Speeding up the JavaScript ecosystem - Polyfills gone rogue
Many popular npm packages depend on 6-8x more packages than they need to. Most of these are unnecessary polyfills and it's one of the key reasons node_modules folders are so large. The eslint ecosystem seems to be most affected by this.

Italian researchers found a brilliant way to give old solar panels new life. They're extracting silicon from discarded panels and turning it into a high-performance catalyst using palladium nanoparticles.
The recycled material matched commercial catalysts across six cycles with 97% yield—tackling mounting solar waste while creating valuable chemistry tools.

Scientists just cracked a major solar recycling challenge. A new laser technique cleanly removes backsheets from old solar panels without damaging the valuable silicon and glass underneath.
The method costs just $0.22 per panel and preserves components for reuse—a game-changer for making solar truly circular.

Continuous-wave infrared laser technology enables damage-free backsheet removal in end-of-life solar modules
U.S. researchers have developed an IR-CW laser-based method to remove backsheets from end-of-life silicon solar modules without damaging the glass or wafers, using controlled heating of the silicon–EVA interface through the front glass. The process enables clean mechanical delamination with preserved device performance and offers a lower-energy, lower-cost alternative to conventional thermal or chemical recycling methods.

IMO it's going to get *much* worse before it gets better. The cost of discovery has gone from “months of expert time” to maybe “hours of expert time" with this new wave of tools; and most of the experts *might* not even have access to the “best" tools, yet. (citation needed on that one, but… there are power-multiplier tools, certainly, for people who use them).
I think we've barely scratched the surface on software that is exploitable (spoiler: nearly all of it).

99% of people probably don't use ipsec (and probably shouldn't use it), why do we have ipsec kernel modules installed by default on every linux distro? #dirtyfrag

What is it with standards authors and their design approaches that they so often fall victim to monolithic specs, full of severe feature creep? Why are modern data/protocol standards still not more layered/modularized, with especially niche or just nice-to-have-but-not-essential features delegated to optional layers/modules instead of including them all into the core spec? This kind of unstratified design approach not just acts as an amplifier of complexity, edge cases and unintended interac…

How do you handle custom sensors and modules? In Meshtastic they generally "just work" after setting the pin configuration, but I'm having zero luck. Currently fighting with trying to get a NEO-6M GPS module working with a Heltec V3 radio.

I remembered yesterday that I had already known and implemented a few things I needed to analyze Intel ME Gen 2 binaries.
The load address is in the metada that `intel_fw me show` prints.
Modules can be unpacked and decompressed via unhuffme, which puts the load address in the file name. I will add the Huffman decompression feature to intel_fw, too.
So with the load address and the Ghidra fork, I now get sensible decompiled code and references, e.g. I can see where strings a…

Universal Assembly and Cellular Loop Spaces on Regular CW Complexes

Abstract: We develop a regular CW analogue of the classical assembly formalism for chain complexes appearing in algebraic surgery theory. From the cell poset, we construct combinatorial path and loop objects using fences of comparable cells and prove that their classifying spaces recover the homotopy types of the ordinary based path and loop spaces. The resulting loop object carries a natural monoid structure, giving rise to a DG algebra defined directly from the cellular structure.
For complexes of cellular cosheaves, we introduce a universal assembly functor to modules over the group ring of the fundamental group and study the localization determined by global equivalences. The associated homotopy category is identified with a Verdier quotient of the derived category of cellular cosheaves, and its fibrant objects are precisely the homotopy locally constant complexes. A single elementary cosheaf becomes a compact generator after localization, and its derived endomorphism DG algebra is identified with singular chains on the cellular loop space. Consequently, the localized theory admits a Morita description in terms of DG modules over the loop DG algebra. The formalism provides a regular CW counterpart of the classical delta-set approach to assembly in algebraic surgery theory due to Ranicki and Weiss.

Abstract: Heart disease remains the leading cause of death in the United States, motivating extensive efforts to improve its diagnosis, treatment, and prevention. Over the past decade, computational modeling has emerged as a powerful tool to advance cardiovascular research by enabling detailed, patient-specific studies of cardiac physiology and pathology. svMultiPhysics is an open-source, parallel finite element solver written in C specifically designed for multiphysics cardiovascular problems. It provides a unified framework for simulating the partial differential equations that govern solid mechanics, fluid dynamics, diffusion, and cardiac electrophysiology. These equations can be solved independently or in a coupled fashion, allowing researchers to investigate interactions between physical processes in a modular yet integrated way. The solver's main strength lies in its ability to seamlessly couple multiple physics modules, enabling the study of complex, highly nonlinear systems. For example, svMultiPhysics can capture the interplay between cardiac electrophysiology, myocardial tissue mechanics, and blood flow dynamics, processes that are essential to understanding vascular and cardiac physiology and function in health and disease. Preliminary GPU-enabled simulations show up to approximately $30\times$ wall-clock speedup for selected linear solver configurations over CPU-based simulations. By offering a robust, extensible, and freely available platform, svMultiPhysics empowers researchers to explore multiphysics problems in cardiovascular science. As the primary 3D solver in the SimVascular open source project, it forms a key component of an end-to-end open source software ecosystem for image based patient specific modeling in the cardiovascular system. It is maintained and openly developed on GitHub, fostering transparency, reproducibility, and collaboration.

Color-Rule-Function Encoding for Combinatorial Memory

Abstract: Combinatorial memory is a class of memory in which information is encoded in the set of paths through a structured mesh. In this work, we introduce a systematic encoding framework, referred to as the Color-Rule-Function (CRF) approach, for representing information in combinatorial memory. The method consists of four key steps: selecting a sequence of paths in the mesh, assigning values (e.g., colors) to each cell, defining a set of rules based on the values encountered along each path, and constructing a Boolean function that determines the state of each path. . The coding procedure is illustrated by several examples. The design space scales of the CRF scale fundamentally faster compared to conventional memory. This apparent advantage arises from the use of rule-based and functional representations but is accompanied by increased hardware complexity. A possible hardware realization of the CRF framework is discussed. Importantly, the hardware overhead can be substantially reduced through the use of customized modules. The examples of the customized design are described in the text. The combination of CRF coding with customized module design may lead to a practical advantage in data storage density. According to the estimates, the data storage density may exceed Exabit per centimeter squared. A key problem that requires further investigation is related to the minimum Hamming distance between an arbitrary target bit sequence and the closest sequence realizable within the CRF framework under fixed hardware constraints.

A structural reduction for the symmetric hit problem in four variables

Abstract: Let $\mathcal{A}$ be the mod $2$ Steenrod algebra, and $P(n) = \mathbb{F}_2[x_1, \dots, x_n]$ be the polynomial algebra viewed as an unstable module over $\mathcal{A}$. The symmetric hit conjecture asks whether the symmetrization of a hit monomial in $P(n)$ is always hit in the symmetric invariant subalgebra $B(n) = P(n)^{\Sigma_n}$. While resolved for $n \leq 3$, the case $n=4$ presents significant obstructions due to combinatorial complexity, orbit cancellations intrinsically tied to $\Sigma_4$-stabilizers, and the emergence of strongly spike-free survivor modules. This paper introduces a conditional structural reduction to overcome these obstructions in the domain where the numerical weight satisfies $\mu(d) \leq 4$. By integrating Walker-Wood duality with a new $\Sigma_4$-stabilizer parity analysis, we reduce the global conjecture to localized algebraic conditions: a symmetric lower-spike reduction and a strengthened four-row digital-engineering hypothesis. Assuming these inputs, the conjecture follows by lexicographic induction on the column-sum and row-sum sequences of the binary exponent matrices.
Our approach isolates the four-variable repeated-row anomaly into exact local identities, utilizing global Steenrod-kernel functionals lifted from local spike-free quotients to detect potential survivor elements. Finally, we provide explicit monomial-level computations in degrees $8$, $12$, and $14$, explicitly illustrating the stabilizer mechanism in practice and framing the precise algebraic identities required for a future unconditional proof.
