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.

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.

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?

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).
