Hello All!
I am new to Python, and wanted to know if I might ask you a question
regarding timing.
I want a main loop which takes photos from 8 different web-cams, each can
be addressed by http://ip-addr/image.jpg. That's the easy part, but I want
to have 2 cameras poll 3-times a second, 4 cameras poll 2 times a second,
and the remaining 2 cameras poll once a second. I have found lots of info
suggesting the use of threads for this, all...

When content is transferred from a hidden IFRAME (which has fetched data
from a database) to a DIV in the main document, how can a script determine
that the DIV has been completely populated before it acts upon the data?

myDIV.insertAdjacentHTML("afterBegin",
myIFRAME.window.document.getElementById('data') )

// convert text in myDIV to uppercase

This query is odd, it seems to be taking over a second according to my
log_duration logs and according to psql's \timing numbers. However explain
analyze says it's running in about a third of a second.
What would cause this? Is it some kind of postgresql.conf configuration
failure? I have the same query running fine on a different machine.

How long do Session variables last before timing out? What is the default

Hi there.
This looks like a good place to get help with a problem I am having:
- We have a c# windows app, which performs an HTTPWebRequest to a IIS box on
Internet to retrieve an XML response.
- In our test + develop environment this works wonderfully. We have it
working through ISA server and also without ISA server.
- At our client site however, the application times out. This appears to be
caused by Keep Alives.

The timeit module is ideal for measuring small code snippets; I want to
measure large function objects.
Because the timeit module takes the code snippet argument as a string, it
is quite handy to use from the command line, but it is less convenient for
timing large pieces of code or when working in the interactive
interpreter. E.g. variations on this *don't* work:

I have a multi threaded VB.NET application (4 threads) that I use to send
text messages to many, many employees via system.timer at a 5 second
interval. Basically, I look in a SQL table (queue) to determine who needs
to receive the text message then send the message to the address. Only
problem is, the employee may receive up to 4 of the same messages because
each thread gets the recors then sends the message. I need somehow to
prevent...

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,...

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...
