重要通知，更换域名。 由于google domains要关闭，所有域名资产卖给squarespace。所以要把域名迁移出去。当在迁移过程中才发现，ooo域名不好找商家来转移。cf没有此域名的注册和转移，亚马逊云也没有，其他一些知名的注册商也没有此域名的注册和转移。可能与ooo域名是印度注册局提供的，在美国注册商中，很少提供此域名的注册。 经过几天的迁移，about.ooo更换为about.cam域名。所有的数据和注册没有任何变化。about.ooo将为个人使用。欢迎使用about.cam继续访问。 »
2009年，因为域名到期，数据丢失，微信息和SNS的层出不穷，就再也没有写过log和打算继续写log的打算。最近整理数据，记起了很多往事。sablog的开发者小A曾经在log里挂出一句话：人的头脑太复杂，时间过得久，有时候连自己也被自己骗了，记下来才是最真实的。 2015年左右，就有开发者用kindle来阅读RSS了。我也是在那时候开始使用kindle来阅读RSS的。算起来也使用很多年了。 站在2021年，使用这样的服务来阅读，可以更加专注。这个服务是按年收费的。也非常感谢开发者送给我了一个终身会员的服务。所以今天我就重新介绍一下这个服务。 作者是一个RSS迷和kindle迷，在之前就做过RSS推送到kindle的服务，我那个时候购买过这个服务，结果推送并不是实时的，再加上推送内容有时候无法全部抓取，用kindle阅读RSS还是很费劲。当时跟作者聊天，发现他对kindle的使用很极客。 最让我想象不到的是，在kindle的浏览器基本上不能用的情况下，作者做出了Reabble.com（如果您在大陆请使用reabble.cn域名访问）这个服务。要在 Reabble 上开始浏览 RSS，你需要使用你的 Inoreader 帐号来登陆就行了。使用 Inoreader 成功登陆 Reabble 后，你就可以立即开始在舒适的电子墨水屏幕上阅读 RSS 了。当然，你的已读与未读，还有收藏的文章都是同步的，毕竟这是一个在线服务。比推送要强多了。 你是知道，Kindle 的电子墨水屏幕刷新缓慢，你要用它来拖动查看网页真是不能忍。因此，Reabble 为 Kindle 的操作体验进行了优化，在 R... »
You’re six months into a project when you realize a tiny, simple assumption you made at the start was completely wrong. And now you need to fix the problem while keeping the existing system running—with far more effort than it would’ve taken if you’d just gotten it right in the first place. Today I’d like to tell you about one common mistake, a single word that will cause you endless trouble. I am speaking, of course, about “users”. There are two basic problems with this word: “User” is almost never a good description of your requirements. “User” encourages a fundamental security design flaw. The concept “user” is dangerously vague, and you will almost always be better off using more accurat... »
It makes sense that founders and investors spend so much time talking about things that go well. If we spent all of our time dwelling on the companies that failed, we wouldn’t have time for much else. When people do talk about company failure, they often do so in a way meant to make them seem wise by breaking down all the lessons they’d learned through failing. I did something like this when we shut Tutorspree down. I think that was a valuable exercise, and maybe it even helped some people. Mostly, though, it was cathartic. Founders lack a coherent way to think about when to shut down.1 Founders do not always get to choose to shut down.2 However, most of the time, it is the founder... »
There are about 5.5bn adults on earth; 5bn now have a mobile phone, 3.5-4bn have a smartphone, and 800m of those smartphones are iPhones. We connected the Earth, and Apple did pretty well out of that. The trouble is that once you connect all the people, there are, well, no more people, and growth becomes a challenge. So smartphone sales are flat-to-down year on year, Chinese smartphones sales are down and iPhone sales do not have as much growth ahead as they had in the past. Boring. What next? There are two conversations for Apple here. The first is that, just as when the iPod was The Thing and people wondered what was next, Apple has Projects. For example, some sort of car project has been ... »
