-- Paraphrased from The Restaurant at the End of the Universe by Douglas Adams

I was recently at the kiosk at an Odeon cinema in Norway and I noticed that their popcorn buckets were helpfully labeled S, M, and L. Stor, Middels, Liten. No X-sizes in that case though. At least with popcorn you can plainly see that S is much bigger than L is when you pick it up yourself.

It's a fun read in a fan-fiction sense, but when you look at the out-of-universe story of the events of Tolkien's life and his writing process it becomes clear that Tom is not meant to be any kind of evil.

Tolkien wrote a silly whimsical poem about one of his children's toys that they had named Tom Bombadil. In this tale he lives in a dangerous environment, but he is able to overcome the dangers and get his happy ending.

When Tolkien later was writing LotR, he drew upon his former work and put in the silly whimsical Tom as an early encounter for the Hobbits just as they are leaving the Shire and starting their adventure. This story arc delivers some early exposition about the world in his dialogue, it shows that the Hobbits are hopelessly unprepared to stand up against any foe such as Old Man Willow or the Barrow-Wight and need rescue (this way they can have character growth and become Heroes by the time they return to the Shire) and it gets the Hobbits armed for their quest towards Rivendell (and most importantly to put the right kind of blade into Pippin's hands for later).

In a more thematic sense he is just part of nature, not evil but also not actively looking to do good, just existing. He is master of his domain in the same sense a big moose might be the "master" of his local forest, he's the biggest around and isn't threatened by anything else, but he has no human desire for expansion and doesn't push back when civilization comes around to turn the land nearby into farmland either, just keeps to himself. He doesn't try to tame the angry trees because it's just protecting it's territory, as is natural, nor does he try to "exorcise" the barrows because nature doesn't actively go about trying to undo the evils created by man.

That's a neat observation, the cities do have a similar history.

The medieval town called Oslo burned down in 1624, and a new city was founded on the other side of the bay. It was named Christiania after the monarch Christian. It kept that name until 1925 when they changed it back to the old historical name Oslo.

Some decades later, the Russian monarch Peter would also found a new city, which happened to have his name in it. So these two cities were being constructed at around the same time and taking design and architectural inspirations from the same places I would imagine.

One time I was using my laptop to remote desktop into a computer I was hundreds of km away from physically, I discovered that if I hit the power key on the laptop (yes, the laptop had a key on the keyboard for power, not a separate power button) while having the remote session window focused, it sent the signal over the wire and put the remote host to sleep instead. Whoops.

After that I looked up how to enable wake-on-lan and open up a port to be able to do that remotely.

I rediscovered the joy of working with databases while working on an Elixir application with a Postgres/Timescale DB. Elixir's Ecto library (doesn't really fit the definition of an ORM) lets me compose queries in a functional syntax that then get compiled to SQL before execution. This both enables me to be more productive and results in more readable code that can be reasoned about and be tested easily. Sometimes I still have to dive into "raw" SQL to write e.g. a procedure or a view definition (like Timescale's continuous aggregates), and I definitely miss the pipeline operator when those expressions get complex. SQL is a powerful tool, but it gets clunky and has strange footguns. A feature like what this post describes is definitely a step in the right direction for Postgres. Looking forward to try it out.

This looks very interesting! I only skimmed the abstract now, but I will look more closely tomorrow. Back in 2016-17 I did a master's thesis on a combination of (much simpler) cellular automata and neuroevolution, and had some thoughts about how other neural "paradigms" like backpropagated deep nets and indeed, adversarial training could be used with CAs. It's great to see that it's an ongoing topic of research.

This is a difficult problem indeed, but thankfully it is just as difficult for the malicious actors as it is for the "good guys". Since various bad guys have presumably been scanning public repos for years already, Github and PyPa adding this feature is leveling the playing field, even if it is not a 100% accurate search algorithm.
