From MSDN: Each database has a counter that is incremented for each insert or update operation that is performed on a table that contains a rowversion column within the database. This counter is the database rowversion. This tracks a relative time within a database, not an actual time that can be associated with a clock. … Read more
I have worked with Cocoa / Obj-C on and off over the years. As of 2010 I find it quite limiting compared to WPF / NET Framework. I will list some of the differences I’ve found, and you can judge for yourself. Markup language When I design in WPF I get markup that is very … Read more
You’re looking for the Max function I think…. var c = Math.max(a, b); This function will take more than two parameters as well: console.log(Math.max(4,76,92,3,4,12,9)); //outputs 92 If you have a array of arbitrary length to run through max, you can use apply… var arrayOfNumbers = [4,76,92,3,4,12,9]; console.log(Math.max.apply(null, arrayOfNumbers)); //outputs 92 OR if you’re using ES2015+ … Read more
Here’s a way in C++11, using std::initializer_list: #include <algorithm> #include <initializer_list> template <typename T> bool is_in(const T& v, std::initializer_list<T> lst) { return std::find(std::begin(lst), std::end(lst), v) != std::end(lst); } with that, you can do: if (is_in(num, {1, 2, 3})) { DO STUFF } It is not very efficient though when not used with built-in types. int … Read more
Use the === operator, from the Swift documentation: Swift also provides two identity operators (=== and !==), which you use to test whether two object references both refer to the same object instance.
You can always “cast” it >>> tuple([1, 2]) == (1, 2) True Keep in mind that Python, unlike for example Javascript, is strongly typed, and some (most?) of us prefer it that way.
Play! is a breath of fresh air into Java and bypasses all the Enterprise cruft that has evolved over the years. Even the namespace is just play not com.playframework. It is supposed to be an answer to Rails, Django etc and is MVC based. It is needed for Java to stay relevant in all but … Read more
Update As Martin R states in the comments, tuples with up to six components can now be compared with ==. Tuples with different component counts or different component types are considered to be different types so these cannot be compared, but the code for the simple case I described below is now obsolete. Try this: … Read more
Quoting the doc (MDN): Equal (==) If the two operands are not of the same type, JavaScript converts the operands then applies strict comparison. If either operand is a number or a boolean, the operands are converted to numbers if possible; else if either operand is a string, the other operand is converted to a … Read more
