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

O11y Masters: Observability Engineering Masterclass with Liz Fong-Jones

A six-session live masterclass with Liz Fong-Jones, turning Observability Engineering into practice. Aug 3 – Oct 14, 2026.

go.hny.co

Monday 10am Pacific / 1pm Eastern: the first session of my Observability Engineering Masterclass series goes live. 45 minutes, live demos & code. Recording plus a self-serve lab go out right after, so you can work through it again at your own pace or share with your team. New class every 2 weeks.

For @cocore.dev in the last day I - converted ALL of the backend code to idiomatic effect - added o11y and @honeycomb.io - squashed the top errors that were obvious Pre ai all that is a weeks long effort, some I’d even have to learn a lot (effect) Now it’s super high quality, no effort.

I find it hilarious that engineers will spend days, weeks even, curating their token dashboard for their claude code session, when they'll spend practically zero time adding telemetry to their apps to make it better. Claude Code: heres 72 graphs and dashboards. Production: install agent, go home.

@scott.hanselman.com do you think you'll be doing a hands-on review of the Surface Laptop Ultra? I'm really interested in the local coding potential, especially when coupled with Copilot and model switching for different tasks.

This is why humans with experience in scaling, architectural design, and ultimately "running stuff in production" will not be replaced by AI. My approach is both simpler, and faster, therefore saving money and making it more efficient too.

Is it an Agent, or 70 LLM calls in a trenchcoat?

Typescript people couldn't possibly like C# because it's made by Microsoft and Typescript is made by.... *checks notes*... oh dear. Well, at least Typescript is Open Source and .NET is... *checks notes*... oh dear. Maybe you're right Lou.

If you love TypeScript, you’ll probably enjoy C#. If you love C#, you’ll probably enjoy TypeScript. Hard pill to swallow for some, but it’s true.

@scott.hanselman.com what should I order from Chipotle? Figured I should try one while I'm over in the US.

I'm currently working in the office of a company I work at, like it's 2019 or something. It's weird. 8 years after doing my first talk about Honeycomb, I'm finally in the office!

People who place their "under seat" bag in the overhead bin on flights should be asked to leave the plane and denied boarding for 6 months after. Signed... someone who's been delayed by 20 mins because of inconsiderate assholes.

Engineering Your .NET Telemetry with OpenTelemetry Weaver, Tue, May 12, 2026, 6:00 PM | Meetup

Most telemetry is held together with string literals and good intentions. This talk shows how OpenTelemetry Weaver lets you treat your .NET application's telemetry like a p

I only learned today that Docker Desktop on Windows doesn't allow containers to access resources on your local LAN. This feels like a major limitation but I can't find a tonne of documentation about it. As I'm moving more and more of my stuff locally, this is becoming a problem.

Looking forward to presenting at this year's #o11ycon. I'll be presenting "Scale Brilliance, Not Bottlenecks: Building Platforms for the AI-First World" and sharing some of the most recent findings from @dora.dev. See you there! @honeycomb.bsky.social Register now: go.hny.co/477EmlY

Also happy to arrange this for people who can't afford it. Its in person, so you'll either need to be SF based, or going to be there for the dates.

psst, want an exclusive discount code for events.honeycomb.io/o11yConSF2026? DM me, I definitely don't want cost to be a barrier to anyone who is in my network who wants to come :)

Hey, all! Super early-bird pricing for #KCDC, Sept 9-11, ends tomorrow. I'll be there speaking about Open Telemetry and the importance of great logging in your apps.

KCDC 2026

The Kansas City Developer Conference is excited to announce our 17th annual event! Our 2026 conference will be held September 9-11, 2026, with a pre-conference workshop day and two full conference days. Once again, the event will be held at the Kansas City Convention Center in downtown Kansas City. Each year, we draw a large audience of new and experienced Developers, Architects, UI/UX Designers, QA Professionals, PMs, and Technology Managers from the Kansas City region, across the United States, and around the world. We hope you will join us!

This is the conference I've been organising for the last few months, we managed to secure speakers from Stackoverflow Salesforce Slack Google Akamai MongoDB Stripe Github Superhuman Thoughtworks AWS Cribl RWX ... and we're still booking people. Early bird is only $100 too!

AI is accelerating software delivery—but does that create advantage or chaos? The teams winning aren’t just shipping faster. They’re learning faster. Observability is how. That’s what the Leadership Track at #O11yCon is all about. May 20–21, San Francisco 👉 buff.ly/wwblC7E

Shifting Left isn't always the right answer, and with metrics its better to shift as far right as possible This is post I created about using the OpenTelemetry Collector to generate RED Metrics in a cost effective way. There's also a prompt for Claude to do it :) www.honeycomb.io/blog/shiftin...

Shifting Metrics Right

In the shift left era where it feels like we’re pushing everything as far to the start of the SDLC as we can, it may seem counterintuitive to shift anything right. That is, however, exactly what ...

I get that disruptive passengers shouldn't be allowed to board the plane, but once they've caused a 40m delay for the rest of us, maybe just let them on and we'll deal with them?

Want a sneak peek at what’s coming to #O11yDayNYC? 👀 Martin Thwaites and Jamie Danielson are previewing the live demos they’ll be running, showcasing some of the new things Honeycomb has been building. See it all in action in NYC. 👉 buff.ly/FQn2yBn

I find it really interesting that buying a game to play with friends that I'll play for an hour or 2 for £15 is a tough decision, but heading out for beers and spending more than that on a taxi is not a decision at all?

AI is reshaping platform engineering, helping or hurting? Join Charity Majors, Lesley Cordero (The NYT), and others at O11yDay NYC 2026 for “Is AI Killing Platform Engineering or Saving It?” and get a preview of the new Observability Engineering book! 👉 buff.ly/fnIwrcZ

Does anyone know if it's possible to have a lambda execute in a Cognito identity context when the originator is an SQS/EventBridge async execution from a Lambda invoked in API Gateway APIGW => Lambda (cognito) => SQS => Lambda (cognito) @theburningmonk.com maybe?

I've spent the last few months building this event, from working with @aparker.io on the keynote about how Knowledge is the new Data to pulling in some amazing industry speakers. The best thing though, is that I got sign-off to show a sneak peak of the future of honeycomb. Not to be missed! #o11y

When working with an Agent that writes the code for you, would it be better to having the author in git be the agent and the "signed-off-by" be the user? That seems more accurate to whats going on. If you yolo it into git and push, there shouldn't be a signed off, showing that noone approved it
