Lucas Werkmeistergood morning
current status: traveling towards other nerds at velocities in excess of 250 km/h
btw, earlier there was an announcement that a group of chess players is on the train (one of whom was speaking, evidently), either on the way to or from some tournament (I forget the details), and anyone is welcome to come visit carriage 7 for a match :D
(I feel like this has happened before – it might well be an annual tournament, and I would've taken basically the same train on the same day up north in some previous years. but apparently I didn't post about it last time)
okay, I think they must be en route to this tournament: https://www.deutsche-schachjugend.de/termine/2025/dvm-u20w/ (i.e., youth championships for female participants up to 20 years old)
the date matches, the location matches the direction of this train (northwards), and it matches what I seem to remember from the announcement ^^

good night #39c3 
good morning #39c3!
I didn’t even have time to announce my talks on here 😭 I only got the slides ready+translated+uploaded at the last minute 😅
but anyway!
hier sind die Folien für meine Wikidata-Einführung, die um 14:45 im Free Knowledge Habitat statfand: https://commons.wikimedia.org/wiki/File:Free_Knowledge_Habitat_39c3_(2025)_-_Wikidata_Introduction_DE.pdf
here are the slides for the Wikidata introduction I did at 3:15pm in the Free Knowledge Habitat: https://commons.wikimedia.org/wiki/File:Free_Knowledge_Habitat_39c3_(2025)_-_Wikidata_Introduction_EN.pdf
if you want to know more about Wikidata, Andrew McAllister and I are doing an Intro to SPARQL and Wikidata Query Service at 8:30pm today, also in the Free Knowledge Habitat: https://pretalx.wikimedia.de/39c3-2025/talk/RNWUH8/
Intro to SPARQL and Wikidata Query Service (EN) Free Knowledge Habitat 39c3
The WIkidata Query Service (WDQS) is one of the main services to get data from Wikidata. In this workshop we'll explore the SPARQL query language that allows us to access data as well as the WDQS UI, a helpful UI in which we can write and run queries. The goal is that you'll be able to write your own queries and explore Wikidata's data by the end of the session.
I have a DECT now btw, LUWE (5893) ^^
time from tooting my DECT number to receiving a call: approx. ten seconds
good night #39c3 
good morning #39c3!
I should try to get a bit more sleep tonight tho
Stolperfallen--;

I have the nail polish with me btw, if anyone else would like to have their nails painted 
heute Abend (20:00–21:00) im Free Knowledge Habitat: Wikidata Live Querying! wir denken uns gemeinsam interessante SPARQL-Anfragen für Wikidata aus ^^ (kommt zahlreich weil alleine werd ich nicht so viele Ideen haben 
) https://pretalx.wikimedia.de/39c3-2025/talk/VTELBK/
(I don't quite remember if doing this (only) in German was an intentional decision back whenever I added this to the CfP… would a lot of people be interested in an English version of Wikidata Live Querying at some later time, if we find space in the schedule? ^^)
I think the live querying workshop went fairly well
and I also ended up allocating the https://w.wiki/HELP short URL during it 😭 we probably could’ve used that for something more useful. oh well lol
RE: https://blahaj.social/@DorkusShorkus/115799146316120498
if @DorkusShorkus was taller or more athletic, I wouldn’t have had to crane my back+neck down so much in order to talk into the microphone while typing 😤
some queries from the live querying session:
• Swahili verb lexemes, with English sense glosses if available: https://w.wiki/HEKo
• translations of a certain word based on lexemes: https://w.wiki/HEKx
• statements of the Swahili item: https://w.wiki/HELP
mindestens einen Nobelpreis für die Person die sich das Akronym „Mehrere Orte im Norden“ ausgedacht hat btw
good night #39c3

good morning #39c3! (I set my alarm half an hour later than yesterday, hopefully that helps a bit ^^)
who up geheiming they orga
good morning #39c3! (ec selfie, bit more intense eye contact than usual I think)
I forgot to announce my session in advance again 😅 but enough people were still interested in the WDQS introduction in German!
some of our queries:
• items founded by Jimmy Wales or Larry Sanger (I don’t endorse etc. etc.): https://w.wiki/HEe3
• events in series organized by CCCV: https://w.wiki/HEeS
• CCC-affiliated events (more complicated version of the above): https://w.wiki/HEfA
• how many other item-type statements the #39c3 item has: https://w.wiki/HEex
• awards received by Albert Einstein: https://w.wiki/HEfL
• ancestors of Louis XIV: https://w.wiki/HEg8

WP:Persönliche Bekanntschaften aber für plushies #WasFehlt
I'm way too late with this post, but: please feel free to take photos of me at #39c3 (as long as everyone else in them agrees ofc). I'd love to have some! (I trust you won't publish something very unflattering like when I'm in the middle of eating a hot dog ^^)
this is a confirmation that an item ID, combined with the term “Qid” (according to the courier), is enough for delivery :3
by popular demand*, I’m doing another Wikidata introduction tomorrow! 10:45 AM, at the Free Knowledge Habitat: https://pretalx.wikimedia.de/39c3-2025/talk/YLBHLH/
* nobody explicitly asked for it, but the Wikidata introductions on day 1 were quite well attended (both the German and English edition), so I hope enough people will be interested, around this early in the morning, and see this announcement (or the schedule entry) in time 😅
good night #39c3 😌
RE: https://wikis.world/@LucasWerkmeister/115805355771091840
there was in fact demand for another Wikidata introduction, our workshop area was pretty full again \o/
up next (in 2 minutes ^^) in the Free Knowledge Habitat (next to the escalators on the first floor, opposite hall X): A whirlwind tour through the land of Wikidata-powered apps! https://events.ccc.de/congress/2025/hub/en/event/detail/a-whirlwind-tour-through-the-land-of-wikidata-powe
[39c3] A whirlwind tour through the land of Wikidata-powered apps
Wikidata's data is used in thousands of projects and often we don't realize what our work makes possible. In this session we will take a tour through some of the great applications and services that have been built on top of Wikidata's data. Join ...
TIL: available angel kitchen vouchers per meal are apparently limited, I can't generate a lunch voucher anymore despite having enough hours

Engelwasser Prickelwein, das ist billig und schmeckt fein
jk@LucasWerkmeister top habitat - sehr gerne wieder! :)
nyanbinary@LucasWerkmeister they dont want you to know but you can just pick up the knowledge & take it home
Jonas 3j14@LucasWerkmeister what is a qid? Or what do you mean by item ID?
@nichtjonas it's the identifier of an entry in https://en.wikipedia.org/wiki/Wikidata?wprov=sfla1
Semi
taavi is typing...@LucasWerkmeister @theresnotime @korenchkin I'd be up, there is a meetup I want to attend in ~25' so maybe after that?
@LucasWerkmeister will do :3
Max@taavi @LucasWerkmeister @theresnotime my next shift is at 1600, so either before that, or after 1800
