I never posted another "garage door fix" post after this one because we ended up getting a new garage door opener when the old one started failing even more and was beyond repair and also my partner was fed up with my hacks.

Amazon Threat Intelligence observed sustained targeting of global infrastructure between 2021-2025, with particular focus on the energy sector, by Russian state-sponsored threat actors.

Amazon Threat Intelligence identifies Russian cyber threat group targeting Western critical infrastructure | Amazon Web Services
As we conclude 2025, Amazon Threat Intelligence is sharing insights about a years-long Russian state-sponsored campaign that represents a significant evolution in critical infrastructure targeting: a tactical pivot where what appear to be misconfigured customer network edge devices became the primary initial access vector, while vulnerability exploitation activity declined. This tactical adaptation enables the same […]

Adversarial Defense in Cybersecurity: A Systematic Review of GANs for Threat Detection and Mitigation
Machine learning-based cybersecurity systems are highly vulnerable to adversarial attacks, while Generative Adversarial Networks (GANs) act as both powerful attack enablers and promising defenses. This survey systematically reviews GAN-based adversarial defenses in cybersecurity (2021--August 31, 2025), consolidating recent progress, identifying gaps, and outlining future directions. Using a PRISMA-compliant systematic literature review protocol, we searched five major digital libraries. From 8…

Horizon-scale variability of M87* from 2017--2021 EHT observations

Horizon-scale variability of M87* from 2017--2021 EHT observations
We report three epochs of polarized images of M87* at 230\,GHz using data from the Event Horizon Telescope (EHT) taken in 2017, 2018, and 2021. The baseline coverage of the 2021 observations is significantly improved through the addition of two new EHT stations: the 12\,m Kitt Peak Telescope and the Northern Extended Millimetre Array (NOEMA). All observations result in images dominated by a bright, asymmetric ring with a persistent diameter of $43.9\pm 0.6\,\muas$, consistent with expectations …

A note on the relation between one--step, outcome regression and IPW--type estimators of parameters with the mixed bias property

A note on the relation between one--step, outcome regression and IPW--type estimators of parameters with the mixed bias property
Bruns-Smith et al. (2025) established an algebraic identity between the one-step estimator and a specific outcome regression-type estimator for a class of parameters that forms a strict subset of the class introduced in Chernozhukov et al. (2022), assuming both nuisance functions are estimated as linear combinations of given features. They conjectured that this identity extends to the broader mixed bias class introduced in Rotnitzky et al. (2021). In this note, we prove their conjecture and fur…

A transmission hologram for slitless spectrophotometry on a convergent telescope beam. Optimisation and characterization
This article details the optimisation and the characterisation of the hologram described in a companion paper published in 2021, which showed the superiority of a holographic optical element over a periodic grating as a disperser installed in the path of a converging beam on an on-axis detector (unbent spectrograph) for slitless spectroscopy. In this article, we describe in detail the development and optimisation of the final optical holographic element installed on the spectrograph of the auxi…

Bi-Lipschitz embedding properties of lamplighter graphs on weighted and unweighted trees
In 2021 Baudier, Motakis, Schlumprecht, and Zsák proved that if a sequence of graphs $(G_k)_{k\in{\mathbb{N}}}$ contains the sequence of complete graphs with uniformly bounded distortion, then the sequence of lamplighter graphs on $G_k$'s contains Hamming cubes with uniformly bounded distortion and asked whether the converse holds. They suggested that a sequence of trees with edges replaced by paths of ``moderately growing'' lengths may be a counterexample. We prove that indeed this is the…

Vaccinating Now or Vaccinating Later: Separating Pull-Forward and Net Effects Using a Dynamic Regression Discontinuity Design
We study the impact of a novel COVID-19 vaccine mandate, targeting graduating high-school students, on first vaccine uptake. In 2021, the State Government of Western Australia (WA) required attendees at "Leavers" -- a large-scale state-supported graduation party held annually in November in a WA regional town -- to be vaccinated. Using administrative data that link date-of-birth (at the month level), school attendance, and first-dose vaccination records, we exploit the strict school-age laws in…
