is possible normrnd function of matlab generates same set of random numbers on 2 different machines (when no seed has been set)? it may if both generators seeded same way on both machine (ex. launched @ same time, , seeded current time). actually, mentionned in comment, seeding in matlab not current time, same @ launch if not seeded. if wish reproduce same series of random numbers, may take @ example: can save current seed , reuse later. save current generator settings in s: > s = rng; call rand generate vector of random values: > x = rand(1,5) > x = 0.8147 0.9058 0.1270 0.9134 0.6324 restore original generator settings calling rng. generate new set of random values , verify x , y equal: > rng(s); y = rand(1,5) > y = 0.8147 0.9058 0.1270 0.9134 0.6324 matlab gives possibility choose generator. choosing pseudo random number generator mersenne twister, , seeding same seed @ each run, same series.

is there way add jlabel jtextarea? cause try add didnt work , set visible true, allowed add jlabel inside jtextarea? through append? here current code didnt work jta = new jtextarea(); jta.seteditable(false); jta.setlinewrap(true); jta.setwrapstyleword(true); jta.setfont(new font("calibri", font.plain,16)); jlarray = new jlabel("radsjhkaljk sadf"); jta.add(jlarray); jta.setvisible(true); jsptextfield = new jscrollpane(jta); can append jlabel inside jtextarea each time message added? jtextarea not appropriate swing component insert jlabels or other components within it. can use jtextpane purpose. example , consider code given below: import javax.swing.*; import javax.swing.text.*; import javax.swing.border.*; import java.awt.event.*; import java.awt.*; class jlabeltotextpane extends jframe implements actionlistener { jtextfield tf; jtextpane tp ; jbutton click; styleddocument doc; simpleattributeset attr; public void

hi want use disqus comments system. couldnt find resource c# asp.net webforms, examples , source code or implement. have found project in codeplex , codeproject seems code in mvc haven't used mvc . can find disqus implementation code in asp.net c# webforms? not mvc. in cases implementing disqus website easy, since you're not building markup. @ minimum, need add universal code on proper page templates, links embed javascript file , "disqus_thread" div. at point make "complete" integration, need output javascript configuration variables (using unique identifier, url, , title each thread) , maybe comment counting script , should it. the webforms-specific examples might possibly need how output article's unique id, title , url variables onto page. if have idea of how that, shouldn't need existing integration.

what's submit buttons in chrome? <input type='text' placeholder='dummy input'/> <input type='submit'/> the active 'depressed' state of submit button occur if button does not have focus. reproduce, see this jsfiddle . in fact, text-field isn't necessary, allow tab focus submit button. so go ahead, place cursor in text field, press tab , click submit while button focused (orange). event fires, button not depress. pressing spacebar when focused instead of click will depress button. (thx @ineentho) gives? note: i've submitted this chrome issue tracker you use javascript/jquery un-focus textbox on hover :active properties applied when clicked. $("input[type=submit]").hover(function(){ $(this).blur(); }); also, apply css :focus pseudoclass, outline invisible. input[type=submit]:focus {outline:none;} see fiddle: http://jsfiddle.net/qahcj/1/ update i think can't solve without ja
