雷军写代码水平如何? 第1页

我记得好像是13年的时候?阿黎整了个小米网的讨论会。大意是各部门把过去一年里,自己觉得做的好的、和做的烂的,摆出来。

例如设计,梁师傅就整了个两个图,一好一坏对比批判一番。

到代码那块,我记得好像是海洲来讲。坏的就是整个小米网,因为他觉得小米网的代码他还是不满意,还是要一边开车一边修车。

好的,就是雷老大的一段代码,说是二十年前的。

那段代码就那么直接投影到大屏幕上,程序员弟兄们沉默一会,然后纷纷点头。

海洲发言,大意是:我不指望你们有这水平,但你们得朝这个方向努力啊!

事后我问一位程序员老铁:你们是拍马屁还是真服?我只会Hello world,看不懂。

这位后来也做了某上市公司CTO的未来大佬对我这个文科生不屑一顾:我没法和你解释。总之,雷老大写得很简练、很清晰、很干脆,这就是牛逼,而且是高层次的牛逼。

所以我觉得,应该是真牛逼。

下面请欣赏雷总1994年写的代码片段——

这段用x86汇编写成的代码(以上是代码片段)用于清除内存驻留程序,类似内存加速工具,雷军教科书般规范地注明了代码用意、时间、作者……还细腻地用符号组成了分隔符让代码更加优雅,读起来清晰、舒适,所以雷总称之为诗一般的代码其实也不算过分。

在B站2020年6月份的一个访谈直播活动中,雷总也在给后辈的寄语中不断强调代码要整洁,逻辑要无懈可击,自己写的代码要达到例程(示范程序)的程度。这一点和《代码整洁之道》的作者Bob大叔英雄所见略同了。

Bob大叔就在《代码整洁之道》提出一种观点:代码质量与其整洁度成正比

优秀的系统往往有优秀的结构设计,层次清晰,职责单一,模块化,方便拓展和复用。功能的添加往往只是在现有的框架中添加少量代码。而且Bob大叔在《代码整洁之道》中给了我们一些行之有效的规则,涵盖从命名到重构的多个方面,只要遵循这些规则,就能编写出干净的、让人舒服的代码。

详见回答——

希望有一天,大家的代码都能“像诗一样优雅”!

最后,推荐一本阿里P8大佬撰写的算法笔记,刷完应该是超过雷军了

雷军22年前写的汇编代码,大家看看牛不牛:

电脑和编程是雷军人生中最大的兴趣,关于电脑和编程,雷军是这么说的:

程序员活在自己想象的王国里!
我刚接触电脑就发现电脑的妙处,电脑远没有人那么复杂。
如果你的程序写得好,你就可以和电脑处好关系,就可以指挥电脑干你想干的事。
这个时候你是十足的主宰。
每每你坐在电脑面前,你就是在你的王国里巡行,这样的日子简直就是天堂般的日子。
电脑里的世界很大,编程人是活在自己想象的王国里。
你可以想象到电脑里细微到每一个字节、每一个比特的东西。
我爱编程这个工作,可以肯定我会干上一辈子

正是因为热爱,所以雷军一干就是10多年。

雷军认为编程是技术,也是一种艺术,程序员需要有类似艺术家对艺术一般的追求,才能真正打造出好的产品!

雷军的技术为什么这么牛逼?他在一次采访中说过一段话:我尤其喜欢阅读计算机经典书籍,那是一种如饥似渴的感觉!

另外我把大学和工作中用的经典电子书库(包含数据结构、操作系统、C++/C、网络经典、前端编程经典、Java相关、程序员认知、职场发展)、面试找工作的资料汇总都打包放在这了,这套资源可不是一般那种网上找的资源,是伴随我从学生一路成长为腾讯高级开发工程师,360技术经理、360技术总监、中小公司CTO的打包全套,非常宝贵!点击下方链接直达获取:

点击下方链接直接获取:

雷军20年前写过一篇文章:《我会当一辈子程序员》。

看完你会知道,编程在雷军的眼里是什么样子。

有的人学习编程技术,是把高级程序员做为追求的目标,甚至是终身的奋斗目标。
后来参与了真正的商品化软件开发后,反而困惑了,茫然了。
一个人只要有韧性和灵性,有机会接触并学习电脑的编程技术,就会成为一个不错的程序员。
刚开始写程序,这时候学得多的人写的好,到了后来,大家都上了一个层次。
谁写的好只取决于这个人是否细心、有韧性、有灵性。掌握多一点或少一点,很快就能补上。
成为一个高级程序员并不是件困难的事。
当我上学的时候,高级程序员也曾是我的目标,我希望我的技术能得到别人的承认。
后来发现无论多么高级的程序员都没用。
关键是你是否能够出想法出产品,你的劳动是否能被社会承认,能为社会创造财富。
成为高级程序员绝对不是追求的目标。
编程不仅仅是技术,还是艺术。
有人认为编程是一种熟练工种,也有人把编程说成是艺术创作。这两种意见争论比较激烈。
我们换个工种来看,石匠应该是熟练工种,属于工人,更和艺术似乎沾不上边。
但正是这些石匠,给我们留下多少文物古迹,如乐山大佛、莫高窟等等。
应该说这些石匠给我们留下了无穷的文化财产。
现代软件工业已具相当规模,很多软件的完成需要的是大兵团作战。
一名普通程序员接受编写某一模块的任务后,往往只是写代码,发挥的余地很小。
在大项目中,很多程序员只能了解到和自己所编模块相关的很局部的细节。
另外还受到开发环境的限制,真的很难体会到自己在从事”艺术”创造,更多的时候是感到自己在从事重体力劳动。
有的时候还担心自己苦苦参与的这个项目究竟有没有意义,是不是在同类产品中有竞争力,会不会开发出来以后就因为硬件的发展,操作系统的换代而过时……
我认为编程的工作和石匠比较相似,有技术活,更多的是体力活。
不管怎么说,写出一个好软件不是一件容易的事。
这两种想法都有片面性,编程应该说两种属性都有。
编程不仅仅是技术,也还是艺术。编程是技术活,才有可能大规模进行,才会有软件工程和软件工厂。
也正是编程是艺术,才会有如此多的好产品,让大家如痴如醉。

关于雷军的代码水平,他自己也说过:

另外,程序员多刷算法题好处多多,想要跟雷军一样长期在编程世界里遨游,先精通算法简直是必须的,算法厉害的人进大厂非常容易,再次推荐这本阿里P8大佬撰写的Leetcode刷题笔记,它帮助我身边不少朋友加入大厂:

祝大家前程似锦,在编码的道路上一马平川。

看看这本书的目录和排版!相当经典!

PS:感谢大家的阅读,觉得不错双击点赞下呀,这里也送大家一套我花1个月时间整理的超级硬核书单,总计200本书籍,希望对大家有用:

点个赞,一键三连呗,硬核码字不易。

雷军的优秀是毋庸置疑的,在武汉大学,他两年学完计算机系四年的课程,大二就完成了毕业设计,汇编语言更是武大三十年以来仅有两个满分之一,大三就开始写加密软件、杀毒软件、财务软件、CAD软件等。至于老雷的代码水平,大家看看吧,

雷军当年可是黄玫瑰工作室的创始人呀,90年代左右,满大街的盗版工具软件光盘里面都是他们软件工作室开发的那些解密软件,我们当时用的很多正版软件都是用他们编的解密软件破壳的哦。

其实很多IT名人现在看起来好像只负责管理,不懂技术,其实他们中的不少人也是程序高手,除了雷军之外,还有他的老对头周鸿祎,当年可是中国第一个Windows平台上的电子邮件客户端的开发者哦,再往远处说,当年新浪创始人王志东,也是当年名满Windows 3.1的中文平台,中文之星的开发者。

所以说,不要以为他们只是通过管人管事而出名,他们自己本身也是实力超强的技术高手,才能看准技术的潮流呀。

老实说,我对穿越技术比对这个问题感兴趣多了,为什么大家那么喜欢cos呢?成天幻想着自己是托洛茨基同志,在红场上对红军战士招手吗?能赚几个毛主席啊?洗洗睡吧,cos有风险。

不是很懂现在人怎么买啥都成投资了,买车也要核算一下机会成本了,买手机也要考虑卖二手了,买游戏主机也要考虑跌价了,买游戏卡带也要考虑好不好出手了。

车是消费品啊,什么手机电脑主机卡带也都是消费品,消费品就是用来让你用,感受效用的。

你需要这个效用,它能提供这个效用,它的价格受供求关系影响最终维持在一个你愿意接受的水平,这就够了。

你要是不需要这个效用你就不买呗,如果你的城市真有良好的公共交通,确实省钱,省时间还省力,那你就别买呗。你买了难道不是你需要么?既然需要那还说什么呢。。


要我说,撸串才是一生最坏的投资,变成了肥肉你还得花时间、金钱和精力去减肥,可能还会带来未来潜在医疗成本。那为什么撸串摊子还是这么火?因为爽啊,因为它提供的效用我们确实需要啊。


所以不要干什么事都用投资思维去理解,这样会成为资本增殖的奴隶的。生产的目的是为了让人得到效用,而不是让生产进一步扩大。
