history

I install ruby via rbenv-installer . When I use irb console, I can use history by pressing up and down on keyboard. And when I exited from console and start it again, I can't use prewious history. When I press up-arrow-button, nothing was happened. When I used rvm this option was working. How can I switch on it in rbenv? arturtr I found this way for solving my problem. In file ~/.irbrc write: require 'irb/ext/save-history' #History configuration IRB.conf[:SAVE_HISTORY] = 100 IRB.conf[:HISTORY_FILE] = "#{ENV['HOME']}/.irb-save-history" Found in this question: irb history not working Create ~/

这篇文章主要分享一下通过 HTML5 的 history API 的时候，使用 NodeJS 后端应该如何配置，来避免产生404的问题，这里是使用的express的框架，主要是通过 connect-history-api-fallback 这个中间件来实现的！ 前言 这里使用vue-router来实现的单页应用为例，访问 http://cnode.lsqy.tech ，进入首页，点击下面的tab栏，一切都是很正常的，但当这时候你 ctrl+command+R 或 点击浏览器的刷新按钮 或 在地址栏上再敲一下回车，总之就是刷新，发现就会出现404了，比如这样的错误 Cannot GET /message/ ,因为默认浏览器会认为你是在请求服务端的路由，服务端那边没有对应的处理，所以自然就会出错了，下面来引入 connect-history-api-fallback 这个中间件，来无痛使用优雅的History路由模式。 引入connect-history-api-fallback 首先看它的介绍 Middleware to proxy requests through a specified index page, useful for **Single Page Applications** that utilise the HTML5 History API.

看见bug惊讶，代码中并没有require(“history/createBrowserHistory”) //原有代码为 import createBrowserHistory from "history/createBrowserHistory"; const customHistory = createBrowserHistory(); bug解决方式为 import {createBrowserHistory} from 'history' const customHistory = createBrowserHistory(); 本文借鉴自： https://stackoverflow.com/questions/55466802/react-requirehistory-createbrowserhistory-instead-of-requirehistory-crea 来源： https://www.cnblogs.com/smart-girl/p/11427746.html

I am designing this database that must maintain a history of employee salary and the movements within the organization. Basically, my design has 3 tables (I mean, there more tables but for this question I'll mention 3, so bear with me). Employee table (containing the most current salary, position data, etc), SalaryHistory table (salary, date, reason, etc.) and MovementHistory(Title, Dept., comments). I'll be using Linq to Sql, so what I was thinking is that every time employee data is updated, the old values will be copied to their respective history tables. Is this a good approach? Should I

修改历史（Change-History）宏显示了页面一个的更新历史：版本号，作者，日期和备注。这些内容将会在同一栏中进行显示。 屏幕截图：Confluence 中的修改历史（Change-History）宏 为了向页面中插入修改历史宏： 从编辑工具栏中，选择 插入（ Insert ） > 其他宏（Other Macros） 找到并且选择需要的宏。 可用使用自动完成加快这个过程： 输入 { 然后开始输入你希望插入的宏的名字，你将会看到建议的宏的列表。在这个列表中，我们插入 cheese 宏（cheese macro）。 如果需要对已经存在的宏进行编辑： 单击宏的占位符，然后选择 编辑（Edit） 。这将打开宏的细节，你可以对宏的参数进行编辑。 注意： 这个宏没有参数 Wiki markup example 宏名称： change-history 宏内容： None {change-history} https://www.cwiki.us/display/CONF6ZH/Change-History+Macro 来源： https://www.cnblogs.com/huyuchengus/p/11427511.html

I am currently playing around with the idea of having history tables for some of my tables in my database. Basically I have the main table and a copy of that table with a modified date and an action column to store what action was preformed eg Update,Delete and Insert. So far I can think of three different places that you can do the history table work. Triggers on the main table for update, insert and delete. (Database) Stored procedures. (Database) Application layer. (Application) My main question is, what are the pros, cons and gotchas of doing the work in each of these layers. One advantage

(When I say STL, I'm talking about the template library that revolves around containers, iterators, algorithms and functors.) This question came to mind after thinking that a std::string mostly behaves like a normal container, with begin and end functions (including iterator), a size function and the possibility to use all of those for normal STL algorithms that work on containers / ranges through their iterators (e.g. transform , sort , find , etc.). At the same time, however, it is not a container itself, as it doesn't fit in picture of containers that store arbitary data. Also, it operates
