I loved the work Rusty performed so much! He started to work actively at Linux firewalling about at the same time as I became a Linux user and sysadmin, like more than 20 years ago, and I used what he made regularly and always found his work to have a sane UI to the admin: simple to use yet quite powerful stuff. In general kernel hackers are really a bunch of unicorns that are very focused on the code they are writing and the problems to solve, and I've the feeling that while in the 90s they were deeply recognized for their work, now instead in some way their work is a bit in the shadow... with much hype going into places where it's not deserved. But apparently most of them want just to code at low level, don't be annoyed, and get a salary. The essence of the old times programmer basically.

Impressed with:

"disagreed with my approach so much and so continuously that I developed a dread of reading my mail every morning: eventually I wrote a filter to send their mail to a separate mbox".

I'm very sorry to read this. In the early days of Redis this happened to me as well, there were a group of people continuously attacking me and I was horrified by the idea of reading their Twitter replies at some point. However instead of filtering them, I found (without conscious efforts, it just happened) a different solution, I became more and more sentimentally disconnected from the chats focusing solely on the actual arguments, filtering most of the tone and human-level parts. This makes me a sadder person, not able to joy or be sad for things I read on social networks for the most part, however in the pro side there is that I can read the harsh criticisms and find some value, sometimes, without being affected. Moreover, as a secondary adjustment, I no longer reply after a given point if I may start to sound attacking towards another person. This does not mean to accept everything, but just say after N replies: "we disagree but you are cool, I'll do what I think, have a nice day".

I still believe that we can stay in the tech world, not accepting what other people say if we disagree from a technical standpoint, without being assholes.
