YSK - for all the things that can make your life easier!

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with YSK.

All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.



Rule 2- Your post body text must include the reason "Why" YSK:

**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-YSK posts.

Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you harass or discriminate against any individual member, you will be removed.

If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- The majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.



Rule 11- Posts must actually be true: Disiniformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated.

If you file a report, include what specific rule is being violated and how.

So if you do the Docker setup, obeying the instructions and substituting everything that needs to get substituted, but don't proofread the files in detail and so miss that line 40 of docker-compose.yml doesn't have the variable {{domain}} like in every other location you need to write your domain, but instead just says LEMMY_UI_LEMMY_EXTERNAL_HOST=lemmy.ml and so you fail to change it away from lemmy.ml... then, everything will work, until you type in your admin password for the first time, at which point your browser will send a request to lemmy.ml which includes your admin username, your email address, and the admin password you're trying to set. And, also, of course your IP address wherever you are sitting and setting up the server.

I have no reason at all to think the Lemmy devs have set their server up to log this information when it comes in. nginx will throw it away by default, of course, but it would be easy for them to have it save it instead, if they wanted to. And my guess is most people won't use a different admin password once they figure out why creating their admin user isn't working and fix it.

@dessalines@lemmy.ml @nutomic@lemmy.ml I think you should fix the docker-compose.yml file not to do this.

Edit: Just to increase the information-to-rudeness ratio of my post. The docs are at:

https://join-lemmy.org/docs/administration/install_docker.html

And they recommend using wget to download:

https://raw.githubusercontent.com/LemmyNet/lemmy-docs/main/assets/docker-compose.yml

Which is pulled from:

https://github.com/LemmyNet/lemmy-docs/tree/main/assets

Which is what has the wrong line 40 in it.

Edit: They fixed it. Good stuff.

Yes, there are still some problems with the self-hosting docs

Because people make mistakes and nobody is perfect and even paid software has problems?

oh for fuck's sake. A mistake is rendering the wrong emoji. Sending your password to elsewhere is inexcusable

[–] JackbyDev@programming.dev 1 points 6 days ago

I'm not saying it's excusable. I'm saying it's understandable. The cause of this was essentially a typo. I seriously don't believe it was intentional. If you have that big of a problem with it, please consider volunteering your time to write some technical documentation for the Lemmy devs.

You should edit your post with link to this PR - it's fixed now

[–] AusatKeyboardPremi@lemmy.world 120 points 1 week ago (1 children)

Thank you for discovering this, and creating awareness around it.

Seems like a genuine miss, contrary to what the comments here would have one believe, given that the compose file (and rest of the docs) were mostly derived from whatever worked for the developers themselves.

[–] PhilipTheBucket@ponder.cat 35 points 1 week ago (2 children)

You might be right. I looked at the history and the way it came in, and it's not as wildly anomalous to the rest of the file when looked at in context. Maybe it's just a mistake.

[–] mojofrododojo@lemmy.world 2 points 6 days ago (1 children)

if it was inadvertent you'd think someone at the receiving address would have spoken up....

[–] PhilipTheBucket@ponder.cat 0 points 6 days ago (1 children)

Well, part of the price I pay for being a consistent dickhead is that sometimes people aren’t enthused to respond to me. I get why they wouldn’t really want to respond here and get yelled at, whether or not it was malicious, and instead just fix it and go on.

In my opinion it would be a healthier way to go about things if they were willing to meet criticism head-on, but the pro-authoritarianism position they’ve staked out for themselves is so widely and bitterly unpopular that I think that ship has sailed and they’re unlikely to engage with most of the free-speaking world at this point, because it would just be a torrent of abuse and mockery and so what would even be gained by it.

side effects of never letting a good opportunity to red bait go to waste I guess

That’s so on-character for .ml

[–] PhilipTheBucket@ponder.cat 76 points 1 week ago (10 children)

The longer I look at it the more suspicious I am of it, to be honest. I'm just kind of generally a paranoid and accusatory person, so take that into account, but... the files are pretty carefully set up. They have variable substitutions for everything, including a bunch of places where there's a template substitution to change a string around when setting cache keys so that it'll still work out-of-the-box right away, even in complex configurations like multiple domains on a single server. It all works out-of-the-box right away, they've clearly been attentive to making sure it's all set up right and keeps working cleanly as things have been evolving forward. Except for that one place.

Im loving that there are ml users coming in and defending it lol

[–] PhilipTheBucket@ponder.cat 14 points 1 week ago (1 children)

Yeah, don't they realize they could have just spent that time productively by making a pull request, instead?

[–] TachyonTele@piefed.social 45 points 1 week ago (1 children)

Honestly, you found the fault. I agree that you should put the request in.

[–] PhilipTheBucket@ponder.cat 16 points 1 week ago (4 children)

I mean probably I should. There are a bunch of people accusing me of being dick headed and petty and they're not completely wrong. Honestly, I just don't feel like helping the Lemmy devs. Dessalines, at least, is totally unapologetic about being a dickhead to people he has power over. That puts me in a mindset where, mostly, I want to talk to other people about potential harm he's in a position to do, and not really in a mindset where I want to do even a small amount of extra work on his behalf.

I'm going to tell other people that he's in a position to take their passwords. If he wants to see that and put himself not in that position anymore? Great, I think he should. If he gets his feelings hurt because I'm not being super friendly about it? Well.. okay. I'm not trying to be malicious about it or do anything other than clearly communicate the problem. But it seems like the lemmy.ml "in charge" crew in general has a lot of a mentality that's kind of like, "Well, I'm in charge, and you're not, so fuck what you think and fuck your rights. Ban." (or whatever). The way I operate is that really makes me not want to be extra friendly or courteous to people. I used to have a regular donation to Lemmy development set up, I used to take it seriously the idea of getting involved in contributing to the code, and then I observed how they operate, and ... like I say I'm mostly talking to the other people involved who I think should be aware of this. If the devs want to react, fix it, or get involved in the conversation, then sure, sounds good.

The fix is in the comments below, if someone else wants to contribute it and do the very small amount of work of getting it in.

[–] percent@infosec.pub 19 points 1 week ago* (last edited 1 week ago) (4 children)

It sounds like a pull request would have been much more helpful, with much less effort. But you want it fixed less than you want it publicized, so you chose this option (even though you could have done both).

In other words, you cared less about the people impacted by this problem, and more about your own opportunity to put the author(s) on blast like this.

And you care about that opportunity so much, that it's even worth it to show this dark side of yourself publicly.

Am I understanding that right?

[–] BassTurd@lemmy.world 17 points 1 week ago (4 children)

Or OP is spreading the word to get it out there. Now it's got eyes on it thanks to OPs work.

Jesus. Some of you people just want to shit on someone for doing a good thing for no reason. Have you put in a pull request yet or are you just showing your dark side on top of being a dick to OP who did something good?

Well, you are, while I am on PieFed:-P If you do not like what you've heard here, then consider switching to Piefed.World (Lemmy.World's recently-announced PieFed replacement for Lemmy)

Why are you assuming malice when this is probably just a mistake/oversight?

[–] socsa@piefed.social 36 points 1 week ago (8 children)

Because of the way Dessalines and Nutomic consistently act?

Watch. They won't apologize or admit wrongdoing here. They never do.

[–] eugenevdebs@lemmy.dbzer0.com 22 points 1 week ago

They did patch it just now.

Why make a Lemmy post about this and not just a GitHub issue?

[–] PhilipTheBucket@ponder.cat 114 points 1 week ago (4 children)

I think it should be more public knowledge than just people who peruse the github issues. Also, it's so trivial to fix that it will save them some time if they don't have to close the issue after they spend literally 10-15 seconds fixing it.

[–] limer@lemmy.dbzer0.com 93 points 1 week ago (38 children)

I think you should also make a GitHub issue too

I'm reminded of stories I've heard of graduate students hiding a note and some cash in the pages of their theses that they submit to the university, just to see if anyone bothers reading it and takes the cash. They return years later to find it still there.

With open source, the code is all there ready for review by anyone, as long as you have the technical knowhow and patience to review the code you use. But like reading the terms and conditions for everything we use, how many people actually take the time to go through all that code?
