  • What about the performance info is wrong, may I ask?

    Sodium ion has far higher lab-tested cycle count than standard lithium ion/LiPo (3000-6000 cycles vs 300-500, max 1000 cycles) though in reality since sodium iron batteries are a chemistry that has been around for a few years instead of decades, real world is only 1000-3000 for the first generation while lithium iron phosphate still beats it with 3000-5000 cycles real-world, though that lithium chemistry is significantly more expensive, but indeed relevant to grid storage.

    Sodium ion batteries also have a much broader temperature range (-40 to 80C vs -20 to 60C where lithium cells are often capped at 45C to prevent damage).

    Charging times: sodium ion can charge between 2C and 3C while lithium ion is recommended to charge <1C. There are a ton of methods to get around that, but those would likely also apply to sodium ion

    It falls apart a bit more on density, voltage range, and discharge speed.

    Sodium ion can also handle 8C discharge rates, but not up to 10C like lithium, due to their higher internal resistance.

    The voltage swing is way larger (4V->1.5V) which isn't a huge "problem" per-se, but not convenient as all of the current BMS chips and inverters were made for the very low voltage swing of lithium, so you will need seperate ICs or only use 50% of the capacity.

    And of course the 30% less density or so.

    I don't think any of those are deal breakers for grid storage or a lot of "general use" when it will be much cheaper as it gets adopted and scaled.

    Very true that it is not optimal for EVs, but there are already Chinese Sodium-Ion EVs that perform quite well outside of the reduced capacity

  • I wish it was socially acceptable to interest-dump someone and for them to do the same to you.

    Just getting a 5-10 minute lecture deep into a topic that someone is passionate about is fun and educational! Much better than trying to make small talk or talk about the 3 common topics at your workplace (at mine it is local tv, energy spending/taxes, and cars), which is often sports. Then you get to learn about other people's interests too!

  • I peel carrots to give the peels to my dog because it is her favorite.

    I peel pumpkins/squash that aren't roasted, and potatoes if they will be fried (very different texture and they are unhealthy anyway), what other vegetables do people peel normally? I am coming up blank.

  • Jokes on us, investors and shareholders are already doing that.

  • It is funny because electric motors have nearly unlimited* torque depending on the kind. If you have thick enough power cables and winding conductors, you can just keep pushing it harder to get more torque.

    It is like the thing they are very good at, besides sound levels, double or triple the efficiency, low/no maintenance, simpler with less parts, no emissions, etc...

    Literally the only good thing about combustion engines are their fuel source energy density.

    I think the problem is that motorheads see the enshittification of the auto industry as a whole and just say it's because of electric motors because it happened right about the same time as EVs started coming out and try to push back on the wrong thing.

  • That only solves maybe one of the listen problems. Whatever instance you have, you still have to get and serve media to other viewers and instances. The only problem that this solves is potentially CSAM spam/moderation.

    Let's say it was a cell phone, it could handle maybe 2 concurrent transcoding streams before stalling out and people running into buffer times (which makes them leave).

    If every person had their own tiny, low powered servers, then you could have max like 5 concurrent transcodes on any instance in all of peertube for old laptop or desktop computers. Assuming an average of people have a 100/30Mbps connection (which is true in much of the world outside of major cities, or even lower), then that would be absolutely maxing out at 10 concurrent viewers if everyone is running AV1 compatible clients (which is not the case) and more like 6 concurrent viewers per video at h.264. Those estimates are at low bitrates also, so low quality, absolutely no slowdown from your ISP, and absolutely no other general home or work-from-home use. In reality it would be closer to 3-6 concurrent viewers per instance (not even per video)

    Still not even counting storage which is massive for anyone that creates more than a couple videos per year.

    My point is just that it is an extremely difficult and costly problem that is not as simple as "more federation" like in text and image-based social media because of the nature of video, the internet, and viral video culture. Remember, federation replicates all viewed and subscribed content on the instance (so the home instance has to serve the data and both instances have to store it)

  • Yep. I have posted on stack overflow exactly 3 times. One time it was marked as duplicate and referenced to something that was not even the same topic. One time I had too much detail and debugging done for the classic knowitalls to come make a smartass remark and was completely ignored. The final time I got one comment, addressed it, and that person was never heard from again lol.

  • What does you comment have to do with anything? He asked why delaware, I answered why delaware. Companies that are from europe still have to pay property taxes on american properties, worker-related taxes for their american workers, US health system taxes, income taxes for american declared income, etc... You don't just magically not have to have any sort of knowledge of any local laws when running an international business...

    Foreign companies must comply with local and state tax laws or risk facing tax compliance issues and be liable to penalties or even suspension of business operations.

  • The ton of US companies are registered in Delaware because it is the state for tax evasion.

  • Nice! Always good to convert something that is no longer supported.

    For future projects, I would also suggest using the SEEED studio Xiao series https://www.tinytronics.nl/index.php?route=product%2Fsearch&search=seeed+studio+xiao if you don't need a lot of IO, which is often the case with IOT stuff. I use it for everything HomeAssistant related.

    The esp32-c3 version for the cheapest with a nice antenna if you have to put the module near metal (my homemade doorbell uses this)

    The esp32-S3 model for more processing power (my VoiceAssistant satellite uses this)

    Esp32-c6 variant to replace the esp32-c3 for everything that you want to convert to Thread in the future (esphome is starting to have Thread support https://esphome.io/components/openthread/)

    Esp32 board are great, but the xiao series is so tiny that you never have to worry about them not fitting!

  • Doc Marten auality has apparently absolutely plummeted info the ground the past decade. Like, they only last a year or two now apparently before falling apart.

  • Probably has to do with tackling hard hitting issues like... Checks notes... Ensuring that vegetarian meat alternatives can't be called "steak", "burger", or "bacon". Ah yes.

    Couldn't have to do with multiple countries going full right wing + corporatization being in a race to the bottom lol.

  • I was not earning enough to donate with our renovation to try to fund, then I was also unemployed for a period, but now I have a new job that pays around 300€ more net per month, so I think I can start donating and still pay for the house and renovation.

    • FreeCAD
    • KiCAD
    • immich
    • gadgetbridge
    • codeberg
    • KDE
    • Krita

    Some projects that I use a lot don't want donations (jellyfin, antennapod, HomeAssistant, etc...) though

  • Just a few thoughts as to why it hasn't taken off:

    Video is multiple orders of magnitude more difficult and expensive to serve than text or even audio.

    • Your server needs a great upload speed which is not achievable for on-site home servers for most people in the world
    • Your server has to have at least one dedicated encoding GPU (no raspberry pis or Intel nucs if you want any meaningful traffic)
    • Your server has to have a ton of storage, especially if you allow 4k content to be uploaded, which while much cheaper than before, is still expensive. Here in the EU, reliable storage is around 300€/12TB for drives, which fills up very fast with 4k videos or if you try to store different resolutions to reduce transcoded loads.
    • Letting random people upload video onto your instance is significantly harder to moderate than text or photos. Like think of the CSAM spam that was on Lemmy when it started in taking many new users...
    • The power usage (and bill) of the server will also be much higher than without peertube because of constant transcoding

    The cost, both financial and server taxation-wise is simply too great for me, and many others to setup a peertube instance.

    Regardless of how easy it is for people to create on peertube, someone has to bear the cost of hosting it. That is cheap-ish for Lemmy or mastodon, but there is a reason YouTube was a loss leader for a long time for google, and many streaming services restrict 4k video.

    That isn't even getting into compensation for the content makers.

  • I wish I could use unattended-upgrade.

    It literally restarts my server even when I disable the option, leaving it hung if the USB boot key isn't in there.

    I had to stop using it, so now I just manually upgrade because that doesn't auto-restart without my permission...

  • Yes, but I am also of the opinion that not one single acronym should be used without at least once in the section saying what the acronym is. Many many programing docs with say what am acronym is exactly once, somewhere in the docs, and then never again.

    Also, if there are more complex concepts that they use that they don't explain, a link to a good explanation of what it is (so one doesn't have to sift through mountains of crap to find out what the hell it does). Archwiki docs do this very well. Every page is literally full of links so you can almost always brush up on the concepts if you are unfamiliar.

    There seem to be 10 extremely low quality, badly written, low effort docs for every 1 good documentation center out there. It is hard to RTFM when the manual skips 90% of the library and gives an auto-generated api reference with no or cryptic explanations on parameters, for example.

  • Maybe european car companies should just do better. I wonder if they ever thought of that?

    Just because they are european, doesn't mean they are a company we should buy from and support. Nestle is European and is a baby murdering, child trafficking, chocolate slave trade company that kills and sickens thousands of people a year by illegally stealing water from them. Unilever is also pretty shit, spotify is just about the worst streaming service, not to mention the pharmaceutical companies...

  • Nope, Toyota is going HARD on subscriptions for literally every single feature. More and more every year. Remote start (Mazda also does this), charging you an upfront cost for hands-free driving, then telling you after that you have to pay 25€ to use it, soon seat heating and brakes will probably be locked behind a subscription after paying 50k for the car.

  • also VW with it's bad everything in the ID line besides looks i guess and still charges 41-58k€. It is insane for something with terrible mileage (and an estimation that just plain lies), laggy as shit entertainment system that has taken up to 15 minutes to connect to android auto (2020 passat takes <3 seconds on the same phone) and is very buggy and sometimes needs a full car restart to show the maps app, horrible quality backup camera (my 2015 Nissan Altima had a 10x better quality camera) that has to be cleaned literally daily because they placed it so badly, terrible volume control, and no seat adjustment, and still tracks your every move.

  • While the lack of laughter can be from depression or stress (the podcasts I used to die laughing from only get an actual laugh out loud moment every once in a while now), I feel like most story-based video games that do humor try too hard nowadays and it doesn't land (like outer worlds)

    Most of my laughter in video games, personally has been from interacting with other people. Valheim, Helldivers 2, REPO, overcooked, stardew valley, etc...

    Probably the last single player game I laughed with was A Hat in Time or something.
