    To back up what you’re saying, I work with ML, and the guy next to me does ML for traffic signal controllers. He basically established the benchmark for traffic signal simulators for reinforcement learning.

    Nothing works. All of the cutting edge reinforment algorithms, all the existing publications, some of which train for months, all perform worse than “fixed policy” controllers. The issue isn’t the brains of the system, its the fact that stoplights are fricken blind to what is happing.

    Yeah, university is almost certainly going to expect you to be able to install Unreal or Unity, which just isn’t possible AFAIK on NixOS. NixOS is very all or nothing. You can’t just remove the restrictions for one project and hack something together to hit an assignment deadline. Theres still lots of pain points with LD_PATH and 3rd party binaries.

    That said, you can use nixpkgs on non-nixos and still get reliability for Godot and other open source tools. For your case, I highly recommend dual booting, and then using nixpkgs without going full blown nixOS.

    The abbreviation method LessPass uses works pretty well. Its usually only a problem with a re-branding, like how wefwef changed to voyager. When that happens it’s not too big of a deal, I just change it to the new thing.

    What is a big problem with the URL though is login portals. Like when it’s some conglomerated system that involves a million redirects, and/or a “login with XYZ”. They can get some really weird URLs that have nothing to do with the actual site and those are a real pain.

    #3 isn’t true. There’s a username field, so you just put in the username of the alt accounts.

    Your point about the master password and two factor is a good one though.

    In practice password restrictions are rare (like 1% of sites), but they are problematic when they happen because there’s so many different ways to restrict passwords and trying all combinations is impractical. Needing the counter is exceedingly rare. Remembering the username isn’t a problem, but if you don’t have a consistent policy of always-using-a-username or always-using-the-email (as the lesspass username) it can be difficult to remember that. Similar situation with the URL, if it’s not abbreviated consistently, then it’s a problem.

    That said, I still use LessPass for everything and just deal with the edgecase problems.

    Despite what others are saying, I’ve been using it for a couple years and it can work great if you’re okay with the trade-offs.

    Of the three (Integrity, Confidentiality, Availability) it has better availability than cloud storage which is what I care about. Even when the LessPass site is down, there’s an IPFS version, mirrors, local cache, etc so it’s basically always possible to derive any password.

    At a user level, it’s very impractical (and a slight risk) to always retype the master password at every single login screen. However, letting the local autofill save the password doesn’t defeat the point of LessPass. Why? because, if you only use local storage, and you’re traveling and your phone breaks, you’re now locked out of every account. With LessPass, you’re fine as soon as you get an internet connection.

    There are a few caveats.

    • There’s no global 2factor. Loosing the master password means every site that doesn’t have its own 2factor is instantly fully exposed.
    • I do agree there are a few sites where the default options don’t work because of the character restrictions. It’s about 1.2% of websites in my experience, but they are painful exceptions. Basically you have to rely on memory to be able to pick those same settings again. I recently wish there was a unified dataset of which websites had password requirements, and then LessPass would auto check the necessary boxes when the website URL was pasted in. Maybe one day.
    • Changing your master password requires changing every single website. If you don’t, then it’s impractical to remember what password was used for what site.
