  • When I was a youth, we used to go to Safeway and get donuts or "Mojo's" (wedge fries) at the bakery, then munch them while walking through the store so that they were gone by the time we got to the till to buy our cans of pop.

    One of those unforgettable moments from those years was when we were finally called out by a security guy, something very casual like "you boys are gonna pay for those donuts up front, right?" and Chris who was "that guy" in our crew, bounced his donut off the mall cop's head and ran like his life depended on it

  • I've seen conversion kits for old trucks under $10k. So there's your answer.

    Unfortunately said kits are often lacking in range unless you're willing to fill your truck box with batteries, because you can't really retrofit a "skateboard" style battery.

    I literally want that skateboard with seats and a steering wheel. Hell, give me a diesel burning heater and a washer fluid bulb I have to stomp on like I have in my old truck, I'm not picky

  • People are genuinely unimpressed with the high prices and low range numbers on what are supposed to be the next generation of vehicles. Volume and tech advancement were supposed to make them cheap and practical, but all that's gone up is the price.

    Especially with talk of banning the sale of gas vehicles in the fairly near future, they are going to have to do a lot better than this or a lot of people are just going to end up without any vehicle at all.

    Myself living in a rural, cold climate, 200km from any major center, nobody has made any practical vehicle for me yet. I even already own an EV, but it's really just a powerful golf cart. Once it gets much below freezing, I'm lucky to make it to a neighbour's place and back.

  • That's a bit much, isn't it? It's a brand new weird-ass truck, people are going to talk about it. And the article isn't exactly celebrating it.

    If this article was about a new car from another brand, would you complain about it? I thought we wanted more content on this platform. Or we could just stick to memes I guess...

  • Radiant heat transfer in the real world often appears quite odd in its behaviour despite being seemingly simple. I learned quite a bit about it when I decided to implement radiant ceilings in my home.

    Yes, the panel radiates the same amount regardless of where it's pointing. However, other rays are incident on it from other surfaces that deliver heat back to the surface. Thus the point of a selective emitter that emits more than it absorbs. Likewise solar thermal panels are optimally made from selective absorbers, but IRL flat black paints are so much cheaper that it's not worth it.

    So thermal comfort often is a result of radiant balance. Your 20° clothing radiates to the walls - the 20° walls radiate to you - there is no net loss of heat, and you are warm.

    Step out under the dry, cloudless prairie sky at night, you radiate into the infinite blackness of space. Nothing radiates back. You cool off rapidly. It's not so much that the heat needs to be dumped into space, but that space offers no heat in return.

    Seriously it's pretty neat to point my thermal scanner at the night sky and see it read -INF. The night sky is an effectively unlimited radiant sink.

  • My white building is currently covered by spiders and crud. Luckily it'll soon be cleaned spotless by the first blizzard of the season, which would also polish off this paint.

    However this is really just some science YouTubers replicating an experiment, far from a commercial product. It's just for interest. I like Tech Ingredients, they try to do fairly rigorous work on the border of pure and applied science.

  • It's a bit like gravity. We have some good theories, but that's about it.

    No! That's the point I'm trying to make! Gravity and its source truly are a mystery (aside from the basic fact that it causes mass to attract other mass, of course)

    Magnetism is a well defined component of the electromagnetic force. We know what it is, where it comes from, and why it has the effect that it does. We've known most of this for a century! The study of electromagnetism came early to the field of physics because it's easy to work with and understand on human scales.

    To be very short, moving electricity creates magnetism; moving magnetism creates electricity. A permanent magnet is magnetic because most of the electrons are spinning the same way, creating magnetism. That's it.

    That is what you tell the grade 4 students.

    Later you can teach them about magnetic domains, dipole moment, electric and magnetic fields and their relationship to radio waves etc... But these are all things we know, and I feel like it's important that kids know that humanity has in fact mastered magnetism.

    Sure there is still a lot to learn, but at this point it's engineering, not science. Practical things like magnetic alloys or optimal field arrangements for motors.

  • Last year my daughter told me her grade 4 teacher had told the class "Well nobody really knows how magnets work" to which my science-obsessed daughter replied "You mean you don't really know how magnets work!"

    I confirmed to her that yes, our understanding of magnetism is about as complete as it can get. Of all the mysteries the universe has to offer, magnetism is not one of them.

  • I really don't see how building a docker container afterward makes it easier

    What it's supposed to make easier is both sandboxing and reuse / deployment. For example, Docker + Traefik makes some tasks so incredibly easy and secure compared to running them on bare metal. Or if you need to spin up multiple instances, they can be created and destroyed in seconds. Without the container, this just isn't feasible.

    The dockerfile uses MySQL because it works. If you want to know if the core service works with PostgreSQL, that's not really on the guy who wrote the dockerfile, that's on the application maintainer. Read the docs, do some testing, create your own container using its own PostgreSQL or connecting to an external database if that suits your needs better.

    Once again the flexibility of bind mounts means you could often drop that external database right on top of the one in the container. That's the real beauty of Docker IMO, being able to slot the containers into your system seamlessly due to the mount system.

    adapting can be a pita when the package is built around a really specific environment

    That's the great thing about Docker, it lets you bring that really specific environment anywhere and in an incredibly lightweight manner compared to the old days of heavyweight VMs. I've even got Docker containers running on a Raspberry Pi B+ that otherwise is so old that it would be nearly impossible to install the libraries required to run modern software.

  • You can download from Spotify using Zotify. Albums, playlists, if you set it to Artist unfortunately you will get a bunch of singles and EPs that you have to clean up.

    If you have Premium you can download at high bitrates, otherwise you get Ogg Vorbis at around 150 ABR. You can automatically transcode to whatever format you want, then I feed it to beets to catalogue and deliver it with Ampache.

    I like the moderate bitrate OGGs myself, as I often stream from Ampache to my phone and our mobile service is quite slow. So this system works great for me.

  • Well said. You can look at the current situation in Canada, where our government has been driving excessive immigration levels despite the fact that we have a shortage of almost all infrastructure at this point. They have tried to call down any opposition to this policy as racist or xenophobic.

    However most Canadians respect the fact that "we are all immigrants" and have no issues with immigrants. And we are tired of being called xenophobic just because we want to slow the rate of immigration until we can rebuild our housing stock, medical system, transportation, and actually create some good paying jobs for people.

    So people like myself who are working/middle class and traditionally aligned with the left as it is supposed to support unions and labour solidarity, are now discarding the left as it has discarded us. A continuous push to devalue labour by bringing more people than are needed to the country is anti-worker, it's "left" but it's the wrong kind of left! We have no party that represents the working Canadian anymore.

  • A cheap tablet makes for a cheap HMI display, literally a fraction of the cost of alternatives.

    "MQTT Dash" makes a great interface to any protocol that you can translate into MQTT (i.e. almost anything at this point) and it's free and robust.

  • Bread

    Jump
  • In days of old, my father ate the bread ends.

    Now that I have a daughter, I am the one who eats the bread ends

    We do this not because we enjoy them, but because it is our duty as fathers.

    That or because otherwise my wife will just throw them to the dog. What a waste of perfectly good bread!
