Pretty sure you can do much better than that now (plus or minus tariff insanity) – quick check on Amazon, NewEgg, etc. suggests ballpark of $5K for 1TB RAM (Registered DDR4) + probably compatible motherboard + CPU.

You can get motherboards with enough slots if you’re willing to pay enterprise prices for them. I have a system with 1TB of RAM at work that I use as a fast data cache. I just mount tmpfs on it, write hundreds of gigs of data into it (overwriting it all every few hours), and it works great. Cost was somewhere in the $10~15K (US) range a few years ago, IIRC. Steep for an individual, sure, but not crazy for an organization.

What they mean is you can just do something like mount -t tmpfs -o size=1G tmpfs /mnt/ramdisk to get a file system using regular RAM already.

What was the most ridiculous or funny boundary push you saw?

Trolling someone by attaching a camera to the ceiling right above their keyboard. I’ve been paranoid since I saw that stunt pulled… They got their point across about physical security though.

I’ve worked for a university before and it was very common for staff to remote into their systems from home – usually with SSH for CS types or Remote Desktop/Team Viewer/etc. for less computer-focused folks. (The former usually didn’t have much issue – the folks using the latter mechanisms got compromised a number of times… -.-) There was also a campus provided VPN that was required to access certain systems with instructions to students and staff on how to use it, but other systems just got public IP addresses.

If what you’re doing is related to your work and campus IT doesn’t object, you’re probably fine to do it. I’ve run various kinds of websites and web apps for colleagues to collaborate on research projects. Being able to do things like that is kind of the point of the internet.

Having seen a number of students, uh, push the limits and find the boundaries of acceptability the hard way though… I’d strongly advise you not to install cryptominers, run TOR exit nodes, or torrent TV shows/movies/etc. That kind of thing tends to get your systems in hot water with IT or other parts of the bureaucracy…

In principle, sure. I’m not aware of an existing out-of-the-box solution that’d do what you want, but it also wouldn’t surprise me terribly if someone’s cobbled something together to do this before.

If I wanted to make something like this personally (and couldn’t find an existing solution), I’d start by doing some research into PBX software like Asterisk, what derivatives and extensions people have made for that, etc. – being mindful that I’d likely be digging into a deep rabbit hole…

You can run docker containers with multiple volumes. e.g. pass something like -v src1:dst1 -v src2:dst2 as arguments to docker run.

So – if I understood your question correctly – yes, you can do that.

Giant middle finger from me – and probably everyone else who uses NoScript – for trying to enshittify what’s left of the good parts of the web.

Seriously, FUCK THAT.

Two quick ideas on possible approaches:

1. Static page route. You can just write some Javascript to load the image from a file input in HTML, draw it resized to a canvas (based on an input slider or other input element), then save the canvas to an image. (There might even be simpler approaches if I wasn’t stupidly tired right now…) This can be done in a single file (HTML with embedded JS – and CSS if you want to style it a little) that you toss on any web server anywhere (e.g. Apache, nginx, whatever). Should work for JPEG, PNG, and probably WebP – maybe other regular image types too. Benefit: data never needs to leave your device.

2. Process on server route. Use Python with a simple web server library (I usually opt for tornado for stuff like this, but flask or cherrypy or similar would probably work). Set up a handler for e.g. an HTTP POST and either pass the image into a library like Pillow to resize it or shell out to ImageMagick as others have suggested. (If you want to do something clever with animated GIFs you could shell out to ffmpeg, but that’d be a fair bit trickier…) The image can be sent back as the response. Be careful about security if you take this route. Probably want some kind of login in front of it, and run it in a VM or some other secure environment – especially if you’re using AI to kludge it together…

Best of luck and let me know if you need any help. Will probably have some time this weekend if you can’t get it on your own. Happy hacking!

I would be happy with a FOSS desktop app I can install in linux too

On the command line, you can do this with ImageMagick (e.g. use the command convert once it’s installed).

With a (desktop) GUI, there’s a bunch of programs. GIMP is probably the most well known and has a ton of capabilities but is a bit complex. I use Kolourpaint as a quick-and-dirty “MS Paint”-like program for very simple tasks where I want a GUI.

If you want a simple web UI I’m sure there is one already, but I don’t know one specifically. It wouldn’t be too complicated to hack something up if all you need is a quick-and-dirty file input and percentage rescale or something like that. If you don’t get a better suggestion and don’t know how to make something like that yourself, let me know and I can write an example.

People have already covered most of the tools I typically use, but one I haven’t seen listed yet that is sometimes convenient is python3 -m http.server which runs a small web server that shares whatever is in the directory you launched it from. I’ve used that to download files onto my phone before when I didn’t have the right USB cables/adapters handy as well as for getting data out of VMs when I didn’t want to bother setting up something more complex.
