Comment on I'm locked out of my 6 year old Chipotle account because they now say my email address is invalid when I login. Here is me asking for their help:

• dan@upvote.au ⁨11⁩ ⁨months⁩ ago

  You can use symbols like [ ] . { } ~ = | $ in the local-part (bit before the @) of email addresses. They’re all perfectly valid but a lot of email validators reject them. You can even use spaces as long as it’s using quotation marks, like “hello world”@example.com.

  A lot of validators try to do too much. Just strip spaces from the start and end, look for an @ and a ., and send an email to it to validate it. You don’t really care if the email address looks valid; you just care whether it can actually receive email, so that’s what you should be testing for.

    Not even a dot: TLDs are valid email domains. joe@google is a correct address.

      Mmm… That doesn’t seem right, it’s usually gotta be fully expanded to at least a particular A record/MX.

      How would you tie the tld itself to an MX?

        TLD is just another DNS layer, try an SOA or NS lookup for “com.” those are obviously hosted somewhere. Hell the “.” at the end is even another layer with the root nameservers. You’d probably trip up a bunch of systems that filter on common convention rather than the actual RFC, but you could do it.

    To this point, there’s a website dedicated to the subject. Some of the regexes get pretty wild…

    emailregex.com

    Yea but most of the time its more important to block code injection than to have the last promille of valid mail adresses be accepted.

      You’re not going to get code injection via an email address field. Just make sure you’re using prepared statements (if you’re using a SQL database) and that you properly escape the email if you output it to a HTML page.

      I think emailregex.com offers best of both worlds.

  interesting if you’re interested in the topic

  That is AI…

    Even “algorithm”, you could say! The text adventure game I made in BASIC when I was 14 is going to blow your mind. It is 100% artificial and uses logic (IF statements), hence AI!

  Yeah, that video is great. He has a lot of interesting and funny talks like that.

  Nah, it’s just a old school chat bot following a predefined flow chart. And in this flowchart someone implemented an improper email check.

  yes but that would be an AI still

  • stom@lemmy.world ⁨11⁩ ⁨months⁩ ago

    A bunch of IF statements don’t qualify as an AI. That’s not how that works.

    source

    • force@lemmy.world ⁨11⁩ ⁨months⁩ ago

      I don’t think you know what AI is. A bunch of if statements can, in fact, constitute an AI. You don’t know what you’re talking about, stop trying to pretend you do.

      AI is a broad concept, a pathfinding algorithm can be considered AI, a machine learning image generator can be considered AI, a shitty chatbot (like this one) can be considered AI. Reducing something to a stupid sentence like “just a bunch of if statements” to try to make it seem absurd is. I can reduce something like ChatGPT the same way and it’d be pretty much as accurate as your take.

      • stom@lemmy.world ⁨11⁩ ⁨months⁩ ago

        Selecting a canned-text response based on simple keywords is a long way from AI, and it’s foolish to equivocate the two of them.

        Also, chill tf out, and don’t be so aggressively presumptious. I have enough experience with the topics in question to point out how misleading this statement is.

  The problem is their website also implemented an invalid email check when I try to login which is what got me to this point
