    Proposed compiler and language changes for GHC and GHC/Haskell

    I am eager to write strict Haskell. I understand the the -XStrict and Unlifted datatypes help with this. Actually it is interesting that -XStrict does not really cut it, we need unlifted datatypes..

  • containers

    Assorted concrete container types (by haskell)

    "Make invalid laziness unrepresentable" means you should use strict versions of container types instead of lazy ones. However, for better or for worse, sometimes the "strict version" of a data type is not actually a strict data type, it's just a strict API to the lazy type. Examples include Data.Map.Strict (not Data.Map or Data.Map.Lazy) or Data.HashMap.Strict (not Data.HashMap.Lazy) (sadly there is no Data.Sequence.Strict but perhaps there will be one day).

  • InfluxDB

    Access the most powerful time series database as a service. Ingest, store, & analyze all types of time series data in a fully-managed, purpose-built database. Keep data forever with low-cost storage and superior data compression.
