I have a list of dictionaries. Each dictionary holds counts of various
'words', e.g.:

I need to select dicts with the constraint that the number of each
'word' totalled over all selected dicts doesn't exceed a given
MAX_VALUE. Right now, I do this by:

Hi,
I have many set objects some of which can contain same group of object
while others can be subset of the other. Given a list of sets,
I need to get a list of unique sets such that non of the set is an
subset of another or contain exactly the same members.
Tried to do the following:
s1=set()
s2=set()
s3=set()

I searched around on the net for a bit, couldn't find anything though.
I would like to find some code for a function where I input A Range Of
Integers
For example: Function( 1, 100 );
And the function will return me an array holding a random subset of integers
in that range of a size that I specify
So the Function would Probabaly look something like this:

Hello all,
I have a class that contains a large number of discrete pieces of state
information. Any combination of these member variables might be valid for a
given object. Any given member variable might be used or unused in a given
object. For each field, there is a FieldIsValid() member function that must
be called before accessing or mutating a given field. If a field is
reported as not valid, it must not be accessed or mutated....

I am looking for other people's attempts to create safe subset of C and
enforce it with scripts. Does anybody know about anything like this?
By "safe", I mean the following:
* Strongly typed memory. No way to reinterpret it as bunch of bytes
* Recovery from invalid and NULL pointers other than crash
* Possibility to isolate piece of code by not giving it key pointers
Library used to support such safe subset must not introduce its own...

Dear Group,
I have a heirarchical set of database tables, say - "order" and "order_type"
and want to display a series of orders in a grid control, and in place of
the order_type foreign key identifier, I would like a dropdown combo box
(lookup from the "order_type" table) to change the type of the order. I also
need an update command button, a delete row button and also an insert new
row button.
I'm sure this is a very common design...

Greetings,
I have to load 30,000 unique names into a combox. Filling a dataTable takes
only a few milliseconds. But populating the combobox and displaying the list
takes several seconds - way too long. A user selects a name from the
combobox and runs a query.
Originally, this combox was on a form in an MS Access ADP which was linked
directly to our sql server. The combobox populated withins millisecnods.
How can I achieve this...

Hi
I would like to write a SQL select statement that would fetch rows
numbered 50 to 100.
Let me clarify, if i say "fetch first 10 rows only", it returns the
first 10 rows from the resultset. how do I get a specific subset of
rows from the result set if I give a start and end value. For example,
retreiving rows 50 to 100 from the resultset.

From my business tier (class) I get back an IQueryable<Penof data. Here
is my client code that works fine:
PenClass penClass = new PenClass();
IQueryable<Penpens = penClass.SelectPens();
However, I want to then select a subset of this data from within the client.
I tried this:
IQueryable<PenpensSubset = from p in pens select p.PenId, p.PenNumber;

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...
