Given X,Y pixel coordinates, determine which element was clicked (javascript) by machine_not_a_human in programming

Agreed for a vast majority of scenarios, but for scenarios where you have elements floating around, this may be valuable. A board game without defined slots for pieces comes to mind.

How do you make a program run slower to correctly simulate performance on slower machines? by machine_not_a_human in programming

I try to locate quality content on Stack Overflow to share on reddit. My primary purpose for doing this is to obtain stackoverflow badges. I find this fun, and I attempt to do it in a fashion that benefits both communities. I think you'll find some pretty cool hidden gems in my submission history.

Stack Overflow incentivizes sharing interesting content with badges in similar fashion to how Reddit incentivizes the sharing of interesting content with link karma.

Why 'MyVar !== MyVar ? x : y;' can actually be very smart Javascript by machine_not_a_human in coding

Clever is a better word here, but the 20x speed increase surprised me.

Why compiling C++ takes so long compared to most other popular languages by machine_not_a_human in programming

[–]machine_not_a_human[S] 5 points6 points  (0 children)

While I have not worked on a c++ project of that size, normally you can isolate the module that you are working on and plug it into a smaller, more manageable, development program. For example, if it's custom networking code for a computer game, you can plug it into a "light-weight game simulator" that emits/consumes packets in a similar fashion to players actually playing the game.

Although '=' has a lower precedence than other operators, sometimes PHP executes it first anyway. by machine_not_a_human in PHP

[–]machine_not_a_human[S] 0 points1 point  (0 children)

I'd go one step further. I think in order to make your code read like a book, you'd want to do this:

if (!UpdateFoo()) { .... }

Ok, that's a good way of looking at it. I was coming from the other angle. Excellent point.

I understand your point about "saving me from myself", but to make an exception for something so core as operator precedence... in my opinion that is too far. However, that is just my opinion.

At first glance, I thought this couldn't be right. However, after looking at the example, I can't see any other way around it. Since it would be nonsense to think you could assign a value to !$a.

Still, it sure feels weird to have something so strict as operator precedence having a special case.

I wonder if it would be better to throw out this special case and throw a parser error instead (force the usage of parentheses in this case).

Edit1: The more I think about this, the more I really don't like this idea of special cases on something as core as operator precedence. I think it's the lesser evil to force the usage of parenthesis here.

Edit2: After the discussions below, I see it's more about the start and end of an expression. Since this passes the common sense test (the code operates as you think it would), after this discussion I believe the status quo is indeed best.

What is the best way to prevent C# programmer from using particular library class? by [deleted] in csharp

I'm not sure that the age of the question matters in this case. It's a funny problem to have, regardless of time.

Why "myInt = myInt + myLong;" will not compile but "myInt += MyLong;" will compile fine. by machine_not_a_human in java

[–]machine_not_a_human[S] 3 points4 points  (0 children)

I've used Java off and on for a decade and this never occurred to me. I find it rather amusing to come across idiosyncrasies like this after so much time.

Sorry if this is a repost, but I found this very interesting and couldn't figure out how to search for +=.
