I'm a complete newbie to postgres so please look the
other way if these questions are really stupid.
Is it legitimate to have one database per data file? For
organizational and backup purposes, I'd like to keep the
database files for each of several projects separate.
This means, e.g., that postmaster must have multiple
instances going simultaneously?
I'm thinking the answer is NO because, for one, the TCPIP

As far as I know, Perl is known as "there are many ways to do
something" and Python is known as "there is only one way". Could you
please explain this? How is this possible and is it *really* a good
concept?

Hi,
I'm curious about server load and download time if I use one big
javascript file or break it into several smaller ones. Which is better?
(Please think of this as the first time the scripts are downloaded so
that browser caching is out of the equation.)
Thanks,
Peter

dear all,
a simple quetion for database experts.
can three datatables be updated at the same time (from one page)with
one table having one primary key
and other two tables are having that primary key as foreign key in
there tables.
tables with foreign keys are linked to parent table(having primary key)
with one-to-one releation.

I come from a background of Java and C# where it is common practise to have
one class per file in the file/project structure. As I have understood it,
it is more common practice to have many classes in a Python module/file.
What is the motivation behind it, would it be a bad idea to have a guideline
in your project that promotes a one class per file structure (assuming most
of the programmers a background similar to mine)?

Hi all,
apologies if this seems like a pretty basic question - but can an element
have more than one class?
if so, how do you set them ?
and how does the browser give priority to a class over another ?

I have an mdb with a *projects* table. I also have a *timecode*
table.
Projects and timecodes are related by a one-to-one relationship but I
do not want to simply add the timecode field to my projects table for
the following reasons:
-Not all projects have a timecode
-Not all timecodes have a project initially.

Forgive me if this is a foolish question. I "play" in Access and have only created a few rather simple relational databases. My knowledge and experience is limited. I have no formal training, just picked up a few books and have gone from there... I'm not sure how to relate my question using the accepted shorthand, so I'm afraid this will be a narrative description.
I am using Access 2003. The database is for property management. I have...

We all know that one-to-one associations are non-lazly fetched but during this fetching the filters are not applied.
I debugged hibernate code and found that hibernate finally calls EntityLoader.loadByUniqueKey() method:
public Object loadByUniqueKey(SessionImplementor session, Object key)
throws HibernateException {
return load(session, key, null, null);
}
I can understand that why filters are not applied because all one-to-one...

I have posted this question in hibernate forums also.. As this forum is related to java, i am posting it here also ...
In hibernate, presently one-to-one associations are fetched non-lazily...
I know that this is done because, hibernate requires to fire 1 sql to find whether proxy can be created or not...
and if it has to fire 1 sql, then why not to load one-to-one object itself in 1 sql instead of creating proxy of it (in 1 sql).

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
