hey guys I’m new to this whole subject. As the title says I need help upgrading my GPU. I’m working on my capstone mechanical engineering project, a quadrupedal robot. I decided a few weeks ago that it needed to be trained using Isaac lab. Currently I have isaac sim 6 and isaac lab 3 in a container on my laptop with a 2070. I’m switching to a desktop but what do you guys think is a better GPU […]
Six phases of dbt. SQLMesh added on top. Same Nessie backend, same Iceberg tables, same bronze layer, provably identical gold layer. What I learned the hard way. SQLMesh + Nessie + Trino + Iceberg with full virtual data environments is not clearly documented anywhere. You are reading the first person who built it end-to-end and wrote about it honestly. Most dbt vs SQLMesh articles compare marketing pages. This one is different. The two tools ran simultaneously on the same […]
Markov numbers are integer solutions to x² + y² + z² = 3xyz. The Wikipedia article on Markov numbers mentions that Don Zagier studied Markov numbers by looking the approximating equation x² + y² + z² = 3xyz + 4/9 which is equivalent to f(x) + f(y) = f(z) where f(t) is defined as arccosh(3t/2). It wasn’t clear to me why the two previous equations are equivalent, so I’m writing this post to show that they are equivalent. Examples Before showing the equivalence of Zagier’s […]
A unified encoder for safety moderation and PII detection in a single forward pass, built on top of GLiNER2. 📄 Paper · 🤗 Models Guardrails in an agentic LLM application 5 classifiers × 4 hops = 20 forward passes per request Same application after GLiNER Guard (GliGuard) Most production LLM apps end up with a Guardrail zoo of classifiers and NER. GLiNER Guard (GLiGuard) collapses that into one schema-driven encoder. The Problem Running an LLM in production requires safety moderation and […]

Unmannedaerial vehicle (UAV)-assisted millimeter-wave (mmWave) and terahertz (THz) communications are promising enablers of ultra-reliable and low-latency communication in next-generation wireless networks. However, the initial access and beam alignment process remains challenging because highly directional beams must be rapidly aligned in a three-dimensional environment. In this paper, we investigate a risk-aware beam alignment framework for UAV-assisted mmWave/THz systems, where user equipment scans a 3D spherical region to detect UAV base stations. The objective is to jointly minimize the expected […]
This study examines whether a rubric-guided large language model (LLM) can approximate local human grading practice for text-based responses in three university courses. A total of 930 student responses from Prompt Engineering, Photoshop Design, and AI Video Production were scored by two human instructors and by ChatGPT using the same five-criterion analytic rubric (Accuracy, Logical Flow, Specificity, Quality, and Originality; 0.0–3.0 each; Total 0–15). Human consensus (HC) was defined as the mean of the two human scores and […]
President Trump flew to Beijing, brought Jensen Huang along at the last minute, and left two days later, telling reporters that “something could happen” on chip exports. Nothing did. Not a single Nvidia H200 has shipped to China since Trump first authorised the sales in December 2025, and US Trade Representative Jamieson Greer told Bloomberg that semiconductor controls were not even on the bilateral agenda. The summit theatre obscured a more interesting development underneath it. The H200 isn’t stuck because Washington won’t […]
As skill gaps continue to create headwinds for US businesses fostering growth ambitions, the cause for blockchain adoption and the ability to create smart contracts for more hiring efficiency are growing. According to a report from the McCourt School of Public Policy’s Center on Education and the Workforce (CEW), the United States needs 5.25 million additional workers with training beyond high school through 2032, and 4.5 million will require at least a bachelor’s degree. The report, entitled ‘Falling […]
