Error 404--Not Found

Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

The Cyber Communications Laboratory Group of NTT Laboratories, the R&D affiliate of Nippon Telegraph and Telephone Corporation, last week started the New Implementation of a Log-structured File System (NILSF) project to develop a log-structured file system for the Linux kernel 2.6.

According to the research group, "A log-structured file system has the characteristic that all file system data including metadata is written in a log-like format. Data is never overwritten, only appended in this file system. This greatly improves performance because there is little overhead regarding disk seeks." The NILFS Project is on open source effort that the group is releasing under the GNU General Public License. This is not the first project of hits kinds, however, the group sites three other log-structured file system projects or implementations on its Web site.
