  • 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.














  • It should be the 2013 borders. Before the invasion of Crimea. Russia agreed not to invade Ukraine, in exchange for Ukraine giving Russia it’s nuclear weapons. If Russia doesn’t give everything back, then it can’t be trusted to make any deal with any nation. Including peace deals.

    Any agreement needs Ukraine to get all it’s territory back, and allow them to join NATO. Russia can’t be trusted. But they won’t challenge NATO directly. Europe also needs to take defence more seriously. Only eastern Europe is really taking the Russian threat seriously. Western Europe was fooled into thinking they won the cold war. Russia and China never saw it as over.
