Converting Maya FBX Files

Maya is used for a lot of 3D modeling. Modelers frequently save their completed work in a FBX file. FBX is a proprietary format designed by Autodesk (check this). In addition to the model, it contains the textures, rigging, and animation. It is a very convieient format, if you have an appropriate library of other tool to unpack it. Blender is an open-source modeling program. There is an FBX importer in Blender that handles many of the features and variations of the FBX format.

Net Neutrality

Net Neutrality is showing up as one of the top stories shortly after the 2014 elections. It is not an easy topic to understand, especially with all of the claims and counter-claims flying around the Internet. Many of the statements are made by people who have no idea what is involved but are taking their position purely for political or personal financial reasosns. This post is an attempt to explain in relatively simple terms what is involved in Net Neutrality by using familiar analogies.

3D Google Cardboard

In a previous post I showed how a scene could be displayed in a browser and viewed stereoscopicly with Google Cardboard. This post describes a more efficient means of creating the display. In both cases, the browser screen is split in half with slightly different viewpoints so the eyes/brain combination views the result with depth.

This is a short follow-on to the Passwords and Hacking series.

The Internet worm "Morto A" continues to infect computers. It uses Microsoft's Remote Desktop to spread. It attempts to gain access to your computer using Remote Desktop's protocol. It will succeed if your password is one of 37 simple passwords listed below.

Internet Explorer has Major Bug

Microsoft has confirmed that Internet Explorer (all versions) has a bug that allows the browser to run software as you on your computer. Making it happen is rather technical, but it can happen when you go to a "specially crafted"1 web site that downloads the code into the browser than causes the browser to execute the code as if it were part of the browser's regular code. The attacks "in the wild"2 use Flash on IE V9, 10, and 11.
