Growing Harness is a failure‑guided training paradigm that learns reusable executable code for LLM agents, turning recurring control logic into a shared harness while reserving model calls for task‑specific reasoning.
The method records function‑level execution traces to locate failures, then an optimizer repairs a bounded code window. Successful edits are kept via a held‑out gate that rolls back harmful changes, allowing the harness’s control structure to evolve from task feedback.
MAGIC is a dense‑reward reinforcement‑learning framework that constructs mixed‑granularity agent collaboration graphs, selecting fine‑grained or group roles locally to match subtask needs.
By exploring a combinatorial space of graph constructions with only final‑answer rewards, MAGIC balances detailed control with reusable patterns, enabling dynamic organization of agents without predefined topologies.
SWE‑Serve is a benchmark comprising 53 repository‑grounded inference engineering tasks across six families, runnable on CPU or a single H100 GPU.
The tasks reflect recent production changes to SGLang and evaluate agents on full‑stack feature implementation, covering model support, runtime execution, and public API updates, unlike prior benchmarks that focus on isolated kernels or performance tweaks.

LWN covers RustConf 2026 talks on gccrs, the Rust frontend for GCC, which aims to compile the Linux kernel but is not yet production‑ready.
Presenters highlighted progress on language support and kernel‑specific extensions, noting that further work is needed before gccrs can be used for mainstream kernel builds.
Security updates were released for AlmaLinux, Debian, and Fedora on Tuesday, covering dozens of packages across the three distributions.
The AlmaLinux update includes libraries such as apr-util and curl, as well as services like sudo and openssh. Debian’s update is limited to the Chromium browser. Fedora’s list spans multimedia, development, and system tools, reflecting a broad maintenance effort.
Hackaday explains how paleontologists estimate the body temperature of Tyrannosaurus rex using fossil evidence and physical modeling.
The article reviews methods such as isotopic analysis of bone phosphate and comparisons with modern ectotherms and endotherms. It highlights uncertainties due to diagenetic alteration and the limited sample size of well‑preserved specimens.
A digital upgrade enables the Sitina B220M medium‑format camera to operate with modern 21st‑century workflows.
The retrofit adds electronic shutter control and USB‑C connectivity while preserving the camera’s large‑format optics. The modification aims to make the system portable enough for field work without sacrificing image quality.
A discarded window‑air‑conditioner was converted into a ground‑source heat pump for residential heating and cooling.
The project repurposes the compressor and refrigerant loop to exchange heat with the earth, improving seasonal efficiency. Installation required custom piping and a control algorithm to balance heating and cooling demands.
Hydrozoan introduces a DAG consensus protocol with dual commit paths, achieving two‑message delay when ≤p validators are faulty and three‑message delay otherwise, on n = 3f + c + 2p + 1 validators.
The protocol works under a hybrid fault model of f Byzantine and c crash‑faulty validators, allowing multiple leaders per round. A novel graded indirect rule reconciles the two paths on the same DAG, ensuring consistent decisions without view changes. Experiments show geographic placement influences which path is faster.

Evaluation shows improved node utilization compared to traditional memory‑centric allocations.
Flux scheduler reduces LLM training iteration time by up to 10× by aligning optical circuit‑switch reconfigurations with compute phases.
Flux reuses existing circuits and amortizes reconfiguration latency behind overlapping compute and communication, making it effective across a range of switch speeds. The approach contrasts with prior OCS schedulers that ignore the compute timeline, leading to under‑utilized bandwidth and larger buffers. Simulations on typical LLM workloads confirm the performance gains.

The authors identify two optimal classes of possible worlds that capture both statistical plausibility and probabilistic uncertainty. They provide tractability results for some queries and complexity bounds for others, outlining when efficient evaluation is feasible.
