Blender 2.49 Scripting: Impression using Different Mesh on Each Frame of Object

by Michel J. Anders | May 2010 | Open Source Web Graphics & Video

Having covered what script links and space handlers are in the previous article, we will take the discussion further on how Python can be used in Blender. Although softbody and cloth simulators that are available in Blender do an excellent job in many situations, sometimes you want to have more control over the way a mesh is deformed or simulate some specific behavior that is not quite covered by Blender's built-in simulators. This article shows how to calculate the deformation of a mesh that is touched, but not penetrated by another mesh. This is not meant to be physically accurate. The aim is to give believable results for solid things touching an easily deformable or gooey surface such as a finger taking a lick of butter or a wheel running through a soft shoulder.

In this article by Michel Anders, author of Blender 2.49 Scripting, you will learn:

  • How to implement a scheme to associate a different mesh with an object on each frame
  • How to augment the functionality of the 3D View

Blender 2.49 Scripting: Animating the Visibility of objects

by Michel J. Anders | May 2010 | Open Source Web Graphics & Video

There are many places where Python can be used in Blender. In this article by Michel Anders, author of Blender 2.49 Scripting, we will now look at scripts that may be used to act on certain events. These scripts come in two flavors—script links and space handlers. You will learn what script links and space handlers are and how they can be used to perform activities on each frame change in an animation. You also see how to associate additional information with an object, how to use script links to make an object appear or disappear by changing its layout or changing its transparency.

Compiling and Running Handbrake in Ubuntu

by Delan Azabani | May 2010 | Linux Servers Open Source Web Graphics & Video

Handbrake is considered the Swiss Army knife of video conversion tools. Running on the three major operating system platforms, Handbrake can open a huge variety of formats, including common ones that others can't handle (like the titles in the MPEG TS structure of a DVD). Handbrake outputs to a small selection of efficient formats, including H.264/MPEG-4 AVC, MPEG-4 ASP and Theora video. It has advanced features including chapter marking, subtitle inclusion and audio selection, plus filters for optimising video. On Linux, Handbrake can make use of the libdvdcss2 library to decrypt CSS-protected DVDs in-place during encoding, saving the need to use DVD Decrypter or another tool, usually through Wine. This article by Delan Azabani will guide you through the process for building Handbrake, installing it and converting video with it.

Setting up MySQL Replication for High Availability

by Alex Davies | May 2010 | Cookbooks MySQL Open Source Web Development

MySQL Replication is a feature of the MySQL server that allows you to replicate data from one MySQL database server (called the master) to one or more MySQL database servers (slaves). MySQL Replication has been supported in MySQL for a very long time and is an extremely flexible and powerful technology. Depending on the configuration, you can replicate all databases, selected databases, or even selected tables within a database.

In this article, by Alex Davies, author of High Availability MySQL Cookbook, we will cover:

  • Designing a replication setup
  • Configuring a replication master
  • Configuring a replication slave without synchronizing data
  • Configuring a replication slave and migrating data with a simple SQL dump
  • Using LVM to reduce downtime on master when bringing a slave online
  • Replication safety tricks

Installing and Managing Multi Master Replication Manager(MMM) for MySQL High Availability is covered seperately.

Installing and Managing Multi Master Replication Manager(MMM) for MySQL High Availability

by Alex Davies | May 2010 | Cookbooks MySQL Open Source Web Development

Multi Master Replication Manager for MySQL ("MMM") is a set of open source Perl scripts designed to automate the process of creating and automatically managing the "Active / Passive Master" high availability replication setup discussed earlier in the article on MySQL Replication design recipe, which uses two MySQL servers configured as masters with only one of the masters accepting write queries at any point in time. This provides redundancy without any significant performance cost.

In this article, by Alex Davies, author of High Availability MySQL Cookbook, we will cover:

  • Multi Master Replication Manager (MMM)
    • Initial installation
    • Installing the MySQL nodes
    • Installing the monitoring node
  • Managing and using Multi Master Replication Manager (MMM)
