30 game scripts you can write in PHP, Part 1: Creating 10 fundamental scripts Getting started As both a game master/storyteller and a developer, I frequently find myself writing little utilities and scripts to help me when running, planning, and playing games. Sometimes I need a quick idea. This article will explore 10 fundamental scripts that can be used in various types of games. We will blaze through these scripts pretty quickly. Back to top A basic die roller Many games and game systems need dice. In many cases, that would be more or less fine. Listing 1. function roll () { return mt_rand(1,6); } echo roll(); Then we can pass the type of die we want to roll as a parameter to the function. Listing 2. function roll ($sides) { return mt_rand(1,$sides); } echo roll(6); // roll a six-sided die echo roll(10); // roll a ten-sided die echo roll(20); // roll a twenty-sided die From here, we can go on to rolling multiple die at once, returning an array of results, or rolling multiple die of different kinds all at once, depending on our needs.

Help Desk Geek | Help Desk Tips for IT Pros Motion Mountain - The Free Physics Textbook for Download An Overview of Cryptography As an aside, the AES selection process managed by NIST was very public. A similar project, the New European Schemes for Signatures, Integrity and Encryption (NESSIE), was designed as an independent project meant to augment the work of NIST by putting out an open call for new cryptographic primitives. NESSIE ran from about 2000-2003. While several new algorithms were found during the NESSIE process, no new stream cipher survived cryptanalysis. As a result, the ECRYPT Stream Cipher Project (eSTREAM) was created, which has approved a number of new stream ciphers for both software and hardware implementation. CAST-128/256: CAST-128, described in Request for Comments (RFC) 2144, is a DES-like substitution-permutation crypto algorithm, employing a 128-bit key operating on a 64-bit block. A digression: Who invented PKC? 3.3. Let me reiterate that hashes are one-way encryption. A digression on hash collisions.
Electrical / Electronics Conversions Formulas & References - RF Cafe Throughout the years as an engineer, I have needed to research topics on engineering, physics, chemistry, mechanics, mathematics, etc. The Internet has made the job infinitely simpler, with the caveat that you have to be careful of your sources. Anyone can post anything on the Internet without peer review, and errors are rampant. The topics listed below are primarily ones that I have researched and generated custom pages for the content.
