Mac Mail application speedup,cleanup

For those of you experiencing
slowdowns on Mac OS’s Mail application over some time, this might
be a cheap trick for you to get back speed and disk-space.
Mail, is keeping track of mail message subjects in a database, to
quickly scan, search and organize threading in your
mailboxes.The good thing is: once you delete a mail, it is also gets deleted
in the database…
The bad thing is: a database needs to be maintained, and this is
not done automatically…

What does this mean now….
…your database deletes items by reference, but it does not free
up the allocated disk-space, thus blowing up your overall database
size which leads to longer access times as more (empty) data needs
to be parsed through.

The solution:

While your Mail application is NOT running…
…use a terminal and go into “cd ~/Library/Mail”…
…open the database with: “sqlite3 Envelope Index”…
…and free up the already deleted database disk-space using:
“vacuum subjects;”…
…et voila, quit sqlite3 and you’re done.

Mail will be quite fast again, and your disk capacity should show a
few more free blocks.

PayPal transaction token keyoffer

Today I got my PayPal trasaction
token.
DSC02850Using a token generator is much more safe than using traditional
passwords, as they generate a time based one-time valid
token-number which is then used to sign a transaction.
Phishing of useraccounts and passwords might still be possible, but
of less use, as the token code is only valid for a short time, and
one-time only.
DSC02857

Compared to the token of my bank account, PayPals token is a little
bit smaller, and uses a button to activate itself other than
pulling the left side on the other token.
The number of digits is equal, but usually a secondary secret PIN
is used to complete the code.
For example you may need to enter: tokencode+PIN or PIN+tokencode,
or even PIN1+tokencode+PIN2(or a displayed session number)

Finally PayPal also delivers a nice laminated note with a top ten
of essential security behaviour rules, as well as a shart manual on
usage of the token, and helpdesk information.

All in one: I really appreciate PayPal going this direction, what a
great idea, I just hope lots of banks will follow PayPals example
on how security can be increased efficiently, as there is a big
demand for this on the customer side, but only a few banks or
transaction providers offering such a service.

Get your token now from PayPal’s special offer: “Der PayPal
Sicherheitsschlüssel.” (search on PayPal.com for offerings in
your language/country)

…but this could be the answer to all of your problems:

A cooled beer can throwing robot companion, ready to serve you

Mac – Eve of destruction

So less bytes and so deadly:

1000000001000100007D000000000000
000000006461746120070300

I’m starting to get angry now, as I filed in this bug 1 year ago,
and there’s still no fix for such a trivial bug.
Also I filed it in as a security issue since you can crash every
Mac from remote with these little numbers, but Apple degraded it to
be cosmetic only as it is not possible to alter or execute
code.
I guess they’re not anymore interested in fixing Tiger, as the
Leopard is waiting for its victims…..

Hint: Check for zero values before dividing…..

What about the Tanuki ?

You might have heard it or not: A
Tanuki, seen almost everywhere around temples in Japan,
is a famous native japanese animal there. To be more precise it’s a
racoon dog.
While looking around for a nice picture of a Tanuki for my website
layout I just found an explanatory figure to better understand the
eight lucks a Tanuki is a symbol for.

More Theme Wrangling

to be continued… not yet finished,
stay tuned.More changes happened as you might have noticed.

The fresh green vine leaves are gone, and finally sakura
cherry-blossom is to become my final layout, for the springtime
at least.
(Hopefully browser-caching didn’t steal my show. So if you’re still
seeing a green/blue layout SHIFT-RELOAD your browser, or clean your
cache.)

I hope you like it, (too).
