i have local web server on raspberry pi using kiosk rotating photos. trying include coolclock.js script on page have working, canvas clock lives in move when photo changes doesn't burned in on tv pi hooked to. cannot clock move on page though... function rotateimages() { var canvas = document.getelementbyid('clockid'); alert(canvas.style.top); alert(canvas.style.left); if(last==1){ document.body.style.backgroundimage='url('+preloads2.src+')'; num=math.floor(math.random()*preloads.length); preloads1.src=preloads[num]; last=2; canvas.style.top = '0px'; canvas.style.left = '0px'; } else{ document.body.style.backgroundimage='url('+preloads1.src+')'; num=math.floor(math.random()*preloads.length); preloads2.src=preloads[num]; last=1; canvas.style.top = '500px'; canvas.style.left = '500px'; } } var myvar=setinterval(function(){rotateimages()},...

i'm using serialport in c# , code this: filestream myfile = new filestream(strfiledestination, filemode.append); binarywriter bwfile = new binarywriter(myfile); bwfile.write(serialport1.readexisting()); bwfile.close(); myfile.close(); when use bwfile.write(serialport1.readbyte()); instead of bwfile.write(serialport1.readexisting()); , writing speed in file decreases 130 kb/s 28 kb/s , when use bwfile.write((byte)serialport1.readbyte()); , writing speed decreases 7 kb/s. want know how can write in file third command , have speed 130 kb/s. have considered using stream write data? don't think using features binarywriter offers on stream.write. simply call copyto() method stream destination = new filestream(...) myfile.copyto(destination); which under hood calling following code: byte[] buffer = new byte[buffersize]; int read; while ((read = serialport1.read(buffer, 0, buffer.length)) != 0) { destination.write(buffer, 0, read); } have @ po...

i've written footeradapter seems work perfectly. i realised viewholder has field mposition among others hold state in each element leading me suspect header not achievable usage of decorator pattern, because hold different position in each adapter . that is, except if wrapper/decorator adapter didn't alter other elements. say: footers ok, long data not need binded them. if wrapper adapters possible need more access viewholder? i'm not sure how fields intended usage: headerview = new view( context ); footerview = new view( context ); myadapter myadapter = new myadapter(); headeradapter headeradapter = new headeradapter( myadapter , headerview ); footeradapter footeradapter = new footeradapter( headeradapter , footerview ); recyclerview recyclerview = new recyclerview(); recyclerview.setadapter( footeradapter ); this cool, because add headers & footers arbitrary adapter , not have worry indexing , offsetting item counts. footeradapter.java publi...

a twelve factor app expected store configuration in environment . is intended include ssl certificate , key files, can "large" (multiples of kb @ least), , (depending on format), contain non-printable characters (newlines @ minimum). or environment expected point cert/key file names?
