Peter Norvig's creative thinking triggered renewed interest in PEP 289.
That led to a number of contributors helping to re-work the pep details
into a form that has been well received on the python-dev list:
http://www.python.org/peps/pep-0289.html
In brief, the PEP proposes a list comprehension style syntax for
creating fast, memory efficient generator expressions on the fly:
sum(x*x for x in roots)

I'm working on the 0.8 release of my 'rex' module, and would appreciate
feedback, suggestions, and criticism as I work towards finalizing the
API and feature sets. rex is a module intended to make regular expressions
easier to create and use (and in my experience as a regular expression
user, it makes them MUCH easier to create and use.)
I'm still working on formal documentation, and in any case, such
documentation isn't necessarily the...

I was wondering if anyone could tell be whether it's possible to
instruct preg_match not to save subexpressions matches under 0, 1...n
keys when using named subexpressions; I.e instruct preg_named to
matched under their names only,
and not under their numbers. E.g. take the following example:

Hi,
I have several regular expressions that I need to run against
documents. Is it possible to combine several expressions in one
expression in Regex object. So that it is faster, or will I have to
use all the expressions seperately?
Here are my regular expressions that check for valid email address and

Hi All,
I'd like to "compress" the following two filter expressions into one -
assuming that it makes sense regarding query execution performance.
.... where (adate LIKE "2004.01.10 __:30" or adate LIKE "2004.01.10 __:15")
....
into something like this:
.... where adate LIKE "2004.01.10 __:(30/15)" ...

I have a dynamic list of regular expressions, the expressions don't change
very often but they can change. And I have a single string that I want to
match the regular expressions against and find the first regular expression
that matches the string.
I've gor the regular expressions ordered so that the highest priority is
first (if two or more regular expressions match the string I want the first
one returned)
The code that does this has...

There has been a discussion on the iPhone web development group where
an opinion has been expressed that function expressions are bad for
performance and can be avoided by using function declarations.
For example (in a trivial case, the function body would do processing
depending on various parameters passed) instead of:
function foo(x) {
var a = function(){x};
return a;

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...
