This gist presents part of my Scrapy NTK library: scraping_hub package.

Especialy this one might help you to communicate with ScrapingHub API. It provides set of classes build for fetching items from cloud.

Note: some of the imported modules are not included, but you can find them in my library on ni list of my gists.

Install PostgreSQL 10 on Ubuntu

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04 but likely can be used for Ubuntu 14.04 and 17.04 as well, with one minor modification detailed below.

(Optional) Uninstall other versions of postgres

To make life simple, remove all other versions of Postgres. Obviously not required, but again, makes life simple.

dpkg -l | grep postgres
