OT: "web size" (was: Re: Rename anaconda to cryptoconda?)

[Karel Volný]

Hi,

sorry to bother your circles, but one paragraph catched my eye ... it is 
strongly offtopic here, but I couldn't resist to try to educate people - who 
knows, maybe someday ... I'll live long enough until browser developers will 
finally understand CSS ...

this is not 100% true

please take a look at http://www.w3.org/TR/CSS21/syndata.html#value-def-length 
- especially the image http://www.w3.org/TR/CSS21/syndata.html#img-pixel1

"For reading at arm's length, 1px thus corresponds to about 0.26 mm (1/96 
inch)."

so, if "pixel density of his display" is very different from 96 DPI, the CSS px 
unit should *not* be used 1:1 as display pixels

while you may consider setting base font size for reading at arms lenght to 
3.38 mm rude in general, it surely does NOT "rudely thwart the web's inherent 
adaptability" - it *should* adapt to the user's device, and it is just the 
webbrowser developers' arrogance(*) if it doesn't adapt, go nag them

(*) I'd write "laziness" or something less offensive if I hadn't already tried 
in vain with Gecko and KHTML
