Developer Publishes SQL Cheat Sheet Covering Core Commands for Quick Reference

0
·2 views

A developer returning to programming after a lengthy break has published a SQL cheat sheet on DEV Community intended as both a personal review tool and a future reference guide. The article is structured in three parts and covers foundational SQL concepts, including how data is organized into tables, rows, and columns. Key SQL statements explained include SELECT, SELECT DISTINCT, WHERE, ORDER BY, INSERT INTO, DELETE, and UPDATE, each accompanied by syntax and practical examples. The guide also highlights important rules, such as ending statements with semicolons and the case-insensitivity of SQL keywords. The resource is aimed at readers who want a concise refresher on essential SQL operations within a few minutes of reading.

React Native Developers Are the New Target: A Guide to Securing Your Own Machine

A detailed security guide highlights that React Native developers themselves—not just end users—have become the primary targets of supply chain attacks. The guide warns that routine commands like yarn install execute untrusted code with full user privileges, capable of accessing SSH keys, keychains, and environment files without any sandboxing. Configuration files such as metro.config.js, Podfile, and build.gradle are actually executable programs that run automatically on build or project open, creating silent attack surfaces. Real-world incidents like nx/s1ngularity, Shai-Hulud, and GlassWorm demonstrate that these threats are active, with one attack hiding malicious payloads in invisible Unicode characters that evaded code review entirely. The guide also flags AI agent MCP servers as an emerging risk, with over 30% found to carry exploitable vulnerabilities that have already been used to steal private SSH keys.

Hermes Agent Builds Persistent Skills to Cut Costs for Long-Running AI Tasks

Nous Research released Hermes Agent in February 2026 as an open-source MIT-licensed runtime designed to address a core weakness in AI agent frameworks: the inability to retain and reuse knowledge across sessions. Unlike conventional frameworks that discard reasoning after each task, Hermes logs decision points and tool calls, then enters a reflective phase to assess what worked and convert successful approaches into structured 'skill documents.' These documents are indexed using SQLite FTS5, allowing future similar tasks to query the skill library before invoking the model, with community benchmarks showing up to 40 percent speed gains after around 50 accumulated skills. The architecture is built on five pillars — memory, skills, a persistent behavioral config called 'Soul', scheduled cron jobs, and a self-improvement meta-layer — all designed to compound efficiency over time. Deployment options range from a $59/month managed service to self-hosted builds costing as little as $6–$9 per month, with local inference on an 8B model reportedly achieving 91 percent tool call accuracy on just 8GB of VRAM.
