本文以华为云DCS for Redis版本为例,介绍Redis4.0的新功能.文章转载自华为云帮助中心. 与Redis3.x版本相比,DCS的Redis4.x以上版本,除了开源Redis增加的特性之外,还有如下大特性增强. l   创建耗时缩短 实例由虚机方式改成了物理机容器化部署,创建实例只需要8~10秒时间完成. l   性能提升 高性能版Redis4.x,操作系统使用华为自研的轻量级LibOS,单节点QPS从10w提升到30w l   节省成本 高性能版Redis4.x,实例规格以1G为步

最近使用github上的一个开源项目训练基于CNN的翻译模型,使用THEANO_FLAGS='floatX=float32,device=gpu2,lib.cnmem=1' python run_nnet.py -w data/exp1/,运行时报错,打印"The image and the kernel must have the same type. inputs(float64), kerns(float32)"的错误,然后使用THEANO_FLAGS='floatX=float

1.概述 1.1 WPF C# 命令的本质 命令是 WPF 中的输入机制,它提供的输入处理比设备输入具有更高的语义级别. 例如,在许多应用程序中都能找到的“复制”.“剪切”和“粘贴”操作就是命令. WPF 中的命令是通过实现 ICommand 接口创建的. ICommand 的 WPF 实现是 RoutedCommand 类,这是WPF C# 命令的本质. 1.2 WPF C# 命令的机制 1.2.1 编程范围 ICommand 公开两个方法(Execute 及 CanExecute)和一个事件

High Level Tips for Redis Most of Stream-Framework's users start out with Redis and eventually move to Cassandra because Redis becomes too expensive to host. Stream, our hosted API for building scalable newsfeeds & activity streams is also based on C

开发CLI工具过程中,为了便于扩展,将CLI的实现分为基础功能和扩展功能.基础功能包括init.build.lint.publish等伴随工程从初始化到最终发布到生产环境,也即为CLI 的core.扩展功能包括规范检测.代码生成.图片上传等和多个平台集成的开发配套服务设施.本篇文章将会叙述如何优雅的实现插件机制,通过插件扩展子命令和开放CLI的生态. CLI初始化流程 运行某个CLI命令时,CLI的初始化加载如下图: 第一步,判断当前用户信息,获取用户的rtx名字.然后读取cli的配置信息,包括

kbmMW的更高版本包含越来越多的功能,可用于通常的日志记录,审计,运行期发生异常时的堆栈跟踪以及现在的内存使用调试.这些功能实际上可用于任何应用程序,不仅限于基于kbmMW开发的多层应用系统.我已经在kbmMW上写了一些关于日志记录和审计系统的文章,其中还介绍了如何在处理异常时的堆栈跟踪,最近新增加的功能是能够实时跟踪应用程序的每个内存分配.你可能会问,FastMM已经内置了内存泄漏检测,为什么还用kbmMW的内存调试器呢?FastMM仅跟踪通过常规GetMem等完成的内存分配,它不跟踪通过W
