> No one is ever going back and reading individual commits

I do, regularly! In a repository where care has been taken, it can be super valuable when tracking down a bug or regression, and understanding the intent of the author

New comment by jhealy in "ISO PDF spec is getting Brotli – ~20 % smaller documents with no quality loss"

jhealy — Thu, 22 Jan 2026 20:55:03 +0000

The article is wrong, the PDF spec has introduced breaking changes plenty of times. It’s done slowly and conservatively though, particularly now that the format is an ISO spec.

The PDF format is versioned, and in the past new versions have introduced things like new types of encryption. It’s quite probable that a v1.7 compliant PDF won’t open on a reader app written when v1.3 was the latest standard.

New comment by jhealy in "T-Ruby is Ruby with syntax for types"

jhealy — Sat, 27 Dec 2025 02:36:30 +0000

interesting idea, good on them for trying something different in the Ruby ecosystem.

The website is quite extensive, but the gem only has ~1.5k downloads. It’s presumably very early on the adoption curve

At a previous employer we did this with our docs repo.

The public docs site was managed and deployed via a private GitHub repository, and we had a public GitHub repo that mirrored it.

The link between them was an action on the private repo that pushed each new man commit to the mirror. Customer PRs on the public mirror would be merged into the private repo, auto synced to the mirror, and GH would mark the public PR as merged when it noticed the PR commits were all on main.

It was a bit of a headache, but worked well enough once stag involved in docs built up some workflow conventions. The driver for the setup was the docs writers want the option to develop pre-release docs discretely, but customer contributions were also valued.

Since 2024 you can disable the root credentials on all accounts except the Organization management account: https://aws.amazon.com/blogs/aws/centrally-managing-root-acc...

I don't think the post mortem details whether the root access was on the org management account or an org member account.

Not really a new vulnerability, and yet Notion just shipped it this week. All caution thrown to the wind in the name of an announce-able AI feature

I live in Melbourne (on Jemena’s distribution network) and this isn’t my experience.

Our power is very reliable and rarely goes out. Every few years a car hits a pole or something and we get a brief period of quiet time
