The first one I have issues with because it touts the multiple CNAME records as a cool hack... The second is worse... It touts it again, along with NOT using one of the more useful features of browsers (Relative links).
What the blogger has against persistent connections to enhance performance I don't know (They really speed things up, possibly more than many connections)... Browsers have a limit of two connections to a particular server for good reasons (Not performing a DOS on yourself being a pretty good one in my book).
