Am 6.12.25 gibt es den #FancyCyclistaRide in der Nikoletta-Edition. Start 17 Uhr, Lange Reihe, #Hamburg. Geplant als Lichterfahrt mit anschließendem Picknick im Warmen.

Now this was a gorgeous cycling loop. Temperature was around freezing but luckily just few wind. As you see, the weather was ace. Clouds and fog stayed in the north 🌞
Also tried Knee warmers, which was just right! A very good buy!
I just need a solution against freezing toes. @… ,I bought neoprene toe warmer! The shoes are just a bit tight then, …

And another couple of etch cycles on the PIC12F683 done.
On the home stretch, I've almost got the last of the dielectric off. But I don't want to be too aggressive because ideally I'd get a beauty shot of intact poly across the whole die first, *then* undercut the poly and get a substrate image.
So I'm still doing my usual 2 minutes etch, then image routine. It'll take as long as it takes.

Pleasant conditions out: sunny and windy, cool but not cold. So I ducked out of the office for an afternoon runabout on the greenway.
Followed it up with a walkabout while talking to my sister on the phone.

Data-Model Co-Evolution: Growing Test Sets to Refine LLM Behavior
A long-standing challenge in machine learning has been the rigid separation between data work and model refinement, enforced by slow fine-tuning cycles. The rise of Large Language Models (LLMs) overcomes this historical barrier, allowing applications developers to instantly govern model behavior by editing prompt instructions. This shift enables a new paradigm: data-model co-evolution, where a living test set and a model's instructions evolve in tandem. We operationalize this paradigm in an int…

Vandermonde Cells Through the Lens of Positive Geometry
We study the geometric and algebraic structure of Vandermonde cells, defined as images of the standard probability simplex under the Vandermonde map given by consecutive power sum polynomials. Motivated by their combinatorial equivalence to cyclic polytopes, which are well-known examples of positive geometries and tree amplituhedra, we investigate whether Vandermonde cells admit the structure of positive geometries. We derive explicit parametrizations and algebraic equations for their boundary …

The high order spectral radius of graphs without long cycles or paths
In 1959, Erdős and Gallai established two classic theorems, which determine the maximum number of edges in an $n$-vertex graph with no cycles of length at least $k$, and in an $n$-vertex graph with no paths on $k$ vertices, respectively. Subsequently, generalized and spectral versions of the Erdős-Gallai theorems have been investigated. A concept of a high order spectral radius for graphs was introduced in 2023, defined as the spectral radius of a tensor and termed the $t$-clique spectral rad…
