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 👇

more new OTEL tracing APIs in the Workers runtime from @JeremyMorrell:
spanContext()
setStatus()
updateName()
say it with me now — OpenTelemetry with zero dependencies

One week later, Pele is already in dozens of apps including @obsdmd 1.15 and @bot! Many improvements this week:
- Even faster rendering!
- Math resolver support: KaTeX, MathJax, Temml, etc
- Gradients in sankey diagrams
- Fewer edge crossings in diagrams with subgraphs
- Subscript, superscript and inline code in labels + text styles: kbd, underline, ins, cite and others
On a personal note, I am so grateful for all the love Pele received! I truly did not expect it.
My hope with Pele was to get a few bug reports ahead of the Obsidian release, so it's a wonderful feeling to see it adopted so quickly. I take this as a great honor and responsibility.
If you added Pele to your app or website, feel free to share it below 🌋
The amount of design thought that went into the humble update dialog by @almonk at @superlogical is insane. Truly unhinged levels of obsession.
Sparks joy every single time.

Same offer from @Cloudflare. 100 free passes to Cloudflare Connect in SF this week for folks with cancelled GHC registrations.
Email [email protected]. First come first serve.
We still want to find a way to bring the community together. If you planned to be in California for the Grace Hopper Celebration, I invite you to join us this year for GitHub Universe, Oct 28-29. 🌉
We've set aside 75 complimentary passes for folks with cancelled registrations. While this doesn't replace the conference and Universe has far fewer attendees than GHC, my hope is that it does give folks an opportunity to connect with each other. 📷 DM the GitHub team on LinkedIn or email me at [email protected] (first come first serve).
This is Pele, my new rendering library for diagrams and charts, compatible with the latest Mermaid syntax.
- 100-500× faster than mermaid.js
- 6× smaller bundle
- No dependencies
- Easy to theme
- Responsive to device width
In pursuit of making Obsidian insanely fast and cohesively designed, I always found the Mermaid library to be too big, too slow, and too hard to theme. Pele will be the new renderer in the next version of Obsidian, but you can start using it now.
Pele [ˈpɛlɛ] is named after the goddess of volcanoes and fire. It's open source under the MIT license. Try the playground!

Amazing blogpost from the Data Team here at @Cloudflare on how we optimized our ClickHouse platform and gained 2.5 YEARS of hardware runway.
If you've tried to by hardware this year, you know that's a huge win!
And as always, we're hiring :)

This isn't your typical acquisition blog post. I'm really excited not just that @rough__sea, @piscisaureus, and friends are joining, but also what they plan to work on: Making workerd a first-class, self-hostable open source runtime. Read for more:

Cloudflare Tracing is now in open beta 🚀
Our teams rely on traces everyday to understand what happens to a request as it moves through our platform. Cloudflare Traces brings that same visibility to you.
✅Get automatic spans throughout the entire request
✅Control what gets traced with trace rules
✅Propagate traces across your stack a la W3C trace context
✅Query traces through our dashboard, SQL API or Cloudflare MCP
✅Export traces to any OTLP-compatible destination
Introducing Cloudflare Traces
Today we're launching Cloudflare Traces, a way for you to get an unprecedented view into requests going through Cloudflare!
Why was a request blocked?
Why did a request fail?
Why was a request slow?
Find out with Traces!
