Caveat: I'm following up with my vet for most of this, but she's newer and is having to do a lot of consulting with other vets in the practice.

Info: I have three cats,

• adult female - Nova, 13ish?
• adult male, Pippin 3ish
• male kitten - Fig 5 months (he's very sneaky)

Ok so, my girl Nova has been diagnosed with diabetes. This has entirely upended our feeding schedule and she's not coping well with it. We'd previously used some automatic feeders that dropped food 6 times a day, because she would stress out about not having food and then overeat and would throw up in both scenarios. But now all three cats are on different food (all kibble), and at least Nova would prefer to eat any food but her own, or have seconds, but the others would too if left to it. So they're being fed in different rooms at the same time.

Nova is ravenous, aggressively trying to drag her bowl out of my hands, headbutting the tub of her food (she caught it loose once) across the floor, running to the other bowls in case there's CC. food left once they're separated. She just dove for one as I was trying to just let a cat out of the room instead of pick the bowl up. She's always under my feet in a way that she used to be good about avoiding. I've stepped on her several times, and hurt my ankle and wrist last night catching myself.

Any suggestions for the perpetually (thinks she's) starving cat? I just got her a glucometer and am figuring it out but haven't been taught how to adjust her insulin as of yet.

Part of the difficulty here, and another area I need solutions in, is that she'll (mostly) inadvertently scratch my partner's leg when she wants his attention usually to be fed. I think occasionally it's intentional but he uses a wheelchair and mostly can't feel the leg - a cut can be dangerous for him, but also sometimes the touch/pain sets his leg off in a spasm cycle that is incredibly painful. On a bad day he's feeling guilty for how angry he is at her and is afraid he'll hit her (he probably wouldn't, but he doesn't have the control to say intentionally tumble her like a mama cat to a kitten, and she would probably claw or bite if he tried plus she's been sick and he's already afraid of hurting all the cats with the chair.) he's done the spray bottle thing in the past, she likes water and we know it's not ideal, but it's usually something that happens when he's not looking or can't see or hear her til she gets him.

Finally I need a better storage method for the food. Something she can't headbutt open or into dropping food, but that I can leave out in an open space. Currently I have a bag in a bathroom vanity, a tub of the Rx food in a spare room, and a bag in a closet. They have torn the bags open in the past (working together as a team, I suspect) when they're not secured.
I've thought about the microchip feeders but the youngest isn't chipped yet and frankly they're really expensive.

Summary of Asks:

• Help with a diabetic cat who's perpetually starving
• Help with getting a cat to stop scratching a human's leg who can't see it coming (addressing the first might help)
• Help with ideas for cat food storage/dispensing that would be more accessible than 3 bags in 3 closets in 3 rooms, two of which my partner can't access.

Bit of a vent here too, just everything is expensive right now too so I'm trying the best I can. Pics added.

Background: I started daily driving Linux (specifically Mint) several months ago and for the most part it's been great. Some weird hiccups occasionally but nothing I can't handle/deal with. When doing my research to set the system up for the first time, I decided to go with 30GB for the / partition and ~220GB for the /home partition (the other half of the drive is for Windows 11 and the various essential tiny partitions). For a while this seemed to be fine, but lately I've been starting to get warnings when performing software updates via the Update Manager that the / partition is running out of space. I think it peaked at maybe 90-95% full a few weeks ago, at which point I started doing some research and cleaning up a bit (apt autoremove, deleting old logs and kernels, etc). I was able to claw back ~4GB and kick the can down the road, but now the warnings have returned and I'd like to handle this properly. I'm working from the assumption that I simply made the / partition too small and intend to double it by giving it some of the Windows space.

My question: How do I know if this is expected or if I've been doing something wrong? Is 30GB indeed too small on modern Mint, or should that have been enough? I know it partially depends on what all I actually do with the computer, but I really don't have very many applications installed (aside from defaults of course) and only four of them are Flatpaks, which I read tend to be larger. If it helps, the Disk Usage Analyzer reports that within /, /usr is taking up 13.2GB (55%), /var accounts for 9.1GB (38%), /opt is 1GB (4%), and everything else is <1% each.

Thanks in advance!

Just something I was frustrated by ever since it became increasingly common even outside of smartphones and tablets.

For a few years now I increasingly see basically any battery powered product having mostly internal accumulator options(aka proprietary battery of uncertain ability to replace), especially in more expensive items in the category. Why?

I mean do see several advantages from the business side, I simply have no idea what advantage would there be for the actual user.

I could see it if the batteries had comparable lifespan to the product, which they most definitely do not unless the item is of truly bad quality.

I bought an M2 Macbook Air at the start of this year for uni. I only planned to use it for uni work as I have another 'more powerful' laptop that I use for everything else, but I kinda love the M2 and want to make it my daily driver laptop. Battery lasts for ages, screen is great, it's thin and light, etc. The problem is - as you might guess - I only got the 512GB model and if there's one thing Apple hates, it's people having control over their hardware, so no expandable storage. I can't afford to upgrade the entire laptop, so I need to work with what I have. Here's what I want to use it for:

• Graphic design: Adobe software, high-res images, typefaces, etc.
• Music production: Ableton Live 11 Suite, sample packs, plug-ins, project folders, etc.
• Music library: uncompressed .m4a files because iTunes hates Vorbis 😢, ~80% of my library (I don't have everything downloaded yet) is 25GB.
• Web-browsing: Firefox... this one isn't really relevant but I feel like I should include it for completeness.

Does anyone have any tips to stretch this 512GB as faaaaaar as it can go? I have a 2TB external SSD, but I'm wary of keeping anything important on it because it's small and I don't want to accidentally lose a bunch of stuff. I can spend a bit of money (maybe 30usd) if anyone has a good idea that requires buying something, but I can't spend any ludicrous amounts, I already did that to get the laptop!
