Linux: 'Expires' website speed boost

http://linux.yyz.us/speed-boost-expire.html

Linux: 'Expires' website speed boost. While admins and webmasters use HTTP headers such as Last-Modified. To influence how browsers and proxy caches cache their content, many are unaware of how caching logic functions "under the hood", and as a result, many are unaware of a secret weapon in the webmasters toolbox: the Expires. It should obvious that the answer to this question cannot be obtained from a last-modified timestamp. Such a timestamp tells us nothing about when the content will be next. Intelli...

IPv6 on Fedora Core mini-HOWTO

http://linux.yyz.us/ipv6-fc2-howto.html

IPv6 on Fedora Core mini-HOWTO. Thanks to David Woodhouse for showing me how to do this. IPv6 appears to be very, very close to a Just Works(tm) state. IPv6 automatic tunnelling ("6to4") is a method designed to ease the introduction of IPv6 into existing IPv4 networks. The designers of IPv6 created a special prefix, 2002, under which the entire IPv4 address space can be mapped, with enough address bits left over for 65,536. For further reading, Fedora users may investigate. Fedora Core 2 only. Allow ipv6...

Linux: Why software RAID?

http://linux.yyz.us/why-software-raid.html

Linux: Why software RAID? The "software or hardware RAID? Question comes up often. I think I answer the question at least once every six months or so. And the responses to such a question are often filled with, in my opinion, inordinate praise of expensive hardware RAID solutions, and inordinate scorn for software RAID. This page is my attempt to explain a Linux kernel engineer's point of view on the matter. This comparison excludes SAN and other external RAID. Why prefer Linux software RAID? RAID5 XOR s...
