Earlier tonight, I came across this handy link worth calculator. It’s got a nice ajax interface, and does the calculation for you based on some general criteria.
Now that I’ve thought about it, I went ahead and added an advertising campaign banner to the search engine forum to try and sign up more advertisers.
When I ran the unix command “ls -la”, a .nfsXXXXXX file showed up…this was created as a temporary file when an open file was deleted on NFS mounted file systems. The file is created so the unfinished process can continue writing/reading to that file which was deleted. It stays around even after the process has finished.
Thanks to the University of S. Wales’ Engineering Dept.’s Deleting .nfs files article.
