in house made library counters

LITA listserv exchange on “Raspberry PI Counter for Library Users”

I think that is a very interesting project.  If I understand how it works (comparing reference images to live images), it should still work if a “fuzzy” or translucent filter were placed on the lens as a privacy measure, correct? You could even make the fuzzy video publicly accessible to prove to folks that privacy is protected.

If that’s the case, IMHO, it really is a commercially viable idea and it would have a market far beyond libraries.  Open source code and hardware designs and sales of pre-packaged hardware and support.  Time for some crowdsource funding!  🙂

My note:
In 2018, following the university president’s call for ANY possible savings, the library administrator was send a proposal requesting information regarding the license for the current library counters and proposing the save the money for the license by creating an in-house Arduino counter. The blueprints for such counter were share (as per another LITA listserv exchange). SCSU Physics professor agreement to lead the project was secured as well as the opportunity for SCSU Physics students to develop the project as part of their individual study plan. The proposal was never addressed neither by the middle nor the upper management.

Python, Julia, Go, Rust

As Python’s lifetime grinds to a halt, a hot new competitor is emerging

other languages — the top players being Julia, Go, and Rust. Julia is great for mathematical and technical tasks, while Go is awesome for modular programs, and Rust is the top choice for systems programming.

Since data scientists and AI specialists deal with lots of mathematical problems, Julia is the winner for them.
