is there situation in notify() can cause deadlock, notifyall() - never? for example, in case of multiple locks. notify() notifies 1 thread run, checks lock object , becomes waiting again, though thread unlock object. in case of using notifyall() , threads notified run , 1 of them in turn unlock object sure. yes. imagine implement producer - consumer problem synchronize, wait, , notify . (edit) in 2 producers , 2 consumers wait on same object monitor (end edit) .the producer calls notify in implementation. suppose have 2 threads running producer's code path. possible producer1 calls notify , wakes producer2. producer2 realizes can not work , subsequently fails call notify . deadlocked. (edit) had notifyall been called, both consumer1 , consumer2 have woken in addition producer2. 1 of consumers have consumed data , in turn called notifyall wake @ least 1 producer, allowing broken implementation limp along successfully. here reference question base scenario...

i using qt 5.1.0 bundled mingw 4.8 (32 bit) on win7 64. i want run lupdate.exe create , update translation files. however, every run of lupdate demands administrator access rights , windows uac prompt need accept. annoying. issue arises @ lupdate. lrelease other qt tools run expected. not sure whether relevant: lupdate.exe installed in default path, c:\qt\5.1.0\mingw48_32\bin\lupdate.exe. i not see reason why lupdate needs admin rights , not case in former versions. so, why installation prompt them? how can avoid it? this because windows checks file name , assumes containing "update", "install", or "uninstall" in file name installer, , requires administrative privileges run, regardless of whether has manifest or not. done old legacy installers created before uac existed continue work. rename "lupdate.exe" doesn't contain "update", , uac prompts stop.

i'm using nganimate animate max-height simple slide-toggle effect, , there's bit strange happening: when hiding , seems setting transition property on setup class ( .xxx-hide ) doesn't work--the height snaps 0 immediately: .controls-hide { -webkit-transition-duration: 1s; -moz-transition-duration: 1s; -o-transition-duration: 1s; transition-duration: 1s; max-height: 5em; opacity: 1; } .controls-hide.controls-hide-active { max-height: 0em; opacity: 0; } but setting on active class ( .xxx-hide.xxx-hide-active ), animation works fine: .othercontrols-hide { opacity: 1; max-height: 5em; } .othercontrols-hide.othercontrols-hide-active { -webkit-transition-duration: 1s; -moz-transition-duration: 1s; -o-transition-duration: 1s; transition-duration: 1s; max-height: 0em; opacity: 0; } (here's whole fiddle. ) even more strangely, opacity animates fine in both cases. what's going on here? i follow instructions @ site: h...

looking @ legacy code , programmer in question uses: <cfthread action="run"> <cfexecute name="c:\myapp.exe" timeout="30"> </cfthread> can 1 safely replace code above this? <cfexecute name="c:\myapp.exe" timeout="0"> is cf going spawn thread in code above anyway? , thread going counted towards "maximum number of threads available cfthread"? if intent have non-blocking flow of code, can safely replace earlier code yours. in understanding, cf not creating thread when gets timeout="0". must calling exe (which creates new process on server) , never wait process reply. so, nothing added thread limit count.

i'm adding exception handling jqm app , i'm having trouble page transitions. in nutshell, i'm doing this: window.onerror = function myerrorhandler(errormsg, url, linenumber) { // crap, bad happened somewhere. // tell user // report testflight // @ variables in memory , try determine how gracefully recover. } overall working - can return user main menu or "safe" recovery point, instead of app turning rock. the problem this: if exception happens during initialization of page, jqm's "ispagetransitioning" flag left true. thus, won't accept more $.mobile.changepage() calls. there function in jqm called releasepagetransitionlock() fixes problem. not exposed publically, however. i hacked jqm adding method: $.mobile.releasepagetransitionlock = function() { releasepagetransitionlock(); } works perfect - i'd rather not hack jqm file. is there reasonable way access releasepagetransitionlock() within jqm's pr...

what best way handle enemies 'sliding' off of each other , preventing them overlapping? used in 3d games. i'm not sure start, thoughts? first, may make sense use existing library such box2d. secondly, sliding problem caused hit testing code. more likely, wait 2 enemies hit each other, detect hittest, , move them little bit. sliding happens repeatedly hitting, moving back, moving forward, hitting, moving back, moving forward, hitting, moving back... basic solution problem detect enemies going hit in next iteration, , avoid actual hit. need work out enemies going in next iteration, , check if, in next iteration, bounding boxes going intersect. if going intersect on next iteration, need handle 'hit'. so basically, enemies never hit or overlap. prevent it.

how select <li> element direct parent of anchor element? in example css this: li < a.active { property: value; } obviously there ways of doing javascript i'm hoping there sort of workaround exists native css level 2. the menu trying style being spewed out cms can't move active element <li> element... (unless theme menu creation module i'd rather not do). any ideas? there no way select parent of element in css. if there way it, in either of current css selectors specs: selectors level 3 spec css 2.1 selectors spec in meantime, you'll have resort javascript if need select parent element. the selectors level 4 working draft includes :has() pseudo-class works same jquery implementation . of april 2017, this still not supported browser . using :has() original question solved this: li:has(> a.active) { /* styles apply li tag */ }

i plotting bar chart in python using matplotlib.pyplot . chart contain large number of bars, , each bar has own label. thus, labels overlap, , no more readable. label displayed diagonally not overlab, such in this image. this code: import matplotlib.pyplot plt n =100 menmeans = range(n) ind = range(n) ticks = ind fig = plt.figure() ax = fig.add_subplot(111) rects1 = ax.bar(ind, menmeans, align = 'center') ax.set_xticks(ind) ax.set_xticklabels( range(n) ) plt.show() how can labels displayed diagonally? the example in documents uses: plt.setp(xticknames, rotation=45, fontsize=8) so in case think: ax.set_ticklabels(range(n), rotation=45, fontsize=8) give angle still overlap. try: import matplotlib.pyplot plt n =100 menmeans = range(n) ind = range(n) ticks = ind fig = plt.figure() ax = fig.add_subplot(111) rects1 = ax.bar(ind, menmeans, align = 'center') ax.set_xticks(range(0,n,10)) ax.set_xticklabels( range(0,n,10), rotation=45 ) plt.show(...

i think i'm missing http , https requests i have variable contains url, example: http(s)://website.com/a/b/file.html i know if there's easy way make request uri data to make http(s)request, here's have now: test if url http or https make appropriate request remove http(s):// part , put result in variable (if specify http or https in hostname, error) separate hostname path: website.com , `/a/b/file.html put variables in options objects is must or easier solutions don't involve getting out hostname , path, , testing if site in http or https ? edit: can't use http.get need put specific options in order components out of url need parse it. node v0.10.13 has stable module it: url.parse
