator Titanium vs PhoneGap [duplicate]
...rm. Platform-specific code should exist for these use cases to provide the best possible experience.
So for those reasons, Titanium is not an attempt at “write once, run everywhere”. Same as Xamarin.
Titanium are going to do a further step in the direction similar to that of Xamarin. In practi...
What is a stack trace, and how can I use it to debug my application errors?
...treat it as an ArithmeticException and probably do the wrong thing. In the best case you still miss that there was a NullPointerException. Stuff like that makes debugging much harder, so don't do that.
TLDR
Figure out what is the cause of the exception and fix it, so that it doesn't throw the exc...

What Haskell representation is recommended for 2D, unboxed pixel arrays with millions of pixels?
...
For multi-dimensional arrays, the current best option in Haskell, in my view, is repa.
Repa provides high performance, regular, multi-dimensional, shape polymorphic parallel arrays. All numeric data is stored unboxed. Functions written with the Repa combinators a...
List of Big-O for PHP functions
...the Big-O of the functions. It's an amazing free program that can find the best fitting function for arbitrary data.
EDIT:
For those who doubt that PHP array lookups are O(N), I've written a benchmark to test that (they are still effectively O(1) for most realistic values).

Is a statically-typed full Lisp variant possible?
...ly many ways around this, though it's not obvious to me which would be the best one.
EDIT: Oh, so with a bit of googling, I found Qi, which appears to be very similar to Lisp except that it's statically typed. Perhaps it's a good place to start to see where they made changes to get the static typi...
RabbitMQ and relationship between channel and connection
...tatus, as TCP does not contain anything in and of itself to do this.
It is best to have a dedicated thread manage reads and writes to the underlying TCP socket. Most, if not all, RabbitMQ clients do this. In that regard, they are generally thread-safe.
Relatively speaking, connections are "expensive...
