Sometiems you just have to try even harder to get your Annonces I guess vv

It's worse than that.

Turns out $photoList is a global variable that gets declared and transformed inside getAnnonces(). In fact, it is returned by the function, so all you'd think this does is assign the variable to itself for some reason.

Well, it would, if the original programmer would have thought of declaring it as global outside of the function's scope. $photoList exists as a global variable inside the function, but has a local scope outside of it. If this isn't some kind of meta-obfuscation I don't know what it is.

Can somebody explain to me why my old code:

code:

enum Foo { FOO_1, FOO_2 };

string GetInfo(Foo foo){
  switch(foo) {
    case FOO_1: return foo1;
    case FOO_2: return foo2;
  }
}

was changed to

code:

string GetInfo(Foo foo){
  stringstream stream;
  switch(foo) {
    case FOO_1:
      stream << this->foo1;
      break;

    case FOO_2:
      stream << this->foo2;
      break;

    default:
      return "";
  }
  return stream.str();
}

because I'm seriously :psypop:

Make a big project? Just edit test.c with a text editor (ever tried actually typing code into a terminal? ugh), compile, and run it.

edit:

No, I'm not. If you add "-ldl" to the gcc command, you never need worry about using a dynamic library function:

code:

typedef double (*math_funcp)(double);

    void *initializer = dlsym(libm, "sin");
    math_funcp sin_func = *((math_funcp*)(&initializer));
    printf("sin(0.6) = %f\n", (*sin_func)(0.6));
    dlclose(libm);

    return 0;

Dear former intern: Just because .NET allows you to pass any object in the sender field of the event, does not mean you should use it to pass any arbitrary data. The first google result of "C# Custom Event" shows you exactly how to pass in custom event args.

Also, if your dialog only contains an ok and cancel button, you don't need to fire an event on when ok is pressed. Use the Dialog Result instead.

I got no code to show, but I've just found out about this bug:

A coworker of mine was saving hours in a database and chose to use the complete timestamp format (YYYY:MM:DD HH:mm:SS). However, he built the date using mktime() before sending it to the database. When there are parameters missing, mktime() completes them with the local date and time. For some reason, this made it so the main site would show an event's hour as right or wrong depending on the time of the day it was saved on in the admin panel.

I still don't really get how or why this all happens, but it made my day hell.
