is there software/profiling tool given algorithm , set of inputs gives efficiency of algorithm in terms of o-notation big-o describes how running time (and memory space) of algorighm scales inputs of different sizes, such tool have not accept particular input. if can generate range of inputs on range of sizes, feed each input algorithm, measure execution time (and/or memory size), , plot result, can compare against various possible big-o curves. i don't know of such general symbolic algorithm, , sounds bit of ai problem. writing 1 exercise. there algorithms not analyze, might able analyze useful subset.

i new json document,i hava database following fileds: on basis of database field have created json document: ================================================================ {"id":["fifth","first","four","second","thrid"],"keyword":["michel","sam","jerry","john","smith"]} ================================================================ i want know prepared json document correct elastic search or not? if wrong correct document that. thanks i dont think good. should create json in following format. var data = { "fifth" : "michel", "first" : "sam", "four" : "jerry", "second" : "john", "thrid" : "smith" } so when need fourth element, can following var fourth = data["four"]; hope helps!

i want create custom cell in jtable. used custom renderer , returned jpanel object. works there 1 problem. while program running jpanel draws on using paintcomponent() method. on each "tick" (usually each 100ms) panel getting wider (i m drawing kind of graph) , when becomes big rest hidden. i d resize , create scrollbar. tried several ways of putting scrollpane none of them worked. basically, want thread view in java visualvm. ideas? it hard work put scroll pane inside ordinary table cell, because 1 component used render cells in table. may remove jtable , put large set of components in ordinary jpanel grid layout? if still want use jtable: every scroll pane contain special jviewport control. jviewport control scrolling work, , jsrollpane layout scroll bars. because single viewport used cells, must store somewhere viewport scroll position , restore every painting cell (on getcellrenderer method). jsrollpane need heavy layout work slow solution. may prefera

in .net there null reference, used everywhere denote object reference empty, , there dbnull , used database drivers (and few others) denote... pretty same thing. naturally, creates lot of confusion , conversion routines have churned out, etc. so why did original .net authors decide make this? me makes no sense. documentation makes no sense either: the dbnull class represents nonexistent value. in database, example, column in row of table might not contain data whatsoever. is, column considered not exist @ instead of merely not having value. dbnull object represents nonexistent column. additionally, com interop uses dbnull class distinguish between vt_null variant, indicates nonexistent value, , vt_empty variant, indicates unspecified value. what's crap "column not existing"? column exists, doesn't have value particular row. if didn't exist, i'd exception trying access specific cell, not dbnull ! can understand need differentiate between vt_null

i have table this: <table> <tr class="a"><td></td></tr> <tr class="b"><td></td></tr> </table> there 800 rows , of them of class a. want toggle these rows this: $("#toggle_a").click(function(){ $("tr.a").toggle(); }); $("#toggle_b").click(function(){ $("tr.b").toggle(); }); but extremely slow , of time browser wants stop action. has idea how make thing faster , usable? seems because jquery searching element class name.. note: class selector among slowest selectors in jquery; in ie loops through entire dom. avoid using whenever possible. also check this article

i have noticed when sending packets @ intervals udp socket, first packet sent seems delayed. example, if sending packets every 100 ms, find delay between receiving packets distributed mean 100ms , average standard deviation of 4, on network. however, gap between receive time first , second packets around 10 40 ms - can see, that's statistically significant difference, , question is, what's causing it? i'm using sendto function c on linux. suggested delay might caused arp resolution preventing packet being sent until destination ip has been converted mac address - likely? if restart sending program first packet again takes long though, , delay inconsistent - 10 40 ms pretty big range. i need find out why first packet taking long, , how work around it. edit: further analysis pcap indicates sending program sending packets @ right interval. problem must receiver, using select() wait readable socket, calling recvfrom , printing packet. there sort of buffering going on

i have files, 1 full of keywords sequences (~20k lines), other full of regular expression (~2.5k). i want test each keyword each regexp , print 1 matches. tested files , makes around 22 750 000 tests. using following code : $count = 0; $countm = 0; foreach ($arrayregexp $r) { foreach ($arraykeywords $k) { $count++; if (preg_match($r, $k, $match) { $countm++; echo $k.' matched keywords '.$match[1].'<br/>'; } } } echo "$count tests $countm matches."; unfortunately, after computing while, parts of actual matches displayed , final line keeping counts never displays. more weird if comment preg section keep 2 foreach , count display, works fine. i believe due excessive amount of data processed know if there recommendations didn't follow kind of operations. regular expressions use complicated , cannot change else. ideas anyone? increase execution time usethis line in .htaccess

i wish users of java chat applet automatically logged out when closing browser window. i use following: public void destroy() { sendlogoutmessage(); } however works 3/4 of time (probably due network delays). the chat applet pings server , logs them out after 90 seconds (this allows them reconnect due internet problems) - removed eventually, way better catch close event. i think code not work in 100% cases because called in destroy method not wait , closes including network connections being opened. so, if network slow applet output streams killed before sends logout message server. if theory correct can check it. try see whether logout command in server logs (in case of failure). believe find command did not arrive. open java console on client side. ioexception or socketexception. hope examining of exception may give idea how improve solution. additionally i'd suggest following. add servlet session listener on server side , logout automatically

i found code shows map , calculate travel time driving. possible find travel time using transit (e.g. bus) ? code found using google.maps.directionstravelmode.driving , looked api , driving, bicycling , walking available. thanks in advance! unfortunately, google maps supports static route computation. when talk satic means system considers route , average speeds, fixed, determine travel time. taking buses account require comprehensive knowledge of bus lines, stops , timetables. it's not impossible do, hard. example, estimated bus travel time must take account waiting time next bus @ stop, , must have knowledge of timetables too! (not lines , speeds). the same applies merging bus , underground (where available). i hope believe that, in future, google maps able provide these information too.

i have sql server 2005 database want setup replication for. problem database has 2 schemas both of have table same name in it. for reason though tables in different schemas replication creation fails when done through management studio due conflicting article names (i assume trying create same name both tables in different schemas). is there workaround doing in studio, can write script or program 1 thign bit annoying , wont allowed run in production. perhaps there hot fix or i'm not aware about? cheers, there doesn't appear way around purely using new publication wizard in ssms - article name table name without schema-qualifier, , can't customised wizard - although there work-around if use scripting options. go through wizard normal, @ end of process, untick "create publication" option , select "generate script file..." option. once file created, open , edit article names no longer conflict, execute script in publication database

with groovy ast transformations , how can figure out return type of methodcallexpression ? methodcallexpression.gettype() returns java.lang.object if explicitly define return type of method in method definition. due dynamic nature of groovy, ast can't know return type of method call expression @ compile time. example: class example { string foo() { "foo" } } def e = new example() assert e.foo() == "foo" looks simple enough. foo returns string, methodcallexpression e.foo() should have type of string , right? if foo changed in metaclass? class example { string foo() { "foo" } } def e = new example() if (someruntimecondition) { e.metaclass.foo = { -> 42 } } assert e.foo() == "foo" // foo string or int? the groovy compiler doesn't have enough information make assumptions method call since change @ runtime, has compile down object.

soooo....long time reader first time poster. first time, can't find answer! i've got model returns array of results (working). loop through results foreach , append array additional values second function in model. problem first of several function calls return results. function get_offering_total() returns value first listed call (cash). returning correct value, subsequent attempts use same function returns nothing. var_dump shows array structured correctly on output, values null. there issue calling same model method different parameters? needs cleared/reset? here's code... //$data['offerings'] stores results first query foreach( $data['offerings'] $key => $value ) { //set filters $cash_filter = array( 'method' => '5' ); $checks_filter = array( 'method' => '6' ); //get totals $data['offerings'][$key]['cash'] = $this->model_records->get_offering_total( $value['offer

i have window button triggers lengthy processing. put processing in separate thread, -- surprise -- makes gui frozen anyway. no control refreshed, cannot move window. so the question how start thread, won't interfere gui, i.e. gui date (while processing change data, , gui displays pieces of it)? that how start thread currectly: var thread = new thread(dolearn); thread.isbackground = true; thread.start(); edit 1 jon: i don't use locks @ all no join calling the ui thread left alone -- sits there the processing big loop math operations, not allocating memory, on ui side have controls binding (wpf) data, number of current iteration of main loop. should refreshed each time main loop "ticks". counter of loop property triggers onpropertychanged each change (classic wpf binding). edit 2 -- there! ok, jon hit nail @ head (who surprises? ;-d) -- thank you! problem comes changing counter. when used instead counter, local counter

i have .pem certificate ssl, want distribute web application in msi (has run on clients' computers). need import (into credentials store?) , tell site bindings use it. how can in code? i've discovered microsoft.web.administration, not sure go there … this in iis7 btw. edit: goal here have web application customers can run on intranets. acts api iphone app. (maybe isn't best design we're locked in now.) customer installs msi, , voila, have web service. there needs password authentication between iphone , web service; simplest way seemed to in https. made self-signed cert. i'm aware redistributing single cert bad idea, we're trying defeat casual hackers here … going intranet , businesses only, seems unlikely going doing crazy, , api severely restricts amount of bad things able database anyways. so there go, goal have password authentication on intranet web app, one-click(ish) installation. :-d the answer, dear readers, this: // assume '

is possible create/delete different databases in graph database neo4j in mysql? or, @ least, how delete nodes , relationships of existing graph clean setup tests, e.g., using shell commands similar rmrel or rm ? you can remove entire graph directory rm -rf , because neo4j not storing outside that: rm -rf data/* also, can of course iterate through nodes , delete relationships , nodes themselves, might costly testing ...

is there clean way run parameterized junit 4 tests without changing runner, i.e. without using @runwith(parameterized.class) ? i have unit tests require special runner , can't replace 1 parameterized . maybe there kind of "runner chaining" both runners @ same time? (just wild guess...) org.junit.runners.parameterized created org.junit.internal.builders.annotatedbuilder reflect mechanism. maybe extend parameterized own runner: @runwith( myparameterized .class).

actually queried optimize table query 1 table. didn't operation on table. again i'm querying optimize table query @ end of every month. data in table may changed once in 4 or 8 months. create problem in performance of mysql query? if don't dml operations on table, optimize table useless. optimize table cleans table of deleted records, sorts index pages (brings physical order of pages in consistence logical one) , recalculates statistics. for duration of command, table unavailable both reading , writing, , command may take long large tables.

using linq sort passed in int arrays index. so in code below attribueids int array. i'm using integers in array clause results in order in while in array. public list buildtable(int[] attributeids) { using (var dc = new mydc()) { var ordering = attributeids.tolist(); var query = att in dc.dc.ecs_tblattributes attributeids.contains(att.id) orderby(ordering.indexof(att.id)) select new common.models.attribute { attributeid = att.id, displayname = att.displayname, attributename = att.name }; return query.tolist(); } } i recommend selecting attributeids array instead. ensure items correctly ordered without requiring sort. the code should go this: var query = id in attributeids let att = dc.dc.ecs_tblattributes.firstordefault(a => a.id == id) att != null s

i wish create follow style button on view in mvc not sure whether should using htmlhelper or not. button need show different text depending upon whether or not user following item , call different script when clicked if user deciding follow or unfollow. should helper create button entirely or contents of button? mvc purists argue decision on whether user can follow item should made in controller , passed in model. boolean value passed htmlhelper. public static string followbutton(this htmlhelper source, bool isfollowing) { if (isfollowing) { return "<button>unfollow</button> //unfollow button } else { return "<button>follow</button> //follow button } } then on view <%= html.followbutton(model.isuserfollowing) %> and following standards, javascript should created separately. use class="follow" on follow button means javascript identify script should used.

i'm trying find fastest way complete preprocessed source code (i don't need #line information other comments, raw source code) c source file. i have following little test program includes windows header file ( mini.c ): #include <windows.h> using microsoft visual studio 2005, run command: cl /nologo /p mini.c this takes 6 seconds generate 2.5mb mini.i file; changing to cl /nologo /ep mini.c > mini.i (which skips comments , #line information) needs 0.5 seconds write 2.1mb of output. is aware of techniques improving further, without using precompiled headers ? the reason i'm asking wrote variant of popular ccache tool msvc. part of work, program needs compute hash sum of preprocessed source code (and few other things). i'd make fast possible. maybe there dedicated preprocessor binary available, or other command line switches might help? update: 1 idea came mind: define win32_lean_and_mean macro strip out lots of needed code. speeds ab
