    FWIW I run Ubuntu and do some gaming. Haven’t hit any issues, and I’ve run multiple AAA games on release (TLOU, Indiana Jones, Hogwarts Legacy, GoW 2018) as well as other, lighter, titles like Cities Skylines 2, Asetto Corsa, Project Cars, American Truck Simulator

    I’m sure there are bugs that I haven’t experienced, and my system is probably newer/higher performance than the average person + i chose parts with Linux in mind. But based on my experience, I wouldn’t tell someone to jump into a less user friendly distro because of problems I myself haven’t run into. Much better to try one, see if you hit an issue, then jump rather than doing the hard one up front


  • Consider your library: most games will be able to run fine on Linux. However, if you predominantly play online multiplayer games which require anticheat you should check compatibility on ProtonDB.

    Second, consider your hardware: if your GPU is AMD you’re good to go. Nvidia might have issues (not sure if this has been resolved since I last had to look into it).

    Finally, choose a distro: I’d recommend Ubuntu or anything Ubuntu-based. There’s a lot of mixed answers in the Linux community and definitely a ton of hate for Ubuntu. However, as someone who has been running Linux for nearly a decade at this point, there are a few key points:

    1. Ubuntu is debian based, so it’s extremely stable(but not as slow to update)

    2. Ubuntu is very beginner friendly, and you won’t need to touch the terminal if you don’t want to

    3. Everyone hates on snaps, but for you I don’t think you’ll run into an issue with it.

    Personally, I steer towards debian based distros for my devices as well because I’d rather spend time messing with the software I’m running or other things NOT debugging why my config is suddenly shitting the bed


  • Definitely, and I’ll never try and make the argument against that. However what they did was definitely a significant improvement on these pre-existing translation layers.

    Linux gaming can be clearly defined as pre-proton and post-proton because it was such a huge improvement to the experience (one-click installs, large number of support in games, gaming via proton counting as a Linux sale in publisher metrics, etc)

    And I’m speaking from personal experience, before proton I had a hard time getting pretty much every game I tried to play working on Linux (and tbf a large part of this is probably me fumbling the installation but I’m not an untechnical person either, so I’m sure this was the experience for many)



    1. Android is, at its core, an open source mobile operating system. What Google has done with it is monopolize all of the software for the platform. There are competitors (read: GrapheneOS, F-Droid) which are also based on the Android Operating System but outcompeted by Googles market position

    2. iOS shouldn’t even be in this conversation, not open source & completely walled garden

    3. “Whataboutism seems to be an admission of truth these days” HUH? At what point did I engage in whataboutism, i simply pointed to other companies that have set standards for gaming accessibility in the market.

    Valve:

    1. Has Steam, the largest videogame platform on PC. You claim it’s a monopoly but it’s not because it has direct competitors in Epic Games (Fortnite is not a small game), Riot Games (League and Valorant are not small games), Battle.net (WoW, Hearthstone, Overwatch are not small games), etc

    2. Developed the proton translation layer (which you yourself made this post for), and released it open source so anyone can use it. I myself leverage Proton for Linux gaming on a daily basis (I do NOT run SteamOS)

    3. Released SteamOS, which is a fork of Arch Linux, as a means of helping gamers break away from the real monopoly of Microsoft/Windows

    4. Is not creating a walled garden the likes of which we have seen in every xbox, playstation, and nintendo console. If Epic, Riot, Blizzard, etc wanted to release a launcher for Linux (and subsequently SteamOS) they could. They just choose not to, because they feel it doesn’t make financial sense for them to do that.

    Okay so I’ll try my best to convey what I know (I studied DFIR in college, but I work as a security engineer now):

    There are two types of mobile device forensic acquisitions/collections/extractions: BFU and AFU.

    BFU (Before first unlock) extractions simply refer to what Cellebrite is able to pull from the phone when it has been turned on but not unlocked for the first time, similarly AFU (after first unlock) is what it can collect after its been unlocked.

    You can think about this as your phone being in two states: when you first boot it up (and I’m talking from the Android perspective, because I have never owned an iPhone) you’re required to use your pin/password to unlock the device and then it will complete its boot. Any time after that first unlock though, you can unlock with stuff like biometrics and its much faster (i know my phone when i unlock for the first time after a boot will display an “Android is Starting” or something like that while it loads up).

    Bringing this back to your main question: depending on the OS version and device, what is pulled from AFU/BFU will vary. So looking at the image you linked:

    If you were an incident responder, you’d probably read this chart left to right. Lets say i have a Samsung S23 running presumably android 13 or 14, I’d first look at the samsung rows, choose the second one for the version, and then id have to determine if the device is in BFU or AFU mode, and see which options are available to me. In this instance, it doesn’t make a difference because I can get user data from either (because i can brute force the password on the lockscreen for this specific device). Otherwise, a BFU extraction might only pull out surface level information from the device because everything may not have been decrypted yet.

    I feel like I’m rambling but I hope it’s shedding some light, your point about the password is important but not everything. Companies like Cellebrite and Magnet pay a lot of money for zero day vulns that they can build exploits for into their software, meaning that if theres something critical (like a pin code bypass) then they could just use that and get all your data. But, there’s a lot of various data on cellphones, take Signal for example (and this is just an example, I don’t actually know): it’s possible that if signal is encrypting messages stored on the device, that even if an examiner pulled that database out, they might still not be able to do anything about it.

    My final point, there’s also a high degree of secrecy around these tools. Obviously Cellebrite and Magnet are incentivised to keep their exploits quiet so they continue working, otherwise Google or Apple could just issue a security patch and render them useless. Often, they’ll have different tools that are available to different organizations: a company may have a few cellebrite dongles for internal investigations and litigation support, the details of which are kept under NDA, but they’re still likely to be separate from what an organization like the FBI would have access to. This is why it’s often hard to find information on these tools, especially updated or recent information






  • No, having certain skintones doesn’t magically make you immune to skin cancer, wear your fucking sunscreen.

    Complete protection? Certainly not, but melanin does provide some protection from UV radiation. Still important to wear sunscreen because if a melanated individual where to get skin cancer it usually has a higher mortality rate because they’re often caught late.

    Epidemiological data strongly support the photoprotective role of melanin as there exists an inverse correlation between skin pigmentation and the incidence of sun-induced skin cancers (1) and subjects with White skin are approximately 70 times more likely to develop skin cancer than subjects with Black skin (67). The shielding effect of melanin, especially eumelanin, is achieved by its ability to serve as a physical barrier that scatters UVR, and as an absorbent filter that reduces the penetration of UV through the epidermis (68). The efficacy of melanin as a sunscreen was assumed to be about 1.5-2.0 sun protective factors (SPF);

  • It’s a program that uses an SDR to pick up the signals broadcasted by planes (ADS-B) containing their flight information. Then the data gets uploaded to an aggregator (FR24, Flight Aware, ADS-B Exchange) that gives a global view of all planes in the sky.

    You can use the aggregators for free without uploading, but you get some perks for being a contributor. I just do it because it’s cool and I use the platforms for getting info on flights I’m taking (you can tell if your flight is gonna be delayed if the plane is delayed elsewhere for example).
