Hi there, since 1996 I have been working on (online) projects in telecom, broadcast media and the public sector. I like to learn new things, and have a passion for photography, plants and music.

Two Sketches of Figures on the Dunes near Scheveningen, Jan de Bisschop, 1660
De Bisschop covered Charles II’s departure to England like a news reporter. He recorded the momentous event in swiftly executed sketches in black chalk, which he later worked up in pen and brush. These sketches served as the foundation for the large finished drawing also on view here (adjacent).

de ruige rudbeckia (Rudbeckia hirta) doet z'n naam eer aan want is flink behaard.

Foto van een uitlopende knop van een Zonnehoed, ruige rudbeckia (Rudbeckia hirta); een oranjegele bloem met een bruine knop, een harige steel en bloemblaadjes.

Uit Wikipedia:

De ruige rudbeckia bloeit vanaf juli tot in oktober. De bloeiwijze is een 4-8 cm groot hoofdje met 8-16 met meestal uniform gele tot geeloranje, elliptische, min of meer naar beneden gerichte lintbloemen (of met een kastanjebruine vlek) en 250 tot meer dan 500 zwartbruine buisbloemen. De 15-45 mm lange en 5-10 mm brede lintbloemen zijn aan de onderkant bezet met korte haren. De buisbloemen hebben aan de voet een puntige, lineair-lancetvormige stroschub, die ongeveer even lang is als de buisbloem. De 12–22 × 10–20 mm grote bodem van het hoofdje is halfbolvormig tot conisch. De in twee tot drie rijen gerangschikte, 10-15 mm lange en 2-3 mm brede omwindselbladen zijn afstaand of naar achteren gebogen en ruw behaard.

De vrucht is een 1,5-2,7 mm lang nootje.

Starflower/Borage (Borago officinalis)

Borage just about to set full flowers against the backdrop of a street with a dedicated path for bicycles.

(Borage in Wikipedia)

Borage is used as either a fresh vegetable or a dried herb. As a fresh vegetable, borage, with a cucumber-like taste, is often used in salads or as a garnish.

The flower has a sweet, honey-like taste and is often used to decorate desserts and cocktails, sometimes frozen in ice cubes.

de bladeren van het plantje zien eruit als die van een sinaasappel of citroen, een heptacodium heeft een andere nerf en de groeiwijze is anders.

nouja, weer wat geleerd.

What a hot mess.

Climate change dashboard updated through last month: zacklabe.com/climate-change-in

This graphic shows four line graph time series and each are monthly from January 1984 through May 2025. The first graph is a 12-month running mean of global mean surface temperature anomalies. Anomalies are computed relative to a 1991-2020 baseline using ERA5 data. The second graph is monthly carbon dioxide abundance. The CO2 graph is the Keeling Curve. Current levels are 431 ppm. The third graph is monthly global methane abundance. Current levels are 1934 ppb. The fourth graph is monthly global nitrous oxide abundance. Current levels are 339 ppb. The three greenhouse gases show seasonal cycles and long-term increasing trends using data from NOAA ESRL. The global mean surface temperature anomaly record also exhibits decadal variability and a long-term increasing trend. All graphs are rising and shown in four different colors, including white, yellow, orange, and pink.

Op een zomerse zondagmiddag in de Twijnstraat.

Foto van de Twijnstraat in Utrecht, één van de oudste winkelstraten in Nederland. De zon werpt schaduwen op de bestrating en door de weerkaatsing van het licht in de ramen lijkt het alsof de schaduwen ook ramen hebben.

Top panel: A model train appears crushed against the face of a sleeping orange and white cat, whose head rests heavily on the miniature tracks.

Bottom panel: A cartoon depiction of the train's interior shows exaggerated passengers; one is panicked by the impact, while another smiles calmly, looking out the window at the cat's face.

@queroseno just hold on, they'll germinate when they like the condition you've put them in. maybe add another week of patience?

@queroseno fresh jalapeño seeds can sprout really fast, in about a week. warmth ~20° C and light will help 🌱

heptacodium or not a heptacodium, that's the question 🌱

You can also see structures (mountains, rims of craters and impact basins, etc.) at the lunar limb.

There are also sunspots (and groups of them) and solar faculae on the surface of the Sun.

Enlarged section of the picture of the solar eclipse. The limb of the moon appears slightly jagged.
