Scientific models are rarely non-trivial merely because they are written down from definitions. Their explanatory and predictive force usually comes from importing deep mathematical or conceptual structure into a target domain. This paper proposes a formal meta-theory of scientific non-triviality based on the idea that successful scientific modeling is often driven by three distinct mechanisms: e…

For years, Kubernetes has been marketed as the platform that solves infrastructure at scale. It automates deployments, recovers from failures, scales applications, and provides a consistent environment regardless of where workloads run. Yet talk to enough engineering teams, and you'll hear a very different story. "Our cloud bill doubled." "We're running twice as many worker nodes as expected." "O…

A recent KNX-AM segment spotlights a collaboration between USC football and students and one alumnus from the Daniel J. Epstein Department of Industrial & Systems Engineering, or ISE. Supervised by ISE Associate Professor of Practice Bruce Wilcox, the team is building a searchable database of play-by-play results from thousands of college football games. The goal: spend less time wrangling data a…

Cross-post. Original: stellarbytecapital.com/blog/cross-border-payment-system-design A payment system has one job that dwarfs all the others: never lose track of money. Features, UI, and even uptime are negotiable in a pinch — a lost or duplicated transaction is not. Cross-border adds currencies, multiple payment channels, settlement delays, and regulators on top. Get the money-safety core right …

Craft externalizes nothing and transfers by apprenticeship. Engineering writes the governing relation down where someone else can find it wrong. Four times now I have written the same three sentences in different notations, for four problems that looked unrelated: a design method, a coding technology, an architecture-derivation procedure, and a contract-modelling tool. I noticed the repetition on…

dc.title: Real-time inverse solutions for digital twins dc.description.abstract: Digital twins require rapid data assimilation for digital state updating and downstream tasks, such as prediction and control. For many physical systems, the data assimilation task requires the solution of a partial differential equation (PDE)-constrained inverse problem, which is often computationally intractable in…

I built this delivery dispatch service to practice and master core backend engineering fundamentals in NestJS. Instead of just building a basic CRUD API, I wanted to understand how real-world dispatch systems manage state transitions, handle route assignments, and keep data consistent under concurrent requests. The backend is engineered with NestJS, TypeORM, and PostgreSQL running inside Docker c…

Detect common symbols in piping and instrumentation diagrams, then use OCR to extract text from instrument-related regions.

USC Viterbi’s Karmel S. Shehadeh introduces a framework to help organizations better balance procurement cost, shortages, and waste under uncertainty. The post A New Model to Improve Resource Planning and Allocation appeared first on USC Viterbi | School of Engineering .

Many engineering teams treat reliability as 'everyone's responsibility.' In practice, that means it's nobody's responsibility. Here's why you need someone whose job is specifically to care about it. The 'everyone owns it' myth It sounds great. In reality, every product engineer has a feature deadline. When the deadline competes with reliability work, the deadline wins every time. Reliability beco…

Researchers have demonstrated a way to drastically accelerate resource allocation solutions from large-scale optimization models - while still producing near-optimal results.

This week, I presented this paper at ICCCN'26. This is joint work with Aleksey Charapko (University of New Hampshire) and my MongoDB colleagues Matt Broadstone, Daniel Gomez Ferro, and Akshat Vig. The paper investigates how to build a metastability tolerant execution control system (ECS) for a database. Why? Modern databases are complex networked systems serving mixed workloads: short queries (th…

When scaling multi-agent AI ecosystems across asynchronous cloud boundaries, traditional RPC calls break down . Network partitions, rate limits, and non- deterministic agent executions often result in silent state corruption or phantom side-effects. > "In distributed agentic systems, non-determinism must be isolated at the ingestion boundary. If an effect cannot be cryptographically witnessed, it…

Researchers from University of Lübeck published a technical paper titled “SPARC: Automated Root-Cause Analysis of Pre-Silicon Power Side-Channel Leakage in the Processor Design Flow.” Abstract Excerpt: “This paper presents SPARC, an automated framework for pre-silicon PSCL evaluation and root-cause analysis. SPARC leverages macro-cell-level Information Flow Tracking (IFT) augmented with enhanced …

The Pre-Testbench Verification Checklist: ✅ 1. Spec version locked — Which version of the spec is RTL implementing? If it's not locked, you're verifying a moving target. ✅ 2. Interface list finalized — All clocks, resets, interfaces, and their reset polarity documented. Surprises here cost days. ✅ 3. Functional coverage model drafted — Write your covergroups before writing your driver. Coverage-f…

Disclosure: I run Auto-Respond, an AI lead-response tool for home-service businesses. This post is about the problem, not a pitch. The product link sits at the bottom. Most "lead management" advice treats speed as a nice-to-have. For local service businesses it is close to the whole game, and it turns out to be an interesting systems problem. The number that matters Dr. James Oldroyd's lead-respo…
