Components of a Coding Agent

Coding agents like Claude Code employ an agent harness—a scaffold managing six components including tool use, memory, and repo context—to augment LLMs for software engineering. This harness functions as a control loop that leverages reasoning models (LLMs optimized for self-verification) and ensures prompt-cache stabil…

Why it matters

Mastering agent harness design is essential for building or selecting AI-augmented development tools that integrate into cloud-native or startup tech stacks, directly impacting your focus on orchestration and developer productivity.

Lisette a little language inspired by Rust that compiles to Go

Lisette is a Rust-inspired language compiling to Go, featuring algebraic data types, pattern matching, and a Hindley-Milner type system with immutability by default and no nil pointers. It catches Go runtime issues at compile time while maintaining full interoperability with Go's ecosystem. As a senior engineer working with cloud infrastructure and developer tooling, Lisette's compile-time safety enhancements could reduce critical runtime errors in Go-based microservices or AI agent orchestration systems. Evaluate Lisette for Go projects to eliminate nil-related bugs and leverage stronger type guarantees without sacrificing ecosystem compatibility.

Show HN: sllm – Split a GPU node with other developers, unlimited tokens

Running DeepSeek V3 (685B) requires 8×H100 GPUs which is about $14k/month. Most developers only need 15-25 tok/s. sllm lets you join a cohort of developers sharing a dedicated node. You reserve a spot with your card, and nobody is charged until the cohort fills. Prices start at $5/mo for smaller models. The LLMs are completely private (we don't log any traffic). The API is OpenAI-compatible (we run vLLM), so you just swap the base URL. Currently offering a few models. Comments URL: https://news.

AWS engineer reports PostgreSQL perf halved by Linux 7.0, fix may not be easy

Linux 7.0's restriction to full and lazy preemption models causes PostgreSQL throughput to drop to 0.51x on Graviton4 due to increased spinlock wait times. An AWS engineer proposed restoring PREEMPT_NONE, but kernel maintainer Peter Zijlstra insists PostgreSQL must adopt RSEQ time slice extensions. With Linux 7.0 stable releasing in two weeks and powering Ubuntu 26.04 LTS, this regression may persist until PostgreSQL updates. PostgreSQL is a staple in cloud-native data layers, and a 50% throughput drop from kernel changes threatens the scalability and cost-efficiency of services you architect on AWS or GCP infrastructure. Benchmark your PostgreSQL deployments against Linux 7.0 kernels now and plan to enable RSEQ extensions or lobby for upstream patches to avoid production degradation.

I built a database in France because the Cloud Act makes EU data sovereignty impossible

US surveillance laws (PATRIOT Act, Cloud Act, FISA 702) grant extraterritorial data access, conflicting with GDPR Article 48 and forcing EU developers in regulated sectors (healthtech, AI/ML RAG) to adopt sovereign architectures. VelesDB exemplifies this shift as an EU-hosted database designed for GDPR, Data Act, and AI Act compliance without US cloud dependencies. As an AI/ML engineer or architect handling EU data, US cloud providers expose you to legal conflicts between US surveillance laws and EU regulations, requiring architectural alternatives for compliance. Architect AI/ML data pipelines with EU-sovereign databases like VelesDB to ensure GDPR compliance and avoid Cloud Act jurisdiction.

The Hack That Exposed Syria’s Sweeping Security Failures

Hacked Syrian government X accounts—including the presidency’s General Secretariat and Central Bank—revealed systemic credential reuse and absent multifactor authentication, where a single compromised recovery email could control multiple ministries. Experts cite centralized access without safeguards as a critical flaw, underscoring risks when states rely on commercial platforms for official communication. Demonstrates how basic security oversights in SaaS-dependent infrastructure create single points of failure, directly relevant to engineering teams managing cloud-hosted services and third-party integrations. Enforce MFA and segment credential management across all third-party platform accounts to prevent cascading breaches.

How many products does Microsoft have named 'Copilot'?

Microsoft's 'Copilot' branding now encompasses at least 75 distinct products, from GitHub Copilot and Windows Copilot to Copilot Studio for agent building, spanning apps, hardware keys, and entire laptop categories. The author mapped these via an interactive Flourish visualization after finding no official Microsoft catalog. This naming sprawl complicates product differentiation and developer tooling choices. This naming chaos directly impacts your tooling decisions and clarity when evaluating Microsoft's AI/ML offerings for agent orchestration or development workflows. Map Microsoft's Copilot variants to your specific AI/agent development needs before committing to any platform.

Apple approves driver that lets Nvidia eGPUs work with Arm Macs

Apple signed Tiny Corp's driver enabling both Nvidia and AMD eGPUs on Arm Macs for LLM inference, requiring Docker compilation and avoiding System Integrity Protection disable. This approval represents a rare accommodation for third-party GPU acceleration on macOS, tailored specifically for AI workloads rather than general use. As a senior engineer focused on AI/ML orchestration, this driver unlocks local, high-performance LLM development on Macs without security compromises, potentially reducing cloud dependency for prototyping. Assess Tiny Corp's Docker-compiled driver for integrating eGPUs into your macOS-based LLM training or inference pipelines.

Why SSH Key Management Is Broken and How Certificates Fix It

SSH certificate-based authentication, available in OpenSSH since version 5.4 (2010), solves scaling issues by using a Certificate Authority (CA) model. Deploy separate user and host CAs to sign keys with expirations (e.g., ssh-keygen -s host_ca -h -V +52w), then configure servers with HostCertificate and clients with @cert-authority in known_hosts to eliminate manual key distribution and host fingerprint prompts. As a senior engineer managing cloud infrastructure and developer tooling, replacing manual SSH key sprawl with certificate-based auth directly reduces operational overhead and security risk in team access and host trust workflows. Replace authorized_keys with SSH certificates by establishing separate user and host CAs, signing keys with bounded validity, and configuring sshd/known_hosts to trust only the CA.
