Can also recommend Just For Fun - that Finnish sense of humour doesn't come across well, and while he's good with English he certainly isn't Shakespeare, but it does fly by.
History of Linux, abridged: Linus was using Minix on his own PC while at University, but was a bit fed up with its networking capabilities, so he'd written a toy operating system for a couple of his classes. While experimenting with adding features to it, he deleted his Minix partition by accident. Might as well continue with the one he'd written, since it was almost capable enough to be a daily driver. Publish the source, get a few collaborators in to add in the features that they found most useful, repeat. Boom.
Got given a ThinkPad P15v (upgraded to 64GB RAM) as my work development machine. It's heavy, it runs absurdly hot, and it chews up the battery - an hour with IntellliJ open is very optimistic. Got a ThinkBook 14-IIL (16GB) as my own personal machine - hugely prefer it even for development work, much easier to carry about, battery lasts for hours, doesn't seem any slower in practice.
They both seem pretty robust and they both run Linux perfectly, but unless you absolutely need need need a discrete graphics card or loads of ram I couldn't recommend the Pad, and they are damn expensive for what they are. Book on the other hand - great machine. Crap for games, but excellent in every other regard.
