Solar electricity every hour of every day is here and it changes everything | Ember
Batteries are now cheap enough to unleash solar energy’s full potential, getting as close as 97% of the way to delivering constant electricity supply 24 hours across 365 days cost-effectively in the sunniest places.

Xogot Pricing Update: Free Trial, Lower Prices, and Lifetime Unlock
It’s been just over two weeks since we launched Xogot, bringing the ability to edit and run Godot projects natively on iPad to the Apple App Store. Thousands of developers have downloaded Xogot in that time, and the app has ranked consistently among the top downloads in the App

Counter-example to Conjectures on Complemented Zero-Divisor Graphs of Semigroups
In this paper, we are motivated by two conjectures proposed by C. Bender et al.\ in 2024, which have remained open questions. The first conjecture states that if the complemented zero-divisor graph \( G(S) \) of a commutative semigroup \( S \) with a zero element has the clique number three or greater, then the reduced graph \( G_r(S) \) is isomorphic to the graph \( G(\mathcal{P}(n)) \). The second conjecture asserts that if \( G(S) \) is a complemented zero-divisor graph with the clique numbe…

Adaptive Anomaly Detection in the Presence of Concept Drift: Extended Report
Data changes to reflect evolving user behaviour, preferences, and changes in the environment. Such changes may occur due to expected shifts in the data distribution, i.e., concept drift, or unexpected anomalous changes. The presence of concept drift poses challenges for anomaly detection in time series. While anomalies are caused by undesirable changes in the data, differentiating abnormal changes from varying normal behaviours is difficult due to differing frequencies of occurrence, varying ti…

Iterating sine, equivalence classes of variable changes, and groups with few conjugacy classes
This is an expository paper about iterations of a smooth real function $f$ on $[0,\varepsilon)$ such that $f(0)=0$, $f'(0)=1$, and $f(x)0$, i.e., the sequence defined by $x_{n+1}=f(x_n)$. This sequence has interesting asymptotics, whose study leads to the question of classifying conjugacy classes in the group of formal changes of variable $y=f(x)$, i.e., formal series $f(x)=x+a_2x^2+a_3x^2+...$ with real coefficients (under composition). The same classification applies over a finite …
