i wonder sort of things when start working on existing, new you, system? let's system quite big (whatever means you). some of things identified are: where particular subroutine or procedure invoked? what arguments, results , predicates of particular function? how flow of control reach particular location? where particular variable set, used or queried? where particular variable declared? where particular data object accessed, i.e. created, read, updated or deleted? what inputs , outputs of particular module? but if more specific or of above questions particularly important please share :) i'm particularly interested in extracted in dynamic analysis/execution. i use "use case" approach: first, ask myself "what's software's purpose?": try identify how users going interact application; once have "use case", try understand objects more involved , how interact other objects. once did this, draw uml-type diagra

hi, consider these method calls 1) audiofileopenurl(infileurl,kaudiofilereadpermission,kaudiofilemp3type,fileid) 2) audiofileopenurl(infileurl,kaudiofilereadpermission,kaudiofilemp3type,&fileid) the second call has "&" symbol before fileid parameter. "&" mean? that's not objective-c feature. it's c "address of" operator. gives memory address of variable opposed contents.

if user clicks browser's button, want prompt appear , ask confirmation. if user clicks 'ok', should navigate xx.html . if user clicks 'cancel', should prevent navigation. how can this? note: tried onbeforeunload method, working navigation actions. example, clicking link on page fire event , show message user. you can't. best can use onbeforeunload , remove event when clicking on normal link: <script type="text/javascript"> window.onbeforeunload = function() {return "are sure?"} </script> <a href="somewhere.html" onclick="window.onbeforeunload = null;">leave</a>

i'm trying setup xerces can use in qt creator windows. does qt support windows/linux binaries or have compile using mingw target? how 1 goes compiling libraries in windows? no, can't use libraries compiled linux under windows. you'll have either build or use existing windows binary distribution. how works in detail depends on third-party library want use. basic options are, in case have build yourself: build msvc under windows, mingw under windows, or cross-compile mingw e.g. linux. msvc tends less hassle under windows, mingw might work well. important : mingw , msvc abi-incompatible when comes c++ libraries. can't use e.g. msvc-built xerces in mingw-qt project, or mingw-xerces in msvc project. affects c++ libraries, not pure c ones.

consider: std::vector<int> v; v.reserve(1); v.push_back(1); // statement guaranteed not throw? i've chosen int because has no constructors throw - if copy constructor of t throws, exception escapes vector<t>::push_back . this question applies insert push_back , inspired is safe push_back 'dynamically allocated object' vector? , happens ask push_back . in c++03 , c++0x standard/fcd, descriptions of vector::insert if no reallocation happens, iterators/references before insertion point remain valid. don't if no reallocation happens, no exception thrown (unless constructors etc of t). is there elsewhere in standard guarantee this? i don't expect push_back throw in case. gnu implementation doesn't. question whether standard forbids it. as follow-up, can think of reason why implementation throw? best can think of, if call reserve ends increasing capacity value in excess of max_size() , insert perhaps permitted throw length_error w

rookie question: i have been experiencing minor bug in mvc2 application. able trace code: list<stream2fieldtypes> stream2fieldtypes = new list<stream2fieldtypes>(); foreach (var item in stream.stream2fieldtypes) { stream2fieldtypes.add(item); } the problem experiencing when instatiate new list, has count of one. i'm thinking due using constructor. tried this: list<stream2fieldtypes> stream2fieldtypes; foreach (var item in stream.stream2fieldtypes) { stream2fieldtypes.add(item); } but, of course not compile because of error on stream2fieldtypes.add(item); . there way can create list<stream2fieldtypes> , make sure count zero? the problem experiencing when instatiate new list, has length of one no, that's totally impossible. problem somewhere else , unrelated number of elements of newly instantiated list. list<stream2fieldtypes> stream2fieldtypes = new list<stream2fieldtypes>(); stream2fieldtypes.cou

possible duplicate: how fix perl code 1.1 + 2.2 == 3.3? i'm working on perl script compares strings representing gene models , prints out summary of comparison. if gene models match perfectly, print out terse summary, if different, summary quite verbose. the script looks @ value of variable determine whether should terse or verbose summary--if variable equal 1, should print terse summary; otherwise, should print verbose summary. since value numeric (a float), i've been using == operator comparison. if($stats->{overall_simple_matching_coefficient} == 1) { print "gene structures match perfectly!\n"; } this worked correctly of tests , of new cases running now, found weird case value equal 1 above comparison failed. have not been able figure out why comparison failed, , stranger yet, when changed == operator eq operator, seemed work fine. i thought == numerical comparison , eq string comparison. missing here? update: if print out val

i came across interesting problem today. altering stored procedure , put select statement @ end. meant temporary , working data. surprised find out later statement got saved , executing whenever sp ran. set ansi_nulls on go -- comments go here , saved part of sp alter procedure [dbo].[mysp] @param int begin --your normal sql statements here end --you can add sql statements here select * largetable --you have access params select @param it makes sense saved, not inside begin/end, otherwise comments , set ansi_nulls , etc. disappear. i'm little confused starts where, have few questions: set ansi_nulls gets saved part of sp. have confirmed each sp has own value. how sql server know save part of sp since it's not referenced before? full scan of current environment state, when alter procedure runs saves state (possibly non-default values)? apparently begin/end optional , have no intrinsic meaning. why included then? give false sense of scope doesn

i want add library wrote rails app (and other rails apps later). tried putting in /lib seemed logical... [rails_root]/lib/my_lib/the_main_file.rb [rails_root]/lib/my_lib/some_other_file.rb then... require 'my_lib/the_main_file' that works fine. but great way it? now have put require everywhere want call library. i thought putting require in initializer seems kind of weird. what people this? using initializer may weird when have single file include, have many files want add, , end using intializer includes stuff. it's pretty neat.

suppose have 2 entity types: user , country. country entities never created , aren't mutable. they're keyed iso alpha3 country codes, e.g. "usa". reside in table country pk column id. users have many-to-one mapping country w/ cascade = none. users reside in user table fk column country_id references country(id). when creating new user might like: user user = new user(); user.setcountry(em.find(country.class, "usa")); em.persist(user); i gather that's wasteful, though, since requires query against country first. noticed can this: country usa = new country(); usa.setid("usa"); user user = new user(); user.setcountry(usa); em.persist(user); since cascade = "none" shouldn't need query country table; should insert "usa" directly user country_id. correct? now suppose there's code ever creates users country_id = "usa". in case, occurred me store static instance of country id = "usa&

how make sure have releasable build? i'm on scrum team running following problem: @ end of sprint, team presents finished user stories product owner. po typically accept several user stories reject 1 or two. @ point, team no longer has releasable build because build consists of both releasable stories , unreleasable stories , there no simple way tear out unreleasable stories. in addition, not want delete code associated unreleasable stories because typically need add few bug fixes. how should solve problem? guess there way branch build in such way either (a) each user story on own branch , user story branches can merged or (b) there way of annotating code associated each user story , creating build has working user story. don't know how either (a) or (b). i'm open possibility there easier solutions. i want stress problem not build broken. build not broken -- there user stories in build cannot released. we using svn willing switch source control system if

i working on test application on android platform. test write/read speed sdcard. write in c language ndk interface. first write for-loop create 256 files 512 random bytes in each. part works fine. open file flag o_creat|o_wronly|o_sync , mode 0666. after call write, sync() make sure data written on card. then write 2-level for-loop read these file test speed. use o_rdwr|o_sync open file. call read(). here thing: if first time run read part. first loop read take more time after. i'm sure because after first loop, program read cache not real physical card. i've tried o_direct flag read. error einval. in man page open, says maybe because of function not implement platform. do have idea on how read no-cache in android? you may need rooted phone disable operating-system-level caching. http://wiki.cyanogenmod.com/index.php?title=sdcardspeedtests that takes care operations large enough overwhelm on-card buffers.

there 20 buttons in activity . the ids r.id.buttonr1c1; r.id.buttonr1c2 .. , on ie. row 1, col 1.. now earlier had created 20 buttons. private button b1,b2,b3...; and b1=(button)findviewbyid(r.id.buttonr1c1); b2=(button)findviewbyid(r.id.buttonr1c2); .... , on. finally b1.setonclicklistener(this); b2.setonclicklistener(this); ... 20 so thought i'd create button array button barray[][]=new button{4][5]; for(int i=1;i<=4;i++) { (int j=1;j<=5;j++) { string t="r.id.buttonr"+i+"c"+j; barray[i-1][j-1]=(button)findviewbyid(integer.parseint(t)); } } gives error.. any help?? if have copied code directly, syntax wrong. button barray[][]=new button{4][5]; should be button barray[][]=new button[4][5]; note curly bracket instead of square bracket before 4. your next problem, trying value of r.id.something, have string representation of it. so, way know using reflection. what need is, button barra

i have hosted application in machine running red hat enterprise linux 5. started jboss using command. ./run.sh -b 0.0.0.0 and ./run.sh -djboss.bind.address=<<server_address>> and ./run.sh --host=<<ipaddress>> but using of these commands cannot access application remotely. using the above commands cannot access application on host machine itself, using localhost ip address. not able figure out problem here. can ping linux machine other windows machines. check iptables rules not blocking firstly also running user? if so, not have permission bind port number less 1024. try telneting port server check service responding e.g. telnet localhost 8080 presuming running on 8080 in example above. you can drop iptables temporarily testing if safe by: /etc/init.d/iptables stop and restart them when you've finished with /etc/init.d/iptables start you can make permanent change iptables config adding following line /etc/sysconfig/i
