This post is just some fascinating (or quite boring depending on your perspective) minutia that arises in the handling of time and timezones in programming. This deals with a little corner that exists in almost every time library yet I’ve never had much reason to explore it. That little corner is daylight savings time transitions.
About 5 or 6 years ago, I decided to form better sleep habits. Included in that was a committment to try to sleep for at least 8 hours every night. It is a committment I struggled with for quite some time. In recent years, though, I seem to have adapted to a more consistent sleep schedule. I'm also fortunate that activity trackers, like my Garmin watch, are able to record sleep related data each night. In this post, I export all of my 2019 sleep data from Garmin Connect and use it to determine how well I'm sleeping and what else I might do to sleep better in 2020.
The only paper periodical that is still delivered to my house is MIT’s Technology Review. In the back of every issue, there is a section called Puzzle Corner. The column consists of densely packed reader-submitted math puzzles and solutions to puzzles published in earlier editions. Recently, I enticed my daughter, Zoe, into solving one of the problems with me. This is a summary of our adventure.
We recently solved the mystery behind a pattern of failures that have been happening very infrequently over a long period of time. The culprit turned out to be a very suprising bug in PHP's MySQL driver, so I thought it might be worthy of a public blog post.
