  • It’s perfectly possible on Linux to have several network adapters with the same IP address, or several default routes.

    Most server applications will listen to 0.0.0.0 address, which means all network interfaces. Any incoming TCP connection will remember it’s network interface, and the server will send responses to the same interface.

    This will not work for UDP connections, and for outgoing TCP connections - they will always choose the network interface with the lowest metric, which you can print with ip r command.

    This does not include advanced techniques like bridge or bonding or iptables routing - you need to run special commands in the terminal, which you cannot do just by clicking your mouse in system settings app.




  • Fast food is already as automated as it can be. Replacing cooks with robot kitchen is looks good as a management dream, but anyone who tried it quickly discovers that you need industrial robots, and they are fuckng expensive, and you need engineers anyway to maintain them. So you are replacing cheap cooks with outrageously expensive engineers.

    “But no”, some ignorant CEO says, “we’re not assembling cars, we don’t need pneumatic robot arm that can lift 10 tons”. Yeah, you still need a robot arm, and it’s just a miniaturized industrial robot, not any much cheaper.

    But robot kitchen exist, and they are actually very profitable. Go to your nearest grocery shop. 99% of items on the shelves were produced by a robot. Everything in a plastic wrap, everything in a jar, was produced on a conveyor. Even fresh produce involves some kind of automation.

    So robots won’t fry your potatoes, because french fries have really short shelf life. Otherwise they totally could, but hiring a cook is cheaper.









  • SDL provides you a framebuffer with 640x480 pixels and 24-bit color, with a delicious pixel-perfect 8x12 monospace font, on every OS and every device, and this is everything you will ever need. Titlebar? Close button? Your app is perfect, it needs no close button. It will be running 24/7 in a fullscreen mode, and the user will be happy! Other apps? Pah! Let them run on a second, smaller monitor!
