1. : Microsoft submitted driver source code for the Linux kernel under the GPLv2 license in a move that, as the headline says, stunned the open-source community. Although it didn't take long, as is noted in our fourth entry below, for Microsoft's decision to be called into question.

2. : A convoluted network of companies has promised to launch through Zer01 Mobile the service of our dreams, including unlimited Internet access, phone calls and texting for US$70 a month. The service was supposed to launch July 1 but didn't, and digging into Zer01's claims raises a lot of questions about the people behind the company and its affiliated firms, and whether it is even possible to do what Zer01 says it is going to do.

3. : Microsoft will offer a choice of browsers with the Windows 7 OS to appease European Union competition regulators, who say they welcome the company's proposal and will look into "its practical effectiveness in terms of ensuring genuine consumer choice." We'll let you know what they decide about that.

4. and : Three days after Microsoft released that driver source code for the Linux kernel, an open-source engineer said that the code was in violation of the GPL, and he offered details in a blog for how the violation was uncovered. Microsoft responded that it did not release the code because of any "perceived obligations" to the license, but because the license is preferred by the Linux community and the release benefits Microsoft customers and Linux users. We doubt we have heard the last of this.

5. and : It was a bad week for Adobe and its users because of exploits found in the company's software, and next week does not look to be any better. Security companies warned that Acrobat Reader and the Flash Player will continue to be vulnerable to a zero-day exploit that is rated "highly critical." Adobe is working to get a patch out by next Friday.
