Everything interesting on twitter takes more than one tweet.

I wonder if there's a place for "fast Usenet", where you can write a message of arbitrary length with some markdownish syntax, let it be flooded to anybody subscribed to that group, and automatically drop into a searchable no-new-comments archive after, say, a week.

I graduated last year, and I worked for my colleges IT department. We used to have to come knocking at the door if a student even had their own printers set up. It definitely would not go well. That being said, I did know people who clogged the cs department's machines with batch jobs to train really expensive ML models that did God knows what.

> We used to have to come knocking at the door if a student even had their own printers set up. What's wrong with having a printer?

If I had to guess the wording of completely insane contracts signed with companies that provide campus wide printing.

Printers used to be expensive and noisy.

In 1993 I was one of about 3 people on a dorm floor of ultraturbonerds who had a printer in my room; it was a Canon BJ130, I think, which had the distinction of being a tractor-fed 300dpi black-and-white inkjet, and thus much much quieter than my friend's IBM ProPrinter 24XL. How much quieter? It wouldn't wake up people in the next room.

AtEase?

Holy shit. Just seeing that written out turned a light on in dark corner of my memory. I had completely forgotten about that until you mentioned it.

Same. It's always a weird jolt when you're reminded of something that you not only forgot, but that you "forgot that you forgot".

I remember AtEase, and remember hating it.

> But they were running some kind of secure software that didn't give you access to the Finder, only specific software, so I couldn't pop in a disk and run my own programs.

That software would be AtEase. And I used to run circles around it trying to break out into Finder and gain access to the nascent, to me, Internet. One of the first things I installed was NCSA Mosaic. Good Times!

Apart from using hacking to overcome imposed limitations such as these, I am amazed by the number of times I had to use my chops to overcome what was simply a bug. Opening the web inspector is such a normal moment of dealing with other people's websites, I have no clue how people manage without it. I was very... surprised when I managed to productively use "javascript:(some code)" in the URL bar of the browser of my…

The web is broken. Someone's website wouldn't scroll (I don't remember the details, and I don't think I wanted to find out --- maybe it was overflow: hidden, but it could've been something else), and the only way I could figure out to deal with it was to open up the devtools responsive design mode and pretend the screen was bigger than it was so that the full page could show, and then use the browser's scrollbar from…

I’m one of the few weirdos who actually seeks out and reads the ToS & privacy policy posted on sites I visit and I can’t tell you how many times I’ve run into a site with infinite scrolling and a footer (with all the “important” legal stuff) that a user will never see but for a fleeting moment. A feature or a bug? I’m never quite sure.

Funny, because I remember bypassing my university's print quotas in grad school a few years ago simply by printing directly to the IP of the printer. I didn't set out to do this. It was just an unintentional side effect, and one I never abused, but I did happen to notice that whenever I printed, my quota allotment never went down.

LPR is a pretty ancient and basic language. And it has 0 security!

From what my college-going friends tell me, some colleges want students to pay for a higher print quota instead of having their own printer. More money for the college that way.

I'd like to clarify that my code was running only on machines that were otherwise idle. Not many people were in the lab late in the evenings. MPQS processing nodes could be added and removed dynamically, so if somebody needed a computer that was part of my cluster, they could just quit my program and everything would go back to normal. Also, once the number theory professor learned of what I had implemented, he worke…

> I could enter that program in the system monitor, but I needed a way to run it.

The simple way: in that mini debugger, the ‘G’ command (for ‘Go’) takes an optional address and jumps to it. “G 40F6D8”, for example, continued execution at address 40F6D8.

I ocassionally use it to debug faulty script submission or stuck websites or some paywall banner (as a consumer), but one great way to manage without it, is to avoid those websites in the first place.

If I see an incompetent business website, I take my business elsewhere...
