Debian和Ubuntu开发人员Julian Andres Klode今天报道，Canonical计划在Ubuntu Linux操作系统的未来版本中默认实现Facebook的zstd压缩算法。
zstd是一种开源无损数据压缩算法，由Facebook的Yann Collet开发，旨在提供快速的实时压缩和解压缩速度，甚至比xz或gzip更快。 Zstd支持多达19个压缩等级，提供2.877的压缩比，高达430 MB/s的压缩率和1110 MB/s的解压缩速度。
Julian Andres Klode和Balint Reczey报告说，他们设法将标准Ubuntu 18.04 LTS（Bionic Beaver）64位安装的速度提高了10％，zstd配置设置为最高级别19级。更好的是，当“eatmydata”库设计用于禁用fsync和相关包时，安装速度提高了大约40%。
“在我们的配置中，我们运行zstd在第19级。对于amd64版Ubuntu 18.04，它的大小增加了大约6%，从大约5.6到5.9GB。安装速度提高约10%，或者，如果涉及到eatmydata，最多可达40%的用户时间，一般约为50%，”Julian Andres Klode在邮件列表声明中说。
在Ubuntu 18.10中默认启用Zstd
在Debian GNU/Linux和Ubuntu操作系统的dpkg和apt命令行软件包管理系统中实现了对Facebook的zstd压缩算法的支持。此外，Canonical现在计划在未来的Ubuntu版本中默认启用它，从今年秋季的Ubuntu 18.10开始，据报道zstd将安装大小增加了大约6％。
Zstd也将在即将发布的Ubuntu 18.04 LTS（Bionic Beaver）操作系统中提供支持，该系统将于2018年4月26日发布。两位开发人员表示，他们对dpkg和apt的zstd实现能够支持多个框架，这意味着Debian软件包最终将被并行地压缩和分解。
谁知道怎么用LINUX系统？
我不想粗口骂人!这类回复浪费位置Linux的学习可以到国内有名的Linux站点学习,或是使用的Linux版本建的交流平台学习Linux的学习无非是多用多想多记没有捷径的.记好命令最好,不能记就用X界面的当前最流行的ubuntu界面做得不错,软件的问题也解决得很好,官方交流平台也有不错的回复和Wiki
截止到2008年8月avast!杀毒软件究竟拿过多少个vb100奖呢？
卡巴斯基 就是卡的死机 为什么卡巴斯基 扫描慢! 因为卡巴斯基病毒库大! 为什么avast容易误杀! 因为avast预防未知病毒! 卡巴斯基的确相对不容易误杀!因为 他基本上不怎么对未知病毒进行查杀. 但是这群人很努力,一有新病毒被反映上来,立刻就会对其进行处理然后更新! 所以卡巴 是后知后觉 亡羊补牢型的 当然好多人都会抱着侥幸 我不会第一时间去中流行病毒 还有好多人在前面顶着! 熊猫烧香!其实并不厉害,好多病毒跟他也没啥差别.为啥他这么吊! 因为作者很厉害,以前好多病毒做出来就跟没娘的孩子一样,没人管了. 而他很牛,做出来后一直更新,一直保持走在杀毒软件病毒库更新的前沿! 你卡巴什么的刚更新个这种病毒,第二版本就出来,在第一版的引导下走进你的电脑,电脑受虐了,等大功告成发现能杀的时候.已经N版出来了,然后满屏幕就是熊猫了! 而你用avast吧,这毒 根本进不来. avast的确误杀很厉害!但是其实都是有道理的!因为好多软件的确是有病毒 的特征,国内的好多软件防破解自己加点什么东西,加个壳什么的 或是大家好多用的是破解软件,破解程序是最接近病毒的. 有些破解程序,甚至于就是病毒! 但说归说,他的误杀 还是造成了我很多不便,最近瑞星免费就去用了 很怀念以前自己是超级菜鸟什么都不管,一星期杀一次毒的日子, 但是现在稍微知道那么一点点,反而天天心惊胆战, 算了,还是avast吧! 瑞星太不保险了! 同样当时卡巴就是比瑞星吊那么点,但也是比瑞星要误杀好多, 毕竟瑞星是本土产品,还是比较了解本土特性误杀较少! 但是大家为啥都说卡巴好! avast也是这样,在最新病毒问世后avast能70%免疫,卡巴也许就20%吧! 不用怀疑 你的选择 avast 就是世界顶尖的杀毒软件! Alwil 历届 VB100 测试结果 虽然也有好多没过的 时候但大多是在以前 而且 可以找别的测试结果对比 发现 还是很牛的!(瑞星好像今年刚通过一次?) vb100仅是测试 还得看用的! —————————————————————————————— VB100 Results Overview: Alwil 26 Success / 22 Failure / 11 No Entry —————————————————————————————— August 2008 - Alwil avast!Status: PASS Product name: Alwil avast!

谁帮我解释解释LINUX和UNIX是什么一个概念？！
Linux、Unix只是个内核，你不能直接用的。 Mac os x用的是unix内核，linux的就多了（像ubuntu、redhat)。 真正人性化的是unix的mac os x ,不代表所有unix都人性化。 说到人性化，linux连windows都不如。 而且除了mac os x ，多数基于linux、unix的系统一般都不用于个人桌面，服务器才是它们的强项。 Mac os x 10.6截图：（自己看去。 。 挺美吧。 。 )hat linux （惨不忍睹。 。 建议不要看）ubuntu 10 :
