Honestly stick with it. Took me about two weeks, but I finally stopped recoiling and started preferring it.

I would trust x.com/VanL / www.linkedin.com/in/vanlindberg, at least for a referral. He literally wrote the (O'Reilly) book on Intellectual Property and Open Source.

Children of Men is great, but my favorite bit is the showreel from the design firm hired to do all of the signage, advertisements, etc. that quietly sit in the background and keep the world grounded vimeo.com/37658689

As someone who grew up in Georgia, Texas, and Minnesota, the existence of United Airlines feels like a polite fiction. I mean, I totally get it. I wish there was a third legacy carrier, too. But we've got to play the hand we're dealt.

I don't even know what else is foundational in my toolkit and ripe for disruption. Python? Markdown? HTML? HTTP? Tools like ripgrep, ghostty, etc. don't feel like they're in scope since they're not so enmeshed with how things get done.

Just like last year, we replaced a whole wall of movie posters with our own punny movie posters at the cinema where RustWeek 2026 took place. I designed seven new posters for this year's event. See the thread below 👇

Nine movie posters displayed next to each other.

I could've done this with git! But `jj undo` made it much safer, and deferred conflict resolution made it much easier. The workflow as a whole was just dramatically smoother when juggling commits.

We had an internal fork and someone accidentally squash-merged a branch with ~1500 commits into it. Mostly upstream changes, but some of our own too. Only noticed months later when adopting a new upstream release. With jj, I was able to pick apart the merge and rebase everything within a day.

Finally had a chance to use #jj-vcs to address a complex problem, and I'm never going back to plain git. Absolutely unreal how easy it made things. It is indeed simpler, safer, and yet more powerful than Git alone.

Red Hat OpenShift uses CRI-O to pull container images. CRI-O sends one `Accept` header per supported MIME type. Harbor only serves OCI artifacts if a client sends OCI Accept headers. CloudFront drops repeated Accept headers. ∴ Putting CloudFront between OpenShift and Harbor breaks image pulls.

Dan Callahan @callahad.com · 20/04/2026

If you send multiple `Accept` headers, CloudFront drops all but the first. RFC 9110 § 5.2 and 5.3 gives specific examples of when repeated headers are acceptable, and how to handle them. The Accept header fits this definition. Amazon says it doesn't. Sigh. www.rfc-editor.org/rfc/rfc9110....

Dealing with a customer issue that, as far as I can tell, is ultimately caused by AWS CloudFront implementing HTTP incorrectly. Amazon support keeps quoting an RFC section at me, but that section agrees with my interpretation? (And my understanding is shared by RedHat and NGINX...) 🤦‍♂️

I also enjoy letterpress printmaking and lead type. No practical value, but an enjoyable craft. I'm fine if software goes the same route. Let it be digital bonsai. The economic and societal ramifications are what scare me. The craft will still be there for those who want it.

Yeah that's looks reasonably beefy :) On my Christmas list was a stick of 32 GB DDR5 with "only buy if under £x" because it had been fluctuating a teeny bit over the summer. 💀 TrueNAS is Debian-based these days, but I'm trying to avoid using the NAS as anything other than an appliance...

Dan Callahan @callahad.com · 30/12/2025

What sort of build did you do? I just set up a Terramaster F4-425 Plus with TrueNAS, coming from an old Synology DS-216+II and ... I'm not yet totally happy? Still really tempted to just blow it away and install NixOS.

How did that compare to your expectations for each platform? (I'd wager that both seem low?) I've noticed that my own desire to engage on social media flatlined a few years ago, doubly so on public platforms. It still feels like something is missing, but I haven't been able to fill that void.

For more "generally interesting" stuff, @reckless.bsky.social is a stupendously skilled interviewer, and his Decoder podcast is a solid choice: www.theverge.com/decoder-podc... For consumer tech, The Vergecast is good (but publishes quite frequently): www.theverge.com/the-vergecast

The second two books will do the same to you! Quite distinct from the first two, but also good.

It's not epic fantasy, but I'll always recommend Annihilation by Jeff VanderMeer as a good / weird / disquieting read. Or for classic sci-fi/fantasy, I recently really enjoyed Dan Simmons's Hyperion Cantos.

The self-encrypting drive is fun. On my previous laptop I was happy enough to manually unlock it in a PBA image. But if I can use the TPM to do it for me... (The previous laptop also needed a patched sedutil to support resuming from s3 sleep, but now everything is s0ix, so at least that's over?)

Dan Callahan @callahad.com · 16/12/2024

The last two months were bisecting the kernel due to a regression in MediaTek firmware that caused failures resuming from hibernation. Had to stop my months-long bcachefs experiment to do the bisecting, because it changed its on-disk format across the same range of kernel commits as the regression.

Who needs arts, entertainment, or hobbies when you have #NixOS? I've had my Framework 16 for 10 months. I still haven't "finished" installing Linux on it. This month's time sink: Using LUKS2 to configure a TCG Opal Self-Encrypting Drive and have it auto-unlock via TPM2 (protected by SecureBoot.)
