    Running qwen3.6 27b through llama.cpp.

    It’s about as capable as sonnet 3.5.

    I use it for light scripting, but real coding is done by cloud models.

    I’m also using it as the brain for my Hermes agent. It sends me digests of news, subreddits, chats that I’d like to read but don’t have time for. It does a great job researching things on the web for me, too.


  • I don’t miss windows, but I do miss sitting in the same era computer labs with either the university’s own flavor of red hat, or SPARCstations.

    The internet was a lot more fun 30 years ago. I guess partly because it felt like magic, and after a degree and some decades in the industry the illusion is gone.

    Also, it used to be about sharing pictures of your cat or listing your favourite books. Now everyone is trying to either sell you something or source everything about you to be able to sell you something with more accuracy.






  • There’s an infamous usenet-thread with Torvalds and Tanenbaum arguing over monolithic vs microkernel design. I microkernel is cleaner from a separation standpoint, but that also introduces hurdles and overhead.

    Linux is popular because the hardware support is pretty great. There’s few laptop/BSD combinations that work well with sleep/suspend/wifi, while just about any laptop will have everything working with a recent Linux kernel.


  • Yeah, I mean apocalypse scenario is not my main goal. But it’s nice to have a contingency plan if shit would hit the fan.

    This is my second season with the caravan, I had an apocalypse sailboat before that. I put 2x100W on it for the first season, added another 2x100W this season while going from 160Ah lead-acid to 300Ah Lithium. It’s a night and day difference there already.

    I’m plugged in most of the time, either for air conditioning or heating - the Mrs wants her comfort. There’s a three-way absorption fridge (220V, 12V or gas) that draws like 110W. I can still be unplugged for three nights or so with that running; which makes long distances or overnight ferries possible without ruining food.

    And if we want to stay somewhere without shore power we can flip the absorption fridge to gas and be cooking with gas as well. The compressor fridge chest that sips 30W usually sits in under the awning in front anyway.






  • I don’t power all of it at once, and not direcly off of solar. I could maybe fit another 200W worth of panel on that roof, but for 4000W I’d need seven caravan roofs. That battery is the buffer and it’s a beast. At 300Ah I have 4kWh to pull at 1C.

    The fridge sips a nice 30W. Panels put in ~2kWh on a sunny day. So thats a 1.7kWh surplus for running heavy loads - enough to max out that inverter for an hour a day. That’s plenty for microwaving or pumping water.


  • If power is down for good, then getting water is the main priority. If the pumpa don’t run the water tower is losing pressure fast. I have 40 litres jugged up in the basement at all times for the first few days.

    When that dries out my neighbour has a well that we’ve hooked up to five properties. Mostly for gardening, but it is potable. The pump needs power, though, so I’d pull an extension cord over to my caravan.

    My caravan has 400W of solar, 300Ah LiFePO4 and a 1.5kW inverter. Also a meshtastic node with an antenna on the roof. That’ll keep the food cold, and laptops charged. It can run a microwave or hotplate, too. I’ve got 20kg of propane if I need to conserve power.






  • Pros:

    • I have the source. I don’t have to wait for fixes or features. I just do it myself and send a patch or PR upstream.
    • I can run it on just about anything, and well.
    • Sane defaults and handling of user permissions - by design
    • Modern filesystems that don’t silently rot your data
    • Full control
    • No forced updates
    • No telemetry

    Cons:

    • Not a priority for pro applications
    • Not fully POSIX compliant

    I haven’t used windows in almost 30 years, but… I probably missed some games at first that DOSBox couldn’t run well (yet). Not a problem any more.
