  • I think there’s a bias in the US against this sort of thing that doesn’t exist (or not to the same extent) in Europe due to the age of the cities/buildings.

    In the US, a building from the 1700s is a historic artifact to be cherished, while in parts of Europe a building from the 1500s is just the local pub.

    So, the US is often hesitant to modify these old buildings, but Europe seems to have more of a perspective of “it’s a building, not a museum, let’s give it new life by modifying it.”

    This is just from the perspective of me, from the US — and I think these old/new buildings are really neat!






  • My headcanon for The Matrix’s “humans are batteries” is that it’s the machines’ perverse interpretation of this — killing the humans is off the table, and for whatever reason letting them live with no purpose to serve the machines is also disallowed. But giving their lives “meaning” in the form of a shitty (and thermodynamically dubious) “battery” somehow satisfies the rules.

    It’s a very big stretch, I’ll admit…





  • That’s how I started using Linux — big book with CD, I think it was “RedHat Linux Secrets 5.4” or something. 2.0 or 2.2 kernel.

    Honestly, it was fantastic. And almost all of it is still relevant today. (Some of the stuff on xfree86 and the chap/pap stuff not so much.)

    But it gave a really solid (IMHO) intro to a Linux/*NIX system, a solid overview of coreutils, etc. And while LILO has been long replaced, and afaik /sys didn’t exist at the time, it formed a good foundation.

    I’ll refrain from commenting on any init system changes that have taken place since then.




  • We tend to use between 3kWh (vacation/idle power consumption) and around 8kWh per day. If we switched to electric stove, water heater, and heat pump, and add a hot tub, that’d increase substantially. But if we added solar (on our long Todo list…), the battery in the article (60kWh) would probably be able to handle all our storage needs, and it’d fit in he garage (bonus of it can be placed outside/under a deck!). I live in a major city, but I would absolutely love to effectively be off grid.

    Exciting stuff — it seems these are touted as being extremely robust/safe, which is of course important for me if it’s going to be in/near our house. Storage density not a huge concern, but price is somewhat important — let’s hope this sort of thing ticks all the boxes.




  • It can be daunting to get into the hobby, there are a ton of niches.

    To start: where are you? I’m in the USA, so that’s where my experience is.

    License: required to transmit on the ham bands; you can listen without a license.

    Range: are you looking to talk to people in your city/region? If so, a cheap “walkie-talkie” style (called “HT” in the biz — best avoid “walkie-talkie”) is a good place to start. These VHF/UHF (very/ultra high frequency) radios are affordable — something from Baofeng(~$30) or similar will work just fine, though they are often looked down on (I have one — for the price, it’s great). You will have the most luck if there is an active ham scene in your area, in large part because they may have a repeater, which can greatly extend your range. Many regions will have scheduled “nets” where you just go around and chat.

    If you’re looking for the ability to chat with folks on the other side of the world, you’ll want to look into HF (high frequency). This is much lower frequency, thus longer wavelength, than the handheld VHF/UHF HTs. So…the antennas take up a lot of space. Mine is 52 feet long, in the attic. And the radios are much more expensive (more like $1k new). ICOM 7300, Yaesu FT710 are popular entry level units (but you also need power supply, cables, and antenna).

    That said: if you just want to listen to HF, the antenna doesn’t matter as much at all, and you can use an SDR (RTL-SDR probably works?) for listening. You can probably also find a used shortwave radio that covers some of the HF ham bands.





  • I think you need to include energy cost in the preparation stage. Bread requires a hot oven, which is a real amount of electricity — it’s close to $0.40/kWh where I live. From this link it says that a bread maker uses only .36kWh, but an electric oven would be more like 1.6kWh. So bakita single loaf of bread, you end up with a not insubstantial fraction of the total cost going to heating the oven.

    Of course, many bull foods require heat, so it gets a little sticky this way. Oats/oatmeal probably wins out here, as you can just soak them overnight.
