Donations play a crucial role in supporting Free and Open Source Software projects. At times readers will write in to share their positive experience with a utility or program or a distribution that I have written about. Now don't confuse them with your average technical-bent-of-mind Linux user. These are accountants, home-office businessman, and even carpenters and plumbers, who've saved a lot of money thanks to open source software. And they have one question in mind -- how do I help the person behind the program?

This month, Packt columnist and open source enthusiast Mayank Sharma explores the economics behind open source projects, what they do with their donations and how crucial they can be to their future.

Developers are free to set up an unlimited number of payment instructions. This makes it possible, for example, to have a different set of payment instructions for each counterparty with which you do business.

Developers can create payment instructions that are as simple or complex as they desire.  For example, creating a relatively complex business model around micro-payments is easy to do with Amazon FPS. Our aggregation feature lets you track and aggregate micro-payments into a single payment transaction, saving on transaction processing costs and avoiding having to build complex ledger functionality into your own applications.  Without this capability micro-payments would be difficult or cost-prohibitive.

Micro-Payments Support: With Amazon FPS you can track and aggregate micro-payments (e.g. payments less than $0.50 or even $0.01) into a single payment transaction and can charge the customer before (prepaid) or after (postpaid) the service is provided. This features lets you minimize transaction processing costs and avoid having to build complex ledger functionality into your applications.

Aggregate micro-transactions into a single larger transaction using Prepaid and Postpaid capabilities.

Exhibit is a lightweight structured data publishing framework that lets you create web pages with support for sorting, filtering, and rich visualizations by writing only HTML and optionally some CSS and Javascript code.

It's like Google Maps and Timeline, but for structured data normally published through database-backed web sites. Exhibit essentially removes the need for a database or a server side web application. Its Javascript-based engine makes it easy for everyone who has a little bit of knowledge of HTML and small data sets to share them with the world and let people easily interact with them.
...
Exhibit consists of a bunch of Javascript files that you include in your web page. At load time, this Javascript code reads in one or more JSON data files that you link from within your web page and constructs a database implemented in Javascript right inside the browser of whoever visits your web page. It then dynamically re-constructs the web page as the visitor sorts and filters through the data. As the visitor interacts with the web page, only the web browser is responsible for providing the interaction; the web server is no longer needed.
...
We also provide a complementary service called Babel that lets you convert data from various sources, including tab-separated values (copied straight from spreadsheets) and Bibtex files, into formats that Exhibit understands.

Exhibit currently only scales to a few hundreds of items, but maybe that's all you need. Furthermore, we are working on optimizing Exhibit and on ways for you to smoothly transit over to server-side solutions as your data sets grow.

YouLicense is an online music licensing marketplace. We have developed a platform which enables artists and those seeking musical content to conduct business directly with one another in a safe and secure environment. Our unique search engine and standardized contracts allow for a quick and easy process.

Whether you're looking to license music for Film & Television, Advertising Campaigns, Music on Hold, Mobile Phone Content, Web Content, Audio Projects, or you are a small business in need of musical content, YouLicense is your marketplace.

The world of music licensing is known to be complex, exclusive and expensive. It is often the case that those seeking to license music have great difficulty obtaining what they need and that only a small percentage of artists and composers have the means to offer their music for licensing.

Our aim is to break down these limitations and simplify the process.

YouLicense is non-exclusive and welcomes anyone with musical content to upload music and offer licenses for sale. This allows for a large range of musical content; from ringtones to sheet music to songs and beats; and is combined with a unique search engine to increase the chances of finding the much needed musical content.

VanFossen isn't referring to the kind of plagiarism in which a lazy college student copies sections of a book or another paper. This is automated digital plagiarism in which software bots can copy thousands of blog posts per hour and publish them verbatim onto Web sites on which contextual ads next to them can generate money for the site owner.

Such Web sites are known among Web publishers as "scraper sites" because they effectively scrape the content off blogs, usually through RSS (Really Simple Syndication) and other feeds on which those blogs are sent.

"It wasn't the issue of money," Leder added. "When other people's business model is based on stealing content, that's a significant problem."
