I assume most of those students weren't "officially" given admin priveleges, which makes it extra funny

[-] [email protected] 78 points 7 months ago

They may have been, things were far more trusting back then.

X servers, for example, would accept any connections. So we would often "export DISPLAY=friendscomputer:0.0" in the computer lab and then open windows of embarrassing content. Which at the time would likely be ASCII art....

One of my favourite wars was to open audio files on other people's SPARCs, somebody had the loudest bag pipe music that usually ended things.

Access to the SPARCs was normally restricted to third year but if you knew the right person you could get an account created pretty easily. Had the fastest access to the internet at the time within the uni as well.

I used to work at a company that did distributed QA. Other people's tests would run on your desktop. It worked surprisingly well. But occasionally a test of some audio resource would play on your speakers "The discrete cosine is a real, discrete version of the fast Fourier transform."

[-] [email protected] 1 points 7 months ago

Ha, love the audio tell of the resource stealing

[-] [email protected] 8 points 7 months ago

Still can. Only a few years ago, I would cat random things to classmates' tty devices.

Little known fact: A Stanford mainframe kept logs of the activities of the 'wheels' in a journal -- the 'journal of the wheels'. Young George Lucas, who briefly attended the university, found that journal, and became fascinated with the 'Wheel Wars'. He later drafted a document that he called 'Journal of the Whills', based largely on what he read on those logs; this is the draft that later became 'Whill Wars', and ultimately, of course, 'Star Wars'.

I have no idea if this is true, but I'd be impressed if you just made it up.

[-] [email protected] 33 points 7 months ago

Thanks indeed; but I think I'd be more impressed if it were actually true.

(but yeah, the first draft of Star Wars was called 'journal of the whills'.)

[-] [email protected] 10 points 7 months ago

... So... Is it true or not?!

[-] [email protected] 19 points 7 months ago

It's true. You can trust me, I'm a doctor.

[-] [email protected] 5 points 7 months ago

I’m a doctor not an escalator…

Wait wrong Star show.

The best part of working in a meat grinder startup were the Linux masters teaching you stuff like

cat /dev/random > /dev/pty23

or

su _otheruser_
chsh -s /bin/false
[-] [email protected] 21 points 7 months ago

What is /dev/pty23? From context, I assume another users terminal so it just spams garbage to their screen?

[-] [email protected] 16 points 7 months ago

cat /dev/random > /dev/pty23

Imagine someone adding this to your .profile

In my freshman year of computer science our main computer lab was filled with Sage IV machines. Basically a Motorola 68k series with 4 or 5 serial terminals. Most people were writing Pascal code or using a simple word processor. But god forbid you were on there with someone taking assembly language. Because they could write really stupid code with super tight loops that never allowed any other code to run, and the only thing you could do was reboot. So if you hadn’t saved your code you were fucked.

So I never purposely wrote really bad code that would overwrite unprotected shared memory with random quotes from Marvin from HHGTG to mess with other people. I would never do that. That would have been unethical and shit… 🤔

I did learn a lot of basic hardware and operating systems though so there’s that.

In my town's school classes during Covid lockdown were held in Microsoft Teams. But there was a severe lack of IT knowledge. In the beginning, for some reason all participants ended up with moderator rights, so kids kept kicking the teacher out of their lecture.

[-] [email protected] 16 points 7 months ago

We had similar issues and they disabled kicking participants. However, they didn’t disable muting teachers for another week.

[-] [email protected] 32 points 7 months ago

I remember back in college we would abuse the wall command on our shared Linux server so much that IT had to disable it

I've always wondered why the admin group is called wheel

[-] [email protected] 37 points 7 months ago

It's from the phrase "big wheel", meaning a person with a lot of power/influence. Similar to "big cheese"... It would have been better to use "cheese" instead of "wheel" IMO.

[-] [email protected] 29 points 7 months ago

What if wheel referred to a wheel of cheese? Best of both worlds that way!

[-] [email protected] 9 points 7 months ago

I always think of it as 'being behind the wheel', which gives control of whatever direction you want to steer into.

[-] [email protected] 2 points 7 months ago

Pretty sure it's not. I saw something on this topic a few weeks ago but can't quite remember. Iirc, it was a term in an early early OS, where a bit in memory was the privilege but and could be set or unset by turning a real wheel on the computer. This Stück with some people developing UNIX, so they called the wheel group wheel, but none of them are sure who came up with this.

Of course, this is just hearsay.

Here is an alternative Piped link(s):

Piped is a privacy-respecting open-source alternative frontend to YouTube.

I'm open-source; check me out at GitHub.

Reminds me of the "Op" wars on IRC. All users would be given @ status and the point was to kick everyone before you got kicked. Writing scripts for this was my first "taste" at programming.

[-] [email protected] 22 points 7 months ago

Reminds me of the test server shenanigans I had at an old job versus a colleague. All in fun. Nothing in production.

One was the faux Bash shell that kind of worked OK until you pushed it or tried to do anything fancy. It was the default shell for the user called "root", but that wasn't the UID 0 user. It had been, but I renamed it. Then created a new "root" with a different UID. Of course, the faux shell would tell "root" that it was UID 0.

The other was the simple background loop that would detect any rival admin sessions and SIGHUP their shell process. First user on the box to run that pretty much had free reign, and everyone else was logged off instantly.

Why declare a war over it? Just sudo sed -i 's/%wheel/$(whoami)/' /etc/sudoers or smth like that

[-] [email protected] 8 points 7 months ago
[-] [email protected] 7 points 7 months ago

got a similar situation in MUDs, someone finds a way to frob everyone else up to wizard level and the whole round of the game just becomes a mess of shouts

[-] [email protected] 3 points 7 months ago

$ usermod -G wheel lntl

i think that's right

[-] [email protected] 4 points 7 months ago

Need to throw a -a in there otherwise wheel will be your only extra group.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
