Is it possible to enable automatic updates for Flatpak programs in Discover? in c/[email protected]
[–] Kalcifer 1 points 1 year ago

There is a selection for automatic updates under Settings > Software Update, but I swear it does nothing on my distro.

This appears to be a known bug.

Is this community still alive? If yes I've got a Rust-question. in c/[email protected]

Yes, this community is stil alive.

I don't really have an exact answer to your question, as I don't write Rust, and I've never used a Raspberry Pi for electronics, but I have some educated input:

There is a max7219-crate that used. But i am unsure about how to prepare the pins want to use.

Presumably, the crate just exposes pre-defined config objects that you call in your code.

Can Use any of the pins?

From what I recall, no, you can't use any of the pins on the Raspberry Pi as generic IO (all this information that you are looking for is in the datasheets of the devices that you are using) -- some pins are dedicated for power, etc.

Do have to set them to push-pull-output?

Generally speaking, yes, if you want to use a generic I/O as an output, then you must configure it as such.

I'm not sure that there is much for actual server side support for cross posting just yet, but there is a way, at least on the web UI: if you click the two overlapping squares under you post title, it'll open a new post with a link to the previous post and its content quoted underneath. It feels more like a work around for cross posting, but it does work.

I was referring to Rule 3 of the community:

  1. Not regarding using or support for Lemmy

TL;DR: There is no singular answer to your question, imo. Essentially just run the instance transparently, reliably, and actively, and it will be attractive to people.

I'm not sure that there is one "best way" to grow an instance. An instance is essentially the fundamental governing framework for how the users interract with each other. You structure the rules around how you believe the users on your instance should interact, and those who agree with those rules will be drawn to them. Ideally, for sustainable growth in an instance, you also need reliable server infrastructure -- the instance should be responsive, and have a reliable uptime. An instance's admins must also actively moderate content. An instance with inactive moderators is not sustainable, and will quickly delve into hosting unwanted content on the instance which is undesirable for users.

This post possibly violates Rule 3 of [email protected].

What is the little Fediverse icon/logo for that is beside a user's name in a comment? in c/[email protected]

Thank you for the apology 😊 I can understand how my post could've been construed as being lazy.

[–] Kalcifer 6 points 1 year ago* (last edited 1 year ago) (4 children)

??? Why don’t you tap it and see.

I did try that. Nothing appeared to happen, or change on my end; however, I now realize what the issue was. The first thought that I had, when I first noticed that Icon, was actually the exact same as that which you said; it just never occured to me that I could be on the same instance as the comments in question. So, when I tried clicking that icon, I was clicking it on a post that was from Lemmy.world -- the same instance that I am on. As such, I noticed no change in the displayed content -- the page would appear to load, but nothing would actually change. This is, of course, to be expected -- I just didn't put 2 and 2 together. I apologize if my inquiry seemed lazy, or thoughtless.

As an aside, In my defence, the UI also doesn't necessarily tell you what the icon does. If you hover your mouse over it, you will see the following:

Imo "link" isn't exactly descriptive, as to the button's purpose.

Can a user that is located on a different instance from where a community is hosted be a moderator of that community? in c/[email protected]

likely will cause issues at some point

What sort of issues?

Does anyone know how to verify a Mastodon profile using a WordPress site? in c/mastodon

Are you referring to the verification checkmark? If so, then follow this.

Is it possible to enable automatic updates for Flatpak programs in Discover? (self.kde)
submitted 1 year ago* (last edited 1 year ago) by Kalcifer to c/[email protected]

I can't seem to find any setting to enable automatic updates in Discover. Currently, I get a ping for available updates, nearly every day, and I then have to manually click "Update". I would much prefer for Flatpaks to automatically update themselves in the same way that Gnome Software does it.

I understand the negative sentiment that many have towards automatic updates, but, for Flatpaks, it's a risk that I am completely willing to take.

Update #1:

There appears to be a setting for toggling automatic updates in System Settings>Software Update>Update software>Automatically; however, it appears to be a known bug that this is currently broken with flatpak.

Is there a standard for recurring cryptocurrency payments? (self.cryptocurrency)
submitted 1 year ago by Kalcifer to c/cryptocurrency

From my experience, it seems that any service that offers cryptocurrency payments seems to always set them up as a one time purchase that you manually must renew periodically. Is there any standard that exists, or is in the works that supports recurring payments to a service directly from a wallet?

How do you back up Nextcloud, installed as a snap, using the Backup app? (self.selfhosted)
submitted 1 year ago by Kalcifer to c/selfhosted
2 comments fedilink
 

I have Nextcloud installed as a snap. I would like to back it up to a folder on a separate drive within the server. Nextcloud appears to have an official backup app, which I have installed on the Nextcloud instance.

Is it possible to connect a folder on a separate drive to Nextcloud running as a snap? What permissions should such a folder have?

If I were to set up a self hosted Gitea instance right now, how would I be impacted down the line when they implement federation? (self.gitea)
 

cross-posted from: https://lemmy.world/post/2121242

Would I have to do anything on my end, or would everything be set up automatically when the update is pushed?

How do you all go about backing up your data, on Linux? (self.linux)

I'm trying to find a good method of making periodic, incremental backups. I assume that the most minimal approach would be to have a Cronjob run rsync periodically, but I'm curious what other solutions may exist.

I'm interested in both command-line, and GUI solutions.

Is Matrix's encryption "quantum-safe"? (self.privacy)
 

cross-posted from: https://lemmy.world/post/2112774

There's a growing concern that "bad-actors" are amassing troves of encrypted data, and storing it away for possible future decryption using quantum computers. Many services have put in efforts to make certain that their encryption algorithms are "quantum-safe", so as to protect against such attacks. Has Matrix done the same?

How does using Matrix compare with using Signal, privacy-wise? (self.matrix)
 

cross-posted from: https://lemmy.world/post/2077535

I'm not sure if it is entirely accurate to compare them in this way, as "Matrix" refers to simply the protocol, whereas "Signal" could refer to the applications, server, and protocol. That being said, is there any fundamental difference in how the Matrix ecosystem of federated servers, and independently developed applications compares to that of Signal that would make it less secure, overall, to use?

The most obvious security vulnerability that I can think of is that the person you are communicating with (or, conceivably, oneself, as well) is using an insecure/compromised application that may be leaking information. I would assume that the underlying encryption of the data is rather trustworthy, and the added censorship resistance of federating the servers is a big plus. However, I do wonder if there are any issues with extra metadata generation, or usage tracking that could be seen as an opsec vulnerability for an individual. Signal, somewhat famously, when subpoenaed to hand over data, can only hand over the date that the account was created, and the last time it was used. What would happen if the authorities go after a Matrix user? What information about that user would they be able to gather?
