I have a requirement where I have to use two unsigned ints as a key in a STL
hash map.
A couple of ways to do this is
1. create a struct with two unsigned ints and use that as key (write my own
HashFcn and EqualKey template args) or,
2. convert the two unsigned ints to char*s, concatenate them and use that as
Key.
For method 1, the difficulty I am having is in writing the HashFcn. HashFcn
requires the following method

Hello,
I am using some very large dictionaries with keys that are long strings
(urls). For a large dictionary these keys start to take up a
significant amount of memory. I do not need access to these keys -- I
only need to be able to retrieve the value associated with a certain
key, so I do not want to have the keys stored in memory. Could I just
hash() the url strings first and use the resulting integer as the key?
I think what I'm...

Hi all,
I've ported various hash functions to python if anyone is interested:
def RSHash(key):
a = 378551
b = 63689
hash = 0

I would be grateful if someone had a minute or two to review my hash
table implementation. It's not yet commented but hopefully it's short
and idiomatic enough to be readable. Some of the code (i.e. the
get_hash function) is borrowed from various snippets I found on the
net. Thee free function could probably need some love. I have been
thinking about having a second linked list of all entries so that the
cost of freeing is in proportion to...

Dear all,
I am new to Perl.
I have a large matrix. The easiest way to describe is it is like a calender where there are days along the top, numbers of weeks down the side, and the numbers of dates in the rest of the table.
Imagine this calendar to be populated with different data but with the same concept, but more like 10,000s across and 10,000s down. How would I parse this huge dataset into a hash. I know how to do the smaller...

A quick sanity check, and I think I am correct, but just to make
sure: if you have a bunch of objects that are very much like one
another you can uniquely track them simply by using an ArrayList or
Array, correct? An example: create the object, create an array, the
stuff the object into the array. Later on, assume the object is
mutable, the object changes, but you can find it, if you have enough
state information to uniquely identify...

I have a file that has is pipe delimited with 374 fields per line and 7.500 plus lines per file. I have about five of these files. I need to get this into a database and did not want to do it manually, Preserving the order is crucial. I am using Tie::Hash::Indexed to keep the order.

Good Morning!
I am a perl newbie and I think that I am struggling with references.
I have an array of references to hashes which I am trying to print. This is what I have:
for(my $i=0; $i<@input; $i++){
my $hash = $input;
print "$i: \n";

INTRODUCTION
The Secure Hash Algorithm 2 is a series of cryptographic hash algorithms designed by the US National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) as a government standard.
There is currently a competition being held by NIST to find a new family of algorithms for what will be named SHA-3. These new functions may not necessarily be derived from the SHA-2 algorithms.
One of the...

Overview:
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,...

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...
