This question on GIS Stackexchange provides a good overview of why this is not as simple a request as you might think. Zip codes are created, maintained and updated frequently by the USPS (US Postal Service), not the census bureau. Their databases are not open or free.
However, if your previous dataset is from the 2010 Census, you probably don't actually ...

Railroads and the Making of Modern America has links to the following downloadable historical US railroad data. I didn't investigate the actual geospatial extent of these railroad datasets, so I can't promise they have Colorado railroads. Here's a wayback machine link in case the original site goes down.

I'm not aware of any such existing datasets, but you can make your own layer in either QGIS or Arc. Search for "create fishnets" in GIS Stack Exchange. BTW, a worldwide layer at your granularity will be immense, approaching 4 billion(!) polygons, which probably explains why you didn't find one. You may want to create such a layer at a regional scale ...
The links may help. The first is to the Douban Book Rating Dataset. It is the largest book review website in China. The second is a collection of Amazon ratings the was web scraped already by a user on Kaggle. Those are all I know of. Hope they help.
The Cauchy distribution has infinite variance, so you are not going to find simple, real world examples. However it is possible to mathematically construct examples.
The ratio of 2 normal distributions where the mean of the denominator random variable is 0 will follow a Cauchy (or at least Cauchy like (it has been a while since I was in ...
You can see daily precipitation summaries for specific observation stations on NOAA's Climate Data Online Mapping Tool. I tried to link you directly to the precipitation map for your area of interest, but that doesn't seem to be possible. Here's how to get to the data you want:
Use the rectangle select tool to see the stations in your area of interest.

The EOL traitbank can be queried by API, and it's also possible to ...
