Okay. This sounds very strange, but I had a similar issue with the nintendo switch pro controller and binding of isaac. I played around with antimicrox, but the real solution I found was to launch steam and leave it running. Then, my pro controller would magically work.

I didn’t have to launch the game via steam either, which is what made it even stranger to me.

Databases are special. They ofte implement their own optimizations, faster than more general system optimizations.

For examole: https://www.postgresql.org/docs/current/wal-intro.html

Because WAL restores database file contents after a crash, journaled file systems are not necessary for reliable storage of the data files or WAL files. In fact, journaling overhead can reduce performance, especially if journaling causes file system data to be flushed to disk. Fortunately, data flushing during journaling can often be disabled with a file system mount option, e.g., data=writeback on a Linux ext3 file system. Journaled file systems do improve boot speed after a crash.

I didn’t see much in the docs about swap, but I wouldn’t be suprised if postgres also had memory optimizations, like it included it’s own form of in memory compression.

Your best bet is probably to ask someone who is familiar with the internals of postgres.

The cloud, and any form of managed database, inverts this. User accounts are extremely easy, as they are automatically provisioned with secrets you can easily rotate, along with the database itself. There is less of a worry about user rights as well, as you can dedicate one “instance” of a database to certain types of data, instead of having more than one database within one instance.

And then, traffic is commonly going to be routed through untrusted networks, hence the desire for encryption in transit.

There are a few apps that I think fit this use case really well.

Languagetool is a spelling and grammer checker that has a server client model. Libreoffice now has built in languagetool integration, where it can acess a server of your choosing. I make it access the server I run locally, since archlinux packages languagetool.

Another is stirling-pdf. This is a really good pdf manipulation program that people like, that comes as a server with a web interface.

I use this for kubernetes secrets with sops. It works great.

I think I have also seen socket access in Nginx Proxy Manager in some example now. I don’t really know the advantages other than that you are able to use the container names for your proxy hosts instead of IP and port

I don’t think you need socket access for this? This is what I did: https://stackoverflow.com/questions/31149501/how-to-reach-docker-containers-by-name-instead-of-ip-address#35691865

I’ve seen three cases where the docker socket gets exposed to the container (perhaps there are more but I haven’t seen any?):

1. Watchtower, which does auto updates and/or notifies people

2. Nextcloud AIO, which uses a management container that controls the docker socket to deploy the rest of the stuff nextcloud wants.

3. Traefik, which reads the docker socket to automatically reverse proxy services.

Nextcloud does the AIO, because Nextcloud is a complex service, but it grows to be very complex if you want more features or performance. The AIO handles deploying all the tertiary services for you, but something like this is how you would do it yourself: https://github.com/pimylifeup/compose/blob/main/nextcloud/signed/compose.yaml . Also, that example docker compose does not include other services, like collabara office, which is the google docs/sheets/slides alternative, a web based office.

Compare this to the kubernetes deployment, which yes, may look intimidating at first. But actually, many of the complexities that the docker deploy of nextcloud has are automated away. Enabling the Collabara office is just collabara.enabled: true in the configuration of it. Tertiary services like Redis or the database, are included in the Kubernetes package as well. Instead of configuring the containers itself, it lets you configure the database parameters via yaml, and other nice things.

For case 3, Kubernetes has a feature called an “Ingress”, which is essentially a standardized configuration for a reverse proxy that you can either separate out, or one is provided as part of the packages. For example, the nextcloud kubernetes package I linked above, has a way to handle ingresses in the config.

Kubernetes handles these things pretty well, and it’s part of why I switched. I do auto upgrade, but I only auto upgrade my services, within the supported stable release, which is compatible for auto upgrades and won’t break anything. This enables me to get automatic security updates for a period of time, before having to do a manual and potentially breaking upgrade.

TLDR: You are asking questions that Kubernetes has answers to.

Try the yaml language server by red hat, it comes with a docker compose validator.

But in general, off the top of my head, dashes = list. No dashes is a dictionary.

So this is a list:

thing:
    - 1
    - 2

And this is a dictionary:

dict:
    key1: value1
    key2: value2

And then when they can be combined into a list of dictionaries.

listofdicts:
    - key1dict1: value1dict1
    - key1dict2: value1dict2
      key2dict2: value2dict2

And then abother thing to note is that yaml wilL convert things into a string. So if you have ports 8080:80, this will be converted into a string, which is a clue that this is a string in a list, rather than a dictionary.

The amazon appstore had this crazy setup where you could get microtransactions in certain games without spending any real money. I must have spent over $1000 on jetpack joyride. I unlocked everything.

I’ll say it again and again. The problem is neither Linus, nor Kent, but the lack of resources for independent developers to do the kind of testing that is expected of the big corporations.

Like, one of the issues that Linus yelled at Kent about was that bcachefs would fail on big endian machines. You could spend your limited time and energy setting up an emulator of the powerPC architecture, or you could buy it at pretty absurd prices — I checked ebay, and it was $2000 for 8 GB of ram…

But the big corpos are different. They have these massive CI/CD systems, which automatically build and test Linux on every architecture under the sun. Then they have an extra, internal review process for these patches. And then they push.

But Linux isn’t like that for independent developers. What they do, is just compile the software on their own machine, boot into the kernel, and if it works it works. This is how some of the Asahi developers would do it, where they would just boot into their new kernel on their macs, and it’s how I’m assuming Overstreet is doing it. Maybe there is some minimal testing involved.

So Overstreet gets confused when he’s yelled at for not having tested on big endian architectures, because where is he supposed to get a big endian machine that he can afford that can actually compile the linux kernel in less than 10 years? And even if you do buy or emulate a big endian CPU, then you’ll just get hit with “yeah your patch has issues on machines with 2 terabytes or more of ram” and yeah.

One option is to drop standards. The Asahi developers were allowed to just merge code without being subjected to the scrutiny that Overstreet has been subjected to. This was in part due to having stuff in rust, and under the rust subsystem — they had a lot more control over the parts of Linux they could merge too. The other was being specific to macbooks. No point testing the mac book-specific patches on non-mac CPU’s.

But a better option, is to make the testing resources that these corporations use, available to everybody. I think the Linux foundation should spin up a CI/CD service, so people like Kent Overstreet can test their patches on architectures and setups they don’t have at home, and get it reviewed before it is dumped to the mailing list — exactly like what happens at the corporations who contribute to the Linux kernel.

Signal’s reproducible builds are broken: https://github.com/signalapp/Signal-Android/issues/13565

There is uksmd for ram dedupe.

No, the duckstation dev obtained the consent of contributors and/or rewrote all GPL code.

https://www.gamingonlinux.com/2024/09/playstation-1-emulator-duckstation-changes-license-for-no-commercial-use-and-no-derivatives/

I have the approval of prior contributors, and if I did somehow miss you, then please advise me so I can rewrite that code. I didn’t spend several weekends rewriting various parts for no reason. I do not have, nor want a CLA, because I do not agree with taking away contributor’s copyright.

No, because they don’t deviate enough from arch to avoid issues with breakages on updates. Just recently on lemmy someone was wondering why all their vlc plugins were uninstalled. Easy fix for someone who knows how to use pacman, but that and similar incidents make cachyos not really a “just works” system.

Many helm charts, like authentik or forgejo integrate bitnami helmcharts for their databases. So that’s why this is concerning to me,

But, I was planning to switch to operators like cloudnativepostgres for my databases instead and disable the builtin bitnami images. When using the builtin bitnami images, automatic migration between major releases is not supported, you have to do it yourself manually and that dissapointed me.

Does that happen often? I had, apparently incorrectly, assumed those things were more or less fire and forget.

Bootloaders are also software affected by vulnerabilities (CVE’s). But this comment did make me curious. Do the CVE’s that affect grub, would a person of threat model/usecase 1 in my comment above care about them?

Many of them do indeed seem to non issues. From the list here.

Grub CVE’s requiring the config file to be malicious, like this one are pretty much non issues. The config file is encrypted, in my setup at least (but again, not the default. Also idk if the config file is signed/verified).

I think this one is somewhat concerning. USB devices plugged in could corrupt grub.

Someone could possibly do something similar with hard drives, replacing the one in the system. The big theoretical vulnerability I am worried about is someone crafting a partition in such a way that it does RCE through Grub. Or maybe’s it’s already happened, my research isn’t that deep. But with such a vulnerability, someone could shrink the EFI partition and then put another partition there, that grub reads, and then the code execution exploit happens.

But honestly, if someone could replace/modify hard drives, or add/remove USB devices, what if they just replace your entire system motherboard with a malicious one? This is very difficult to defend against, but you could check for it happening by having your motherboard be password protected, and you always log into your motherboard whenever you boot to make sure the password is the same. (Although perhaps someone could copy over the hashes (at least I am assuming the passwords are hashed) from one motherboard to another).

But if something like that is in your threat model, it’s important to note that ethernet, and many other firmware is proprietary (meaning you cannot audit or modify the code), and also has what’s called “DMA” — direct memory access. It can read and write to the Linux kernel with permissions higher than root. So if I have access to your device, I could replace your wifi card with a malicious one that modifies stuff after you boot or does any other things.

What you are supposed to do is prevent tampering in the first place, or for a much cheaper cost, have “tamper evident protection”, things that inform you if the system was tampered with. Stickers over the screws are an easy and cheap example…

But DefCon has a village dedicated to breaking tamper evident protection. Lol.

I think if your adversary is a nationstate, secure boot usecase 1 is simply broken and doesn’t work. It’s too easy to replace any of the physical components with malicious one’s for them, because there is no verification of those. I think Secure Boot usecase 1 is for protecting against corporate espionage in mid to high tier corpos. Corporations also tend to give people devices, and they can ensure that those devices have tamper evidence/tamper resistance on top of secure boot. Of course I think a nationstate can get through them, but I don’t think it’s included in the threat model.

Nationstates can easily break the system of secure boot, and probably have methods in addition to or separate from secure boot for protecting themselves.

Wait what, that just seems like home directory encryption with extra steps 🤦 I guess I’ll go back to Veracrypt then.

Performance on LUKS might be better since LUKS is a first class citizen. But maybe performance with veracrypt is better since only the home directory is encrypted. I tried duckduckgo but the top results were AI slop with no benchmarks so I’m not gonna bother doing further research.

I’m on my phone rn and can’t write a longer post. This comment is to remind me to write an essay later. I’ve been using authentik heavily for my cybersecurity club and have a LOT of thoughts about it.

The tldr about authentik’s risk of enshittification is that authentik follows a pattern I call “supportware”. It’s when extremely (intentionally/accidentally) complex software (intentionally/accidentally) lacks edge cases in their docs,because you are supposed to pay for support.

I think this is a sustainable business model, and I think keycloak has some similar patterns (and other Red Hat software).

The tldr about authentik itself is that it has a lot of features, but not all of them are relevant to your usecase, or worth the complexity. I picked up authentik for invites (which afaik are rare, also official docs about setting up invites were wrong, see supportware), but invites may not something you care about.

Anyway. Longer essay/rant later. Despite my problems, I still think authentik is the best for my usecase (cybersecurity club), and other options I’ve looked at like zitadel (seems to be more developer focused),or ldap + sso service (no invites afaik) are less than the best option.

Sidenote: Microsoft entra is offers similar features to what I want from authentik, but I wanted to self host everything.
