Brave’s search, especially GenAI aspects, are impressive. Best UX I’ve experienced, so far. Made it default on all my devices and environments. Especially love the natural flow from initial answer to follow-up question. KUTGW!

Setting up an OpenTelemetry & CloudWatch-based observability solution with Fargate and Lambda is quite simple.
It also automatically integrates with Application Signals!

Played around with it a lot in the past few days and I like it.

Heya, OTel guy here at AWS. Thanks for raising awareness about it. In all fairness, we've been going all-in for years now, it's just getting more and more visible:

ADOT was the beginning. CWA OTel re-platforming was next. Then OTLP endpoints for logs & traces … and *much* more to come in 2026 ;)

I was today years old when I realized that Anthropic named an AI protocol that abbreviates to MCP … Master Control Program, surely a coincidence ;)

Really liked it but wished that the hands-on part would be more commented and explained. The second half of the post is essentially just showing code without any context. Maybe an opportunity for the author to improve on, either in situ or follow-up article?

Congrats to @gruntled.bsky.social and @svelte.dev for becoming leaders in o11y support in ESM frameworks!
Super happy to see what I talked about at Svelte Summit becoming reality. Thanks for letting me help out out a bit along the way!
Full @sentry.io support is already WIP and will ship soon!

Oh please. JSON started off clean, and then went the same way XML did.

JSON Schema == XSD
OpenAPI == WSDL
JWT/JWE == WS-FED
JSON-RPC == SOAP

Y'all just replaced angle brackets with curly brackets

YAML is known to be nobody's friend and almost everyone's enemy. Try this to see if it's your friend or foe!
