How does Yahoo’s Smush.It work and why doesn’t everyone use it?
I’ve recently come across an application by Yahoo called SmushIt. Apparently it does lossless compression on images. Sometimes the image size is reduced by as much as 90%. This of course has major implications when working on the web since it greatly improves performance on pages that have a lot of images. Now I’m sure there are other applications like this one out there but I’ve never heard of anyone actually doing lossless image compression in web development.
(jQuery) What is wrong with methods such as .append?
tl;dr: What is wrong with the efficiency of methods such as .append() and what can be alternatives to this?
Bottleneck performance in ECS
I’ve been looking into building an entity-component-system. Basically, an entity is just an id wrapped around a struct, components are data belonging to that entity(and reference said id), and systems are the code. Entities and components are all stored inside arrays, to allow fast iteration over each.

When trying to find out if a number is even or odd: AND 1 or OR 0
I recently learned of the trick for finding out if a binary number is odd or even.

Why are return values from compare functions in many languages defined loosely?
Many languages define that compare functions should return ANY negative value, zero, or ANY positive value. Is there some reason that it shouldn’t be clearly defined as -1 0 and 1? Does a wide range in possible return values help more advanced algorithms to work more efficiently? If so, what algorithms work this way?

Closest Point to Moving Target
I have a target which is constantly moving, and only its current position is ever known. I also have about one hundred objects surrounding it, and for each of these only the current position is known.
