...is solution is that it doubles the overhead of every unique_ptr (they must all store the function pointer along with the pointer to the actual data), requires passing the destruction function every time, it can't inline (since the template can't specialize to the specific function, only the signatur...

...it test module is of the form test_*.py . I am attempting to make a file called all_test.py that will, you guessed it, run all files in the aforementioned test form and return the result. I have tried two methods so far; both have failed. I will show the two methods, and I hope someone out there ...

...e for the general case: Stream<T> stream = ...; // sequential or parallel stream Optional<T> last = stream.reduce((first, second) -> second); This implementations works for all ordered streams (including streams created from Lists). For unordered streams it is for obvious reasons u...

...nitializer list elements in the current revision of the language. Specifically, we have: typedef const E& reference; typedef const E& const_reference; typedef const E* iterator; typedef const E* const_iterator; const E* begin() const noexcept; // first element const E* end() const noexce...

I've seen there are actually two (maybe more) ways to concatenate lists in Python: One way is to use the extend() method: 9...

I'm looking for a way to get all rows as INSERT statements from one specific table within a database using pg_dump in PostgreSQL. ...

C++11 allows inline namespace s, all members of which are also automatically in the enclosing namespace . I cannot think of any useful application of this -- can somebody please give a brief, succinct example of a situation where an inline namespace is needed and where it is the most idiomatic s...

... a signed and unsigned char have a useful meaning (generally equivalent to uint8_t and int8_t). When used as a character in the sense of text, use a char (also referred to as a plain char). This is typically a signed char but can be implemented either way by the compiler. * Technically, a char ca...

...ith dynamic programming, you store your results in some sort of table generally. When you need the answer to a problem, you reference the table and see if you already know what it is. If not, you use the data in your table to give yourself a stepping stone towards the answer. The Cormen Algorithms ...

...loop, or map, or a list comprehension, etc. in Python, the next method is called automatically to get each item from the iterator, thus going through the process of iteration. A good place to start learning would be the iterators section of the tutorial and the iterator types section of the standar...
