  • It’s awesome! I used FreeCAD and OpenSCAD before and I think I will stick to solvespace for new projects. FreeCAD is OK but quite buggy and the parametric design is a pain. OpenSCAD is also great and I still use it for some things. I think parametric design is cool, but 99/100 times it is completely unnecessary for me and solvespace made me realize this. I initially disliked being unable to define variables for dimensions (and re-using them) but again it’s often overkill and disrupts the flow quite a bit, so suddenly you would spend hours defining parameters and calculations that you wouldn’t use anyways. TLDR: YAGNI basically. Also, solvespace is pretty :) What about you?

    Don’t really have a clue about e-bikes. But looking through some e-bike chargers on Amazon, they have maybe 100 W to 200 W. USB-PD (EPR) apparently supports up to 240 W. Do note that the e-bike chargers are rated at 54.6 V, though, while PD only supports up to 48 V, and I guess the higher voltage might be required for the cell chemistry. So idk if it would be possible to design your batteries around the USB spec. In any case, you would need a separate charger and special cable to support 5 A over USB anyways.


  • This is the classical understanding of it. Determinism basically says “given some initial state of the universe, you can pre-determine the end state before it happened”. E.g. there would be enough information at any point in the timeline of the universe before the 9/11 terrorist attack to infer that it will happen, just like with your coin flip example. So the question becomes whether true randomness exists. If it does, then it will have a major say in how the universe evolves between its beginning and 9/11, due to how chaotic systems work. Your coin flip example is a typical argument against true randomness, but modern quantum mechanics challenge this point of view, opening up some more interpretations. I suggest the Wikipedia article on Determinism. It has some very interesting points.







  • Absolutely! These are the obvious ones, maybe you already know them:

    • T-Square
      • “TRUTH” is an absolute classic, just like “サーキットの放浪者”, and “Travellers”
    • Casiopea
      • I think “Be” is my favourite Album, but all are solid
    • Masayoshi Takanaka

    And then also some that are maybe lesser known (no particular order):

    • Katsumi Horii Project
      • They have quite a lot of songs. “Way to morning” or “Flashback” are good examples. I also like “Jungle of Heaven”
    • Trix
      • “ECCENTRIX” is really nice, just like “An Index”
    • Dimension
    • Himiko Kikuchi
    • Naniwa Express
    • Yuji Toriyama
    • Chikara Ueda & The Power Station
    • Toshiki Kadomatsu
    • The Gran Turismo soundtrack also has some hidden Gems here and there

    I think what I like about this genre is that it combines very catchy melodies/riffs and chord progressions with really creative jazzy solos. I have not really found much recent stuff (>2010), though. But I can recommend SOIL & Pimp Sessions. They are more recent and more traditional-jazz-oriented.

    Bonus if you like light prog/math rock: Check out Elephant Gym. Spring Rain (春雨) is one of my favourite songs.




  • At work, I have a very knowledgeable colleague who is quite the Linux nerd. I have been moved into their department and I feel like they never had the chance to share all of their accumulated knowledge with someone, so they kinda dump it onto me and every little question has the chance to become a lecture. I am very thankful for it though, because I get learn a ton but sometimes you just wanna get a bool, without learning kernel internals that are absolutely not related to the question
