来了小伙伴们，周末又快结束了，这两天没啥大事，咱们就轻捋一下值得说的一二三。 1、川普正式接受共和党的总统候选人提名。他接受媒体采访时阐述了自己的一些执政思路，首先是上任就会取消电动车补贴。可能有些读者会困惑，不 是听说马斯克全力支持吗，这样对特斯拉是否不利？是这样的，美国电动车不止特斯拉一家，符合补贴条件的车企不少，马斯克之前就反对全行业的补 贴，他认为取消补贴的话特斯拉会更轻易的卷死同行，以获得更大的市场份额。 另外川普计划大力发展石油工业，生产更多的石油来降低油价，降低通胀，带动传统汽车工业，提供更多美国国内就业岗位。 那么环保怎么说？去tm的环保。 其实每个国家根据自己的禀赋来发展工业也是个思路，中国是个贫油国家，全力all in电车是弯道超车的机会。美国能源丰富，选择滞留在自己的舒适区 也ok。作为参考，最新的油价是中国比美国贵了25%-30%，这还没考虑对岸人均收入比咱们高了将近6倍。 2、周五的微软蓝屏事件影响了大约850万台电脑，占了使用微软系统电脑的1%左右。这个我前天的文章里解释了，起因是crowdstrike软件升级所致， corwdstrike是一款主要针对企业端的高级安全系统软件，价 ...

今天全世界的焦点是微软蓝屏事件。 今天白天，全世界大量使用微软系统的电脑出现了蓝屏故障，一时间很多公司被迫停工，好几个航空公 司紧急中断所有服务，多家世界连锁超市停止收付款，人们意识到微软系统已经成为人类文明的基建， 一旦离开它很多社会活动都会被迫停止。 我买微软股票已经有六七年了，是信奉长期价值的股东，看到这件事后第一时间也有些慌，担心是一起 重大的技术事故，就去查询了一下相关信息。 原来这次全世界大范围的蓝屏是因为crowdstrike软件引起的，这是一家安全系统公司，不是微软的系统 软件，也不是预装软件，是第三方软件，只是和微软有一些业务上的合作。 这次蓝屏门是因为c rowd strike的一 次 内容部署升级 ，导致系统崩溃， 目前已经修复。 我猜大部分的读者都没怎么听说过crowdstrike这家公司，我之前也没听说过，原因是它们主要服 务企业用户，个人电脑用的不多，所以大众知名度不高。 crowdstrike的主营是安全系统，我问ai举一个通俗的例子说明它和传统杀毒软件的区别。ai说我们 的电脑是一座房子，防火墙可以理解为防盗门，杀毒软件可以理解为小区巡逻的保安，而 crowdstrike可以理 ...
