Hello,
I tried to read in some large ascii files (200MB-2GB) in Python using
scipy.io.read_array, but it did not work as I expected. The whole idea
was to find a fast Python routine to read in arbitrary ascii files, to
replace Yorick (which I use right now and which is really fast, but not
as general as Python). The problem with scipy.io.read_array was, that it
is really slow, returns errors when trying to process large files and it...

I feel stupid for asking this but I can't figure this out. I've got some
text files I want my website to read. The text files are located in a
subdirectory of my application. Physically, the files are located on drive
C: in directory starting with InetPub/myapplication/directrory/files .
Thing is,when the website is running, the application path is
c:\windows\system32. I can manipulate the path to get this to work for now.

I have some UTF-8 text files written in Chinese to be read. Now the
only method that I know to read text from it is to use fopen()
function. Thus, I must read the contents byte by byte, change the UTF-8
characters to Unicode, store the characters into wchar_t variables. But
I think this method is too complex and isn't elegant at all.
Are there any ways to read the UTF-8 text files as simple and
convenient as the way that we read ANSI...

Hi,
I'm trying to open a file (any file) in binary mode and save it inside
a new text file.
After that I want to read the source from the text file and save it
back to the disk with its original form. The problem is tha the binary
source that I extract from the text file seems to be diferent from the
source I saved. Here is my code:
1)
handle=file('image.gif','rb')

Hi,
Is it possible to read a file in reverse and only get the last 100 bytes in
the file without reading the whole file from the begining? I have to get info
from files that are in the last 100 bytes of the file and some of these files
are 600Mb -1 GB in size. I am getting "outofMemory.." exceptions on the
largest files and the other files take "forever" to get the last 100 bytes.
This is the code I have currently that works with...

I'm looking for something that can read .MDB files, the format
Microsoft Access uses, from Python. I need to do this on
Linux, without using Microsoft tools. I just need to read
the files once, so I can load the tables into another database.
Speed isn't an issue, and I don't need to access the file in
database fashion. The files are too big to read into RAM all at once,
though.
I tried "MDBtools", but the only (last) release was

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

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....

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...
