Having recently load-tested the application we are developing I noticed that
one of the most expensive (time-wise) calls was my fetch of a db-connection
from the defined db-pool. At present I fetch my connections using :
private Connection getConnection() throws SQLException {
try {
Context jndiCntx = new InitialContext();
DataSource ds =

Hi everyone,
I have to make a (case-insensitive) search from a form with only one
search string,
e.g. "Doe Peters english California",
which will search in several fields of my table for each word.
My fields that are searchable by this query are:
nr smallint(5)
company varchar(100)
lastname(100)

Hi all,
Wanted to know what is the most efficient way of doing a select query
for mysql that only returns one value. For example:
$mysqli->query('select count(*) from log');
$temprec = $result->fetch_assoc();
$count = $temprec;
That doesn't seem efficient. How should I do it? Or is this as efficient

Hi
I need a time and space efficient way of storing up to 6 million bits. Time
efficency is more important then space efficency as I'm going to do searches
through the bit-set.

What is the most efficient way to scan an array for a match ? I could just
iterate directly through it comparing each array entry with what I am
looking for, I could use an enumerator to do the same thing (though I dont
know if this is better), I could convert the array to some other structure
which makes direct lookup possible (if I want to do the same thing many
times), or maybe some other entirely different approach is better. Any
ideas?

Hi,
I need to store literally thousands if images and scanned document in the Database. I would like to know what is the most efficient algorithm both in terms of speed and storage for saving images in database (using SQL server).
Currently I am using the following algorithms. Question is can I improve this?
'Get length of stream (lengt of file) in bytes
InByteCount = loFile.Length()

Using .NET 2.0 is it more efficient to copy files to a single folder versus
spreading them across multiple folders.
For instance if we have 100,000 files to be copied,
Do we copy all of them to a single folder called 'All Files'
Do we spread them out and copy them to multiple folders like
Folder 000 - Copy files from 0 to 1000
Folder 001 - Copy files from 1000 to 2000
Folder 002 - Copy files from 2000 to 2999

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...

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...
