I do like to wrap $_SESSION, $_POST, $_GET, and $_COOKIE into OOP structures. I use this method to centralize code that handles sanitation and validation, all of the necessary isset () checks, nonces, setcookie parameters, etc. It also allows client code to be more readable (and gives me the illusion that it’s more maintainable). It … Read more
Apparently, ES6 doesn’t need namespacing because each file is a separate module. Not exactly. Each module does have its own scope, that is correct, but not every file is a module. There still are scripts in ES6 that work just like those from ES5, and are executed in the global scope. In those scripts, you … Read more
A possible solution is to implement a custom Django middleware, as described in https://docs.djangoproject.com/ja/1.9/topics/http/middleware/. You could initialize the HTTP connection pool in the middleware’s __init__ method, which is only called once at the first request. Then, start the HTTP request during process_request and on process_response check it has finished (or wait for it) and append … Read more
Global variables should be avoided because they inhibit code reuse. Multiple widgets/applications can nicely live within the same main loop. This allows you to abstract what you now think of as a single GUI into a library that creates such GUI on request, so that (for instance) a single launcher can launch multiple top-level GUIs … Read more
The default storage duration is static, but default linkage is external. You’re not the only one to find it a bit confusing. The C Book (always a good reference) says: “You’ll probably find the interactions between these various elements to be both complex and confusing: that’s because they are!” The section with that quote, Declarations, … Read more
In header file only do namespace gi { extern MapInformation mapInf; }; In CPP file provide the actual definition. namespace gi { MapInformation mapInf; }; It will work as you intend. If you are using the MapInformation across dynamic link library boundaries you might have to link against the library that includes the definition cpp … Read more
Flanagan’s “JavaScript – The Definitive Guide” gives the following on page 653: var variables = “” for (var name in this) variables += name + “\n”;
For that you need to use Less or Sass which are CSS Dynamic languages. here’s some comparison between both technologies.
you have to define the global var in the second function as well.. // global scope $ref_id = 1; grabReferral($rid){ global $ref_id; $ref_id = $rid; } someOtherFunction(){ global $ref_id; sendValue($ref_id); } felix
Compact version using lambda function: void foo() { static bool once = [](){ cout << “once” << endl; return true; } (); cout << “foo” << endl; } Code within lambda function is executed only once, when the static variable is initialized to the return value of lambda function. It should be thread-safe as long … Read more
