2020 Miles

With yesterday’s ride in the books, I’ve now hit 2,020 miles riding for the year 2020. I’m now at 2,039 miles ridden both outdoors and on the trainer for this year. Just a fun number. If VeloViewer is to be believed, I will end up with something north of 4,000 miles of riding for all of 2020. However, I think that presumes I keep up my outdoor riding pace the last two months during the cooler months of November and December on the indoor trainer. I..suppose that could happen. ...

June 2020 Month in Biking

Good month! Worse than May, unfortunately. A few less miles, almost two fewer hours, and almost 2,200 feet fewer! What was I doing?? ...

Sore Today, Gone Tomorrow?

The long ride in the heat yesterday is certainly taking it’s toll. Water On the plus side, I’m not at all dehydrated! No headaches after the ride or this morning, which is something I’ve encountered when out riding in the heat and not drinking enough liquid. I consumed ~4 bottles of water during the ride (out for 4:30) and then at least 4-16oz glasses throughout the day once I got home. Plus beer. ...

Programmatic Solutions to Miracle Sudoku

This blog from benjamincongdon.me is really interesting. It demonstrates how to build a Miracle Sudoku solver using Prolog, which is a logic programming language written in a declarative syntax. It’s incredible how concisely a solver for Sudoku puzzles can be written in that language! What’s remarkable about these solvers is how they can tell you interesting facts about puzzles such as the Miracle Sudoku: The minimal number of hints necessary to uniquely define a solution board is 2. Boards with just 1 placed hint have 8 solutions, always – no matter which digit the hint is or where it’s placed. There are many, many valid 2-digit hints. For example, there are 2320 ways to place a 1 and a 2 on the board which lead to a unique solution. Since there are only 72 unique solution boards, you’d run out of interesting solutions before you ran out of hints. ...

Weasels have eaten our phone system

For about an hour on Tuesday night, Citibank customers trying to phone the company were met with the same odd message in place of a polite automated service operator: “Hello world. Weasels have eaten our phone system.” I think the best part is the reasoning why. Open source software, a dedicated contributor from 15 years ago paying to record joke messages, and a large company using something for free and being “bitten” by this joke/bug. It hits all the right notes for me. ...
