OK I understand but. The column name was not in the kindly provided data dictionary and read "IdPrel". I thought "preliminary ID"? Turns out the data is from Quebec and it was actually ID prélèvement - sample ID... Seems obvious in hindsight. Also, vcode was not visit code but code volet. *sigh*

ojej. A ja w zeszłym roku odwiedziłem i wreszcie zobaczyłem salę, w której podpisano pokój westfalski - przez sześć lat mieszkania w MS mi się nie udało...

Hey #birders and #bird lovers from EU! Half of the new Euro banknotes designs are with birds :-D and you can vote on your favorite: ecb.europa.eu (the screenshots are from different designs, that's why they don't match)

For todays #BirdOfTheDay theme, #Corvidae, I have this hooded crow - I watched it play with a bit of plastic for I think a quarter of an hour or so. It was definitely a playful behavior, it kept throwing and catching the clean plastic. #Birds

Nie używam apki. Poza tym to może ewentualnie działać dla feedów algorytmicznych, prawdopodobnie działa dla "Discovery", ale prawie na pewno nie dla third party jak "For You" i z całą pewnością nie dla "Following". A "Discovery" nie używam.

Todays #BirdOfTheDay theme is #SingersAndWingers. Here is a common nightingale (słowik rdzawy, Luscinia megarhynchos), which intruded upon our sleep in May (the photo is shot like five meters from our bedroom window...) #birds

aparently that is so. I just tried the same trick with one of your photos (the motorcycle at sunset), and I did not get any useful EXIF info:

I think I am misunderstanding something. I can see that the PDS does contain my original EXIF info. What I downloaded directly from my PDS (which was uploaded by zeens) did contain all exif info:

For the #BirdOfTheDay secondary theme - #MomentsOfMajesty, hear me out: little birds like this goldfinch (szczygieł, Carduelis carduelis) can be majestic and proud, too! ...ok, maybe not so much. #birds

For #MacroMonday - a Tachina fly (no idea which species). The larvae of these flies are parasitoids which feed on various butterfly or moth larvae; but the adults feed on nectar and pollen. Like very ugly butterflies :)

Todays #BirdOfTheDay theme is #ButtShots - well, this is maybe not exactly a butt shot, but it is definitely the rear, and I like this photo very much (EXIF info on zeens.app). Great tit, bogatka (Parus major).

In Polen kann man in Lidl diesen veganen "Schinken" kaufen, und das ist mit Abstand der beste vegane Aufschnitt den ich je probiert habe. Immer wenn wir in Polen sind, kaufen wir einen Haufen davon.

I tried it on some of my packages, so far it did not find any problems but I do check() on a regular basis. But it compiles w/o issues and is super fast, much faster than check(), so I will keep using it. It had some false positives, though, e.g. the tags package defines a list tags.

What a lovely rant :-D
Some of these comments, like the proscription on the use of ANOVA with small samples, the suggestion to use power analysis to determine if sample size was large enough to do a parametric test, or the concern that a significant result still might be a Type II error, are simply wrong and reveal more about the reviewer’s competence than the study design.Parametric statistics can be used with Likert data, with small sample sizes, with unequal variances, and with non-normal distributions, with no fear of “coming to the wrong conclusion”. These findings are consistent with empirical literature dating back nearly 80 years. The controversy can cease (but likely won’t)

OK, so this is not a good photograph, but the #BirdOfTheDay theme is #Lifer - the last new bird I photographed. And this is common linnet, makolągwa, which I photographed for the first time in my life this February. But they were so far high up in the tree that this is the best I could do. #birds

Uwielbiam polskie nazwy. Jak można nazwać ptaszka, który ma ogon długi jak sroka i w dodatku czarno-biały, a na kuprze białe piórka? Sroczek białorzytny, oczywiście. Kittacincla malabarica, white-rumped shama. Obciąłem mu ogon, niestety. Obiecuję, że to na dziś ostatni ptaszek z ZOO.

tak. I dlatego używam zeens.app. Jak wejdziesz na zeens.app (loguj się normalnie przez ATProto) to tam zobaczysz ten obrazek z prawidłowym exifem. (nie do końca, ale to nie wina zeens, tylko rawtherapee - która dawniej nie zachowywała informacji o obiektywie)

These flowers at the Warsaw Zoo were teeming with life #MacroMonday #insects. The black and red beetle may be a Trichodes (apiarius? - Barciel pszczołowiec). The one on the right looks like Oxythyrea funesta (Łanocha pobrzęcz). But I don't know them well, just looked at a bunch of pictures :)

I love the todays #WildMotion #BirdOfTheDay theme. Some of these photos are absolutely wild. mu.social/profile/bobp... (also, this is a test checking whether and how zeens handles reposts). #birds (yeah, these are black headed gulls fighting over a morsel of bread)

Today's alternative #BirdOfTheDay theme is #peekaboo, so I just have to share this sparrow (wróbel domowy, P. domesticus) from outside of my kitchen window. We only get house sparrows here; in my parent's garden otoh there are only tree sparrows (mazurek, P. montanus) #birds (zeens.app as always).

Genau so ist es.
Springer gegen die Brandmauer

Während das angebliche Treffen jetzt rauf und runter diskutiert wird, ist das nicht einmal die wichtigste Frage. Sowohl die Krise zwischen Merz und Springer als auch die Liebäugelei des Konzerns mit der AfD sind längst offensichtlich. So offenbart ein Blick in die publizistischen Springer-Erzeugnisse, dass Bild und Welt öffentlich und unverblümt eine Zusammenarbeit mit der AfD herbeischreiben. Der Journalist Sebastian Friedrich lieferte im Blog „Über Rechts“ eine Sammlung von Beiträgen, die in den letzten Monaten erschienen sind.
