* Getting started with a new platform. For example, describing the problem, and having it create a template in a front end framework, CSS framework, API generator.

* Creating instructional materials. Pasting in code and generating explanations, assessments, and grading rubrics. [2]

* Generating the first pass of API documentation, READMEs, test suites, and configuration files. Modifying configuration files. Finding configuration options based on NL descriptions.

* Quickly generating examples of API uses that are specific to my application. Finding out what libraries and APIs are available for a use case, based on an NL description.

* Learning what algorithms exist for a problem. Generating implementations of these in different languages, or that are specific to my code or data structures.

* Rarely-used system administrations commands. For example, how do I flush the DNS cache on macOS Safari and Chrome? (Questions such as this are actually better on Perplexity.ai than on ChatGPT.)

* Pasting in error messages or descriptions of problems, and asking for solutions.

* Tie-breaker questions about what to name a file, function, or set of functions.

In general, I find that it takes a lot of the drudgery out of programming. (Similar to Copilot, but for a different, generally more macro, set of areas.) For example, I asked it to solve a geometry problem and generate a test harness for both interactively and batch testing it. It's solution to the problem itself was a non-starter, but the test harness was great and would have been involved boring work in order to write.

I also use it to generate emails, project proposals, feedback, etc. I don't think it's ever come up with anything usable, but seeing what's wrong with its attempt is an easier way for me to get started than looking at a blank page or searching for examples of the writing form on the web are.

The Zoom app, and the Logitech C922, each have live background replacement ("virtual green screen").

For post-production without a physical green screen, you can use a green rectangle as your virtual background in Zoom or with the Logitech, import into iMovie etc., and chromakey there.

The drones carry loudspeakers which announce: “Please stay at home as much as possible. If you have to go out, don’t forget to wear a mask.”

The drones can also scan car plates and record which vehicles have entered the community.

The drones are also equipped with thermal scanners which can measure the temperatures of people idling in the community.

Those found with normal temperatures will be encouraged to return home. Officials will be alerted of people found with fever."

I remember reading in the local paper that you have to register with the pharmacy in order to buy fever medicine but I can't find an online source now and I haven't been into a pharmacy to observe it myself.
