comment File shows different size after copying to another directory
FWIW and in contrast to some of the prior comments, du -k lists kibibytes, not some arbitrary filesystem-dependent block size. Different filesystem block sizes are not the direct cause of this issue. That being said, filesystems are allowed to store files however they want, using however much (or little) space as they deem suitable, and there never is any guarantee that a copied file takes the same amount of storage space as before. There are all sort of filesystem-specific reasons why the copy could take more space, but a good first suspect is that the original file may have been sparse.

comment Need IMAP client that does not wait and wait and wait for confirmation that copy was put in Sent folder
In other words the client sends the command to save a message to a folder (which is an IMAP APPEND command) and the IMAP server simply doesn't reply at all to his command? That would be a protocol violation on the part of the server and it would not be surpising for many or most IMAP clients to have dificulty tolerating that. That Rackspace's IMAP server would be violating the protocol like this sounds fishy.

comment How to rename to existing folder
@kumarM I don't know... I guess there had to be something already existing inside the deployables_05_14_2013 directory but no matter what I try I cannot reproduce the "subdirectory of itself" error message. As for the rename command, I was unfamiliar with this command but I read the manpage. It looks like you are using it incorrectly: the first argument is supposed to be a Perl substitution command, not a filename.

comment How to rename to existing folder
@terdon It may be natural in spoken English where you say the name of the month, but I don't find it natural at all in writing. On a more objective note, the biggest flaw of this format is that it is probably going to get misinterpreted whenever the day number is 12 or less (because it looks like a month number). The workaround for this is to use the month name instead of number... which is exactly what is done in speech.

comment How to rename to existing folder
Also, it looks like you are using the mm dd yyyy convention for date formats. This convention is illogical and problematic because it is neither more-significant-toward-less-significant nor less-significant-toward-more-significant. You should consider using ISO 8601's YYYY-mm-dd (most-significant-to-least-significant), or, failing that, at least use dd-mm-YYYY (least-significant-to-most-significant).

Please show ls -l instead of just ls. I wonder if perhaps deployables_05_14_2013 is a symlink to deployables.

comment Quality of service in IPV6
I guess I can't comment without buying and reading the paper. It's true that IPv6 has a flow label field and IPv4 doesn't, and they mention that in the abstract, but I have implemented and managed QoS networks before and it's all based on DSCP, nothing about flow labels.

Your assumption is wrong. IPv6 does not solve IPv4 QoS problems.

comment Is a DNS allowed to reply with different IP than the one stated at the records in the domain name registrar?
Do you mean whether the in-zone A or AAAA record for a nameserver can be different from the glue record supplied by the delegating nameserver?

comment OpenSSL and what encryption method to use
Also, the second argument to openssl is not an "encryption type" but a subcommand, to tell it what kind of action to take. For example, manupulation of X.509 certificates, manipulation of keys, signing, encryption, certificate generation, message digest calculation, etc...
