I have to read and process a large ASCII file containing a mesh : a
list of points and triangles.
The file is 100 MBytes.
I first tried to do it in memory but I think I am running out of
memory therefore I decide to use the shelve
module to store my points and elements on disks.
Despite the fact it is slow ... Any hint ? I think I have the same
memory problem but I don't understand why
since my aPoint should be removed by the gc.

I've been thinking about writing a program to generate the world's
largest prime numbers, just for the fun of it. This would require being
able to hold an 8000000 digit number into memory (25 megabits, or a
little over 3 megs of memory for just one variable...) I would also
need several smaller variables. This came about as I optimised a prime
number generator more and more, until I came with the idea to try to
find the largest ever, using...

Well, I'm stuck in legacy land and I need a helping hand.
We're trying to give some modern value-added functionality to
a circa-1985 fortran proggie.
The program produces a binary file, by itself no problem...
each record needs to be converted into std::vector<mystruct>
I'm having a helluva time with the binary-->(pod)datatype conversion.

Hi,
I have a number which is larger than the max unsigned long int. I
don't have 64-bit integers available to me. I need to get the
resulting 40-bit hex string.
I can't find any algorithm or solution when I search the web. I've
seen a couple of suggestions searching Usenet, but neither of them
works. One tried to use a union, and the other tried to convert each
byte of the float.

Hello,
I'm struggling with the string conversion to MD5 which I've never user
before.
I have a string that I need to encode which looks approximately like this:

Hi,
Apologies first as I am not a unicode expert.... indeed I the details
probably totally elude me. Not withstanding: how can I convert a
binary string containing UTF-8 binary into a python unicode string?
cutdown example:
$ cat ./uc.py
#!/usr/bin/env python
imported="\304\246\311\231\316\257\316\271\303\222

Hi,
I have working on a system in which I have to manipulate *very* big numbers.
Like
32368060745625089670148189374568111100874165870871388541651800834565616109380834613212956588769877
They may be upto 10000 digits long.
These numbers are coming through a device in ascii format, I am creating a
text file and saving these numbers in the file.

Hi
I'm maintaining a VisualC++ project to increase its security regarding
stored passwords.
I thought about using SHA256Managed to create a hash for the password
when creating a user and when this new user tries to login, a new hash
will be created for the given password and compared to the stored
hash. I guess this is quite common.

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...

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 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...
