I just compiled (but did not install) perl 5.8.0 on an SGI Origin 300
server (IP35) running IRIX 6.5.20m.
Make test reported one test error, which I narrowed down to
.../lib/ExUtils/t/Constant.t using harness. I ran the test separately,
and got the following detailed error report:
.../lib/ExtUtils/t/Constant....ok 6/51Confused test output: test 6
answered after

Hi Pythonians,
To begin with I'd like to apologize that I am not very experienced
Python programmer so please forgive me if the following text does not
make any sense.
I have been missing constants in Python language. There are some
workarounds available, for example the const-module. To me, this looks
quite cumbersome and very unintuitive. For the interpreter, in the
efficiency-wise, I just cannot tell.

Hi,
I'm trying to compare an array of unsigned chars(basically just data
without any context) with a constant, and I'm not sure how to do that.
Say my array is array and I want to compare it with the constant
0x00010203040506070809 where array == 0x00, array == 0x01, etc.
How do I do that. Obviously I can't use memcmp() with the
0x00010203040506070809 since the compiler will use that constant as an
address and give me a segfault. Other...

In the C++ standard sec 23.1.2 table 69 it says that erase(q) where q is
a pointer to an element can be done in amortized constant time.
I guess that is not worst case since std::set is practically a red-black
tree where insert/delete takes O(lg n) time. Or are there some other
explanation for this complexity?

Hi all,
I'm porting some code that provides compile-time assertions from one
compiler to another and ran across what I believe to be compliant code
that won't compile using the new compiler. Not naming names here to
remove bias - I'm trying to tell if I'm relying on implementation defined
behavior or if this is a bug in the new compiler.
Consider this stripped down example:

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...

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...
