Efficacy of combinging reset and base, instead of building one off the other

浪子不回头ぞ 提交于 2019-12-10 21:23:33
问题 Recently I've taken to combining reset and base into one nefarious optimized streamlined smorgasbord. I'm finding it to be a real treat, and wonder if this is common practice. My guess is "no"...and "yes"... That is, I'm under the impression that some programmers get annoyed with reset and like to do everything from scratch. Others like the convenience of a baseline, but they do it first with a reset.css stylesheet, followed with a stylized base.css My new approach has them combined. One

Connection reset原因分析和解决方案

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 在使用HttpClient调用后台resetful服务时, “Connection reset”是一个比较常见的问题,有同学跟我私信说被这个问题困扰很久了,今天就来分析下,希望能帮到大家。例如我们线上的网关日志就会抛该错误: 从日志中可以看到是Socket套接字在read数据时抛出了该错误。 导致“Connection reset”的原因是服务器端因为某种原因关闭了Connection,而客户端依然在读写数据,此时服务器会返回复位标志“RST”,然后此时客户端就会提示“java.net.SocketException: Connection reset”。 可能有同学对复位标志“RST”还不太了解,这里简单解释一下: TCP建立连接时需要三次握手,在释放连接需要四次挥手;例如三次握手的过程如下: 第一次握手:客户端发送syn包(syn=j)到服务器,并进入SYN_SENT状态,等待服务器确认; 第二次握手:服务器收到syn包,并会确认客户的SYN(ack=j+1),同时自己也发送一个SYN包(syn=k),即SYN+ACK包,此时服务器进入SYN_RECV状态; 第三次握手:客户端收到服务器的SYN+ACK包,向服务器发送确认包ACK(ack=k+1),此包发送完毕,客户端和服务器进入ESTABLISHED

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Io 异常: Connection reset by peer: socket write error Connection reset by peer的原因: 经常出现的Connection reset by peer: 原因可能是多方面的,不过更常见的原因是: ①:服务器的并发连接数超过了其承载量,服务器会将其中一些连接Down掉; ②:客户关掉了浏览器,而服务器还在给客户端发送数据; ③:浏览器端按了Stop 来源: oschina 链接: https://my.oschina.net/u/203585/blog/168585

Why is there the need for browser resets?

给你一囗甜甜゛ 提交于 2019-12-10 18:14:00
问题 Okay that's probably not the best title, I know why we need browser resets: because browsers have different defaults set. My question that was too long to put into a title is: If everyone needs to use a reset stylesheet 90% of the time, why do browsers need to set default styles? We're just going to remove them anyways, right? 回答1: Because certain rules make sense by default: Table cells have display:table-cell; <b> makes text bold, <i> makes text italic Paragraphs should have space in

Git的基本概念和用法

丶灬走出姿态 提交于 2019-12-10 17:40:07
在日常使用GIT过程中,经常会出错,比如无意间丢失了未提交的数据,回退版本时丢失了工作目录,等等。经过思考发现,所有这些错误都是因为对GIT中一些基本的概念模糊而导致,因为对一些基本概念不清晰,导致对GIT每一条命令将会产生的结果不符合预期。下面我就梳理以下我经常碰到的问题相关的基本概念。 1. Working Directory(工作目录) Git的工作目录是保存当前正在工作的文件所在的目录,和working tree是相同的意思。在这个目录中的文件可能会在切换branch时被GIT删除或者替换。这个目录是个临时目录,临时存储你从GIT库中取出的文件,这些文件一直会被保存,直到下次提交。 2. GIT Directory(GIT库目录) 项目的所有历史提交都被保存在了GIT库目录中,只要你不作回滚操作,它应该不会丢失。 3. GIT Index(Git索引) Git index 可以看作是工作目录和Git库目录之间的暂存区,和staging area是相同的意思。可以使用Git index构建一组你准备一起提交的改变。Git Index和Git Staging area是同一个意思,都是指已经被add的但尚未commit的那些内容所在的区域。最简单的查看目前什么内容在index中的方法是使用 git status 命令。 命令中”Changes to be committed

Why not reset CSS using the asterisk? [duplicate]

烈酒焚心 提交于 2019-12-10 15:48:29
问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: (why) is the CSS star selector considered harmful? I noticed that many CSS developers reset the margin, font and padding of a big number of HTML elements by explicitly declaring them all in the beginning (e.g.Yahoo and meyerweb versions). So I ask myself, why not simple reset globally using the *? I know that this break the layout for some elements like buttons and blockquotes but those can easily be restyled,

Page refresh in case of javascript errors

时光怂恿深爱的人放手 提交于 2019-12-10 13:57:50
问题 I have some pages running javascript for displaying updates of different measure values. These stuff seems to run fine. But - there is always the risk that javascript can crash in case of a fault (especially after running some hours) So I want to implement a simple kind of watch dog. One of my ideas is to use a meta-refresh-tag. The Browser will reload the site after xy minutes and all javascripts will be reinitalized. Of course I do not want to refresh the site if no error occured and want
