Yeah, Nim is my favourite language currently! The expressivity and succinctness of Python with the speed of C, plus useful metaprogramming constructs. I recommend everyone to give it a go!

Sorry if you found the title condescending. In the intro section I also admit that I was ignorant about the whole gamma topic a few weeks ago. But I think it's an important topic, hence the title. Of course, 10 different people have 10

Thanks man, I'm a bit obsessed with these things and have spent way too much time on it. I'm glad someone notices and appreciates these details! :)

As arguably vision is the most important sensory channel in human-computer interaction, I'd say it doesn't hurt for all coders to have at least a vague understanding of gamma. I think it should be part of the "basic education

I'm glad you enjoyed reading the article. I completely agree on not really having a "right" way to blend gradients. For that reason I almost ended up omitting the gradient example from the article because doing it "corr

The world wouldn't end without computers either, or in fact, without humans, so this is a moot point... :) As I mentioned in the article, you can get away with working directly in sRGB in some cases (general image processing, non-photo

Your exactly right, my bad... I'll correct the article later today (and I'll also remove the word 'logarithmic' from a few places). Thanks!

I get a similar behaviour on my Android phone. As I mentioned in the article, that example doesn't work on most phone LCD screens. Try it on a real desktop monitor!
