My favorite part of that "article" was the lensbaby ad that so ironically loaded right in the middle. 
Thanks for the post.

Interesting, but getting 5/5 soft on the right is not significant.

A very interesting article, but I do have some issues with the author's assumptions of manufacturing tolerances. I work in manufacturing and am very familiar with the equipment used in many different plants. They are VERY accurate- orders of magnitude more accurate than the 20 micron that the author uses. I'm talking about sub-nanometer resolution in the newer manufacturing equipment (actually, the output of these machines need to be at this level- so the machines themselves have even tighter tolerances). And these super-accurate machines are getting more and more common as older equipment is being decommissioned.
I liked the explanation of tolerance stacking- he did not even mention the accuracy of the sensor thickness, how accurately does the sensor get mounted to the sensor plate- how accurately is this plate mounted to the camera, etc. There are a LOT of possibilities for error.
What I took from the article: Pixel peeping will only drive you crazy.
I enjoyed it, thanks,
Matt

A horrible term. Normally used by schoolboys here in the UK.

... yep, definitely not PC this side of the pond. I had assumed it different over in the New World
(short for spastic an archaic, and pejorative word used to describe someone with cerebral palsy)

It's quite different here. http://en.wikipedia.org/wiki/Spastic Before I dropped out, it was probably in the top 10 of casual semi-derogatory words used in middle and high school. I don't think the etymology as it applies to the use on your side "of the pond" is applicable. Kinda like the phrase you chaps use to mean asking for a cigarette (which would be questionable in my neck of the woods)

Yep, not PC. It does refer to Cerebral Palsy, something not understood by (most) schoolboys, still a vile expression. Particularly if you are an adult.

Steve, I'm the same age as you and that's a term I haven't heard since I was a schoolboy. Never used in a nice way. I thought it faded away, at least over here.
Cultural differences I suppose.

Precisely. Brings to mind the David Howard incident.

The term "spaz" has been used for a long time outside of the context of referring to cerebral palsy.
Many older people think that the work "sucks" refers to felatio, but derogatory terms like "spaz" and "suck" have been modified by use so that the origin of the term is not referenced by the words in their new context. Eventually a word becomes so modified that one cannot tell what it means except by context. The famous four letter word is one such word, and its meaning can range from a powerful insult: "**** you and the horse you rode in on", to an invitation to romance: "let's **** like a couple of minks babe!"
Using the term "spaz-out" means to 'not remain calm' in the context that the writer used.

This is probably all gonna be deleted. But I gotta say, well done Chris.. what I wanted to say but am too dumb to verbalize (typize?).

I too was astonished at the casual use of the word, the more so as the language filter has problems with a variety of shovel or sp@de and with most of the word sn1gger.

Born & raised in the US I've never considered 'spaz' as anything rude, just a normal word like 'moron'.

I think it's a little hilarious that most of the responses have been about the word spaz, Ever since I was a little kid the word spaz just means freak out.
Like have a spasm, like a wild outburst. If you choose to believe that my use of teh word was meant to make fun of those with disabilities then I can't do much about that. Have fun with that.

Spastic people are not 'bad' or 'stupid'. Please don't use it like that.
