Funny story! I'm an undergrad Computer Science student who received this postcard raytracer from my Pixar recruiter back in November when they visited my school (CMU). To try and woo my recruiter, I changed the "PIXAR" text

What a cool little mystery, and article! I'm glad that the answer is actually quite satisfying and poetic (and not, for example, some mundane artifact in manufacturing the bollards). > Still, a question does remain, one that might

A "max heap" is a heap that has O(1) access of the maximum priority element, as opposed to a "min heap" which returns the lowest priority. It's largely a semantic distinction, as a max heap = a min heap with negati

This is correct. What happens when you are trying to rely on malloc'd memory for sensitive calculations? Reading an invalid pointer is undefined behavior. I see no reason why "it almost never works" to check for NULL and a

I think Microsoft is trying (and, so far, succeeding) to consume this market with their C#/.NET offerings. Their open-sourcing of .NET Core and their commitment to cross-platform makes C# (which, of course, has similar syntax and stan

The whole article is tongue-in-cheek. It's relevant mostly because it's funny and partially because it provides context. Also, later in the same paragraph: > For Microsoft to trot this out during WWDC is a real thunder-steale

Excellent writeup. I would be curious as to the specific considerations given to a heap allocator on the GPU. Related: I'm not too familiar with Wine patches - what is the easiest way to view the final source code of this patch?
