Mali: enlèvement de Mountaga Tall, avocat et défenseur de la démocratie
Au Mali, un calme précaire règne sur le terrain. Aucun affrontement n'a été rapporté, depuis le début du week-end du 2-3 mai, alors que les jihadistes du Jnim et les rebelles indépendantistes du FLA sont à l'offensive depuis le 25 avril, dans tout le pays et principalement dans le Nord. La capitale Bamako reste soumise à un blocus partiel instauré par les jihadistes, depuis le 28 avril. Dans la nuit du samedi 2 au dimanche 3 mai, Me Mountaga Tall, avocat, homme politique et ardent dé…

For decades, Mat wasn’t paid for his work.
Enslavers rented him out for $100 a year to a man who wanted to turn the site into a tourist attraction
– what would later become Mammoth Cave national park.
In the mid-19th century, Mat was one of several enslaved guides who became an expert in the hundreds of miles of underground terrain,
leading notable guests like Emperor Dom Pedro of Brazil and Ralph Waldo Emerson through a sprawling labyrinth of dark passageways and ca…

I wanted to explore the topographic relief cartographic style that I did for Santorini, Greece, last year¹ and tried it on the Faroe Islands 🇫🇴.
One new thing is that I worked with @… terrain tiles instead of processing the raw NASADEM data.
Feedback and comments are requested! 🙏

NASA awarded Jeff Bezos' Blue Origin an initial $188 million contract
to get its robotic Blue Moon Mark 1 lander ready to deliver lunar terrain vehicles, or LTVs,
with an option period worth an additional $280.4 million for two task orders.
Carlos Garcia-Galan, program manager for NASA’s Moon Base program, said the LTVs will be
“a mix between the Apollo lunar roving vehicle and the Mars-style rover.”
Each rover will weigh a little less than one metric ton, …

#SilentSunday #Rail #Signs

Looking up at signs on a traffic sign pole. On the back of the pole, facing away from the camera, are two signs in shapes familiar with USA motorists: a letter X indicating a railroad crossing, and a triangle indicating a yield. On the front is a rectangular sign that features the no symbol over a walking person and an all-terrain vehicle. The words read: "Trespassing is dangerous and illegal. Stay off railroad tracks. Ohio Revised Code 4519.40. No trespassing on tracks or right of way". The s…

I sooo often don't have photos of the summit cross when I go to the #mountains . Don't ask me why. Maybe because I usually have people in the photo?
It was the same that day: I almost left without that photo when I stepped over the flowers and thought that they might be a cool foreground for the summit. And by focusing on the flowers and blurring the people, I also don't hav…

This image captures a serene and picturesque mountain summit, blending natural beauty with a touch of human presence. The foreground is dominated by vibrant blue gentian flowers, their striking color standing out against the rugged, rocky terrain. The flowers are in sharp focus, drawing the viewer's attention to their delicate petals and adding a sense of vitality to the scene. The background features a wooden cross, a common marker for mountain peaks, standing tall against the clear blue sky.…

📚 My book review of Concrete Hell: Urban Warfare From Stalingrad to Iraq
Two chapters are relevant, but incredibly thin on theory. The rest is a fairly well written overview of a number of urban operations scenarios, clearly chosen to stress the authors' point, whatever it may be. The whole thing has a sizable US slant. So yes. We have more cities, so wars might happen in places that require fighting in urban terrain. Also, water is wet.

Defensive rewilding could turn wetlands and forests into border barriers #nature

Defensive rewilding could turn wetlands and forests into border barriers
Restoring forests, wetlands and peatlands could help defend national borders as well as tackle climate change, according to new research from the University of East London (UEL). The study introduces the concept of "defensive rewilding"—the intentional, pre- or mid-conflict restoration of ecosystems to shape terrain in ways that can slow, redirect or impede military advances, while delivering environmental benefits.

“Corollary 1 (AoE II is Turing-Complete). Let I be an instance of AoE II with two players p0,p1. Assume p0 has two markets, a town centre, a trade cart, six villagers, and five farms; while p1 has a scout unit and only attacks p0’s buildings. Then if I has no time or size limits and the terrain allows for buildings everywhere, the game session in I is Turing-complete.”

Got a Labu lawn robot a while back here and wow have to say this thing is much nicer than I imagined.
I previously had Hasqvarna here quoting obscene amounts and then went to put aerials, wires and all sorts of shit here. Totally unworkable. We redo what areas here we cut and do things in every year.
Labu just works plus it’s AWD and doesn’t mind my rough terrain - Hasqvarna wanted to spend 2k to flatten the lawn so their machines can work

This image captures a serene and rugged forest landscape, bathed in the soft, warm light of either early morning or late afternoon. The scene is framed by tall evergreen trees, their branches reaching upward and creating a natural canopy. The sunlight filters through the trees, casting a gentle glow and long shadows across the forest floor. The foreground features a rocky, uneven terrain with a mix of exposed rocks, dry grass, and patches of green vegetation. A faint path can be seen winding it…
