happy coming out day! here's what the famous mauritshuis museum (with vermeer's girl with a pearl earring) in the hague looked like last night during the museumnacht festival 🏳️‍🌈 #NationalComingOutDay

leuk gerelateerd weetje: de nederlandstalige en franstalige naam van de belgische stad rijsel / lille zien er nogal verschillend uit en lijken daardoor ongerelateerd, maar in beide talen is de naam een verbastering van ‘op/bij het eiland’
De stad is gesticht onder de Latijnse naam Ad Insulam, die letterlijk ‘op/bij het eiland’ betekent. Dit werd in het Middelfrans vertaald als à l’isle en in het Middelnederlands, met gebruik van het Romaanse leenwoord, als ter ijs(s)el (uitspraak [tər i:səl]). In beide talen trad verkeerde woordscheiding op. Dat gaf in Nieuwfrans à Lille en in Nieuwnederlands te Rijsel (met de klankwettige ontwikkeling van Middelnederlands [i:] tot Nieuwnederlands [ɛɪ]; de uitspraak in het Frans-Vlaams heeft nog steeds een [i]-klank, Rysel). Beide namen zijn ongeveer even oud.

love / hate relationship here 😬 (browsers, actually)
  /* As of the time of writing (2025-11), Chrome 142 (stable channel)
     and Chrome 144 (dev channel) on Android in landscape mode
     incorrectly report a nonzero ‘safe-area-inset-left’ or
     ‘safe-area-inset-right’ (at the side of the camera notch) when
     ‘viewport-fit=cover’ is used on the page, even though the area
     around the camera is not used by the web view at all (except in
     full screen mode).

     fixme: this hack breaks when using ‘zoom out’ (non standard
     option, not the same as pinch zoom) in Chrome on Android, because
     the media queries use viewport sizes which resize along with the
     zoom level, not device sizes. Detecting physical sizes is
     possible (see e.g. https://whatismyviewport.com/) but may require
     JavaScript (window.screen.height and .width).

heh, someone made a nice remark about… me appearing in that video! 🙃 💞 snarky puppy (@realsnarkypuppy.bsky.social) videos are the exception to the rule about never reading youtube comments
youtube comment:

0:15 I love this guy taking off his headphones so he can listen to all those strings he's surrounded by, unmediated.

my reply:

heh, thanks! that guy is me (not kidding). 😎

and yes, it's really nice to be surrounded by the acoustic instruments (horns & strings), but as someone else also wrote: the headphones 🎧 are really needed because without them you can't hear most of the musicians, both b/c of electronic instruments (no monitor speakers in the room!) and the sheer distance (musicians spread out over the whole floor to maximise microphone isolation).

tegen geweld? in 2007 wilde-ie schieten op de knieschijven van relschoppers www.volkskrant.nl/nieuws-achte...
Wilders: schieten op
relschoppers
DEN HAAG PVW-leider Geert Wilders wil dat de politie rellen de kop indrukt, desnoods door met scherp te schieten op raddraaiers...
30 mei 2007, 00:00
Zou de politie bij ordeverstoringen zoals in Tilburg met scherp schieten op relschoppers, dan zou daar een preventieve werking van uitgaan. 'Dat gaat vanzelf als de politie twee keer een knieschijfheeft geraakt', verwacht de PVV-leider.De agenten moeten in Wilders' Voorstel altijd eerst een waarschuwingsschot lossen en vervolgens gericht op de benen mikken van relschoppers. En de korpsleiding of de minister van Binnenlandse Zaken dient VOoraf groen licht te geven voor het neerschieten van relschoppers.Op zijn weblog schrijft Wilders dat Marokkaans-Nederlandse relschoppers moeten worden aangepakt zoals de politie en de justitie van Marokko dat zouden doen: keihard.
