  • Someone I personally knew almost gave up on Linux because their mint install would have screen tearing issues due to an outdated driver module and kernel, since Mint follows close to Ubuntu’s kernel releases which are slow.

    Cutting edge and bleeding edge kernels is one of Linux’s biggest strengths because 99% of driver modules are in the kernel, so keeping it up to date will significantly reduce the chances of issues with your hardware, especially if its anything new.

    You dont need to know the version, but knowing that your updates are based on cutting edge latest stable is what can save you from driver headaches.



  • Do these updates not go through any rigorous testing at all

    Lol no, MSFT infamously dropped their entire Hardware QA team after WIndows 7 and instead relied on the also infamous insider hub to get QA “feedback” from home users instead, leading to the also infamous Windows 8 disaster and slightly less infamous critical CVEs that went unaddressed because MSFT ddidn’t even bother to read the insider hub posts.

    Oh and they didn’t learn anything and kept running with the insider hub well into Windows 10 & 11.










  • This one is funny because it 100% still exists somewhere, but I haven’t had the chance to verify it again.

    Okay so basically its a data recorder box (ex: brainbox) that connects to a bunch of industrial sensors and sends the data over the network with your preferred method.

    Builtin firmware gives you an HTTP webui to login and configure the device, with a user # and password.

    I think the user itself had a builtin default admin which was #0, which everyone uses since there wasn’t really much use for other users.

    Anyway, I was looking at the small JS code for the webui and noticed it had an MD5 hashing code that was very detailed with comments. It carefully laid out each operation, and explained each step to generate a hash, and then even why hashes should be used for passwords.

    Here’s the kicker: It was all client side JS, so the login page would take your password, hash it, and then send the hash over plaintext HTTP POST to the server, where it would be authenticated.

    Meaning you could just mitm the connection to grab the hash, and then login with the hash.

    I sat there for like 10 minutes looking at the request over and over again. Like someone was smart enough to think “hey let’s use password hashing to keep this secure” and then proceeded to use it in the compleltly wrong way. And not even part of like a challenge/handshake where the server gives you a token to hash with. Just straight up MD5(password).

    It was so funny because there were like a hundred of these on a network, so getting a valid hash was laughably easy.

    I never got to check if this was fixed in a newer firmware version.


  • Lots of games that ship with kernel level anticheat have an android port that doesn’t have that feature because android (also linux) similarly doesn’t hand out root access, let alone kernel access to anything in userland.

    Huge example being Fortnite.

    Already ignoring the fact that kernel level anticheats have well known bypasses, cheaters can also just use the Android version to make cheating easier if that was really an obstacle.

    Anyone peddling kernel anticheat as a requirement is just using it to cut costs in running moderation staff. Epic Games specifically is just being a dick to linux because they know they have zero leverage in that market, and don’t want to give Steam more traffic.

    All Valve really has to do is sell enough units to tip the percent of linux users that these publishers would not want to miss out on. That’s how so many updated and expanded with the steam deck. Currently the estimate is about 4 million monthly active users on a linux platform. I think if they can reach 10 million (I think 6-7%), it would be enough to incentivize the change.

    I never would have thought Microsoft would allow Halo Infinite or MCC on linux 5 years ago, but they actually changed their minds because they knew people wanted to play on the steam deck. I would even take a guess that the new CoD stuff will shortly follow since MSFT is taking a more open platform approach anyway.
