Hi,
I've made a small utility to re-raise an exception with the same stack
as before with additional information in it. Since I want to keep the
same exception type and that some types have very specific constructors
(which take, for example, more than one parameter), the only safe way I
have found to made it is by hacking the str representation:
import sys

I just found out by accident, that slice indices can be larger than
the length of the object. For example
>>> 'test'
'test'
>>> 'test'
''
I'd rather expected to be confronted with an IndexError.
(This is actually described in
http://docs.python.org/lib/typesseq.html, so my expectation was wrong :))

I have an MDI application that was occasionally refusing to close. When clicking on the cross at the top right the app would just
not do anything and the only way to close it was to terminate it. The problem ended up being that in the Form_Closing event had
e.Cancel = True even though I've not set it to true (it took a while to find because it only ever happened once in the IDE). Setting
it to false fixed the problem. I've done a fair bit of...

Hi,
I am developing a WinForm application and I am looking for a guide on where
to place Exception Handling. My application is designed into three tiers
UI, Business Objects, and Data Access Layer. My questions is where should I
put exception handling:
1) Should it be put in all significant methods in all layers?
2) Should I create an exception base class that will handle the errors and
pass useful error messages to the user?

I was curious if there is some reason why you don't need the "then" in the
if test of VB.Net or is it just ASP.NET.
I just noticed that I don't really need to explicitly put the word "then" as
part of my if statement.
For example:
if a = b
b= 10

I wrote a program that shows some incredibly curious probabilities. It
is a simple game where you guess a number between 0 and 2 that the
computer thinks up. What is origonal about this game is the computer
tells you before hand if you got the number right and you can decide if
you want to play or not. The computer keeps track of all your wins,
all your losses, and as is possible all of your didn't wins but didn't
loses. What is...

Am I nuts? Or only profoundly confused? I expected the this little script
to print "0":
class foo(int):
def __init__(self, value):
self = value & 0xF
print foo(0x10)
Instead, it prints "16" (at least on python 2.4.4 (Linux) and 2.5 (Wine).

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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...
