    Kid told me that he just watched "some crazy old movie" about how a kid hacked into NORAD.

    My 10 year old niece asked me what my RJ45 wall socket was while I was fixing her mom's computer.

    "It's for old telephones"

    She then asked me if I had an adapter for it so she could charge her phone.

    I almost died.

    Rj11/12 are for telephones, rj45 is for ethernet

    [–] jaschen@lemm.ee 31 points 9 months ago

    Oops, yes. Thats what I meant. STILL died.

    Won't work anymore. Our phone line is completely replaced with fiber. On the other hand i can't remember any unwarned outages in the last 20 years.

    Would it make you feel better that literally today I had to troubleshoot a RS-232 at work?

    [–] AVincentInSpace@pawb.social 11 points 9 months ago* (last edited 9 months ago) (1 children)

    RS232 is functionally immortal. Its market share in the niches it fills has never -- and I'd argue will never -- go away, or even shrink all that much. It's like those lobsters that don't age at all but if we splice the genes that do that into humans it gives us cancer.

    [–] afraid_of_zombies@lemmy.world 4 points 9 months ago

    Comparing RS232 to cancer is a good analogy.

    I hate it but as you said it has its niche and there really aren't better options for what it does. If someone else has a means to wire up +100 sensors to one system that doesn't involve enough wiring to encircle an entire city or an unbelievable reliable means to do M2M between two machines that's secure simply because everyone who knows how to tap it has a high paying job I am all ears.

    [–] NaoPb@eviltoast.org 7 points 9 months ago

    Could work in theory. Back then there it had sonething like 40 volts going through the line and you needed some decent power to make the bell in the phone ring.

    But I don't know if that's still in use these days.

    [–] Clent@lemmy.world 1 points 7 months ago

    Those old POTS phone lines did carry a few volts.

    The kid was blown away by the modem. For those who don't know it's a cradle type dial up modem where you place the (land line) phone on a receiver instead of plugging the computer into the cat4. You could get up to 150 bits per second on one of those bad boys.

    Oh God am I old now? I never had to use one but know of their existence from said movie.

    I've not seen some of these words in decades.

    There was a time computers had no text but instead had punch cards

    [–] sundray@lemmus.org 29 points 9 months ago (2 children)

    There was a time computers had no punch cards, but switches.

    There was a time when computers used to be African American

    PFY: "Hey, computers used to be all text just like that with no graphics, did ya know?"

    Ah memories from BOFH! I used to read that on the 90s

    Don’t know what the equivalent is today. But that one solidarity Commodore Pet, green screen glowing in the corner of the classroom, will always have a special 32kb space in my heart.

    And before that they was just paper and holes...

    [–] Hikermick@lemmy.world 11 points 9 months ago (1 children)

    Terminals I played with had no screen just a dot matrix printer. My God, the sound...

    [–] AnUnusualRelic@lemmy.world 3 points 9 months ago (2 children)

    I only used one of those once, it was atrocious. People must have shed tears of joys when screens took over.

    [–] Hikermick@lemmy.world 1 points 9 months ago

    I'm pretty sure the trees get a little dance. You'd have an entire ream of paper on the floor after playing a game of star trek.

    [–] bluewing@lemm.ee 1 points 9 months ago

    But playing Oregon Trail was never the same again......

    [–] lolcatnip@reddthat.com 6 points 9 months ago

    Which console UI are you using for Lemmy?

    [–] niktemadur@lemmy.world 7 points 9 months ago (1 children)

    I was taught Lotus 1-2-3 on MS-DOS in college. Do with that information what you will.

    [–] bluewing@lemm.ee 3 points 9 months ago

    Ahhh, Lotus 1-2-3... I remember it well. But first I had to master AutoCAD Release 9 in DOS.

    I was so sure MicroSoft could NEVER replace Lotus Notes.

    [–] bluewing@lemm.ee 4 points 9 months ago

    You young whipper snappers and your fancy DOS terminals.....10,000 years ago I sat at a teletype terminal and tried to learn to program in BASIC. Oregon Trail and Missile Attack are a whole 'nother experience when done by printed media only.

    I can still hear the sound of the teletype clacking.....

    [–] tygerprints@kbin.social 1 points 9 months ago (2 children)

    It's true. There was a time when Computers were just green screens with DOS text. Those are the first computers I ever used and we thought they were amazing. I thought it was amazing when I could put Star Trek After Dark Screensavers on my Power Mac! We've come a long way.
