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.
Cheers
Lydia

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.

Hello!
Today, I will switch our demo repo and client to new Labs instances
which are managed by puppet. In the first step, these installations will
not have all the extensions we normally have on the demo instances.
Also: If you have permission problems when editing please tell me.
Best,
Silke

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.

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.
