Custom PHP script to monitor the availability of server resources

This article describes a simple custom script that uses this Ping utility to monitor the availability of a list of IT resources (that support ICMP packets) by polling their IP addresses at a regular frequency. Their ping statuses are captured as events and are notified as email, SMS, and slack messages to the system administrators during ping failures.

An introduction to neural networks

Neural nets may be the future of computing. A good way to understand them is with a puzzle that neural nets can be used to solve. Suppose that you are given 500 characters of code that you know to be C, C++, Java, or Python. Now, construct a program that identifies the code's language. One solution is to construct a neural net that learns to identify these languages. This article discusses the basic features of neural nets and approaches to constructing them so you can apply them in your own coding.

Mastering recursive programming

Recursion is a tool not often used by imperative language developers because it is thought to be slow and to waste space. But as you'll see, there are several techniques that can be used to minimize or eliminate these problems. This article introduces the concept of recursion and tackles recursive programming patterns, examining how they can be used to write provably correct programs. Examples are in Scheme and C.
