It's amazing how high a number you can get to with a deck of cards!
Apr. 20th, 2026 03:57 pmTo imagine the number of ways a standard pack of playing cards can be uniquely shuffled, follow these simple instructions:
Go to the equator with a deck of cards and start shuffling them. Shuffle them so that every second you produce a new and unique ordering of cards. Keep shuffling them over and over, a new ordering, every second, for a billion years.
At the end of a billion years take a single step forward.
Keep shuffling.
Every billion years keep taking a single step forward.
Once you have circumnavigated the Earth, take a single drop of water out of the Pacific Ocean. Keep shuffling. Keep taking a single step every billion years. Keep taking a single drop of water out of the Pacific Ocean each time you walk around the Earth.
Once the Pacific Ocean is dry, refill it and place a single piece of paper on the ground.
Keep shuffling.
Keep taking billion year steps. Keep taking a drop out of the Pacific Ocean with each return to your start point. Keep refilling the Pacific Ocean once dry. Keep building your tower of paper one sheet at a time.
Once your tower of paper is as tall as Mount Everest, throw it away and place a single grain of sand on a weighing scale.
Don't stop shuffling.
Don't stop taking a step every billion years.
Don't stop emptying the Pacific Ocean and refilling it to build an Everest of paper.
Don't stop throwing your paper tower away to place another grain of sand on your weighing scales.
On the other side of your scale is a bull elephant. When it raises off the ground you will be half way done.

Frieren: Beyond Journey's End: A review
Apr. 19th, 2026 03:39 pmIt is, in background, a bunch of totally standard fantasy tropes. But it does something interesting with them, which is to base itself after the point most stories end. This is the story of what happens to Frieren, an immortal* elven mage, after her adventuring party defeat The Demon King. And how she lives in a world where the friends she makes live much shorter lives than her, how she connects with the people around her, and what she does when she realises that this matters to her.
There is plot, and action**, but mostly not that much of it. The point is the people, and watching them orbit each other, learn from each other, or completely fail to. The characters are interesting, and I love feeling that there is much more to most of them than is obvious on the surface. I particularly loved the first few episodes, which set everything up, but even once we get past past these in to the ongoing arc*** I have found myself looking forward to the next episode more than in almost any TV I've seen in the last decade.
I suspect some people will get put off by some of the tropes, both the ones taken straight from fantasy/roleplaying and the ones that are stock anime conventions. But I could happily look past those and enjoy the meat of the show, which was excellent. I eagerly await season 2. The only nervousness I have is that the original manga has been on hiatus since October, and the creators have clearly struggled with the production schedule, so I don't know whether it will ever be completed. But, frankly, it's not (at this point) the kind of show where I need an ending, I'm delighted just to be along for the ride.
* It is not clear how long elves live. But it is clearly at least thousands of years.
** And when it happens it is gorgeously animated
*** I'm not sure it's a plot, as such. Things are happening, but I'm not convinced that it's going somewhere in particular more than it is just following characters around to see what they get up to.

The case of the missing notifications
Apr. 11th, 2026 11:58 pmI keep forgetting to post about this: we've been troubleshooting the "missing notifications" problem for the past few days. (Well, I say "we", really I mean Mark and Robby; I'm just the amanuensis.) It's been one of those annoying loops of "find a logical explanation for what could be causing the problem, fix that thing, observe that the problem gets better for some people but doesn't go away completely, go back to step one and start again", sigh.
Mark is hauling out the heavy debugging ordinance to try to find the root cause. Once he's done building all the extra logging tools he needs, he'll comment to this entry. After he does, if you find a comment that should have gone to your inbox and sent an email notification but didn't, leave him a link to the comment that should have sent the notification, as long as the comment itself was made after Mark says he's collecting them. (I'd wait and post this after he gets the debug code in but I need to go to sleep and he's not sure how long it will take!)
We're sorry about the hassle! Irregular/sporadic issues like this are really hard to troubleshoot because it's impossible to know if they're fixed or if they're just not happening while you're looking. With luck, this will give us enough information to figure out the root cause for real this time.
