I am hoping that someone more experienced than myself can point me towards
what might be the fastest data lookup method to use for storing ip
addresses. My situation is that I will need to maintain a list of perhaps 50
ip addresses to be used in a packet sniffing application. For each packet
that goes through the application (which will be monitoring all traffic
through a switch), I need to see if an entry for the source ip of that
packet...

I apologize if this is a RTFM question, but I have not been able
to find a definitive answer elsewhere.
Does a "REINDEX TABLE" lock the table while it is working?
Can applications write data to the table during the REINDEX?
I am working on a real-time application that handles over 2 million
"events" per day and runs 7-by-24. Most of these events involve an
UPDATE to one or two tables, though a small subset involve a bit
more work. ...

Help!
I have a table that multiple processes must be able to
write to concurrently. However, it for some reason
gets locked in exclusive mode. I narrowed it down to
one SQL statement + some weirdness with foreign keys.
To debug this, I opened two psql sessions and typed in
the sql statements manually. Here is the situation:

as wat ive mentioned in the title.. im would like to know whether the a
particular record/table is being locked in my program. some of the
methods which i would like to develop are as below:
Lock(KEY, SQLCODE)
- to create a lock. Returns 0 on success, 1 if a lock already exists
and -1 on failure with SQLCODE. There is no necessity to use IsLock()
for checking if a lock exists or not, just insert the record and check

I'm having problem with using DAO recordset to append record into a
table and subsequent code to update other tables in a transaction. The
MDB is Access 2000 with the latest service pack of JET 4. The system is
client/server, multiusers based. The MDBs are using record locking.
Here is part of the code:
Dim wkSpace As Workspace, db As Database
Dim rstTrans As DAO.Recordset
Set wkSpace = DBEngine.Workspaces(0)

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 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...
