  • It really depends how the release turns out. Eye tracking is often used in social VR games like VRChat, and it can help increase peformance, but that often requires setup. The other “features” are not standard or completely lacking in PC VR, like “headset feedback” or adaptive triggers. These wouldn’t be used in any games even if the hardware/software was capable of it.

    Compared to the Valve Index, the PSVR2 has a higher screen resolution, OLED, no finger tracking (different controllers), and inside-out tracking instead of base station tracking. It looks like a really good option, at a really good price (compared to other “consumer” PC VR headets like the Index). From what I can tell, you’re not really “missing” any major hardware features when using PSVR2 on a PC compared to an Index (depends on implementation, will be obvious at release). Although the lack of eye tracking when the hardware is capable is kind of a bummer.

    Wait this one out for initial reviews, but if those are good, the PSVR2 seems like a very good option for PC VR (Although only “casual”, like playing games, social vr, etc. compared to “competitive” like very high level play at Beat Saber, shooters, etc).

    Do note that this is just looking at PC VR exclusive headsets. “Standalone” headsets like the Meta Quest lineup offer similar VR hardware specs at a similar or lower cost. These come with the downside of having to “stream” from a PC rather than using raw display output (for games not natively supported on the headset). The privacy aspect of standalone headsets needs to be considered too. Most run a version of Android, which comes with just as much (or more) telemetry as an average Android smartphone.

    As for being tethered, you get used to it pretty quickly. The main problem is that the cable is being used, and will break after some time. They are often expensive to replace, like on the Index. With standalone headsets, the cable is often USB-C and a lot cheaper to replace. I don’t know how replacement cables for the PSVR2 are handled.





  • It’s used often by novices, because outdated articles keep telling them it’s “the best Linux distro”. Canonical has gotten very corporate over the last several years, forcing things like snap onto users. Ubuntu used to be the number one user friendly distro, now they shove ads in the terminal. It’s not getting hate for being easy to use, it’s getting hate for marketing itself as such, then forcing corporate bs on the user (who are often new to Linux). Many other user-friendly distros have not seen the same amount of hate, because they aren’t objectively bad.


  • I recommend against using Manjaro, it is poorly maintained and has many downsides compared to something like EndeavourOS (which has a similar goal to manjaro with less downsides).

    If you’re comfortable using a specific package manager, go with a distro that uses that package manager. If you’re already familiar with Mint, something else Debian based might suit your needs.

    If you’re still looking for the distro that’s right for you, make sure to separate your / and /home into different partitions during your next installation. This allows you to switch distros while keeping all your documents and personal files.

    If you’re unsure which distro to try next, https://distrochooser.de/ gives you a set of questions and ranks distros on what would fit best to your needs.


  • This isn’t about “making the game work”, or “adding Linux support”. This is about toggling a checkbox to stop explicitly preventing Linux from working.

    The games that already did never faced a massive cheater problem because of it. The games that have stopped development long ago or “don’t care about Linux” (without preventing it with anti cheat) were still made playable by Wine and Proton.

    If the developer wants, they can add system info to their ticket system and filter out any Linux tickets. It costs a game developer barely anything to decide to allow Linux users. Linux support costs a lot, but valve, wine, and the community has been putting a lot of effort in so game developers don’t have to change anything about their game.


  • Some programs may use libraries or tools specific to a distributions package manager. For example, yay, an AUR helper/pacman wrapper. You would have a very hard time getting it to work on Debian.

    Other programs might only include build scripts for a distro specific build system. For example, a program might skip using a Makefile, and do everything in the Arch-specific PKGBUILD.

    Generally though, most software uses a standard cross-distro (or even OS) build system. In this case, compiling from source would be an option on any distro. The program might still only be packaged for Arch/NixOS/Gentoo (or others), as it is a very simple process to do so.


  • The times I calculated were indeed going over every possible combination, it would take half as long to crack a password on average. Considering reducing the time to 1/1000000 still leaves you with an incomprehensibly large estimated timespan, dividing that by 2 doesn’t do that much for making it brute-forceable.

    I did note it was specifically for 8 emojis, not 8 characters or bytes.

    And yes, it’s very impractical and likely to break things. It’s better and much easier to add extra letters, numbers, and symbols to your password rather than using emojis. Using a password manager is even better.

    As you stated, a single unicode character would mean your password wouldn’t be included with the potential options in almost all brute forcing tools. Whether you use 8 emojis or 1, your password likely won’t get brute forced.

    All of my “emoji password” numbers are if the attacker knows it’s a password containing exactly 8 emojis, and nothing more. Adding a regular symbols+upper+lower+numbers 16 character password would make it even more impossible to brute force.


  • For somewhat more realistic numbers:

    According to minerstat.com, an NVidia RTX 4090 has a hashrate of 118.07MH/s. This is 118.07 Megahashes per second, or 118.070.000 hashes per second. For a password with only 8 lowercase letters (208.827.064.576 combinations), it would take an RTX 4090 approximately 1769 seconds (or ~30 minutes) to go through all possible combinations. For an 8 character upper+lower+numbers password (218340105584896 combinations) it would take 1849243 seconds, or 21.4 days.

    For an 8 emoji password (32482071647592311234920185856 combinations), it would take 275.108.593.610.504.896.512 seconds, or 8.723.636.276.335 years.

    Lets say a magic prediction algorithm reduces the number of possible combinations in each password to 1 out of every 1 million previously possible combinations. 8 lowercase letters would be cracked instantly, while an 8 emoji password would still take 8.723.636 years.


  • NordPass is completely incorrect on the "it makes a password easier to “crack” thing.

    I absolutely don’t recommend using emojis in your password, as it is far too easy to get locked out. However, a password containing an emoji is significantly harder to crack.

    Hashing is a process used to calculate a large number based on some input data. If the input is the same, the output is the same. If the input differs just slightly, the output is completely different. This process is mathematically irreversible. Since this (and other techniques) is often used for passwords, to “crack”/bruteforce a password, the attacker has to go through every possible combination of input data, calculate the hash, and check if the hash is the same as the password hash.

    To make the process of bruteforcing a hash quicker, an attacker often makes assumptions about the input data. If they know a password contains 8 characters, and only lowercase letters, this massively narrows down the amount of passwords that need to be hashed and checked. If they know the password contains someones birth year, that too reduces the time to bruteforce a password.

    The more possible characters you have per position in your password, the longer it will take to bruteforce. An 8 character password with just lowercase letters has 208.827.064.576 possible combinations. This sounds like a lot, but it’s often bruteforced rather quickly. Adding uppercase letters and numbers to that, we’re already at 218.340.105.584.896 possible combinations. That’s ~1000x more combinations, and that’s for 8 characters. It’s the difference between bruteforcing taking a day, and taking 1000 days. (Do note an 8 characters lowercase password probably only takes like a few seconds to minutes, not a full day.)

    According to https://emojipedia.org/stats there are 3664 different emojis. Lets say we create an 8 emoji password. (some emojis aren’t one character internally, the same principle still applies.) Just 8 completely randomly chosen emojis. That password would have 32.482.071.647.592.311.234.920.185.856 different possible combinations. That is about 148.768.232.755.857 times more combinations than an 8 character uppercase+lowercase+numbers password. That is the difference between bruteforcing taking a day or taking 407584199331 years.

    The same things as non-emoji passwords still apply, you can make assumptions about which emojis are used. People aren’t entirely random, so chances are higher they used some of the more common emojis. However, that is similar to prioritizing the letter “e” because it is more common. Yes, it’ll probably reduce the time taken to bruteforce a bunch of passwords, but it’s not set in stone that every password will even contain the letter “e”.

    Again, due to the potential of breaking things, locking yourself out, etc. I DO NOT recommend using emojis. Use a password manager with longer passwords.

    However, including an emoji in your password makes it significantly more difficult to bruteforce. As the assumption that the characters in your password are letters, numbers, and symbols no longer holds, which drastically increases the possible number of combinations.



  • Depending on the application you used to alert you of the AirTag, it’s possible that your phone did not send location data back to Apple.

    Apple can track AirTags, because iPhones are programmed to listen for them over Bluetooth Low Energy, and send the ID of the AirTag and location data of the device to Apple.

    If your Android phone has an application to listen for BLE devices in the background, keeping track (locally) of which devices it saw in what locations, that application can tell you if you’re travelling with an AirTag (or similar device). It might even be able to interact with the AirTag, such as making it beep or reading its ID. If that application doesn’t send your location to Apple, the AirTag was not able to use your phone to make its location known to the owner.

    Therefore, to the owner, AirTags are useless unless an iPhone (or other device that sends its location to Apple) is around.

    I can personally vouch for how toxic the Discord server and its moderators/admins are. Went there for support (Hyprland was crashing on startup on AMD, sway worked fine), and was told something along the lines of “if you can’t figure this out you’re stupid and you should stop using Linux”. Figured out the issue on my own and stopped using and recommending Hyprland after that.


  • You either have broken permissions, or a broken drive.

    Try going into a terminal as your user, not root, and try creating a file in the directory you want to use for your Steam games. touch filename can be used to create files. If it spits back an error about permissions, you likely need to change ownership of the directory to your user. This would be sudo chown -R username:username /path/to/games/directory Make sure to only run this on a directory that’s not used for anything else, as it can break system components if you run it on the wrong files.

    If, when creating a file, you instead get a “Read only filesystem” or similar error, your external drive might be broken. This would be a whole separate thing to troubleshoot, and you’ll have to look up your specific error for further actions.


  • For a distribution like Fedora, it’s usually not required to turn off secure boot. You’ll know if it’s needed when booting the install USB, as it’ll give a “security policy” (or similar) warning.

    Other things of note when dual booting are Windows “Fast Boot” and “Hibernation” features, which can put hardware in a state where it is unusable from Linux. Turning those off in Windows can fix things like your network interface not working. Windows also stores the time in a different way than Linux, if you are in a non-utc timezone, setting up NTP (automatically syncing date and time) on both Windows and Linux can help.


  • VRChat in particular has been degrading in quality and experience ever since they needed to start pleasing investors. You can give it a try if you want, but there’s a lot of toxicity there. Platforms like ChilloutVR or NeosVR have a better (but smaller) community.

    Although some titles like BONELAB or Pavlov do feel a lot more like “tech demos”, they are still great titles. Some desktop titles also have VR ports that are worth playing, No Mans Sky and The Talos Principle come to mind.

    The modding scenes of a lot of games have good VR mods too, “Vivecraft”, if you’re into Minecraft. Subnautica has a good VR mod, Half-Life 2, Deep Rock Galactic, Outer Wilds, and much more.


  • Lets take the imaginary program Y. It is free open source software with the GPLv3 license. If Valve wants to include Y in SteamOS, they are free to do so. Any time Valve makes changes or fixes to Y, they are legally required to provide the source code of their changes, as stated in the GPL license included with Y.

    A lot of programs have this license (or a similar one), which forces corporations to contribute back to FOSS projects.

    Some Valve-made components in SteamOS are truly “SteamOS only”, but a good amount of fixes to non-Valve programs are submitted “upstream” (to the original project). Due to the nature of Linux, it might be possible to copy the few non-foss components in SteamOS and directly use them in another distro.

    Alongside forced contributions due to licensing, Valve contributes a lot of code to “gaming” programs on Linux, such as Wine or DXVK. They also make some SteamOS components FOSS, including Gamescope for example. Valve is (currently) doing a lot of work “for the community” rather than for direct profit.

    Mainly their creation of Proton, and contributions to DXVK and WINE have helped Linux gaming become possible on any distro.
