Theoretically this is possible on the outer three gas giants. As Jupiter goes, it's gravity is far too strong, plus it has the most intense radiation. So you would want to set up shop on one of the three outer gas giants. Gravity on the outer gas giants is close to Earth's, about 1 g for all three of them. There are actually layers of their atmospheres with Earth-like temperatures, but they are low in the atmosphere where the pressure is extremely high (we're talking about enough to liquidity hydrogen) so you'd want to be higher up. It's pretty cold in the upper layers, plus you're far away from the sun. Venus is probably a better target for a cloud city - about 50km up the atmospheric pressure about 1 atmosphere, temperature is about 0C, gravity is about 1G, and plenty of sun during the day. Plus the atmosphere is mostly CO2, which is denser than breathable air, so a balloon full of breathable air would float on Venus.

The last B-52 made was in 1962. The ones left flying all all the last B-52H variant, though NASA had a B-52B operational until about 10 years ago.

Many 747-100's were converted into freighters and I assume some are still flying. There were several flying in Iran for a while, but not sure of their current status. GE uses one as a testbed for engines that's very much still active, and it was one of the first ones flying in 1970. There may not be any left in regular passenger service though.

Actually, pretty much every Linux distribution I've ever played with (that comes with an installer) gives you the option of not installing a boot loader if you don't want to. Some will even make an alternate boot media for you to get into your Linux installation, such as a boot floppy or a USB stick, while others will leave it up to you to figure it out. And if you do choose to install Grub, they will almost always add an entry for any Windows installations it finds.

Of course, there are the Linux distributions that come without installers, but if you're that hardcore you know what you're doing anyway.
