I’m surprisingly level-headed for being a walking knot of anxiety.

Ask me anything.

Special skills include: Knowing all the “na na na nah nah nah na” parts of the Three’s Company theme.

I also develop Tesseract UI for Lemmy/Sublinks

  • I’ve had pretty good experience with Nextcloud’s instant upload. The only time I’ve had it shit the bed was ages ago when it would occasionally get stuck on a conflict, but that hasn’t happened in a long time. Pretty much all of my image folders (camera/DCIM, Screenshots, Downloads) get synced. The only annoying thing was when apps would suddenly change where they download to and I’d have to reconfigure yet another sync folder, but I can’t really fault NC for that.

    Mine is set to upload and keep a local copy and only do a one way sync (phone to NC). Not sure if that causes less issues than a 2 way sync or deleting the local copy after upload?


  • I suspect zram’s swap device only consumes RAM when it actually contains swapped pages, but I don’t know for sure. Can anyone link an authoritative statement on this?

    I’m wondering the same. I haven’t read anything authoritative, but it definitely seems like it only consumes the RAM it’s using. Otherwise, it wouldn’t be able to create block devices that exceed the physical memory. I started to wonder when I had it set to 50% (4 GB) and gave it a stress test. The 4 GB it allocated filled up but was compressed to just about 1 GB, so I thought “surely this isn’t wasting 3 GB of RAM to hold 1 GB of pages.”

    The guidelines I’ve read seem like there’s some guesswork involved in the planning. Basically you can make the zram device as large as you want so long as the compressed data is less than the physical RAM (not all pages compress equally as you mentioned).

    I’ve since bumped it to 200% of system ram (16 GB), and I think that’s probably good enough for my use cases. I’m seeing about a 4:1 average compress ratio, so I could go higher, but 8 GB has been plenty usable up until now. :shrug: I also left the original swap file in place with a lower priority as a spillover (I’m not really missing the 4 GB of disk space that uses, so might as well keep it).





  • Yeah, I found that out when I was using my old phone with T-Mobile. It was listed as supported, and it mostly worked, but there was at least one LTE band it didn’t support.

    T-Mobile uses multiple bands in the same area: one higher frequency, higher bandwidth, lower range one for fast data and a lower frequency, lower bandwidth higher range one to fill in the gaps. My phone didn’t support the lower frequency one so I would lose coverage if I was too far away from a window in my house (despite living close to 3 towers).

    Not to mention, they can and do reallocate spectrum periodically so while you may be fine for a while, if they reallocate and the device doesn’t support the new bands, you may suddenly lose service.


  • TL;DR: If it’s listed as Verizon-incompatible, treat it as such.

    It should work, technically, but there’s no guarantee. While Verizon shut down their CDMA network in 2023 and everything uses 4G/VoLTE now, it may have other limitations that prevent it from working as expected.

    You’d need to make sure the LTE bands it supports are used by Verizon in your area. If it doesn’t support the bulk of Verizon’s bands, you may find yourself (artificially) without coverage.

    Verizon may also refuse to allow it if it’s not on their compatibility list (though you can possibly SIM-swap into it from an already activated device). It’s been a while since I dealt with them, but from memory, they’re pretty strict about what devices they allow on the network.




  • Good. May other retailers and grocery chains follow.

    I hate those things - they treat you like a thief by default. I rarely use them and prefer to wait in line for the 1-2 cashiers, but I did the other day because I only had a few bottles of water to check out, and it was unsurprisingly horrible.

    Scanned and bagged all my stuff. More slowly than I’d have liked, but otherwise uneventfully. I unpocket my wallet to get my shopper’s card and debit card out. “Oh no, you didn’t!” the machine said as it called for backup. Cue waiting 3-4 minutes for the attendant to get to me.

    The machine asked the attendant if I was stealing and showed a replay of what it assumed must be me trying some Ocean’s 11 level of grand larceny. In the video? It was me getting my wallet out to pay.

    Absolutely no time was saved. Nothing was more convenient, and to top it off, I was once again accused of stealing by a bathroom scale with delusions of grandeur.

    I looked into it, but more for development purposes than installing it onto anything.

    Seems like it would be easy to develop for, but the ecosystem seems to be pretty locked down due to the permissions model. There’s some ability to jailbreak devices, but it’s not a huge list of supported models.

    For basic apps it’d be fine. But if I wanted to make custom applications for SMS, use bluetooth, make a new default dialer (e.g. to add SIP dialing), etc, it wouldn’t be possible since only OEMs can “bless” those. Even the next permission level down (Privileged) requires the apps to be signed by an authorized KaiStore.

    Since my goal at the time was to make a lightweight Meshtastic client, I just gave up since I wouldn’t have the necessary permissions to make it work.
