Good morning! Just wanted to let you all know that Rian Johnson subtly rickrolled us with a scene in Wake Up Dead Man. [bsky.app]

Just watched the new Knives Out and I think it’s really important you know that the scene in the Seminary’s Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up. I saw the window tracery and immediately made my friends pause the film so I could tell them.

And to be clear: the action one does if one is feeling guilty tonight or tomorrow is give cash to organizations feeding the hungry and sheltering the houseless. It is not to show up at a shelter and ask to serve food.

You gotta get vetted to volunteer, so you start with cash, put a reminder —
Pope Leo said in a Christmas Eve sermon that the story of Jesus being born in a stable because there was no room at an inn should remind Christians that refusing to help the poor and strangers today is tantamount to rejecting God himself. For @reuters.com

Just saw "Swiftian" used in a puzzling way in a sentence, and it suddenly made sense when I realized the writer meant "like Taylor", not "like Jonathan".

In case you missed it Canada changed their citizenship laws recently.

If you have Canadian ancestry you may be eligible for citizenship by descent.

I need to look into it some more but this is amazing.

Someone asked what's happening here - the watered tree is lit on fire a full 30 seconds before the dry tree, but you can barely tell because it's burning so slowly. The dry tree goes full inferno in a matter of seconds. Water your tree. Make sure you have working smoke alarms in your home.

You might be thinking, "CPSC, does a dry Christmas tree really burn that much faster than a well-watered tree?"

Friend, let's find out together by watching this PSA.

If you have never worked inside a big high-functioning human knowledge organization, this is a good rundown of what that feels like
we are strictly zero tolerance absolutely forbidden to use genAI at work. we have large caseload and a specialized area. Know what we do other than use resources on the intranet? We are constantly on teams asking the brain trust of our department.

what scares me the most is that knowing things is not very helpful if you can't combine the different things you know to make new things. I stock up on knowledge like I'm filling a pantry and I can make so many new ideas out of them!

I don't want a brain full of only inflexible frozen dinners!
The point is not to put more fact shaped things in your head than anyone else. It’s to understand the ones that are there on a deep and meaningful level.

When we say "no, everything hasn't been digitized," I need you to understand that we really mean is that virtually nothing has been digitized. This is because the realm of primary sources that historians use is incomprehensibly large.

The work that scholars and researchers actually do is the work that people *think* AI is doing. You read all sorts of things. You make connections. You notice where the holes are — what *hasn’t* been observed, questioned, investigated. You synthesize it into something that has never existed before.

I tend to think we've invisibilized work that involves sensemaking in the interests of pushing solutions. Thinking of @debcha.bsky.social's 2015 essay "Why I am not a maker"

Why decline all these chances to defend feminism? Because to participate would be accepting the premise that our rights and humanity are up for debate in the first place.

Once you’ve conceded that it’s reasonable to ask whether women’s equality was a mistake, you’ve already lost.

This essay by the author of a recent well-reviewed book about Tolkien starts modestly and then stabs you with a Morgul-blade halfway through, where you are pinioned by a twist in the telling. You may never recover. www.nytimes.com/2025/12/19/o...

(not) sorry to keep hammering the point, but this really is the thing: as AI-generated video becomes more sophisticated, it will only become harder for non-experts to tell what's real and what isn't based on incongruous details, but an old-fashioned "source??" will always give the sloppers away.

I regularly get asked if I’m hopeful. Or optimistic.

My answer is always the same.

What I am, is determined.

I can’t believe it’s going to be 2026 soon. What an absurd number. Where are the spaceships. Where did the last ten years go. How am I living here in the future that is also somehow the distant past?

my favorite thing about the benoit blanc movies is that they aren't really about benoit blanc. he is not grappling with demons from his past. we are not getting flashbacks to the husband whose murder he never solved. he just shows up and does his job like mary poppins for homicides

the line is actually "no JESUS for us meeses," an oblique reference to the fact that, as muppets are unable to take communion, they are forbidden from entering the kingdom of god
