What's a good daily task app that doesn't require an account/Internet connection
  • I recommend downloading it from f-droid if you want full functionality (like self-hosted sync) for free -- the one in the play store is monetized (however I do recommend donating to the dev if you don't want to pay the subscription fee).

  • The user numbers in Lemmy communities don't add up
  • That's because, currently, the community stats that you see in the sidebar are only from your instance -- community stats are currently not federated. Afaik, federated community stats are going to be implemented in 0.19.

  • What should be used for anonymous usernames?

    More often than not, the best way to hide is to simply blend in with the crowds -- this also encompasses one's choice for a username. It is relatively simple to make a single throwaway account -- just come up with a username, and off you go -- however, if one makes throwaway accounts often, the task of thinking of a unique, and non-identifiable username can become a challenge. I would argue that poeple would often resort to using a pattern employing small changes for all subsequent usernames. Such patterns can be identified to a specific user if all users have their own unique patterns.

    How can one reliably generate many unique-but-normal, and non-pattern-identifiable usernames?

    Is it correct to use the present participle to describe what something does rather than only describing/modifying its current state?

    For example: > It is a thing that works producing stuff.

    This feels wrong to me, but I can't quite put my finger on what exactly is wrong about it. It seems like it's trying to be a participle phrase, but it's not necessarily modifying the current state of "it", and is, instead, describing what "it" is.

    If it is, indeed, a participle phrase, then it should be able to be written as > Producing stuff, it is a thing that works.

    But, to me, this doesn't seem correct either, so it leads me to believe that the very structure of the sentence is incorrect.

    At what size of transistor does semiconductor manufacturing become practical for independent manufacture?

    Currently, only one company in the world -- ASML -- has the technological capability necessary for the creation of photolithography machines which are sufficient for the production of modern semiconductor devices. What I'm wondering is at what point does semiconductor manufacturing become practical, or even feesible for small organizations, or independents? One must be able to surpass the cost of the machines, and the resources necessary to manufacture them. I presume that a company like ASML is also extremely picky -- willfully, or by regulation, or otherwise -- about who they lend their technology to.

    Deepfake Porn Is Out of Control
  • After some testing, It might be that the parent commenter just deleted their comment which nuked all the child comments. I can't rememeber if this is what Reddit does. I think it just sais "Deleted by creator", but keeps the children. Could certainly be wrong, though.

  • Deepfake Porn Is Out of Control
  • Yup it appears that our entire comment chain got nuked. So it is now confirmed that if you delete the parent, then all children get removed as well.


    For any reading this message, the context is that we tested it by me replying to OP's previous comment, then OP responding to me, then I deleted my comment to see if their comment also got deleted.

  • Why does this community, which is privacy oriented, use Discord rather than Matrix?

    On the side bar it lists the following: > - [Matrix/Element]Dead > - Discord

    "Discord" is an active link, but the Matrix link is completely inactive. Not only is it inactive (which could have be excused as a broken link), but it is also manually labeled as "Dead", as if there is no intention of making it work. How can a community that is focused on privacy willingly favor a service that is privacy non-respecting when a perfectly functional privacy-respecting alternative exists?

    Is it possible to see exactly which users liked, and disliked a post?

    In the official browser app, and any of the mobile apps that I have examined so far, it seems that you are only ever able to see the total number of likes, or dislikes that a post has, and you are not able to see exactly who upvoted, or downvoted the post. Does ActivityPub, or Lemmy track this information at all, or does it just keep a tally?

    (Please see comments)Alternatives to Signal if they exit EU due to ending E2EE
  • I have little to comment on regarding the motivation for your post -- I am not up to date with what's happening in the EU -- but, for an encrypted messaging-app alternative to Signal, I can recommend Matrix.

  • (Please see comments) Alternatives to Signal if they exit EU due to ending E2EE
  • I caution mentioning both Matrix, and Element as if they are synonymous -- they are not (I'm quite certain that that wasn't your intent, but the usage of the forward slash could be interpreted as such). It may lead to confusion for newcomers. It would essentially be the same as saying "I recommend ActivityPub/Thunder" to someone who you want to introduce to Lemmy. Matrix is the protocol, and Element is simply a client that interacts with the Matrix protocol.

    I personally think that it's sufficient to recommend Matrix if one is mentioning chat-app alternatives. Of course, nothing is stopping one from also recommending a client, but I don't believe that it's entirely necessary.

  • Births in China slide 10% to hit their lowest on record
  • Almost all countries need to reduce their population.

    On the contrary, actually, we need to increase our populations. Assuming that you mean an equal reduction in all demographics, the existence of productive, and hyper-productive people is mostly a game of statistics. A larger population means that more of such people will exist. Such individuals are necessary for pushing humanity forward. A nation with a larger population means a larger natural defence. A larger gloabal population decreases the chances of a mass-extinction event.

    it’s stressing the system.

    What specific stresses are you referring to? We have no lacking in resources, nor space. Economic activity is proportional to those acting within it.

  • Israel Deploys Semi-Autonomous Machine Gun Robot to Gaza Border
  • Tell me you can’t conscript or recruit more ground soldiers without saying so. 7.62 rounds are personnel ammunition.

    Israel running out of military personnel is hardly the only possible explanation. Furthermore, it's rather nonsensical to claim that Israel is running out of military personnel simply because of the type of ammunition that this robot's machine gun is chamebered in -- that is affirming the consequent.

  • What are your thoughts on the idea of adding an edit history feature to posts, and comments in Lemmy?

    I believe that the addition of an edit history would be a massive boon to the usefulness of Lemmy on the whole. A common problem with forums is the relatively low level of trust that users can have in another's content. When one has the ability to edit their posts, and comments this invites the possibility of misleading the reader -- for example, one can create a comment, then, after gaining likes, and comments, reword the comment to either destroy the usefulness of the thread on the whole, or mislead a future reader. The addition of an edit history would solve this issue.

    Lemmy already tracks that a post was edited (I point your attention to the little pencil icon that you see in a posts header in the browser version of the lemmy-ui). What I am describing is the expansion of this feature. The format that I have envisioned is something very similar to what Element does. For example:

    !

    What this image is depicting is a visual of what parts of the post were changed at the time that it was edited, and a complete history of every edit made to the post -- sort of like a "git diff".

    I would love to hear the feedback of all Lemmings on this idea for a feature -- concerns, suggestions, praise, criticisms, or anything else!

    This post is the result of the current (2023-10-03T07:37Z) status of this GitHub post. It was closed by a maintainer/dev of the Lemmy repo. I personally don't think that the issue got enough attention, or input, so I am posting it here in an attempt to open it up to a potentially wider audience.

    PSA: Do not enable URL thumbnail generation in Element

    As I noted within my post, #9955859@lemm.ee (alternate link), URL thumbnail generation in Element is an enormous privacy, and security vulnerability. Thumbnails are generated server-side, regardless of E2EE settings. What this means is that the URLs that one sends would be leaked out of your encrypted chats to the server. Here is a notable excerpt from the settings within Element: > In encrypted rooms, like this one, URL previews are disabled by default to ensure that your homeserver (where the previews are generated) cannot gather information about links you see in this room.

    Where are URL previews generated?

    I recently found that there is a room setting to enable the generation of URL previews. This makes me wonder, though: Who is generating the thumbnails? Does the server generate them, and then send the images back (this is an obvious privacy, and security vulnerability)? Does a user generate them locally, and send them to the other recipient (this is what Signal does)? Does the receiver generate them on their end (this is also a potential security vulnerability)?

    EDIT (2023-10-01T21:38Z): I found this documentation which outlines the possible methods, but, from what I can see, it doesn't specify what one is actually used in practice. I was also unable to find any information in the Matrix spec.

    EDIT (2023-10-01T21:41Z): In this set of release notes for Synapse 1.45.1, I found the following: > Note that URL previews are generated server-side, and thus generally disabled in encrypted rooms to avoid leaking information about message content to your homeserver. You may need to adjust the room's settings to see the new oEmbed previews.

    If this is true, and all thumbnails are generated serverside, this is an enourmous security, and privacy risk.

    EDIT (2023-10-01T22:18Z): Further research has found the following two open issues:

    This confirms my suspicion -- at the very least, for Element (I have still been unable to find any official standardized method within the Matrix protocol). My PSA that I would provide, then, to any who are reading this, is to not enable thumbnail generation, as it is a major privacy, and security vulnerability.

    Lemmy is licensed under the AGPLv3. I don't want to rely solely on my own legal interpretation of the license, so I'm wondering if anyone has any explicit knowledge on the matter.

    As an aside, am I correct in assuming that, if someone does make changes to the source code, they must host, and link to it?

    When sharing a post, or comment from lemmy, which link should you share?

    Say you have a Community on Instance A, a User-B from Instance B posts to that community, a User-C on Instance C comments on that post, and User D on Instance D is viewing that post, and its comments from Instance D. How should user D go about sharing a comment from that post? Should User D share the comment from Instance D, Instance A, or Instance C?

    Nextcloud files not displaying after restoring from a backup

    Workaround

    A workaround that I decided to go with was to simply extend my backup of the nextcloud snap to simply include the entirety of /var/snap/nextcloud instead of just taking the data directory, and the dump of the database. If I restore /var/snap/nextcloud, everything is immediately restored to its previous working order. This seems to accomplish what I want.

    I still have no idea what was causing the previous issue, though. I'm thinking that it might be that some important files, or directories are being left out in the previous backup that nextcloud is expecting to be present, but I'm really not sure.

    ---

    Original Post

    I have been scratching my head for hours over this -- I'm really not sure what the problem could be. I have nextcloud installed as a Snap on Ubuntu Server.

    Here's how I went about restoring the backup (fresh install of nextcloud):

    1. Copy over the data: # rsync -Aax data-backup data-directory
    2. Drop the existing database: # nextcloud.mysql-client -e "DROP DATABASE nextcloud"
    3. Create a new database: # nextcloud.mysql-client -e "CREATE DATABASE nextcloud"
    4. Restore the dumped database: # nextcloud.mysql-client nextcloud < database-dump

    When I log in to nextcloud in the browser, it initially appears that it worked fine: calendar data, task data, contacts, etc. are all properly loaded, and the images viewer is displaying images; however, when you look at the files tab, there's nothing there, and, when you try to create a folder, it spits out an error saying "Unable to create folder". If I run nextcloud.occ files:scan --all it can see all the files in the data directory just fine, it's just not able to display them in the files taband I cannot figure out why. I would really appreciate any help, ideas, or suggestions.
