98% of hydrogen is currently made from fossil fuels.

While it's possible to make hydrogen from renewable electricity, you immediately lose at least 60% of your energy in the electricity to chemical to electricity conversion steps. For comparison, batteries only lose 5-10% in the round trip charging.

Hydrogen really only makes sense in applications where batteries can't be used, or efficiency is not relevant. So many companies have publicly announced their new hydrogen vehicles, then quietly stopped using them and started using battery electric vehicles instead.

Hydrogen just costs too much, and the hard limit of chemical efficiency means it will never be cheaper than batteries.

    Ritalin long acting.

    The default (short acting) Ritalin worked, but it was like a rollercoaster. When it worked, it was amazing. As it started to wear off a few hours later, I couldn't even get out of bed.
    I was on the minimum dose. I tried cutting the pills in half and taking the second half later in the day, but that just gave me 2 cycles per day instead of 1.

    The long acting is much milder, but the wearing off effect is also milder. I'm only 1 up from the minimum dose and I'm quite happy with it. I just can't schedule anything important between 4pm and 8pm.

    You're not alone. I dropped out of university partly because I was making a Minecraft mod instead of studying. I knew study was important and I knew the tasks were interesting, I just couldn't stop.

    Something that forces a pause (router schedule) can help initiate a task change, but that doesn't stop you thinking about what you were just doing. Sometimes you just don't have the executive function to be able to change task.

    I never found a good solution until I had an effective medication.
    I'm certainly not fixed now, but the same strategies are a little more effective since. Coffee (and other stimulants) can assist too, just don't rely on them as a miracle cure.

    With complete transparency, a corrupt government can execute any group they want (disabled, homosexual, black, immigrant, etc).

    If everyone was completely transparent about everything, a corrupt government would not be able to form. Unfortunately there are people without empathy who will hide their actions, and use other people's information against them.

    I can't force a government to be completely transparent, but I can save my own life by not disclosing certain information about myself to them.

    I don't hide my bank account and password because I've done something wrong or I'm afraid that people will see what I've spent money on. I hide my bank account and password because I'm afraid that someone will take all of my money, then I'll starve to death.

    There are many things that should be public: laws, standards, political donations.

    Some things are beneficial when public, but are considered acceptable to be private: source code, recipes, political opinions, criminal history.

    Some things can cause significant harm if not kept private: passwords, home address, government issued id, Jewish heritage during WW2.

    "I need privacy, not because my actions are questionable, but because your judgement and intentions are."

    I've heard of Australian bushfires traveling close to 100km/h (60mph) with a strong wind.

    What's even worse is if the flame front is diagonal to your path of travel. The flames might be going 50km/h, but if they're coming at you at 60%, then you have to be going at least 100km/h to outrun them.

    Fires don't need to follow roads. If a fire is traveling perpendicular to the only road you have, you can't drive away from it.

    cross-posted from: https://aussie.zone/post/27301455

    I took my new (to me) electric motorcycle out with friends for the first time.

    I calculated from my previous solo trips that the motorcycle had a range of about 120km (75mi). My friends were more experienced than me, and they picked the route. I had told them that I was only comfortable riding 100km, but I guess that didn't mean much. If I had pressed for details about the route instead of trying to fit in, I would have discovered that the round trip was 140km before we left.

    The motorcycle performed beautifully until it shut off after about 120km. Still 20km from civilisation.

    What I learned that day is that the average person is far kinder than social media will lead you to believe. I was near the top of the hill, so I decided to push to the top and coast most of the way home. I think around 6 people stopped to help push on the steep section of the hill (one at a time), and I lost count of the number of other people who stopped to check on me on the flat sections. I'm guessing over 20. I was actually thinking of writing a sign that said "I'm fine, don't help me" just so I could make faster progress.

    It was a pretty warm day and the motorcycle is about 300kg (650lb), so I was happy to take water from 4 different people along the way.

    Eventually someone with a trailer stopped and asked if I wanted to put the motorcycle on the trailer and get a ride home. I don't think I've ever accepted anything faster. It cost me a bottle of high quality whiskey, but it was still much cheaper than calling for roadside assistance.

    In summary, it was partly my fault for not pushing for details, and partly my fault for not checking the distance travelled as we went. I'd love to blame the motorcycle for cutting out with 2/5 bars remaining, but I really did know the maximum range. It's also a really cheap motorcycle with almost no thought or effort in its design. It even has a chain guard for a hub motor (no chains anywhere).

    I still love the motorcycle, will still only ride electric, and will probably ride with those friends again; but next time I'm checking the distance first.

    A great view of the rolling hills into the distance with no houses to be seen

    The motorcycle used. Braaap Moto E 8000W

    TL;DR
    Rode electric motorcycle further than its max range. Humans are much more caring than you'd expect. Got home exhausted, but proud of humanity.

    Dual sim (aussie.zone)

    Do any combination of phones and OSes have support for desktop Linux apps, VoLTE, and dual-SIM?

    I want to get away from Google. My current phone (Nokia G42) doesn't seem to have support for any OS except Android. My ideal setup would be a Fairphone 5 with Ubuntu Touch, but that doesn't seem to support dual-SIM.

     

    I've had an old laptop running Home Assistant for quite a while. I've recently started getting into docker. I'm part way through setting up a NAS and want to check if I'm doing anything really stupid.

    My ideas so far:

    • Samba sharing a host folder on the local network
    • Rsync for regular backups to a separate host folder
    • WireGuard to connect directly to an offsite laptop with the same setup
    • Syncthing for realtime synchronisation and temporary file versioning
    • Home Assistant for rsync backup monitoring

    Are there any issues with this setup, and is there anything else I should consider?

    Request: I'm looking for something with high reliability rather than high speed. It needs to support 30+ devices.

    Additional information: My house is about 30m (100ft) long, and the internet comes in by ethernet at one end of it. I'm happy to use a Wi-Fi extender if needed.

    Context: I've been having issues with both my current and previous routers. Devices are randomly unable to communicate over the network for several seconds at a time. Both ethernet and Wi-Fi are affected.
    I live in Australia, so even the slowest router should be more than fast enough.
    I have a large number of automated devices that need to stay connected at all times - even 5 second network dropouts are difficult to deal with. Internet dropouts are handled gracefully.

    Any suggestions are gratefully received.

    Update (8 months later):
    My existing routers are ASUS RT-AX53U. Updating the firmware had no effect.
    Replacing the firmware with OpenWRT fixed all of the issues.
    I've also run an Ethernet cable between them, but it was working perfectly as a Wi-Fi mesh/extender anyway.

    A community for users of the wholesale electricity provider Amber to discuss strategies for optimising energy use, and request help with understanding how energy bills work with wholesale electricity.

    There are several Amber groups on Facebook and Discord, but nothing that is publicly accessible or viewable without an account.

    EDIT: The name is still under consideration. Suggestions for a name to encompass all users of wholesale electricity prices are appreciated. I'm currently leaning toward "Wholesale Energy Australia".
