I'm trying to write a simple python program to access a MySQL
database. I'm having a problem with using MySQLdb to get the results
of a SQL command in a cursor. Sometimes the cursor.execute works,
sometimes not.
From mysql:
mysql> show databases;

Hi All,
Given the following XML, I've been trying to figure out what XPATH
expression will give me the "position" of a <lineitem> within the
<shipto> that is its grandparent.
To give you an idea of what I'm trying to do...I'm transforming this
XML into XSL-FO; which I will process with FOP to produce a PDF file.
Each <shipto> element with the XML correlates to a new "section"

Hi All,
I am writing a .NET app that accesses an access View. The view has a table
column called 'Position'. When i try and right an UpdateCommand string for
this using this column I am greeted with a 'Syntax error in Update
statement.' when attempting the update. I take that field out and the update
works. I am assuming Position is a reserved word. I have even tried
changing the name of the column in the View to something other...

I write below code in my program:
float f=0.371f;
int i=(int)(f*1000.0f);
I think the result of "i" should be "371",but in fact it is "370",why?How to solve it?

I'm investigating a puzzling problem involving an attempt to generate a
constant containing an (IEEE 754) "infinity" value. (I understand that
special float values are a "platform-dependent accident" etc...)
The issue appears possibly to point to a bug in the Python compiler,
with it producing inconsistent results. I'm using "Python 2.4.2 (#67,
Sep 28 2005, 12:41:11) on win32".
This code sometimes produces a float of 1.0, sometimes...

As far as I know floating point variables, that are declared as float
follow IEEE format representation (which is 32-bit in size). But
chapter1-page no 9 of the book "The C programming language" states that
"THE RANGE OF BOTH int AND float DEPENDS ON THE MACHINE YOU ARE
USING".
Does this mean "float" variables have different sizes on different
machines?

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...
