The Search pages in the Database or Table view are intended for single-table lookups. This article by Marc Delisle, covers the multi-table Query by example (QBE) feature available in the Database view.
Many phpMyAdmin users work in the Table view, table-by-table, and thus tend to overlook the multi-table query generator, which is a wonderful feature for fine-tuning queries. The query generator is useful not only in multi-table situations but also for a single table. It enables us to specify multiple criteria for a column, a feature that the Search page in the Table view does not possess.Read The Multi-Table Query Generator using phpMyAdmin and MySQL in full
An HTTP server is primarily a piece of software that will deliver web pages to clients when requested. These web pages can be anything from a simple HTML file on disk to a multicomponent framework delivering user-specific content, dynamically updated through AJAX or WebSocket. NGINX is modular, and is designed to handle any kind of HTTP serving necessary.
In this article by Dimitri Aivaloitis, author of Mastering NGINX , we will investigate the various modules that work together to make NGINX such a scalable HTTP server. The following topics are included in this article:
The HTTP core module
Using limits to prevent abuse
Streaming media files
Using NGINX with PHP-FPM
Wiring NGINX and uWSGI together

In this article, by Andrey Koleshko, author of the book Rake Task Management Essentials, we will cover the installation of Rake, the definition of basic terms such as rake task and Rakefile, and how to use them for easy programming issues. The introduction will be given using straightforward examples to explain the terms as clearly as possible. You will see that Rake is a tool that is written in the Ruby programming language, and that's why any Ruby code can be written in a Rake application. Also, you have the choice of using any available Ruby library in a Rake project. This feature makes Rake the winner compared to many other build tools, which use their own limited languages. The article will serve as a base for introducing Rake's Domain Specific Language (DSL) and project file structuring.
In this article, we will cover the following topics:
- Installing Rake
- Introducing rake tasks
- The command-line arguments
- Using global Rakefiles to run tasks anywhere
- Defining custom rake tasks
- The structure of a Rake project
- The code conventions of Rake
This article written by Luca Zamboni, the author of Getting Started with Simulink describes how solvers are used by Simulink to run the simulation. It explains how every solver perform the simulation by advancing one time step and computing the new outputs starting from the previous state(s) of the system until the end of the simulation time. The initial system state must be fully defined.
The appropriate solver for a model can be chosen by defining these characteristics:
- Time step size, which can be fixed or variable
- Presence of continuous states in the system
- Stiffness of the system
In this article, by Manuel Xavier, the author of TIBCO Spotfire for Developers, we will introduce the Spotfire Platform products, defining their independent roles in the platform's architecture.

The Trivadis Integration Architecture Blueprint specifies the building blocks needed for the effective implementation of integration solutions. It ensures consistent quality in the implementation of integration strategies as a result of a simple, tried-and-tested structure, and the use of familiar integration patterns (Hohpe, Wolf 2004).
In this article by Guido Schmutz, co-author of Service-Oriented Architecture: An Integration Blueprint, we will cover:
- Standards, components, and patterns used
- Structuring the integration blueprint
Having understood the structure of the blueprint covered in the previous article on The Trivadis Integration Architecture Blueprint, this article will use individual scenarios to illustrate how the business pattern can be implemented using the Integration Architecture Blueprint.
This article by Guido Schmutz, co-author of Service-Oriented Architecture: An Integration Blueprint, will:
- Explain service-oriented integration scenarios
- Explain how an existing integration solution can be modernized using SOA, and describe a scenario that has already been implemented in practice
In this article by Geoff Sholler, author of the book "Build a Game with UDK", we will explain the sound component of the Unreal Engine. The Unreal Engine is used in many games out on the market. It's also used in other industries for things such as simulation. Regardless of the use, any product using the Unreal Engine will also use the Unreal Development Kit and the tools within it. This article will cover most of the tools included in the Unreal Development Kit.Read The Unreal Engine in full
