我们买国外VPS服务器测试网络通常会用到speedtest,speedtest默认是测试到最近的节点,那么到国内速度如何呢?虽然可以指定服务器编号,但是一个个测试还是比较麻烦的,这里推荐一个脚本整合了几个国内的测试点,还是比较方便的.Superspeed已更新为SuperBench.sh,整合了teddysun 大佬的 bench.sh 脚本. 更新 新增 Virt 检测服务器类型参数,常见 openvz,kvm,独服都能检测出来 新增独服通电时间检测. 修复,speedtest 延迟飘逸,飘逸

编译virt viewer之前执行的configure命令,是没有使能usb-redir相关的功能,virt viewer是否支持usbredir是完全依赖于spice-gtk的. virt viewer对spice-gtk的依赖关系,可以从virt viewer的configure结果看出来: configure: Configuration summary configure: ===================== configure: configure:  Features: co

环境:OEL 5.7 + Oracle 10.2.0.5 RAC 如果你正在用OEL(Oracle Enterprise Linux)系统部署Oracle,那么可以使用yum安装oracle-validated包来简化主机配置的部分工作. 配置好yum本地源后,直接执行一条命令 yum install oracle-validated 检查发现它会自动做以下几件事: 1)安装oracle依赖包 2)/etc/sysctl.conf 增加oracle用户内容 3)/etc/security/lim

在第一次运行bundle install之后,生成了Gemfile.lock文件,里面记录gem的具体版本号,按照官方文档说明,以后运行bundle install就不会再依据Gemfile,而是根据lock文件来安装gem,以免在新的机器中安装的版本与lock中不同,导致gem混乱. 实际试验步骤: 1.第一次运行bundle install,lock文件中为 sqlite3 (1.3.11-x86-mingw32) 2.将Gemfile文件中的 gem 'sqlite3'   改为 gem

使用NPM(Node.js包管理工具)安装依赖时速度特别慢,为了安装Express,执行命令后两个多小时都没安装成功,最后只能取消安装,笔者20M带宽,应该不是我网络的原因,后来在网上找了好久才找到一种最佳解决办法,在安装时可以手动指定从哪个镜像服务器获取资源,我们可以使用阿里巴巴在国内的镜像服务器,命令如下: npm install -gd express --registry=http://registry.npm.taobao.org 只需要使用–registry参数指定镜像服务器地址,为
