Description: Decoding the signal from magnetic stripe card or ticket using just a simple magnetic head connected to a microphone jack. Recording an audio WAVE file, and then this information can be decoded by the 2 programs included.
First program dab.c decodes the audio signal into bits - 0s and 1s. The second program dmsb.c decodes bits into readable ascii code which can be read by a human. After this the decode process is complete.
The best thing of this software is that you can record the information from a magnetic stripe card, on your mp3 player and decode information later on. Or you can do it in real time when both programs are run with pipe command in Linux.
The source code can be modified and compiled for Windows. The license is GPL license - free to use. This was my graduation project in the Technical University for master degree in Informatics.

Description: The subject of this programming assignment is using Linux/UNIX system calls dealing
with processes and pipes.-The subject of this programming assignment is using Linux/UNIX system calls dealing
with processes and pipes. You are to write a C program that implements a simple client-
server system, where the server does centralized logging of messages from multiple clients.
The program is to create a set of subprocesses (children) using fork. The parent will function
as the logging server, and the children will function as clients, which send messages to the
server to be logged in a single log file. The client processes will use a pipe to send simple
messages to the server. Each will send a certain number of messages, at random intervals,
and then terminate. The server process will read all of the messages as sent, write them to
the log file, and eventually terminate after all the clients have terminated. Platform: |

Description: 在Linux环境下用C语言编程，编程的主要内容是：命名管道的实验。包括：研究mkfifo命令，在当前目录下创建一个myfifo的命名管道
用mkfifo（）函数实现相同的功能
编写一个服务器程序server.c，实现从管道myfifo中读取内容，并在终端中显示出来。打开一个命令行终端，运行server，然后打开另一个命令行终端，使用“cp 文件1 myfifo”命令把文件1的内容输出到myfifo，测试server.c的功能
编写客户机程序，实现把指定文件输出到myfifo的功能，从而实现和服务器程序的通信。测试该程序的功能。
-With the main content of the C programming language, programming in the Linux environment: Named Pipes experiments. Including: study mkfifo command to create a myfifo named pipe with mkfifo () function in the current directory to achieve the same functionality to write a server program server.c content achieve from the pipeline myfifo, read, and displayed in the terminal. Open a command line terminal, run the server, and then open another command line terminal the to " cp files 1 myfifo" command to output the contents of file 1 to myfifo, written test the functionality of the server.c client program to specify file output to functionality of myfifo, in order to achieve communication and server programs.

Description: 在 Linux 中 FIFO 是一种进程之间的管道通信机制。Linux 支持完整的 FIFO通信 机制。 本实验内容，通过使用文件操作，仿真 FIFO（先进先出）结构以及生产者-消费者运行模型。
本实验中需要打开两个虚拟终端，分别运行生产者程序（producer）和消费者程序（customer）。此时两个进程同时对同一个文件进行读写操作。因为这个文件是临界资源，所以可以使用文件锁机制来保证两个进程对文件的访问都是原子操作。
先启动生产者进程，它负责创建仿真 FIFO 结构的文件（其实是一个普通文件）并投入生产，就是按照给定的时间间隔，向 FIFO 文件写入自动生成的字符（在程序中用宏定义选择使用数字还是使用英文字符），生产周期以及要生产的资源数通过参数传递给进程（默认生产周期为 1s，要生产的资源数为 10 个字符）。
后启动的消费者进程按照给定的数目进行消费，首先从文件中读取相应数目的字符并在屏幕上显示，然后从文件中删除刚才消费过的数据。为了仿真 FIFO 结构，此时需要使用两次复制来实现文件内容的偏移。每次消费的资源数通过参数传递给进程，默认值为10 个字符。 -Linux is in FIFO pipe communication mechanism between processes. Linux supports a full FIFO communication mechanism. The experiment content, through the use of file operations, simulation FIFO (First In First Out) structure as well as producer- consumer model is run.
In this study we need to open two virtual terminals, each running program producers (producer) and consumer programs (customer). At this point two processes simultaneously on the same file for read and write operations. Because this document is the critical resource, so you can use the file locking mechanism to ensure access to the file two processes are atomic.
Producers first start process, it is responsible for creating the simulation FIFO file structure (actually a common file) and put into production, is in accordance with a given time interval, automatically generated characters written into the FIFO file (using macros define the selection the use of digital still use English characters), the production cycle and t Platform: |
