As 2025 is drawing to an end we want to express our gratitude to our Members, staff, and community for the immense work accomplished this year towards making the web work โ€” for everyone! We wish you all the best for 2026.

You can see an animated holiday greeting at: w3.org/2025/12/2025-w3c-holida

w3.org/news/2025/happy-holiday

The image features stars and the W3C logo next to a blue cartoonish fortune cat, its left paw raised and beckoning. The cat has closed eyes, is smiling, wears a collar with a bell and the large character on its belly means โ€˜good luckโ€™. The W3C logo is surrounded by text that reads โ€™The World Wide Web Consortium wishes you all the best for 2026!โ€™

Day 22 of Advent of Compiler Optimisations!

Comparing a string_view against "ABCDEFG" should call memcmp, right? Watch what Clang actually generates โ€” no function call at all, just a handful of inline instructions using some rather cunning tricks. How does it compare 7 bytes so efficiently when they don't fit in a single register?

In one hour I'm going to be interviewed by Physics Today about the arXiv's new requirement that every paper either be in English or include an English translation (blog.arxiv.org/2025/11/21/upco). What should I say?

Here's what I plan to say:

1) This policy would have ruled out important works like Grothendieck's SGA1 (arxiv.org/abs/math/0206203). It's unlikely that someone would translate a 327-page book just for the privilege of putting it on the arXiv.

2) Some scientists say now they'll switch to using HAL (hal-hprints.archives-ouvertes.), a European open-access repository that accepts articles in every language.

3) This move seems to hint at a growing "Americanization" of the arXiv, along with their September 2024 switch to no longer supporting mirror websites in countries outside the US (blog.arxiv.org/2024/09/13/atte). It seems the arXiv is planning to move their storage from Cornell University to a "Google cloud platform" (telescoper.blog/2025/04/24/arx). Europeans responded by creating a "dark archive" for the arXiv: a backup that's not publicly accessible but can be brought online if the forces of evil crush the US arXiv (telescoper.blog/2025/05/14/an-).

4) It's a separate issue, but Physics Today should be aware that the arXiv is getting lots of AI slop papers. Maybe a topic for another article!
