.git/info/exclude is one of my favorite git features, but I'm always surprised when I talk to people who never heard about it.
It basically allows you to add stuff to .gitignore without modifying the file. Great for ad-hoc ignoring some files created during debugging.
Terminal is SO back baby. Dusted off my dotfiles for the first time since college and I forgot how satisfying this rabbit hole is.
Nothing like spending 3 hours perfecting my shell workflow to avoid the actual work I was supposed to do.

Fixed an issue solo on my phone while the little one fell asleep. Claude + GitHub apps made it work. Future is weird 💤
Dependabot security alerts have terrible signal-to-noise ratio, especially for Go vulns. That hurts security!
Just turn it off and set up a pair of scheduled GitHub Actions, one running govulncheck and the other running CI with the latest version of your deps.
Less work, less risk, better results!

Go 1.26 has a lot to love, including significant performance improvements that are completely transparent to Go developers. Just upgrade and your Go programs run faster -- no other changes required!

very cool!
What if Claude Code is “a guy in the Philippines”? 🤔🧐🤨
Two speakers at FOSDEM on stage
Front row seats to @kakkoyun.me's talk #FOSDEM
I’m glad to have been able to catch my colleagues @kakkoyun.me and Augusto de Oliveira’s talk. I’m an internal user of our benchmarking platform at @datadoghq.com and I learnt a few more things! Nice talk! #FOSDEM #FOSDEM26 #FOSDEM2026
Woohoo! @kakkoyun.me hits twice at #FOSDEM with another talk. Now with Hannah Kim, talking about how to instrument your #Go code without changing a line. #FOSDEM26 #FOSDEM2026
That time of year has come! It’s FOSDEM o’clock.
Who looks to the code nowadays? /s
(I know that much vim to browse around)
So far this was for a really small experiment. I don't know if this approach scales 😅
Even for provisioning and fixing setup issues, I used Claude Code.
Turns out the missing piece wasn’t discipline or memorizing modal keybindings, but delegation (probably this is how manager feels /s).
Running Claude Code on a Linux box over SSH just unlocked a whole new world for me.
I’ve never managed to become an avid Vim user (too impatient, and lazy), but now I can code comfortably through SSH with Claude doing the heavy lifting.
Noop, apparently it didn’t make the cut.

Time to pick this up again. It’s getting more relevant everyday.
With #FlightRecorder #Go introduced a powerful tool. As I'm involved in the #OTel Profiles signal, I have created an OTel receiver that transforms Go's FlightRecorder format into the OTel Profiles signal. Now you can analyze Go diagnostics in your own favorite backend/UI!

Related #golang PSA:
Gophers often mistakenly put a -u in 'go get -u foo', when they would have been better off with just 'go get foo'.
'go get foo' says to upgrade foo itself. It's shorthand for 'go get foo@upgrade'
'go get -u foo' says to *also* upgrade all the direct and indirect deps of foo.

FIRE subreddits are wild. Everyone’s 29, retired, owns 3 rentals, and “just got lucky with some BS hype .” Meanwhile I’m emotionally attached to my budgeting app.
