  "client side validation is fine, nobody's gonna open up the dev console"

  No they didn’t, this is just a CVS receipt.

  • FlyingSquid@lemmy.world ⁨1⁩ ⁨year⁩ ago

    Are you sure? It doesn’t look long enough to be a CVS receipt.

      What you can’t see is that’s only about 6% printed

  Oh this reminds me when people discovered all the printers at school were available on the WiFi

    That’s incredible.

    Then again, school IT jobs are often given to “my nephew who is good with computers”, because the pay is often half compared to the private sector.

      One teacher told us that once an IT technician at our school built the network, connecting 2 school institutions with ~7 buildings using only hubs. That network was apparently almost unusably slow, which isn’t surprising.

      I have a friend that does IT/networking for a school district and he makes bank, YMMV.

    And not just printers. There may or may not also be a few Wi-Fi APs with login details admin:admin. And there also may or may not be many computers with RDP enabled without password. And those that have some password may or may not re-use the same short password for Administrator account. There also may or may not be SMTP server, though unfortunately in my case it doesn’t allow using it so send e-mails outside the network. It returns “Relay access denied” error.

    If it makes you feel any better, before the days of ubiquitous wi-fi, printers on wired networks in my school were about as easy to discover and use from a distance. FTPing a text file to one would start a print job for that file and it would be trivial to mash together that information plus a list of printer addresses for the entire district network (courtesy of nmap).

    This information was certainly never put to use.

    My school had a level of security on their printers…and also a shitload of hackers. Like, the IT department was reporting vulnerabilities discovered by the students to Apple amount of hackers.

    • Maggoty@lemmy.world ⁨1⁩ ⁨year⁩ ago

      My high school had a level of security too. The same password on every work computer in the school.

      Amazingly, I never resorted to changing grades. However logging into the admin account to play games instead of the 1,358th typing class was definitely on the menu.

  my brain is churning through char limits... i just cant believe it would be large enough through multiple systems..but then, i dont know the char count of the script, compression techniques used, encapsulation etc.

  • programmer_belch@lemmy.dbzer0.com ⁨1⁩ ⁨year⁩ ago

    It can just fetch the information one line at a time like a printing machine. I don’t think the receipt machine has that much memory to hold everything

  • wren@sopuli.xyz ⁨1⁩ ⁨year⁩ ago

    The script is ~55k characters long, depending on the source. This transcript includes who is saying the line, as well as descriptive elements of the story, so the actual ‘words only’ version will be a bit shorter. From what I’ve seen, though, most of transcripts have these non verbal inclusions, so the person who added it to the special instructions likely copied those over as well.

    I can’t speak to the other points, but allowing 55k characters is definitely wild.

  I do hope when someone reads about a Christian Nationalism lawsuit going on they don’t find out what law office is representing the guy who wants to hurt gay people. Then find the fax number on their site, go get a temp email at all the free sites that provide it, go to a send fax over the Internet site, and send them long faxes.

  source

  • Railing5132@lemmy.world ⁨1⁩ ⁨year⁩ ago

    An old trick you could do on old physical fax machines was to tape a couple of sheets of black construction paper together, feed them into the machine and tape them into a loop. Dial your special person and burn through all their toner. Of course, now it would just generate a bunch of emails.

    source

    • Agent641@lemmy.world ⁨1⁩ ⁨year⁩ ago

      Black fax - such an effective remote physical attack that fax companies had to actually hard-code a defence against it, to not print pages where there would be enough ink or toner dispensed that it could damage the machine or be a fire hazard

    Ok my copier story. We had a copier room in my high school with a little window in the door. I put a black sheet of paper on it, set it to copy 999 times, locked the door from the inside, then walked away. Turns out no one knows where the key was to the little copier room. I got caught and was punished. The end.

    Why do most of the comments in this thread match exactly with the comments in the linked reddit thread?

    source

    • GrundlButter@lemmy.dbzer0.com ⁨1⁩ ⁨year⁩ ago

      We’re not really that unique. We’re not consciously or likely even unconsciously referencing that thread or others like it. We’re just coming to the same witty conclusions those before us did.

      Even your comment comes up every time there’s a similar thread or experience. Mine too.

      Happy New Year, btw.

    Why not entire txt files containing several hundred random characters such that the entropy is high enough compression is useless >:) but maybe it’s preferred.

    • EmperorHenry@discuss.tchncs.de ⁨1⁩ ⁨year⁩ ago

      I don’t know what you’re talking about, I suggested the uncut extended LOTR trilogy scripts because each of those three movies are over 4 hours long.

  Set a character limit. Easy. A maximum reasonable length considering the attention span and efficiency of an employee to grasp such information if required should do the job
