Hi,
we have some major GC issues at present with a system we're trying to
put live. It's a live calculation engine that's distributed across
about 30 Java server processes. A set of processes called
objectservers sit between the core infra and a Sybase DB. Two of the
main objectservers are set up with 2Gb Heaps as they need to cache
large amounts of objects and accept 500-600 incoming RMI connections
when heavily loaded. We're running the...

Hello,
I couldn't find an obvious answer to this in the FAQ. My basic question,
is: Is there any difference in allocating on the heap versus the stack? If
heap or stack implementation is not part of the standard, then just
disregard this question. Here's some questions I'm confused about, and if
you can add anything else, please do so!
Is the stack limited for each program?

I had an interview today and I got destroyed :(
The question was why have a stack and a heap?
I could answer all the practical stuff like value types live on the
stack, enums are on the stack, as are structs, where classes are on
the heap... when value types go out of scope the memory is re-
allocated, object remain in memory waiting to be cleaned up by the
garbage collector, etc, but he responded 'so why not just put say a
class on the...

This is an interview question and I gave out my answer here, could you
please check for me?
Q. What are the memory allocation for static variable in a function,
an automatic variable and global variable?
My answer: static variable in function and global variable are
allocated in head, and automatic variable is allocated in stack.
Right?

Greetings,
I was asked to write a Tip Of the Week; so here goes: a lot of topics are
started here in this forum (and a lot of other forums too) mentioning a
problem about sorting data.
Examples of two main problem scenarios are like this:
1) an array containing a first name and another array containing a last name
and possibly a third array containing the age of a person; how to sort the

Hello,
I'm confused about heap and stack memories management in C language. Most
books explain that local stack variables for each function are automatically
allocated when function starts and deallocated when it exits. In contrast,
malloc() always takes memory in the heap. Now, let's consider the code as
follows:
int get_buffer()

Hi guys,
For last few days we are getting out of private memory error. We have a
development environment. We tried to figure out the problem but we
believe that it might be related to the OS (I am new to Windows so not
sure). We are currently bouncing the instance to overcome this error. This
generally happen at the end of business day only (So maybe memory
might be getting used up?). We have already increased the statement heap &

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.
First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

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,...

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...
