  • Dang, that thing is the bees knees!

    Would make more sense to replace just the batteries rather than the whole unit IMO. Looks like it takes standard 12v 7Ah sealed lead acid batteries, so should be doable for under $120 (if you buy them individually and use the existing battery harness)

    I have three other UPSes, but none of them are as good as yours lol:

    • APC SUA1500RM2U - was a great online rackmount unit, stopped using this a few years back because of its tendency to overcharge batteries without a charge controller ADC calibration mod. It wrecked my last battery pack bad 😭 plan to convert it to LiFePo4 and put it back into service 🤞
    • Zigor Ebro - cheap and cheerful line-interactive UPS for the modem, network switch and CCTV cameras. Switchover time is pretty much instantaneous, worth every cent paid and has kept my network up through many outages
    • Cyberpower UT650 - A temporary offline UPS to hold the server gear specifically until I get the APC back in service. Honestly not worth the cheap price, the switchover delay is long enough to shut off anything that’s not a server PSU with massive bulk capacitors

    Edit: fix bullet list formatting




  • Flash drive hidden under the carpet and connected via a USB extension, holding the decryption keys - threat model is a robber making off with the hard drives and gear, where the data just needs to be useless or inaccessible to others.

    There’s a script in the initramfs which looks for the flash drive, and passes the decryption key on it to cryptsetup, which then kicks off the rest of the boot mounting the filesystems underneath the luks

    I could technically remove the flash drive after boot as the system is on a UPS, but I like the ability to reboot remotely without too much hassle.

    What I’d like to do in future would be to implement something more robust with a hardware device requiring 2FA. I’m not familiar with low level hardware security at all though, so the current setup will do fine for the time being!



  • If MIT AppInventor is still kicking around, you should be able to use it for this… although sadly you won’t have access to the source code since it’s a Scratch-like way to create apps.

    By default the Android voice assistant uses Google tech AFAIK, if you’re after a truly source-available solution then there’s ”Futo voice input" to handle STT, and “RHVoice” to handle TTS - though these would still need a HTTP API bridge to do what you want








  • Free google play credit, I usually get an email every year for it

    But I do pay for Plex, despite Jellyfin being a thing. If I like something and it’s worth it to me personally, why not 🤷‍♂️… but you will never find me defending their kinda crappy decisions like the new Discover feature, removal of “All Songs” from the plex apps in favor of moving people to Plexamp, removing the Gallery sync a few years ago etc.

    Some people want their software to be 100% FOSS all-eyes-on-the-codebase, others just do a balancing act based on their personal values.

    I value my software to be “transparent enough” in how it operates, “just work”, and hackable to some extent - if I really wanted to I can swap out the ffmpeg binary that Plex uses for transcoding to something else (doesn’t remove the Plex Pass limitation for those curious), I can hook into the server API to change ambient lighting colour based on the cover/background of whatever media is playing, I can create speakers running a Linux board to cast Plex media to, etc. But once that hackable ship sails, then I will look to FOSS alternatives.

    For Niagara, everything “just worked”. No noticeable bugs, fast search, consistent feel and design, useful contextual info (e.g. next calendar event shows under the clock), and gestures that made sense for its overall UX. Using it felt less like you were using a “launcher”. The yearly sub was cheap enough that I wouldn’t mind covering for it if I didn’t get credits, and having a single person working on software usually comes with a high level of attention to detail (particularly in performance and UX) but it does have the downside that the experience may be more opinionated and closed compared to if it was a community-driven FOSS project instead IMO.

    Alas, google didn’t send credits this year, Niagara made less sense for value/worth-it compared to Kvaesitso, so I abandoned it.

    For me, Kvaesitso does everything in a slightly different, much more customizable way, and being FOSS was one of the things that made it particularly attractive as a replacement





  • Edit: sorry, I may have misunderstood your post - free email != email masking.

    My original post below…


    Curious why you consider email address masking services as for those with “drastic anonymity” requirements?

    I personally don’t think so: they are pretty much just a digital P.O. box, and are typically not anonymous in any way (subpoena/court order to the provider). They are built-in to Firefox too, it will automatically create new ones OOTB as you sign up on websites, if you click the autofill.

    They are however IMO one effective tool out of many to restrict the ability of data brokers and hacking groups (aggregated breach datasets) alike from making money from your online presence without your consent.

    In almost all cases this data is freely searchable for law enforcement and private investigators, allowing them to avoid going through the legal system to investigate and possibly detain you for things you’re not guilty of
