One of the most irritating myths promulgated by the entertainment industry is the idea that copyright is an ethical imperative because it's bad to "steal other people's ideas". This is frequently combined with an illustrative story of plagiarism -- in other words, a situation in which someone fraudulently claims credit for someone else's work. Of course, this is nonsense. Plagiarism and copyright infringement are two completely different things. Although they sometimes occur together, there are many examples of either without the other. And if your eyes just glazed over -- no problem: Nina Paley has made it easy with her new Minute Meme for QuestionCopyright.org, called "Credit is Due".

In the past I've already published articles and interviews on FSM about Firewall Builder (or FWB in short). The reason is simple: the tool kept evolving during the years, improving the features it already had and adding interesting new ones.
During these years I've not being using the tool regularly since I am not a Network Administrator. But I can say that every time I had a firewalling problem at hand, where I needed to prototype and test iptables configurations quickly, this tool never betrayed me!
This time we'll talk about how FWB helps you to configure multiple firewalls in a consistent way. We won't be talking about firewalling per se, so you can still benefit from reading this article even if you don't have deep firewalling, networking or security knowledge.
The examples in this article are based on Firewall Builder v4.2. NetCitadel recently announced the release of Firewall Builder 5 which includes some minor changes in the GUI, so some screenshots in this article may look slightly different from what you would see in v5.
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.
Adam is a Berlin-based writer and artist. Jonathan works at a not-for-profit organisation called the Open Knowledge Foundation and studies philosophy and intellectual history at the University of London. Together, they created a website called The Public Domain Review
Free Software and public domain are somehow cousins, and -- more importantly -- they share similar goals. I talked to Adam and Jonathan, who agreed to answer a few questions for us.
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.
My son has expressed an interest in getting into robotics as a hobby/learning exercise, which is pretty exciting to me, too. I want to get us set up to do some fun stuff, and I don't want things to be too hard so that we never really get started. One of the obvious choices for this is the Lego Mindstorms system, but the software that comes with it is designed only for Windows and Macintosh systems. Fortunately, there are free software alternatives. What will it cost in time and money to set up using our Debian GNU/Linux computers, and what will we get for that effort?
As you know I draw/produce the Bizarre Cathedral cartoon strips for Free Software Magazine. Lately you may have noticed it's slowed to a bit of a crawl and almost a halt. This is just to let you know that tBC has not ended and is forthcoming. Unfortunately I've had some personal stuff which has taken up more of my time than I wished.
The great guys at Packt Publishing just released the details for theirs 2011 Open Source awards.
We will forgive their embracing of the term "Open Source", especially since they've given _more than $100,000 for their awards.
The categories are:
At the beginning of 2011, the Falcon Committee decided to release version 1.0 of the Falcon Programming Language during the year. After a bit of discussion and planning, we begun working on a new version of the engine to support some constructs we wanted to add to the language: mostly rules and structured prototypes. Also, we spotted the possibility to add fuzzy logic and evolutionary programming (A-Life) constructs directly into the language. We now have a working prototype of what we’re calling the "Organic Virtual Machine".
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.
An Open letter to Sergey Brin, Larry Page, Matt Cutts, Vic Gundotra
Subject: So, does Google look into their users' private, non-shared files, and might close accounts if an AI decides that there is something illegal there?
Dear Sergey, Larry, Matt, and Vic,
Something sad happened to the world of cloud computing over the last week. I have followed with great interest the events of the now-celebrity @thomasmonopoly about Google closing his account.
Here is the short story: @thomasmonopoly had a bunch of (non-shared) images in his Google account. A program at Google flagged some of them as child pornography. His account was suspended. He complained loudly. He went viral. Google first ignored. Then backed their actions. They finally relented and apologised as there was no child pornography there, just an arts project -- a real one.
The Free Technology Academy  is one of those incredible initiatives that spring out of the free software culture, and create something that goes way beyond free software.
Unfortunately, the FTA has recently lost their European funding. I talked to David Jacovkis, one of the people behind this innovative project, to know more about their situation and what needs to be done so that their project can keep on thriving.
As far as personal computing, there has been a strong shift, in the last few years, towards multimedia contents. It started with digital cameras in phones, around 2003, which is when people really started taking a lot pictures with their phones, and started using their computers to organise them. They also started using MP3 players, and having to manage their music. If pictures and music weren't big and cumbersome enough, people also started managing their movie libraries (even though today a lot of people give up and opt for a cheap satellite TV subscription from sites like http://www.saveontvdirect.com/) instead, as movies still are too big to manage for a lot of people...
Inkscape is a shining star in the free software graphics world. I've covered creating a simple ribbon in an earlier tutorial, so let's step things up a little. As part of my work I have often had to create icons for various situations. One of the more popular requests has been to create icons with a glass effect. This effect is surprisingly simple to achieve with something like Inkscape.
The final step (and probably most interesting) step in creating my Lib-Ray prototype (for releasing high-definition video without DRM or other anti-features) is to make a disk menu system to access the video data that I've already prepared. This column will actually document my second prototype design, as opposed to the first prototype which I presented at Texas Linux Fest in April 2011. This second is a big improvement and conforms much better to the draft HTML5 standard from the WHAT Working Group, and is much more functional in the existing Chromium browser, although improvements are still needed.
Audacity is one of my favorite free software applications, and it has really improved over the years. This book covers the latest features in the 1.3.x series, which is expected to lead directly to the version 2.x Audacity. The book covers more than just Audacity, though. In the process of covering several different uses, it also discusses everything from hardware equipment selection to copyright and business problems that may come up in a project. Overall, it's a good read and a good introduction to Audacity, audio recording, and audio processing.
Sakai: Free as in Freedom, written by Charles Severance (the first Executive Director of the Sakai Foundation) is a personal view of the history of Sakai. The book is a thorough description of how the project and its software evolved. This is not a book about software configuration; it is a book that describes how a community emerged from the actions of individuals.
Unless you've been hiding in a cave for the last few years, you probably know about the free multimedia codecs with the fishy-sounding names from Xiph.org: Ogg Vorbis (for sound) and Ogg Theora (for video). You might be less familiar with other family and friends, including FLAC (lossless audio), Skeleton (metadata stream), and Kate (subtitles). However, together this collection of codecs can be used with the Ogg container format to provide all of the functionality of a DVD video file -- multiple soundtracks, full surround sound, high definition, and selectable subtitles. Having created the various streams for a prototype release of "Sintel" in my last few columns, I'm now going to integrate them into a single video file and test it with some players.
Recently I've seen a resurgence in chatter about Tilt-shift effects in photography. I think it has stemmed from the use of tilt shift in the introduction videos for the 2011 Eurovision Song Contest. Here I outline a brief tutorial in achieving tilt-shift miniaturisation effects using GIMP
