All Things Cloud and Observability. Principal Systems Engineer at Cloudflare. Opinions my own.

Me and a band of plucky misfits (@maks_mak_0 and a few others), codename the Alertocats 🙀, have started rebuilding Cloudflare's whole notifications and alerting experience.

First up: a brand new UI. Find it in the dash at Observability → Alerts 👇

@JeremyMorrell I hear this small company Cloudflare has a decent thing for this, probably nothing

What started out as "I don't need GitHub because I'm building this solo" is slowly turning into building my build & deploy tooling, my own Claude Code remote harness... But in a "this is good actually" way

@Xjohannesh Claude Code cloud only integrates with GitHub

[Brendan Irvine-Broque @irvinebroque]

more new OTEL tracing APIs in the Workers runtime from @JeremyMorrell:

spanContext()
setStatus()
updateName()

say it with me now — OpenTelemetry with zero dependencies

Draw architecture on whiteboard. Take picture. Use AI to create SVG from it. Then create a spec from the SVG. Then implement.

Idk, that might be a really great workflow, actually. Gonna have to try it out.

in: https://t.co/CgQ10VDDY3 read this and make prod faster and more efficient

out: Stuck cohorts replay the same videos every tick without committing anything. That is 84% of backend CPU and about 5 million D1 statements a day on the primary. The fix is committed and tested.

we've been dogfooding this for a few weeks now and it's such an unlock for teams building on workers! no more mystery box

importantly — you can now find and profile a durable object!

[rita kozlov 🐀 @ritakozlov]

the beauty of building on our platform: we just used the new CPU profiler on the worker behind d1

improved CPU utilization by 30% and improved RPS throughput for customers 🤯

I joined a hockey pool this year (stats are fun!) and I realized two things. The "fantasy sports" platform are over featured for the "office pool" crowd and so many people don't ahve access to good data tools in this space.

So I'm setting out to build something better.

my lighting talk from cloudflare connect on building artifacts in 3 weeks is up!

@yusuktan @Cloudflare what? I never got a package!

[William Perron 🚀 @_wperron]

Is there such a thing as software that is *too* extensible or customizable?

[Corey Quinn @QuinnyPig]

The replies to this make it pretty freaking obvious just how much mindshare Cloudflare has.

And @awscloud in its infinite wisdom just made them the belle of the ball instead of “one out of hundreds of other vendors.”

[ClaudeDevs @ClaudeDevs]

Now in public beta, Claude Platform can send OpenTelemetry traces from the Messages API, Claude Managed Agents, and the Claude SDKs to your observability stack.

@zlwaterfield This chart is nonesense. How does Montreal have fewer "lifestyle perks" than Quebec? How is cost-of-living lower in Ottawa than Montreal?

[William Perron 🚀 @_wperron]

@yusuktan This is acceptable

[William Perron 🚀 @_wperron]

@yusuktan Something with flame decals

[William Perron 🚀 @_wperron]

@yusuktan Do it, but make sure it's a cool car
