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

Startups for a stronger Resume?

When the whole web is abuzz with keywords such as Ajax, Web 2.0, Meebo and all, there is some uncertainity about how this new Internet Bubble will shape up.

Mike at Techdirt writes that some of these new startups may be only to actually stand out for the crowd and act as a strong resume.

While the complaint is that so many of these companies are built to flip rather than to be sustainable businesses, some are noticing that this process is really just a better way for some to stand out and get a job. You build a company quickly and cheaply that gets some attention, and a bigger company comes along to scoop up your company, giving you a nice "signing bonus." In effect, the purpose of these companies is to act as a strong resume to stand out from the crowd.

Pottermania

I'll have to admit that the nature of Pottermania is beyond my comprehension capabilities! As more and more fans of all ages and countries immerse themselves in Harry’s adventures, adding fuel to the belief that Pottermania is inescapable, I am purely and simply baffled by its ability to appeal to all ages.

Bored by the inactivity prevailing in this muggle world, I began to read the first one of the series and immediately concluded that reading beyond the tenth leaf was something impossible. Undeterred, I watched the first movie. I Hated it. But with the evil-wizard becoming apple of more and more eyes with every passing moment, around the world, it could only have been something wrong with me and so I watched the second movie. And then it became so easy to establish that I loathed the Potter Kid!

Just a passing thought - "Would it be a bad idea for a Potter special appearance in Oliver Twist? The poor kid could do with some wizardry."

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.
