An emulator for the HP 49g+/50g calculator series. This is an ARM-based
emulator (unlike emu48 / debug4x), so it is possible to run hpgcc
binaries within the emulator.
Skins for both variants of the calculator are included.
Known limitations:
- Cannot write to port 2. Libraries will eat up your RAM.
- HPGCC2/3 SD I/O is unstable.

XZX is a portable emulator of ZX Spectrum 48K/128K/+3 (8-bit home computers
made by Sir Clive Sinclair) for machines running UNIX and the X Window system.
XZX emulates either a Spectrum 48K, 128K or +3, Interface I with up to 8
microdrives, Multiface 128 (if you have the ROM image) and Kempston joystick.
XZX loads from .SNA, .Z80, .SLT, .DAT, .TAP, .TZX, .VOC, .MDR and .DSK files
and saves to .SNA, .Z80, .SLT, .TAP, .MDR, .DSK and .SCR files.
XZX will work with color (8,16,24,32bpp) and monochrome displays, where
contrasting colours are displayed with the darker colour in black and the
lighter colour in white, which works reasonably well. Halftoning is used if
the scaling factor is increased.

Expense is a very lightweight application to track your expenses,
much like you might expect to find on a PDA. It is built upon the
code found in Yen-ju Chen's excellent money.app tutorial.
I use Expense daily, but it still contains bugs.

The aim of the program is to make it as easy as possible for people to
do their own personal budgets and keep track of their finances.
These subroutines tell you whether a credit card number is
self-consistent -- whether the last digit of the number is a valid
checksum for the preceding digits.
The validate() subroutine returns 1 if the card number provided passes
the checksum test, and 0 otherwise.
The cardtype() subroutine returns a string containing the type of card:
"MasterCard", "VISA", and so on. My list is not complete; I welcome
additions.
The generate_last_digit() subroutine computes and returns the last digit
of the card given the preceding digits. With a 16-digit card, you
provide the first 15 digits; the subroutine returns the sixteenth.
NAME
Business::MaxMind::CreditCardFraudDetection - Access MaxMind minFraud
services
ABSTRACT
This module queries the MaxMind minFraud service and returns the
results. The service uses a free e-mail database, an IP address geog-
raphy database, a bank identification number, and proxy checks to
return a risk factor score representing the likelihood that the credit
card transaction is fraudulent.
Provides common bindings for Stripe payment system. Any API calls that do not
have bindings can be access through the generic api method.
Business::OnlinePayment is a generic interface for processing payments through
online credit card processors, online check acceptance houses, etc. (If you
like buzzwords, call it an "multiplatform ecommerce-enabling middleware
solution").
IMPORTANT: Business::OnlinePayment only defines the frontend interface to the
system, in order to use it you also need to have at least one backend
processing module installed, the processors supported are listed below along
with the types of transactions supported.
