Beside its an opensource and supported by community, what's the fundamental
differences between PostgreSQL and those high-price commercial database (and
some are bloated such as Oracle) from software giant such as Microsoft SQL
Server, Oracle, and Sybase?
Is PostgreSQL reliable enough to be used for high-end commercial
application? Thanks

I'm having problems with a program I wrote- when it comes time to output
a file, the call to fopen locks up and I have to break the program
manually. I've pinpointed the actual stopping point to fopen, but due
to my lack of knowledge with gdb, etc., I don't know how to go any
further with the debugging from there.
I'm running gcc under cygwin. Sorry for the lack of information.
Here's the code in question, please no comments on...

I am trying to get multiple threads to lock specific regions of a file.
However, since each thread has the same PID, it appears that a lock by
one thread does not block another thread from the same process.
How does one maintain file locking between sibling threads?

I have a global.asax file with Application_Start defined and create some
static data there and in another module used in the asp.net application and
I realize that static data is shared amongst child apps of an IIS
application and can be used by multiple users during the application life
cycle and for multiple page loads for the same or different page under a
root application.
What I don't understand and need to know is whether that...

Hello! I am writing some software that will have many users accessing
the same file resource at once for reading purposes only. I am
programming on (Ubuntu) Linux and my question is in Windows, can I
have it so that the same file can be open in read mode by more than
one person or could Window's file locking system get in the way?
Thanks,

SUBJECT: How to make this program more efficient?
In my program, a thread will check update from server periodically and
generate a stl::map for other part of this program to read data from.
Let's name the update method as doUpdate and stl::map read methods as
getData and copyData.
Since stl::map is not thread-safe, we should do synchronization by
ourselves. A usable solution is to create a boost::mutex::scoped_lock
object in all above...

Hello
I see there is now why to truncate a file (in C or C++)
and that I have to use platform-specific functions for
truncating files.
Anyone knows why ? I mean C/C++ evolved over many years now,
and still, people making _the_ standards never decided to
include such a function. Even in POSIX it was included only
in recent versions, mostly not fully supported yet.

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
