    If you do self host I suggest reading carefully the Gmail guidelines for mails. They are the leaders in the field and they dictate the level of security required.

    DNS forward and reverse, DKIM, SPF, DMARC, ARC, DANE, bounce signature etc. Email is indeed a very complicated thing to host. I work on emails system all day and and I wouldn’t host my own mail.

    Even worse I’m hoping email disappear and another technology takes it place. Emails are unreliable and outdated, they need to go.




  • Have you checked when the file was last modified.

    If it fits the date you did the Spotify command then I wouldn’t worry much about it.

    If you still are concerned you can send the file to virustotal to be safe.

    If it’s more concerning for you for a functional reason then move the file elsewhere if nothing break you should be fine.

    Good job !

    I highly recommend trying out the various online regex editor.

    These WISIWIG kind of editors are great because you immediately see what the regex is catching and for what reason.

    I took the first one in my search results but try different ones.

    https://regex101.com/

    Also I used GPT to get some regex for some specific strings and it can be helpful to get a quickstart at building a specific regex.

    In that case I was building a regex for a specific log from postfix.

    PS: just make sure to select the correct flavor of regex you are using in these online tools.

    Edit: Also one of my favorite YT channels has pretty cool videos on RegEx : https://youtu.be/6gddK-cOxYc?si=0bnNkSDzifjdxwjU






  • Do you know if OP has certifications or experience?

    Do you know how knowledgeable he is on Linux ?

    Beside I will say it again, you can totally teach introductory courses on some subjects without being an expert on it.

    And in practice, I have definitely seen people teaching with tons of certifications and alleged expertise on the topic but who couldn’t teach anything. And that was of very expensive courses on rather specific Linux topics.

    I personally would much prefer to be introduced to a new subject (like BASH101) by someone who has zero certifications but some experience and a real ability to teach.

    Because I have seen a lot of super certified teachers who ends up unable to teach anything and who are recycling the same course without any practical experience in the last decade.


  • If you like teaching/training that could be an avenue to make money with some of that knowledge.

    You would need to consolidate that knowledge and show that you have a good enough understanding of that topic to teach it but it’s a pretty good way to learn more and make some money along the way.

    Not every training needs to be kernel level types of expertise, a lot of people train on the basics of Linux and could use some training. For instance many business will send admins that are knowledgeable on Windows to learn also on Linux so they can do both at the same time.




  • I’m usually pretty relaxed when it comes to disclosure of vulnerabilities but this is the kind of issues where I think it would have been better to privately report the issue to the Lemmy dev and wait ( a long time probably) for it to be fixed before disclosing.

    Especially since currently there is multiple people abusing the image hosting feature.

    Not a big deal, but sometimes it is actually a better practice to give an opportunity to the dev to fix something before forcing them to do so in a hurry.






  • In France at least I doubt it.

    The only time I remember caps on landlines was when 56k modem were still the norm. Once ADSL was rolled out there was pretty much no caps anymore.

    I think the fact that we had some healthy competition for landlines from the get go in my country meant the ISPs couldn’t get that much greedy and put caps in place. So it never ended being common where I live.

    And when it was old school modems, well you were already paying for the phone communications anyway when connected to the internet so it wasn’t really unlimited anyway.

    Sorry if this is nitpicking but as far as I know, there is no such thing as unlimited mobile data plans.

    In most contracts they will say that you have to use reasonably the data plan and you cannot for example constantly max out your connection. Like 24/7 constant max bandwidth used.

    In most case it doesn’t really matter but I really don’t like the fact that ISPs get to say it’s unlimited when it definitely isn’t.

    It’s unlimited*
