HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on

     opts[:max_dataset_size]
    
     It is a very important constant that provides a useful performance optimization.
    
     For example we have N records in `users` table and want to show that number
     under the corresponding table on `/users` page. It would be quite fast for DB
     to count some tausands records and return that value back to the application.
     But in case of 1M records the same task will load the DB server significantly
     and without the relevant reason. There is no difference for web-app purposes
     whether we have 1M or 1M+1 records in the DB .

Super fast, keyboard-optimized, client side Hugo search

This is a fork of and builds upon the work of Eddie Webb's search and Matthew Daly's search explorations.

It's built for the Hugo static site generator, but could be adopted to function with any json index compatible with Fuse fuzzy search library.

To see it in action, go to craigmod.com and press CMD-/ and start typing.
