ruby on rails - why is it dangerous to use find with will_paginate? -

i found next in faq after sorting out bug.

it’s possible trying paginate static array instead of performing paginated query in database. instance, chaining paginate phone call after active record find or methods wrong:

the above line homecoming desired result defeats purpose of pagination. here, find query first load records database, unsafe , should avoided.

my question why unsafe paginate find?

pagination meant prevent unnecessary db load: want elements db, load them.

using find load kind of sort.

dangerous == heavy db load , potential crash.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
