Those both sound like brilliant servers! I'm not laughing at all. If my mac
mini is good enough for sky rim, it's good enough for web hosting for sure!
Can we just use camping.io?
I think starting simple is a good idea. Databases are pretty cool among web
developers for various reasons, but I think are totally unnecessary for most
smaller experimental applications. For a beginner, I'm inclined to have
key-value databases. A really simple key-value database would work like this:
sections = key.hash.to_s(36).scan(/.{0,3}/)
sections.delete ""
Dir.mkdir sections[0…-1].join('/')
File.open(sections.join('/') + '-value', 'w') do |file|
file.write JSON.generate(value)
end
add in some file locking, and everything is pretty cool. It splits up the kevin
to a series of about four directories and then a file, and conveniently "fff"
in base36 is 19995, which is a very nice maximum number of things you'd ever
want to put in a single directory if using something like EXT4 or HFS+. Of
course, if using a B-Tree filesystem like reiser, btrfs, zfs there is no such
limitation so you can skip the scanning joining thing and just open
"database/#{key.hash}" and put a value in that.
Pretty cool, no? It's really easy to turn something like that in to what seems
from the outside to be a persistent hash.
I was working on another thing called ForeverHash, which was the same sort of
idea, but used flat files. If people are interested I'd be curious enough to
revive that project with more of a CouchDB inspired design.
I like all these filesystem based solutions (sqlite, crazy hash in folders,
flat file key-value db's) because they can be backed up and restored via webdav
or sftp or whatever, and you don't need to do any weird stuff of configuring
which ports and usernames and passwords in your database abstraction. I prefer
the idea of having a little key-value filesystem db written in clear straight
forward ruby code, because it means kids learning can see how it works and hack
at it - as nice as sqlite is, it is in no way transparent. You at least have to
learn SQL if you want to play with it's innards, and possibly C.
