Was trying to go over the latest discussion and then saw this. Yeah, no... I'm good for now.

I've spent the past couple months hand crafting a new B-tree map implementation for Go. It's fast. Faster than Rust's BTreeMap. Faster than the fastest C++ (frozenca/btree). And about 2x faster than my current Go btree (tidwall/btree).

What did you expect? Between iOS 18 and 26 are basically 8 versions, no company keep releasing updates for an 8 versions old OS. Oh wait...

There is a 100% chance that at least one of those mails will say: "I need all of it, what's the ETA?"

I would never have expected that something as "simple" (to the uneducated eye) as printing and parsing floating points could be so complex. Very interesting read- even though I only understand 15-20% of it. Especially love to see this: "I expect some form of this Go code to ship in Go 1.27"

“Floating-Point Printing and Parsing Can Be Simple And Fast”

The fastest known floating-point printer and parsing algorithms - fixed-width printing, shortest-width printing, and parsing, all in 400 lines of Go.

Go proposal: Type-safe error checking errors.AsType is a modern alternative to errors.As.

Accepted! Go 1.26 will introduce errors.AsType — a modern, type-safe alternative to the clunky errors.As.

No reflection. No runtime panics. Concise code. This is big!

Pretty neat addition. Looking forward to use it.

waybar-weather v0.2.4 is out. Some exciting new features were added: GPSd for geolocation lookup, an alternate text template to show current or forecasted weather by clicking the widget and i18n support for all displayable elements.

Check it out! github.com/wneessen/way...

It's especially ironic, given that Go was CF's main language some years ago.

Cloudflare outage on November 18, 2025 Cloudflare suffered a service outage on November 18, 2025. The outage was triggered by a bug in generation logic for a Bot Management feature file causing many Cloudflare services to be affected.

So tempted to write a troll thread on how this incident shows Rust has bad error handling and wouldn’t have happened in Go, where we actually handle errors 🫣🫢😜

waybar-weather v0.2.0 is out and removes the depencency on Geoclue by implenting its own geolocation sub/pub bus. It also is now fully customizable via templates, allowing the user to make it look like they want.

Feedback is, as always, welcome!

Serious take: the solution to Safe Browsing false positives like the Immich one is passkeys.

Phishing regularly upends people's lives. The Safe Browsing cat-and-mouse with all its opaque false positives will be necessary until we roll out phishing-resistant auth.

It's been 14 months since the ML-KEM spec was published.

age still isn't PQ because it's waiting for trivial details of the HPKE hybrids to stabilize, but they are blocked on the CFRG.

The TLS, SSHM, and LAMPS (X.509) IETF WGs are not waiting for CFRG. I just posted a plea for HPKE to do the same.
