geometry - Calculate minimum distance between two lines and two arc -


i have 2 problem first how calculate minimum distance between 2 lines. details attaching image here.

enter image description here

in image describe line start , end point. have start , end point both lines not getting idea how calculate minimum distance between 2 lines.

another problem how calculate minimum distance between 2 arc. attaching image here

enter image description here

for arc have start, end , center point have start , end angle.

this link has lot more things - shortest distance between point , line segment

i got above link.

enter image description here

this issue facing now. in scenario how calculate minimum distance between 2 arc?

any idea how solve 2 issue?

distance between 2 intersecting lines 0

otherwise, want calculate endpoint of 1 of line other one. if want calculate distance between point , line :

it length of line segment joins point line , perpendicular line.

for arcs think arcs part of circles, distance between them distance between center points , minus radiuses.

can find more here: calculate minimum distance between 2 given circular arcs

example example

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
