Showerloop

REAL-TIME FILTRATION, PURIFICATION & RECYCLING  SYSTEM FOR SHOWER WATEROPEN SOURCE – OPEN HARDWARE – ECOLOGICAL – ECONOMICALShowers are great, but pouring hot and almost drinkable water down the drain is not. Besides the obvious costs to the environment and your bills, there is also a conscious on unconscious psychological cost any time you create waste. To solve this problem we created Showerloop. It’s a shower that collects, cleans and reuses the water in real time while you are showering. So now you can shower for as long as you like without wasting precious resources.SHOWERLOOP VS NORMAL SHOWERNormal ShowerShowerloop90% reduction in water usage and 70-90% in energy reduction for a 10 minute shower with a flow rate of 10 l/min. Savings are dependant on user behaviour and can vary. Use Just one bucket of water for a shower of any length.  See the savings section for more information.

MySql JSON support!

JSON support. Beginning with MySQL 5.7.8, MySQL supports a native JSON type. JSON values are not stored as strings, instead using an internal binary format that permits quick read access to document elements. JSON documents stored inJSON columns are automatically validated whenever they are inserted or updated, with an invalid document producing an error. JSON documents are normalized on creation, and can be compared using most comparison operators such as =,<, <=, >, >=, <>, !=, and <=>; for information about supported operators as well as precedence and other rules that MySQL follows when comparing JSON values, see Comparison and Ordering of JSON Values.

MySQL 5.7.8 also introduces a number of functions for working with JSON values. These functions include those listed here:

In MySQL 5.7.9 and later, you can use column->path as shorthand for JSON_EXTRACT(column, path). This works as an alias for a column wherever a column identifier can occur in an SQL statement, including WHERE, ORDER BY, and GROUP BY clauses. This includes SELECT, UPDATE, DELETE, CREATE TABLE, and other SQL statements. The left hand side must be a JSON column identifier (and not an alias). The right hand side is a quoted JSON path expression which is evaluated against the JSON document returned as the column value.

See Section 12.16.3, “Functions That Search JSON Values”, for more information about -> and JSON_EXTRACT(). For information about JSON path support in MySQL 5.7, see Searching and Modifying JSON Values. See also Secondary Indexes and Virtual Generated Columns.

Nuff.js, a shiny new javascript framework

Why Nuff.js

This framework is an attempt at a simpler communication for web applications that use a view management or templating framework, it was built to work especially well with React.js. The idea was born after I implemented flux first with vanilla js and then using Reflux. However the communication remained obscure and overcomplicated in my opinion for anyone joining a complex flux project.

 

Why the Model View Presenter pattern ?

When first working on this project I researched coding patterns that would fit what I had in mind and MVP was something that seemed to look like what I wished to accomplish. Nuff.js is thus a loose interpretation of the MVP pattern. The fact that React views only need data objects as presentation logic makes for very simple presenters. In this sense, binding presenter methods to views allows to completely decouple views from the rest of the application. The idea being that presenters are associated to models and collections, they organize data structures into the way they need to be presented for the view. The fact that React.js relies on a simple setState method to update its views allows us to easily rerender elements after change since the preseneter is made to have a reference of the view. This avoids needless pubsub communication. The view binds events, the presenter queries models and sets the views’ states accordingly.
