Hello! Capital Consulting (aka SafeGuard Switzerland) is organizing a few drinks in Geneva next Thursday (May 26). So I'll be in Geneva for the evening. I'll make sure I attend our standup, but will take a couple of hours off in the CEST evening. Exact time to be confirmed... Take care, MrG -- Guillaume Lederrey Operations Engineer, Discovery Wikimedia Foundation

update: wikipedia.org portal
by Deborah Tankersley 20 May '16

20 May '16

Hello, The Discovery Team recently added descriptive text to the Wikipedia.org page footer in order to give visitors a better idea of what the sister wiki projects are really all about. Check it out at www.wikipedia.org or view a mobile screen capture here <https://www.mediawiki.org/wiki/File:Descriptive-text_sister_projects-wikipe…> . We also wrapped up a quick, one question survey that ran for a week on the portal to determine how visitors arrive at the page. The results showed that many of the visitors arrive by clicking on a bookmarked link or by typing in 'wikipedia' in their browser. We had many encouraging and uplifting comments as well - see the full results here <https://commons.wikimedia.org/wiki/File:Wikipedia_Portal_Survey_-_May_2016.…> . In the coming weeks and months we'll be reaching out to many of those survey takers who graciously provided their name and email addresses to engage in deeper conversations on how they use the portal and Wikipedia in general. As always, more detailed information is available on wiki for the Wikipedia Portal <https://www.mediawiki.org/wiki/Wikipedia.org_Portal> and A/B testing <https://www.mediawiki.org/wiki/Wikipedia.org_Portal_A/B_testing>. On behalf of our happy little Wikipedia.org Portal team, Deb -- Deb Tankersley Product Manager, Discovery Wikimedia Foundation

Re: [discovery] [Analytics] University project to make entire English Wikipedia history searchable on Hadoop using Solr

Yes, of course *processing* the entire history (even with text) has been done before - but perhaps not storing or indexing it.

University project to make entire English Wikipedia history searchable on Hadoop using Solr
by Tilman Bayer 17 May '16

17 May '16

Detailed technical report on an undergraduate student project at Virginia Tech (work in progress) to import the entire English Wikipedia history dump into the university's Hadoop cluster and index it using Apache Solr, to "allow researchers and developers at Virginia Tech to benchmark configurations and big data analytics software": Steven Stulga, "English Wikipedia on Hadoop Cluster" https://vtechworks.lib.vt.edu/handle/10919/70932 (CC BY 3.0) IIRC this has rarely or never been attempted due to the large size of the dataset - 10TB uncompressed. And it looks like the author here encountered an out of memory error that he wasn't able to solve before the end of term... -- Tilman Bayer Senior Analyst Wikimedia Foundation IRC (Freenode): HaeB -- Sent from Gmail Mobile

Re: [discovery] [Wikidata] WDQS instabilities - Incident report
by Guillaume Lederrey 11 May '16

Hey! No, the issue is unrelated. We are having a few issues with Varnish upgrades. To be honest, I don't entirely understand what the issue is, so I will not even try to explain it. I expect we will have an incident report coming soon.

Elasticsearch slowdown - incident report
by Guillaume Lederrey 10 May '16

10 May '16

Hello! Yesterday around 21:43 UTC we experienced a slowdown of Elasticsearch. In short, one of our elasticsearch server went crazy with its garbage collector and had to be restarted. You can find more details in the incident report [1] or the corresponding Phabricator task [2]. Thank you all for your understanding!
