In this snippet:
d = {'x': 1}
value = d.get('x', bigscaryfunction())
the bigscaryfunction is always called, even though 'x' is a valid key.
Is there a "short-circuit" version of get that doesn't evaluate the
second argument if the first is a valid key? For now I'll code around
it, but this behavior surprised me a bit...

Is there a way to generate a listing of some/all of the "field descriptors"
for an ACCESS table?
I am a SAS user and am looking for something like SAS's proc CONTENTS which
generates a basic "data dictionary" on a SAS dataset.
Is there something like this 'built into' MS-ACCESS?
Thanks.

I've got some data that has Set structure, that is membership, insert
and delete is fast (O(1), hashing). I can't find a System.Collections
interface that matches the operations naturally offered by Sets.
- ICollection cannot decide containment
- IList promises indexability by the natural numbers, which is not
achievable (since i hash elements, not sort them).
- IDictionary is definatly not setlike.
Although I can, of course, define...

Hi all.
I'm a newbie and I am reading "Programming in the Key of C#" by Charles
Petzold. I am getting an idea of how C# works and writing a "Hangman"
program just for the fun it. But, I am in need of a way to get (randomly) at
the dictionary (MS Word?) to find words. Can this be down?

I'm a linguist and have a large self-built bilingual dictionary. I want to
turn it into a electronic dictionary, can anyone tell me how to start with

What is the best way to handle updates in databases with each release
of a software package? I used to work on an accounting package in
FoxPro that had a "Data Dictionary" and as your code required changes
to the database per release, you'd update the Data Dictionary.
When you wanted to create a new database, it would create it
completely from the data dictionary. If you already had a functional
database and the new release required...

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...

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...
