Is this possible?I want to exclude android phones from using some code, but I still want it to work on android tablets.The only user agent I can find is “android” which will obviously exclude everything android related :/Thanks

php javascript html 2014-1-26 2:43:28
I have just started to learn HTML, JavaScript and PHP. After studying little , I am thinking why we need PHP? Whatever we can do by PHP, can be done using Javascript(I think that but I am a noob to this). So why we are using PHP? Can anybody explain me about this?( I apologizes in advance if the question is totally foolish and the answer is very obvious but as I said I am noob to web).

javascript parsing code-generation interpreter ast 2014-1-26 0:25:49
I wrote an interpreter in JavaScript for a small language using jison, which is a JS port of bison. The language is used to evaluate expressions and conditions. Right now the evaluation is mixed with the parsing.I’m trying to optimize it and the bottleneck is lexer and the parser. So I decided to parse it before hand and only evaluate on runtime.The question is that which one is faster or cleaner, generate JS code before and only run that or generate AST and iterate on it on runtime?

objective-c javascript 2014-1-25 19:00:16
In C or any ECMAscript based language you ‘call a public method or function’ on an object. But in documentation for Objective C, there are no public method calls, only the sending of messages.Is there anything wrong in thinking that when you ‘send a message’ in ObjC you are actually ‘calling a public method on an Object’.?

I have a JavaScript object that I’d like to add some properties to, but I don’t know what the names of the properties are until runtime.Can I do this without using eval? If so, how?var get_params = new Object(); var params = {‘name’:’john’, ‘age’:’23’}; //actually not known until runtime for (var i=0, len=params.length; i<len; ++i ){ get_params.p[0] = p[1]; //How can I set p[0] as the object property?} }

javascript node.js socket.io 2014-1-22 12:25:59
So I would like to be able to run custom function through socket.io using node My basic idea is fairly simple, I just can’t get it to work. Generally speaking you would write something similar to this to run a function on incoming message…//server socket.on(‘incomingMessage’, function(data) {console.log(data);io.sockets.emit(‘newMessage’, {id: data.id, from: data.name, message: data.message}); }); //client socket.on(‘newMessage’, function(data) {$(‘#messages’).html($(‘#messages’).html() + data

node.js socket.io 2014-1-12 1:13:42
In socket.IO there are 2 ways to send message to users separately: rooms and namespaces. In my project I need both of them – namespaces to divide users of different applications and rooms for each namespace for private messages and other specific stuff. It’s quite easy to create rooms directly in runtime. But is it possible to do the same trick with namespaces? I’d like to do something like this:io.of(*someFunctionToCreateNameSpaceInRuntime*) .on(‘connection’, function (socket) {socket.emit(***)

I am working now on real-time game based on tornado, tornado-sockjs. There are a lot of different timeout strategies in our game application: TIMEOUT_GAME_IF_NOBODY, TIMEOUT_GAME_IF_SERVER_OFF. These timeouts has callbacks that can work with storage directly (update, insert, and so on). The question is what is the right way to organize timeout strategy into a module ?! How can we re-execute callbacks in case of server failure ? Imagine that three timeouts are hanging, and suddenly server that ha
