Having the date for each entry could be useful:

puts"Content-type: text/html","\n<h1>Blog",Dir["*.entry"].map{|x|[(f=File.new x
).mtime,"<h2>#{f.read}<hr>"]}.sort.reverse[0,9]

I think I've lost that one too, but I found the following versions in
/tmp:

#!/usr/bin/ruby -rcgi
H,B=%w'HomePage w7.cgi?n=%s';c=CGI.new'html4';n,d=c['n']!=''?c['n']:H,c['d'];t=`
cat #{n}`;d!=''&&`echo #{t=CGI.escapeHTML(d)} >#{n}`;c.instance_eval{out{h1{n}+
a(B%H){H}+pre{t.gsub(/([A-Z]\w+){2}/){a(B%$&){$&}}}+form("get"){textarea('d'){t
}+hidden('n',n)+submit}}}



require 'cgi';H,B=%w'HomePage w?n=%s';c=CGI.new'html4';n,d=c['n']!=''?c['n']:H,
c['d'];t=`cat #{n}`;d!=''&&`echo #{t=d} >#{n}`;c.out{c.pre{t.gsub(/([A-Z]\w+){2}
/x){c.a(B%$&){$&}}}+c.form("get"){c.textarea('d'){t}+c.hidden('n',n)+c.submit}}


require 'cgi';H,B=%w'HoPa w?n=%s';c=CGI.new'html4';n,d=c['n']!=''?c['n']:H,c['d'
];t=`cat #{n}`;d!=''&&`echo #{t=d} >#{n}`;c.out{c.pre{t.gsub(/([A-Z]\w+){2}/){c.
a(B%$&){$&}}}+c.form("get"){c.textarea('d'){t}+c.hidden('n',n)+c.submit}}


IIRC I had a 2 liner, if you allowed  ruby -rcgi  and removed some of the
functionality/bloat.
