Thus, the existence of duplicates does not affect the value of the extreme order statistics. There are other estimation techniques other than min/max sketches. The first paper on count-distinct estimation [7] describes the Flajolet–Martin algorithm, a bit pattern sketch. In this case, the elements are hashed into a bit vector and the sketch ...
Power Query was first announced in 2011 under the codename "Data Explorer" as part of Azure SQL Labs. In 2013, in order to expand on the self-service business intelligence capabilities of Microsoft Excel, the project was redesigned to be packaged as an add-in Excel and was renamed "Data Explorer Preview for Excel" [4], and was made available for Excel 2010 and Excel 2013.

In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs.
Combinatorics is an area of mathematics primarily concerned with counting, both as a means and as an end to obtaining results, and certain properties of finite structures.It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science.
Duplicate images – tool to show duplicate files between Wikipedia and Commons (at the toolserver) Push-for-commons – tool to show a set of images from a wikipedia, helping to find license problems, {{ NowCommons }} candidates, and images that should be copied/moved to the commons (at the toolserver)
Since the 2013 RfC on Wikidata Phase 2, using Wikidata in infoboxes has gone from the concept stage to more extensive mainspace experimental implementations.This had led to some controversies: some editors have been converting infoboxes to use Wikidata, believing use of Wikidata brings significant benefits, while other editors have been removing Wikidata from infoboxes, believing use of ...
The idea for the general proof follows the above supplemental case: Find an algebraic integer that somehow encodes the Legendre symbols for p, then find a relationship between Legendre symbols by computing the qth power of this algebraic integer modulo q in two different ways, one using Euler's criterion the other using the binomial theorem.
I'm running this query now, which should do it: select pl_title from pagelinks inner join page as srcpage on ( pl_from = srcpage . page_id ) left outer join page as dstpage on ( pl_title = dstpage . page_title ) where srcpage . page_namespace = 0 and pl_namespace = 0 and dstpage . page_title is null group by pl_title having count ( * ) = 1 ;
