Excuse me.

No problem! Thanks for pointing people to the article, I write articles with the hope that someone will read them :-).

That article is part of a series of articles called "Learning from Disaster": https://dwheeler.com/essays/learning-from-disaster.html I think we can learn from the past, and sometimes learning a story & working to gain lessons learned from it can really help.

Excuse me for changing the title of your essay. I should not do that.

The title was just my opinion. Some days ago, I read the excellent newsletter [1] of Filippo Valsorda about a Telegram's bug [2]. Yesterday, I googled for bugdoors and read about them and found this Apple's bug and your excellent essay (with many useful hyperlinks) about it.

Thank you so much!

This was obviously a merge error.

I think that's very likely, but I've never seen a post mortum from Apple where they track down what happened.

I wish they would be more open about what happened. Mistakes happen. It's better for the industry if we can all learn from them.

The problem of censorship on Twitter and other social media can be solved with a good moderator like dang (thank you!)

Thanks for sharing this class.

The best references to learn Unix (and TCP/IP and networking) are still William Rich Stevens books.

No PR!

FB uses Subversion!

Signal is my choice for its security, but Telegram has an advantage: it is more user friendly.

Or what made Bell labs so special?

Happy new year!

Me too.
