Creating an index on a table variable
...TP 3.1 it is now possible to declare filtered indexes for table variables. By RTM it may be the case that included columns are also allowed but the current position is that they "will likely not make it into SQL16 due to resource constraints"
/*SQL Server 2016 allows filtered indexes*/

Finding all cycles in a directed graph
...nected components and all cycles (The cycles c-d and g-h won't be returned by Tarjan's alg)(@batbrat The answer of your confusion is also hidden here: All possible cycles are not returned by Tarjan's alg, so its complexity could be smaller than exponential). The Java-Code could be better, but it sav...
“using namespace” in c++ headers
...include s in their .h files. This seems to me to be dangerous since then by including that header in another program I will get the namespace imported into my program, maybe without realizing, intending or wanting it (header inclusion can be very deeply nested).

Once you have this working, you can look at where CMake puts things by default, and only if you're not satisfied with the default locations (such as the default value of EXECUTABLE_OUTPUT_PATH), modify only those you need. And try to express them relative to CMAKE_BINARY_DIR, CMAKE_CURRENT_BI...
Difference between Hashing a Password and Encrypting it
...gned to prevent the occurrence of collisions. You can attack a secure hash by the use of a rainbow table, which you can counteract by applying a salt to the hash before storing it.
Encrypting is a proper (two way) function. It's reversible, you can decrypt the mangled string to get original string ...
Is the pImpl idiom really used in practice?
I am reading the book "Exceptional C++" by Herb Sutter, and in that book I have learned about the pImpl idiom. Basically, the idea is to create a structure for the private objects of a class and dynamically allocate them to decrease the compilation time (and also hide the private implementatio...
