user-scanner: Open-Source OSINT Tool Unifies Email and Username Profiling

0
·1 views

A Python-based open-source tool called user-scanner has been highlighted as a unified OSINT engine for digital reconnaissance workflows. Unlike older utilities such as Holehe and Sherlock, which handle only email or username lookups separately, user-scanner combines both into a single platform covering over 380 data vectors. The tool features an automated cross-scanning mode that recursively pivots between email addresses and usernames across multiple hops to map linked identities. It also integrates with Hudson Rock's infostealer breach database to flag targets appearing in compromised credential logs. Additional capabilities include TLS fingerprint impersonation via httpx and curl_cffi, proxy support, and export options in PDF, JSON, and CSV formats.

Database Isolation Levels Explained: Why the ANSI SQL-92 Standard Falls Short

In multi-user database systems, concurrent transactions can produce anomalies such as dirty reads, phantom reads, lost updates, and write skew, which corrupt data consistency. To manage these risks, databases offer isolation levels — configurable settings that trade off data safety against performance. The ANSI SQL-92 standard defines four classic isolation levels: Read Uncommitted, Read Committed, Repeatable Read, and Serializable. However, this widely taught standard is considered incomplete, as it omits critical anomalies like lost updates, read skew, and write skew. As a result, some databases that advertise full Serializable isolation actually only implement Snapshot Isolation, potentially leaving applications exposed to subtle data integrity failures.

MCP C# SDK 2.0.0: Why Pinning Protocol Version 2026-07-28 Matters for Stateless Apps

The MCP C# SDK 2.0.0 defaults to the 2026-07-28 protocol but automatically falls back to older versions when connecting to stateful servers, which can silently change the wire contract. The 2026-07-28 specification eliminates the initialize handshake and HTTP sessions, allowing clients to send per-request capabilities via server/discover. When fallback occurs, health checks may stay green while code built on stateless or modern-only assumptions runs under legacy session rules. Developers can enforce a minimum protocol version by setting the ProtocolVersion field in McpClientOptions, causing connections to fail rather than silently downgrade. Inspecting both NegotiatedProtocolVersion and SessionId after connecting is recommended to make any compatibility fallback visible in logs.

Why a HIPAA-compliant edge system chose gRPC over Unix sockets instead of HTTP

A developer building PhotonicOps, an offline telemetry and hardware-triage system for clinical silicon photonic biosensors, faced a key architectural decision on a single-host Apple Silicon edge deployment. The system ingests optical resonance data at 10,000 samples per second and must pass batches of sensor frames from a Go ingestion engine to a Python DSP pipeline without any cloud API calls, due to HIPAA compliance requirements. The core transport question was whether to use plain HTTP on a loopback port or gRPC over a Unix socket for that one internal process-to-process hop. Three concrete, code-level reasons drove the choice away from HTTP: native client-streaming support in gRPC, a strict sub-10ms per-frame processing budget, and the overhead costs of reconstructing similar functionality manually over HTTP/1.1. The article focuses on the reasoning behind the losing option rather than simply advocating for gRPC, framing the tradeoff analysis as the transferable insight for engineers facing similar decisions.

Study of 5,388 repos finds AI-authored code merges faster at median, but 25% pay real review cost

A scan of 5,388 public repositories covering 444,225 merged pull requests found that the median repo experiences no extra review burden from AI-attributed code, with attributed work merging in roughly half the time of non-attributed work. However, the top quartile of repositories did show a measurable review cost, with time-to-merge running at least 1.18 times longer for AI-attributed pull requests. Attribution was determined strictly from commit-level markers such as co-author tags and agent bot accounts, not inferred from code style or timing. The researcher behind the study disclosed a commercial interest in the scanning tool used, while noting the findings actually work against a simpler sales narrative. Key caveats include that inline AI completions leave no repository trace, meaning detected figures represent a floor, and causation between agent use and review time cannot be established.
