i release webpage. thought, why not see how works on ipad retina. page did not good. problem can reproduced visiting link ipad retina http://www.banksalg.no/retinabug.php if @ border on right side, can see stops around 20-30 px right side of screen. green color in border body background color. if make div s smaller 1000px, example 900px acts should. you can see error on ipad retina. error not visible using "how website looks on retina screen" application/emulator. for me seems ipad cannot handle 1000px width. should when resolution 2048px. @ least 1024 px width should possible. does have solution? you haven't set viewport. default, safari on ios sets logical viewport width of 980px (per the docs ). add: <meta name="viewport" content="initial-scale=1.0"> to document's head use full logical device width.

i'm building responsive site , when browser greater 500px wide, .bio content hidden, when it's on phone, shows. good thing is, works on when page loaded within dimensions. if firefox window 400px , resize window 900, bio still visible. if load page @ 900px, bio hidden, should be. how make jquery fire again when window size changes? $(function(){ if($(window).width() > 500){ $('.speakers li').hover(function(){ $(this).find('.hide').toggle(); }); }else{ $('.speakers li .bio').removeclass('hide'); } }); figured out css using media queries, suggested mackieee. what prevented me using media queries in beginning content being hidden display:none. in case, :hover not available since there's nothing hover over. opacity trick. i guess, absolute positioning, swap z-index if needed click link under transparent div. .ease {-webkit-transition:all 0.15s ease; -moz-transition:all...

we testing hive , hadoop digging in our data , installed while hadoop 1.2.1 , hive 0.11 (was stable version) test server 4 cores , 16gb of ram. now wanted know if switching hive 0.12 , hadoop 2.2 worth trouble of upgrading server in terms of performance on queries? a query looks this: select i, day(time), count(distint value), count(*) table lateral view explode(column) tab group i, day(time); so bit of in query used couldn't find decent info on performance gain when upgrading. any insight on matter nice :) cheers since query doesn't contain "where" predicate, cannot enjoy predicate pushdown storage layer introduced in 0.12, if data in orc format. thus, although among 0.12 improvements faster plan generation , optimization count, educated guess, believe, should performance improvement not dramatic.

say i've got template this: <div id="player" ng-show="player.is_visible"> <p ng-class="player.foo_class">...</p> <p ng-class="player.bar_class">...</p> <p ng-class="player.baz_class">...</p> <div> how can narrow scope inside #player this? <div id="player" ng-show="player.is_visible" ng-inner-scope="player"> <p ng-class="foo_class">...</p> <p ng-class="bar_class">...</p> <p ng-class="baz_class">...</p> <div>

i know how login without password remote host ssh. way can access folder remote host. there way give access specific folders ssh? i used ssh-keygen generate public-private key pairs , added public key ~/.ssh/authorized_keys in remote server. you want sftponly. little involved set up, have running 2 dozen sftp clients. performs chroot when user connects , prevents ssh access -- name. https://www.allthingsdigital.nl/2013/05/12/setting-up-an-sftp-only-account-with-openssh/ note can't allow user have write access in dir log into, can bind mount other directories , give them r/w access them.

i know can set screen layout portrait or landscape in activity's xml tag in manifest prevent screen rotation. i have app shall run on phone , on tablet. on tablet want have landscape , on phone want have portrait mode. how can configuration? (and of course when device rotates screen shall not). for check whether tab or not, can use simple method: public boolean istablet(context context){ boolean xlarge = ((context.getresources().getconfiguration().screenlayout & configuration.screenlayout_size_mask) == 4); boolean large = ((context.getresources().getconfiguration().screenlayout & configuration.screenlayout_size_mask) == configuration.screenlayout_size_large); return (xlarge || large); } or public static boolean istablet(context context) { return (context.getresources().getconfiguration().screenlayout & configuration.screenlayout_size_mask) >= configuration.screenlayout_size_large; } both helpful you. for more...

i have 3 tables common fields - users , guests , admins . the last 2 tables have of users fields. here's example: users id|username|password|email|city|country|phone|birthday|status guests id|city|country|phone|birthday admins id|username|password|status i'm wondering if it's better to: a)use 1 table many null values b)use 3 tables the question less "one table many null versus 3 tables" data structure. real question how other tables in data structure refer these entities. this classic situation, have "one-of" relationships , need represent them in sql. there "right" way, , have four tables: "users" (i can't think of name) encompass , have unique id referenced other tables "normal", "admins", "guests" each of have 1-0/1 relationship "users" this allows other tables refer of 3 types of users, or users in general. important maintaining proper rel...

n log n > n -- pseudo-linear relationship. if n=1 billion , log n ~ 30; so n log n 30 billion , 30 x n , order of n . wondering if time complexity difference between n log n , n significant in real life. eg: quick select on finding kth element in unsorted array o(n) using quickselect algorithm. if sort array , find kth element, o(n log n) . sort array 1 trillion elements, 60 times slower if quicksort , index it . me sounds not big difference, need opinion of experts here. the main purpose of big-o notation let estimates ones did in post, , decide if spending effort coding typically more advanced algorithm worth additional cpu cycles going buy code improvement. depending on circumstances, may different answer, when data set relatively small: if running on mobile device, , algorithm represents significant portion of execution time, cutting down use of cpu translates extending battery life if running in all-or-nothing competitive environment, such high-f...

i want run python script in terminal don't know how? have saved file called gameover.py in /user/luca/documents/python. you need python installed on system. can run in terminal in correct directory: python gameover.py

size = 1<<16 def justread(file): open(file, 'rb') f: while f.read(size): pass the first time run function on 700mb file took 19 secs. when repeated reading same file again time took dropped 0.5secs. repeated many files , results similar. going on here? the operating system caches file in memory upon first read, , second time read memory instead of hard disk. of course memory faster.
