  • Keycloak or alternative?

    Jump

  • In addition to adding more worker instances, you can also increase the amount of threads each worker instance uses to vertically scale. It's about equivalent to adding a worker instance.

  • Authentik is definitely the best of all I've tried. It has the most features, supporting both ldap and oauth, and also has an official helm chart.

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

  • 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.

  • 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.

  • Selfhosted, multiplayer, browser based games

    Jump

  • oh I have tested this game somewhat, although I've never actually played it. It is very impressive.

  • 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.

  • 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.

  • k8s storage (CSI)

  • Openebs mayastor

    But you could fit ceph on that I think. As long as your network between nodes is fast enough.

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

    Jump

  • They like to randomly delete them. It happened to me and a friend.

  • Quick guide on using the Eduroam university internet on Linux

    Jump
    1. Use networkmanager. Other alternatives technically work but I have has seen many people struggle with alternatives, they are not as smooth.
    2. Follow the instructions for connecting on android devices. The options will be named the same.

  • Why is self-hosted voice chat so hard?

    Jump

  • It's easy. Mumble. Or the thing you used probably still works.

    But you see, people never actually seek a discord alternative. They want a discord alternative that includes all the features in one app that is also federated, AND end to end encrypted, and each one makes things vastly more technically challenging and resource intensive and then you want them together.

    A little secret: Matrix is much, much easier to host if you disable encryption and federation. Federation to many servers is the main performance killer, and "failed to decrypt message" will all disappear if you disable encryption.

  • Cheap or free periodical externals scans

    Jump

  • If your software updates between stable releases break, the root cause is the vendor, rather than auto updating. There exist many projects that manage to auto update without causing problems. For example, Debian doesn't even do features or bugfixes, but only updates apps with security patches for maximum compatibility.

    Crowdstrike auto updating also had issues on Linux, even before the big windows bsod incident.

    https://www.neowin.net/news/crowdstrike-broke-debian-and-rocky-linux-months-ago-but-no-one-noticed/

    It's not the fault of the auto update process, but instead the lack of QA at crowdstrike. And it's the responsibility of the system administrators to vet their software vendors and ensure the models in use don't cause issues like this. Thousands of orgs were happily using Debian/Rocky/RHEL with autoupdates, because those distros have a model of minimal feature/bugfixes and only security patches, ensuring no fuss security auto updates for around a decade for each stable release that had already had it's software extensively tested. Stories of those breaking are few and far between.

    I would rather pay attention to the success stories, than the failures. Because in a world without automatic security updates, millions of lazy organizations would be running vulnerable software unknowingly. This already happens, because not all software auto updates. But some is better than none and for all software to be vulnerable by default until a human manually touches it to update it is simply a nightmare to me.

  • Cheap or free periodical externals scans

    Jump

  • Second comment, but also investigate Wazuh. It can audit systems and report vulnerabilities. It's not an external scanner, but I have found it to be more effective and less annoying than greenbone/openvas.

  • Cheap or free periodical externals scans

    Jump

  • Instead of trying to automatically scan your environment, it's probably better to figure out how to automatically update applications first. CVE's eventually get patched.
