Should we rebrand REST?

In this blogpost I argue the case for consigning the term REST API to history. In its place we should adopt the terms HTTP API and hypermedia API.

Comcast 用户在下载 Ubuntu 之后收到 DMCA 侵权通知

2021-05-28 15:56 #Ubuntu

美国电信公司 Comcast 的一位用户在 Reddit/linux 频道上透露，他通过 BT 下载了 Ubuntu 的 ISO 镜像之后收到 DMCA 侵权通知。在 DMCA 通知中，反盗版组织列举的侵权文件的哈希值为 4ba4fbf7231a3a660e86892707d25c135533a16a，而它正是 Canonical 官方 ISO 镜像 64 位 Ubuntu 20.04.2.0 LTS 的值。通过 BT 下载 Ubuntu 与侵权显然毫无关系。这起事件再次凸显了反盗版组织滥用 DMCA 通知的问题。

【全球抗疫“神话破灭” 台湾疫情怎么走到今天这地步】
台湾政府一直到多种新冠疫苗陆续受到欧美国家的批准认证之后才开始向厂商洽购，而这个时候大多数的头几批的生产量早已经被其他国家预订一空，而这些国家在疫苗研发期间可能早就已经投资研发经费，因此台湾拿到的疫苗数量非常少。

Rust binary search PR 导致 Polkadot 线上事故的缘由

知名公链波卡 (Polkadot) 5 月 24 号某个节点发生了一次比较大的线上事故(Out Of Memory)，是因为 Rust 标准库 binary search 一个优化 PR 导致的。

该PR 跑了将近一周时间的 crater 测试，也没有发现对线上 5 万多个 crate 有什么大影响。Rust 1.52 发布之后，没想到依然有人中招了，而且还是价值几十亿美金的项目。

@brson 特意发了 issue 说到这件事，但是 Rust 社区的人都认为这件事跟这个 PR 没有关系，因为 binary search 碰到多个重复的元素的时候确实是返回任意一个，文档上也说得很清楚了（所以这种情况下不会保证两个版本返回的位置一致，这也是 Polkadot 出现线上事故的原因)。

该 PR 作者(Folyd)说：

> 不管怎样，这件事给我的触动还是蛮大的。软件开发是复杂的，其本质原因在于现实生活就是复杂的。软件工程师只能尽可能规避发生这种情况的风险，但是没有办法做到万无一失吧。就像这位工程师说的我这是中了 Hyrum 定律（Google 一个叫 Hyrum 的工程师提的定律，可以理解为 API 领域的墨菲定律）。
