GopherCon UK is an annual event with two multi-track conference days and one workshop day, held in the Brewery, in the heart of London.

Speaking at www.gophercon.co.uk this year!

If you’re thinking of coming but cost is a blocker, I’ve got some promo codes I can share.

Just DM me – happy to help!

β€œReason 5: OTel SDKs are complex and can be very slow”

It is really challenging to maintain this level of performance and simplicity without breaking any of the downstream systems like Kubernetes and Prometheus.

How we tracked down a Go 1.24 memory regression across hundreds of pods | Datadog We rolled out Go 1.24 and saw a memory regression. Here's how we dug into system metrics, uncovered a bug in the runtime allocator, and worked with the Go team to help fix it.

Fantastic new blog post from my colleague Nayef.

If you're into Go internals, check it out!

πŸ‘‡ This is what we have been working on.

It is a must-watch if you would rather not instrument your #go programs yet want to have all the benefits of observability!

And Hannah is awesome! Brace yourself for the first-class memes!

AI is a tool (sorry!) that people who are bad at their jobs will use badly and that people who are good at their jobs will maybe, possibly find some uses for. People who are terrible at their jobs (many executives), will tell their employees that they β€œneed” to use AI, that their jobs depend on it, that they must become more productive, and that becoming an AI-first company is the strategy that will save them from the old failed strategy, which itself was the new strategy after other failed business models.

The only journalism business strategy that works, and that will ever work in a sustainable way, is if you create something of value that people (human beings, not bots) want to read or watch or listen to, and that they cannot find anywhere else.

errors.isΒ -Β errors Resources and Information. errors.is is your first and best source for all of the information you’re looking for. From general topics to more of what you would expect to find here, errors.is has it all. We hope you find what…

Looking for a tool that automatically rewrites old error-checking patterns to use errors.Is / errors.As for #golang

I know github.com/polyfloyd/go... catches these issues, but I need something that fixes them. Does such a tool exist?
