if animate div position right makes strange movement. happens in firefox, if have div positioned right, , if there scroll bar. why happen , how can solve it? only firefox right position with scrollbar here example simplified check: http://jsfiddle.net/lhaeh/1/ html: <div id="blue"></div> <div id="red"></div> css: #red { position: fixed; bottom: 20px; right: 25px; width:80px; height:50px; cursor:pointer; background:red; } #blue {/*this div create scroll*/ margin:0 auto; width:80px; height:500px; background:blue; } jquery: $(function(){ $("#red").click(function() { $("#red").animate({bottom:'-80px'},1000); }); }) try position: absolute; . additional explanation: assume jquery's animate() changes position absolute before starting animation, causes firefox move object bit, instead of leaving was.

i intrigued way ptunnel closes stdin, stdout , stderr: if (daemonize) { ... freopen("/dev/null", "r", stdin); freopen("/dev/null", "w", stdout); freopen("/dev/null", "w", stderr); } is way close them? confused because freopen open file descriptor, not closed in case. no. it's not entirely safe. it assumes freopen() reuses same file descriptors not guaranteed. if freopen() uses different file descriptor, example, stdout other 1 subsequent write() 's using file descriptor not work expected. because posix read/write functions use *_fileno defined as: /* standard file descriptors. */ #define stdin_fileno 0 /* standard input. */ #define stdout_fileno 1 /* standard output. */ #define stderr_fileno 2 /* standard error output. */ for respective io operations. instead do: #include<unistd.h> fd = open("/dev/null",o_rdwr); dup2(fd,0);

i'm using griddler gem in rails 3.2 app handle incoming emails attachments. the documentation indicates attached files multipart/form-data files. is there easy ruby way interrogate these files , determine filetype? need handle different filetypes using different methods. according rails guide under section 5 'uploading files' the object in params hash instance of subclass of io. depending on size of uploaded file may in fact stringio or instance of file backed temporary file. in both cases object have original_filename attribute containing name file had on user’s computer , content_type attribute containing mime type of uploaded file. so interrogate uploaded_io.content_type , use different methods work whatever content_type is. hope gets started in right direction

i'm serving 1 page app. app needs request initial data server once it's loaded. is there anyway dynamically serve data initial asset load of css/html/javascript, without rendering in html? sending js object data don't need ping server? inserting script tag? adding dynamically created js file asset load? a little bit lost, appreciated. in opinion, best way serve dynamic content node.js server client use socket.io . if don't wanna use socket.io, can try create dynamic page acts different on node.js server, , use xmlhttprequests receive data.

my application has number of domain model objects i've built , unit tested. there nothing angular-specific them, have no angular dependencies, , use them if had selected other framework besides angular. my question proper way use them within angular. need use them in controller. i'm including them before angular controller code, defined , can refer them. i'd know if there better way? should using angular's dependency injection system inject them? if so, how? thanks. you should stick them in service. can injected / mocked / tested / di-is-fun-ed easily. before: var superbigthing = { isawesome: true; }; after: myapp.factory('superbigthing', function() { var superbigthing = { isawesome: true }; return superbigthing; }); myapp.controller('thingctrl', function($scope, superbigthing) { });

my application should read , write file. , work might happen in multithread, should synchronize resource. here code : // write file fileoutputstream fos = openfileoutput("data.dat", context.mode_private); synchronized (fos) { objectoutputstream writer = new objectoutputstream(fos); // continue write } // read file fileinputstream fis = openfileinput("data.dat"); synchronized (fis) { objectinputstream reader = new objectinputstream(fis); // continue read } does above code safe ? means "data.dat" can read or write, , in 1 thread ? if wrong, please correct me. thanks :) use file locking: http://en.wikipedia.org/wiki/file_locking tell other threads output file in use. if output file exclusively used app synchronized should prevent other threads doing portion of code @ same time. or, finally, can consider using intentservice queue requests , handle them 1 one

so designing program want able recompile script inside program. possible? in addition want able recompile regardless if python installed on machine. insight or recommendations appreciated. for first part of question: save file called "hello_world.py" import os print "hello world" os.system("python hello_world.py") of course, python doesn't compile. for second part of question, use cx_freeze , py2app , py2exe , pyinstaller , etc.

im trying submit form via jsroutes , ajax , dont think im getting controller .... this routes post /submit controllers.application.submit() and jsrouts function: $('#submit').click(function() { jsroutes.controllers.application.submit().ajax({ data : $("#contact-form").serialize(), url: '@{application.submit()}', success : function(data) { alert("succsses"); }, error : function(err) { alert("error"); } }); }); this im sendig server http://localhost:9000/?name=ajax&lastname=aaa&email=miko5054%40hotmail.com&phone=453534 what im doing wrong here ??? the @{application.submit()} code incorrect. should @{routes.application.submit()} . but if use javascript router jsroutes.controllers.application.submit() , don't need specify url inside ajax() call. can remove url:... line , should work fine.

i working on converting interface of perl web application ext , intended use cgi-extdirect-2.02 library. i encountered problem though, which, after many hours of struggling, still remains unresolved. in simplest use case problem is: when adding following lines action method, example, demo/testaction/getgrid , error occurs in router.pm . same error appears both when executed under apache or using included library p5httpd.pl server. when remove while(<file>) loop, error goes away , else works fine. system configuration is: sunos 5.10, apache 2, perl 5.12.1. lines add: open(file, "</tmp/test.txt") or die("can't open file: $!"); while (<file>) { ; } close(file); error: 5571 17:58:08 server started on port 5000. 5571 17:58:08 5571 17:58:08 point browser @ http://localhost:5000 5571 17:58:11 <- localhost: /direct-grid.html http/1.1 5571 17:58:11 -> 200 ok /direct-grid.html: 803 bytes sent text/html 5571 17:58:11 <

in application have user model has many relationship status_updates model. currently, database has 1 user , 0 status_updates saved. what bizarre when search status_updates or relationship between these objects in consol, affirms nil status_updates in database. statusupdate.count (0.2ms) select count(*) "status_updates" => 0 statusupdate.any? (0.1ms) select count(*) "status_updates" => false user.status_updates.count (0.2ms) select count(*) "status_updates" "status_updates"."user_id" = 1 => 0 user.status_updates.any? (0.2ms) select count(*) "status_updates" "status_updates"."user_id" = 1 => false so, that's clear me. but, when in application write following, status_update object returned! def end_date if self.status_updates.any? == false return self.status_updates.any? elsif self.status_updates.any? == true return self.status_updates.first en

i'm working wicket, building set decoupled components. while using event driven mechanism let components communicate, i'm keeping set in class "genericcomponent". basic idea send event, "someevent.class" payload extends igenericevent. in onevent method genericcomponent class, go through events added set. if class matches payload, event should executed. now code: genericcomponent public class genericcomponent<t> extends genericpanel<t> { //... protected set<igenericevent>eventset = new hashset<igenericevent>(); //... public void addevent(final igenericevent event) { boolean result = eventset.add(event); if (!result) { throw new illegalargumentexception("event added ..."); } } @override public void onevent(final ievent<?> event) { (igenericevent e : eventset) { if (e.getclass().equals(event.getpayload()))

i've tried using decimal (2,2) won't let me use this. i want store number, example 7.50 or 10.50. need keep both numbers after decimal though when refresh database resets values 0.99. suggestions? the first digit of decimal declaration total digits. want use decimal (4, 2) . allows 2 digits before decimal , 2 after. documentation: https://dev.mysql.com/doc/refman/5.7/en/precision-math-decimal-characteristics.html

i have picture of checkerboard taken arbitrary camera angle. find 2 vanishing points corresponding 2 sets of lines form checkerboard grid. these 2 vanishing points, compute homography checkerboard plane image plane. i apply inverse homography re-render checkerboard top view. however, images, re-rendered top view large. is, due camera angle, inverse homography stretches parts of image (i.e. regions of image close 1 of vanishing points) large. this takes unnecessarily large amount of memory, , of region becomes highly stretched stuff not need. so, when applying inverse homography, avoid rendering regions of image highly stretched. way this? (i coding in matlab) if need render checkerboard, without background, extract 4 corners of checkerboard , compute homography maps them 4 corners of square. then can obtain rectified image of checkerboard warping input image homography, paying attention render needed region (ie square on map checkerboard).
