Configuration of Microsoft ISA Proxy Server and Linux Squid Proxy Server
The paper concerns about basic Microsoft ISA server and Linux Squid Server configuration As a lot of technicians switch between ISA server and Squid server, I decided to write this paper to present some reference when configuring ISA and Squid. There a lot of issues that not covered, and you can go to the manual of ISA server and Squid server for detailed configuration of ISA and Squid. The paper is composed from two parts 1.Microsoft ISA server 2004 Configuration2.Linux Squid Server ConfigurationNote that, this work was done without proper simulation, because of the lack of resources, as testing firewall configuration requires many computers, with one of them should have many network cards. Also the ISA server is not used in the computer center now.I am Dr. Hidaia Mahmoud Mohamed Alassouli.

45 Elektronik-Projekte für den Raspberry Pi
Der Raspberry Pi stellt einen sehr preiswerten, aber doch vollwertigen Computer dar, an den auf einfache Weise verschiedenste Elektronik angeschlossen werden kann. Dieses Buch geht auf eine der Stärken des Raspberry Pi ein: die Kombination von Elektronik und Software.Nach einer kurzen Einführung zum Raspberry Pi wird auf die benötigte Software eingegangen. Im Anschluss wird das Linux-Betriebssystem kurz vorgestellt – gefolgt von einer Einführung in die Programmierung mit Bash, Python und JavaScript. Der Schwerpunkt liegt dabei auf Python. Die Erläuterungen sind in allen Fällen kurz und bündig und trotzdem so ausführlich, dass das Notwendigste besprochen wird, um die folgenden Projekte zu verstehen und individuell anzupassen.Dieses Buch beschreibt 45 spannende und interessante Projekte, wie zum Beispiel ein Wechselblinklicht, eine Motorregelung, Erzeugen und Verarbeiten analoger Signale, ein digitales Thermometer, ein Lichtmesser. Aber auch kompliziertere Projekte wie eine Motor-Geschwindigkeitsregelung, ein Webserver mit CGI (Common Gateway Interface) und Client-Server-Programme werden vorgestellt. Sie können dieses Buch als Projektbuch verwenden und die Projekte nachbauen, um sie dann in der Praxis einzusetzen. Durch die ausführliche Beschreibung mit Schaltplänen und Fotos gestaltet sich der Aufbau auf dem Steckbrett recht einfach.Sie können dieses Buch auch als Lehrbuch verwenden. Bei jedem Projekt wird erklärt, warum es auf diese Art und Weise ausgeführt ist. Sie lernen viel über den Raspberry Pi, Python und die verwendeten Bauteile, so dass Sie selbst die Projekte anpassen, nach eigenen Wünschen erweitern oder mehrere Projekte miteinander kombinieren können.Um Ihnen die Software-Installation zu erleichtern, hat der Autor das Betriebssystem und alle Programmbeispiele auf einer SD-Karte zusammengetragen.

Technical colleges and universities are moving away from legacy 8 and 16-bit microcontrollers and are introducing 32-bit embedded microcontrollers to their curriculums. Many IoT applications demand precision, high processing power, and low power consumption.Produced by IBM, Node-RED is an open-source visual editor for wiring the Internet of Things. Node-RED comes with a large number of nodes to handle a multitude of tasks. The required nodes are selected and joined together to perform a particular task. Node-RED is based on flow type programming where nodes are configured and joined together to form an application program. There are nodes for performing complex tasks, including web access, Twitter, E-mail, HTTP, Bluetooth, MQTT, controlling GPIO ports, etc. One particularly nice aspect of Node-RED is that the programmer does not need to learn how to write complex programs. For example, an email can be sent by simply joining nodes together and writing only a few lines of code.The aim of this book is to teach how Node-RED can be used in projects. The main hardware platform used with most of the projects in this book is Raspberry Pi 4. Chapters are included to show how Node-RED can be also be used with Arduino Uno, ESP32 DevKitC, and the ESP8266 NodeMCU microcontroller development boards.Prof. Dr. Dogan Ibrahim is a Fellow of the Institution of Electrical Engineers. He is the author of over 60 technical books, published by publishers including Wiley, Butterworth, and Newnes. He is the author of over 250 technical papers, published in journals, and presented in seminars and conferences.

Beginning Ring Programming
Gain a gentle introduction to the world of Ring programming with clarity as a first concern using a lot of practical examples. The first part lays the foundations of the language and its basic features (data types, control structures, functions, and classes). The unique way to rigorously structure Ring programs is also explained.Then, in the second part you’ll discover Ring inputs, outputs, and what is in between. You’ll use the basic constructs of computer logic (sequence, selection, and iteration) to build simple and complex logic flows. You’ll go over the common mistakes that lead to code complexity, by example, and cover several strategies to solve them (refactoring, code cleansing, and good variable naming). Then, you’ll see a visual illustration of how Ring deals with scopes at the local, object, and global levels.In part three, you’ll play with two artifacts vital to Ring programming: functions and objects. You’ll learn how they can be composed to solve a problem and how advanced programming paradigms, such as declarative and natural, are beautifully implemented on top of them. As part of the discussion, you’ll also work on game programming. You’ll learn how you design your game declaratively, in Ring code, just as if you were designing it in visual software.Finally, the author lays out how programming can be understood in a gamified context. You will be told the truth about how gaming can be a better metaphor to achieve mastery of Ring programming.This book is for those who are passionate about writing beautiful, expressive, and learnable code. It has been designed so you can enjoy a beginner-friendly set of knowledge about Ring, and benefit from a one-stop collection of lessons learned from real-world, customer-facing programming projects.WHAT YOU WILL LEARN* Get started with Ring and master its data types, I/O, functions, and classes* Carry out structural, object-oriented, functional, declarative, natural, and meta programming in Ring* Use the full power of Ring to refactor program code and develop clean program architectures* Quickly design professional-grade video games on top of the Ring game engineWHO THIS BOOK IS FORBeginners looking for a consistent and hackable programming environment with a strong flavor of learnability and expressiveness.Mansour Ayouni is one of the leading contributors to the new Ring programming language. He wrote his first BASIC computer statement, in the mid-80s, using only pen and paper, when he was 10 years old. It wasn’t in a California garage though nor under the lights of the prestigious Evil tour of Paris, but in the rural village of Regueb in the center of Tunisia (North Africa) where there was no electricity nor computers at all. Over the years, programming took him in an otherwise impossible international journey. From Tunisia, to Niger, to Canada, he contributed to the development of dozens of software products ranging from lawyer office management solutions to banking and nuclear waste management systems. During his career, he used to oversee programmers from three cultures and lead software teams in various companies such as Whitecape, Keyrus, and Webgenetics. Now, he is a member of the Ring core team and running Kalidia Consulting helping businesses make effective software.

Next, you'll learn about typeglobs for symbolic entries.Additionally, you'll see advanced subroutine handling, then packages and namespaces. Furthermore, you'll build advanced modules and install CPAN modules. Unlike Java and C++, modules have been around in Perl for a long time now. Along the way, you'll learn and use POD mark up language for Perl documentation.Moreover, you'll get a survey of the many advanced features and data structures of the current Perl programming language. You'll also get a survey of the new features of the latest Perl 5.x release. After reading and using this book, you'll have the tools, techniques, and source code to be an expert Perl programmer.WHAT YOU WILL LEARN* Carry out command-line parsing and extract scripts * Create references; return values from a reference; work with the ref Function and strict refs* Work with advanced Perl data types using arrays, hashes, and hash of hashes * Use Typeglobs for symbol table entries * Build modules and install CPAN modules* Write documentation for Perl using POD * Work with the newest features in Perl, including the smartmatch operator, yada yada, automated regex modifiers, the CORE namespace and moreWHO THIS BOOK IS FORThose with experience with Perl or who have read Rothwell's prior books, Beginning Perl Programming and Pro Perl Programming. At the impressionable age of 14, William "Bo" Rothwell crossed paths with a TRS-80 Micro Computer System (affectionately known as a “Trash 80”). Soon after the adults responsible for Bo made the mistake of leaving him alone with the TSR-80. He immediately dismantled it and held his first computer class, showing his friends what made this “computer thing” work. Since this experience, Bo’s passion for understanding how computers work and sharing this knowledge with others has resulting in a rewarding career in IT training. His experience includes Linux, Unix, DevOps tools, and programming languages such as Perl, Python, Tcl, and BASH.Chapter One Command Line Options1.1 Introducing Command Line Options1.2 Changing Input Record Separator1.3 Create a Loop Around Your Script1.4 Editing in Place1.5 Syntax Checking1.6 Pre-appending to @INC1.7 Including Modules1.8 Command Line Parsing1.9 Displaying Configuration Information1.10 Extracting Scripts from Messages1.11 Additional Resources1.12 Lab ExercisesChapter Two References2.1 What are References?2.2 Creating References2.3 Returning the Value from a Reference2.4 The ref Function2.5 Making Anonymous References2.6 References to Functions2.7 use strict ‘refs’2.8 Additional Resources2.9 Lab ExercisesChapter Three Advanced Data Types: Arrays3.1 Review: What You Should Already Know About Arrays3.2 What You Might Know About Arrays3.3 Arrays of Arrays3.4 Creating Arrays of Arrays3.5 Accessing Values in an Array of Arrays3.6 Adding a Sub Array (Row)3.7 Adding a column3.8 Printing an Array of Arrays3.9 Additional Resources3.10 Lab ExercisesChapter Four Advanced Data Types: Hashes4.1 Review: What You Should Already Know About Hashes4.2 What You Might Know About Hashes4.3 Hashes of Hashes4.4 Creating Hashes of Hashes4.5 Accessing Values in a Hash of Hashes4.6 Other Data Structures4.7 Additional Resources4.8 Lab ExercisesChapter Five Typeglobs5.1 Symbolic Tables5.2 Typeglobs5.3 Using typeglobs5.4 References vs. Typeglobs5.5 Avoiding Aliases to Entire Identifier5.6 Making constants5.7 Passing Filehandles into Functions5.8 Redefining a Function5.9 Temporarily Redefining a Function5.10 Additional Resources5.11 Lab ExercisesChapter Six Advanced Subroutine Handling6.1 Review: What You Should Already Know About Functions6.2 What You Might Know About Functions6.3 Making Persistent Function Variables6.4 Using the caller Function6.5 Passing Arguments by Reference6.6 Determining Functions Return Data6.7 Returning Multiple Values6.8 Exception Handling6.9 Constant Functions6.10 Prototypes6.11 Additional Resources6.12 Lab ExercisesChapter Seven Packages and Namespaces7.1 Scope7.2 Creating Namespaces with the package Command7.3 Fully Qualified Package Names7.4 Nested Packages7.5 use strict 'vars'7.6 Identifiers Not Affected by Packages7.7 Determine the Current Package7.8 Packages vs. my Variables7.9 Additional Resources7.10 Lab ExercisesChapter Eight Building Modules8.1 Introduction to Perl Modules8.2 Creating a Module8.3 BEGIN and END Blocks8.4 Symbol Tables in Modules8.5 Exporting Identifiers from Modules8.6 Private Identifiers8.7 Oking Symbols to Export from Modules8.8 Module Version Numbers8.9 use vs. require8.10 A Note About Library Files8.11 Additional Resources8.12 Lab ExercisesChapter Nine Installing CPAN Modules9.1 What is CPAN?9.2 Accessing CPAN9.3 CPAN Organization9.4 Installing a CPAN Module Manually9.5 Installing CPAN Modules Using the CPAN Module9.6 Using the Perl Package Manager to Install CPAN Modules9.7 Listing What Modules are Currently Installed9.8 Additional Resources9.9 Lab ExercisesChapter Ten POD10.1 Overview of POD10.2 POD Commands10.3 POD Text10.4 POD Verbatim10.5 POD Examples10.6 Common POD Problems10.7 POD Utilities10.8 Additional Resources10.9 Lab ExercisesChapter Eleven Advanced Features11.1 Perl development environments11.2 The power of the do statement11.3 autodie11.4 String variables as files11.5 File::Spec11.6 Proper use of soft references11.7 Install modules from CPAN without admin privileges11.8 Basic testing11.9 Advanced testing11.10 Using prove11.11 BenchmarkingChapter Twelve Advanced Data Structures12.1 Introduction to Benchmarking12.2 Use the Readonly module to create constants12.3 Make large numbers more readable12.4 Make use of Scalar::Util12.5 Make use of List::Util12.6 Make use of List::MoreUtils12.7 List formatting12.8 Understand slices12.9 Make use of Hash::Util12.10 Make use of Hash::MoreUtils12.11 Smart use of subscripts12.12 Understand the advantages and disadvantages of for, foreach, grep and map12.13 Know different sort techniques12.14 Avoid using memory to store large dataChapter Thirteen New Features12.1 Perl versions12.2 The latest/greatest?12.3 Changes by version12.4 The feature pragma12.5 Make use of the Smartmatch Operator12.6 The // operator12.7 The UNITCHECK block12.8 Yada yada12.9 The autodie pragma12.10 Using each, keys, values with arrays 12.11 New Regular Expression modifiers12.12 Non-destructive substation12.13 Automating Regular Expression modifiers12.14 New feature for given12.15 Change in use feature12.16 The CORE namespace12.17 Overriding Perl keywords
