The facts:
PostgreSQL 7.4.0 running on BSD 5.1 on Dell 2650 with 4GB RAM, 5 SCSI
drives in hardware RAID 0 configuration. Database size with indexes is
currently 122GB. Schema for the table in question is at the end of this
email. The DB has been vacuumed full and analyzed. Between 8 and 12
million records are added to the table in question each night. An
analyze on the entire DB is done after the data has been loaded...

I've been trying to understand the article "Identifying Memory Leaks in
the Common Language Runtime" listed on http://support.microsoft.com/?id=318263
It says "The garbage collector can
collect and free the memory but never returns it to the operating system.
This occurs when the garbage collector cannot move the objects that are
still in use to one portion of the memory and free the rest."
How can this happen? I know the basics of...

I have a long but straightforward query (on some very large tables)
that always ends in 'Memory exhausted in AllocSetAlloc(108)'. Even
stranger are some messages that appear in the logfile, such as the
following (edited for length, repetitions, etc):
TopMemoryContext: 32792 total in 4 blocks; 9712 free (2 chunks); 23080 used
TopTransactionContext: 8192 total in 1 blocks; 8176 free (0 chunks); 16 used

To all,
Running into an out of memory error on our data warehouse server. This
occurs only with our data from the 'September' section of a large fact
table. The exact same query running over data from August or any prior
month for that matter works fine which is why this is so weird. Note that
June 2004 through today is stored in the same f_pageviews table.
Nothing has changed on the server in the last couple of months. I upgraded...

Our developers have experienced a problem with updating Web References in
Visual Studio.NET 2003.
Normally, when a web service class (.asmx) is created, updating the Web
Reference will utilise the disco file to update the
Corresponding proxy file and reflect the changes made to the web service.
However, the results of doing this with out params is that the results seem

Let's assume I have following file:
2938929384902491233.....
923949919199191919112....
File contains INTs only. What is more they are huge. For example first
row in file may contain integer which size is 50MB and the second 30MB.
Now we come to my problem. Is there possibility to swap this rows
without using system memory (preferably in Unix/Linux)? Is there any
function in C to do this?

Hi
I have a JS program that runs localy (under IE6 only) on a PC but it has
a memory leak (probably the known MS one!)
What applications are there that I could use to look at the memory usage of
each object within my JS app to help locate my problem?
Thanks

My pet project is a command-line utility (preprocessor), so it runs and
terminates. It uses lots of memory allocations; most of them are quite
small. What to do with the allocated objects when they are no longer
used? I consider the following "pure" strategies:
- Meticulously free anything ever malloc'ed. This involves
inefficiencies of calling free, but worse yet, in certain cases object
duplication appears necessary to ensure uniqueness...

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
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
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...
