Привет and welcome to our new Russian friends from LiveJournal! We are happy to offer you a new home. We will not require identification for you to post or comment. We also do not cooperate with Russian government requests for any information about your account unless they go through a United States court first. (And it hasn't happened in 16 years!)

Importing your journal from ЖЖ may be slow. There are a lot of you, with many posts and comments, and we have to limit how fast we download your information from ЖЖ so they don't block us. Please be patient! We have been watching and fixing errors, and we will go back to doing that after the holiday is over.

I am very sorry that we can't translate the site into Russian or offer support in Russian. We are a much, much smaller company than LiveJournal is, and my high school Russian classes were a very long time ago :) But at least we aren't owned by Sberbank!

С Новым Годом, and welcome home!

doubly dual shuffles

Here's a pearlescent xmas gift for you!

There are four variants of the algorithm for shuffling an array, arising from two independent choices:

  • whether to swap elements in the higher or lower parts of the array
  • whether the boundary between the parts moves upwards or downwards

The variants are perfectly symmetrical, but they work in two fundamentally different ways: sampling or permutation.

The most common variant is Richard Durstenfeld's shuffle algorithm, which moves the boundary downwards and swaps elements in the lower part of the array. Knuth describes it in TAOCP vol. 2 sect. 3.4.2; TAOCP doesn't discuss the other variants.

(Obeying Stigler's law, it is often called a "Fisher-Yates" shuffle, but their pre-computer algorithm is arguably different from the modern algorithm.)

At push of button, this year's Madness collection has 227 works in 183+ fandoms.

Madness collection

Main collection



AO3 wranglers have processed a lot of new fandoms; in the main collection, the 992 that appeared on the fandoms page at reveals have become 1065! Thanks to everyone who has helped make wranglers' jobs easier by using canonical tags, tags from the tag set, or other recommended tags, as appropriate in each case.

If you've written in a new fandom that isn't wrangled yet, we encourage you to use Unspecified Fandom as a tag to help people find your work; many works originally tagged this way now have wrangled fandoms, in which case, you can take the tag off if you wish.


As in the last post:
Commenting
Please comment on your gift(s) to let your writer know you appreciate them. Please also comment on anything else you enjoy!

Making work recommendations is a tradition. Please see more information at the participant community about where you can post your recs.

Problems
If there is something wrong with your gift or you have another concern, please contact the mods at yuletideadmin@gmail.com.

Anonymity
Yuletide is designed to be an anonymous exchange until January 1. Please don't give away what you've written. When logged in, you can, if you want, reply to comments on your own works, and you will show up as Anonymous Creator until the authors of the collection are revealed.

The Yuletide event concludes at 9pm UTC, 1 January 2026. At that time we will reveal creator names at both the main and Madness collection, and also open the new New Year's Resolution collection.

Hello, Yuletiders–as you may have noticed, the anonymous setting on the Yuletide collection, which should hide all author names until reveals on January 1st, does not seem to be working as expected, and shortly after our planned works reveals, we had an unplanned reveal of author names. We’re very sorry for this unexpected breaking of anonymity!

We’re reaching out to AO3 to help us resolve the problem. In the meantime, we have updated all works manually, and author names should now be hidden again. If you notice we have missed any, please reach out to us privately at yuletideadmin@gmail.com.

Again, our apologies–and we hope you enjoy the collection!

Yuletide Madness is scheduled to reveal at 9 PM UTC on 25 December, but this may be delayed if necessary to ensure author anonymity.

ETA: We know many of you have received email notifications to say, "The collection maintainers of Yuletide 2025 have changed the status of your work [work] to anonymous..." This is a result of us updating them manually to hide author names, in order to achieve the same effect you would expect from reveals in an ordinary Yuletide. Sorry for the confusion! You can safely ignore these notifications; we will reveal author names on January 1st, manually if we have to.

Yuletide 2025 Collection Is Live Here!


Enjoy 1539 works in 992 fandoms! (The number will go up as wranglers canonize fandoms - this will take a little time, though.)

The reveals process takes a little while to work in a collection of this size; if a story in the collection is still a mystery work an hour after opening, please let us know.


Finding works
You can find your own gifts on your AO3 gifts page: https://archiveofourown.org/users/YOUR-NAME-HERE/gifts, or by searching the box at the top of the collection works page for the full name you signed up with, or by checking your email if you get email notifications from AO3. Note: your email notifications may bundle together, and it might look like you only got one gift, when in fact you got more.

You can browse the collection by tags or by fandoms. Some fandoms are new and may not show up immediately (wranglers are working on this) or where you expect them; please check labels such as Original Work, 19th Century Historical RPF, Object and Concept Anthropomorphism, and Unspecified Fandom. More info about Unspecified Fandom here.


Anonymity
Yuletide is an anonymous exchange until creator reveals January 1. Please don't give away what you've written. When logged in, you can, if you want, reply to comments on your own works, and you will show up as Anonymous Creator until the authors of the collection are revealed.


Commenting!
Please comment on your gift(s) to let your writer(s) know you appreciate them. We also recommend commenting far and wide to spread the comment joy around! You may enjoy the challenge of a comment bingo card [update for this year's link!].

AO3 changed default comment settings last year. If you want to make sure people can comment on your gifts when they aren't logged in, you may need to change a setting on your work. More information here, under 'Your comment settings'.


Recs
Making work recommendations is a tradition. Please see more information at the participant community ([community profile] yuletide) about where you can post your recs.


Madness
For those still writing, the 2025 Yuletide Madness collection will stay open for new stories to be posted for 24 hours. It will close for posting, and open for reading, at 9pm UTC 25 December. If you're looking for prompts, there's a roundup of links here.


Problems
If there is something wrong with your gift or you have another concern, please contact the mods at yuletideadmin@gmail.com.
