IBM today made some mainframe moves, unveiling a new System z10 machine and, along with it, software and resources to help educate programmers about how to more easily develop, administer, automate and deploy mainframe applications. Lenovo strikes up a challenge for Apple in the form of ThinkPad X300, which it claims is more feature-rich than Apple’s MacBook Air, while still pushing the envelope of lightweight ultraportable PCs. On the full-size notebook front Apple, for its part, unveils pumped up MacBook and MacBook Pros, adding bigger hard drives and 45-nanometer Penryn chips. (Thanks to Computerworld for that last one.) Sun Microsystems CEO Jonathan Schwartz talks up MySQL as the acquisition closes, saying that the open source database is not only a perfect fit in terms of culture, business and technology, but also the most important purchase in Sun’s history. Network Solutions faces a class-action lawsuit alleging that it has unfairly profited from its questionable practice of automatically reserving a domain name once someone runs a search on it. And a Google official, speaking at the Adobe Engage conference, says that Google’s fate is tied to the Web, and that is exactly why the search company is working on social networking initiative, applications and platforms.
