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
Oops, yes. Thats what I meant. STILL died.
VoIP phone
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.
Technically, if it's a land line port and still connected to an exchange that hasn't gone completely VoIP (that's a thing where I am), it might actually be possible to build a charger module that plugs into that port.
Would it be worth it, though? ... No.
Low power is supplied over old land-lines for the purposes of making telephones ring and powering other handset bits and pieces, within reason of course. Using it for anything else is undoubtedly illegal as phone lines aren't rated for huge power draws.
(If you're interested, there are videos online where people have hooked up LED lamps etc.)
But, let's say that module existed and was legal. Your niece still wouldn't be happy with it.
To avoid burning out to the telephone line, any such device would have to be a r e a l l y s l o w trickle charge.
I wouldn't even think about it for emergency power outages. A battery backup is a better option.
Would it make you feel better that literally today I had to troubleshoot a RS-232 at work?
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.
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.
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.
I swear my kid thinks we were all hand starting our Ford Model-Ts before 2012 (his birthday).
Kinda like I perceive the 70s I guess. The dark ages, the before time before I existed.
Completely off topic to the thread, but you just reminded me of a time I snuck onto a movie set and got to actually do that. I posed as a driver for the car company and got to start/drive one of those bad boys with the hand crank. Inside was all switches too which was wild. The most uncomfortable ride of my life.
My kids are convinced that we didn't have cars when I was a kid. I was explaining to them what the before GPS times were like.
That movie is WarGames (1983)
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.
That's about the speed you can read text...it's why pre-internet sites like BBSes weren't all flashy, you had to keep it loadable. Actual downloads you would plan overnight and hope you didn't lose connection. The first big breakthrough was resumable downloading where you left off. Huge.
I have memories of watching pictures back then being transfered by modem. It was one pixel row at a time, being rendered at approximately reading speed. So as a teenager being into hot celebrity girls, I got to watch the image being unveiled during about 3 minutes of watching those pixels appear left to right, one pixel row at a time.
It was cool :)
You misspelled "RJ11"
There was a time computers had no text but instead had punch cards
There was a time computers had no punch cards, but switches.
There was a time when computers used to be African American
Founders of the information age. Some have called them "Hidden Figures".
PFY: "Hey, computers used to be all text just like that with no graphics, did ya know?"
BOFH: "No shit" uninstalls X/Wayland from PFY's computer remotely
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...
Terminals I played with had no screen just a dot matrix printer. My God, the sound...
Ah, the way god intended. GUIs were a mistake lol
Which console UI are you using for Lemmy?
I was taught Lotus 1-2-3 on MS-DOS in college. Do with that information what you will.
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.
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.
Green? Everyone knows AMBER MONOCHROME is the one true color!
I've seen those also, but the only ones I used were the green DOS ones. But you're right - they were both a thing, I forgot about the Amber colored ones!
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.....
