mod_vhost_hash_alias is an Apache HTTPD module that allows mass hosting with good distribution across a unified directory namespace. Administrators no longer have to use complex regexps with mod_rewrite, since they can use mod_vhost_hash_alias to do a better job and use fewer resources. mod_vhost_hash_alias is a component of the VHFFS hosting platform which is used by the Web hosting provider Tuxfamily.org.
CD-ROM Digest is a program that checks a multi-track CD-ROM. It reports the MD5 digest and size for each track on a CD-ROM. The digest is done as the track is read, without dumping CD-ROM data on the hard drive. This tool helps users that are burning a multi-track CD-ROM to check the result.
