Sadly, neither ChatGPT nor Claude can handle converting a list of 12 hex colors to RGB properly. They do it but mess up the order, so I still have to check everything by hand. Meh.

> As of the time of writing, disk prices per TB are around $12 for new disks, $8 for used disks, and $4 for tape. If we’re conservative and look only at new disks, that means that storing a petabyte costs about $12,000.

The FIPS 140-3 Go Cryptographic Module Go now has a built-in, native FIPS 140-3 compliant mode.

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.

TrunkVer TrunkVer is a SemVer-compatible versioning scheme for continuously-delivered, trunk-based applications and systems that don't follow a release scheme.

TrunkVer (trunkver.org) is the just extra steps for v0.0.<counter>-<whatever>

However, idea of including CI job looks interesting. The only question: how it will help when CI job log will disappear? :(

Try to guess why this command returns empty string:

```
systemctl list-units --type=service --all --no-pager | grep '^pref.*'
```

Yes, you're totally right: because every line starts with 2 spaces which breaks ^ in regexp.

argh.

Finally I bought USB-C do DisplayPort 1.4 (made by UGREEN) and guess who have 4K @ 160Hz.

BTW, somehow MBP M1 Pro handles only 144Hz but M3 Pro does 160Hz.

@jedisct1 on twitter: First practical SHA-256 collision for 32 steps. #fse2024

I made a throwaway twitter account just so I could read the replies to this, and it was a depressing experience.

The tweet (and OP) is legit, but it's an academic result - full sha256 has 64 rounds.

But everyone is losing their minds in the replies/quotes, thinking it's a full break...
