    Hey, I'm in a similar situation, down to the lack of a balcony. I have a whole-home, per circuit power monitor, and I think your assumptions about where you're consuming energy are unlikely to be correct:

    • one of my stovetop burners is 2kW. This is a lot of power, but almost no energy since it is rarely on more than 30min/day or at more than half power.
    • you're super over-concerned about the dishwasher. It can draw 2kW, but again, that's for only 10min of the drying phase of a 3 hour cycle. Please use the dishwasher, you will certainly save money over sending hot water down the drain
    • Dryer is likely to be a high energy consumer. It is for me. It basically sucks down the rated power the whole time it is running. I believe there are government rebates for heat pump driers available.
    • The internet's numbers on the washing machine are completely bogus, and the duty cycle is low anyway. It may be worth getting a more efficient machine if it is very old.
    • How often is the compter on? Mine is on 24/7 so I am concerned about power use there, but if you turn it on/off as you use it, don't worry about it.
    • Most fridges run their compressor on/off at a regular interval. It may be rated for 540W, but you need to listen for it to click on/off to tell exactly how much it draws.
    • TV -- nothing to worry about here except the idle current. My TV drew 20W turned off when I had it configured to turn on from the phone app.

    The common theme here is that the power use doesn't matter -- the energy draw, which is power multiplied by time on, is most relevant for most rate plans on most electric bills. Here's what I'd suggest:

    1. Cut down on hot water use. You don't mention it, but this is my #2 power draw, after heating/cooling. Make sure you have a modern showerhead & use the dishwasher instead of hand washing.
    2. Eliminate incandescent bulbs.
    3. Track down vampire loads. A outlet power meter is useful for this. But I've noticed many loads draw relatively high power after they are plugged in, so wait 15 minutes to see what the true idle power is.
    4. More modern appliances are generally more energy-efficient. I believe there are rebates right now for thing like heat pump dryers and heat pump water heaters.

    Plastic bottle holders are probably great! I like a more classic aesthetic so I've never had one, but this is one place where you just pick something you think looks nice. I over-research my buying decisions too, but this one should be easy.

    so I would think that it wouldn't get beat up much if at all.

    I'm just thinking about the layer line weaknesses with 3d prints, and how the bike gets jostled while going over potholes. Just my opinion, I've never tried printing anything for my bike, although I've been both printing & biking for a long time.

    Is there any specific reason to go with Kryptonite over any other brand?

    Other reputable brands are fine too. It's hard to tell whether a u-lock is good or bad without destructively testing it, so it's probably worth getting one that's well reviewed and from a company with a reputation for quality (not Masterlock, not "BIKEGOOD" on amazon)

    anyone had any recommendations for 3D printable designs for the bottle holder.

    I'd be surprised if there was a good design here. This situation requires high strength on all 3 axes and impact resistance. I don't really think it's possible to do cheaper and better than the classic bent-wire design.

    That makes a ton of sense! My personal experience to clarify where I'm coming from:

    I have the system on a schedule to clean half the house each day, but including the kitchen each day. I have a small place, so it cleans the furthest room each night, but the other rooms are cleaned on an alternating basis during the day. After its daily clean on Friday, it goes to the trash can for me to empty it & replace the mop/cleaning fluid.

    This has totally eliminated manual vacuuming for me, except for every month or so for the most heavily trafficked rug. The floors are always spotless with nearly no effort on my part. But the vendor's app hasn't been much help for this, and this heavy automation only works because I was able to do it from Home Assistant.

    But what you don't get is:

    • efficient cleaning, where each spot is only covered once. this is important since the vaccum is loud and I'd like to minimize the time spent
    • scheduled cleaning
    • room mapping, so you can tell it to specifically go clean only the dirty rooms

    None of these features require an internet connection or a camera, and the $200 version at target also won't have them, but they are extremely useful.

    From their statement:

    This investigation also identified a credential stuffing event, in which a third party attempted to use email addresses and passwords to try to gain access to Ecovacs’ customer accounts. There were significantly more attempts to log-in than the average daily amount, by a factor of 90:1. These all from the same IP address, which was identified as coming from both an unusual device, and an unusual location. This IP address was
    immediately blocked.

    A single person was able to make 90x the number of login attempts that every other user in their system was making combined? I appreciate their transparency, but this doesn't look good.

    I didn't realize we were using drones without human input for war?

    It's a spectrum. Is a Javelin missile a drone without human input? Once it is launched, it tracks its target visually (more-or-less) without any human input. Technology here is definitely progressing for them to become more capable of being able to allow weapons to select their own targets given certain parameters.

    AI systems could, for instance, simulate different tactical ... The Chinese military

    Yeah this part is just fear-mongering BS. There's no substitute for human judgement, and every time I've seen breakthrough claims like this outside of the military context it's been just marginally passable garbage in contrived situations. It's in everyone involved interest to pretend that it's more significant than it actually is.

    And in Gaza, Israel has fielded thousands of drones connected to AI algorithms, helping Israeli troops navigate the territory’s urban canyons.

    Reading between the lines here (and doing a bit more background reading) these can't hurt anyone. They're just for mapping and reconnaissance, which is pretty much the lowest-risk application of this technology.

    As a software engineer who also works on OSS, I wouldn't dream of criticizing the engineers/doc writers/translators in the community. The exact opposite actually: people second-guessing improvements, even if they are obviously improvements for 95% of the userbase, is draining for the developer and not fun at all.

    Even something as simple as the new smart dimension tool has criticism. And for a long time, people have been dismissing the toponaming issues as something you just need to "get good" at, and not major flaw in the program.

    There's a large group of FreeCAD users that are resistant to any change at all, and who consider FreeCAD's quirks features. As FreeCAD is gaining popularity, this group is getting diluted, but in the meanwhile you can jump right to good defaults by using Ondsel-ES.

    What exactly does the system do on a positive identification of a phone use in the car? Pull the vehicle over? Stop it? Auto send a rate increase to your insurance?

    This is already solved by existing partial self-driving technologies: nudge the wheel a bit to test the driver's attention, and if they don't respond in time, slow the vehicle down and pull over. As a bonus, this would save the lives of drivers who are having a medical emergency as well.

    How in the HELL do you control for false positives? The image detection software i've seen is impressive. It's not, "risk my life or my future" impressive.

    Test the driver's attention subtly.

    How many people are you willing to punish? Shall we include all distracted driving? Single mother who took her eyes off the road to give her kid a bottle? Parent rushing to their child while on the phone as they're having some sort of major incident?

    I think I've addressed this above but I want to note that driving is the only place where this cavalier attitude to safety exists. I may just have been lucky, but I've never been in any job site or warehouse where people operating heavy machinery gave it anything but their full attention. But cars are styled like toys, not heavy machinery, and driver licensing in this country is a complete joke, so people don't take them seriously like they should.

    What you're describing here is known as a "normalization of deviance". This is a classic human fallacy. Our attitudes to driving would not pass muster anywhere that safety is taken seriously.

    How much money are you willing to force everyone to spend?

    Even if it didn't fit inside existing systems, I'd expect the overall cost of this kind of system to be < $50.

    How much are you willing to punish drivers who break or mess with the system?

    We already have this mostly figured out with our emissions systems. Something like 2-5% insist on bypassing regulations, but having the vast majority of people leaving things alone is a huge improvement.

    There's no reason this can't be done fully locally in the car.

    Driving a multi-ton machine that can easily kill others means that you have restrictions placed upon you. This has always been part of the contract you make with the state to be allowed to drive a car. For example, you can be required to have blood drawn for testing if you are suspected of drunk driving, something that is infinitely more invasive.

    Per paper bag? that seems absolutely insane, a paper bag weighs < 100g by itself. Especially when plastic bags are essentially carbon capture technology when they are properly disposed of in a landfill.

    The cost of improper disposal is obviously high, but I'm not convinced that plastic bag bans at grocery stores are effective at all & not just performative. After all, you always bring plastic grocery bags home because that's where your fridge is.

    I would be happy to see plastic bans in things like takeout food, which anecdotally, actually do make up the bulk of litter.

    Nanogenerators produce picowatts to nanowatts. A picowatt is 1 billion times less than a milliwatt. A nanowatt is 1 million times less than a milliwatt. I don't think anyone can truly intuitively understand how small these numbers are.

    Nanogenerators never produce anything anywhere close to the magnitude necessary to power macro-scale devices. Not even when many are used together (if they can, IDK since this is not my area of expertise).
