You seem to be talking about a different kind of leakiness. In my mind, there are two kinds: conceptual and performance leakiness. You are talking about the latter. Pretty much any non-trivial system on modern hardware leaks performance det

I guess what I mean is styles besides gothic (undecorated strokes of even thickness) and those that mimic traditional calligraphy. I see a lot of other forms for Latin scripts, but for Arabic, CJK and Indian scripts most typefaces fall into

I didn't phrase it well. I was specifically talking about the Baloo sample and how the typographic style is the same across scripts. Sorry, I am a layman, so I don't know the proper terms, but I mean the similar stroke weight and

I always wondered why many non-Latin (mostly cursive) scripts have little variation across different typefaces. Maybe I wasn't looking hard enough? Well, the article mentions a similar observation by a Sri Lankan typographer, so I gues

I can't say anything about JSON serialization performance as I don't have experience with it. Your other points, though, seem a little handwavy to me. Or maybe I am reading them wrong. > A tiny, somewhat extreme example: Swift

Did you compare it to a roughly equivalent Objective-C program? The top four entries in your profile data show retain, release and objc_msgSend. You will have those in Objective-C too. Maybe to a different degree? That's also why I am

I can't speak for other people's code, but I regularly profile and read the machine code generated by the Swift compiler, at least for my hot loops. If you know what you are doing (use the right annotations and optimizer flags), e
