Developer Builds Hacker Terminal Simulator with Pure HTML, CSS, and Vanilla JS

·1 views

A developer on Day 98 of a 100-day full-stack engineering challenge built an interactive hacker terminal simulator using no external frameworks. The project relies solely on HTML, CSS, and Vanilla JavaScript to replicate realistic terminal animations and sequential text execution. Core mechanics include a custom async pacing function using native JS promises and setTimeout to simulate processing delays, alongside setInterval loops that animate loading indicators. The terminal sequence concludes with a final status message reading 'You are Hacked,' rendered without freezing the browser's main UI thread. The developer plans to spend Day 99 designing advanced component interfaces before a final production presentation on Day 100.

PostgreSQL Replans Prepared Statements When Planner Settings Change at EXECUTE

PostgreSQL offers planner configuration parameters like enable_seqscan and enable_indexscan that shape how query execution plans are generated, not how already-planned queries run. A key question arises with prepared statements: do these settings take effect at PREPARE time, at EXECUTE time, or both? Testing with a simple tasks table and a partial index shows that when enable_indexscan is turned off before EXECUTE, PostgreSQL generates a new plan using a sequential scan instead of the previously chosen index scan. This means planner settings applied before EXECUTE can trigger replanning, overriding the plan cached at PREPARE time. Developers should be aware that changing planner parameters between prepare and execute can significantly alter query behavior and performance.

Dev builds internal-linking system to help new tool pages rank on Google

A solo developer building an image-processing tool in public documented week 17 of their project, focusing not on new features but on SEO infrastructure. After shipping an AI background remover the previous week, they discovered the new tool's pages were orphaned — reachable via sitemap but not linked from anywhere on the site. To fix this, they replaced scattered hardcoded link lists with a single source-of-truth constant that automatically cross-links a hub page and its use-case spoke pages. The same constant also drives layout logic and populates a footer column, meaning any future spoke page requires just one line of code to be fully integrated. A React hydration error caused by invalid HTML nesting was also caught and resolved during the process.

How to Add Security Guardrails to Python LLM Apps Against Prompt Injection

A technical guide published on DEV Community outlines key security boundaries in large language model (LLM) applications built with Python. The article identifies three entry points for untrusted text: user input, retrieved content from RAG pipelines, and model output that feeds into further processing. It focuses on defending against prompt injection attacks, where malicious text attempts to override a model's instructions, by keeping user input in clearly delimited data channels separate from system instructions. The guide also covers input validation, output validation, and PII redaction as part of a broader 'security-forward' approach to LLM app development. Code examples using Anthropic's API illustrate the difference between unsafe string concatenation and safer, delimiter-based prompt construction.
