This was my first time trying working with a laser cutter! I wanted to make a house warming gift, and thought that this could be a nice way to get familiar with the laser cutter. The house warming gift was the mistborn wheel. But after I made that I kinda of caught the itch and wanted to make something for myself as well, which ended up being the surgebinding chart (second design).

I made this a separate post so that it could be searchable when people look for other Cosmere stuff on Tildes.17 votes -

- Learning that Linux (or whatever OS) doesn't control all of the computer, but instead this tiny part of the computer was news to me.
- Cross SoC attacks are a scary and interesting idea.
- As a sidenote, I read the description of the video and saw a brief note about Barrelfish, the multikernel OS. Which I thought was a fascinating idea for dealing with scaling operating systems to work with computers that have many many cores which don't have equal bandwidth access to all parts of the RAM.

From a brief glance at the website I think going through all the country codes and visiting the URL -> https://cdn.henleyglobal.com/storage/app/media/HPI/AD_visa_full.pdf and then somehow parsing the PDF is the best idea I can think of.
But once you have the data, say as a 2d array indexed on the countries, it seemed to be that this was a known problem. Using chatGPT I found out that this problem is the optimization version of the set cover problem. wiki link

It's exactly what you said about any person bring able to upload to YouTube. Nebula on the other hand has a very small and profitable group of uploaders.

But if you've done the previous years of Advent of Code, you'll see there is (IMO) at least 1 problem every year, where making certain assumptions about the input allow you to solve the problem in a trivial amount of time. That wouldn't work for a general arbitrary input.
I dislike it as well but it's not unexpected for Advent of Code.

Short version is that solid state semiconductors require understanding of surface states, which requires QM
TIL!

And while not exploited by semiconductor design, it is a relevant factor because the transistors are getting so small that these quantum effects need to be considered. So without quantum theory, maybe we have a lot of semiconductor people scratching their heads?

If you're fine with reading large books, I think you should read the prologues to Way of Kings to see if that has you hooked. Otherwise, Warbreaker I think is a great entry point.

To store data for each tile I'd simply create a dictionary where the key is a Vector2i and the value is a struct/class containing your data. Note that assuming you havr a dense square grid, a 2d array would be the best solution. But I find it quicker to bang out code with a dictionary.
HTH if you have further questions.

Spoilers for RoW
IIRC we only learn about the pure tones and the various mixures of Investiture near the end of the book. And that's also around when the Rhythm of War is created by Navani. Similarly here, we only really learn about the Dawnshards at the end of the book. The book also isn't about the Rhythm of War. But a similar concept is used to create the anti-stormlight which is then used to kill Teft's spren. -

My entry in to the Cosmere started with Way of Kings (around the same time last year), and I read all the way through to Rhythm of War without realising that there even were novellas. The only books I have left to read in the cosmere are White Sands and Yumi and the Nightmare Painter. At least based on this bibliography.
+1 to a novella about Rock. I'd love to learn more about the ways of the Horneaters. Also it was probably obvious from its earlier description, but I gasped when they spelled it out in this book that the Horneater Peak contains Cultivation's perpendicularity.

Spoiler warning for Dawnshard and previous Stormlight Archive books (Way of Kings, Words of Radiance, Edgedancer, & Oathbringer).
I'd seen mentions of the sleepless and Dawnshards when browsing the Arcanum and so was primarily hoping to learn more about these in this book. But in a short period of time I was surprised with how attached I grew to Rysn! In particular at the end of the book when the captain appreciates Rysn's role as Rebsk and allow here to steer the ship (showing their trust) for a few minutes, I let out an audible cheer. (Also when I noticed that she gained perfect pitch and perfect color recognition) Rysn and Vstim's interludes in the previous stormlight books were some of my favourite interludes and I'm so glad that we got to see more of them here.
The other thing I was surprised by was the set up for the two Winderunners swearing their third ideal here. Lopen says quite clearly that the third ideal is saying that you will protect even those you hate. And then a few chapters later we see Huio swear the third ideal in order to protect Lopen. I honestly thought this was just going to be played off as a joke since they have a fair bit of banter early in the book. But I was heart warmed to see that realisation that Lopen has that his jokes and teasing hurt people, and him swearing his own version of the ideal to protect other people from himself. It reminded me of some of the similar (but not same) character development moments we get with Wayne in Mistborn.
I'd love to hear what other people who read this book thought about it as well. Once I can get my hands on Yumi and the Nightmare Painter in paperback form, I hope to discuss that too with all you Cosmerenauts!

This platform is like one big show and tell, and you can't just be showing.
Ps: I do love LeagleEagle and his videos.
Truly a misc topic! Is this system of grading common in other industries as well?
