Your first FuelPHP application in 7 easy steps

In this article by Sébastien Drouyer , author of the book FuelPHP Application Development Blueprints we will see that FuelPHP is an open source PHP framework using the latest technologies. Its large community regularly creates and improves packages and extensions, and the framework’s core is constantly evolving. As a result, FuelPHP is a very complete solution for developing web applications.

Python functions – Avoid repeating code

In this article by Silas Toms , author of the book ArcPy and ArcGIS – Geospatial Analysis with Python we will see how programming languages share a concept that has aided programmers for decades: functions. The idea of a function, loosely speaking, is to create blocks of code that will perform an action on a piece of data, transforming it as required by the programmer and returning the transformed data back to the main body of code. Functions are used because they solve many different needs within programming. Functions reduce the need to write repetitive code, which in turn reduces the time needed to create a script. They can be used to create ranges of numbers (the range() function), or to determine the maximum value of a list (the max function), or to create a SQL statement to select a set of rows from a feature class. They can even be copied and used in another script or included as part of a module that can be imported into scripts. Function reuse has the added bonus of making programming more useful and less of a chore. When a scripter starts writing functions, it is a major step towards making programming part of a GIS workflow.

Deployment Scenarios

In this article by Andrea Gazzarini , author of the book Apache Solr Essentials , contains information on the various ways in which you can deploy Solr, including key features and pros and cons for each scenario. Solr has a wide range of deployment alternatives, from monolithic to distributed indexes and standalone to clustered instances. We will organize this article by deployment scenarios, with a growing level of complexity. This article will cover the following topics: Sharding Replication: master, slave, and repeaters

iOS Security Overview

In this article by Allister Banks and Charles S. Edge , the authors of the book,  Learning iOS Security , we will go through an overview of the basic security measures followed in an iOS. Out of the box, iOS is one of the most secure operating systems available. There are a number of factors that contribute to the elevated security level. These include the fact that users cannot access the underlying operating system. Apps also have data in a silo (sandbox), so instead of accessing the system's internals they can access the silo. App developers choose whether to store settings such as passwords in the app or on iCloud Keychain, which is a secure location for such data on a device. Finally, Apple has a number of controls in place on devices to help protect users while providing an elegant user experience. However, devices can be made even more secure than they are now. In this article, we're going to get some basic security tasks under our belt in order to get some basic best practices of security. Where we feel more explanation is needed about what we did on devices, we'll explore a part of the technology itself in this article. This article will cover the following topics: Pairing Backing up your device Initial security checklist Safari and built-in app protection Predictive search and spotlight

Our App and Tool Stack

 In this article by Zachariah Moreno , author of the book AngularJS Deployment Essentials , you will learn how to do the following: Minimize efforts and maximize results using a tool stack optimized for AngularJS development Access the krakn app via GitHub Scaffold an Angular app with Yeoman, Grunt, and Bower Set up a local Node.js development server Read through krakn's source code Before NASA or Space X launches a vessel into the cosmos, there is a tremendous amount of planning and preparation involved. The guiding principle when planning for any successful mission is similar to minimizing efforts and resources while retaining maximum return on the mission. Our principles for development and deployment are no exception to this axiom, and you will gain a firmer working knowledge of how to do so in this article.

Native MS Security Tools and Configuration

This article, written by Santhosh Sivarajan , the author of Getting Started with Windows Server Security , will introduce another powerful Microsoft tool called Microsoft Security Compliance Manager ( SCM ). As its name suggests, it is a platform for managing and maintaining your security and compliance polices. At this point, we have established baseline security based on your business requirement, using Microsoft SCW. These polices can be a pure reflection of your business requirements. However, in an enterprise world, you have to consider compliance, regulations, other industry standards, and best practices to maximize the effectiveness of the security policy. That's where Microsoft SCM can provide more business value. We will talk more about the included SCM baselines later in the article. The goal of the article is to walk you through the configuration and administration process of Microsoft SCM and explain how it can be used in an enterprise environment to support your security needs. Then we will talk about a method to maintain the desired state of the server using a Microsoft tool called Attack Surface Analyzer ( ASA ). At the end of the article, you will see an option to add more security restrictions using another Microsoft tool called AppLocker .

Getting Started with PostgreSQL

In this article by Ibrar Ahmed , Asif Fayyaz , and Amjad Shahzad , authors of the book PostgreSQL Developer's Guide , we will come across the basic features and functions of PostgreSQL, such as writing queries using psql , data definition in tables, and data manipulation from tables.

PostgreSQL as an Extensible RDBMS

This article by Usama Dar , the author of the book PostgreSQL Server Programming - Second Edition , explains the process of creating a new operator, overloading it, optimizing it, creating index access methods, and much more. PostgreSQL is an extensible database. I hope you've learned this much by now. It is extensible by virtue of the design that it has. As discussed before, PostgreSQL uses a catalog-driven design. In fact, PostgreSQL is more catalog-driven than most of the traditional relational databases. The key benefit here is that the catalogs can be changed or added to, in order to modify or extend the database functionality. PostgreSQL also supports dynamic loading, that is, a user-written code can be provided as a shared library, and PostgreSQL will load it as required.

Creating a Brick Breaking Game

Have you ever thought about procedurally generated levels? Have you thought about how this could be done, how their logic works, and how their resources are managed? With our example bricks game, you will get to the core point of generating colors procedurally for each block, every time the level gets loaded. Physics has always been a huge and massively important topic in the process of developing a game. However, a brick breaking game can be made in many ways and using the many techniques that the engine can provide, but I choose to make it a physics-based game to cover the usage of the new, unique, and amazing component that Epic has recently added to its engine. The Projectile component is a physics-based component for which you can tweak many attributes to get a huge variation of behaviors that you can use with any game genre. By the end of this article by Muhammad A.Moniem , the author of Learning Unreal Engine iOS Game Development , you will be able to: Build your first multicomponent blueprints Understand more about the game modes Script a touch input Understand the Projectile component in depth Build a simple emissive material Use the dynamic material instances Start using the construction scripts Detect collisions Start adding sound effects to the game Restart a level Have a fully functional gameplay

Introducing Splunk

In this article by Betsy Page Sigman , author of the book Splunk Essentials , Splunk , whose "name was inspired by the process of exploring caves, or splunking, helps analysts, operators, programmers, and many others explore data from their organizations by obtaining, analyzing, and reporting on it. This multinational company, cofounded by Michael Baum, Rob Das, and Erik Swan, has a core product called " Splunk Enterprise . This manages searches, inserts, deletes, and filters, and analyzes big data that is generated by machines, as well as other types of data. "They also have a free version that has most of the capabilities of Splunk Enterprise and is an excellent learning tool.

Going beyond Zabbix agents

In this article by Andrea Dalle Vacche and Stefano Kewan Lee , author of Zabbix Network Monitoring Essentials , we will learn the different possibilities Zabbix offers to the enterprising network administrator. There are certainly many advantages in using Zabbix's own agents and protocol when it comes to monitoring Windows and Unix operating systems or the applications that run on them. However, when it comes to network monitoring, the vast majority of monitored objects are network appliances of various kinds, where it's often impossible to install and run a dedicated agent of any type. This by no means implies that you'll be unable to fully leverage Zabbix's power to monitor your network. Whether it's a simple ICMP echo request, an SNMP query, an SNMP trap, netflow logging, or a custom script, there are many possibilities to extract meaningful data from your network. This section will show you how to set up these different methods of gathering data, and give you a few examples on how to use them.

Basics of Programming in Julia

 In this article by Ivo Balbaert , author of the book Getting Started with Julia Programming , we will explore how Julia interacts with the outside world, reading from standard input and writing to standard output, files, networks, and databases. Julia provides asynchronous networking I/O using the libuv library. We will see how to handle data in Julia. We will also discover the parallel processing model of Julia. In this article, the following topics are covered: Working with files (including the CSV files) Using DataFrames
