This is my technical interview cheat sheet. Feel free to fork it or do whatever you want with it. PLEASE let me know if there are any errors or if anything crucial is missing. I will add more links soon.

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

You could have postgre installed on localhost with password (or without user or password seted after instalation) but if we are developing we really don't need password, so configuring postgre server without password for all your rails project is usefull.

Install Postgre packages

  • postgresql
  • postgresql-client
  • libpq-dev

Quickstart ELK on local machine.
1) Download Kibana ( good versions for communication with elasticsearch 2.#, it is https://www.elastic.co/downloads/past-releases/kibana-4-3-3 or https://www.elastic.co/downloads/past-releases/kibana-4-4-2 )
2) Download Logstash we can use logstash 5.0.0 because version of logstash does not depend from version Kibana or ElasticSearch. You can download package from brew or archive from official elastic site.
3) Next step is a bind Kibana with elasticsearch. After you unpacked Kibana archive,
$ cd /kibana-4.3.3-darwin-x64/config
$ atom kibana.yml
And uncomment this line and save.
# The Elasticsearch instance to use for all your queries.
