I’ve just downloaded my whole GMail account via POP3. Each message is stored as-is, including headers and attachments in base64, in a seperate file.
du -ms on the folder with all emails tells me:
While GMail tells me:
You are currently using 2079 MB
Why this difference, I asked myself. Was there a difference in the way e-mail was stored? Actually I stored my e-mail very inefficiently. E-Mail is 7bits encoded — every character is 7 bits — where my FS (like virtually every other) stores each character in a 8bits. Lets calculate the actual size of email on my disk:
>>> 2117 / 8 * 7
It gets even more absurd considering that the most part of that space is used by attachments in emails, which are encoded in Base64, which uses 6bits per character. At least 50% of these 2GB are attachments, thus:
>>> 2117 / 8 * 6.5
Why am I using 2079MB according to GMail?
GMail wouldn’t require 2079MB for my emails, they probably compress all attachments and old mails, they won’t even come near that 2079MB. It would therefore seem logical that they would use the real size of all emails — which should at least match the 1848MB or 2117MB, but it doesn’t.
Anyone got a good guess?
Disclaimer: This isn’t in any way meant to be anti-gmail — I love gmail, everyone loves gmail! I’m just curious.
It seems that the place to get a gmail invite has been closed down: isnoop.net/gmail.
I haven’t got a place anymore to send my gmail invites so I have them spare again.
If you want a gmail invite, just mail to bas.westerbaan [curly thing] gmail.com.
Don’t go to every forum and post a topic that people can get them by mailing you.
Just donate them to http://isnoop.net/gmail/!
It is the second link in google when searching for gmail invites. (first is google itself)
If you want your invites to be used send your invites to them, as I did.
