I'm using PHP 4.2.2 on RH9 Linux (with Progeny.com updates, in case
you're wondering). I was using shared memory (shm* API) a great deal
in my web applications because I have 1GB of RAM on this system. By
using shared memory, I can optimize web pages a little by not having
to hit the database every time I want to regurgitate a somewhat-static
reference table.
You may be familiar with the API that looks like this:
$key = 'My Key';

I would like to start a dialog on how to implement the equivalent
functionality of UNIX shared memory in .NET. I work with a factory
automation system. The bulk of the system is written in C/C++. It was
ported from UNIX to run under Windows using .NET. If for no other reason
than as an educational exercise, I have been wondering what it would take to
rewrite the system under C#.
The system currently has about a 100K “shared...

Dear C++ Experts,
Over the last couple of months I have been writing my first program
using shared memory. It has been something of an "in-at-the-deep-end"
experience, to say the least. At present the shared memory contains a
few fixed-size structs, but I really need to be able to store more
complex variable-sized data in there. So the next task is to work out
how to store C++ objects, and if possible STL containers, in this
shared...

Hi all,
I'm getting very confused about how DB2 uses shared memory and I
wonder if someone could clarify matters for me, please ?
We are running 32bit DB2 V7.2 FP9 under AIX 4.3.3 on a machine with 64
Gb of memory with a single non-partitioned database using extended
storage and with intra-parallelism enabled.
I've been experimenting with changing various parameters in an attempt

Hello,
I want my python application to communicate with an legacy C program which
read/write data in a shared memory (Unix Sys V IPC).
It seems that there are no official shm nor sysV ipc module, and that
non-official ones are dead. I can't modify the C code to change its
communication method.
How would you solve this problem using python ?

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:

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,...
