cargo-audit breaking build pipelines because of dependency change

I love Rust, but sometimes things like this drive me crazy; I'm now staring down the barrel of a load of CI/CD pipeline failures because apparently cargo-audit has a dependency (kstring) that is so goddamned bleeding-edge it will only support Rust 1.96 or later. I guess the solution is to version pin cargo-audit and specify --locked to version pin its dependencies as well. That feels wrong somehow (audit is the one thing I intuitively DON'T want to version lock, I want the build to break for gen

Coding rust on cloud

I am sure that there is a way to code rust on the could, but is it practical? My laptop broke and now I am on an old and slow pc and I don't want to burden the pc more so I can't download rust nor compile rust code (for obvious reasons), so i've been wondering how could I still code in rust. submitted by /u/Street-Fan4371 [link] [comments]

Earning taste and judgment

Taste used to be a byproduct of the reps. Agents took the reps. So if you're junior you now have to go get the taste and judgment on purpose. A builder's look at the weakening entry level, the two debts we now owe, and concrete ways to build judgment when the machine writes the code.

Why Now: The Eight-Year Wait for Unified Observability

From TypeScript to Rust at 16

Hi everyone! I'm Shrey Vats, a 16-year-old developer from India. I've been programming for about 1.5 years. I started with TypeScript, React, and a little Python, but after a while I realized I wanted to understand software at a deeper level instead of only building web apps. That's what led me to Rust, and I've been learning it seriously for the past few months. So far, I've learned concepts like: - Ownership and borrowing, - Structs and enums - Basic error handling - Lifetimes - A little bi

Final Authority in AI Governance: Frontier-Provider Sovereignty and Action-Centered Deployer Governance

arXiv:2607.13040v1 Announce Type: new Abstract: This paper examines where final authority should sit once capable AI systems are embedded in organizational workflows. It compares two governance models. The first, frontier-provider sovereignty, assigns privileged authority to the provider of the most capable models and is reflected in contemporary arguments for frontier-model testing, release gating, transparency duties, and compute-related controls. The second, action-centered deployer sovereig

Designing Safety-Constrained LLM Systems for Public Health Information Access

arXiv:2607.13038v1 Announce Type: new Abstract: We present the design and implementation of a safety constrained large language model (LLM) system for public health information access, focusing on maternal and child health (MCH) resource navigation. While LLM based systems offer flexible and natural interfaces for information retrieval, their deployment in healthcare contexts introduces risks related to safety, trust, and uncontrolled generation. This work explores practical design patterns for

Rust embedded support

Hi, I wanted to know how good Rust supports writing code for embedded devices. Mostly asking for Raspberry Pi devices, but a general answer is also welcome. Asking this because I'm in the process of writing my own programming language (a transpiler), whose backend is Rust, and wanted to see if I could run or write code in it, since it all translates to Rust in the end. Also wanted to know your experience in writing with it if possible, and if any issues you would have faced writing with it. Th

LessonBench-V1: A Benchmark Dataset for Evaluating AI Lesson Generation Agents

arXiv:2607.13041v1 Announce Type: new Abstract: Large Language Model (LLM) based AI educational content generation systems are increasingly being developed, yet no standardised benchmark exists to systematically evaluate them. This study introduces LessonBench-V1, a benchmark dataset comprising 647 human-written lessons paired with LLM-based reverse-engineered lesson plans across 240 STEM topics spanning mathematics, physics, chemistry, and computer science. The lessons are drawn from 97 truste

Ever had your AI agent burn cycles pulling down that same documentation, understanding it, and summarizing it, before it finally responds? If you’ve experienced either, then you’ve probably watched the

CSTA 2026 Day Three

Today's opening keynote was all about the new PK-12 Computer Science Education Standards. A lot of work went into these new standards. I really want to dig into them. I did download the PDF but I think it may be easier to use the website. The PDF is 218 dense pages. It sounds like most the curriculum vendors have been tracing the development of the standards so you can probably expect any third-party curriculum to be up to standard soon. Before the keynote, one of the Impact Fellows spoke about

Trapped Ions Make ‘Beautiful’ Qubits, But Will They Scale?

When the U.K.’s University of Cambridge joined forces in March with quantum computing maker IonQ to build a quantum computer, it described the pairing as the university’s “largest-ever corporate research partnership.” The momentous commitment raises and important question: what type of qubits will the machine use? The answer is trapped ions, the technology that underpins College Park, MD-based IonQ’s quantum computers. Trapped ions are one of several methods for building a qubit.

Rust Computer vision

Hello, I’m trying to learn Rust by writing a small computer vision project, but I can’t decide which crates to choose. I want to try out most capabilities that relate to cv like object recognition, tracking, and more. I found some blog posts and searched GitHub and doc.rs for crates, but I’m still uncertain. Some crates that come to mind are: 1. opencv-rust, Rust bindings for OpenCV lib, unstable 2. rust-cv, seems not maintained (correct me if I am wrong) 3. rustCV, seems very new I would

Fault-Tolerant Systems: Why Modern AI Workflows Need Better Failure Isolation

Traditional software engineering approaches reliability as a binary state of uptime and downtime. Modern ML pipelines render this paradigm obsolete. Today, architects must deploy robust fault-tolerant systems capable of managing the unique, nondeterministic complexities inherent to AI. In traditional environments, hardware redundancy often satisfies baseline reliability metrics. Today’s AI infrastructure requires isolating algorithmic drift, API degradation, and data pipeline bottlenecks be

Now Is the Time to Give LLMs Access to the ACM Digital Library

As AI systems increasingly become a primary interface through which knowledge is discovered and used, the Association for Computing Machinery (ACM) must decide how to engage with these technologies in a manner consistent with its mission and the long-term interests of the computing community. ACM has intentionally taken a cautious approach. Rather than rushing to monetize content, ACM prioritized protecting the integrity of the ACM Digital Library and understanding the views of authors and volun

This is the repo: https://github.com/coniferprod/today-rs The Today repo starts where the book ends, and I hope to develop the program further on its own track. The book's sample code has its own repository: https://github.com/coniferprod/learn-rust, and I will update that only to correct

It wll eventually handle things like project indexing, AST analysis, dependency graphs, symbol resolution, technical debt analysis, and later Ai assisted refactoring. My current plan is to use Tauri for the desktop app, Tree sitter for parsing, and probably Rayon for parallel indexing anal
