hn job query search
// Usage:
// Copy and paste all of this into a debug console window of the "Who is Hiring?" comment thread
// then use as follows:
//
// query(term | [term, term, ...], term | [term, term, ...], ...)
//
// When arguments are in an array then that means an "or" and when they are seperate that means "and"
//
// Term is of the format:
// ((-)text/RegExp) ( '-' means negation )

  2. Models and Issues in Data Stream Systems
  3. Philippe Flajolet’s contribution to streaming algorithms : A presentation by Jérémie Lumbroso that visits some of the hostorical perspectives and how it all began with Flajolet
  4. Approximate Frequency Counts over Data Streams by Gurmeet Singh Manku & Rajeev Motwani : One of the early papers on the subject.
