i'm new this. i used jquery make 3 divs (buttons) slidedown @ page load. made them expand little (downwards) when mouseover'd. worked in safari not in firefox. changed around few things. now have css animations make them expand on hover , jquery function make them slidedown on load. slidedown doesn't seem work properly. html: <div class="header"> <div class="button_container"> <a href = "../index.htm"><div class="header_button home_button">back home</div></a> <a href = "../projects/projects.htm"><div class="header_button projects_button">projects</div></a> <a href = "../resume/resume.htm"><div class="header_button resume_button" >resume</div></a> </div> </div> css: .header_button { display: inline-block; height: 130px; line-height: 130px;

the following behaves differently between jquery 1.9 , 1.10+: <select id="s1"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> </select> $('#s1 option[value=1]').hide(); $('#s1').val(''); the idea behind code select first non-hidden option, after hiding options, including selected one. since jquery 1.10+ $('#s1').val(''); no longer selects first non-hidden option, while .val(<some proper value particular select box>) works ok. trying following approaches not because both selectedindex , .first().val() consider hidden options: $("#s1").prop("selectedindex", 0); $('#s1 option').first().prop('selected', true); next thing comes mind (also suggested c-link ) not work, because :visible selector not work select options. $('#s1 option:visible'

i working on numa system 2 nodes. got pointer pointing memory, not know node in. there way can node number of memory? (the reason getting node mask of current thread not work that, memory of node full, thread affined current node, may still allocate memory on adjacent node. therefore, seeking direct way memory location.) you may want check numa api: http://linux.die.net/man/3/numa . cursory look, numa_alloc_onnode() , numa_get_run_node_mask() stand out useful. may combination of functions in api can address reason why want know node number.

i load image, , read pixels find rgb, check next pixels across make sure match, , @ right position of bitmap. i know below code wrong, not sure how go correcting it. know pixels not fastest way read pixels. thanks guys! procedure rgb(col: tcolor; var r, g, b: byte); var color: $0..$ffffffff; begin color := colortorgb(col); r := ($000000ff , color); g := ($0000ff00 , color) shr 8; b := ($00ff0000 , color) shr 16; end; procedure tform1.button1click(sender: tobject); var x,y : integer; colorn: tcolor; r, g, b: byte; begin y := 0 image1.picture.bitmap.height -1 begin x := 0 image1.picture.bitmap.width -1 begin inc(i); colorn := image1.canvas.pixels[x, y]; rgb(colorn, r, g, b); //memo1.lines.append('line: '+inttostr(i)+' y: '+inttostr(y)+' x: '+inttostr(x)+' r: '+inttostr(r)+' g: '+inttostr(g)+' b: '+inttostr(b)); if (inttostr(r) = '235') , (inttostr(g) = '235'

i have created async task background task.in async task class have made interface method finish.it used let me noe background task over.but when ever using interface getting null async class public static class searchjobsasync extends asynctask<string, string, string> { string response; boolean value; context c; finished finished; public searchjobsasync(context c, searchjobsasync.finished finished,boolean value) { this.c = c; this.finished = finished; this.value=value; } public static interface finished { void finish(boolean finish); } searchjobsasync(context c, boolean value) { this.value = value; this.c = c; } @override protected string doinbackground(string... strings) { if (spyears.getselecteditemposition ()

i ask how query select data having datetime minute ago until ? ex : result data 5 minute ago (field: input_time) until .. this query select * operasi timestamp(input_time) <= timestamp(now()) , order input_time desc limit 0,10 you should query as: select * operasi input_time <= now() , input_time >= date_sub(now(), interval 5 minute) order input_time desc limit 0, 10; this structure allow query take advantage of index on input_time . if wrap column in function, less likely.
