This is done very often in physics; without this feature I largely
consider any units system useless.

Hi,
what is your view on using implicit imports? Should they be allowed?
Or decided an a case by case basis? A quick search has revealed there
are 44 places in Sage where
implicit import is used:

I spent some time a couple of months ago thinking about how units

I figured I'd give everyone an update on how things are going with the
Sage packages. I believe (but am not certain) that all of the Sage

past.

In anticipation of SD9, I tried out viewing sage generated X3D files

Hello folks,
this is 3.0.6.rc0 which should be the last release before the ISSAC
2008 special 3.0.6 release for Wednesday. We fixed a bunch of issues
and were a little less conservative than I though, but what could go
wrong ;)

When dealing with lots of these, or when dealing with matrices and

working on the package for Sage itself (rather than its dependencies).

Dear William or anyone
I tried to unify the objects in user_db and users and let the
passwords proxy ldap if they are
not the default users (which could use the basic hash+salt method). I
ran into this odd problem
that on startup it was trying to set a non-existent admin with the
password.
