Musings about office technology from an intellectual property lawyer
Over and over again I somehow stumble upon or learn about a thing that seemingly almost everybody else already knew. Today’s question is, why are shower head nozzles flexible? You probably already know why, in which case please post a comment below. Anyway, here is what I figured out about flexible shower head nozzles.

I am intrigued to hear about a WIPO initiative called the “Global IP Assignment Platform” (GIPAP). I suggest that interested practitioners and IP owners register for one of these upcoming WIPO webinars. Continue reading “Global IP Assignment Platform (GIPAP)”
It will be recalled (blog article, April 30, 2026) that recently I had a luggage tracking tag get knocked loose from my suitcase and the tag ended up at an airport in Portugal. Thanks to comments from loyal readers, I was inspired to try harder on this. Continue reading “New effort to secure a luggage tracking tag”

Actually the suitcase is with me right now at home in the mountains of Colorado. What explains this? Continue reading “My luggage tracking tag ended up in Portugal”
Recently I added an environmental sensor to a rooftop solar meshtastic node. This provides telemetry of temperature, humidity, and barometric pressure. In this article I describe what was required to accomplish this. Continue reading “Adding a barometric pressure sensor to a Meshtastic rooftop solar node”
Recent news articles talk about instances where Anthropic’s Mythos AI is said to have found software flaws in pieces of software that have been around for a long time. The pieces of software in which Mythos has been said to have found flaws were each from the open-source community.
What should we, as readers and users of software, make of this? What should we do differently? Should we avoid open-source software? In this blog article I offer my thoughts. I do think there are things that we, as readers and users of software, should do and not do. But avoiding open-source software is not among them. Continue reading “What to make of the threats from AI that jeopardize software that we all rely upon?”
I must confess I was not aware, until a few moments ago, that there was such a thing as a World Quantum Day.
You can see the Wikipedia page about World Quantum Day.
You can see a nice video with some fun facts about quantum physics.
Many long-time readers of this blog will recall the anxieties leading up to the year 2000. The worry was that some software systems, to squeeze more information into less memory, were storing only the last two digits of the year instead of storing all four digits. The worry was that when January 1, 2000 arrived, some systems would crash or calculate things incorrectly. This was called “the Y2K problem”. And now we have an example of a sort of Y2K problem with gasoline pumps. Continue reading “Sort of a Y2K problem with gasoline pumps”
