Hello Stranger?
I took this photo recently on a hike on one of my local hills when I turned around and saw a stranger walking there.
I hardly ever have people in my photos, because I don't WANT people there. But this scene was so different.
The fog was just thick enough to see the person, yet I didn't feel like the person was "near". It all just felt so distant.

What a sight! The #NorthernLights were clearly visible in the skies above #Goettingen last night. Here are some shots captured by #mpsgoettingen employees. Enjoy!
And…
21 kWh generation yesterday despite significant clouds, another new record. I think we actually got pretty much the optimal conditions in the afternoon: no clouds around the sun (so direct sunlight hits some of the panels where it's not shaded by trees), but clouds in most of the rest of the sky sending additional scattered light down towards the panels not pointed right at the sun.
We hit a peak of 4.4 kW generation, not quite enough to make up for our 5.6 kW demand at that moment…
Spring is here. A couple of days ago I saw some pterodactyls (herons) carrying twigs to their nests in a huge tree; today some trees in front of my house were showing those pinhead pink blossoms that come out before the leaves.

Some photos from today's hike in the mountains. To escape the fog.
It was very very icy at the bottom. And I was super happy to have my micro spikes.
The way up was pretty calm. Right the #silentsunday I had desired. At the summit there were a bit too many people and I didn't see proper motives. So I just enjoyed the view and the really warm temperature.

From Family Trees to Qualified Immunity: Reflections at 200 Weeks
In my 200th consecutive weekly post, I reflect on a major genealogy discovery, the realities of AI-generated fiction, and the troubling doctrine of qualified immunity—where “functionally identical facts” can determine whether civil rights violations ever see accountability.

Planting trees in the sea could act as a huge carbon sink and save millions of dollars in storm damage every year.
What is stopping us from doing it?
A new study reveals restoring mangroves could save $800 million in storm damage,
protect 140,000 people from flooding,
and remove almost triple the amount of CO2 produced by cars in the U.S. every year
Some of the trees in my neighborhood have decided it's spring. Some of the neighbors still have winter-holiday lights up to decorate their houses. They're both wrong -- those trees' blossoms are probably going to be frozen before the month's out, and it is long past time to have removed any winter-holiday outdoor lighting.

Local Computation Algorithms for (Minimum) Spanning Trees on Expander Graphs
Pan Peng, Yuyang Wang
https://arxiv.org/abs/2602.07394 https://arxiv.org/pdf/2602.07394 https://arxiv.org/html/2602.07394
arXiv:2602.07394v1 Announce Type: new
Abstract: We study \emph{local computation algorithms (LCAs)} for constructing spanning trees. In this setting, the goal is to locally determine, for each edge $ e \in E $, whether it belongs to a spanning tree $ T $ of the input graph $ G $, where $ T $ is defined implicitly by $ G $ and the randomness of the algorithm. It is known that LCAs for spanning trees do not exist in general graphs, even for simple graph families. We identify a natural and well-studied class of graphs -- \emph{expander graphs} -- that do admit \emph{sublinear-time} LCAs for spanning trees. This is perhaps surprising, as previous work on expanders only succeeded in designing LCAs for \emph{sparse spanning subgraphs}, rather than full spanning trees. We design an LCA with probe complexity $ O\left(\sqrt{n}\left(\frac{\log^2 n}{\phi^2} d\right)\right)$ for graphs with conductance at least $ \phi $ and maximum degree at most $ d $ (not necessarily constant), which is nearly optimal when $\phi$ and $d$ are constants, since $\Omega(\sqrt{n})$ probes are necessary even for expanders. Next, we show that for the natural class of \emph{\ER graphs} $ G(n, p) $ with $ np = n^{\delta} $ for any constant $ \delta > 0 $ (which are expanders with high probability), the $ \sqrt{n} $ lower bound can be bypassed. Specifically, we give an \emph{average-case} LCA for such graphs with probe complexity $ \tilde{O}(\sqrt{n^{1 - \delta}})$.
Finally, we extend our techniques to design LCAs for the \emph{minimum spanning tree (MST)} problem on weighted expander graphs. Specifically, given a $d$-regular unweighted graph $\bar{G}$ with sufficiently strong expansion, we consider the weighted graph $G$ obtained by assigning to each edge an independent and uniform random weight from $\{1,\ldots,W\}$, where $W = O(d)$. We show that there exists an LCA that is consistent with an exact MST of $G$, with probe complexity $\tilde{O}(\sqrt{n}d^2)$.

Here’s a half-block stretch in the Avenues with no trees.
Legislation by Mayor Lurie and Alan Wong made it harder to remove these driveways by allowing them to remain when garages are converted to housing.
Now the Lurie-Wong legislation to let developers not plant trees and limit tree removal appeals is going to Planning Commission tomorrow.

Geometry study (shadows are weird).
Back story: In some parts of Vancouver, if you’re putting up a new building (typically condo/retail) you can get tax breaks or more square feet or some such bonus if you preserve the original facade. This place was torn down quite a while ago but the facade, propped up by the metal framework, remains. A policy misfire in this case because it was a really crappy brick frontage and would not be missed.

When I saw the topic, I wasn't sure wether I should post a mountin photo or not. But as I have seen so many others doing so, I decided to also post this "view from above" from ~3 months ago when I went to this mountain and enjoyed not only the silence but also the view.
Enjoy!

I might also have to check the nature & wildlife protection zones first.

Today in the drizzle I stopped by the Living Library, a beautiful native plant garden near SF's Balboa Park at the San Jose/Seneca intersection. Highly recommend a visit to see some #ceanothus in bloom and California poppies and island mallows beginning to, and much more.
It's been quite a day today. Quite ... challenging. But with a good end.
The mood of this photo is now exactly what I needed: a calm, chill hike in low hanging clouds. Just a few people - no stress, no expectations, no talking, no phone ...

My #silentsunday.. I only had a chat with two guys at the summit and one guy a bit below.
Besides that... 4-5h silence. If we don't count the minutes I was following the activities of a woodpecker a couple of meters away from me 😊
It took me really efforts to get out. But - as usual - it was worth it.

Just a little one and a half hour walk nearby before it was supposed to be raining (and rugby starts).
It was a nice walk and good to be out. Strangely, my old GPS device refused to get a location despite having lots of satellites. Just 10min before coming back (after a couple of restarts and taking the batteries out and back in) it worked.
Fortunately, I only had it with me to test if my heart rate monitor also connects to it.

Almost exactly 2 years ago when it was below -16°C.
This was a real cool experience - literally.
But I'm just so glad that I went there. I think, this waterfall isn't frozen like that so often. So I was just really lucky to be at the right time at the right spot.
And now - enjoy your weekend 😉

Obviously it was quite foggy and cold!
On location I was already pretty sure that these would be monochromes. but I struggled to really see motives at first. Luckily I went there just to take photos, not hiking.
Sometimes I just stood there for a while and was looking around to ... see whats around.

I almost didn't make it out but finally went to the mountains.
By the time I came there I was really happy that several peoplpe went this trail before. Otherwise ... I'm not sure if I would have gone there without snowshoes to be honest.
Next time, I might really bring snowshoes. …
