$(function () { // document ready $(window).scroll(function() { var top_offset = $('body').offset().top; if ((top_offset <= 650)) { $('.fluid-width-video-wrapper').addclass('fluid-width-video-wrapper-bottom'); } else { $('.fluid-width-video-wrapper').removeclass('fluid-width-video-wrapper-bottom'); } }); }); i literally can't figure out why doesn't work, should add class .fluid-width-video-wrapper if page scrolled more 650px, or remove class if isn't. can show me my-no-doubt idiotic mistake here? offset gives top , left pixel offsets of element relative document. since body element starts @ top left corner, it'll give top:0 , left:0 99% of time, unless you've done special body tag in css. what want $(window).scrolltop() which tells how far down page have scrolled.

updating fonts existing fonts i’m using 5 icomoon fonts in our website downloaded icomoon. want include 2 more fonts. should do? can add new 2 fonts existing fonts? if yes, how can add them? i'm assuming want add new "icons" existing fonts. font pack download icomoon comes "selection.json" file. if have file, import icomoon app using import icons button. after doing so, can select more icons generate new font. if don't have access "selection.json" file, import svg font using same import icons button. downside in case may need add glyph names again. anonther way save/load created fonts using project manager: main menu > manage projects. may want download project can load later. more info: https://icomoon.io/#docs/save-load

i've started r, i'm self-taught person , have problem loop. looking answers can't find anything. i've got lot of files different names , i've got lot datas in 1 file. made loop 1 file , works - it's (but has more calculations): 12bielawica9.txt looks like na na na 0.002 0.002 na na na na na na na na na na na na na na na na na 0.008 0.006 na na na na na na na na na na na na na na but it's more bigger it contains results of researches, that's why there's lot of nas. looks different reasearches....(there's less nas) wrote in r dane = dane = read.table("12bielawica9.txt", header=t) (i in dane) { x = sd(i, na.rm=t) y = length (na.omit(i)) if (y == 0) { cat(file="12bielawica9.txt", append=t, (paste("-","\t"))) } else if (x == "0") { cat(file="12bielawica9.txt", append=t, paste(format(mean(i, na.rm=t) - me...

trying figure out best way automate running command takes lot of parameters , changing of them. current approach this: #!/bin/bash # 5 more of these value=42 stuff=12 charlie=96 # note these not sequential, bad example param[0]='--oneparameter=17' param[1]='--anotherparam=foo' param[2]='--yetanotherparam=bar' param[3]='--someparam4=314' # above continues 15 parameters or # , ones one: param[16]="--someparam=astring${stuff}.foo" param[20]="--someparam20=filename${value}.foo" then call binary: ./mybinary ${param[@]} and well. then change parameter second run: param[1]='--anotherparam=bar' value=84 # here need include lines depends on value # parameter expansion work param[20]="--someparam20=filename${value}.foo" ./mybinary ${param[@]} this continues 30 runs or so... the above works it's ugly , error-prone can't figure out better way it! appreciated! thanks. if it's small nu...

updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...

i using boxlayout manager fit other jpanels horizontally. on each 1 of panels contained inside of boxlayout, box layout lays out jbuttons vertically. here visual image. i able add borders between each set of buttons, add top button says each value in column is. borders don't seem hard, not sure if possible add column header current layout manager have. do need switch layout managers, or there way add column headers each panel? glue seems idea, not sure how position header @ top, while still centering other buttons. do need switch layout managers, or there way add column headers each panel? glue seems idea, not sure how position header @ top, while still centering other buttons. wrap jpanel around each of columns borderlayout , put header in borderlayout.north . original column panel can put in borderlayout.center . there no need stick 1 layout. typically easier nest different layouts obtain result
