💻 AI-ASSISTED CODING
The Good, The Bad, and The Ugly of AI-Assisted Software Development: What Engineering Leaders Need to Know About 2025 | 20 min read
When AI tools boosted dev team productivity by 10× and turned prompt-based coding into default workflow, many teams got faster, but now some end up with brittle, hard-to-maintain systems and “senior” engineers who can’t debug without AI
How I Turned Claude Code Into a War Machine (part 1) | 21 min read
A powered-up Claude Code can juggle five projects at once by combining 16 expert-agents, real-time verification tools, and a strict anti-hallucination protocol - turning AI “suggestions” into reliable, production-ready outputs
🏗️ ARCHITECTURE
Distributing big AI models in mobile apps | 15 min read
Small-footprint mobile apps can now ship powerful AI, but only if developers pick carefully between cloud-based models and on-device ones to balance privacy, storage, speed and convenience
A backend built with resiliency in mind, fallback caches, queue-backed writes, circuit breakers, telemetry, can keep operating even when your database or cache dies. Chaos-testing that setup proves those protections actually work under real stress
From Heroku to AWS: 11 lessons learned from migrating a data-intensive Rails application | 16 min read
A painfully honest look at what it really takes to move a heavy Rails app from Heroku to AWS - from database dumps to timed downtime windows, and 11 concrete lessons the team learned to pull it off as smoothly as possible
🤖 LLMS IN PRODUCTION
Accuracy of complex, multi-hop AI queries jumped from 43% to 91% when the team replaced traditional vector-search RAG with GraphRAG - cutting hallucinations and query cost by 97%
A clever rework of technical specs, turning dense multimedia docs into easy-to-digest visual and modular format so devs no longer dread reading specs
From PDF to Knowledge Graph: Fine-Tuning a Local Mixture of Experts with MLX and Obsidian | 8 min read
A DIY workflow that turns PDFs into a fully-linked knowledge graph, fine-tuning a small model on your laptop so academic papers become interconnected, searchable notes in Obsidian without ever leaving your device
Documentation is the only MCP security that scales | 15 min read
Clear, easy-to-find documentation is the only thing standing between a powerful protocol and widespread disaster, because Model Context Protocol (MCP) by default gives AI-tools root-level access, and only good documentation forces safe behavior
They show how a multimodal LLM judge can automatically assess thousands of charts, defining “good” across five dimensions and catching messy or misleading plots humans might miss
The article describes how two different retrieval-augmented systems: one based on semantic content, one on collaboration networks, can sift through hundreds of thousands of biomedical publications and pinpoint experts in seconds
A new tool shows how you can speak to AI and get fully working web apps in real time - voice-input, instant code generation, and live preview
Parlant: Can We Really “Guarantee” Agent Compliance? | 11 min read
They question whether Parlant, a framework promising guaranteed compliance of AI agents, can truly deliver reliability given the inherently probabilistic nature of LLMs
📊 DATA
Lakehouse tables don’t self-heal - frequent micro-batches and updates leave behind thousands of tiny files and metadata fragments. Without regular compaction, vacuum and metadata cleanup, queries can slowly grind to a crawl, this article shows exactly how to avoid that
Real-time pipelines don’t just “stream data” - this article digs into how a mix of Apache Flink, Airflow and StarRocks lets you ingest CDC data reliably: why they rejected some ingestion methods and what finally gave them “exactly-once” streaming with flexibility and performance
Elasticsearch Queries That Never Break in Production | 20 min read
String-based Elasticsearch queries can silently “succeed” but return empty or wrong results due to typos or type mismatches - SoftClient4ES solves that by catching such mistakes at compile-time rather than production time
⚙️ DEVOPS
Automated reviews of infrastructure-as-code just got a whole lot smarter, this article walks through how a custom reviewdog-action-checkov for Checkov turns every pull request into a fast security audit, catching misconfigurations like missing encryption before anything hits production
They slashed a CI/CD workflow from 40 min down to 13 min using data-driven profiling, caching, parallel deploys and faster bundling to unlock real developer velocity
🧮 DATA SCIENCE
Text-prompted diffusion models can now be built from scratch, learn how to train a full text-to-image network in PyTorch, step by step, with modular components and free-form prompts
Solving NYT Strands is a deceptively chill word-search - until you try to build a solver for it and realize it’s a linguistic combinatorial nightmare disguised in pastel graphics
Tired of unreadable “hairball” network graphs? This guide shows how to turn dense corporate-network messes into clean, insightful visuals that actually communicate structure
Hidden clusters in US power-plant data reveal surprising groupings, from “clean, high-capacity renewables” to “polluting backup generators used only at peak demand.”
Khmer Semantic Search Using Text Embeddings | 20 min read
Semantic search for Khmer just got smarter, this article shows how embedding models like LaBSE can map Khmer and English meaningfully into the same vector space so your queries find contextually relevant Khmer content, not just keyword matches
🟨 JAVASCRIPT
Frozen user-interface? The pain might not be your code, it’s when you ignore browser scheduling. Learn why idle-time awareness turns sluggish JS into silky-smooth apps
Angular pipes: Time to rethink | 11 min read
