@srhtcn Thank you for your kind words, Serhat!

When you interact with @jeffbarr, you always feel like he genuinely cares. He stays in conference all day long to chat with people. Does not skip speaker dinners.. At his level and exposure, that is so rare. We are fortunate to have him this May in AWS Community Day Türkiye! 🥳🤗

@ranman Great to work with you as well, Randall!

Working with @jeffbarr and team was one of the best parts of my entire career. ❤️

@pinskinator @QuinnyPig @awsdevelopers Wow, those old posts of mine!

@QuinnyPig @awsdevelopers * SQS is the first public AWS service (TSI) * S3 is the first public AWS service to go GA (TSI) * TSI == That Still Exist, because before both was Amazon E-Commerce Service before some other thing claimed all the "ECS" URLs aws.amazon.com/blogs/aws/page…

<!-- _ .__( . )< (S3 was the first \___) public AWS service) ~~~~~~~~~~~~~~~~~~-->

We're teaming up with @cerebras to build the fastest possible inference. Coming soon to Amazon Bedrock, we’re delivering inference performance an order of magnitude faster than what’s available today by connecting AWS Trainium3 for compute-intensive prefill with Cerebras CS-3 to power decode.

@ScottSeattleWx I was on that flight a few days ago and briefly saw a ground speed of 705 MPH. Welcome back and good luck with the jet lag!

Heh Hawaiian Air flight from Tokyo to Seattle managed to ride the jet stream to a peak ground speed of 720 mph over the Pacific today :O flightaware.com/live/flight/HA…

@stmcallister This is a modern (and very nice) restatement of Amdahl's Law, which dates back to 1967.

AWS Lightsail just launched an OpenClaw template 👀 Even comes pre-configured with Amazon Bedrock - Claude Sonnet 4.6 by default! Basically a private AI assistant running in your own AWS account. What I like about this: → No external APIs handling your data

@MatthewBerman This was enlightening and amazing, and so informative. Thanks for taking the time to implement and share this!

5 BILLION tokens later, OpenClaw is now my company's operating system. I discovered things most people never will. (PS I solved the Anthropic OAuth loophole.)

Indeed, Seattle has long needed an event like this!

I had a really fun time doing this interview live from my home office!

I am looking forward to my upcoming trip to Turkey and Armenia -- who will I see there?

@QuinnyPig now you can afford a haircut.

So what've you folks been up to? I've been a bit distracted lately...

Claude Sonnet 4.6 is live in Kiro. It delivers reasoning closer to Opus and improves token efficiency over Sonnet 4.5. It can: • Build, refactor, and debug with context intact • Maintain long spec workflows • Handle tool calls and subagents Available in the IDE and CLI for Pro, Pro+, and Power users. Restart Kiro and put it to work. 👉 spr.ly/6017hjKiT #Kiro #Kirodotdev #AICoding
