    KDE for best fully integrated, out of box, modern DE.

    XFCE + Compiz if you’re running on lower end hardware (uses less ram and utilizes gpu better). Also if you want even more customization than KDE with the drawback of limited SVG support (and still on X11 if that matters for you)

    GNOME if you hate yourself and want to use a knockoff of ChromeOS or Mac.

    Cinnamon and MATE if you want to see when GNOME used to be good.

    LXQt is the XFCE equivalent of KDE, but is now on wayland with GPU accel, so it can fit the same area as XFCE+Compiz.

    Wayfire (compositor) basically Compiz for Wayland if you want all the fancy effects on anything that uses wayland.


  • ITT: Braindeads defending government censorship of the internet as if Zuckerberg won’t immediately replace the void with his own platform or by buying out TikTok in a bid.

    Banning one platform would not magically get rid of short attention span and brainrot you fools. Every social media company already copied or utilizes the same techniques as TikTok, which is already a massive platform because they don’t spam ban or regulate content as hard as Facebook and YouTube do.

    It is insulting that a Chinese run social media platform provides more freedom of speech online than its US competitors.

    They’re banning it to remove competition, congress does not care about its effects on privacy or health, otherwise they’d have done something about Faceebook, Insta, Twiiter, and YouTube decades ago. They pulled their usual committee shenanigans to pretend to care by calling in CEOs to testify, and then promptly accepting a shitload of lobbying money.



  • The TPM is not a dedicated cryptographic processor, it’s an external keystore with a few select functions. You’re thinking of an HSM which is used almost exclusively in servers that have to handle thousands of secrets per second.

    CPUs have had dedicated AES hardware for decades which is why LUKS and Bitlocler use it by default.

    The TPM just allows certain keys and secrets to be generated and stored physically separate from the CPU as a security measure.

    Bitlocker and LUKS will store a master key in the TPM so that you don’t have to enter a password every time you boot. They retrieve it from the TPM and then use it to unlock the actual encryption key which is done entirely in the CPU. If the TPM detects foul play such as secure boot alteration, it will refuse to give the key or clear itself.

    Using the TPM for constant encryption like at rest disk encryption would be way too slow.

    It’s so so small that most modern TPMs have been integrated into the CPU or even simulated via the motherboard firmware (fTPM and PTT).


  • I still fail to see how windows 11 was anything but a collusion scam to sell new hardware.

    None of the changes including TPM requirements required a new iteration. Nothing about the underlying NT dropped any of the old and antiquated BS despite Microsoft hiring some morons to advertise the fact on reddit to all the insiders asking questions.

    They even let the media pick up a fake report that Windows 11 was related to the Core OS and a brand new kernel was in the works.

    If Microsoft wanted a marketing strategy, they could have properly started naming feature updates and adverising them similar to Apple.

    8, 10, and 11 have also been a pain on enterprise because Microsoft axed their QA team. I seriously hope any new firms start considering linux desktop as a valid option. All they really need is a vendor to offer a solid distro along with an agreement to rapidly create/deploy any software solution so they don’t get scared looking at the cheap entry windows stuff.



  • The Fedora doc on this is a bit old but it’s still mostly the same:

    Secure boot activates a lock-down mode in the Linux kernel which disables various features kernel functionality:

    • Loading kernel modules that are not signed by a trusted key.
    • Using kexec to load an unsigned kernel image.
    • Hibernation and resume from hibernation.
    • User-space access to physical memory and I/O ports.
    • Module parameters that allow setting memory and I/O port addresses.
    • Writing to MSRs through /dev/cpu/*/msr.
    • Use of custom ACPI methods and tables.

    The implementation of secure boot is still questionable to this day, but it is understandable that it doesn’t always play nice with Linux. I do believe you can use hibernate now as long as you have an encrypted swap (LUKS).

    I can definitely see the pain if you happen to be a kernel dev or use linux on any SBC with IO ports you want to mess with in userspace and not make en entire overkill kernel module for.


  • The main thing they are trying to do is make it more difficult to find this stuff via google, which tbh is still easy without reddit.

    But even Switch homebrew has been a pain. Most of it is one off software made years ago because no sane dev wanted to actually keep up with all the firmware releases and limited control of CFW. Github/Gitlab repos keep getting banned left and right for tools not even related to piracy.

    3DS has full fledged apps with teams behind everything and HShop which makes it very easy for everyone. Switch still doesn’t have a definitive method of handling NSP/XCIs, and all the auto download internet repos are invite only to hide from Nintendo.

    I’m really hoping someone finds some serious hardware bypass in their next console after what they did to the emulation scene. They really deserve to go through the insane R4 piracy age all over again for nuking everything online.


  • I thought it was already fairly well established that symmetric encryption is not something that a quantum computer could potentially crack, only asymmetric encryption is theoretically possible due to its use of a prime order field.

    Shor’s algorithm is a quantum algorithm for finding the prime factors of an integer. It was developed in 1994 by the American mathematician Peter Shor.[1][2] It is one of the few known quantum algorithms with compelling potential applications and strong evidence of superpolynomial speedup compared to best known classical (non-quantum) algorithms

    a quantum computer with a sufficient number of qubits could operate without succumbing to quantum noise and other quantum-decoherence phenomena, then Shor’s algorithm could be used to break public-key cryptography schemes, such as

    • The RSA scheme
    • The Finite Field Diffie-Hellman key exchange
    • The Elliptic Curve Diffie-Hellman key exchange

    Moreover:

    The largest number reliably factored by Shor’s algorithm is 21 which was factored in 2012 (ie faster than a regular computer, the much higher records like 48 bit utilized pre and post processing and was faster on a regular computer).

    Even if we go with the assumption that the military is 10 years ahead in technology and can factor 221 with Shor’s, that’s still nowhere near enough to break RSA. Much more efficient to attack all the systemic flaws in RSA, hence why 1024 is no longer considered secure, 2048 is assumed to be breakable by any 3 letter agency, 4096 is assumed to be safe (for now), but mostly the latest and greatest is elliptical ECDSA/Ed25519 (of which NIST has been accused of rigging ECDSA for easier cracking lol).


  • Bruh this comments section is making the wrong conclusions

    Clamshell design was and always will be the superior space format. There’s a reason why the DS and 3DS had so much homebrew, it was practically the successor to PDAs.

    Android foldables have barely scratched the surface in split screen and back screen utility, but the half size alone makes it very nice to carry.

    The real issue here is that yet another small groundbreaking OEM died because Android device development is an oligopoly. Google, Samsung, Motorola, and Oppo simply took the technology the moment it was revealed and immediately made competitor devices, regardless of initial quality, to get investors excited.

    No one was gonna invest in some small Chinese OEM if the big ones were gonna do the same thing and guarantee sales + existence.

    This exactly why Android feature development has stalled so hard. Everyone sits around twiddling their thumbs for several generations worth of phones until another startup comes up with a new feature they can implement for cash grab. It’s so bad we literally lost features like NFC bumping just to match what everyone else is doing.

    If some startup made a phone with the camera shifted an inch to the center, I can guarantee you the next pixel or galaxy will have it for literally no practical reason other than to prevent competition.








  • XFCE + Compiz

    The unholy combination of accelerated 3D graphics and performance, all without the stupid drawbacks of wayland.

    Runs much lighter than KDE even with all the 3D cube and windows stuff enabled.

    Extremely customizable as well. XFCE already does a great job of UI/UX, it just lacks a compositor to add flare (xfwm4 has no animations, only some blur effects).



  • This is why lots of software has started adopting SSPL license which doesn’t actually fix the problem and isn’t a FOSS license.

    I still think a new license scheme should be considered though. Giants like AWS and Google have been profiteering off of FOSS for way too long now.

    AGPL has been deemed generally successful in this regard because it has been upheld in court cases and forced companies to comply, which it seems to work pretty great for SaaS.

    The problem is these giants will usually just choose a more permissive alternative anyway. Both MongoDB and Redis have forks that they can use, and GPL itself is permissive enough for private forking being legal.
