Software Sharing for Modern Businesses.
Engage the developer community with your company's core software products. Fair Source Software (FSS):
- is publicly available to read;
- allows use, modification, and redistribution with minimal restrictions to protect the producer’s business model; and
- undergoes delayed Open Source publication (DOSP).
The intention is for the first point to be a bright line, and for the second to invite exploration. We expect Fair Source licenses to emerge and evolve and shake out into a few clear winners over time, as companies apply Fair Source within their own particular business context.
NASA and IBM have teamed up to create an AI Foundation Model for Earth Observations, using large-scale satellite and remote sensing data, including the Harmonized Landsat and Sentinel-2 (HLS) data.

A general situation that we all might face while going through websites/apps is to wait for some progress or something to get loaded. A most simple solution in such scenarios is to use a loader or spinner to indicate users that something is loading in the background. Considering this, I tried to create a library having a collection of such loaders/spinners. There are no image dependencies for this library. It's developed using pure CSS. Hence it will load fast and is easily customizable too.
