i'd able test guesses memory complexity of various command line utilities. taking simple example grep pattern file i'd see how memory usage varies size of pattern , size of file . for time complexity, i'd make guess, run time grep pattern file on various sized inputs see if guess seems borne out in reality, don't know how memory. one possibility wrapper script initiates job , samples memory usage periodically, seems inelegant , unlikely give real high watermark. i've seen time -v suggested, don't have flag available on machine (running bash on osx) , don't know find version supports it. i've seen on linux information available through proc filesystem, again, it's not available me in context. i'm wondering if dtrace might appropriate tool, again concerned simple sample-based figure might not true high watermark? does know of tool or approach appropriate on osx? edit i removed 2 mentions of disk usage , asides , p

the problem find nth element in linked list, have problem figured out on finding element. but have read input file , output nth element list for example input b c d 4 e f g h 2 output g it stated "the first argument path filename containing series of space delimited characters followed integer representing index list (1 based), 1 per line" i not sure how go this? first read file , store each line in list? yes, should read file line line, , store each line in list<string> . then, this: string line; // use iterator on list each line string[] elements = line.trim().split("\\s"); char[] chars = new char[elements.length - 1]; int index = integer.parseint(elements[elements.length - 1]); (i = 0; < elements.length - 1; i++) char[i] = elements[i].charat(0); now have characters in array ... , said have rest figured out.

say example blog permalink structure (year/month/title) http://blog.example.com/2012/04/my-title and posts permalinks are: http://blog.example.com/my-title to make sure google search results don't break want add .htaccess redirect. using yoast permalink redirector generator on website suggests adding: redirectmatch 301 ^/([0-9]{4})/([0-9]{2})/([^/]+)/$ http://blog.example.com/ $3 at first glance works great. wordpress has attachment urls such as: http://blog.example.com/2012/04/my-title/my-attachment-url/ that link should redirected to: http://blog.example.com/my-title/my-attachment-url/ but it's not when using yoast redirect. thoughts on how update .htaccess regex catch attachment urls well? i'll keep googling in mean time. can post on wp stack overflow tends better answers server regex htaccess questions. i think regex right. need escape slashes backslash: ^\/([0-9]{4})\/([0-9]{2})\/([^/]+)\/$ actually capture attachment urls surround

as know asynctask works background thread , returns control gui when task complete , requests through volley can made in main activity thread , lets assign json response string variable upon completion of request , string null , program further processes reponse, problem got was thrown nullpointerexception while processing response string after successful response , absurd possible if response slow program may continue without initializing string variable ?? it sounds not using proper callback on data. in other words, after start asynctask, have wait until done until reference global variables might impact. so, if didn't write proper callback method, yes program continue. idea behind asynctask - let thread called on continue while long process of kind.

i looking rename subdirectories names begin rr , don't have subdirectories of own 'a' in bash , if glob wildcard doesn't match print wildcard character itself, e.g. if /somedir/ not have subdirectories, after expansion /somedir/*/ literary equivalent '/somedir/*/' . so simple bash script find directories without subdirectories , names beginning rr be #!/bin/bash shopt -u nullglob while read -r dir; [[ $(echo "$dir"/*/) == "$dir/*/" && ${dir##*/} =~ ^'rr' ]] && echo "$dir" done < <(find . -type d) should easy interpolate there, not clear want when have multiple directories matching criteria , can't rename them a ? to rename directories rretcetc a , change following #!/bin/bash shopt -u nullglob while read -r dir; [[ $(echo "$dir"/*/) == "$dir/*/" && ${dir##*/} =~ ^'rr' ]] && mv -v "$dir" "${dir%/*}/a"

we have app model object can pass through various states in progressive fashion - think of order progressing sale, example. each state of order handled different view controller. each view controller recognizes state(s) can handle, , when state has been reached cannot handle, pushes subsequent view controller handle next state. various events can cause vc update view; method setupviewbyorderstate called @ point. same method called in viewdidappear . for example, order can pass through states 1-10. viewcontroller handles states 1-2, b handles 3-5, , c handles 6-10. if handed order in state 1 or 2, configures itself. if handed order in state 3 or greater, pushes b, , hands off order. etc. one advantage of technique first vc 'entry point' - hand given order , push necessary vcs until 1 reached can handle order in current state, without logic explicitly coding state->vc correspondences ever needing exist outside each vc. a problem arises, though, should 1 wis

i trying load audios dynamically in project. i've used jplayer, mediaelement.js , javascript create audio element. working fine in desktop browser fails in android(os 4.1+) browsers except firefox. i've attached codes of various player tried. jplayer: $("#jquery_jplayer_1").jplayer({ ready: function (event) { $(this).jplayer("setmedia", { mp3: "sample.mp3", oga: "sample.ogg" }).jplayer("play"); }, swfpath: "js", supplied: "mp3, oga", wmode: "window", smoothplaybar: true, keyenabled: true, ended : function(){ //$(this).jplayer("stop" ); //$(this).jplayer("playhead",100); if(pcnt != tocarr.length-1){ $("#nextins").css("display","block"); } } }); mediaelement.js: audioplayer = new mediaelementplayer("

in java code directly accessed member variables. want refactor , use getter , setters. how can make eclipse automatically replace direct assignments setters , each access getter? right click -> source -> generate getters , setters creates functions not apply them in rest of code. use refactor menu. has item "encapsulate fields" generates getters , setters "source -> generate getters , setters" does, in addition replaces usages of fields , makes fields private. (as mnemonic: change structure of existing code (i.e. refactor it), use refactor menu. generate new code not used yet, use source menu. is, if create new class getters , setters, can use of source menu coding fields , auto-generate getters , setters afterwards. if want existing code use getters , setters instead of direct field access, classic case of code refactor ing.)

e.g. function sq(x) x ^ 2 end function sq2(x) (x+1) ^ 2 end function fun(x) sq(x) end i replace sq call sq2 call redefine fun generic function. attempt below changes call wasn't able redefine function. appreciated. change(:fun, (int,)) function analyze_expr(exp::expr) = 1:length(exp.args) arg = exp.args[i] if(typeof(arg) == expr) analyze_expr(arg) elseif(arg==symbol("sq")) exp.args[i] = symbol("sq2") end end end function change(sym::symbol, params) func = eval(sym) func_code = code_lowered(func, params) func_body = func_code[1].args[3] analyze_expr(func_body) println("printing function body:",func_body) end i suspect you'll find easier kind of work using macros: http://docs.julialang.org/en/latest/manual/metaprogramming/ given existing function definition, relevant thing in julia isn't syntax generated compiled machine code resulted.
