This problem was recently asked by Microsoft:

Given a string, find the length of the longest substring without repeating characters.

Here is an example solution in Python language. (Any language is OK to use in an interview, though we'd recommend Python as a generalist language utilized by companies like Google, Facebook, Netflix, Dropbox, Pinterest, Uber, etc.,)

132 - 儿童编程热和计算机思维的培养 - computational-thinking-for-children.txt

AI（人工智能）的潮流轰轰烈烈而来，“深度学习”的字眼处处可以见， 面向儿童的编程课也成了热门课，好多家长都愿意付费让孩子去学。

先不说这些编程课质量如何，效果如何，就随便聊聊 “学习编程要不要早早开始”？

周末跟一个英国人工智能公司的小伙子聊了一下。 他是N大物理系毕业的，现在AI领域做得相当好， 不但公司里头的项目客户包括银行律所医院学校，而且自己业余做的项目客户里头有石油大公司。 他的观察是大学里头学计算机专业的，反而被困住了，在AI项目组里头往往成为边缘人员。而物理数学专业出来的，更擅长数学模型的思考和运算，可以在更高的一个层面上去思考问题，倒是项目的核心人员。他还举例说，90年代出国的好些华人其实都是数学很强的，可大多为了生计，转做码工，专职编程。现在AI热浪来了， 要转过来就觉得很吃力了。

142 - Linode Support Ticket 10029540 - Other - Important Notice Regarding Ubuntu 17.10 Image - linode-ubuntu17.10-man-in-the-middle-attack.txt

We recently identified an issue with our Ubuntu 17.10 image which resulted in Linodes being created with the same SSH host keys. As a result of this, it is possible that an attacker could launch a man-in-the-middle (MITM) attack on your SSH sessions.

Any Ubuntu 17.10 Linode which was created between January 11 and February 22 is affected (other versions of Ubuntu are not affected). In addition to Linodes that were deployed during this time frame, images and backups that were taken of an affected system would also continue to have this issue present.

We recommend that you regenerate new SSH host keys using the procedure below as soon as possible to avoid the risk of a MITM attack.

参数式的URL的坏处

原来就是比较恶心的 ?a=b&c=d&e=f 的形式。这种方式不会被搜索引擎认为是好的URL形式，参数关键字不会被采纳：如上面a, b, c 和 d 是都不会被索引的。别一坏处就是 URL变得过长，且不容易理解。
