Financial terms, first reported by The Deal, were not disclosed. That said, when rumors of the acquisition began circulating in October, the purchase price was said to be $60 million.

Writing in a company blog post, Microsoft corporate VP Brad Anderson said Opalis is an essential piece of Redmond’s “dynamic data center initiative.”

“This deal brings together the deep datacenter automation expertise of Opalis with the integrated physical and virtualized datacenter management capabilities of Microsoft System Center. I believe Opalis’ software together with the System Center suite will improve the efficiency of IT staff and operations, and customers will gain greater process consistency. Opalis’ software captures the IT processes, in a documented and repeatable way, which can be run over and over again. These capabilities will be added to Microsoft System Center to help customers automate complex IT processes, increase cost savings and shorten timeframes for IT service delivery across physical, virtual and cloud computing environments.”

CAPTCHA, for those of you just joining us, stands for Completely Automated Public Turing test to tell Computers and Humans Apart. Essentially, it’s a challenge-response test used to distinguish between humans and spam-spewing robots. What’s interesting about reCAPTCHA’s implementation is that it’s used for digitizing books.

“Since computers have trouble reading squiggly words like these, CAPTCHAs are designed to allow humans in but prevent malicious programs from scalping tickets or obtain millions of email accounts for spamming,” Google explains in a post to the company blog. “But there’s a twist–the words in many of the CAPTCHAs provided by reCAPTCHA come from scanned archival newspapers and old books. Computers find it hard to recognize these words because the ink and paper have degraded over time, but by typing them in as a CAPTCHA, crowds teach computers to read the scanned text.”

An ingenious idea, crowdsourcing book transcriptions in this way. An effective one too: reCAPTCHA boasts 99.5 percent accuracy at the word level.

Little wonder, then, that Google (GOOG) has acquired it. The company can clearly put reCaptcha’s technology to good use, not just as a security measure, but as a means of improving its own massive book-scanning project.

Now, Mini-Microsoft is not an official company blog, and it’s penned by an anonymous author. So the layoff rumor it’s floating should be viewed as just that, a rumor. That said, the blog has long been a clearinghouse for internal information Microsoft would much prefer to keep under wraps–and a fairly accurate one at that. So it’s certainly worth paying attention to. As Joe Wilcox writes over at Microsoft Watch, “When Mini speaks layoffs, I believe.”
