    Kotlin Dataframe

    Kotlin Dataframe

    Structured data processing in Kotlin

    Data frame is an abstraction for working with structured data. Essentially it’s a 2-dimensional table with labeled columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dictionary of series objects. The handiness of this abstraction is not in the table itself but in a set of operations defined on it. The Kotlin Dataframe library is an idiomatic Kotlin DSL defining such operations. The process of working with data frame is often called data...

    safe and easy casting from one type to another in Go

    ...Rather than relying purely on raw type assertions, it offers ToInt, ToString, ToBool, ToTime, etc., and their “error-returning” counterparts like ToIntE. It is particularly useful when dealing with data from YAML, TOML, JSON or other formats where the type can be uncertain. The design choice is to avoid guessing about conversions: e.g., only a string strictly representing an integer can convert to int. The library is mature, tested, and widely used—thus ideal for projects that must handle dynamic input gracefully.
