Subject: [PATCH] Make the atom feed always include an updated element

Contrary to my expectations, <updated> is the mandatory tag, and
<published> is the optional one. I think this reflects the fact that
they consider the first publication to also be an update, and the
published is just if you want to distinguish a different date? Anyway.

+
+This year I went to the LLVM Dev Meeting (Oct 22–24), officially sponsored to do so for work!
+
+It was just across town, but I had to wake up early and it was far enough away that I didn't want to take an hour long bus ride at 7am, so I felt forced to use Lyft.
+
+I was only one of like 4 people total I saw with a mask, which is annoying.
+It wasn't very connected with outside, although there was outside seating for all the meals which made things managable for me.
+I definitely ended up somewhat dehydrated because of this though.
+
+It was nice to talk to people!
+I liked talking with coworkers in a different environment, got to hear new things that way. (I miss the

+
+Getting to meet [John Regehr](https://john.regehr.org/) in person was very nice!
+A highlight of the event because we've talked a bit on twitter and mastodon for ages.
+
+I discovered that my old personal laptop (the 2-core 8GB 2015 MBP I'm writing this post on) takes roughly two full charges to do a clean compile of clang.
+I wanted to experiment with something but had a year-old build of LLVM, I started compiling at full battery, discharged to 10%, charged back to full, and discharged back to 20% by the time compilation finally finished.
+
+I got 3 LLVM t-shirts, one is the conference shirt, two were just LLVM merch from the stand.
+My favorite is the shirt of Jessica's LLVM dragon book design.

+
+My favorite talk was the one on [Lean-MLIR][], which showed a nice setup for formally verifying peephole optimizations.
+They seem to have a [nice online playground setup][lean-mlir-playground], I really want to play around with proving some optimizations with it.
