Installing Ruby and Hobo on a fresh Ubuntu Machine

This way several ruby versions can be installed individually and it's easy to switch between them.

Installing prerequesties

sudo apt-get install bash curl git-core build-essential bison openssl libreadline6 libreadline6-dev zlib1g zlib1g-dev libssl-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev curl git-core libyaml-dev libxslt-dev autoconf libmysqlclient-dev libreadline5 libltdl-dev libncurses5-dev libserf1-dbg libsvn1 libtool subversion libgdbm-dev pkg-config libffi-dev@

This is a short recipe how to add the functionality to a Hobo powered Rails application to login via access to an email address.

Disclaimer:

I thought about security concerns regarding this.

The only drawback compared to an application that lets you change a forgotten password is that this way, you wouldn't notice if somebody logged in with the stolen login link, because there is no need for a password change.

I'm no security expert. If you are :-), feel free to add comments to this gists, that help me improve security.

I have got a Webshop applacation with a structure of 1700 products in 400 product categories through categorizations, and 1600 product properties in 1100 property groups and their 105 000 values.

For filtering and wanted to have a facetted search on category level on the values, like in the screenshot in the file facets.png

In the /Gemfile I load the Searchkick Gem:

gem "searchkick"                                    # Elastic Search integration

A few weeks ago I posted about a poor man's chat server I created with Hobo's Ajax features. I now had the request to improve performance, so I tried to fix it.

I pimped my old solution with a Faye messaging server: Ryan Bates created a gem and a Railscast about it.

Lets see how we update data on all connected clients but only when necessary. In conversation.dryml we subscribe to a faye server:

<%= subscribe_to "/conversations/" + this.id.to_s %>

• Got the CSRF knowledge from: FineUploader/fine-uploader#104

Works also on Linux Mint LMDE, see Guide for details. Even if I got everything running, I'm still prefering to deploy to my own servers, it was a hassle. Sometimes deploying free applications is dead slow.

• Installing the Heroku on Ubuntu wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh
