Hello,
I am creating a databse with a large number of text (or blob?)
entries. I want users to be able to search these fields.
An example would be a forum or journal. Indexing every word in the
post seems costly. If I have 100,000 posts over a few months, and each
one has 50 words in it, that is a 500,000 match entries. The databse I
will be creating will be even larger. For longer posts, there is a
huge overhead of dozens of INSERT...

Sites using thumbnail preview for world wide web file navigation and
searching.
Below are list of sites that are either researching or providing thumbnail
preview images for online web documents. Thumbnail previews are useful for
web site navigation particularly in search engines and directories such as
Google, Altavista and Yahoo. The preview images provide a portion of the
content of the electronic file to aid in navigation.

Hi there.
I have defined a class called Item with several (about 30 I think)
different attributes (is that the right word in this context?). An
abbreviated example of the code for this is:
class Item(object):
def __init__(self, height, length, function):
params = locals()

Hiya
I have a DataTable containing thousands of records. Each record has a
primary key field called "ID" and another field called "PRODUCT" I want to
retrieve the rows that satisy the following criteria:
I have a list of about 100 numbers which correspond to the ID field and also
another 40 say numbers corresponding to the numbers in the PRODUCT field. I
want to show the rows that correspond to both these criteria.

I would like to write a C++ program that searches for the variable "state !=
0" in a text file, and then go back 3 steps each time to read "count". The
program should create a new file with "state count". The data in the old
file is variable, but could be as follows:
old_file.txt
new_file.txt
state count
state count
0 22

Hi.
I am somewhat new to this and would like some advice.
I want to search my xml file using "keyword" search and
return results based on "proximity matching" - in other words,
since the search string will often not produce a direct match,
the results will be based on proximity (50%, 20% 100%, etc).
are there any good examples out there on how to do keyword
searches on XML data? How should i set up my xml file so

Hi
I have a binary file which contains records sorted by Identifiers
which are strings. The Identifiers are stored in ascending order. I
would have to write a routine to give the record given the Identifier.
The logical way would be to read the record once and put it in an STL
container such as vector and then use lower_bound to search for a
given identifier. But for some strange reason i'm asked to not use a
container but instead...

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...

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...
