  • I think the reason Zealandia is called a “submerged continent” is because it is made of continental crust rather than oceanic crust.

    But IMO the best geologic definition of continents is by tectonic plates, which mostly matches up with the cultural definitions of the continents.

    For the major continents, we have these plates:

    • North American
    • South American
    • Eurasian
    • African
    • Australian
    • Antarctic

    There are several smaller plates too, like the Caribbean, Indian, and Arabian plates. IMO, we should consider these independent continents.

    There is also a dedicated Pacific plate. The ring of fire is the border of this plate.

    New Zealand / Zealandia is on the ring of fire. Half on the Australian plate, half on the Pacific plate. You can actually see the border of the two plates when you look at the topographical map of Zealandia.






  • You don’t need to provide root access just because you used GPL code, you just have to follow the GPL.

    Well, to follow version 3 of the GPL, you do actually need to provide effective root access.

    Specifically, version 3 of the GPL adds language to prevent Tivoization.

    It’s not enough to just provide the user with the code. The user is entitled to the freedom to modify that code and to use their modifications.

    In other words, in addition to providing access to the source code, you must actually provide a mechanism to allow the user to change the code on the device.

    The name “Tivoization” comes from the practice of the company TiVo, which sold set-top boxes based on GPL code, but employed DRM to prevent the user from applying custom patches. V3 of the GPL remedies this bug.

    However, Linus’s kernel was more elaborate than GNU Hurd, so it was incorporated.

    Quite the opposite.

    GNU Hurd was a microkernel, using lots of cutting edge research, and necessitating a lot of additional complexity in userspace. This complexity also made it very difficult to get good performance.

    Linux, on the other hand, was just a bog standard Unix monolithic kernel. Once they got a libc working on it, most existing Unix userspace, including the GNU userspace, was easy to port.

    Linux won because it was simple, not elaborate.
