   Postgres 9.4+ lets you use the write-ahead log and "replication slots" using which you can create streams of database changes that can be replayed to a client in the order they were made on the origin server [1] EDIT: In case the

   I recently had to build a product search functionality. I was able to pick up nearly all important features of Elasticsearch in about 2 days and had live-indexing and search up and running within 2 more days. Of course, this wasn't pro

    Csv is an ubiquitous data format. Especially when you're receiving data from external sources which you don't have control over, which often happens to be the case in banking and finance (streaming csv dumps are quite common)

    I've been writing q code for more than 6 years now. It's definitely possible to write code which doesn't look like line noise. It's easy to build an automated testing layer on top of your q codebase too (via the c or Jav
