Google announced Buzz today, as we anticipated this morning. CNET has a workmanlike description of the social-networking service, which is integrated into gmail. CNET identifies a central obstacle Buzz will have to overcome to gain traction: "The problem, however, will be the increasing backlash Google is seeing from the general public over how much data the company already controls on their online habits." Buzz is being rolled out over the next few days so some people will see a Buzz folder in their gmail, but most won't yet (this Twitter post explains how Safari users can get an early glimpse). A blog posting up at O'Reilly Answers points out some of the distinguishing characteristics of Google Buzz — one interesting one being its ability to post an update either publicly or privately, at the user's option. This design choice places it between the public-by-default Twitter and the private-by-default Facebook. Lauren Weinstein sounds a note of caution about the inherent privacy risks of Google's method of filling out initial friend profiles by automatic friending.

If Lee's blog post is to be believed, Apple plans to sell nearly twice as many tablets as it did iPhones in the product's first year."

As one of the comments puts it, this adds a "Time Machine-esque" function to Solaris, through which a user can specify backup frequency, and when needed browse from available snapshots to restore files.

Macthorpe writes "BetaNews is reporting that Microsoft has announced in a letter that they will support ODF as a format option, if it doesn't 'restrict choice among formats'. Citing their lack of opposition to the ratification of ODF as a standard, they go on to say: 'ODF's design may make it attractive to those users that are interested in a particular level of functionality in their productivity suite or developers who want to work that format. Open XML may be more attractive to those who want richer functionality [...] This is not to say that one is better than the other — just that they meet different needs in the marketplace.'"

PCM2 writes "It's not Oracle Linux, but Larry Ellison has announced that Oracle will be providing full enterprise support for Linux. This means not just phone calls but also patches, security fixes, and backports, in addition to indemnification from lawsuits like SCO's. This puts Oracle in direct competition with its erstwhile partner, Red Hat, whose entire business is based on providing similar support for its Linux distro and related software."
