Now is a good time to get started with local AI, no matter if from an individual POV or in the context of regulated business (health care, FinTech, etc.). WDYT? #genai #localai #llm

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

reading @norootcause.surfingcomplexity.com this morning to me, observability has always been the answer to “how do we move towards safety-II culture” but the myopic focus on big chungus json search and dashboards has crippled this transformation surfingcomplexity.blog/2026/04/26/t...

Thank you Bloomberg engineering for stepping up here, would love to see other companies do this with open source projects "Sustaining OpenTelemetry: Moving from dependency management to stewardship" www.cncf.io/blog/2026/03...

AWS just shipped native OpenTelemetry metrics support in CloudWatch. This one got buried under the S3 Files announcement, but it deserves more attention!
