While there have been some questionable strategies playing out on Wall Street recently, and the Securities and Exchange Commission continues to scrutinize the legalities of a few high frequency trading techniques, former NYSE chairman William H. Donaldson's statement to New York Times holds true: if an individual investor can't keep up with larger brokerages, it's a major disadvantage.

Marketcetera feels that open source software is an ideal way for smaller brokerages to keep up with -- and perhaps outmaneuver -- their larger competition. Marketcetera CEO Graham Miller sees open source hosted/SaaS (software as a service) trading platforms as having particular potential for investors using high frequency trading methods. And Miller isn't the only one who believes this -- the evidence is vibrantly illustrated by Sky Road LLC's integration of Marketcetera's open source, automated trading platform into its SaaS financial services product line.

The financial services market is still a largely uncharted region for open source software. Sure, there are several Exchanges around the globe that use Linux to power their operations, but the minds, the people, and the currency that bring life to the trading floors don't operate solely on a patch of real estate in New York, London or Hong Kong. Marketcetera is one of the first open source software vendors to blaze a trail in this industry, with its open source trading platform catering to buy side and algorithmic trading.

Tackling a new market often necessitates a new way of thinking and looking at problems, but having experienced advisors onboard is still crucial to successfully navigate the unfamiliar territory -- for the insight they give, and the assurance their presence can instill in potential customers. This is only one of the reasons Marketcetera is welcoming Larry Stefonic to its advisory board. Stefonic is no stranger to the software industry, having co-founded the yaSSL project, an open source internet security suite, holding management positions at Centure Software, Raima Corporation and recently serving as the executive vice president of sales at MySQL AB.

The Marketcetera team is as aware as the rest of us that economic changes are coming fast and furious, and that open source software can have an impact on a company's -- or individual's -- financial future. Honestly, one could say Marketcetera is twice as aware of open source software's financial potential.

Today, Marketcetera released the first full production release of its open source automated trading platform. Aimed at hedge fund managers, traders, brokers and dealers, the system is standardized, open, scalable and modular. This, says Marketcetera CEO Graham Miller, offers users faster deployments, better integration, and the ability to customize everything from the public APIs to data models.

Since acquiring the Koders.com code search engine earlier this year, Black Duck Software has added more than 200 million lines of code to the Koders.com search repository. Black Duck says that an analysis of search requests reveals, Ruby is now the fourth most requested language on Koders.com, after Java, C/C++ and C#. That's interesting information, to be sure, but what does it mean?

Apache fans in the Ruby community were delighted several months ago, when Phusion released Passenger, an Apache module for deploying Rails applications. I have been working with Passenger over the last few weeks, and am pleased to report that the module is extremely easy to install, use, and configure. Passenger has succeeded in bringing me back into the world of Apache after several years of wandering in the HTTP server desert.

When you're working with a commercial software company, it's easy to keep up with their latest news: Between the company's Web sites, e-mail newsletters, conferences, and (increasingly) blogs, you can find out what is happening, and prepare yourself accordingly. Life in the open-source world is quite a bit messier, of course, in that there often isn't any central location or source for news. One of the key tools that the open-source community uses to keep in touch is blogs -- but it's not always easy to find all of the blogs on the subjects that interest you. That's where blog planets come in, providing a one-stop aggregation of many blogs on a particular subject.

Want to learn a new programming language or development framework? Books, magazines, and blogs are excellent -- but a growing number of people are also learning from screencasts, tutorials that combine someone's voice with a video of their computer screen. You can watch the teacher develop in real time, describing the actions that he or she is taking while they take place. There are many screencasts for open-source languages and frameworks, many for free and some for a nominal fee. Screencasts are playing a growing role in my attempt to keep up with new technologies, and you might well find them useful, too.

Last week, members of the Ruby community received word that all but the most recent versions of the language contain a serious security hole, and should be upgraded immediately. The announcement indicated that the security problem allows an attacker to potentially execute arbitrary code from a remote location. Other than that general description, what is the problem? Well... the powers that be aren't telling. Zed Shaw, decided to blog about this, announcing the vulnerabilities, as well as the techniques that he used to uncover them.

One of the fascinating trends that the Java world has seen in the last few years is the growth of non-Java languages that use the JVM (Java Virtual Machine). After all, if you create a new programming language, you will need to write it for a particular platform. If you want your language to be portable across platforms, you will need to implement versions for each of those platforms. By contrast, if you implement your language on the JVM, then your language will work on any system with a JVM, which is basically everywhere. Four of these languages -- Jython, JRuby, Groovy, and Scala -- are released under open-source licenses, and are increasingly popular choices for programmers who value portability.
