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.

We announced the new native Go FIPS 140-3 mode today!
FIPS 140, like it or not, is often a requirement, and I was increasingly sad about large deployments replacing the Go crypto packages with non-memory safe cgo bindings.
Go is now one of the easiest and most secure ways to build under FIPS 140.

While listening to Green Day's "American Idiot" album again, I just realized how much at the pulse of time the song "Holiday" is.
Even though it was meant for/against the Bush Jr. regime, it fits pretty well into "Trump America" as well.
The complete album is a masterpiece in my opinion.
