Developer Uses AI Agents to Automate Niche Newsletter Earning $500 Monthly

·2 views

A developer has built a largely automated newsletter targeting DevOps engineers focused on AWS cost optimization, generating around $500 per month while requiring only about 20 minutes of weekly review. The system uses Make.com workflows combined with GPT-4o to research trending stories via RSS feeds, draft content, and inject affiliate links automatically. Completed newsletters are pushed directly to the Beehiiv platform via its REST API, where the author does a final check before scheduling. Revenue comes from two sources: roughly $320 from newsletter sponsorships secured through platforms like Sponsy, and $180 from contextual affiliate links. The entire pipeline runs on three Make.com scenarios, one Airtable base, and two OpenAI API calls, costing under $4 per month in API fees.

How to Run Local LLMs Privately Using Ollama and Spring AI

Developers can run large language models (LLMs) locally on their own machines using Ollama integrated with Spring AI and Spring Boot, eliminating the need to send data to cloud providers like OpenAI or Anthropic. This approach is particularly useful for building AI applications without API costs, working offline, and keeping sensitive company data within internal infrastructure. Ollama supports several open-source models including Llama, Qwen, Gemma, Mistral, and DeepSeek, and exposes a local API that Spring AI can communicate with directly. A practical use case demonstrated is an internal HR customer support assistant where employee queries are handled entirely on-premise. Developers are cautioned that running an LLM locally does not replace the need for proper authentication, authorization, and data security measures.

Developer Details 5 Real-World Failures When Self-Hosting Chatwoot at Scale

A developer running self-hosted Chatwoot for around a dozen small Israeli businesses documented five production failures not covered in the official documentation. One major issue was that media attachments are stored in Docker volumes via ActiveStorage rather than in the PostgreSQL database, causing disk usage to spike undetected by standard database monitoring. The operator also found that duplicate media files — some stored up to 325 times — were consuming significant disk space, and a deduplication pass reclaimed over 3 GB across more than 7,000 blobs. A third failure involved the POST /messages API returning a 200 status immediately upon row insertion, before actual delivery to WhatsApp via Meta, causing a Sidekiq job queue to back up with over 3,700 jobs and nearly 11 minutes of latency during a resend loop. The account was handling several thousand conversations per week across two servers, with a custom drip-sequence engine contributing to several of the edge-case failures described.

Seven-Step Framework for Structuring IoT Test Automation Effectively

IoT testing is complex because connected products rely on hardware, firmware, networks, cloud services, and applications functioning in unison. A seven-step automation framework recommends starting by mapping device hardware revisions, firmware versions, and network conditions to define the full test environment. Teams are advised to prioritize stable, repeatable interfaces like APIs and protocol validation before automating more complex scenarios, while keeping some manual checks for physical setup. The framework emphasizes combining device simulators for scale with real hardware for physical validation, and integrating the entire test pipeline into CI/CD workflows so tests run automatically with each development change. Field failures should continuously feed back into the test suite, ensuring that resolved issues are covered by automation and are less likely to recur.

Why Self-Correcting Agent Loops Are Essential for Reliable AI in Production

Large language models (LLMs) deployed in production environments are structurally prone to hallucination, meaning they generate plausible-sounding but factually incorrect outputs with no internal mechanism to flag uncertainty. This is not a prompt engineering flaw or pipeline bug — it is an inherent property of next-token prediction systems that conflate plausibility with truth. Researchers warn that fine-tuning and prompt optimization alone cannot eliminate this fundamental uncertainty, yet companies continue integrating LLMs into high-stakes customer, financial, and legal workflows. A proposed solution called the COPS framework — Self-Correcting Production Systems — treats the LLM as one component in a multi-step pipeline that includes verification, criticism, and re-generation loops rather than a standalone answer authority. Experts argue that meaningful human oversight in high-stakes decisions, combined with these self-correcting architectures, represents the only viable path to trustworthy production AI systems.
