Tutorial: Screen SEC insider buying data using Python and a free API

·6 views

A developer tutorial published on DEV Community demonstrates how to build a Python-based insider-buying screener using SEC Form 4 data via the AlphAI API. The script accepts a watchlist of tickers and a dollar threshold, then outputs a Markdown table and CSV file showing insider purchase transactions within a 30-day window. Testing the tool against 25 well-known tickers between August 20 and September 18, 2026, returned no qualifying purchase events, while a separate feed of recent insider activity surfaced 11 purchases across seven smaller tickers. Key transaction details such as dollar value, stake change percentage, and director status are pulled from the API and kept alongside each purchase for context. The script requires Python 3.10 or newer with no additional dependencies, and the repository includes saved sample runs that can be reproduced without an API key.

How a Hidden BOM Character in PowerShell Broke API Auth for an Hour

A development team's automated deploy tool successfully pushed an API token to production, but every subsequent API request failed due to a Unicode byte-order mark (U+FEFF) being silently prepended to the token. The BOM originated from Windows PowerShell 5.1's default UTF-8 console encoding with a 3-byte preamble, which was injected when piping the secret to the platform CLI. Diagnosing the issue was significantly delayed because the platform's secret store marked the variable as Sensitive and write-only, making it impossible to read back and inspect through the dashboard, CLI, or API. Commonly cited fixes such as setting $OutputEncoding or [Console]::OutputEncoding were tested and found ineffective in this case. The team ultimately resolved the issue by bypassing the pipe entirely, writing the secret to a temporary file using explicit BOM-free UTF-8 encoding and redirecting that file to the process's standard input.

LimeWire's Tech Column Critiques Cloud Centralization and AI Liability Gaps

The revived LimeWire brand has published the second issue of its editorial column, C:\LimeWire\Shared, presenting a sweeping critique of modern cloud infrastructure and artificial intelligence practices. The piece argues that despite the illusion of a decentralized internet, over 90% of global web traffic is funneled through just four providers: AWS, Azure, Google Cloud, and Cloudflare. It also challenges the 'human-in-the-loop' design pattern in autonomous AI systems, contending that human oversight is often inserted not for safety but to shield corporations from legal liability. Drawing on literary references from Jorge Luis Borges, Harry Harrison, and cultural theorists, the column blends provocative writing with substantive systems architecture arguments. The publication follows the column's first viral issue, which focused on reported Microsoft and OpenAI data-scraping practices.

What a Virtual CISO Does and When Your Company Actually Needs One

A Virtual CISO (vCISO) provides part-time or contract-based senior cybersecurity leadership — covering strategy, compliance, and board communication — at a fraction of a full-time executive's cost. The model is most relevant for companies with 50 to 500 employees that have outgrown self-managed security but cannot yet justify a $350,000-plus hire. Common triggers for engaging a vCISO include enterprise customer security audits, investor accountability questions, uncoordinated incident responses, or rapid growth in regulated industries like fintech or healthtech. Unlike a full-time CISO, a vCISO focuses on leadership and strategy rather than day-to-day execution, typically owning compliance programs, security roadmaps, and incident response planning. The arrangement is designed to close the gap between ad hoc internal security and dedicated executive oversight without the associated executive overhead.

25 Prompt Templates to Help Developers Write Better AI Instructions

A curated list of 25 prompt templates aimed at developers was published on DEV Community on September 17, 2026. The templates follow a five-part structure and are largely adapted from Anthropic's public prompt library for Claude Code users. Eight of the prompts focus on speeding up coding tasks, covering areas such as codebase overviews, refactoring plans, test writing, and debugging. Each template includes an explanation of why it works, written in the editors' own words rather than copied directly from Anthropic. The collection is intended as a practical reference for developers looking to get more reliable and structured outputs from AI coding assistants.
