=& to multiply, anyone?

[EnigmaticHat]

I'm going to need your badge and laptop InsanityIncarnate.

[Mephisto]

@ for matrix multiplication, anyone?

Oh wait...

[Sergius]

Too bad you can't overload the ternary operator tho, or turn arbitrary operators into ternary (quaternary?).

[Skyrunner]

I can write some code with no handlebars logic
// quadratic formula
x >> (-b == q(b<<b/4<<a<<c))-(2<<a)
// EDIT: missed a parens

[Putnam]

that is making me cry

Operator overloading: the feature that seems silly right up until you try to write your first vector library in a language without it.

It tends to go along the lines of this:

Code: [Select]

vector A, B, C;
...
// Right then; time to write some code using my vector math!
C = A.Multiply(A.Add(B)).Divide(B);
// Or wait, was that my in-place operation function, or one that returned a modified copy?
C = A.MultiplyCopy(A.AddCopy(B)).DivideCopy(B);
// I really hope I don't have to optimize this; I can barely tell what it's doing now.
...
// Some time later:
C.Multiply(A.MultiplyCopy(A.AddCopy(B)).DivideCopy(B).Subtract(B.AddCopy(C).MultiplyCopy(D)).MultiplyCopy(7.0f));
//  I think I'll just switch to a geography major and drink alcohol until I die
As opposed to

Code: [Select]

C *= (A*(A+B)/B) - ((B+C) * D) * 7.0f;
Which is quite the breath of fresh air when you switch back to a language which trusts you with a bottle of glue, rather than only giving you glue sticks.

For some reason this discussion made me think of this gem:

Code: [Select]

/proc/random_frequency()
    return 1337 //WHY -Doohl

Even though there are easy, built-in ways to get random numbers...

So I'm having an... interesting problem with Unity.

I have 2 scripts (script A and script B) attached to one GameObject, both scripts have a "OnTriggerEnter2D" callback. one script (script A) starts a co-routine that yields null and destroys itself (so it destroys itself the frame after being triggered).

For some unexplainable reason, about 2% of the time it will not call script B's OnTriggerEnter2D function for no apparent reason. it *should* trigger both of them (and it shouldn't matter what order, since I am destroying it *next* frame), but its not.

Adding in extra yields fixes the problem (I think), but then the object remains on the screen for a noticable time after being triggered.

From debugging, when script A is triggered, the destruction takes place the next frame 100% of the time (including when script B is not triggered).

I... have absolutely no idea what is going on here. Is there some simple logic thing I have missed or something?

[Thief^]

It *sounds* like a race condition, so maybe the order of the scripts running isn't guaranteed?

I assume unity has no "destroy at end of frame" concept.

[alexandertnt]

I *thought* it could have been some sort of race condition, thats why it yields and destroys itself next frame (to allow it to finish calling everything).

It also turns out that adding another yield did *not* actually fix the problem, so the callback sometimes isn't called even though its being destroyed 2 frames later.

This is an infuriating bug, there is only so many times you can jump into a fireball (with like a 2% chance to actually see the bug) before you go insane.

So, in my Operating Systems class, I'm having to build my own shell in C.

Never did I think it would be so difficult to create a ragged string array on the fly. Nor make getchar() play nice.

Picking up a new language in my Software Languages class, Unicon. It's the professor's baby language but it's pretty nice to use

A pain in the ass to compile from source on a Linux distro but the windows executable's nice and easy to work with.

For someone who's main skill in Programming is in C++, how hard is python to pick up?
