@dhh That’s impressive! 👏
Recently, after yet another downtime of a vendor I built the this one for fun.
Keen to hear your thoughts on reliability challenges in the new “AI era”.

[Elad Leev @Eladleev]

Vendor went down again.
I thought - do they *actually* deliver on their advertised 99.9% uptime..?

So I built https://t.co/llZhXUicPK to find out. Scoring isn't perfect, and a bit naive (https://t.co/haKtXjsZCJ), but the gap between promised and actual uptime was eye-opening!

@gwenshap 2015, right after the “init wars”, had to switch all our fleet to systemd. Pushed a bad Puppet module which took down *all services including SSH* of entire region running on OpenStack. Was a 2 days nightmare to recover.

@ReadwiseReader @readwise Looks awesome! For me, the most used feature of Pocket was offline reading. Doing some tests with @ReadwiseReader, it seems like I need to click every article to sync it offline?

During the power outage in Spain and Portugal, the local AWS datacentres kept humming thanks to careful planning and preparation. Remember: Everything fails, all the time, so plan for failure and nothing fails.

I've spent the past ~2 years thinking about building on top of object storage, especially about trying to build high throughput low latency OLAP-like systems. So I wrote down some of my thoughts and lessons >>>

@gwenshap A mixture of Kafka Connect and Flink.
In our case, we wrapped it in our own CRDs to abstract away most of the burden involved. Devs just deploy a “Connector” object with minimal configuration and behind the scenes all the magic happens

A new Jepsen report, and as always, super interesting. 🔥

[Elad Leev @Eladleev]

@gunnarmorling 👋
As part of our Kafka clients, we ingest them as msg headers. For now, just useful for debugging, in the future the plan is to integrate it as part of Data governance, policies and discoverability
