If you’ve seen any behind-the-scenes view of any movie you probably are familiar with the green-screen – generally a way to combine an actor with some prerecorded or computer generated background. There are some unique effects you can do with this yourself using OpenCV!

In recent years there has been a lot of talk about solar and more renewable energy. In USA the recent IRA has provisions for extending solar and renewable energy, and the Florida governor last year supported Solar benefits which turn out to be helpful in many natural disasters, making an energy grid more easily self-sustainable after hurricanes that are common to that state. What if we could go over a map and see what buildings are the best candidates for solar generation? OpenStreetMap has not just street maps, but many other features, including building coordinates, which can give us polygons that can calculate areas for potential solar!

Recently it was noted, by Arstechnica and others, that ChatGPT doesn’t seem to be great at math questions – recent tests have found one can get wrong answers much more often than a calculator, and even apologize if you insist that it is wrong (suggesting it doesn’t know math after 2021… lol). but what about other similar assistants?

In recent months, new inventions like ChatGPT have been said to be possibly the end of society, or the saving of society… but maybe this is something that is something very similar to what has been hyped before?

If you have been experimenting with the widely used OpenCV project, you may have found the StereoSGBM functionality that tries to find the difference between two images to find depth!

In a previous post I showed some interesting facts about Zipf’s law and how many different things show a pattern of logarithmic decrease with the most popular or numerous item largely being much more so than the very rare ones – in a logarithmic pattern. Let’s look at that pattern and how you can chart it…
