so I was either delivering presentations or burnt out for the past 8 days, and it looks like a shitton more vulns dropped besides CopyFail (which I mitigated)? go read Ti's thing, it helped me catch up on WTF was going on and what I should check in on my team with once I get back to work tomorrow.

My terminal stack for the past 10+ years was Alacritty/tmux/Fish shell. With agents becoming mainstream, I wanted to modernize the stack. After spending a few hours working in anger with Wave, configuring it, clocking how GenAI works in it, I am sold! Recommend to try yourself: www.waveterm.dev

After 7+ years, I wrapped up my gig at Amazon Web Services (AWS) on Thu 4/30. I am leaving incredibly thankful for all the things I've learned there. As an old open-source community saying goes "same team, different employer", I will continue on the Team OpenTelemetry, stay tuned. #aws #goodbye
