Log everything, structure nothing, then can't find what you didn't know to look for. That's the trap last week's Observability Masterclass focused on. @lizthegrey.com built wide events live with OpenTelemetry. On demand now. Next up Aug 19: feedback loops x observability. 🐝 go.hny.co/4wdFfDj

hi Irish and UK SRE friends, @honeycomb.io is hiring an SRE in the UK or Ireland! You'll get to work with (IMHO) one of the best SRE teams in the industry, and help level up the rest of industry on o11y and SRE! job-boards.greenhouse.io/honeycomb/jo... job-boards.greenhouse.io/honeycomb/jo...

Does anyone I know work in infosec at IAG or British Airways? I have somehow gained access to someone else's PNR because my email address contact info was put on their reservation, shortly after I updated the email address on my own PNR. I suspect some kind of caching input replay issue.

I'm currently available for consulting work. If you need help with open source strategy, developer relations programs, Kubernetes & cloud native advisory, event programs, or technical content, including podcasts & live streams — let me know! Learn more at shortconsulting.io

Machine Learning Platform Engineering from @manning.com is an incredibly detailed look into all aspects of ML platforms and the their tools: MLflow, Kubeflow, and BentoML. The authors share insights on data analysis, model training, inference and serving, and monitoring. shortener.manning.com/wxr5

This article shows how to measure RAG behavior, not just generate answers: faithfulness, relevance, grounding, hallucination detection. Built with #Quarkus, #LangChain4j, and local LLMs. Written for #Java devs who ship to production. buff.ly/cLZpGIG #RAG #AIEngineering #LLM

Really enjoyed reading Practical FinOps by Mohamed (lnkd.in/gP4WdrCv) from @manning.com Discusses the FinOps framework and FOCUS in detail. Plenty of practical queries for AWS cost and data tracking! lnkd.in/g4P-aVr5

Yeah, thanks mate. Data quality is huge. Quality >> volume. 💯 But #Observability is so broken. Megavendors know it is the old CA "cash cow in the basement" (side note, Bjarne was actually a good guy and this was not his own isolated opinion). While in secret they all know it doesn't fucking work.

Migrating from #Fluentd to the OpenTelemetry Collector? Fluentd buffers to disk. The Collector defaults to memory - so a pod restart can mean lost #logging data. Here’s how to configure #OpenTelemetry persistent queues safely. 👉 dash0.link/otel-fluent-...

Hey. I don't know who needs to hear this. It's gonna be okay. We will get through this. This is, sadly, cyclical in human society. And we've always been okay. Eventually. It's okay to be afraid. To take a break to recharge. You can't pour from an empty cup. Please care for yourself. Hold on.

The #RootsTech schedule is live. I’ve just created my own schedule of talks I want to watch. I will be attending online #NotAtRootsRech

I made a substack: charitydotwtf.substack.com. Some people questioned the ethics of doing so, so I put the project on hold for a few days to think and ask questions. I have decided to stay. Here is why. (also xpost: charity.wtf/2025/12/19/h...) charitydotwtf.substack.com/p/hello-worl...

You will hear of launches and rumors of launches—but here's how to test Gemini 3 yourself. Pick one stubborn document or photo. Run it through our #genealogy research-tuned Gem today (Gemini 2.5). Save everything. When G3 lands, rerun the exact same prompts. If it's real, you'll feel the difference.
