Google Bookmarks要关闭

Google Bookmarks要关闭

自从Chrome有了书签功能以后,Google Bookmarks基本上处于没有人维护的状态。持续了好多年,终于还是要关闭掉。其实我使用Google Bookmarks的频率是非常高的,基本上每天都要使用,收藏了好多书签。 Google Bookmarks关闭以后,没有办法只能自己搭建一个使用。现在在线书签功能基本上都停止了。可能是,已经很少人会收藏网络地址,更多的是使用APP来浏览来发现。 很多习惯,我还是从电脑那个时代保留了下来。 »

Dmarc邮件安全协议

Dmarc邮件安全协议

最近在设置dmarc,设置完成以后,发现安全性还是有很大提升的。 2012年1月30号,由Paypal,Google,微软,雅虎,ReturnPath等15家行业巨头(主要包括 金融机构,Email服务提供商,数据分析机构等)联手宣布成立了新的互联网联盟,致力于提交并推广一款[DMARC]新电子邮件安全协议。 设置DMARC记录,防止他人伪造贵司域名,还可以获取到他人尝试伪造贵司域名的情况。 当Mail Receiver方(其MTA需支持DMARC协议)收到该域发送过来的邮件时,则进行DMARC校验,若校验失败会发送一封report到DMARC设置的邮箱。 我设置了邮箱基本上每天都会发一封或者多封邮件,dmarc报告。我查询到,原来好多公司会雇佣单独的公司来分析这些报告。 当然设置dmarc一个基本前提是设置了spf。 这是dmarc组织的官方地址 https://dmarc.org 下面是我收到的report报告。 »

Never use the word “User” in your code

Never use the word “User” in your code

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... »

On Shutting Down

On Shutting Down

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... »

Apple as the new Disney

Apple as the new Disney

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 ... »
