i using imageview s in app set cornerradius make them circular. works fine, when verify in iphone 6 , 6 plus, parts @ edge seem cut off, eg. top part in image below: note haven't added 3x launch image, app displayed scaled version of original. assuming issue happens because of scaling factor. i.e. width specify in code not see in device. also, assume fixed if use autolayout. are assumptions correct? if not, please provide explanation , solution same. :) ! edit1: my imageview of 35 x 35 size. set corner radius follows: [commentcell.profileimageview.layer setcornerradius:17.5]; [commentcell.profileimageview.layer setmaskstobounds:yes]; edit2: floating points doesn't seem it, because tried same frame size 36 x 36 , corner radius 18 . your assumptions correct, there solution : [commentcell.profileimageview.layer setcornerradius:profileimageview.frame.size.width/2];

when using <video> tag alone, 1 adds crossorigin attribute so: <video src="blah" crossorigin="anonymous"></video> however, i've had trouble finding out correct placement of 'crossorigin' when using multiple video sources , example: <video> <source src="/somesource.mp4"> <source src="/somesource.webm"> </video> do put 'crossorigin' attribute on <video> tag or individual <source> tags? if later, mean each source can have individual crossorigin handling within 1 video tag? do put 'crossorigin' attribute on tag or individual tags? the w3c specs specify crossorigin attribute on video tag (or more precisely htmlmediaelement) not on src element (or again more precisely, htmlsourceelement). so, assuming follows specs, rash assumption - see margus's answer exmple, should put cross origin attribute on video tag rather individual source ...

i have seen many solutions check if our own app minimized,running or background.but there way check if app package running or minimized based on can run code.like app-locker.here need turn off network apps according user selection on installed apps in device, when selected apps on foreground, network should disabled when selected apps closed or minimized.then enable network. compliant google play if make such app? because somewhere read don't allow apps interfere other apps.so confused. tl;dr: google doesn't want this, , shouldn't try. the old hack relied on activitymanager#getrecenttasks() find out app in foreground disabled starting in android 5.0. app lockers work on lollipop using new hack involving activitymanager#getrunningappprocesses() . how works described in this answer . this hack reportedly broken on android m. there's new usagestats api might able glean bit of info, requires permission can granted system activity. it's documente...

this code seems work , takes list of files , compresses them in format pandas can read, , combines them 1 location. edit - modified code add new files (based on file not existing in tar). os.chdir(r'c:\\users\documents\ftp\\') saveloc = r'\\fnp\mydownloads\\' compression = "w:bz2" extension = '.tar.bz2' filename = 'global_performance' filetype = 'performance_*.csv' tarname = saveloc+filename+extension files = glob(filetype) tar = tarfile.open(tarname, compression) file in files: if file not in tarname: tar.add(file) tar.close() filename = 'global_status' filetype = 'status_*.csv' tarname = saveloc+filename+extension files = glob(filetype) tar = tarfile.open(tarname, compression) file in files: if file not in tarname: tar.add(file) tar.close() is there way pandas read tar file? can specify file know exists within file, or perhaps concat of files 1 read? being able add new files nice...

i using xcode7 beta2 play around swift 2. trying use file-selection dialog ( nssavepanel ) brought me trouble. running following code clicking associated button won't bring dialog sheet (not @ all) make window's decoration disappear, leaving in broken state otherwise functional sheets open dialogs without decoration. using call deprecated api beginsheetmodalforwindow , in commented line, works expected. @ibaction func openfileclicked(sender: anyobject) { let openpanel = nssavepanel() openpanel.cancreatedirectories = true //openpanel.beginsheetmodalforwindow(self.view.window!, completionhandler: { openpanel.beginsheet(self.view.window!, completionhandler: { (result) -> void in print("opening:\(result)" ) }) } is code broken somehow or there issue api calling.

i want donut optionally relate donut, , if so, other donut relate back. i've read, believe need set parent/child relationship, though in real world, it's optional pairing (donuts can exist happily, or exist in pairs). here current setup: public class donut { public int id { get; set; } public int? parentdonutid { get; set; } public int? childdonutid { get; set; } // virtual properties public virtual donut parentdonut { get; set; } public virtual donut childdonut { get; set; } } this statement in mapping file gets me close, insists on creating new key named parentdonut_id on table instead of using existing parentdonutid : this.hasoptional(t => t.childdonut) .withoptionalprincipal(t => t.parentdonut); but when try mapping: this.hasoptional(t => t.childdonut) .withoptionalprincipal(t => t.parentdonut) .map(m => m.mapkey("parentdonutid")); // or "childdonutid" i error...

it possible write hdf5 stdout , read stdin (via h5::file file("/dev/stdout",h5f_acc_rdonly) or otherwise)? what want have program foo write hdf5 file (taken first argument, say) , program bar read hdf5 file , instead of command_prompt> foo temp.h5 command_prompt> bar temp.h5 command_prompt> rm temp.h5 simply say command_prompt> foo - | bar - where programs foo , bar understand special file name - mean stdout , stdin respectively. in order write programs, want know 1) whether @ possible , 2) how implement this, i.e. pass h5fcreate() , h5fopen() , respectively, in case file name = - . i tried , seems impossible (not big surprise). hdf5 has h5fcreate() , h5fopen() , , h5freopen() , neither of seems support i/o stdin/stdout . i not think can use stdin hdf5 input file. library needs seek around between header contents , data, , cannot stdin .

i know how load balancers work http requests. client opens connection lb, lb forwards request backend servers, lb gets response , same connection sends response client , closes connection. want know internal details of load balancer websockets. how connections maintained , how response sent client. read many questions on stackoverflow none of them gave clear picture of internal implementation of lb the lb route connection server behind it. so long keep connection open keep being connected same server , not communicate lb again. depending on client, on reconnection routed server. i'm not sure how works when libraries fallback json-p tho
