我想在CENTOS服务器中运行python脚本:

#!/usr/bin/env python
import socket
try:    
    import thread 
except ImportError:
    import _thread as thread #Py3K changed it.
class Polserv(object):
    def __init__(self):
        self.numthreads = 0
        self.tidcount   = 0
        self.port       = 843
        self.sock       = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.sock.bind(('100.100.100.100', self.port))
        self.sock.listen(5)
    def run(self):
        while True:
            thread.start_new_thread(self.handle, self.sock.accept()) 
    def handle(self,conn,addr):
        self.numthreads += 1
        self.tidcount   += 1
        tid=self.tidcount
        while True:
            data=conn.recv(2048)
            if not data:
                conn.close()
                self.numthreads-=1
                break
            #if "<policy-file-request/>\0" in data:
            conn.sendall(b"<?xml version='1.0'?><cross-domain-policy><allow-access-from domain='*' to-ports='*'/></cross-domain-policy>")
            conn.close()
            self.numthreads-=1
            break
        #conn.sendall(b"[#%d (%d running)] %s" % …

如何在Phaser.P2.body中施加摩擦力？在基于Air-Hockey移相器的游戏中.如何从曲棍球台"关闭气流"？

在这个例子中:http://jsfiddle.net/ywzmkso3/32/

// Initialize Phaser, and creates a 400x490px game
var game = new Phaser.Game(400, 400, Phaser.CANVAS, 'game_div');
var game_state = {};

// Creates a new 'main' state that wil contain the game
game_state.main = function() { };  
game_state.main.prototype = {

preload: function() { 
    // Function called first to load all the assets
},

create: function() { 
    game.physics.startSystem(Phaser.Physics.P2JS);
    game.physics.p2.restitution = 0.7;

    //start drawing a circle
    var graphics = game.add.graphics(0, 0);
    graphics.beginFill(0xFF3300);
    graphics.lineStyle(0);
    graphics.beginFill(0xFFFF0B);
    graphics.drawCircle(100, 100, 40);
    graphics.endFill(); …

我使用node.js和Net模块的服务器的非常基本的脚本...我从IP接收可疑连接.我可以添加所有我不想连接的ips ...它的自动:当用户不认证时,我将他的IP推入一个数组并关闭套接字.如果他重新连接Im验证他的IP是否在数组中,如果为true,我再次关闭套接字.如何在IP连接到服务器之前验证此黑名单数组？这是什么方式？

我正在为应用程序制作SplashScreen ...当应用程序启动时,它启动LoadingActivity ...睡眠3秒,完成(); 然后启动MainActivity.Splash用于更新数据库.如果数据库已经更新,我仍然希望启动仍然持续3秒.

我使用以下代码:

protected void onPostExecute(Void result) {
    super.onPostExecute(result);
    try {
        Thread.sleep(3000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    } finally {
        Intent intent = new Intent(LoadingActivity.this, MainActivity.class);
        startActivity(intent);
        finish();
    }
}

这是一个糟糕的实践吗？为什么？该应用程序正在AVD中运行.

我在Windows 7 cmd提示,,,我试图通过以下方式安装: npm install node-mysql

我得到这个:

我在CENTOS的服务器www.domain.com上创建了一个cron作业:

*/10 * * * * http://www.anotherdomain.com/cron/task.php

但它的回归:

/bin/sh: http://www.anotherdomain.com/cron/task.php: No such file or directory

如何使其工作？

我开始使用异步编程,我正在创建一个nodejs应用程序,我在一些文件中切片代码:index.js,ctlUser.js,DAO.js等... .. Index.js是它需要的主文件ctlUser和ctlUser需要DAO.js ... DAO连接数据库并执行查询...

抽象,我的结构是这样的......

Index.js

var ctlUser =  require('./ctlUser.js');
var username = ctlUser.getUserName('1');
console.log("Return from ctlUser" + username);

ctlUser.js

var DAO = require('./DAO.js');
var getUserName = function(id){
    var userName = DAO.executeQuery("SELECT username FROM tbUsers WHERE id = " + id );
    console.log(Return from DAO = userName);
    return username;
}

DAO.js在这里一切都很好......

var mysql      = require('mysql'); 
var executeQuery = function(query) {    
        var connection = mysql.createConnection({
            host        : SERVER,
            user        : USER,
            password    : PASSWORD,
            database    : DATABASE
        });
        connection.connect();
        connection.query(query, …
