Upgrading OpenCart

by Murat Yilmaz | August 2010 | Beginner's Guides Open Source

It is wise to update our OpenCart environment to the latest version regularly. It protects our system against security vulnerabilities and allows us to use new features. It is also possible that the new OpenCart version will have several bug fixes.

Moreover, new versions can have new bugs. Because of this, it is a common practice to wait while a version with major changes matures and gets rid of serious bugs with minor release fixes.

In this article by Murat Yilmaz, author of OpenCart 1.4 Beginner's Guide, we shall learn about:

  • Making a backup of current OpenCart system
  • Downloading the latest OpenCart version
  • Uploading the new files to a server
  • Running the upgrade script
  • Checking whether everything works as expected or not
  • Restoring the OpenCart system if an upgrade fails or has serious problems

Upgrading from Samba Server Version 3

by Marcelo Leal | April 2014 | Networking & Telephony Open Source

In this article by Marcelo Leal, author of Implementing Samba 4, the reader will learn some of the biggest differences between the Samba software Versions 3 and 4, and based on that, will understand the impact and the relevant considerations before planning a successful upgrade. The main aspects of such differences will be focused on the different working models and the new features and benefits that the upgrade can leverage.

We will learn about a step-by-step procedure to execute the upgrade and all the commands and scripts needed to go from Samba 3 to Samba 4's fully functional Domain Controller network services.

We will describe a guideline that can be well suited and requires just a few changes for small and medium installations, but bigger and more complex environments will need adjustments and customizations. The variety of configurations in production of the Samba Server Version 3 use cases are huge, and we will not be able to handle all the variations that our readers have implemented in their respective environments, but all the procedures and use case examples presented here should work as a rich base.

Updating Software in Koha

by Amit Gupta Savitra Sirohi | November 2010 | Open Source

The Koha software is always changing, almost every day. These changes contain bug fixes, minor revisions to existing features, and entirely new features. You should keep the software updated to benefit from these changes.

Even if the new versions do not contain changes of interest to you, it is good practice to keep the software updated. If your version falls too far behind the current version, the update process to the latest version is likely to be very difficult.

In this article, by Amit Gupta & Savitra Sirohi, authors of Koha 3 Library Management System, we will learn how to download and install software updates. We cover the article in two steps—an orientation followed by a demonstration of the process.

UNIX Monitoring Tool for PostgreSQL

by Gregory Smith | October 2010 | Open Source

Performance of your database server is directly tied to how well the underlying operating system is working, and there the performance is driven by the hardware you're using. To fit all of these pieces together—hardware performance, operating system performance, and database performance—you need a good monitoring system.

The simple performance tools on a UNIX-derived system are straightforward to use, and it's easy to show examples of good and bad behavior, the best way to teach how those tools are useful for monitoring. In this article by Gregory Smith, author of PostgreSQL 9.0 High Performance, we will cover iostat; Unix's monitoring tool.

Unity Game Development: Interactions (Part 2)

by Will Goldstone | October 2009 |

In the previous part of the article by Will Goldstone, we saw how to add an outpost model to our project and also learned how to position, scale, assign colliders to objects as well as tag objects. In this part, we will look at the two differing approaches for triggering the animation giving you an overview of the two techniques that will both become useful in many other game development situations. In the first approach, we'll use collision detection—a crucial concept to get to grips with as you begin to work on games in Unity. In the second approach, we'll implement a simple ray cast forward from the player.

Unity 3D Game Development: Don't Be a Clock Blocker

by Ryan Henson Creighton | September 2010 | Beginner's Guides Web Graphics & Video

One cheap, effective way of amping up the game experience is to add a clock. Games have used clocks to make us nervous for time immemorial, and it's hard to find a video game in existence that doesn't include some sort of time pressure—from the increasing speed of falling Tetris pieces, to the countdown clock in every Super Mario Bros. level, to the egg timers packaged with many popular board games like Boggle, Taboo, and Scattergories.

This article by Ryan Henson Creighton, author of Unity 3D Game Development by Example Beginner's Guide, shows you how to build three different game clocks: a number-based clock, a depleting bar clock, and a cool pie wedge clock, all of which use the same underlying code. You can then reuse the code in a game of your own.

Unity 3: Building a Rocket Launcher

by Jate Wittayabundit | September 2011 | Web Graphics & Video

Only Unity fits the bill of being a game engine that allows you to create a full 3D game for free, and with phenomenal community support.

In this article by Jate Wittayabundit, author of Unity 3 Game Development Hotshot, we will learn how to create a rocket launcher. Here, we will first use the FPS camera and controller from the Unity built-in FPS package, but we will tweak our camera view to see from the character's shoulder as in Resident Evil 4 or 5. Then, we will adapt the built-in FPS controller script to be able to play the animation of the character, and make the controller similar to the Resident Evil style controller. Next, we will create a rocket prefab and the rocket launcher script to fire our rocket, which will also include the use of the built-in fire explosion particle and custom smoke particle effect from the launcher when we fire.

Unity 3.x Scripting-Character Controller versus Rigidbody

by Devon Kraczla Volodymyr Gerasimov | June 2012 | Open Source

Character controller is extremely important part of any game. Essentially, it allows us to interact with it, control our alter-ego, shoot, explore, and do all kinds of crazy stuff. Most common character controller is humanoid, in general it needs to know how to walk, run, jump, attack, it needs to camera rig that will be accompanying it throughout play. All these actions need to be supported on a programming level and we will look into a way that it can be done in Unity. This article by Volodymyr Gerasimov and Devon Kraczla, the authors of the Unity 3.x Scripting, will help you to:

  • Learn Character Controller versus Rigidbody – pros and cons
  • Teach player-controlled character walk, run, jump, and shoot
  • Program camera controls and switching between different camera types with a press of a single button
  • Learn script animations to follow character's actions
