Puppetized Discovery Dashboards and Shiny Server module for Puppet
by Mikhail Popov 21 Aug '17

21 Aug '17

Howdy, Happy to report that production[1] and development[2] sets of Discovery Dashboards are up and running again, this time managed by Puppet. (There was a bug with web proxies and DNS settings that delayed this announcement.) Theoretically they should be snappier to use now because there is no longer an extra virtualization (Vagrant) layer and they are running directly on Labs instances. R is a software and programming language mainly used for statistical inference, machine learning, and data wrangling & visualization. RStudio's Shiny[3] is a framework for developing web applications in R, and it's what Discovery's dashboards are written in. The Reading::Discovery::Analysis team (with guidance and help from Guillaume Lederrey) is proud to announce a new module available in Ops' Puppet repo: shiny_server[4], which installs & configures RStudio's Shiny Server[5] for serving R/Shiny applications. The module also provides resources for installing R packages from CRAN, GitHub, and other remote git repositories like Gerrit. For a practical example, refer to Discovery Dashboards base[6] and production[7] profiles.

Greetings, This is the weekly update for Discovery. As always, feedback and questions are welcome. == Discussions == === Search === * Erik's bugfixes: T171009 (don't issue a near match query with empty query), T171155 (match redirects with the ''intitle'' keyword). [0] [1] * Stas' Wikidata entity search with Elastic is in testing [2] [3] * Stas' work on the archive search is in final call, to be enabled next week. [4] * David worked on collecting features from the sltr query by using a custom Accumulator to collect feature names and extracting feature vectors from the ltr plugin [5] * Trey's language analysis analysis tools will soon be released in RelForge. See phab ticket T171516. [6] Comments on the extensive/excessive documentation copied to MediaWiki are welcome. [7] === Analysis === * Chelsy found a bug in the ''renderMenu'' function in ''shinydashboard'' package that was fixed—but we need to wait for latest version to be uploaded to CRAN before we can patch our instance [8] === Interactive === * Mapframe was enabled for cswiki by a volunteer contributor.

Discovery Weekly Update for the week starting 2017-07-17
by Chris Koerner 21 Jul '17

21 Jul '17

Hey all, This is the Discovery weekly update for the week of 2017-07-17 _including_ updates from the week of 2017-07-10 because I'm a dummy and forgot to send the update email last week! Feedback and questions are welcome. ==Highlights== * Quarterly Review check-in's were presented this week (links forthcoming). ==Discussions== * Had a good conversation on how we want to do an upcoming A/B test to have search results interleaved [0] * Also had a really interesting conversation on how we should move forward with metrics and KPIs for the Search Platform and Discovery. === Search === * After extensive help and feedback from the Japanese Wikipedia community, we decided ''not'' to deploy the new Japanese language analyzer. [1] * After testing and analysis, we are ''not'' going to deploy the Vietnamese language analyzer [2] * Did some quick analysis of the RelForge impact of initial learning-to-rank model [3] * Completed a high level task of organizing necessary adjustments to the ElasticsSearch learning-to-rank plugin [4] * Updated the Wikidata code to take advantage of nested fields noop script [5] * Analyzing the new Kuromoji Japanese language analyzer is done, just waiting to merge the updated configuration [6] * A/B test for the new search results Explore Similar feature continues after fixing a minor bug [7] [8] * Fixed a mapping bug when using text for 'did you mean' suggestions [9] * Updated the 'cirrussearch-explore-similar-languages-none' message to be more meaningful (will be deployed the week of July 25, 2017) [10] === Analysis === * To track sister project search feature, the Search Metrics dashboard now shows traffic to various Wikimedia projects from Wikipedia search results pages [11] [12] * We found what lowered full-text search PaulScores – it was a change of event logging sampling rates (decreasing enwiki and increasing all other wikis). [13] [14] * Investigated the seemingly odd statistic of mobile web having the highest usage of the sister project snippets in the search results page; conclusion: nothing to worry about, everything is being logged correctly. [15] === Portal === * The Wikipedia portal stats and translations were updated on July 18, 2017 [16] [17] === Maps === * A usage policy was recently changed for the relief data layer that we use in maps to now require an API key; a key was procured and Max S helped us get it into production. This only effected maps on Wikivoyage.

Thanks to Erica Litrenta for sharing this with me. I thought I'd share if forward.
