Ilford HP5 Plus 400 (FF)

English Alt Text:
A black-and-white overhead view of four people playing badminton on a marked court. The net divides the space, and each player holds a racket, actively engaged in the game. One player is captured mid-swing, striking the shuttlecock. Tables and chairs in the background suggest a courtyard or recreational area. The image conveys energy, movement, and social interaction within a structured play environment.

Ilford HP5 Plus 400 (FF)

English Alt Text:
A black-and-white photograph of a spiral metal staircase viewed from above. The staircase curves downward in a clockwise direction, casting a shadow on the concrete ground below. Patches of grass break up the pavement, and a railing is visible in the corner, suggesting another walkway. The interplay of curves, shadows, and textures creates a visually dynamic and geometric composition.

Ilford HP5 Plus 400 (FF)

English Alt Text:
A dramatic black-and-white photo of a tall high-rise building viewed from below. The building’s grid of windows stretches upward, framed by the dark silhouettes of tree leaves in the foreground. Another building is partly visible on the right. The sky is filled with textured clouds, adding depth and atmosphere. The contrast between rigid urban architecture and organic tree shapes creates a timeless, artistic mood.

Ilford HP5 Plus 400 (FF)

English Alt Text:
A black-and-white photograph of a metal outdoor staircase leading up to a landing. The stairs and railings create sharp geometric shadows on the ground and wall, forming a striking pattern of light and dark. Grass and a sidewalk surround the structure, while a tree stands nearby. In the background, a sculpture shaped like a human figure with outstretched arms adds an artistic element. The composition emphasizes contrast, geometry, and the play of sunl…

Neither #Affinity nor #Darktable seemingly support 1D LUTs, which would have been too easy and useful for my #DigitalNegative preparation tool... Instead they both insist on using only 3D LUT…

$Syntax color highlighted TypeScript source code: ``` import { cycle, map, normRange, permutations, str, take, transduce, } from "@thi.ng/transducers"; // LUT size (number of samples per axis) const N = 9; // example curve of N samples in [0,1] range // (the curve here is y = x^1.2, i.e. a basic darken effect) const curve = [...map((x) => (x ** 1.2).toFixed(4), normRange(N - 1))]; // compute cartesian product to produce RGB tuples const lut = permutations(curve, curve, curve); // alt…$

Kwintesencja polskich lasów w jednym zdjęciu. Nadleśnictwo #Gryfice.
#las #Polska

Trzy tablice na tle lasu. Po prawej napis "leśna ścieżka rekreacyjna" na dwóch drewnianych listwach. Po lewej drewniana tablica z daszkiem, a na niej plakat "Odkrywaj Lasy Nadleśnictwa Gryfice Całą Rodziną. Zapraszamy", ze zdjęciem trzech osób wyłaniających się zza drzewa. Z przodu klasyczna, żółta metalowa tabliczka z napisem "Zakaz wstępu. Uwaga! Ścinka i zrywka drzew. Zakaz obowiązuje od … do …" (dat nie wpisano).

Decentralized and Self-adaptive Core Maintenance on Temporal Graphs
Key graph-based problems play a central role in understanding network topology and uncovering patterns of similarity in homogeneous and temporal data. Such patterns can be revealed by analyzing communities formed by nodes, which in turn can be effectively modeled through temporal $k$-cores. This paper introduces a novel decentralized and incremental algorithm for computing the core decomposition of temporal networks. Decentralized solutions leverage the ability of network nodes to communicate a…

Today's #HamRadio #POTA (Parks On The Air) adventure. Absolutely gorgeous, couldn't-be-better fall weather on a Saturday, so that it was a little surprising that we found parking space and that all the picnic tables were empty. Used my spiderbeam push-up mast to hold my inverted-v link…

Map of my 5W POTA activation. Probably mostly right, but the contact marked as AZ was actually IL.
