Book Review: Animating with Blender by D. Roland Hess

Among the books I've read to get my head around the process of creating an animated film with Blender, this one is definitely the best. Nowadays you'll probably want to use Blender 2.5 or later, and this book is based on 2.49, but even with this problem, I'd still recommend it. The real win of this book is the way it deals with the synoptic view of the project: how to organize your project, how to break it down into manageable chunks, and even how to store it on disk. It's an excellent resource.

Book Review: Bounce, Tumble, and Splash! by Tony Mullen

Modeling every single aspect of a scene in a 3D application like Blender is hard when details are very fine (as with hair, bubbles, smoke, or a field of grass), and so there are a variety of automated techniques for pseudo-random modeling. It's also hard to animate every behavior accurately and realistically, especially of complex deforming surfaces. Fortunately, Blender can work out the physics -- applying gravity, collisions, and flexible movement for you. This book is a guide to this difficult subject.

Object and Camera Path Tracking in Blender - "Monkey See Monkey Do"

Blender has a useful set of constraint-based animation tools which make it fairly simple to animate motion of objects or of the camera along controlled paths. I expect to use this a lot, so I want to make sure I understand how it works. Here I'm going to work out a simple example using the "Suzanne" monkey meshes in Blender 2.49 to demonstrate simple path and tracking constraints with a mesh and with the camera. Because everything is better with monkeys.

Video editing with Kdenlive: Might be the sweet spot

So far, my favorite video editing app is Kdenlive. I found that it provided a relatively shallow learning curve and a familiar multi-track interface, but it also didn't make it hard to get to the kinds of controls I need for the precise control I want to have on vocational editing jobs.

Video editing with OpenShot: Capable, but lacks some polish

The OpenShot video editor was the easiest to get in Ubuntu Studio's "Oneric Ocelot" release, so we had a chance to try it out recently. It's pretty good -- much more capable than Kino. It provides similar capabilities to Blender's VSE, but without the burden of learning Blender. In fact, the learning curve is very gentle, because the interface is clean and simple.

Bach's Goldberg Variations commissioned for Public Domain Release

One of the responses to my earlier post about the MusOpen symphony recording project mentioned a project I had overlooked: the Open Goldberg project has created new public domain scores for the Bach's "Goldberg Variations" using the MuseScore free software musical notation software and is commissioning a studio recording of piano soloist Kimiko Ishizaka performing the pieces, also for public domain release (with

A company, zero to operational and profitable, in 5 days with free software

Everything started with a simple question my wife asked me: you are so good at teaching, why don't you do it? Given that I will only ever work in my own term, I would have to organize everything on my own: incorporation, web site, stationery, advertising, the lot. Chiara's question was natural: well, you can do all that basically for free with Free Software, right?

Right. So, the adventure begins: the bet is that I will have a company, zero to profitable (that means with customers, bookings, etc.) in 5 days.

Answering a tricky question with the KStars desktop planetarium package

In an earlier phase of my life, I worked as a professional astronomer, and I've loved space and astronomy since before I could pronounce the words. So naturally, I've gotten a lot of personal pleasure from the free software astronomy tools that are included in my Debian GNU/Linux system. But ironically, I haven't written about them much. Recently, though, I was asked a question which I used KStars to answer, so this is a good chance to talk about how to use it.

Libre.fm: A music sharing site just for free-culture works

You've probably heard of "Last FM", a music playlist site that allows users to track their favorite bands and listen to music streamed over their mobile devices. But you may not have heard of Libre FM, a recent free software project and free culture web application intended to serve this purpose exclusively for free-licensed musical works.

Exploitation? Entrepreneurship, Capitalism, and Making Money on Free Software

Recently, I was directed toward an excellent analysis of commons-based peer production as a phenomenon which separates "entrepreneurs" (who want to get things done and create value in the world) from "capitalists" (who want to get a return on an investment of property without contributing any labor). An observer -- clearly outside of the community of free software developers -- expressed dismay at the example of Mozilla Foundation, which makes money from the open source Mozilla project, but does not pay for most voluntarily contributed code improvements to the Mozilla software. Is he right? Is this exploitation of those contributors?

Why You Should Join Diaspora Now, Like Your Freedom Depends On It

I never really "trusted" Facebook or Google+. That is to say, I never expected them to respect my privacy or keep my secrets. I'm not too secretive online anyway, and what I do have to hide, I just don't post. But it is very clear that there is a great deal of corruption inherent in a business model which is based on concentrating the personal data from millions of users and selling that data to advertisers. At the very least, there must be a free alternative. But for that alternative to be viable, we need to use it. Identica has been around for some time now (and I use it -- I'm "digitante"), and Diaspora is (after a long hard start) finally getting some wind under its wings. I've used it, and it's Good Enough. In fact, you'll find it's pretty similar to what Facebook or Google+ offers, although there are still some rough spots.

Hobby Robotics with Free Software: Part 2 - Arduino

As I mentioned in my previous column, my son and I want to explore robotics as a hobby and a learning experience. We don't have an unlimited budget, so I wanted to do some estimating of what it would cost to do it using different technology standards. In the first part, I explored Lego Mindstorms, but the open-hardware (and free software) Arduino system has been getting better and better. So I want to consider that possibility in this column and make a comparison to see which is a better option for us.

Three Real-Time Animation Methods: Machinima, Digital Puppetry, and Motion Capture

In planning the production of the Lunatics series, the most obvious challenge is simply how to do that much animation on such a low budget. Conventional "key frame" animation (which is what Blender excels at and is what familiar 3D movie studios like Pixar use to create their blockbuster films) is beautiful, but it's also painstakingly slow work. Animators live for this stuff, but for me, it's a mountain that just might crush my project. Fortunately, it's not the only way. There are methods for making animation more like acting -- creating a performance in real-time and capturing it in a simulated world. These can be broken down into three basic methods (although they can be used together, creating many overlapping variations): "machinima", "digital puppetry", and "motion capture". Each is a "bleeding edge" area for free software development, but tools do exist.

Free Software needs Free Speech!

You might think that a good program is all about good programming. But for a number of applications, the barrier to success isn't programming at all. Some of the most interesting projects nowadays -- speech recognition, for example -- rely on machine-learning from databases of information. It's not enough to write free software for these applications, we have to also provide that software with the right data. Contributing to these projects is needed from a much larger group of people, but it also can be very easy to do.

The OpenPC project: Ready-made GNU/Linux Machines

The Open Desktop communities Open-PC project is now offering three different models of open computers with turn-key GNU/Linux and KDE installations based on OpenSUSE (or Ubuntu). These systems could provide real competition with pre-installed Windows or Mac computers, overcoming some of the most frequently-cited problems with GNU/Linux on the desktop. The systems are now available from vendors in Europe and the USA.

Free Software: the road to a Universal bundle, a powerful app store, and world domination

Apple is doing it again: they are releasing an app store for OS X on the 6th of January. Just like the iPhone app store, and the Android app store, this is going to be a hit: the OS X ecosystem will get a giant boost from it, and we are left -- once again -- with a lot to learn. Before you mention that GNU/Linux doesn't need an app store because it's free software, and before you even say that GNU/Linux already has an app store through one of the many software managers (Synaptics, Ubuntu Software Center, apt-get), please read this article.

Sintel DVDs have shipped with film, commentaries, and Blender tutorials

My DVD set for the Blender Foundation's latest open movie, "Sintel," arrived this month. Considering the size, expense, and duration of the production, it's a truly amazing short film. There's much more emotional weight here than in "Elephants Dream" or "Big Buck Bunny." More of interest here, though, is the huge amount of supplementary material included in the set. This is more than just the sources for the movie. There's also a lot of tutorial information for Blender users and of course, an array of personal commentaries on the production process.

The bad guys are worried - did we win?

Recently two pieces of first class anti-free software diatribe hit the headlines. The first is Microsoft's "please don't use OpenOffice.org" video and the second is Steve Jobs' anti-Android rant. Both are pretty shallow attempts at deflection and have been rightly called out as actually endorsing the subject of the attack as a valid opponent. In both cases it does seem to say that Microsoft and Jobs are concerned enough about OpenOffice.org and Android respectively that they need to tell the rest of us how bad they are.

Learning with TuxMath

Rote learning of "math facts" is one of the really dull aspects of grade-school mathematics. But if you can't recall them quickly, it can really hold you back even in higher mathematical disciplines, because it just slows you down. My son's been struggling with this for some time now, with traditional solutions like flash cards just not working very well. With "Tux of Math Command", otherwise known as "TuxMath", though, he's making considerable progress at overcoming his "wall" with math. Homework times are getting shorter because his recall speed is getting much better with just one or two games a day -- an easy goal to reach because the games are actually fun (Seriously. I play it myself now and then).

7 Things We Don't Have to Invent for Animation Production (Thanks to Free Software and Previous Free Culture Productions)

Counting your blessings is good for the soul -- not to mention for convincing yourself and any investors that your project will succeed. Free culture is highly conservative, because it's possible to simply reuse ideas (and sometimes actual artifacts) with little to no cost. Here's seven things I'm really glad I don't have to worry about in designing the production model for our free culture animated series Lunatics.

Anybody up to writing good directory software?

Since the very beginning, directories (of any kind) have had a very central role in the internet. (I have recently grown fond of Free Web Directory. Even Slashdot can be considered a directory: a collection of great news and invaluable user-generated comments. As far as software is concerned, doing a quick search on Google about software directories will return the free (as in freedom) software directories like Savannah, SourceForge, Freshmeat and so on, followed by shareware and freeware sites such as FileBuzz, PCWin Download Center and All Freeware (great if you're looking for shareware and freeware, but definitely less comprehensive than their free-as-in-freedom counterparts).

Is better education the key to finding better software?

I read David Jonathon's article Anybody Up To Writing Good Directory Software? the other day, which got me thinking about software directories in general. As David mentioned, many of the software directories one finds when doing a quick google search are free as in beer, not as in freedom. But what interests me is the software directories that already exist, providing a combination of both free as in beer software, and open source software. Sites such as Freeware Downloads and Shareware Download don't advertise themselves as providing free as in liberty software, but each of them have a good selection of open source software available... if you know where to look.

Creating a user-centric site in Drupal

A little while ago, while talking in the #drupal mailing list, I showed my latest creation to one of the core developers there. His reaction was "Wow, I am always surprised what people use Drupal for". His surprise is somehow justified: I did create a site for a bunch of entertainers in Perth, a company set to use Drupal to take over the world with Entertainers.Biz.

Update: since writing this article, I have updated the system so that the whole booking process happens online. I will update the article accordingly!

So, why, why do people and companies develop free software?

More and more people are discovering free software. Many people only do so after weeks, or even months, of using it. I wonder, for example, how many Firefox users actually know how free Firefox really is—many of them realise that you can get it for free, but find it hard to believe that anybody can modify it and even redistribute it legally.

When the discovery is made, the first instinct is to ask: why do they do it? Programming is hard work. Even though most (if not all) programmers are driven by their higher-than-normal IQs and their amazing passion for solving problems, it’s still hard to understand why so many of them would donate so much of their time to creating something that they can’t really show off to anybody but their colleagues or geek friends.

Sure, anybody can buy laptops, and just program. No need to get a full-on lab or spend thousands of dollars in equipment. But... is that the full story?
