I have a website with an increasing amount of articles and news reports and
so I am thinking of moving away from storing each article as a seperate page
to having a single page and storing articles in a databasewhich are
retrieved using a GET parameter.
I see the advantage to me in using this approach as being making use of
MySQL's fulltext search capability and less work needed when updating the
design of the page. I'm not sure of a few...

Hi,
My latest web project includes loads of user-customisable features,
lots of which are on/off values. Currently I'm storing each one of the
15 or so properties in tinyint fields, as 1s or 0s. There must be a
smarter way...
I know it's possible to store a set of 8 bits in a tinyint column, but
the work involved in retrieving, and (more importantly) updating the
flags is off-putting. I had a look at the set field type, but can't
find...

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.

Hi, All
I am reading FAQ of this group. I have a question about this:
http://www.eskimo.com/~scs/C-faq/q7.31.html
It says:
"
p = malloc(m * n);
memset(p, 0, m * n);
The zero fill is all-bits-zero, and does not therefore guarantee useful null
pointer values (see section 5 of this list) or floating-point zero values.

How i can store a variable length data in file ?
I want to do it using pure C, without existing databases.
I'm thinking to use pages to store data.
Anyone has idea for the file format ?

Hi there,
union UC32 {
unsigned int L;
unsigned short S;
unsigned char C;
} UC32;
with the above structure, I am able to shift bits of C, into C,
and C into C so on and so forth till C as they are "union"ed

What would give better performance, serializing a multidimensional array
and storing it in a single entry in a table or storing each element of
the array in a separate table and associating the entries with the entry
in the other table?
Having a separate table would result in two queries instead of one, but
you wouldn't have to deal with the overhead of serializing and
unserializing data.

Hi all,
I want to write a program to count number of bits set in a number.
The condition is we should not loop through each bit to find whether
its set or not.
Thanks in advance,

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...

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...

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...
