Why the CSV standard library is broken (Part II) - The Wonders of CSV Formats
Hello, I’ve written a follow-up on why the CSV standard library is broken, broken, broken (and how to fix it).
Let’s have a look at the wonders of CSV formats / dialects such as MYSQL CSV export or PostgreSQL CSV or TEXT export. In a nutshell - the standard CSV parser is a (simplistic) kludge
using string.split() and, thus, needs to get replaced with a “real” parser that can handle more “edge” cases and formats. Questions and comments welcome. Cheers. Prost. PS: If want to see other (more) CSV formats / dialects pre-configured and supported “out-of-the-box” in the new csv reader, please tell.

What Options Can Be Passed to the Active Storage #variant Method?
When Rails adds a large new feature like Active Storage, it takes some time before good Internet resources and documentation become available for it. This can be a challenge when learning how to use the variant method for image transformations. Not only does it take a lot of options, but the format of those options isn’t obvious. To make it easier, check out the resources and tips I’ve compiled here: http://www.carlosramireziii.com/what-options-can-be-passed-to-the-active-storage-variant-method.html
