区块链扩容一直是区块链团队的重点研究方向.因为比特币对区块大小的设定是固定的,而且中本聪将最初大小值限定为1M,但随着交易量的增加,网络拥堵情况也愈渐严重,最终也导致了比特币的分叉. 区别于比特币固定区块大小的设定,以太坊则引入了燃料(gas)的概念,并采取了区块燃料限制(Block Gas Limit)动态调整机制,即根据交易量大小来调节Block Gas Limit.通常我们以TPS来衡量区块链的交易处理能力, Block Gas Limit值越大则意味着允许区块打包的交易量也就越多,也就是

There are N gas stations along a circular route, where the amount of gas at station i is gas[i]. You have a car with an unlimited gas tank and it costs cost[i] of gas to travel from station i to its next station (i+1). You begin the journey with an e

A gas station has to be built at such a location that the minimum distance between the station and any of the residential housing is as far away as possible. However it must guarantee that all the houses are in its service range. Now given the map of

这段时间在做公司APP的项目,看到公司开发IOS的同事和我这边联调程序时,经常需要手动修改hosts文件,比较麻烦. 在公司忙,没有来及找,给同事推荐了我当时知道的一个切换hosts文件的工具:smarthosts,感觉还是麻烦. 晚上下班回来又找了下,发现一个mac下更好的修改hosts工具——Gas Mask. 这个工具跟我windows下的Switch Hosts非常类似. 也是可以配置不同的方案,很方便的切换到不同的开发环境. 使用方法很简单,我截个图说明用法. 默认切换后,会在桌面右上

面对成百上千的生产系统用户操作数据接入落地,你是否厌倦了每次机械编写打包解包的代码?对一次性接入多个数据的时候,还要对不同人联调,费时费力,你是否还会手忙脚乱,忙中不断出错?是否当数据出问题了,用的时候才发现,数据已经损失大半,产品/领导压力巨大,费一天劲才能定位问题,关键是下次还是不能实时发现,快速定位. 怎么办?GAS(通用解析服务)就是为了解决上述问题,结合即通多年数据方案实践,提出的一个数据接入的组件.一杯清茶,轻点鼠标,轻松面对大批数据接入问题. GAS在ADs中的位置 图 1  AD

留个爪,稍后学习 选择编译器nasm?fasm?yasm?还是masm.gas或其他? 前面三个是免费开源的汇编编译器,总体上来讲都使用Intel的语法.yasm是在nasm的基础上开发的,与nasm同宗.由于使用了相同的语法,因此nasm的代码可以直接用yasm来编译. yasm虽然更新较慢,但对nasm一些不合理的地方进行了改良.从这个角度来看,yasm比nasm更优秀些,而nasm更新快,能支持更新的指令集.在Windows平台上,fasm是另一个不错的选择,平台支持比较好,可以直接用来开
