Just the other day, there was a highly relevant tidbit on Freakonomics about the perverse incentives at play in meetings:
http://www.freakonomics.com/2012/02/13/ball-hogs-and-long-meetings/
To summarize: in general, people judge the competence of others at meetings based on how much they talk, rather than the quality of what they say. The consequence is that people have a strong individual incentive to waste time on trivialties, which degrades the usefulness of the meeting. Additionally, groups tend to strongly favour the first thing which is suggested, without properly considering alternatives, which leads to a tendency towards poor decision making.
Meetings: Where Work Goes to Die
How many meetings did you have today? This week? This month? Now ask yourself how many of those meetings were worthwhile, versus the work that you could have accomplished in that same time. This might lead one to wonder why we even have meetings at all. At GitHub we don't have meetings...
It's very possible that I'm being overly prickly about terminology, but I have to take exception to calling anti-aliasing in general a 'hack'.
Aliasing is a well-understood artefact of sampling. If your continuous ('infinite resolution') image contains frequency components above the nyquist frequencies of sampling, aliasing occurs. You remove aliasing by increasing your sampling frequency, or removing those high frequency components before sampling. (Or you sample above your nyquist frequency, remove high frequency components, and then resample, which is SSAA).
Anti-aliasing (in general) is an analytically rigorous solution to a well-understood problem. This is not the description of a 'hack'.
(The things people do to fake anti-aliasing because the real thing is too expensive, on the other hand...)
Fast Approximate Anti-Aliasing (FXAA)
Anti-aliasing has an intimidating name, but what it does for our computer displays is rather fundamental. Think of it this way -- a line has infinite resolution, but our digital displays do not. So when we "snap" a line to the pixel grid on our display, we can compensate by imagineering partial ...
