    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.

    Sweatshirts are double-layered pullovers, typically non-woven. Sweaters are single-layer pullovers, typically knit. Jackets have buttons or zippers. Hoodies have hoods and are made of fabric (e.g. raincoats are not hoodies).

    You can have hoodies that are also sweatshirts, or hoodies that are also jackets.

    This garment pictured in your post is a jacket. It is also a hoodie. It is neither a sweatshirt nor a sweater.

    This is just my interpretation of the situation. I don’t know of any formal classification system for outerwear.



  • Yeah, I know what a hydrogen fuel cell is.

    What I’m saying is that the cost to develop hydrogen infrastructure, the complexity of it’s distribution, the risk due to its high volatility, and the uncertainty of a relatively underdeveloped technology all seem to be losing to batteries, which are very mature tech and are already in the supply chain and for which we already have a well developed electricity distribution grid.

    I just don’t see what investing in fuel cells will do other than slow the adoption of zero emission vehicles by another decade.
