elaborate on the home automation pls

lcamtuf is doing that for decades!

Could you elaborate for those with less financial markets experience? Why trading spot is a waste of time?

I love his series. Eye opener for beginner coders.

Agree. From 6+ years of experience it seems that we got fouled by the multi-az promise of being able to survive datacenter outage.

You can survive datacenter (AZ) outage IF you have separate stacks per AZ and don't mix traffic. If you have Kafka cluster spread out in 3 AZ don't get surprised if you just LOWERED your availability because any issue in one AZ makes your stack unstable. And issues in single AZ are quite common.

VictoriaMetrics eats other TSDBs for breakfast.

PromQL support (with extensions) and clustered / HA mode. Great storage efficiency. Plays well for monitoring multiple k8s clusters, works great with Grafana, pretty easily deployed on k8s.

No affiliation, just a happy user.

Congrats to Grafana Team!

If you're looking at scaling your Prometheus setup - check out also Victoria Metrics.

Operational simplicity and scalability/robustness are what drive me to it.

I used to to send metrics from multiple Kubernetes clusters with Prometheus - each cluster having Prom with remote_write directive to send metrics to central VictoriaMetrics service.

That way my "edge" prometheus installations are practically "stateless", easily set up using prometheus-operator. You don't even need to add persistent storage to them.

AWS S3, as far as I know

More like cmd+l (address bar), n (autocompletes to news.ycombinator.com), enter.

At least I'm getting efficient at bad habits ;-)

At the time of making this presentation AWS did not have anything in their offer that could match tuned MySQL on i2 instances. Aurora was just getting started.

But nowadays? I'm all in for Aurora.

From experience: after company grew to more than .. 200-300 people and user management/termination became a big burden we hired a person that would write tools to automate user management, and if something wasn't supporting SAML we did manage users via its API. If API was not available then we reverted to "Termination checklist" aka manual work.

Clarification: it wasn't that persons only responsibility, just one of many assignments to help automate Ops in the company.
