in matlab, update data plotted in set of axes when user zooms plot window. example, suppose want plot particular function defined analytically. update plot window additional data when user zooms traces, can examine function arbitrary resolution. does matlab provide hooks update data when view changes? (or when redrawn?) yes, does. zoom mode object has following callbacks: buttondownfilter actionprecallback actionpostcallback the latter 2 executed either before or after zoom function. set update function in actionpostcallback , you'd update plot according new axes limits (the handle axes passed second input argument callback).

i have facebook 'like' application - virtual white board multiple 'teams' share 'wall' common project. there 9-12 entities capture data. i'm trying have user's homepage display update of activities have happened since past login - how facebook posts notifications: "[user] has done [some activity] on [some entity] - 20 minutes ago" where [...] clickable links , activities (rather only) crud. i'll have persist these updates. i'm using mysql backend db , thought of having update table per project store activities. seems there needs 1 trigger per table , redundant. more it's difficult nail down tabular schema update table since there many different entities. the constraint use mysql i'm open other options of "how" achieve functionality. any ideas? ps: using jquery + rest + restlet + glassfish + mysql + java it doesn't have handled @ database level. can have transaction logging service call in

i'm trying speed pagination of data on site. i'd use following query, when explain says needs scan on 40,000 rows: select `item`.`id`, `user`.`id` `items` `item` left join `users` `user` on (`item`.`submitter_id` = `user`.`id`) `item`.`made_popular` < "2010-02-08 22:05:05" , `item`.`removed` != 1 order `item`.`made_popular` desc limit 26 but if add lower bound "made_popular" field needs scan 99 rows (the number of items between 2 dates). select `item`.`id`, `user`.`id` `items` `item` left join `users` `user` on (`item`.`submitter_id` = `user`.`id`) `item`.`made_popular` < "2010-02-08 22:05:05" , `item`.`made_popular` > "2010-02-07 22:05:05" , `item`.`removed` != 1 order `item`.`made_popular` desc limit 26 both queries use index have on "made_popular" column. in both cases shouldn't need scan 26 rows, assuming there no "removed" items? guess solution go second que

this strange question, it's interesting thought i'd ask. let's don't how php's foreach loop operates , use in format, did added counter outside , used inside foreach loop tell if we're in last element. $counter = 1; $array_size = count($array); foreach($array $item){ //code if($counter == $array_size){ $islast = true } else { $islast = false; } $counter++; } my question is: can override or fork or inherit (or whatever want call that) original php foreach loop include new ability, can this, without need initializing counter , such. newforeach($array $item){ //code $islast = //something returns true/false; } it's interesting idea, wonder if 1 of hardcore php guys here can somehow make possible? or sort of modification way complicated without hacking language itself?! if question "can override implementation of php's language constructs" answer no. feature of other dynamic langauges javas

take @ method: [textbutton addtarget:self action:@selector(articlemodalwillappear:) forcontrolevents:uicontroleventtouchdown]; when button touched, calls articlemodalwillappear: . works well. problem button calls action when dragged. (the button big , contains text paragraph) i put 6 such buttons subviews of uiscrollview (with uipagecontrol). works when dragging uiscrollview horizontally. pops modal views when dragging vertically because when finger dragging across button, button considers touch, , touch calls articlemodalwillappear: . if still don't understand problem, think new york times ipad app. can drag pages horizontally. can touch article description go full article view. nothing happens when drag vertically inside article description. how achieve this? use different event e.g.: [textbutton addtarget:self action:@selector(articlemodalwillappear:) forcontrolevents:uicontroleventtouchupinside]; uicontroleventtouchupinside used in case.

the following flowchart: may described following java code: if (a == 1 && b ==1){ actiona(); } if (b == 3 || (b == 1 && == 2)){ actionb(); actionc(); } if (b == 2){ actionc(); } is there better way translate flowchart in java code? looking sort of general pattern this. question arises fact adding single condition flowchart results in significant changes code. you encapsulate actionb , actionc, while actionc being called after actionb in actionbc , make new method each cell in flow chart. in general should like: void b1(){ if(b==1) a1(); if (b==2) actionc(); ... } void a1(){ if(a1==2) actionbc(); } private void actionbc(){...} and on... in way, expanding flowchart won't explode code.

i need combinations of array. example: array ( array("a","b"), array("1","2","3","4") ); and need array ( array("a","1"), array("a","2"), array("a","3"), array("a","4"), array("b","1"), array("b","2"), array("b","3"), array("b","4"), ); of course must work when sizeof($array) >= 2. thanks much

i have weighted, directed graph multiples edges starting ending @ same nodes. ex. multiple edges going node node b. what best search algorithm of paths node , associated costs of these paths? since want paths, i'd use simple breadth-first search. however, suggest collapse parallel edges single edge has list of weights. once different paths (that is, paths in nodes visited different), each path can calculate possible alternative parallel routes. so if you've got following edges: a -> c (5) -> c (3) -> b (7) b -> c (1) b -> c (4) the first step transforms into: a -> c (5,3) -> b (7) b -> c (1,4) the breadth-first search on graph yield following paths between , b: a -> b (7) -> c -> b (5,3) + (1,4) so second path, you'll following costs: 5 + 1 5 + 4 3 + 1 3 + 4 this isn't going faster in doing bfs on original graph, simpler graph easier handle.

i wondering if compiler specific problem or not. i've seen examples of use of constructors struct in c++. i have like: struct example { example() { } }; i still compiler error "functions may not part of struct or union". using old borland 4.5 compiler (best not ask why...). (and yes, done in c++). i can't myself: why? using compiler announces it's support windows 95 sort of interesting. c++ standard 1998, published before perhaps not date? :-) other that, code ok.

what performance counter , how use them in asp.net application. please explain. from msdn : counters used provide information how operating system or application, service, or driver performing. counter data can determine system bottlenecks , fine-tune system , application performance. operating system, network, , devices provide counter data application can consume provide users graphical view of how system performing. the .net framework has several classes allow use , create performance counters, main ones performancecounter , performancecountercategory , countercreationdata (for creating new counters). from documentation on system.diagnostics namespace: the performancecounter class enables monitor system performance, while performancecountercategory class provides way create new custom counters , categories. can write local custom counters , read both local , remote counters (system custom). can sample counters using performancecounter class, , calcul

why os.path.relpath , on windows, not returning proper relative path when using drive start point, either explicit or implied (current directory) >>> os.getcwd() 'u:\\projects' >>> os.path.relpath(r'd:\foo\something', r"d:\\") '..\\foo\\something' >>> os.chdir("d:\\") >>> os.getcwd() 'd:\\' >>> os.path.relpath(r'd:\foo\something') '..\\foo\\something' >>> os.path.relpath(r'd:\foo\something', r"d:\\foo") 'something' i expecting see 'foo\\something' or '.\\foo\\something' does have os.path.join note on windows? note on windows, since there current directory each drive, os.path.join("c:", "foo") represents path relative current directory on drive i using python 2.7 issue fixed under python 2.7.1 issue #5117: fixed root directory related issue on posixpath.

this question has answer here: finding property differences between 2 c# objects 6 answers what best way compare 2 objects , find differences? customer = new customer(); customer b = new customer(); one flexible solution: use reflection enumerate through of properties , determine , not equal, return list of properties , both differing values. here's example of code start asking. looks @ field values right now, add number of other components check through reflection. it's implemented using extension method of objects use it. to use somecustomclass = new somecustomclass(); somecustomclass b = new somecustomclass(); a.x = 100; list<variance> rt = a.detailedcompare(b); my sample class compare against class somecustomclass { public int x = 12; public int y = 13; } and meat , potatoes static

if have find let's word in sentence, can think of 2 approaches using string.indexof using regex which 1 better in terms of performance or best practice it depends on exact requirements. if need find word in sentence (not substring), believe expressed more concisely , more explicitly using well-named regex pattern using indexof plus logic make sure you're getting complete single word. on other hand, if you're looking substring, indexof far superior in terms of performance , readability.

ok, preface question potentially 'stupider' normal level of question - problem has been annoying me last few days i'll ask anyway. i'll give mock example of problem can hope generalize current problem. #!/usr/bin/perl -w use strict; use test::more 'no_plan'; $fruit_string = 'apples cost $1.50'; ($fruit, $price) = $fruit_string =~ /(\w+)s cost \$(\d+\.\d+)/; # $price += 0; # uncomment great success ($price, 1.50, 'great success'); now when run message # failed test 'great success' # got: '1.50' # expected: '1.5' to make test work - either uncomment commented line, or use is ($price, '1.50', 'great success') . both options not work me - i'm testing huge amount of nested data using test::deep , cmp_deeply. question is, how can extract double regexp use double - or if there better way altogether let me know - , feel free tell me take gardening or lol, learning perl hard.

i'm embarking on first foray mobile site design - i've set method redirect mobile users separate url, need design mobile version of site (targeting smart phones android / iphone). dimensions should create to? there way force mobile browsers scale content down? (currently site appears big within mobile window , must scroll horizontally , vertically see all). 320 x 480 pixels standard mobile sites. things absolutely must know footers mobile. iphone has bastard of browsers , no emulator emultates correctly - specifically: css footer style - position:fixed; bottom:0; don't try it. iphone recognizes position:relative; iphones not recoginized position style of fixed - in case want footer stay on teh bottom.

i adding 5th table existing join. original query return single row because clause specifies unique id. here tables using: table 1 carid, catid, makeid, modelid, caryear table 2 makeid, makename table 3 modelid, modelname table 4 catid, catname table 5 id, caryear, makename, modelname here existing query using: select a.*, e.citympg, e.hwympg table1 join table2 b on a.makeid=b.makeid join table3 c on a.modelid=c.modelid join table4 d on a.catid=d.catid join table5 e on b.makename = e.make , c.modelname = e.model , a.caryear = e.year a.carid = $carid; there 2 issues need solve - when there no match on table 5, not return results. seem need sort of left join or split query , union. when there match on table 5, returns multiple rows. since criteria return single row not being used, settle average of citympg , hwympg. can both objectives achieved single query? how? assuming understand want correctly... query c

hi have page http://samarjit.net78.net/jquerybrowser/jquery.apitest.snapshot.xml has large amount of data. hmtl generated xslt transformation browser. when click on left menu shows filtered contents in center. same filtering can done using right side search box. same method same parameters called on click of go button left menu. now when refresh page , couple of times filtering using left menu works pretty fast. once filter using textbox , press go takes longer filter. subsequent filtering left menu appears slow. if not use search box once keep on clicking main menu not slow down. this quite strange , experienced in firefox 3.6.8 firebug, firequery, pixelperfect, , firefinder . tested without opening firebug. in ie8 , chrome runs faster firefox in general , slow down never happens. can test @ end , tell me if behavior visible?
