TL;DR:
If you use Thunderbird, once in a while, do this:
File: Compact Folders
This may be the only way to get space back
for deleted messages (I'm not sure).
Now for the war story.
One of us uses Thunderbird to read mail.
It stopped working yesterday, with no useful diagnostic.
In particular, it would no longer pick up mail from our POP3 server.
There was no signal to the user.
I looked in the Error Console (meant for developers, not users) and
saw two messages, the first being:
tb.account.size_on_disk - Truncating float/double number.
What does this mean?
First guess: Javascript stores numbers in 64-bit IEEE 754 floating
point representation. A large integer may not be precisely
represented. But there are 52 bits for the fraction AKA mantissa and
2^52 is very very large. My mail files were at most a small number of
gigabytes - perhaps 2^32. So this cannot be the explanation.
Googling didn't help: the message showed up in posted logs but wasn't
relevant to failure to fetch mail. Still, some did suggest that a
Compact Folders command was in order.
About three gigabytes of space freed and the first message
disappeared.

We still could not pick up mail.
Hope this is okie dokie to mention.
We're recruiting an all-rounderjunior/intermediate system administrator.
Remote likely most of the time, but would need to be able to get to the
office in Newmarket about once a week and to the colo in Scarborough
when necessary (not very often).

Happy to elaborate if anyone is curious.

Hi folks,
Both shellworld, and dreamhost, use Ubuntu as the basis for their shell
workspaces.
Sharing that up front, as this may be tied to Ubuntu.
There is a program called screen, apparently common across some Linux
distributions.
one can create the equal of a screen shot,
screen www.website.com
followed by control a -h.
This creates a file called hardcopy, with numbers going up for each file.
However, when I run
screen www.site.com
Regardless of the site I get.
screen cannot accept www.site.com no such file or directory screen is
terminating.
Suggesting that there must be a configuration issue since Debian users I
know <and who have likely built there own stuff> are not encountering the
same problem.
Any tips?
Kare
