Big news. The years-in-coming “Truly Ergonomic Keyboard” has arrived. This just might prove to be the ultimate emacs keyboard.

Python vs Lisp: comp.lang newsgroup spittle
On 2011-12-04, Eduardo Costa asked in comp.lang.lisp:
I pose the questions below out of sheer curiosity, not to cause outbursts of indignation. That said, here are my questions.
… I noticed that many LISP programmers and universities are switching to Python, even to teach AI. For instance, Norvig and the people at MIT replaced Scheme with Python. My own experience with Python was dismaying. The language is much slower than SBCL. There is no tail call optimization. No macros. Then, my first question is ... Why Python?

… Python has more readable syntax, more modern computer language concepts, and more robust libraries. These qualities in turn made it popular.
Tim Bradshaw wrote:
Yet you still post here [comp.lang.lisp]: why?
i don't like Python, and i prefer emacs lisp. The primary reason is that Python is not functional, especially with Python 3. The Python community is full of fanatics with their drivels. In that respect, it's not unlike Common Lisp community and Scheme lisp community.

Microsoft Discontinued SideWinder Gaming Mouse X8
It looks like Microsoft has discontinued its SideWinder Gaming mouse X8. It's quite a pity. This mouse was just introduced in 2009, with several advanced technologies. • Charger with magnetic connector. • Wireless. • Blue laser tracking. • Tilt scroll wheel. • 4000 DPI. For review, see: Microsoft SideWinder Mouse Review.
According to online rumors, Microsoft discontinued it not because of poor sale, but rather, too much competition from many companies that are dedicated to gaming devices. It appears that Microsoft has discontinued the entire SideWinder brand. (i wasn't able to confirm this 100%) Some of the models such as SideWinder X8 mouse are no longer listed on Microsoft's site, but they still sell some other models of gaming keyboard and mouse.
