  • But what makes this AI model unique is that it’s lightweight enough to work efficiently on a CPU, with TechCrunch saying an Apple M2 chip can run it.

    An Apple M2 can run bigger, higher-precision models than this FWIW. More important than this is perhaps whether older CPUs can run it with acceptable performance.

    AI models are often criticized for taking too much energy to train and operate. But lightweight LLMs, such as BitNet b1.58 2B4T, could help us run AI models locally on less powerful hardware. This could reduce our dependence on massive data centers and even give people without access to the latest processors with built-in NPUs and the most powerful GPUs to use artificial intelligence.

    This is definitely relevant to my interests especially with NPU support for such models coming. Dirt cheap ARM-based PCs based on e.g. the RK3588 are shipping with small NPUs








  • Personally I’d go for as big a UPS as I could afford, but I serve some public-facing stuff from my homelab and I live in an area with outdated infrastructure and occasional ice storms. I currently have a small UPS and have been too tired/overwhelmed to set up automated shutdown yet. It’s not too hard though, I’ve done it before. And even without that in place, my small UPS has kept things going thru a bunch of <10 minute outages.



  • There isn’t a guide yet that I’ve found. I slowly & painfully assembled all the info and beat my head against the task until I had something working & stable.

    I’m currently building a comprehensive one, but due to circumstances beyond my control, it’s taking forever.

    I think civilization just hasn’t gotten there yet, but I suspect I’m not the only one working on this, so I bet the reverse proxy tunnel HOWTO situation will be way better in a year or two…

    FWIW I use nginx on the front end, and rathole for my tunnels - the latter is a very straightforward way to set up the tunnels.


  • Currently I have a bastion host running a hardened distro, which establishes a reverse proxy tunnel to its ssh port via my $4/mo VPS using rathole, an excellent reverse proxy utility I switched to from frp.

    I also maintain a Tor hidden service pointed at the bastion host’s ssh port and another on a different internal host. These are so that I can still get in if the bastion host, my VPS, or certain aspects of networking are down for some reason.

    Eventually I will implement port knocking / single packet authorization by deploying fwknop on some or all of these services to further enhance security.
