我可以在服务器上ping pong redis

# redis-cli ping
PONG

但远程问题:

$ src/redis-cli -h REMOTE.IP ping
Could not connect to Redis at REMOTE.IP:6379: Connection refused

在配置中我得到了标准端口:

# Accept connections on the specified port, default is 6379.
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379

那么也许我应该在远程ubuntu机器上打开端口6379？怎么做？

我偶然在项目文件夹中添加了9000多张照片.并承诺他们.然后从磁盘中删除它们.承诺.

现在我尝试将更改推送到git服务器.但它需要太长时间并尝试发送12 Gb的数据.

我检查了磁盘上的文件大小,看到真正的.git文件夹需要12 Gb.

如何从那里删除照片？我试过了git rm,但失败了:

? git rm public/photos
fatal: pathspec 'public/photos' did not match any files

因为我已经从磁盘上删除了它们,但它们仍然在.git文件夹中.

我试图添加public/photos到.gitignore:

public/photos/
*.zip

但没有结果.当然,我可以hard reset head在我的项目中没有这么多垃圾照片.但从那时起我多次承诺并在代码中做了很多改变.

如何在visual studio 2012的调试输出窗口中禁用消息？

线程''(0x2360)已退出,代码为0(0x0)

由于这些消息的数量如此之高,他们会打扰我并隐藏我使用的自定义调试信息Debug.Write.我应该使用红色突出显示我的自定义调试信息吗？

我试图从转储恢复mongo但失败了:

mongorestore --port 27133 dump
2015-05-07T09:39:11.760+0300    Failed: no reachable servers

虽然我可以毫无问题地连接到它:

$ mongo --port 27133
MongoDB shell version: 3.0.1
connecting to: 127.0.0.1:27133/test

在日志文件中没有什么特别的:

我尝试使用nosetests
❯nosetests'/ pathTo/test'

但它python 2.7用于我的测试:

sys.version_info(major=2, minor=7, micro=5, releaselevel='final', serial=0)

所以有些人失败了,因为他们写的是python 3.3.

我解决它并安装虚拟环境:

pyvenv-3.3 py3env

激活它:

source ~/py3env/bin/activate

检查虚拟环境中的python virsion:

? python --version                                                                                 ?
Python 3.3.3
(py3env)

好.但是nosetest仍然python2.7在虚拟环境中使用:

sys.version_info(major=2, minor=7, micro=5, releaselevel='final', serial=0)

所以我的测试失败了. 如何让鼻子使用python3？

当我安装iconv时npm出现以下错误:

我正在尝试node.js selenium web驱动程序示例 ...

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
   usingServer('http://localhost:4444/wd/hub').
   withCapabilities(webdriver.Capabilities.chrome()).
   build();

driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.wait(function() {
 return driver.getTitle().then(function(title) {
   return title === 'webdriver - Google Search';
 });
}, 1000);

driver.quit();

......但是得到了错误

promise.js:1542
      throw error;
            ^
UnknownError: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see http://code.google.com/p/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://code.google.com/p/chromedriver/downloads/list

我猜想设置PATH变量:

$ cat .bashrc

export …

我正在试图获得异步函数的执行时间.貌似我可以使用process.hrtime.我创建了简单的例子:

console.log("starting");
var start = process.hrtime();
console.log("start");
console.log(start);

setTimeout(function(){
    console.log("HELLO");
    var end = process.hrtime();
    console.log("end");
    console.log(end);
}, 1000);

它输出

starting
start
[ 131806, 731009597 ]
HELLO
end
[ 131807, 738212296 ]

但我不明白在几分之一的时间里,执行时间在哪里？我期望在这个例子中得到1000毫秒.

我下载了用asp.net mvc3 visual studio 2010编写的示例源代码

visual studio 2012打开解决方案文件.它将源代码转换为2012并打开解决方案.

当我构建解决方案得到错误:

错误1'c:\ Program Files(x86)\ Microsoft ASP.NET\ASP.NET MVC 3\Assemblies\System.Web.Mvc.dll'和'c'中存在类型'System.Web.Mvc.ModelClientValidationRule' :\ Program Files(x86)\ Microsoft ASP.NET\ASP.NET Web Pages\v2.0\Assemblies\System.Web.WebPages.dll'C:\ studyCode\MVCDemo-Part12\MVCDemo-Part12\MVCDemo\Attributes \验证\ EqualAttribute.cs 54 28 MVCDemo

我可以GET使用mux访问参数:

import (
    "github.com/gorilla/mux"
)
func main(){
     rtr := mux.NewRouter()
     rtr.HandleFunc("/logon", logonGet).Methods("GET")
}
func logonGet(w http.ResponseWriter, r *http.Request) {
    params := mux.Vars(r)
    login := params["login"]
}

但无法弄清楚如何访问 POST params

func main(){
     rtr := mux.NewRouter()
     rtr.HandleFunc("/logon", logonPost).Methods("POST")
}
func logonPost(w http.ResponseWriter, r *http.Request) {
    // how to get POST parameters from request
}
