Bad Merge[edit]

Hi. Mea culpa. I was tidying up Vincetoxicum hirsutum (Q124757631) when I noticed a duplicate Q15380282 with a technically correct, but too long, title. I attempted to merge them, but I ended up with the long undesirable title. I cannot now undo the merge. Can someone please replace the title with just the binomial? Thanks Big Blue Cray(fish) Twins (talk) 22:31, 2 April 2024 (UTC)[reply]

@Big Blue Cray(fish) Twins: I think the merge should just be undone since someone intentionally indicated they are different. --Matěj Suchánek (talk) 08:51, 6 April 2024 (UTC)[reply]

WDQS wikibase:around issue[edit]

The wikibase:around service seems to be exhibiting a failure illustrated by the following two queries. The first query looks for items centered on the coordinate of Hack Green Secret Nuclear Bunker (Q5637175). It should return Hack Green Secret Nuclear Bunker (Q5637175) as one of the items found, but does not. The second query looks for items centered on the coordinate of Hack House Farmhouse (Q62130029), which was the single result in the first query. It finds itself, and it also finds Hack Green Secret Nuclear Bunker (Q5637175). This second query demonstrates that wikibase:around should return items having centre-point coordinates, and also demonstrates that Hack Green Secret Nuclear Bunker (Q5637175) data is in the triplestore and accessible to a wikibase:around query; and so the issue is that Hack Green Secret Nuclear Bunker (Q5637175) is not being returned by the first query. Why does the first query not return Hack Green Secret Nuclear Bunker (Q5637175)?

SELECT DISTINCT ?item ?itemLabel WHERE 
{
  wd:Q5637175 wdt:P625 ?targetLoc. # hack green bunker
  SERVICE wikibase:around {
    ?item wdt:P625 ?location.
    bd:serviceParam wikibase:center ?targetLoc.
    bd:serviceParam wikibase:radius "0.3".
    bd:serviceParam wikibase:distance ?dist.
 }
 SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
}

Try it!

SELECT DISTINCT ?item ?itemLabel WHERE 
{
  wd:Q62130029 wdt:P625 ?targetLoc. # hack green bunker
  SERVICE wikibase:around {
    ?item wdt:P625 ?location.
    bd:serviceParam wikibase:center ?targetLoc.
    bd:serviceParam wikibase:radius "0.3".
    bd:serviceParam wikibase:distance ?dist.
 }
 SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
}

Try it!

We can get a clearer response from the Search team. Let's move this conversation here. -Mohammed Abdulai (WMDE) (talk) 11:09, 8 April 2024 (UTC)[reply]

Unexpected increase in byte size[edit]

Not exactly a technical problem, I guess... I was just curious, why do some minor edits make the item increase so much in byte size? As an example, this minor edit caused the item to increase 2130 bytes in size. Would love to understand the logic behind this. —capmo (talk) 04:31, 10 April 2024 (UTC)[reply]

@Capmo: See Help:FAQ#Editing #13; it mostly happens when editing very old revisions (in the case you linked, the last edit was almost ten years ago). Lucas Werkmeister (WMDE) (talk) 08:15, 10 April 2024 (UTC)[reply]

Danke schön, Herr Werkmeister! Things are much clearer now. Knowing that data is stored in json format explains a lot. Regards, —capmo (talk) 15:07, 10 April 2024 (UTC)[reply]

Español Latinoamericano es-419[edit]

Al seleccionar un idioma en Wikidata aparece entre otras opciones "español latinoamericano es-419". Esta denominación es incorrecta, ya que la palabra "latinoamericano", no solo se refiere al idioma español, sino también al portugués, al francés, al italiano, al rumano, etc. Para referirse correctamente al español que se habla en América, la expresión debería aparecer de la siguiente forma: "español hispanoamericano es-419". Un cordial saludo: Raimundo Pastor (talk) 19:08, 14 April 2024 (UTC)[reply]

Hola, una de las acepciones del adjetivo hispanoamericano es "Perteneciente o relativo a españoles y americanos."[1] y por lo tanto no puede ser utilizado para definir el idioma hablado en Latinoamerica. Saludos —capmo (talk) 20:54, 14 April 2024 (UTC)[reply]

Possible problems from exceeding 2^31 edits[edit]

We are getting really close to this limit. I looked around in archives and on Phabricator and even if the main database can handle it, there might be third party tools that need patching within the next few weeks when this is reached. Something to monitor closely. 77.103.193.166 07:32, 17 April 2024 (UTC)[reply]

For the record, the main task about this is T63111, and we’re tracking relevant values on Wikidata in particular on Grafana; you can see there that the recentchanges, cu_changes (cu = CheckUser) and text tables all crossed 50% already, and I didn’t hear reports of breakage about those. Lucas Werkmeister (WMDE) (talk) 09:10, 17 April 2024 (UTC)[reply]

(Minor correction: in fact the cu_changes.cuc_id is currently being made 64-bit, see T355609. That’s why its line in the Grafana dashboard cuts off ~2 weeks ago.) Lucas Werkmeister (WMDE) (talk) 10:34, 17 April 2024 (UTC)[reply]

Property:P2671[edit]

Please remove the effects of the vandalism. I cleared the cache on the item, but no result. — Tarkoff / 15:03, 18 April 2024 (UTC)[reply]
