[Wikidata-l] running your own instance of Wikibase (for science!)
by Lydia Pintscher 29 Jan '13

29 Jan '13

Heya folks :) I've heard a lot of interest from people in running their own instance of Wikibase (the software behind Wikidata) for scientific projects. I have however not seen any more concrete plans yet. I'd love to hear about them if they exist either on or off-list.

[Wikidata-l] Database used by wikidata
by Hor Meng Yoong 29 Jan '13

29 Jan '13

Dear All: What is the preferred database to be used by wikidata? I understand that MySQL is the default database for wikimedia but it is now slowly shifted to MariaDB. What about PostgreSQL? Best regards HM

Right. While I agree that PG is a great DB system, it's not what MediaWiki or Wikibase are primarily developed on and for. In theory, MediaWiki has full PG support, and we aim to also have that in Wikibase. But in practice, PG support is frequently broken especially in alpha and beta versions (and remember: what we run live on Wikipedia & Co is the alpha version; and for Wikibase, the alpha version is the only version so far). So PG is probably not the best choice for your Wikibase install. -- daniel -- Daniel Kinzler, Softwarearchitekt Wikimedia Deutschland - Gesellschaft zur Förderung Freien Wissens e. V.

[Wikidata-l] [Wikimedia Announcements] Wikimedia sites to move to primary data center in Ashburn, Virginia. Disruption expected.
by Guillaume Paumier 20 Jan '13

20 Jan '13

[Apologies for cross-posting; this concerns all Wikimedia projects] Posted today on the Wikimedia Tech Blog: https://blog.wikimedia.org/2013/01/19/wikimedia-sites-move-to-primary-data-… Wikimedia sites to move to primary data center in Ashburn, Virginia Next week, the Wikimedia Foundation will transition its main technical operations to a new data center in Ashburn, Virginia, USA. This is intended to improve the technical performance and reliability of all Wikimedia sites, including Wikipedia. Engineering teams have been preparing for the migration to minimize inconvenience to our users, but major service disruption is still expected during the transition. Our sites will be in read-only mode for some time, and may be intermittently inaccessible. Users are advised to be patient during those interruptions, and share information<https://meta.wikimedia.org/wiki/Wikimedia_maintenance_notice>in case of continued outage or loss of functionality. The current target windows for the migration are January 22nd, 23rd and 24th, 2013, from 17:00 to 01:00 UTC (see other timezones<http://www.timeanddate.com/worldclock/fixedtime.html?msg=Wikimedia+data+cen…>on timeanddate.com). Wikimedia sites have been hosted in our main data center in Tampa, Florida, since 2004; before that, the couple of servers powering Wikipedia were in San Diego, California. Ashburn is the third and newest primary data center to host Wikimedia sites. A major reason for choosing Tampa, Florida as the location of the primary data center in 2004 was its proximity to founder Jimmy Wales’ home, at a time when he was much more involved in the technical operations of the site. In 2009, the Wikimedia Foundation’s Technical Operations team started to look<https://blog.wikimedia.org/2009/04/07/wmf-needs-additional-datacenter-space/>for other locations with better network connectivity and more clement weather. Located in the Washington, D.C. metropolitan area, Ashburn offers faster and more reliable connectivity than Tampa, and usually fewer hurricanes. The Operations team started to plan and prepare for the Virginia data center in Summer 2010. The actual build-out and racking of servers at the colocation facility started in February 2011, and was followed by a long period of hardware, system and software configuration. Traffic started to be served to users from the Ashburn data center in November 2011, in the form of CSS and JavaScript assets (served from “bits.wikimedia.org“). We reached a major milestone in February 2012, when caching servers were set up to handle read-only requests for Wikipedia and Wikimedia content, which represent most of the traffic to Wikipedia and its sister sites. In April 2012, the Ashburn data center also started to serve media files (from “upload.wikimedia.org“). Cacheable requests represent about 90 percent of our traffic, leaving 10 percent that requires interaction with our web (Apache) and database (MySQL) servers, which are still being hosted in Tampa. Until now, every edit made to a Wikipedia page has been handled by the servers in Tampa. This dependency on our Tampa data center was responsible for the site outage in August 2012<https://blog.wikimedia.org/2012/08/06/wikimedia-site-outage-6-august-2012/>, when a fiber cut severed the connection between our two locations. Starting next week, the new servers in Ashburn will take on that role as well, and all our sites will be able to function fully without relying on the servers in Florida. The legacy data center in Tampa will continue to be maintained, and will serve as a secondary “hot failover” data center: servers will be in standby mode to take over, should the primary site experiences an outage. Server configuration and data will be synchronized between the two locations to ensure a transition as smooth as possible in case of technical difficulties in Ashburn. Besides just installing newer hardware, setting up the data center in Ashburn has also been an opportunity for architecture overhauls, like incremental improvements of the text storage system<https://blog.wikimedia.org/2011/11/18/nobody-notices-when-its-not-broken-ne…>, and the move to an entirely new media storage system<https://blog.wikimedia.org/2012/02/09/scaling-media-storage-at-wikimedia-wi…>to keep up with the growth of the content generated and curated by our contributors. Wikimedia’s technical infrastructure aims to be as open and collaborative as the sites it powers. Most of the configuration of our servers<https://blog.wikimedia.org/2011/09/19/ever-wondered-how-the-wikimedia-serve…>is publicly accessible, and the Wikimedia Labs <https://blog.wikimedia.org/2012/04/16/introduction-to-wikimedia-labs/>initiative allows contributors to test and submit improvements to the sites’ configuration files. The Wikimedia Foundation currently operates a total of about 885 servers, and serves about 20 billion page views a month, on a non-profit budget that relies almost entirely on donations from readers. -- Guillaume Paumier

[Wikidata-l] Double Entries
by Lukas Benedix 19 Jan '13

19 Jan '13

Hi, the handling of double Entries is strange. The warning, that you created an allready existing Item comes up very late. What I did: * Search for "Käsebrot" -> not found * Create a new Item o enter Label: "Käsebrot" o enter Description: "ein Brot mit einem Belag aus Käse" * Add "Also known as": "Käsestulle" * try to add a Link to de:Käsebrot o get the following Error-Message: "An error occurred while trying to perform save and because of this, your changes could not be completed." o click Details: Edit not allowed: Site link [[dewiki:Käsebrot]] already used by item [[Q1795455]]. That is quite frustrating... It took seven steps until I get informed about the Error I made. I figured out, that you only check for double Entries when you enter a Label and a Description in the currently selected language in the second Step. That check is also a check for bitwise equality. One different character in the description and you get no warning. If the desctiption and Label equals to an existing item you get the following Error-Message: "Another item (3220891) already has label "Käsebrot" and description "ein Brot mit einem Belag aus Käse" associated with language code en". I think you should: * enable the search for Item-Labels * check the Label when creating a new Item * add Links to the existing Item in the error-messages After my tests there are several Items with the Label "Käsebrot", I'm sorry for that.
