Hello, I've just written a CPP program that reads integers from a
binary file, and used this code
while (my_ifstram.read( (char* ) &number, sizeof(int))
{
// do something with number
}
My question is now, where can I find a manual that describes what
the read method does with the ifstream object?
I'm sitting here with my Linux/Debian machine, but I have not found any

I have a question about oracle commit and transactions. Following scenario:
Process A performs a single sql-INSERT into a table and commits the
transaction. Then he informs process B (ipc) to read the new date. So
process B starts "select ..." but does not get the previously inserted
row. The timespan between commit and select is very short.
(NOTE: two different sessions are used)
Questions:
1.) Does commit when returning from call...

I know of a least one person who believes std::ifstream::read() and
std::ofstream::write() are "mistakes". They seem to do the job I want
done. What's wrong with them. This is the code I currently have as a test
for using std::ifstream::read(). Is there anything wrong with the way I'm
getting the file?

#include <iomanip>

Just looking for suggestion on how to do this in my Web application.
The goal is to keep track of what a user has and hasn't read and present him or
her with new material
I am currently doing this by aggregating new content from all databases into a
single indexed database and then saving a timestamp in the account database
(for the current user) that tells me when the user last read items in the
aggregated database.

Hi,
I am having some difficulty with read(2) and interrupting signals. I
expect I am misunderstanding how the two work together, so would
appreciate some guidance.
I am trying to 'time out' a socket read after a certain delay. The logic
is (I will provide a test program below):
- create and connect socket

I have an object that has a fairly complex construction sequence, so I have
written a dedicated "factory" class that invokes the constructor of my object
class (which does nothing but instantiate the object and set default
blank/null values), and then does all the Db access and number crunching to
populate the new object. The factory returns the fully populated object to
the caller. All the fields in the object are private, but have...

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...
