    I am also pretty bad at long term goals. Specifically any kind of long term goal that doesn't get worked on every day (or at some regular interval) will just get forgotten about by me. I'm currently using Notion to create something like a Kanban board. Each item has a priority, effort size, and category. Having somewhere to put all of these goals is useful so far. It lets me see what I've been neglecting, and maybe reprioritize if I realize that I don't have time for all of the things that I want to do.

    I also like using paper to write down things I want to get myself to do in the very immediate future. The feeling of scrunching up the paper after I do my thing feels rewarding at this point.

    For long term goals I've found being social about them to be very helpful. So going running with friends, discussing books after I've read them, working on a game with a friend, etc. The commitment device of not wanting to "disappoint" a friend is a strong motivator for me.

    Based on a glance at the bip39 algorithm (which this paper is focused on), there shouldn't be a pattern in the seed phrase. Reading through the article, they show that the time required to guess the missing words scales exponentially with the number of missing words, so I don't see how this is different from brute force attacks.

    I couldn't find a link to the full paper on the website, but will have to see that to be sure.

    Truly a misc topic! Is this system of grading common in other industries as well?

    The second number (after the decimal point) represents the number after the last 9. So, 4.7 grade helium = four 9s and a 7, or 99.997%.

    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.

    This was a long video, but as someone who is primarily a programmer I found it interesting and covering a lot of topics that I had no knowledge on (and so I had to to pause the video at a lot of parts to look things up).

    • 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.

    Scraping the data feels like it's the biggest of the 4 challeneges. 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

    What else would you call it? Classical is the name of the time control. I feel like the general name would be (name of variant) + (name of time control).

    I only used the word "curated" as kind of a joke, since that's the word the creators use when pitching Nebula in YouTube videos. I think Nebula will accept anything from their partner creators onto the platform.

    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.

    I agree with your gripes. 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.

    Electron tunneling is predicted by quantum mechanics. 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.

    +1 to what @feanne said. In addition, each tile in a tilemap can be accessed by using the layer and the xy coordinate. 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.

    Do you hold the same opinion for "Rhythm of War"? 😉

    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.
