Thinking of starting to do some home server/networking stuff. A lot of technologies rely on a bunch of infrastructure for them to be viable. If online map services went down many mobile devices would cease to be able to function as maps, for example.
We've lost a lot of infrastructure and many services that existed in the past and they've been replaced with worse alternatives. If I want to bring my old thinkpad out with me to a cafe the number of websites I can visit comfortably is dwindling. But, I think if I can set up some of my own infrastructure at home, I can do a bit to negate that. Basically, if I have a powerful computer at home, I might be able to use it as a proxy between modern services and my older devices. There are programs that will look at a web page and then render it as a clickable, mapped JPEG that can then be beamed to another computer on which an older browser can be used to interact with a site. Obviously this would only work with static content but it could help. I don't remember exactly what this software is called but I'll let you know when I find it.
Another thing I could do is allow myself to access a virtual machine from outside of my house, so I could use new software if I wanted to on my old laptop when I'm out, and I'd have access to much more powerful hardware that way.
