I have lots of Thoughts about technology marketing (that led to a lot of the way Rust did things, and was borne out of… previous experiences) but the biggest one is: you gotta define yourself on your own terms rather than in opposition to something else

If you read ✨one post✨ this year about instrumentation, OTel, logs, tracing, or observability 2.0, make it this one. It's just that fucking good.
It has code samples. It is also a great overview of your options in the o11y 2.0 space, incl vendors, OSS and hybrid.

I'm curious how other people are designing systems that do a lot of scheduling/monitoring work.
What I landed on might be considered heavy handed?
But I'm pretty happy with its development, testing, cost, and HA properties/tradeoffs.

I'm tired of explaining the difference in classified mishandling between Trump, Biden, Pence, and Clinton. So, I wrote it all down in this post, complete with footnotes. Now I hope to never speak on this again. https://infosec.exchange/@jschuh/110551298514321829

Thinking about high call-rate services with purely serverless APIs, and tried to be realistic about the cost model.
In my experience, there's a constant hum of throttles and authentication errors, and we should try to predict and model those if we can. Better: first class support from vendors.

My most recent post is about one approach to "up front" work I encountered when using DynamoDB (beyond the typical denormalization).
