Windows 95 ran on 4 MB, and very well on 8 MB. I believe I ran Linux with fvwm2 on 8 MB as well.
Of course 64-bit and higher resolution increase RAM requirements to some degree, but I’m still not sure what Openbox needs 600 MB for. ;)
> Fast forward to today. A program to load /usr/share/dict/words into a hash table is 3-5 lines of Perl or Python, depending on how terse you mind being. Looking up a word in this hash table dictionary is a trivial expression, one built into the language. And that's it. Sure, you could come up with some ways to decrease the load time or reduce the memory footprint, but that's icing and likely won't be needed.

5MB here. 5MB there. No one notices ;)
