I poured myself a day-drinking celebratory Maker’s 46. Now to get the house ready for company.

I've just sent my 4-year tenure review dossier to my department chair. God, that was a lot of work. My teaching portfolio clocks in at 560 pages. Hey, they wanted me to document everything, so they got what they asked for. I've done a lot of stuff that I’m proud of, and since I'm on a special title series with emphasis on teaching, it is as it should be.
Now I'm ready for the Super Bowl. Gotta start these wings soon. Looking forward to a good time with family and friends.

The girls had fun at the Hadestown musical at the Lexington Opera House tonight. I used the quiet time to work on my tenure dossier and watch some #CornerGas
Fun was had by all for some definition of fun.

Well, here we go. #UKY will be closed tomorrow, again. The overnight low is forecast to be 3 ºF (that's -16 ºC for you sane folks). Wind chills well into the negative numbers. Power is stable, but I think at this point we'll have to worry more about the water pipes. Stay warm and safe, y'all!

I do disagree. Altman never completed a STEM education, and Musk has a BA in physics and an MBA. Also not exactly STEM, certainly not at a graduate level. But more to the point, every accredited STEM program has a mandatory ethics and standards component,which heavily draws from the humanities. And GenEd requirements have always been in place. These people just chose to ignore that part of the curriculum or were never even exposed to it.

The line at the #Feuerzangenbowle was short, because nobody knew what it was. Sonee advertised for them and got them some customers. They were very grateful and gave us some free mugs and threw in a sugar cone, which are hard to get here. Fun times!

The Rathskeller had a nice ambience. Food was OK, but of course as Germans we always compare it to home cooking and so we tend to be overly critical. Overall a nice first stop. Now on to Carmel.

I was vaguely aware of the symbol grounding problem. I think I remember that Winograd and Flores did come to roughly the same conclusion in “Understanding Computers and Cognition”, in that it really boils down to the imprecision and limitations of natural language and that humans are limited to express thoughts in it. Now I want to re-read that book, it's been a long time.

Well, to his credit, I think he does point out the "enigmatic nature" of those systems a couple of paragraphs later:
“That lack of real-world grounding is not desirable: No one likes the enigmatic nature of these AI systems, and scientists are eager to understand better how they work.”

When we came to the US in 2002, I couldn’t believe how ubiquitous and cheap,sole was compared to Germany, even here in Kentucky. That ceased to be the case around 2010 and I haven’t seen it here in a long time, either. My in-laws live at the North Sea coast, and even there in restaurants you pay a hefty premium if you can get it at all. Probably a combination of overfishing and climate change. Sad.

So for my cryptography class, I decided to recreate the famous distorted Tux image encrypted with a block cipher in electronic codebook mode. I used OpenSSL to encrypt the bitmap file using aes-128-ecb. I replaced the encrypted BMP header with the original one (using a hex editor or the good old dd command), and voila, mission accomplished. I'll probably make this into a video for my YouTube/PeerTube channels. That was fun.
