i'm building twitter-bootstrap site has 2 columns: narrow side column , main article column. on each page, widths of columns fixed , heights depend on how inside them. side column's height must match main column's, main column's height variable. on pages, main column short because there aren't many articles inside while on other pages height longer. when main column's height taller side column's, side column's increases. my question is, best methods/technologies implement this, without using cms? i'm thinking classes, maybe along lines of masonry css...but not quite sure start. smaller-screen version, i'm planning align them 1 column, won't need responsive. i've prepared crude drawing of i'm trying accomplish: if can away it, recommend using flex box . if not, here css solution http://plnkr.co/edit/geevztduy4pdejqvnhmp?p=preview html: <body> <div class="container"> <div class=&quo

i'm writing simple loop in lua lÖve game i'm developing. understand i'll waste more time worrying ever spent on cpu clock cycles answer question saves me, want deeper knowledge of how works. the current body of loop so: local low = mid - diff local high = mid + diff love.graphics.line(low, 0, low, wheight) love.graphics.line(high, 0, high, wheight) i want know if more computationally efficient keep or change to: love.graphics.line(mid - diff, 0, mid - diff, wheight) love.graphics.line(mid + diff, 0, mid + diff, wheight) with second body, have calculate low , high differences twice each. first, have store them in memory , access them twice each. which more efficient? the short answer it'll unlikely make difference @ all. if there kind of difference, code next drawing line, example. drawing aliased line optimized bresenham implemented in native code enormously expensive in comparison add , subtract. function call alone dwarf cost.

i running netbeans 8.0.2 (first time netbeans user) , when run gui program, text on buttons or frame disappears or gets garbled when hover on them, if had refreshing problem. i used eclipse before , had same problem set binary/exe files eclipse use second/dedicated graphics card , solved problem. unfortunately, did not work on netbeans, , workaround disable cleartype on windows system, it's pain switch on , off everytime i'm working in netbeans hoping find fixes or better workarounds folks here. so know fix? , have encountered before? here attached screenshot of how looks i found fix: -update graphics card driver, in case, intel hd 4000. solved problem.

html <main> <div class="homediv"> <p>test</p> </div> </main css div.homediv { background-color: yellow; width: 100%; position: static; /*the lower z-index, further in background element*/ z-index: -1; } at first glance, should make div horizontally fill screen. did not. few answers on here said width:100% work when width of parent set, set. ensure that, gave html, body, main , div width:100% attribute. did not fix it. after trying around in chrome devtools, found out main fill screen width. contained seemingly pre-set attributes had remove. google told me padding , margin - if not specified - set browser, fix css, had add main { padding:0; margin:0; } i posted here in hopes helps somebody, if reason believe should not on here - maybe because might seem noobish mistake - guess can understand if gets downvoted

i combine array full of floats array full of strings. there way this? (i having trouble rounding floats, insert changing them scientific notation; unable reproduce small example) a=np.array([[1/3,257/35],[3,4],[5,6]],dtype=float) b=np.array([7,8,9],dtype=float) c=np.insert(a,a.shape[1],b,axis=1) print(np.arround(b,decimals=2)) d=np.array(['name1','name2','name3']) how append d onto end of c in same way appended b onto (insert d last column of c)? i suspect there type issue between having strings , floats in same array. answer questions if there way change float (or maybe scientific number, numbers displayed '5.02512563e-02') string 4 digits (.0502). i believe concatenate not work, because array dimensions (3,3) , (,3). d 1-d array, d.t no different d. also, when plug in "valueerror: input arrays must have same number of dimensions." i don't care accuracy loss due appending, last step before print. try making d nump

i need hide class if doesn't have class active . $(document).ready(function() { if (!$('.active').hasclass('active')) { $(this).hide(); }; }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="subheader active"> <p>hello</p> </div> <div class="subheader"> <p>goodbye</p> </div> <div class="subheader"> <p>hello again</p> </div> to hide subheader doesn't have class active , use $('.subheader:not(.active)').hide(); a better solution be, think, use pure css this: .subheader { display: none; } .subheader.active { display: block; } as demonstrated in snippet, uses jquery toggle class, , uses css decide happens visually. $('.subheader').on('click', function(){ $('.subheader').togglecl
