css - Content scrolling on mobile page with fixed header/footer -

-
hello building mobile webpage content scrolling , footer , header position:fixed - can make content doesn't scroll under header or footer , scrolls in it's own div. the reason why want going have opacity on header , footer , if content gets scrolled under , it's not looking good. heres jsfiddle made show example of scroll http://jsfiddle.net/vnvqs/ here are: http://jsfiddle.net/vnvqs/3/ i removed position: absolute scrolling part ( wrapper , scroll-content ), , added padding wrapper in order let first , last item not being under header , footer. basically, trick done using position: fixed only on header , footer , , let the rest of page scroll normal page , without using overflow: auto on specific fixed-height element. doing way, problem first lines of content under fixed-positioned header (and last ones under footer), can fix applying padding on content wrapper, as header (and footer) height. got it?

Jquery PHP - How to handle login callback on same page? -

-
simply, website allows users login. $('#login').click(function() { var user = $('#username').val(); var pass = $('#password').val(); $.post('authorize.php', { username: user, password: pass }, function(data) { //?? }); }); authorize.php verifies credentials assuring proper login. what? use jquery $.show hidden object, or load new content php page $.get or $.load ? i'm uneasy on using $.show because elements loaded dom regardless of proper login. of takes place on same page. of these 2 options better practice? or there another? using ajax request login not practice. anyway there 3 ways: you can add "blank" object dom without first, last names , other dynamic or important information , fill , show user logins. send dom object response authrize.php do not use ajax login :)

python - Can a URL be opened with a limit on the number of lines returned using urllib2? -

-
i know might sound ridiculous, possible use urllib2 open url, set number of lines returned? the reason reduce load time, large pages working with. example, page: 1. <html> 2. <head> 3. <title>hello!</title> 4. </head> 5. <body> 6. <p>hi there.</p> 7. </body> 8. </html> say open page line 5, , printing once has been read, give me: 1. <html> 2. <head> 3. <title>hello!</title> 4. </head> 5. <body> is possible @ all? sure is, can use readline() instead of read() import urllib2 req = urllib2.request('http://www.python.org') response = urllib2.urlopen(req) lines = "" x in range(10): lines += response.readline() print(lines)

i need write program calculation intensive. need load data database memory before calculation (to save time fetching data database each time. i want program webservice, , want many clients able run multiple calcuations @ same time. since load data takes quite memory, want calculations sharing same data(global data). however, if 2 users call loading same data @ same time, there synchronization issue, when 1 loading data, , 2nd begin load same data again. do need thread lock this? webservice mean multi-thread programming? plan use wws(windows web service), since c++ programmer, handled pure algorithms before, new me. sorry if confuse you. thank much. if able distinguish each client reliably, can create context each one, , context may expire if client disconnects or remains idle specified amount of time. additionally, if want allow each client multiple "calculation requests" simultaneously, need unique way identify each of these requests, , keep track ...

javascript - Nested asynchronous calls do not seem to execute as expected -

while trying out jquery, have question newbie mistake, cannot seem find solution. code: $.get("index.html", function() { var = 0; (; < 3; i++) { var ldiv = document.createelement('div'); ldiv.id = 'body-' + i; document.getelementbyid('body').appendchild(ldiv); $.get('index.html', function(data) { ldiv.innerhtml = "<p>hello world " + + "</p>"; }); } }); the output seems be <div id='body-0'></div> <div id='body-1'></div> <div id='body-2'> <p>hello world 3</p> </div> i expected ldiv.innerhtml= code executed each i, apparently executed last i? overlooking? this happens because loop completes ( i 2) before of callbacks fired. @thecodeparadox's solution works, serializes http requests. (makes them fire one-at-a-time.) allows requests execute i...

fortran - Hide full path in gfortran run-time error messages -

i using gfortran compile big program dozen of modules. whenever there error in code program generates error message line number error has happened , full path of module line belongs to. example: at line 1775 of file c:\temp\test.f90 (unit = 200, file=' ') fortran run time error: file '*' not exist my question how stop program listing full path of offending module , rather make report module name error has happened. gfortran embeds path used access source file during compilation phase. e.g. if compile full path file full path in debug output. if compile relative path relative path in output: ~/tests[520]$ gfortran -o test.x test.f90 ~/tests[521]$ test.x @ line 3 of file test.f90 (unit = 200, file = '') fortran runtime error: file '' not exist ~/tests[522]$ gfortran -o test.x ./test.f90 ~/tests[523]$ test.x @ line 3 of file ./test.f90 (unit = 200, file = '') fortran runtime error: file '' not exist ~/tests[524]$ gfortr...

i want run on table: alter table table_name modify col_name varchar(255) but table huge, has more 65m (65 million) rows. when execute, takes 50mins execute command. better way alter table? well, need alter table table_name change col_name new_name varchar(255) but, right, takes while make change. there isn't faster way change table in mysql. is concern downtime during change? if so, here's possible approach: copy table new one, change column name on copy, rename copy. you have figured out routinely changing column names in tables in production system not idea.
