From MSDN dox:
WinSock select():
For connection-oriented sockets, readability can also indicate that a
request to close the socket has been received from the peer. If the
virtual circuit was closed gracefully, and all data was received, then a
recv will return immediately with zero bytes read.
..NET Socket.Select():
Readability can also indicate whether the remote Socket has shut down

Is it safe to call socket.BeginSendTo and socket.BeginSendFrom on a
single instance of Socket from two different threads running
simultaneously?
This is required because I need to listen on a certain URI and
I need to send outgoing messages from that local socket
something like this:

in March, i posted a essay “What is Expressiveness in a Computer
Language”, archived at:
http://xahlee.org/perl-python/what_is_expresiveness.html
I was informed then that there is a academic paper written on this
subject.
On the Expressive Power of Programming Languages, by Matthias
Felleisen, 1990.

Here are three network-related exceptions. These
were caught by "except" with no exception type, because
none of the more specific exceptions matched. This
is what a traceback produced:

data = self._sock.recv(recv_size)

Hello,
I have a report that I open that pull its data from a form that builds a where string. Opening the report first opens the form, where I enter criteria, and then pulls matching records from a table, opens the report, and closes the form. The code on the report is below.
I used this code on a similar report that also pulled its data from a form (the difference was that that form supplied criteria to an actual query - my new form...

I'm not sure if you need to write a server or a client. In your

The basic version is pretty easy either way. However, with Twisted,
you get cross-platform error handling without any extra effort, and
you don't have to think about the...

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...
