  • I have to admit I’m not entirely convinced these requests are coming from a compiler…

    Is it possible for you to virtualize an non-networked system with your GPU passed through? That seems like the best option IMO. Next best thing would be to set up an airgapped machine just for this, but not everyone has a 2nd machine.

    Personally when I was trying out local LLMs I used a virtual machine, mainly due to the known code execution vulnerability related to Tensorflow model data being saved in python’s Pickle format. I believe the recommended save method changed twice since those days though.

    With the Firefox stuff I’m assuming you’ve also checked their enterprise config options too (which are admittedly difficult to find and piece together online), so not too sure what else you could do except aside from continuing to block them. Librewolf however provides documentation on how to disable the extra requests sent from their browser in their FAQ, and covers some preferences on the subsequent page linked at the bottom




  • AFAIK on Windows the physical disk containing the partition needs to be marked offline in Disk Management, and the disk or a partition given exclusively to VirtualBox running as administrator, otherwise access is limited to read-only

    I would suggest checking some other sources as well, just in case this has changed over the years. If you do successfully pass the physical partition into VirtualBox read-write, you might need to set up a virtual disk with grub to boot into your physical Linux partition



  • I’m rooted to…

    • backup & restore my apps as I please (as well as scheduled backups to my SD card)
    • BMS control to keep my battery in good health
    • Automation app for automating stuff (like Tasker)
    • revoking typically unrevokable permissions from system and Google apps
    • To actually feel like I own my device.

    If I wanted a heavily curated (and somewhat locked down) experience, I’d be in the Apple ecosystem - don’t know why Google thinks it’s a great idea to force this ideology onto practically all Android users…

    Similar situation with that additional warning for sideloading apps - there’s already two warnings and Play Protect typically uninstalls these apps anyway, without the user’s consent - in one case deleting KDE Connect from users’ devices if installed with F-Droid

    Uhh I definitely went off on a tangent, oops.


  • A while back I made a Lolin32-based weather station that lasts for around 60 days on a single disposable vape battery.

    It wakes up every 15 mins, and while it’s connecting to WiFi it retrieves the AM2302 sensor readings. As soon as they’re transmitted it goes back to sleep.

    I wish there was a more power efficient alternative though, like whatever is being used in those BLE LYWSD03MMC sensors that last for around 3-6 months on a cr2032 whilst also having a display built in





  • To answer the direct question - no

    I do have some thoughts on moving away from the Pi though - warning, heavy personal bias ahead

    If you’re looking at moving away from the Pi I would just suggest a low power x86 box, like a Nuc or some Intel N100 low-power tiny PC.

    There is a caveat though - it looks like the OctoPi project only provides OS builds for the Pi, so if you change systems it looks like you’ll need to install OctoPrint manually, and port over your config somehow.

    On ebay you can get second-hand NUCs, 6th gen and up, for practically peanuts. The cheaper quad core celeron nucs (i.e. J3455) are roughly equivalent to the 3rd and 4th gen dual-core i5s (3777u, 3230m etc) performance wise, but have an updated QuickSync encoder and support accelerated 4K video encoding/playback, handy if you want to capture timelapses of your prints or just view them live. They also consume 1/3rd of the power at around 10 watts under the same workload.

    ARM support for other vendors can be pretty flaky, sometimes even non existent. While you could pick an Orange Pi, and go with a modern community-supported distro like Armbian, it isn’t a turnkey experience like the Pi. There is much less documentation, and still some very early boards floating around with hardware defects and overheating issues (posing a fire risk in the worst case, the OPi Zero being the most egregious - literally melting the optional enclosure and killing the NIC). Some research before buying will let you know most of what you need to know - check around the forums for any common issues and dealbreakers, as well as the manufacturer’s site to get an idea of available support.

    If you want to get an idea of the alternatives you could check out Jeff Geerling’s youtube channel, he covers the Pi and occasionally videos on other alternatives, as well as issues he’s had with them and support. I’ll try and link some below…

    Check the comments on that one for a quick synopsis, as the video is quite long…

    This video pretty much just echoes my current perspective


  • To combine a bunch of explanations I’ve seen in the comments here:

    A bourgeois philanthropist game show producer who dabbles in poverty porn.

    That said, I do occasionally burn time watching some of his videos, however some of the content (especially the more recent game show ones which feel a bit like toying with people) rub me the wrong way.

    I have no idea if his philanthropy efforts are genuine or not - he’s barely visible in those videos (he has another individual hosting those videos) although I do appreciate the efforts they appear to go to when assisting communities desperately in need, and careful implementation of solutions that are sustainable, and can actually be maintained and fixed with local knowledge.

    I’ve seen way too many “gimmicky” charity contributions by other organizations that become worthless as soon as they break because nobody fixes them, as well as other solutions that seemingly make sense from a western cultural lens but aren’t really understood by the local people… worst one being a “merry-go-round” water pump mechanism where senior locals are forced to “play” just to pump water for survival. It was originally intended as a kids toy, but they of course don’t have any attachment to such a foreign device, thus don’t use it.

    Ehhh apologies for the mini rant there 😅
