Applied Nate Silver – another statistics issue

As you know from all my other posts to you my digital scale has considerable variability and I’m trying to figure out how to deal with this. Need some help here, Nate (you seem to be ignoring my previous pleas … Continue reading

Met an extraordinary fellow

At Starbucks today I noticed a very fit fellow with pack and hiking poles and then noticed the banner on his pack that he’s hiking from NYC to LA to aid the Diabetes Association. We had a pleasant and interesting … Continue reading

Applied Nate Silver – stuck in the ’90s (but moving now)

Last week I was complaining about being stuck in my weight loss trajectory and responded by my most extreme dieting and exercise yet and thus did finally break through, but with some strange results. Let’s just start with the usual … Continue reading

Amazing Curiosity picture

I’m glad they got this picture before Curiosity breaks. NASA has been taking its sweet time getting up Mt. Sharp and now their computers are breaking. Hopefully they’ll pick up the pace and get climbing. This is a great picture … Continue reading

QuickReaction, Sunday-7

So much for the waste in Iraq: All those lives, all that treasure, and now we see Iraq is helping Iran arm Syria and prop up Assad. Oh goodie, so much for George Dumbya Bush’s and the neocon’s brilliant foreign … Continue reading
