We're considering purchasing an application,
which stores some data in the filesystem, and
some data (meta data and links to files) in
MS-SQL.
We need to be able to create a backup wherein
the database and files are "in synch" (in other words,
in a consistent state). We need to maintain the
"referentia l integrity" between database and files.
What I'm thinking of is something like this:
1. stop the application server
2. set database to readonly (flush updates
from cache to disk)
3. backup database to disk files
4. back up application files and backup files.
(We could use "snapshot" capabilities of our disk
hardware, so that the backup could run against the
snapshot; that would minimize downtime.)
4. set database to read_write; restart app server
Recovery scenario would be:
1. Stop application server.
2. restore application files and database backup files
3. restore database from disk backup
4. restart application server
Is there a simpler way to get a "point in time" backup
of application files and the database?

The first place to ask would be the vendor - find out what their
recommended backup strategy is, and how they say you should recover in
case of failure. If they can't give you a good answer, then you should
make that fact part of your decision.
The snapshot backup might be a good option if you already have the
hardware to support it - you probably wouldn't need to stop the server
at all in that case.

I have a table of points, actually zip codes and their points.
If a point is an X, Y pair, how do I extract X from a point? (And how
do I create or insert a new point (X, Y)?)
I am given a latitude, longitude pair and I would like to determine
the closest zipcode. I can do this using point_distance, but I wonder
if there is a faster way. If I can extract the separate x, y values
from a point, then I can define my own distance metric...

OK, I realize that what I am asking here is not likely to have a
answer within the C standard. Nonetheless, it is not specific
to any particular platform, so I'll hazard the question anyway.
A C double can be aliased by an array of unsigned char, to which
any desired byte pattern may be written. Is there any somewhat
portable way of assigning a byte pattern such that the result
will, with very high probability, _not_ count as a valid...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
