  • What sense is licensing operating system on BSD license?

    Jump

  • Openbsd is definitely more secure than secureblue. There is only so much you can do to handle the massive monolithic architecture of the Linux kernel. Further down the stack, many parts of Linux, like sudo, dbus, or systemd are regularly hit by zero days. The SELinux domain architecture that Secureblue is interesting, but SELinux is extremely complex and difficult to get right, compared to the much more simpler pledge and unveil sandboxing that openbsd offers.

    In addition to that, there are further issues like the problematic way that user namespaces interact with browsers. (And user namespaces are frustrating in general, secureblue actually has a short article on their problems). For maximum security, you want to sandbox tabs from eachother using user namespaces (only works on chromium btw, firefox can't do this so it doesn't matter) — BUT, if you run your browser in a sanbox created by user namespaces, then you can't nest them, disallowing you from using that powerful tool to isolate tabs. So you are forced to make a choice: You can either sandbox the browser itself, in exchange for weakening the isolation between tabs, or you can strengthen the isolation between tabs, in exchange for weaking the sandbox around the browser itself. Giving the browser access to user namespaces is questionable though, because see above, user namespaces have led to a lot of vulnerabilities.

    OpenBSD's pledge + unveil (but only on chromium again), does not really make such tradeoffs. It can sandbox tabs from eachother, while also sandboxing the browser itself. In addition to that, pledge + unveil do not present a massive kernel attack surface that people have had to restrict for having too many 0days. And this is just one of the many, many examples, where OpenBSD presents a better security posture than Linux.

    Qubes is technically Xen, a different kernel than Linux. The Xen kernel virtualizes Linux distros, from which you can manage Qubes/Xen, or do normal Linux app stuff. But nothing stops you from using a BSD virtualized by Xen for management or usage. Qubes talks about why they use Xen here — but the short version is that they did not consider the Linux kernel's kvm secure enough for their usecase.

  • How to access home network (eg, VPN) without port forwarding?

  • Weird server requests

    Jump

  • What port was this sent to, and what webserver are you running (if it was sent to a webserver)?

    This reminds me of the string to strigger the really bad apache vulnerabilities that lead to being able to read from the whole filesystem (path traversal), or get a shell on your system (remote code execution). It's likelu that bots are spray and praying attempts across the internet. As long as you're up to date, you should be good.

  • EA is hiring a Senior Anti-Cheat Engineer to lead development of a native ARM64 driver for their Javelin kernel anti-cheat system and start laying groundwork for Linux/Proton support

    Jump

  • I've had similar experiences with this FPS game called krunker.io

    Krunker.io is a browser based game, and it had a pretty bad cheating problem, and since it was a browser based gamr, the devs could never implement an anticheat that worked for long.

    They implemented a deputization system, where certain respected members of the community would become "krunker police", and then you could call them from a lobby. They would then invisibly spectate, and record and ban cheaters. The system worked really well, actually. Cheaters were banned quickly, and the requirement collection of video evidence held those involved accountable.

    But krunker players had another interesting way of handling cheaters. You see, krunker has really bad netcode, bad enough that you would have to lead hitscan weapons a variable amount depending on how much ping you had. Krunker was also a movement shooter, where you could slidehop and go really, really fasy. The combination meant that you could dodge the shots of cheaters. As I got better, I just stopped calling krunker police, and started beating them. One of my fondest memories was this one lobby full of good players, and when a cheater joined we stomped them below all of us on the ranking, taunting them all the way down. At the end, they tried to sell their cheats and we all laughed. "Why would I buy these cheats? I'm better than them". Eventually they ragequit. Good times.

    But nooooo, nowadays modern game publishers need control over every part of the game. They demand control over the servers, refusing to let anybody host their own communities. They demand absolute control over the community, but refuse to actually moderate it and handle toxicity. And now, they're demanding control over the clients, forcing you to install rootkits on your computers so they can control those too.

  • What sense is licensing operating system on BSD license?

    Jump

  • FreeBSD, OpenBSD and NetBSD are behind Linux.

    Look, I dislike permissive licenses too, but you need a source to back this claim up.

    Right now, each BSD does something special, that Linux (distro's) can't trivially replace, even if the usecase is more niche. NetBSD Dev's make efforts to get it running on many devices as they can. OpenBSD (and it's subprojects) are highly secure, moreso than Linux. Who do you think makes our beloved OpenSSH? OpenSSH noted for having very few vulnerabilities over it's two decade long existence, and OpenBSD itself is similar, which is insane because there are products with multiple bad vulnerabilities every year (Linux being one of them...). This is due to a highly security minded architecture - one that Linux lacks.

    FreeBSD is like Linux before systemd. I like systemd, but systemd is really trying to be kubernetes on a single node. I like systemd because I like kubernetes, but I understand why someone wouldn't like it, and I question if "single node k8s" is the best architecture for a single server or personal desktop. The ports system results in freebsd packaging many server services that aren't packaged on Linux. Being able to manage those through the system package manager, and the conviniences that provides, is nice.

    Different, and not popular don't mean bad.

  • Adding "Log In With Mastodon" to Auth0 - Terence Eden’s Blog

    Jump

  • This reminds me of the way that forgejo lets you feed it an arbitrary openid url, so you can log in with any service you want, including your own server.

    Also, is this compatible with lemmy? The last time I tried fediverse (mastodon) login, it was with owncast, but it didn't work with lemmy.

  • How to Automate QEMU/KVM VM Deployments?

    Jump

  • Have you used ovirt? It's currently being maintained by Oracle after Red Hat gave it up.

    I've been meaning to try it, but the documentation is dense and hard to get through, and I unironically find the openstack install instructions more approachable in some ways...

  • How to Automate QEMU/KVM VM Deployments?

    Jump

  • My recommendation is to use an abstraction layer that runs qemu-kvm under the hood and automate that. Some people have mentioned libvirt, but Incus is another good option.

  • Twitch: "Hey, come back! This commercial break can't play while you're away."

    Jump

  • Owncast is the self hosted stream thing. It has some rudimentary federation capibilities, but nowhere near the ease discovery of twitch.

    I know some streamers that have an owncast, expired_popsicle uses debian Linux and has one. (It's tech/linux streamers because of course).

  • It's me again. My Kubernetes devolver has reached the astral plane.

    Jump

  • go run works by compiling the program to a temporary executable and then executing that.

    can you guarantee that runs everywhere

    It seems to depend on glibc versions, if that's what you are asking. You can force it to be more static by using a static musl python or via other tools. Of course, a binary for Linux only runs on Linux and the same for Windows and Mac. But yeah.

    Also it should be noted that go binaries that use C library dependencies are not truly standalone, often depending on glibc in similar ways. Of course, same as pyinstaller, you can use musl to make it more static.

  • It's me again. My Kubernetes devolver has reached the astral plane.

    Jump

  • You can create static binaries that bundle the python interpreter and dependencies.

    It's the onefile option in pyinstaller: https://pyinstaller.org/en/stable/usage.html#cmdoption-F

    You can also do it with C. Or Csharp. Or many other programming languages. It's not a feature unique to Go, it's just that Go can only create static binaries.

  • My thoughts shopping around for a wiki solution

    Jump

  • What about a static site generator? Plaintext, markdown, but renders to html with headings and whatnot. Version control is because it's in git.

    Read access control is difficult though. You could do some hacks like using encrypting files in the git repo (perhaps with SOPS), and then either using http basic auth to control access to specific pages or something like staticrypt. But these are not ideal solutions.

  • What headsets are linux gamers using?

    Jump
    1. Bluetooth probably won't be able to give you good quality audio and mic input at the same time. It doesn't have enough bandwidth over a single channel, last time I tried. Of course that was probably like 5 years ago and things might've changed, like a theoretical workaround I thought about is the headset simply having two bluetooth reveivers and connecting twice. But yeah.

    Edit: I suspect jgrffn's comment in the thread refutes the above. I might test later.

    1. Most of the proprietary wireless 2.4 ghz usb adapters I have tried have worked fine and better than bluetooth since they can do good audio and mic at low latencies. I have used logitech and corsair but my logitechs died on me (one I bought had the left side die and the other the right side :/) and the corsair earmuffs fell apart after I made the mistake of not being perfectly dry once. So I can't really recommend my most used headsets.

  • Looking for Complex Text Manipulation CLI tools

    Jump

  • This is technically yaml I think, a list (with one entry) of lists that contains mostly single items but also one other list. You should be able to parse this with a yaml parser like pythons built in one.

    Note that yaml is picky abiut the syntax though, so it wouldn't be able to handle deviations.

  • A sneaky demonstration of the dangers of curl bash

    Jump

  • I won't lie, I use curl | bash as well, but I do dislike it for two reasons:

    Firstly, it is much, much easier to compromise the website hosting than the binary itself, usually. Distributed binaries are usually signed by multiple keys from multiple servers, resulting in them being highly resistant to tampering. Reproducible builds (two users compiling a program get the same output) make it trivial to detect tampering as well.

    On the other hand, websites hosting infrastructure is generally nowhere near as secure. It's typically one or two VPS's, and there is no signature or verification that the content is "official". So even if I'm not tampering with the binary, I can still tamper with the bash script to add extra goodies to it.

    On the other hand (but not really relevant to what OP is talking about), just because I trust someone to give me a binary in a mature programming language they have experience writing in, doesn't mean I trust them to give me a script in a language known for footguns. A steam bug in their bash script once deleted a user's home directory. There have also been issues with AUR packages, which are basically bash scripts, breaking people's systems as well. When it comes to user/community created scripts, I mostly trust them to not be malicious, and I am more fearful of a bug or mistake screwing things up. But at the same time, I have little confidence in my ability to spot these bugs.

    Generally, I only make an exception for running bash installers if the program being installed is a "platform" that I can use to install more software. K3s (Kubernetes distro), or the Nix package manager are examples. If I can install something via Nix or Docker then it's going to be installed via there and not installed via curl | bash. Not every developer under the sun should be given the privilege of running a bash script on my system.

    As a sidenote, docker doesn't recommend their install script anymore. All the instructions have been removed from the website, and they recommend adding their own repo's instead. Personally, I prefer to get it from the distro's repositories, as usually that's the simplest and fastest way to install docker nowadays.

  • Yet another reason to hate on the worse DB in existence

    Jump

  • Unfortunately deleted means deleted. Data gone.

    My recommendation is to use it as a reverse proxy to expose services but ultimately host from another device.

    It's 1 gb of ram anyway (the free 24 gb of ram arm vps' are scarce and hard to get).

    Another tip is that they monitor cpu and ram and are more likely to delete it if is idling. There exist programs on github that do nothing but waste cpu in order to try to keep the oracle vps up.
