Fine-Tuning vs RAG vs Prompt Engineering: Choosing the Right AI Strategy for Your Business

Companies today are integrating AI into customer support, analytics, automation, healthcare, finance, education, and enterprise applications. However, as organizations start building AI-powered solutions, one major question appears: “How do we m...

solSafe

I sell Solana token facts for two cents a call, and refuse to give an opinion While building this I ranked a token's trading pairs by pool depth, which seemed obviously correct. It picked JUP's biggest pool — quoted in an obscure token — and reported a price of $943 against a real price of about $0.19. A 5000x error that would have silently poisoned everything downstream. Depth doesn't make a de...

5 ATS blockers that kill LinkedIn Easy Apply (and how to fix them)

I built a free ATS resume checker after seeing too many friends get ghosted on Easy Apply. Most people think ATS means “add more keywords.” In practice, a lot of resumes fail earlier — on parsing. The 5 blockers I see most Columns / two-column layouts Nice for humans. Bad for many parsers. Contact info or skills in a sidebar often get read in the wrong order (or skipped). Fix: one-column layout...

8つの知覚軸で声をデザインする — 意味軸 話者埋め込みブレンド

📝 Originally published (in Japanese) at forge.workstyle.tech. 音声変換モデル（Voice Conversion）や TTS を触っていると、こんな壁に突き当たります。「目標の声は、参照音声（リファレンス）を1本まるごと渡して指定する」という前提です。でもプロダクトのユーザーが本当に言いたいのは、そういうことではありません。 「今の声を、もう少し若く、少しだけハスキーにしたい」 参照音声を差し替える操作では、この「もう少し」「少しだけ」が表現できません。声を連続的なつまみで微調整したいのに、モデルの入力は離散的な「誰かの声」なのです。 この記事では、その隙間を埋める汎用テクニックを紹介します。人間が理解できる知覚軸（若い↔年配、クリア↔ハスキーなど）のスライダー値から、複数の「アンカー話者」の埋め込みを加重合成して...

Cadence Over Volume — Orchestrating Multiple Projects with AI Agents

Running multiple projects in parallel with AI agents produces a counter-intuitive effect: without a compounding infrastructure, every run starts from zero. Memory stays local to the project, discovered patterns don't migrate, and cadence depends entirely on human availability. What follows describes the infrastructure that solves this problem — and why regularity is its primary condition. Three l...

Docker Images Without the Bloat

The Problem with Fat Images We've all been there: you pull an image, run docker images, and see a 1.2GB monster staring back at you. That's not just disk space wasted; it's slower pulls, slower deploys, and a larger attack surface. The usual suspects? Base images with unnecessary tools, build dependencies left behind, and layers that contain temp files or caches. I've been guilty of sh...

From Unsafe Terminals to Verified Agents: How Low-Level Rust, 6502 Retrocomputing, and LSP-Based Trust Are Reshaping Modern Developer Tooling

Originally published on tamiz.pro. The modern developer tooling landscape is undergoing a quiet but profound philosophical shift. For years, the dominant paradigm was abstraction-heavy: high-level languages, managed runtimes, and dynamic scripting environments that prioritized developer velocity over system predictability. Today, we are seeing a counter-movement driven by three distinct yet conve...

Knowledge-and-Memory-Management v0.0.2: Portable Knowledge Collection & Memory Management

The v0.0.2 release of Knowledge-and-Memory-Management is exactly what a clean release should look like: no leftover personal paths, no hardcoded /home/you/ dangling in the config, and a clear split between knowledge collection and memory management. If you've been following the 0.0.x line, this is the release where the tool finally becomes portable across machines and agents. Here's what changed a...

One API Key Across OpenAI, Claude and Gemini: Chatbot Fallback Options for SaaS Apps

Pick a chatbot gateway that exposes one chat API behind one key and lets you change models with a string — then keep the fallback ladder in your own code, where you can test it. That's the whole answer. Everything below is how I got there. I ship RAG and agent features in Python for a mid-size SaaS product, and our in-app chatbot has been through three routing designs in about eighteen months. T...

Claude Code hooks: why "just tell it not to" doesn't hold up

If you've spent time customizing Claude Code, you've probably written a line like this in your CLAUDE.md: "always run the formatter after editing a file" or "never touch .env or any .pem/.key file." It works — until a long session, a big diff, or a context window full of other instructions makes that one line easy to deprioritize. The model isn't being careless; a system prompt is advisory. Every ...

Human in the loop is not a switch: classify the commands

Human in the loop is usually implemented as a switch: approvals on, or approvals off. Both settings are wrong for an agent that runs shell commands, and you find that out the same way everyone does, which is by watching a long task die on its third ls. The stall looks like this. Your agent is working through something multi-step, it needs to look at a directory, the harness raises an approval, an...

I'm building an AI tutor with a talking professor avatar — here's what actually worked (and what flopped)

I've spent [X months] building COSMIQ (https://getcosmiq.app) — an AI tutoring platform for K-12 where lessons are taught by a talking avatar professor, "Dr. Lynch," on an interactive whiteboard. Kids answer questions on the board, the tutor grades in real time, and parents get progress reports. I'm not going to pitch it here. Instead, here's what I've learned that might save you time on your own...

Validar números de teléfono en JavaScript: por qué tu expresión regular está mal

Y lo peor es que falla en silencio — acepta basura y rechaza números perfectamente válidos de usuarios reales que se van sin registrarse. Te cuento por qué el problema es irresoluble con regex, qué es E.164, cómo usar libphonenumber-js sin los tres errores habituales, y qué columna ...

Best Simple Hosted API for a Node.js App Health Dashboard Without Prometheus

If you just want the recommendation: for a small startup building a basic hosted app health dashboard, choose a simple metrics-and-logs API when custom counters and gauges are enough; keep Prometheus or a fuller observability platform for alerting, tracing, and serious infrastructure diagnosis. Short answer: Infrai is a reasonable simple choice for pushing health-related custom metrics and search...

Jollof, Sunday Special — A Bowl of Jollof Rice in Pure CSS
