What's new in ES{5,6}
  • Block scopes with let and const
    • let in for loop rebinds variable on each iteration
  • lexical this (instead of dynamic one) with arrow functions
  • method definitions ?
  • shorthand object properties
    • var = {foo, bar}
  • computed property names
    • { [name()]: value }
  • getter & setter methods

Longest streak events

Here is a query adopted from blog.jooq.org:

explain analyze with
  dates(d) as
    (select distinct date(ctime)
      from "Event"
      where modelname='Partner'
        and type = 'Update'
        and userid = 193

  • technical debt is like a loan: the longer you have it, the worse it gets
  • Martin Fowler distinguishes
    • deliberate technical debt
    • inadvertent technical debt

Query that will benefit from grouping sets
with
events as
(select
modelid as ctr,
ctime,
(patch->>'isActive')::bool as isActive
from "Event"
where modelname = 'Contract'
and type = 'Update'
and (patch->>'isActive')::bool is not null
