Case Sensitive E-mail Addresses

Not often do I post two entries here in quick succession that completely stump me. The earlier one about Mozilla Browsers being more vulnerable than IE and now this whole thing about the email address being case sensitive.

New York Times says:
The domain-name portion of the e-mail address - the part after the @ sign - is not case -sensitive, but the first part of the address may need to be typed in exactly as given. This rule is explained in RFC 2821, the document laying out Internet e-mail standards, found at faqs.org/rfcs/rfc2821.html.
This certainly is news to me. I never had thought that my username was case sensitive. Apparently, in most cases they aren't. The RFC2821 states:
The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. Mailbox domains are not case sensitive. In particular, for some hosts the user "smith" is different from the user "Smith".
But then, I am not the only one who remains in this blissful state of ignorance. Hundreds of thousands of management aspirants who filled out the CAT application forms to India's premiere B-schools just last month would have noted that the email address field had only uppercase options!

Hi Enginerd,

You have a riveting web log
and undoubtedly must have
atypical & quiescent potential
for your intended readership.
May I suggest that you do
everything in your power to
honor your Designer/Architect
as well as your audience.

Please remember to never
restrict anyone's opportunities
for ascertaining uninterrupted
existence for their quintessence.

Best wishes for continued ascendancy,
Dr. Howdy

Gmail Chat Disabled

The fact that it happened does not surprise me but that it took so long for our network administrators to figure it out does. And if you are wondering how do you disable Gmail's chat features on your network, you only need locking DNS lookups to chatenabled.mail.google.com , by returning 127.0.0.1 .

Community effort to create a single persistence model for the Java community

A community effort led by Sun Microsystems is aiming to create a single 'Plain Old Java Object' persistence model to provide a single object/relational mapping facility for Java app developers in J2SE and J2EE. Paul Krill writes In a letter to the “Java Technology Community” on Friday, specification leads on Java Specification Request (JSR) 220, which is the proposal for Enterprise JavaBeans 3.0, and JSR-243, for Java Data Objects, state that the two technologies feature divergent persistence models. “This divergence has caused confusion and debates among Java developers, and is not in the best of interest of the Java community,” said JSR-220 leader Linda DeMichiel who also is a Sun employee, and Craig Russell, a staff engineer at Sun who leads JSR-243. “In response to these requests [for an end to the unwanted divide], Sun Microsystems is leading a community effort to create a single POJO (Plain Old Java Object) persistence model for the Java community,” the letter said.
