Next week the KNIME fall conference will be happening, Nov 14-16. For mathematicians or anyone wanting to look at some useful AI/Machine learning tools, this should be an informative conference! I’ve seen some previous sessions with interesting demos and overviews of new features they add to this open-source tool. Virtual passes are free to the live-streamed event! If it is like past online lessons, it is likely they will also be available later from their Youtube channel page.

There have been a lot of items in the news about electric cars recently – many states have rebate for new vehicles, and federal tax incentives will be a complicated and interesting opportunity next year. The car company website would certainly say you will save a lot purchasing their vehicles, but there is a surprisingly easy way to estimate for yourself whether an EV is cost effective.

Both Matt Parker and the Youtube Veritasium channel have reviewed the surprising best practice for the 100 prisoners puzzle. The puzzle is a way to find a solution that will let the prisoners win with the most probability. If you have not seen this already please see the video here before some spoilers below.
