This article explains how inline assembly semantics fit into the Rust Abstract Machine by proposing a "storytelling" approach: every inline assembly block must have a corresponding Rust code equivalent that describes its observable behavior, allowing the compiler to reason about soundness and apply optimizations correctly. The author demonstrates why inline assembly cannot arbitrarily violate Abstract Machine constraints like aliasing rules, even though assembly itself doesn't have these concepts.
Article demonstrates how formal verification can detect subtle bugs in code that pass testing and code review, using a banking application example with three classes of defects: fee calculation errors violating invariants, money conservation violations in transfers, and integer overflow edge cases that break properties for all possible inputs.
A former backend lead at Manus proposes replacing traditional function-calling in LLM agents with a single Unix-style run(command="...") tool that leverages pipes and shell operators, arguing that LLMs are naturally aligned with CLI patterns they've seen extensively in training data and that this approach reduces cognitive load on tool selection while enabling composition.

An educational murder mystery game that teaches core dump debugging and reverse engineering through a sci-fi airlock controller scenario. Players must analyze a core dump to uncover how a buffer overflow exploit was used to trigger a fatal airlock malfunction.
This lab exercise demonstrates a reflected XSS vulnerability in an HTML context where standard HTML tags are blocked but custom tags are allowed, requiring attackers to find alternative vectors to achieve code execution.
An AI-generated Slack integration solution triggered the API's 1-request-per-second global rate limit by making hundreds of sequential close calls, cascading to break all application endpoints. The assistant's attempted fix using blocking sleep() worsened the problem by further blocking concurrent operations, demonstrating AI's failure to consider distributed system constraints.
A practical guide combining AI image analysis with ImageMagick command-line blurring to automatically detect and redact sensitive data (credentials, emails, tokens) from screenshots. The workflow uses AI models to identify sensitive regions by coordinates, then applies Gaussian blur or solid fill redaction via ImageMagick's -region flag.
Technical taxonomy of GraphQL attack classes including schema enumeration, batch query abuse, and resolver explosion attacks that are commonly missed by security tools.
A detailed technical comparison of compression algorithms (gzip, zstd, xz, brotli, lzip, bzip2, bzip3) for optimizing code size in resource-constrained environments, demonstrating that bzip/bzip2 achieves superior compression ratios for text-like data through Burrows-Wheeler Transform rather than LZ77, while maintaining a smaller decoder footprint.
A technical guide to setting up Pocket ID, a lightweight OIDC identity provider focused on passkey-based authentication, as a simpler alternative to Keycloak for self-hosted services. The author covers installation, client configuration patterns, and integration with multiple self-hosted applications including Gitea, Argo CD, Grist, Sentry, n8n, and WordPress.
Article explores API design principles optimized for AI agents (agent experience/AX) alongside human developers, emphasizing that good OpenAPI documentation, clear error messages with guidance, and semantic descriptions are critical for autonomous agent routing and error recovery in fintech and accounting integrations.
PHP-rnet is a PHP extension that bypasses bot detection by impersonating real browser TLS fingerprints and HTTP/2 behavior, using Rust-based networking libraries and BoringSSL to avoid the telltale libcurl fingerprint that standard PHP HTTP clients expose.
Cisco security researchers demonstrate critical vulnerabilities in OpenClaw, a personal AI agent framework, including prompt injection, data exfiltration, and command injection attacks via malicious skills; researchers released an open-source Skill Scanner tool to detect security issues in AI agent skills, revealing 26% of analyzed skills contained at least one vulnerability.
A technical tutorial on ublk, a Linux kernel framework for creating virtual block devices in user space using io_uring. The article covers the architecture of ublk servers, worker thread management, and data transfer mechanisms, explaining how io_uring batching amortizes the performance cost of context switching between kernel and user space.
lf-lean presents a verified translation of 1,276 statements from the Logical Foundations textbook from Rocq to Lean using task-level specification generators, achieving a 350x speedup over manual verification. The work demonstrates that verified software engineering can scale with O(1) human oversight effort through automatically-derived correctness specifications, suggesting AI-assisted formal verification may become more practical than human code review.
Mendral describes how they built a specialized CI/CD debugging AI agent that outperforms generalist LLM coding assistants by combining domain-specific context (log ingestion, historical failure patterns, repository metadata) with a custom multi-agent architecture using different Anthropic models (Haiku, Sonnet, Opus) for different cognitive tasks, routed through a custom Go backend with Firecracker VM sandboxing.
A detailed guide on using custom domain-specific languages (DSLs) as security boundaries and trust enforcement mechanisms for LLM agents, with practical examples like Confit SQL—a constrained SQL dialect that prevents agents from executing dangerous queries while maintaining performance and security guardrails.
A practical guide to agentic development covering tool selection, sandboxing, privacy concerns, and workflow optimization using specification-driven development (SPEC.md), skill guidelines (SKILL.md), and iterative planning (PLAN.md) to effectively steer LLM-based coding agents.
Bellingcat exposed a fraudulent evacuation flight scheme promoted by a Dutch newspaper using an AI-generated image of a non-existent person named Tamara Harema. Through photo forensics analysis of the Burj Khalifa background and flight-tracking data, researchers confirmed the flights never existed and the person was fabricated.
Analysis of building a network using only IX route servers (no transit or bilateral peering) reveals 56.6% IPv4 and 61% IPv6 prefix coverage from outbound routes, but only ~14% inbound reachability via ICMP ping testing across 100+ internet exchanges. The article demonstrates significant diminishing returns after the top 5 exchanges and highlights the asymmetry between BGP route visibility and actual traffic acceptance.
Comparative analysis of compression algorithms for minimizing decoder size in constrained Lua environments, demonstrating that BWT-based bzip achieves superior compression ratios and smaller decoders compared to LZ77-based alternatives like gzip, xz, and zstd.
A critical analysis of Erlang's actor model and message-passing concurrency, arguing that despite superior isolation through separate process heaps, Erlang still exhibits the four failure modes of shared mutable state (deadlock, unbounded queue growth, message ordering races, protocol violations) through its mailbox design, with all mitigations requiring programmer discipline rather than language enforcement.
WireGuard is presented as both a VPN application and an independent cryptographic protocol based on Noise Framework and ChaCha20-Poly1305 for encrypting UDP datagrams. The article introduces WireGuardClient, a .NET library that implements the WireGuard protocol as a stateless encryption layer for UDP-based applications without requiring full VPN infrastructure, addressing TCP limitations like head-of-line blocking and connection reset issues on mobile networks.
A penetration test against a custom AI chatbot that chains an XSS bypass with a zero-click account takeover vulnerability, demonstrating how input sanitization failures can lead to complete account compromise without user interaction.
An analysis of SQL order-equivalence in window functions across major database systems, examining whether identical ORDER BY clauses in window functions guarantee consistent row ordering for peer rows. The article reveals that while the SQL standard requires order-equivalent clauses to produce deterministic peer ordering, several database systems violate this guarantee, and proposes solutions for achieving consistent results.
