...imple-talk.com/sql/t-sql-programming/ten-common-sql-programming-mistakes/
Now, this does have an example of later SQL Server optimiser versions managing CAST to date correctly, but generally it will be a bad idea ...

.c vs .cc vs. .cpp vs .hpp vs .h vs .cxx [duplicate]
...opular choice for C++ even with the disadvantage that it doesn't allow to know if the header can be included in C context or not. Standard headers now have no extension at all.
Additionally, some are using .ii, .ixx, .ipp, .inl for headers providing inline definitions and .txx, .tpp and .tpl for te...

What is a MIME type?
...IME type" keeps getting discussed in it. I have tried to look into it and know that it is Multipurpose Internet Mail Extensions (MIME) but no suitable explanation of how it relates to browser plug-ins, as in what I need to know about it for building plug-ins, is provided, please explain in clear and...
Why is list initialization (using curly braces) better than the alternatives?
...an call completely different functions, and this is an important thing to know. It can even result in calls that seem unintuitive. Saying that you should prefer {} by default will lead to people misunderstanding what's going on. This isn't your fault, though. I personally think it's an extremely poo...
Can an enum class be converted to the underlying type?
...
I think you can use std::underlying_type to know the underlying type, and then use cast:
#include <type_traits> //for std::underlying_type
typedef std::underlying_type<my_fields>::type utype;
utype a = static_cast<utype>(my_fields::field);
With th...
Is it safe to ignore the possibility of SHA collisions in practice?
... crashes on Earth within the next second, obliterating civilization-as-we-know-it, and killing off a few billion people? It can be argued that any unlucky event with a probability lower than that is not actually very important.
If we have a "perfect" hash function with output size n, and we have p ...
Does Haskell require a garbage collector?
...y unnecessary.
jhc actually uses a sophisticated form of escape analysis known as region inference. Consider
f :: Integer -> (Integer, Integer)
f x = let x2 = x * x in (x2, x2+1)
g :: Integer -> Integer
g x = case f x of (y, z) -> y + z
In this case, a simplistic escape analysis would ...
Difference between method and function in Scala

def apply(v1: T1, v2: T2): R
And that tell us all that there is to know about it. A function has an apply method which receives N parameters of types T1, T2, ..., TN, and returns something of type R. It is contra-variant on the parameters it receives, and co-variant on the result.
That varia...
