究竟你适不适合买Mac?
我清晰的记得,刚买的macbook pro回到家,开机后第一件事情,就是上了淘宝网,花了500元钱,找了一个上门维修电脑的师傅,上门给我装了一个windows系统。。。。。。 表砍我。。。 当时买mac的初衷,只是想要个固态硬盘的笔记本,用来运行一些复杂的扑克软件。而看了当时所有的SSD笔记本后,最终决定,还是买个好(xiong)看(da)的。 已经有好几个朋友问我mba怎么样了,所以今天尽量客观...

程序员一般通过什么途径接私活?
二哥,你好,我想知道一般程序猿都如何接私活,我也想接,能告诉我一些方法吗? 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”,还有很多读者问过我类似这样的问题。 我接的私活不算多,挣到的钱也没有多少,加起来不到 20W。说实话,这个数目说出来我是有点心虚的,毕竟太少了,大家轻喷。但我想,恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉,我也算是有经验的人了。 唾弃接私活、做外...

Python爬虫精简步骤1 获取数据
爬虫,从本质上来说,就是利用程序在网上拿到对我们有价值的数据。 爬虫能做很多事,能做商业分析,也能做生活助手,比如:分析北京近两年二手房成交均价是多少?广州的Python工程师平均薪资是多少?北京哪家餐厅粤菜最好吃?等等。 这是个人利用爬虫所做到的事情,而公司,同样可以利用爬虫来实现巨大的商业价值。比如你所熟悉的搜索引擎——百度和谷歌,它们的核心技术之一也是爬虫,而且是超级爬虫。 从搜索巨头到人工...
