I'm playing with some image algorithms and one of the examples discusses
fingerprint comparison.
The NIST has fingerprint sample files for download, in NIST IHead
format. Has anyone built a reader for that format?
Thanks

Hello Charles,
I am Ahmed, I read your query regarding image reader
for NIST's ihead standard. You mentioned that NIST has
a sample database of such images for downloading,
could please do me a favour,
(i) forward me the link of NIST where sample data of
ihead image is stored, I can not find it.

We have a time critical smart client application running on Windows 2000/XP
systems.
Is there any reliable service that would help in syncing the local system
time to atomic clock or local time at the least in case the user changes the
system clock in purpose or inadvertently?
- Network synchronization solutions in the network is manual I believe?
- Web service based sync could work but will not if the user is off line.
Any other...

I have database apps that depend on accurate time
settings on the system clock. Fancy that, huh? Well,
am trying to sync w/ the gvt's nist time server. From
a CMD window in Win XP, I type the following:
C:\DB\TimNall>Gonna set time wrong - say to 8AM
C:\DB\TimNall>time
The current time is: 12:07:12.80
Enter the new time: 8:00:00

I would like to use the timestamp on files to manage the
currency of support files for my VB windows application.
In this case I would only put the timestamp of the file
in the management database and not the file itself.
To do this I will need to have a File class property for
Create time and date that will let me "set" the Create
time and date of the file to my own chooseing.
The VB file class does not appear to have the ability

I orginally posted this to microsoft.public.sqlserver.ce but had not

I have a CF.NET application (C#) with a SqlCE database. We had
originally planned to use SQL Authentication to replicate with the

our client asked us to use Windows Authentication instead.
For incremental changes, Windows authentication works fine. When

Hello everyone:
I am normally not an advocate of increasing the priority of a running
process or of a thread but it looks like I have to choice. I'm writing a
small app that plays a line-in signal via speakers using low level Digital
Audio API and as you can imagine it is quite time critical. The app works
fine when computer is idle but then even when I minimize a window (any
window), let alone do something more involving the play-back...

Hi all!
I have a question about thread synchronization and c++ streams
(iostreams, stringstreams, etc). When optimizing a program for a
multicore processor I found that stringstream was causing a LOT of
synchronization overhead. After a bit of digging I concluded that this
synchronization has to do with the access to a global locale inside
the stream.
The problem can be seen by running the small distilled benchmark code

Cognaxon has released "NIST (ANSI/NIST-ITL 1-2000) library" which
adds
the power of NIST (ANSI/NIST-ITL 1-2000) file format to your software
projects using only a few lines of code.
Additionally "NIST (ANSI/NIST-ITL 1-2000) library" has built-in
support
for decompressing fingerprint images from WSQ image format.
The advantage of NIST files is the ability to contain multiple images

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...

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....
Now, this would greatly impact the work of software developers. The idea...

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...
