when triaging bugs release, criteria typically used determine whether bug fixed release? the cannonical article on my life code economist , eric sink. it's worth reading article, if want summed in checklist: when bug happens, how bad impact? - severity how bug happen? - frequency how effort required fix bug? - cost what risk of fixing bug? - risk

what happens identical items in sort? (sorting algorithm) example following list after has been sorted in ascending order: (f, g, a, r, s, g, a, x) it depends on sorting algorithm use. some algorithms stable means equal distinct items stay in same order started. others unstable means order may change. in example, you'd end (a, a, f, g, g, r, s, x) can't tell difference between equal elements. suppose instead start (f1, g1, a1, r1, s1, g2, a2, x1) , sort first letters. stable sort guarantee ended (a1, a2, f1, g1, g2, r1, s1, x1) - whereas unstable sort end (a2, a1, f1, g1, g2, r1, s1, x1) or similar. see wikipedia sorting entry more information, , details stability of various algorithms.

i'm using python, , insert string text file without deleting or copying file. how can that? unfortunately there no way insert middle of file without re-writing it. previous posters have indicated, can append file or overwrite part of using seek if want add stuff @ beginning or middle, you'll have rewrite it. this operating system thing, not python thing. same in languages. what read file, make modifications , write out new file called myfile.txt.tmp or that. better reading whole file memory because file may large that. once temporary file completed, rename same original file. this good, safe way because if file write crashes or aborts reason, still have untouched original file.

i using tortoisesvn manage couple of projects have on go @ moment. when first moved source control wasn't sure how should laid out ended putting each project own repository. i wondering idea me move them 1 big repository , have them split project folders? else do? at moment none of them share common code may in future. make easier manage if together. thanks. depends extent mean "project". i have general local repository containing random bits of stuff write (including website, since it's small). single-user local svn repository not going suffer noticeable performance issues until you've spent lot of years typing. time svn faster anyway. i've yet regret having thrown in 1 repository, though of stuff in there unrelated other wrote all. if "project" means "an assignment class", or "the scripts use drive tivo", or "my progress in learning new language", creating repos per project seems bit unnecess...

i'm designing game object in f#. in c++, make classes represent graphical aspect, physical etc each dynamic values, , add instances of classes gameobject. use same design in f# mutable types, i'm trying keep immutable. if used same design recreating thousands of large objects each frame, , spend cpu time allocating. is there way can define type link object's values , supply new ones, cut down on allocations? eg change colour of box, want use old box's memory new graphics piece, , use old graphics piece's memory new colour: let box = ... ... let changedbox = {box graphics = { box.graphics colour = blue} } yes, exactly. assuming "the big object" in fact reference graph of many smaller objects, typical "update of immutable" creates 1 or 2 new small objects , references same old ones rest. for example, if person has name , address, , address has street , city , state , zip, , need update zip of person, need cr...

if i've got array of values zerofilled string representations of various numbers , array of integers, array_intersect() still match elements of different types? for example, work: $arrayone = array('0003', '0004', '0005'); $arraytwo = array(4, 5, 6); $intersect = array_intersect($arrayone, $arraytwo); // $intersect = "array(4, 5)" ... , if not, efficient way accomplish this? loop through , compare, or loop through , convert integers , run array_intersect() after, or ... $ cat > test.php <?php $arrayone = array('0003', '0004', '0005'); $arraytwo = array(4, 5, 6); $intersect = array_intersect($arrayone, $arraytwo); print_r($intersect ); ?> $ php test.php array ( ) $ so no, not. if add foreach($arrayone $key => $value) { $arrayone[$key] = intval($value); } you $ php test.php array ( [1] => 4 [2] => 5 )

it seems classical way handle transactions jdbc set auto-commit false. creates new transaction, , each call commit marks beginning next transactions. on multithreading app, understand common practice open new connection each thread. i writing rmi based multi-client server application, server seamlessly spawning 1 thread each new connection. handle transactions correctly should go , create new connection each of thread ? isn't cost of such architecture prohibitive? yes, in general need create new connection each thread. don't have control on how operating system timeslices execution of threads (notwithstanding defining own critical sections), inadvertently have multiple threads trying send data down 1 pipe. note same applies network communications. if had 2 threads trying share 1 socket http connection, instance. thread 1 makes request thread 2 makes request thread 1 reads bytes socket, unwittingly reading response thread 2's request if wrapped t...

is there way configure vim's gq function allows line breaking after hyphen (in compound word)? e.g. twentieth- century and way, i'm not on own laptop, on 1 of lab, runs windows, solution not using programs par or fmt bonus points :-) (though i'm interested in solutions using these tools if not possible using vim -- @ least able on laptop). thanks in advance. for ascii hyphen (0x2d), isn't possible. if you're able use unicode, can use identically-looking unicode variant (u+2010, cp. http://en.wikipedia.org/wiki/dash ) instead. can inserted via ctrl-v (ctrl-q on windows installations of vim), followed u2010 . or define digraph it: :digraph -- 8208 " hyphen, u+2010 with :set formatoptions+=m vim will also break @ multi-byte character above 255. voila! if need persist text ascii, write mappings / wrapper around gq :substitute s hyphens , forth.

i developing application using asp.net mvc platform, exposed service on web (the saas model). trying determine best way partition url namespace each user account. application need accessed securely via ssl, main concerns have been around coming url design works ssl certificates. here options have come with. in each example bob , jane 2 example user accounts: option a: each account has unique subdomain under common domain name e.g. https://bob.example.com https://jane.example.com this require wildcard ssl certificate (e.g. mapped *.example.com) each user can seamlessly access account via ssl. seamless mean without web browser warning user ssl certificate problems. drawback can think of wildcard certs seem considerably more expensive normal fixed domain certs. cost difference negligible in grand scheme of things, keeping in mind if else proves equal. option b: each account has unique domain name e.g. https://bobs-domain.com https://domain-of-jane.com in ca...
