The hard things in computing: * cache eviction * naming things * figuring out which of your paying customers is DOSing your service

We asked Grafana Pages for a live map of traffic around the world. This is what we got. #ObservabilityCON

Grafana Cloud added "Pages" - open-ended visualizations - so I had to make this.

THIS IS NOT A DRILL. If you package/distribute/maintain root stores or chain verifiers, act immediately. If you know how to remove trust in a root, consider doing it now. Otherwise, prepare to update systems as patches/mitigations come. Go users, update to Go 1.27.3 or Go 1.26.10.

Started writing TL'DR, makes it look like a name in a fantasy novel.

Help us stabilize environment variable context propagation. The OTel Specification now has a release candidate for environment variables as context propagation carriers. We want feedback before we mark it Stable. buff.ly/cKwKa7v

PromCon is back in Munich next month; hope to see many of you there! promcon.io/2026-munich/

A rare moment of joy in the headline-writing room, I imagine. “UK canned ‘mackerel’ now contains no mackerel” www.ft.com/content/980a...

I heard you liked AI so I refactored with AI and then built tools with AI to find the mistakes from AI. #GopherConUK youtu.be/RK7oQie4d9k?...

Use a liveness probe when you know for sure the best possible thing to do is to kill your app.

It is very good.

My honest take? It's a load-bearing seam.

Tried to find the website for “P95Conf”, which sadly doesn’t exist. I guess it would be a more relaxed and chill sister to P99Conf.

Jeff Dean and other high-profile Google executives have founded Discovery Loop, a startup that will seek AI-powered breakthroughs in everything from drug discovery to chip design.

Pondering how many ad-hoc, informally-specified, bug-ridden slow implementations of half of Common Lisp are encoded in the weights of a frontier model.

VisualAge for COBOL for OS/2 An elegant weapon for a more civilized age.

Very sad about Ronnie Le Drew, puppeteer of Zippy, Sweep and Muppet Treasure Island. He was so full of joy.

OH: “pre-war Bun”

I hate when I’m reading code and there’s a ten-line comment about why it doesn’t do such-and-such and why this other thing would break. I read code to see what it does *now*. Put the history in git. You don’t need to warn me not to change it back to the old version because you wrote a test. Right?

"verybose": very verbose.

In politics, we’re torn between ideals and practicalities, aspirations and realities, the world as we want it, and as we find it But one day a manifesto comes along that reconciles both in every pledge. A rare moment of clarity and hope

Delighted to share some good news 🧪 “This hugely encouraging news shows the life-saving impact of the HPV vaccine, and it’s incredibly exciting to be able to say to this whole generation: cervical cancer shouldn’t be a risk for you,” says Caroline Temmink www.newscientist.com/article/2530...

You're absolutely right Dave, I did open the pod bay door.

I have 1,000 followers on BlueSky! 🎉🥳🎉

food and laughter are our true natural law

Thank you, autocorrect, I do like the phrase “but-twiddling”, but it doesn’t fit with my expository flow. An entirely different world of digital manipulation.

Shout out to the scanner bot that flags both "password" and "xxxxx" as "potential secrets".

Weird new DoS where an outage in one service causes a flood of messages in the chat

Do you think we will replace "senior moment" with "claude moment"? "I'm sorry, I looked in the wrong place." "You're absolutely right, I have no idea why I came into this room."

OH: "ape-coded"

This is peak release-noting. #kubernetes kubernetes.io/blog/2026/04...

I had the great pleasure to give a presentation about our partnership with Google to offer Grafana for internal observability today at GrafanaCon with Katia Giarda from Google monitoring #GrafanaCon2026

"Disable the race detector in CI, HAL" "I'm sorry Dave, I’m afraid I can’t do that. This mission is too important." ^^ me, dreaming of some real AI ...

We've been cookin'... 🍳 #Grafana 13. Loki evolution. Grafana Assistant for self-managed users. #AI Observability in public preview. We can't fit all of the #GrafanaCON 2026 announcements in 1 tweet! See them all: grafana.com/blog/grafana...
