i considering developing software safely storing files on server. let's have secret document stored on client computer want upload server. requirements here file on server should encrypted @ times , since private key on client, unreadable accessing server directly. maybe can javascript or maybe need develop full fledged app handle upload. either way ok need able download , decrypt file using web browser only. this got me thinking. can configure https (ssl) in way can precalculate encrypted response server client. in case can while uploading , when document requested can return pre-encrypted data decrypted ssl stack on client. i know there random number exchange prevents this. there way configure ssl response server client same always. in case replay attacks server client acceptable , not issue. in ssl handshake, client generates pre-master secret used derive session key. since appear have control on server, cannot prevent client steering conversation in particula

(with unique personorder.orderid ). in case might model association regu

let's have: var details = { method: 'post', url: 'http://example.com/', async: true, params: {'param1': '1', 'param2': '2'}, headers: {'if-modified-since': 'sat, 1 jan 2000 00:00:00 gmt', 'cache-control': 'max-age=0'}, contenttype: 'text' }; kango.xhr.send(details, function(data) { if (data.status == 200 && data.response != null) { var text = data.response; kango.console.log(text); } else { // went wrong kango.console.log('something went wrong'); } }); is there way wrap more neatly somehow - variables change / post, i'm thinking like: call('post', function(data) {}); is possible? i'm not familiar enough js. just wrap logic in function this: function getdata(method) { var details = { method: method,

i'm working on subclass extends relativelayout, , have onscalegesturelistener . want when scale on view, height of change(it's scalaing, resizing object). takes me exception don't know how can interprete it. my code is: public class simpleonscalegesturelistener extends simpleonscalegesturelistener { @override public boolean onscale(scalegesturedetector detector) { tmpscale = detector.getcurrentspan() / detector.getpreviousspan(); log.d("debug", ".getcurrentspan() "+detector.getcurrentspan()); log.d("debug", ".getpreviousspan() "+detector.getpreviousspan()); log.d("debug", ".getscalefactor() "+detector.getscalefactor()); scaling = true; relativelayout.layoutparams params = new layoutparams(kticketwidth, (int) (getmeasuredheight()*mscalefactor)); setlayoutparams(params); //invalidate(); requestlayout(); return true; }

how many binary trees can find have n node , height of these tress n-3? the total number of binary tree possible n nodes = ( 2n c n ) / (n+1) . the minimum depth of binary tree ⌊log 2 n⌋ , maximum depth n-1 . so in each level level there [( 2n c n ) / (n+1)] / [(n-1) - (⌊log 2 n⌋)] nodes.

this load content page , change url. problem button , forward won't load content agin. change url. how can make them load function? <a onclick="load_content('p1');" >page1</a> <a onclick="load_content('p2');" >page2</a> function load_content(name) { window.history.pushstate(null, null, "/?page=" + name + ""); var xmlhttp; if (window.xmlhttprequest) {// code ie7+, firefox, chrome, opera, safari xmlhttp=new xmlhttprequest(); } else {// code ie6, ie5 xmlhttp=new activexobject("microsoft.xmlhttp"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readystate==4 && xmlhttp.status==200) { document.getelementbyid("response").innerhtml=xmlhttp.responsetext; } } xmlhttp.open("get","load_content.php?name=" + name + "",true); xmlh
