Found in the wild: The world’s first unkillable UEFI bootkit for Linux
  • Don't know, been rolling with Gentoo for some time now.

    I wouldn't trust "out of the box" support anyway as that would imply trusting microsoft keys.

  • Suggest me an upgrade for a server and streaming
  • I've not read all of it, but if you're referring to the stuff at the beginning - none of those limitations apply to 5700xt.

    If you mean something else - then, naturally, I would ask if it actually affects your media in the first place. It might, but I wouldn't expect that.

  • Which podcast player do you use for android?
  • Podcini, got it on f-droid. Does what it says on the tin!

  • Found in the wild: The world’s first unkillable UEFI bootkit for Linux
  • Do you know how that works? Is it something like Ubuntu where Canonical uses some sort of chain from Microsoft or do you have to embed the cert they provide into UEFI yourself?

  • Yes, failing to safeguard keys is fatal, but that applies to everything. But if fs you're storing keys on is behind luks and they're readable by root only - you're as safe enough. There're also LSMs like selinux that can increase the complexity of attack.

    I don't know about nitrokey specifically, but TPM is an option (not good enough, imo) and a simple luks encrypted usb. You could get some convenience by storing the key to unlock it somewhere on the encrypted root.

    In general - you cannot stop a targeted attack no matter what, but staying safe from all the automated ones is doable.

  • Nintendo targets Reddit pirates in piracy crackdown
  • No it can't. You're still thinking about github and its built in "forking" mechanism.

  • Nintendo targets Reddit pirates in piracy crackdown
  • There is no federated guthub because git itself is. Just clone the repo - you're part of the network already!

  • Suggest me an upgrade for a server and streaming
  • in case you want to tell me what I have is fine and I don't need an upgrade

    What you have is fine and you don't need an upgrade 😁

    But we're not looking for fine, are we? :)

    I would keep the gpu and get as many cpu cores and ram as my budget allows. Once you cross into "stupid amount of RAM" territory you can start utilising tmpfs for transient things such as jellyfin transcode directory to:

    • preserve those precious ssd writes (not really relevant anymore)
    • make it more efficient (feels-good kind of relevant)
    • running a filesystem in ram is really cool (most relevant, naturally :D)
  • Found in the wild: The world’s first unkillable UEFI bootkit for Linux
  • It is a system one has to understand fully, i.e. not like ssh, where you can understand connecting to a remote host without bothering about key pairs, x11 forwading, etc.

    I was lucky enough to have figured out Gentoo enough where plugging in secure boot was just extending my own system update script. Admittedly, I don't know how much other distros fight back.

  • What movies do you recommend that actually benefit from 4K rendering?
  • In general - things that are colourful and/or have special effects.

    Blue Planet, Top Gun Maverick, Fast and Furious saga (not the first few, 4k made no difference there) come to mind first atm.

    Things that have acting and script itself as the main selling point generally are perfectly fine in 1080p. The Office and Slow Horses would be a good example of that, I suppose.

    Personally, I get everything I want my son to watch in the highest quality I can - Shawshank Redemptiom and Shutter Island are the latest additions to my library that, I think, would absolutely fine in 1080p, but... 4K HDR it is :D

  • Found in the wild: The world’s first unkillable UEFI bootkit for Linux
  • Yea, I guess that initial total lack of understanding and big headlines has left a long-lasting scar. Admittedly, secure boot could be used to lock a machine down if the ability to turn it off and/or manage the keys yourself was removed.

    We'll get there, eventually :)

  • Found in the wild: The world’s first unkillable UEFI bootkit for Linux
  • The Bootkitty sample ESET found is unable to override a defense, known as UEFI Secure Boot, that uses cryptographic signatures to ensure that each piece of software loaded during startup is trusted by a computer's manufacturer.

    AKA not that big of a deal, yet. An article from another post about this also mentions GRUB explicitly as a requirement as well as PoC using self signed keys, which renders it sort of impossible to abuse.

    UKI + your own keys + secure boot is still not broken.

  • Can a disk image with multiple partitions be shrunk in a reasonably easy way?
  • This! I've done it many a time following 3.7 Full system backup. For some reason can't get table of contents to load on mobile and get a proper anchor link.

  • If you were a rich man... What would you do?
    • Get a house with a garden (backyard)
    • Start my own laptop/desktop line
    • Obtain and maintain a naturally aspirated manual V12 Aston Martin
  • Russia-linked hackers exploited Firefox and Windows bugs in 'widespread' hacking campaign
  • I wonder if this was the reason for f-droid suggesting removing firefox variants.

  • I can't imagine being paid to act like I enjoy working in the office
  • Not OP you've responded to, but the post really sets the tone for that.

    Maintenance Complete

    Everything went through smoothly, but please do report if you notice anything.

    Lemmy Cafe will be having its database upgraded.

    Reasons

    • PostgreSQL 17 has been released and the changelog is promising a lot of IO improvements. Lemmy sure could use it given the constant stream of small events flowing in.

    Plan

    • Point nginx to the maintenance page
    • Shut down PostgreSQL 16
    • Run the upgrade tool
    • Start up PostgreSQL 17
    • Point nginx to lemmy

    Expected downtime

    About an hour, if things go well. More if not so.

    Will try to keep the maintenance page updated.

    Admittedly, I have a fairly serious bias against Microsoft, so it's unlikely they'll every say much I can trust; but I am genuinely surprised their marketing department didn't even bother coming up with another name to try selling this atrocity.

    Lemmy.Cafe Housekeeping

    Due to the recent @Soup's post I have decided to do some housekeeping. I've been getting frustrated at lemmy's performance at times as well and this simply was a wake up call, if you will.

    I am sorry about no advance downtime annoucement - Sunday is the only day I can really put any meaningful amount of time into lemmy.

    ___ Things done today:

    • Upgraded database VM 1 core 2GB -> 2 cores 4GB. Double the compute, double the memory.
    • Adjusted database config to account for increased resources
    • Adjusted hugepages config to account for increased database's requests
    • Updated both lemmy and database VMs
    • Rebooted the lot

    ___

    Thank you for your patience. I will also use this moment of focus to write up a financial report in a separate post.

    Also, thank you, @Soup!

    ___ EDIT: I've also marked all instances known to lemmy.cafe as active. What this means is that lemmy.cafe will now keep retrying to federate to everything very aggressively. This is a compute-intensive process and will also impact performance for a few hours, until exponential backoff kicks in. I've done it to revive any falsely-marked-as-dead instances; there's no fix for it on lemmy itself.

    Yea, it feels an awful lot like VC funded businesses - they lure you in with low pricing, bankrupt and buy out the competition and then hold you by the balls.
