  • "The Open Book is my long-standing attempt to design a comprehensible and accessible e-book reader that you can build yourself (or at least have manufactured affordably). The current edition is something I’m calling the “Abridged” or “Developer Preview” edition. It’s designed to be incredibly simple: there are 7 through-hole and 14 surface mount components, nearly all in a chunky 1206 package that’s easy to hand solder. The tradeoff is that it has no LiPo charging circuit; instead it uses AAA batteries, making it a bit more chunky than previous versions of the book.

    The goal with this version is to get hardware in hands so we can start hacking on firmware."

    So:

    • This is a hobby / project of love
    • The current focus is on hardware

    I’m sure that the eventual plan is to support ePub.

    I’m not sure it will ever get there, because it’s not a well resourced project, but I personally don’t like criticizing one person’s efforts, which they are making freely available.

    I’ve ended up using calculus and trig for programming multiple times.

    You may be able to draw a circle without math, but teaching a computer to draw a circle requires an understanding of math.

    All of machine learning is rooted in linear algebra, rust is a very practical programming language that gains most of its power through category theory.

    You don’t need to know high level math to be a successful developer, but it can really help in many areas. I can’t really think of how to categorize which areas high level math is more or less likely to show up in, which I guess itself kind of supports my point.

    Just understanding what a derivative is and what an integral is can help you determine what problems are solvable and what aren’t, and let you think ahead about what information you might want to hold onto in your data structures. ( Think about what the +C in this integral represents in the real world, and what data you need to pin that down concretely ).



  • I tried to solve these cross-distro compatibility problems in a generic way with this “standard”, more years ago than I’d like to think about:

    https://www.supergrubdisk.org/wiki/Loopback.cfg

    If someone wants to come up with a bootloader agnostic solution rather than one tied to grub, like an extension to Bootloader spec , https://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/ , I’d be happy to evangelize it and add support to grub for using it.

    I’m not aware of any other bootloader that supports reading a config file that exists within an iso though, and secure boot support may add additional complications.

    Bottom line:

    I feel like we could relatively easily get to a point where every Live iso that actually supports loop booting can just be added, as a file, to your USB drive (from Windows, or your android phone even) and be detected at boot in a nice little menu, no editing of config files needed.

    I don’t have the time or spoons to get the Linux community there alone, but if people are interested in helping I’m more than happy to pick this up again.

    (Note: Please don’t blindly suggest “Just chain load the iso!” Things aren’t that easy, unfortunately).

    Sorry again. I wrote this last comment (and this one, TBH) from my phone and “–iso=s” should have been “–iso-8601=s” . I’ve edited my comment and the command should now work (Making a backup of your grub.cfg containing the date, to the second, in the filename. I did that to hopefully avoid you running the same command again after trying some fixes and accidentally clobbering your backup).


  • Or you can recruit heavily in areas where folks are disadvantaged and have few options, dangling education in front of them in exchange for being willing to kill or die for you.

    This is absolutely what we do in the U.S. and it’s abhorrent.

    I guess what I want is for nobody to be so desperate for their basic needs that they feel compelled to kill and die in war.

    And if we had a country that cared for all of its citizens and didn’t start wars of aggression, maybe more people would want to enlist as they have real values to protect and have a reasonable expectation that they won’t be committing atrocities?

    Honestly not a criticism of you or your comment. Lot’s of people are advocating for the same thing; You just said it plainly.

    …Anyway, this is all terrible and we absolutely can do better, starting with building community locally, mutual aid, protesting, and listening to marginalized and oppressed people’s.
