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 need to access large files > 2GByte (Linux, WinXP/NTFS)
using the standard C-library calls.
Till today I thought I know how to do it, namely for
Win32:
Use open(), read(), _itelli64(), _lseeki64() with type __int64
Linux/Cygwin:
#define _FILE_OFFSET_BITS 64
Use open(), read(), lseek() with type off_t

Hi all,
I'm trying to read from the txt file 'ip.packets.2.txt' using the read
function. It seems everything ok, but I get a -1 when executing
>>bytesr = read(fdo1, bufread, 2);
The 'open' function returns the file dsc 3. So this seems ok..
Any idea what might be wrong?

I have a FileStream retrieved from FileOpenDialog. I have a Byte which I
intend to store for later use. What is the most efficient way of getting
the File into my Byte and tehn back out to a new FileStream ? I have been
looking at all the Readers and Writers and due to information overload
cannot decide on the proper method.
Thanks,
JIM

Wrote a little "user-friedly" wrapper for ConfigParser for a KDE's
SuperKaramba widget.
(http://www.kde-look.org/content/show.php?content=32185)
I was using 2.4.x python docs as reference and
ConfigParser.read('non-existent-filename') returns in 2.4.x
One user with 2.3.x reported an error stemming from my use of
len(cfgObject.read('potentially-non-existent-filename'))

Hi all,
I've developed a mobile application for windows mobile 5.0 that has been in use for a while (1 year and a couple of months). It was developed in visual studios 2005 with a back-end sql server mobile ce database. Until recently I was synching everything thru a com port serial cable. The devices would connect to the computer thru activesync and are able to acquire an internet connection. The sync for the program occurs thru a website...

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...
