  • People have attached pens to 3d printers and used them to write letters, effectively print. Most consumer 3D printers are useing or based on open source software.

    I think the issue is, printers are relatively cheap to buy and replace. So building your own and programming it hasn’t been necessary. Where as 3d printing was completely in accessible before the reprap movement. 3D printing software is open source as it is motivated by people wanting to build their own machines that could build machines. Something you couldn’t easily buy.


  • A small computer, large capacity ssd and two WiFi interfaces (2x usb dongles, or dongle plus usb).

    Small computer could be anything: raspberry pi (or generic and), nuc mini pc or laptop. If you want to use it without a plug you’ll need to add a battery, usb c powered devices could be more convent to power from a battery.

    A ssd is better for this use case. Not because it’s faster, but they are more resilient to being knocked about and dropped. They are also much smaller, especially M.2, and aren’t fussy about how they are mounted.

    The two WiFi interfaces would allow you to create a WiFi bridge to access the internet through a WiFi network and access your media server. It would need some configuration, you may also need to have the computer act as a router if you want to use multiple devices without reconfiguring.

    It may be easier to have your device act as a WiFi hotspot and have the media centre automatically connect to it. This would make it difficult for multiple devices to use it simultaneously, and you could accidentally allow the media centre to do all its updating and downloading over your mobile connection.

    This type of thing is going to be expensive and troublesome to configure unless your already experienced with that sort of thing.

    I think a better solution, especially if you already have a media server. Is to set your media server for external access.

    To get media when you don’t have internet, buy a large capacity flash drive (or external ssd/hdd). When you have access to your media server download all the content you want on to the drive. I think iOS jellyfin can do this without much modification.

    Once out of range of your media server. Delete the content you’ve watched on your device (iPad) to free up space. Connect the external drive through the usb port on the iPad, copy over the next lot of content you want to watch. Disconnect and then watch the content.

    Jellyfin can download the content, but you may need another app to play it when you don’t have access to the media server.

    This approach lets multiple people access a much larger amount of media, effectively simultaneously. It doesn’t require a large amount of often expensive local device storage - you use cheap external storage. It much less expensive if it breaks or gets lost and has very little configuration -if you already have a media server running jellyfin.




  • Nixos is an os that’s defined by its config stored in .nix files. Everything is defined here all the software and configurations. Two people with the same script will have the exact same os.

    Any changes you make that aren’t in the scripts won’t be present when you reboot.

    You could maintain a very custom linux distribution (kinda) by just maintaining these config scripts.

    So a user wouldn’t need to install all required software and dependencies. They could get a nixos and the self-host config and adjust some settings and have a working system straight after install.



  • Most common maybe. I feel most windows users aren’t actively choosing to use windows. It’s just what they are left with.

    People usually choose to use Linux or Mac. As Linux is rarely preinstalled or like Mac more expensive (when it comes preinstalled) than the windows devices for sale. I’m not convinced given a fair shake, windows would have the market share it does.

    Servers have highly informed people making decisions about their operating systems. When weighing the options about uptime, security, etc they rarely choose windows. Cost isn’t really a factor relative to the price and operation of the server.





  • This is a common misconception of the placebo effect. The placebo effect is a measurement issue, not an actual benefit.

    Tests are corrupted by using the reposnes and judgement of humans. People will say they had some sort of benefit because of expectations, poor recollection and politeness. It doesn’t mean a benefit was gained. A placebo group allows researchers to quantify how much the placebo effect has on the data they gathered, they can then see if the experiment they did had any effect. Placebo is literally our definition of zero effect.

    Anyone telling you placebo is a good thing is wrong, misinformed or deliberately misleading you. In many countries it is illegal for doctors to prescribe ‘placebo treatments’. They will still recommend such things to their patients - not because they work but because they get the patient out the door and less likely to come bother them again.
