为什么 Windows 系统 Program Files 这个经常用来装软件的目录，名称中有个空格？[抠鼻]

设计上的失误而已。

最初这么设计是为了让这个目录显示起来更自然。有空格的原因在于英语母语国家阅读单词就是应该有空格的。

然而现在大家都知道了，对「显示友好」这个问题业界其实有更标准的做法，就是「将显示名称跟真实名称隔离」。

目前的Windows用户目录，子目录，以及Linux跟MacOSX的设计都是这样做的。也成为标准做法。它们的真实名称永远是一个更方便键盘输入的简单名称，而显示名称可以很复杂，可以多国语言本地化翻译，当然也可以带空格。

但是在当时，微软没有想出这个设计。于是做出了 Program Files 这个坑。结果这个原本用于安装软件的目录，因为一部分软件拒绝安装到带空格的目录而被迫安装到其他地方，也就是说这个设计反而阻止了应用程序安装进去。

虽然一部分玩家会想办法为这个问题洗地，但微软已经用自己的行为向世人证明了这确实是一个失误：因为后来微软设计了很多目录，例如ProgramData, AppData 等目录，全都不带空格。微软自那一批之后，再也没有设计出带空格的系统目录，显然是微软已经意识到了这么做是错的。

而 Program Files 这个历史问题，已经积重难返，微软或许只是因为兼容性而不得不保留了它。

你们觉得呢？

#乌克兰：或在顿巴斯爆发大规模冲突#那个地方前几年开始就是在正式的打仗了。从伤亡人口来说，早就已经在“战争”了。

按照Uppsala Conflict Data Program的定义标准，一年之内死亡1000人以上的冲突就是战争。乌克兰东部早就死亡过万了。

#俄乌军力孰强孰弱 边界冲突会升级吗# 头条热榜

¹现在全世界都在看着俄罗斯，看看俄罗斯会不会对乌克兰发动真正的战争。这里需要给大家科普一下，在国际政治学里面“战争”到底指的什么意思。以及过去这些年俄罗斯和乌克兰的冲突算不算已经构成“战争”。

²给大家报告一个数字，乌克兰顿涅茨克地区的“战争”早在2019年就死亡13000人。而按照Uppsala Conflict Data Program的定义标准，一年之内死亡1000人以上的冲突就是战争。这个地区是要脱离乌克兰加入俄罗斯的。

所以显然，乌克兰和俄罗斯之间的冲突，至少在伤亡人数上早就已经达到了战争的规模。现在的问题就是会不会演变成一场常规意义上的地面战争。

Windows环境下启动MYSQL报错：某些服务在未由其他服务或程序使用时将自动停止#数据库##MySQL#

首先，你需要把原来的服务删除 ```mysqld --remove mysql

在mysql的根目录下， 清空data目录（如果没有data目录，请自行创建一个空目录，起名为data！）

接着执行如下命令：``` mysqld --install mysql --defaults-file=C:\Program Files\MySQL\my.ini

以管理员的身份执行启动服务命令：```net start mysql57

Regardless of the cost, you can be sure that EJA’s spending on safety will be whatever is needed. Obviously, we would follow this policy under any circumstances, but there’s some self-interest here as well: I, my wife, my children, my sisters, my 94-year-old aunt, all but one of our directors, and at least nine Berkshire managers regularly fly in the NetJets program. Given that cargo, I applaud Rich’s insistence on unusually high amounts of pilot training (an average of 23 days a year). In addition, our pilots cement their skills by flying 800 or so hours a year. Finally, each flies only one model of aircraft, which means our crews do no switching around among planes with different cockpit and flight characteristics.

EJA’s business continues to be constrained by the availability of new aircraft. Still, our customers will take delivery of more than 50 new jets in 2001, 7% of world output. We are confident we will remain the world leader in fractional ownership, in respect to number of planes flying, quality of service, and standards of safety.

Additional information about our various businesses is given on pages 42-58, where you will also find our segment earnings reported on a GAAP basis. In addition, on pages 67-73, we have rearranged Berkshire’s financial data into four segments on a non-GAAP basis, a presentation that corresponds to the way Charlie and I think about the company.
