Vasiliy Sharapov's questions

I just bought the domain vas.im, I added a DNS rule for vas.im and www.vas.im, then I tried to get apache2 to redirect the latter to the former. I enabled mod_rewrite, appended /etc/apache2/httpd.conf, which follows, and restarted the apache2 service.

ServerName localhost
AccessFileName .htaccess

# Redirect www to non-www
RewriteEngine On
RewriteEngine On
RewriteCond %{HTTP_HOST} ^[url]www.vas.im[/url] [NC]
RewriteRule ^(.*)$ [vas.im...] [L,R=301]

I must have made some mistake, since the www domain does not redirect. I don't pretend that I understand mod_rewrite, so I'm wondering if someone here knows what the issue is.

Sometimes a process comes and goes faster than I can ps aux, I tried watch -d -n0.1 "ps aux | tail" but again, that's restricted to 1/10th of a second. What I really want is to run a command and follow all new processes, one per line, as they spawn. Even processes that run fast. I know strace has abilities similar to this but I haven't been able to get it to do what I want.

tl;dr : is there a way to log all new processes?

I don't want to know much, no more than a line of ps aux would give me, for the current case I just have a process that's spawned by another and disappears, I want to be able to run it, but I don't know what the command would be. Even knowing new PIDs would be sufficient, since I could figure a script that would take these and run ps | grep on these and give me more info while the process is running (assuming hopefully the process is still around when ps gets going)
