Datafari is an Open source enterprise search software using Apache Solr (the projects from the Apache Software Foundation). It is a packaged search engine in a sense that it proposes the connection to data sources, the indexing, the search and the graphical administration of the system. The software is distributed (architecture of type Distributed computing) using SolrCloud. Datafari uses Apache Solr for the index and search phases. It combines Apache ManifoldCF, Apache Solr and Apache Cassandra. based on HTML5, CSS3 and jQuery.
Background
Datafari was created by France Labs. France Labs looked for an open source search software to enhance its R&D with a new intranet relevancy algorithm. The team found that there was nothing being well maintained and available under an Apache License and created Datafari. It became independent from the research on the algorithm, considering that it had search value by itself. The first open source version was released on March 4, 2015 with version number 1.0. In May 2015, thanks to Datafari, France Labs won the Big Data trophy at the IT Innovation Forum. Version 2.0 (this major version change was due to the technical migration from Solr 4 to Solr 5) has been released on Sept. 7th 2015.
The company France Labs was created end of 2011 by Cédric Ulmer, Olivier Tavard and Aurélien Mazoyer ; its headquarters are located in Nice, France.

Notes and references
United States anti-government unrest refers to the general rise of unrest in the United States to the point where anti-government unrest has become near continual across many movements. The movements are loosely allied or at least associated with each other and are themselves usually loosely connected and decentralized.
It is generally considered to have taken stronghold in the middle 2010s intensifying so much so that it is sometimes called the United States uprising. In 2016, especially with the Malheur incident, some have suggested it is another "United States civil war", not to be confused with the earlier American Civil War.
Background
Tension had built up in the United States for quite some time. Eventually the approval ratings for the branches of federal government had reached all time lows in the single digits. This had coincided with promotion of social equality which had the opposite intended effect of growing economic inequality. The War on Terror and other effects of Globalization mitigating the strength of American exceptionalism intensified the domestic unrest.
Timeline
Listed are the most intense of the movements and other unrest chronologically by when they formed that have devolved into the overall unrest.
*Patriot movement, Redemption movement, and Militia Movement - 1990s (stable)
**Occupation of the Malheur National Wildlife Refuge - 2016 (ended)
*Occupy movement - 2011 (stable)
*Black Lives Matter - 2013 (escalating)
**Ferguson unrest - 2014 (stable/ended?)
**Baltimore protests - 2015 (deescalating/ended)
When used as an umbrella term sometimes lesser intensity examples are included. Gamergate, Tea Party movement, and Anonymous are hardly anti-government unrest, and certainly not on an "Another american civil war" level. In addition to these legitimate movements, there are insurgencies that have anti-government motives as a lesser side objective, such as Islamism.
Some predict that the ongoing Cold War II could escalate into World War III continuing to exacerbate the unrest.

Million Fishes was an incubation program in San Francisco, CA where emerging artist of visual art, filmmaking, choreography / dance, music, conceptual art, new media, interactive art, interarts, and writing could build the tools necessary to establish themselves as contributors of art. It is located at 2501 Bryant Street (at 23rd Street), San Francisco, CA. Million Fishes empowered artists by creating an environment in which they can create, critique, present, teach, and develop the concepts and skills involved in producing art and sharing it with others. Through presenting and making accessible the programs’ new emerging artwork and ongoing projects, Million Fishes became a resource to local communities in the Mission District and the diverse, extended communities of our resident artists. Million Fishes began its operations in November 2003 and ended operations in October 2012.
Organization History
Founded in 2003 on the principle of co-creativity, the studios and venue served as a platform for artistic cooperation as well as an interactive resource for the public. Million Fishes grew to also suit the needs of many distinct creative endeavors, from productions and events to ongoing programs and services. Through presenting and making accessible emerging artwork from both the collective and outside artists, Million Fishes was a resource to local communities in the Mission District and the extended communities of our resident artists. Programs include innovative gallery exhibitions, an artists-in-residence program for 14 artists from international backgrounds, and classes and workshops open to the community.
The collective also featured valuable resources including a dark room, wood shop, and studios for all disciplines.
Strengths included a positive impact and presence throughout the local community, and the quality of the events and programming.

The electrical system of the Kolkata class destroyer warships consists of total 14 EDCs (Energy/Electrical Distribution Centre) - 7 in FWD section and the other 7 in AFT section of the ship. There are total 4 feeder circuits - 2 in FWD section and the other 2 in AFT section.
There are total 5 alternators - 4 gas turbine AC generators (GTG) / Alternators (Wartsila WCM 1000) namely J1, J3, M2, M4 and 1 diesel alternator K manufactured by Kirloskar Electricals.
Each of them have 3 phase output voltage in the range 380-400 V, output current of 2500 Amp and power output of 1 MW.
Their operation temperature is maintained as - Operating Temperature <= 500 degree Celsius.
Normally, the GTG J1 and J3 are used in the FWD section whereas M2 and M4 are used in the AFT section of the ship.
The diesel alternator K is common to both the sections of the ship.
The EDCs are the interface circuitry between the alternators and the bus circuitry.
The feeder circuitry functions as an interface between the bus circuitry and the ship’s on-board electrical equipment.
The power generated by the alternators energizes the bus circuitry.
More than one alternator can be used to energize the bus by combining them and putting their output in parallel connection.
The combination or separation of the alternators is controlled through the EDCs.
The alternator outputs are connected or disconnected from the bus through their individual EDCs for e.g. EDC 1, 2, 13, 14.
The EDCs generally consist of heavy duty circuit breakers and relays. The EDCs can be operated manually or in semi-automatic mode. The automatic operation can be executed through electronic controller units (ECU).The semi-automatic and fully automatic mode of operations require some amount of manual monitoring at regular time intervals.
The feeder network consists of circuit breakers, current limiting, over voltage protection and voltage regulating circuitry.
The alternators in the FWD section can also be used to energize the AFT section of the ship and vice-versa.
The diesel alternator K is used in the case of emergency situation or when the ship is on shore as an alternate mode of electrical power supply. While sailing ashore, the GTGs are used.
When the ship is docked on shore, the shore supply is coupled to the EDCs instead of the alternator power output through Shore Control Box (SCB).
