In most enterprise Databricks environments (like in MSC or large analytics ecosystems), system tables such as system.jobrunlogs or system.cluster_events may be restricted or disabled due to security or governance policies. However, tracking cluster utilization and cost is crucial for : Understanding how efficiently jobs use compute Identifying idle clusters or cost leaks Forecasting infrastructure budget Building custom cost dashboards This blog demonstrates a step-by-step approach to compute cluster utilization and cost using only Databricks REST APIs — no […]

arXiv:2601.04261v1 Announce Type: new Abstract: The widespread adoption of Large Language Model (LLM) in commercial and research settings has intensified the need for robust intellectual property protection. Backdoor-based LLM fingerprinting has emerged as a promising solution for this challenge. In practical application, the low-cost multi-model collaborative technique, LLM ensemble, combines diverse LLMs to leverage their complementary strengths, garnering significant attention and practical adoption. Unfortunately, the vulnerability of existing LLM fingerprinting for the ensemble scenario is unexplored. In order […]

Every technologist, at some point, is tempted by the idea of creating a digital version of themselves. Not a simple chatbot that answers questions, but a true digital persona — an AI that doesn’t just know what you know, but thinks how you think. This project, which I call Damian AI, was my attempt to build just that: a conversational agent grounded in my public work and architected to mirror my own systematic, logic-driven cognitive model. The journey was a […]

arXiv:2601.03325v1 Announce Type: new Abstract: Identifiability is central to the interpretability of deep latent variable models, ensuring parameterisations are uniquely determined by the data-generating distribution. However, it remains underexplored for deep regime-switching time series. We develop a general theoretical framework for multi-lag Regime-Switching Models (RSMs), encompassing Markov Switching Models (MSMs) and Switching Dynamical Systems (SDSs). For MSMs, we formulate the model as a temporally structured finite mixture and prove identifiability of both the number of regimes and the […]

Solana’s high-speed platform is fast becoming the preferred home for independent AI programmes. It comes at a time when advanced uses of technology have led to significant increases in cyberattacks. This article details the escalating malware threats for the cryptocurrency community. According to the most recent data on December 5, 2025, the Solana price on Binance hovers around $134.95, facing tight consolidation before a potential breakout. Cryptocurrencies now confront a serious new class of digital adversary. You see […]

arXiv:2601.04272v1 Announce Type: new Abstract: The paper introduces a basic logic of knowledge and abduction by extending Levesque logic of only-knowing with an abduction modal operator defined via the combination of basic epistemic concepts. The upshot is an alternative approach to abduction that employs a modal vocabulary and explores the relation between abductive reasoning and epistemic states of only knowing. Furthermore, by incorporating a preferential relation into modal frames, we provide a non-monotonic extension of our basic framework […]
