I rebuilt StrictBlock (my app) from the ground up. StrictBlock is an iPhone app blocker and focus app designed to help people stop procrastinating, protect deep work, and build better focus habits. For this relaunch, I did not want to just “refresh the UI.” I wanted to redesign the full product experience around one question: How can I make starting a focus session feel simple, strict, and useful? The new version focuses on reducing friction. Users can create focus profiles for study, work, sleep, deep work, or Pomodoro sessions, then start blocking distracting apps and websites with less setup. I also redesigned the app around accountability. StrictBlock now includes streaks, trophies, weekly reports, widgets, session journaling, and consequences for ending sessions early. As a developer, this redesign was a good reminder that productivity apps are not only about features. They are about behavior. The UI, the flow, the defaults, and the friction all shape whether someone actually stays focused. StrictBlock is now live with a complete redesign. Would love feedback from other builders, iOS devs, and product engineers. Try it here: Download strictblock on appstore

May 29 I wrote my first AI trainwreck story. June 18 I finished #15. People keep asking if this was...

Hey everyone, I wanted to share an open-source library I’ve been developing to solve a persistent issue in frontend file ingestion: handling large-file uploads efficiently without blocking the main thread, consuming excessive client-side memory, or introducing heavy npm dependencies. The core architecture leverages Fetch Duplex streams combined with Web Streams API to achieve constant memory usage during large file transfers. For browsers lacking full duplex stream support (such as Safari), it seamlessly switches to an automated chunked XHR fallback at runtime. ⚙️ Core Architecture & Features Constant Memory Footprint: Streams large chunks sequentially using Fetch duplex streaming where supported. Intelligent Runtime Fallback: Detects capabilities instantly and falls back to a robust, chunked XMLHttpRequest pipeline to ensure cross-browser compatibility (including Safari). Resilient Lifecycle Management: Built-in hooks for pause, resume, manual abort, and automated chunk-level retries with a configurable exponential backoff algorithm. Zero Dependencies & Tree-shakeable: Written entirely in vanilla TypeScript with no external runtime dependencies (npm install u/universal-uploader/core). The architecture is highly modular, ensuring that unused upload strategies are completely tree-shaken during compilation. React Primitive Included: Ships with a declarative React hook that maps the entire upload lifecycle to state primitives without causing redundant re-renders. 🛠️ Why Existing Solutions Didn't Fit Most mainstream uploading libraries either rely on heavy multi-part form encodings that require buffering files entirely into browser memory, or pull in heavy polyfill architectures that bloating the initial bundle size. I designed this to isolate the transport layer logic via a composition-based approach, separating the stream controller from the network client. To ensure deterministic behavior, the codebase is fully covered by 127 integration/unit tests validating network

FinOps X 2026 , terminó hace apenas una semana y concluyó con JR Storment, el Director Ejecutivo de la FinOps Foundation compartiendo uno de los anuncios más esperados, la presentación de Tokenomics Foundation . ¿Qué es? Es una iniciativa de la Linux Foundation, que busca establecer estándares abiertos, lineamientos referentes, y buenas prácticas de forma específica para el costo en Inteligencia Artificial y el uso de tokens, así como otros elementos relacionados con esta tecnología con el objetivo de guiar a las empresas y organizaciones a optimizar su consumo de IA y generar mejores resultados en el valor tecnológico. Algunas acciones: Visualización de los costos Atribución del valor Estandarización de procesos, entre ellos FOCUS La creación de esta iniciativa surge en un momento en el que la IA, se ha colocado como una de las tendencias más relevantes, desde LATAM y otras regiones, con diferentes niveles de desarrollo, y un nivel de diversidad complejo. De forma aparente el costo de la IA puede verse reflejado en los tokens, pero la realidad es que sólo es una parte de los que representa el costo de soluciones de IA, partiendo particularmente de la estructura de costos de estas tecnología, en lo global, podemos detectar 3: Costos del modelo : Engloban los costos del desarrollo e implementación del modelo Costos indirectos : Están relacionados con el funcionamiento de un modelo a nivel organizacional Costos asociados : Integran las erogaciones, relacionadas con las puesta en marcha del modelo, pero no directamente en él, por ejemplo, la infraestructura, y servicios relacionados Dentro de cada categoría de costos, los servicios y etapas del desarrollo de IA, son variados Los servicios y etapas de la creación de procesos de IA que están involucrados en cada categoría de costos, muestran la complejidad para la creación de valor en estas iniciativas. Durante FinOps X, tuvimos diferentes charlas relacionadas con IA, el principal reto: cómo monitorear, medir, e incremen

📖 Originally published on my blog . Part of a series on building with Claude Code. For a while I'd watch the AI work and quietly grumble: a fairly big task, and it would finish one module before starting the next, while I just sat there waiting for it to clear one before the other's turn came up. The work itself was fine—it was just slow. Slow because it was stuck in a queue. Then it clicked: a lot of these modules have nothing to do with each other, so why make them go one after another? Split them up, let several agents work at the same time, done. What I want, and where it stops What I want is simple: the same work, for roughly the same tokens, with the wall-clock time cut way down. But let me put the boundary up front— not every task can be split this way . This is just an approach I've worked out for myself; take what's useful. The prerequisite: a clean architecture For several agents to work at once without stepping on each other, the prerequisite isn't the AI—it's your architecture . That task of mine could be split because it was already several modules, talking to each other through interfaces, with internal implementations that don't affect one another—as long as each one honors the interface contract, it can be built independently. Loosely coupled, highly cohesive, in other words. And I'd nailed that design down together with opus before writing a line: opus helps me think it through and lays out options, but I'm the one who decides . You can't cut corners here. Forcing parallelism onto an architecture you haven't cleanly split is like cutting a tangle of yarn into a few pieces that are all still knotted together—it only gets messier. Who runs the show, who plans, who does the work With the design settled, it's time to assign roles. The split I tend to use: opus runs the show —holds the big picture, hands out work, does the final check; sonnet does the TDD planning —per the design, it lays out how each module gets tested and implemented; haiku writes the

AI Coding Agents Need a Control Layer AI coding agents are getting good enough that the problem is changing. A year ago, the question was mostly: Can this thing write useful code? Now, for a lot of builders, the better question is: How do I supervise this thing once it is actually doing work? That shift feels important. Claude Code, Cursor, Codex, and similar tools are not just autocomplete anymore. They can plan, edit files, run commands, review code, and work across larger chunks of a project. That is powerful. It also gets messy fast. The bottleneck is moving The hard part is no longer just picking the best coding agent. It is figuring out how to manage agent work once multiple tools or sessions are active. Questions start showing up: What is each agent doing right now? What changed? What still needs human review? Where did approval happen? Which agent owns which task? Did two agents touch the same part of the codebase? What should be paused, redirected, or stopped? What happened while I was focused somewhere else? That is not really a prompting problem. It is a control problem. The current workflow is mostly duct tape A lot of agent workflows seem to rely on some combination of: terminal tabs tmux sessions git branches git worktrees editor diffs notes issue trackers rules files memory vibes That works for a while. But once agents become more autonomous, or once a builder runs more than one agent at a time, the workflow starts to need a real operating layer around it. Not because the agents are bad. Because the agents are getting useful enough to need supervision. The missing layer The layer I keep thinking about has a few jobs. State What is running? What is paused? What needs attention? Ownership Which agent owns which task, branch, file, or objective? Review What changed, and what still needs a human to look at it? Approval Where should the human say yes before work continues? Intervention When should a builder pause, redirect, compare, or stop an agent? Memor

All tests run on an 8-year-old MacBook Air. All results from shipping 7 Mac apps as a solo developer. No sponsored opinion. I built Hiyoko PDF Vault — a macOS PDF tool — in Rust. Choosing the right PDF library was the first real decision. lopdf or pdfium. Here's what I found. lopdf: pure Rust, no dependencies lopdf is pure Rust. No C bindings, no system libraries, no bundling headaches. What it does well: Merge, split, rotate pages Read and write PDF structure Metadata manipulation Bates numbering Works well for structural PDF operations What it struggles with: Rendering PDFs to images (not its job) Complex font handling Malformed PDFs — lopdf is strict; real-world PDFs often aren't For a tool that manipulates PDF structure without rendering — merge, split, encrypt, add watermarks, strip metadata — lopdf is the right choice. Pure Rust means easy cross-compilation and universal binaries with no extra work. pdfium: full rendering, C dependency pdfium is Google's PDF engine (from Chromium). The pdfium-render crate wraps it for Rust. What it does well: Accurate PDF rendering to images Handles malformed PDFs that lopdf rejects Text extraction from complex layouts Full PDF spec compliance What it requires: Bundling the pdfium binary with your app (~20MB) Architecture-specific binaries (x86_64 and aarch64 for universal binary) More complex build setup For a tool that needs to display PDFs or extract text from complex documents, pdfium is the right choice. You pay for it in bundle size and build complexity. What I actually use lopdf for structural operations: merge, split, encrypt, watermark, metadata, Bates numbering. Apple Vision Framework (via Tauri shell commands) for OCR — it's already on the user's Mac and handles Japanese text better than anything I could bundle. I avoided pdfium because the bundle size increase wasn't worth it for my use case. If I needed accurate rendering, that calculation would change. The honest recommendation Start with lopdf. It covers most PD

I thought DEV Challenges were about winning. What participating in DEV Challenges taught me. A few months ago, I joined DEV. I didn't know many people. I wasn't well known. I simply wanted to become a better developer. Like many newcomers, I believed something very simple. "If I can win a challenge, maybe that means I'm becoming a real developer." So I kept participating. Sometimes I built retro games. Sometimes I experimented with AI. Sometimes I simply challenged myself to finish something before the deadline. Every challenge taught me something. Every badge made me smile. But after several months, I realized something unexpected. The biggest prize wasn't the badge. I started asking myself... What happens after the contest ends? The badge stays on my profile. The project goes to GitHub. Then... What's next? That question stayed with me for a long time. Then I realized something. I had been focusing on the contest. But the real value wasn't the contest. It was the community. Without DEV... I would never have discussed ideas with developers from around the world. I would never have received reactions from people I had admired. I would never have met developers with completely different ways of thinking. The challenge wasn't just building software. The challenge was becoming part of a community. Something I had rarely experienced before. Most communication happens inside companies. DEV felt different. It gave me a place to keep showing up. To keep learning. To keep improving. That matters more than I realized. The hardest part isn't building software. This surprised me. As I kept building apps, I realized something. Building an app is difficult. But building a place where people discover that app... is much harder. That's when I started appreciating communities like DEV even more. Someone had to build this place. Someone had to create a market where beginners and experienced developers could stand on the same stage. That's an incredible achievement. My goal changed.

A few weeks ago, I started exploring the Afriex MCP server. The setup was surprisingly straightforward. Connect your MCP client. Configure your API key. Verify the connection. Done. But then I ran into a different problem. Not a technical problem. A prompt problem. The Blank Prompt Problem Once everything was connected, I found myself staring at an empty prompt box. What should I ask? Sure, I could retrieve balances. I could create customers. I could generate virtual accounts. But what were the most useful workflows? What were the prompts that would actually help developers build real products? This isn't a problem unique to Afriex. It's becoming a common challenge across the entire MCP ecosystem. The infrastructure exists. The tools work. But many developers don't know where to start. MCP Changes How We Build Traditionally, integrating a payment API looked something like this: Read documentation Find the endpoint Write HTTP requests Parse responses Build business logic With MCP, the workflow looks very different. You can simply tell your AI assistant what you want to build. For example: Create a customer onboarding flow that: - Collects customer details - Generates a virtual account - Displays payment instructions Build it using Next.js and TypeScript. Instead of manually stitching everything together, the AI can interact with infrastructure through the MCP server. That's incredibly powerful. But only if you know what to ask. The Idea That's what led me to build the: Afriex MCP Prompt Cookbook A collection of practical, production-oriented prompts designed specifically for developers building with Afriex MCP. The goal is simple: Copy. Paste. Build. Instead of starting from scratch every time. The cookbook is open source and available on GitHub: https://github.com/SonOfUri/afriex-mcp-cookbook Feel free to explore the prompts, use them in your own projects, and contribute new recipes. What's Inside The cookbook is organized around real-world use cases. Not API endpoi

Originally published on MRTD.NET — fast, sourced news on crypto security, cyber & SEO. The uncomfortable first lesson You built a clean site, submitted a sitemap, maybe pinged IndexNow — and Google still shows nothing. Here's the part most guides skip: getting indexed by Google and getting indexed by everything else are two different problems , and conflating them wastes weeks. We separate what actually moves Google in 2026 from the folklore that just feels productive. Bing, Yandex and ChatGPT are the easy half If you've set up IndexNow , you've largely solved discovery for Bing, Yandex, Naver, Seznam and Yep — you POST your new/changed URLs to one endpoint and they get notified instantly. And because ChatGPT Search retrieves from Bing's index , confirmed Bing indexing effectively gates your visibility in ChatGPT's web results. That's a big chunk of the modern search surface handled with one integration. The catch: Google does not use IndexNow. It has said so repeatedly. So every "instant indexing" claim that leans on IndexNow is talking about Bing's world, not Google's. For Google, you need different levers. What actually gets you into Google There are really only two fast paths, plus one slow one. 1. Google Search Console — the only direct lever. Verify your domain (a private DNS TXT record; it does not trigger penalties or "re-evaluation," a common fear), submit your sitemap.xml , then use URL Inspection → Request Indexing on your key pages. There's a soft daily cap (~10–12 URLs), so spread a new site's pages over a few days. GSC is also the only place you can see whether a domain carries an inherited problem — essential if you bought an aged or expired domain. 2. Links on pages Google already re-crawls hourly. Googlebot's crawl budget for a brand-new, zero-authority domain is tiny. The fastest way to get a new URL discovered is a link to it from a page Google visits constantly — Reddit, Hacker News, Medium, established communities. These links are usually nofoll

AI Agent 的记忆系统通常只解决一个问题：「记住」。gbrain 存知识图谱，Hindsight 存向量，Memory tool 存偏好。三个仓库堆满数据，但你问 Agent「我上周看的那篇关于 Agent memory 的文章说了什么？」——它答不上来。不是因为记不住，是因为它的记忆系统没有「采集」这一层。 这就是 Knowledge-and-Memory-Management（KMM）的定位：不是另一个记忆数据库，而是一个 知识采集 → 精炼 → 召回 → 同步 的全链路插件。v0.0.2 把这条链路做完了。 架构思路：把「采集」和「记忆」解耦 KMM 不做记忆存储，它只做三件事： 采集 — 从 40+ 工具把原始知识拉进来 精炼 — 把原始材料变成结构化笔记 + 知识图谱节点 同步 — 写 OneDrive，让所有设备共享同一个知识池 下方是三层采集管线示意： 层 工具数 代表工具 网页 9 Scrapling (CF 绕过)、Chrome DevTools Protocol、GStack Browser 视频 12 抖音批量转录、yt-dlp、Whisper ASR (99 语种) 文档 9 SenseNova PDF/PPT/Word 引擎、MinerU、book_cache (710+ 本) 3 层召回：不让任何一条知识掉队 搜索时先查本地 FTS5（毫秒级），没命中就走 Hindsight 向量（语义近似），再不中就落 gbrain 知识图谱（关联推理）。三层兜底，基本不存在「查不到」的情况。 代码片段：rclone 做云盘双向同步 KMM 的 CloudSyncEngine 不造轮子，直接用 rclone 做统一同步层。核心代码很直白： class CloudSyncEngine : def __init__ ( self ): self . _check_rclone () def _check_rclone ( self ): result = subprocess . run ([ " rclone " , " version " ], capture_output = True , text = True ) if result . returncode != 0 : raise RuntimeError ( " rclone not installed " ) def bidirectional_sync ( self , local_path , remote_path ): """ 双向增量同步，每 4h 自动执行 """ cmd = [ " rclone " , " bisync " , local_path , remote_path , " --resync " ] return subprocess . run ( cmd ) 这没什么黑科技，关键是架构决策：用 rclone 支持 12+ 云盘（OneDrive / 阿里云盘 / 百度云盘 / Dropbox / Mega / 天翼云等），不需要为每个云盘写专属 SDK。一份配置，双向同步，cron 每 4 小时自动执行。 一个完整的采集流 用户丢过来一个抖音视频链接 → collect_video() 自动走三条线并行： yt-dlp 下音频 → Whisper ASR 转文字 → PaddleOCR/EasyOCR 提关键帧文字 。输出汇总后 → generate_note() 写结构化笔记 → create_note() 入 gbrain 知识图谱 → sync_to_cloud() 推 OneDrive。全自动，零人工参与。 踩过的坑 不要用 Python 重写云盘同步 。KMM v0.0.1 试过直接调各云盘 REST API，token 刷新、分片上传、断点续传全要自己处理，维护成本极高。v0.0.2 切到 rclone bisync 后问题归零。 视频分析不只看语音 。抖音很多技术号用字幕 + PPT 画面讲内容，语音只占信息量的 60%。必须 OCR 做画面补充，否则丢失大量知识。 去重不做在采集层 。采集层只管拉，去重交给 gbrain 的 content_hash 和 nightly_maintenance 的 orphan compaction，职责分离更干净。 适用场景 如果你的 AI Agent 已经跑了一段时间，积累了几千条笔记 / 几百个知识图谱节点，但你还是觉得「它好像什么都不懂」——问题很可能出在知识摄入链路上。KMM 适合你已经有一套记忆系统，缺的是一个自动化的知识采集和同步层。 仓库： github.com/mage0535/Knowledge-and-Management ，MIT 协议，PR

GitHub added a tiny field to the Copilot usage metrics API this week that is going to create a lot of very confident spreadsheets. Enterprise and organization admins can now see ai_credits_used in the user-level Copilot usage reports. One field. Per user. Available for single-day and 28-day reports. It is not the invoice, and GitHub is careful to say it is a consumption signal rather than a billed total. Still, the shape is obvious. Now AI usage can sit next to adoption, activity, team, department, cost center, and whatever else the company already exports into a dashboard. That is useful. It is also exactly how a tool metric becomes a management metric. And once that happens, the question is no longer "can we measure AI usage?" The question is "what weird behavior will this metric create?" every useful metric becomes a temptation I understand why this field exists. If a company is paying for Copilot, especially with usage-based pieces attached to more expensive models and premium features, it needs some way to understand consumption. Platform teams need budget signals. Engineering leaders need adoption signals. Procurement needs something more concrete than "people seem to like it." Finance will eventually ask why one org burns through credits much faster than another. That is normal. The problem starts when a consumption signal is treated as a productivity signal. High AI credit usage might mean a developer is doing valuable work with agent mode, code review, test generation, refactoring, or research. It might also mean the developer is stuck, repeatedly asking the model to solve the wrong problem, generating code that gets deleted, or using a heavyweight model where a small one would have been fine. Low AI credit usage might mean a developer does not need much help. It might mean the work is mostly design, review, debugging, incident response, mentoring, or architecture. It might mean the codebase is small and well understood. It might mean the developer is skept

As software engineers, we often architect solutions in a virtual ideal: fast networks, elastic resources, and servers that never physically degrade. But what happens when your carefully crafted systems need to interact with the messy, unpredictable physical world? Think factory floor monitors, real estate camera networks, or remote tracking devices. Suddenly, those cloud assumptions about infinite uptime and perfect connectivity crumble. My journey, particularly architecting and maintaining a continuous 24/7 camera livestream for a real estate group over six years, has been a masterclass in this reality. It's revealed that true reliability in the physical realm demands a hybrid approach – one that intelligently merges the power of edge computing with the scalability and data insights of the cloud. This isn't just about connecting devices; it's about building resilience into the very fabric of your architecture. In this article, I'll share the battle-tested strategies and design principles that enable systems to not just survive, but thrive, despite the harsh realities of physical deployment. 1. The Core Strategy: Smart Edge, Simple Cloud One of the most common pitfalls in hybrid architecture design is treating the edge device as a mere 'dumb' terminal, solely responsible for streaming raw data to a powerful cloud backend. This approach creates a critical single point of failure: if the network drops, the entire system grinds to a halt. Instead, I advocate for a Smart Edge, Simple Cloud architecture. This principle establishes a clear division of responsibility: The Edge : This is where the magic happens locally. The edge system should be robust enough to handle local processing , data filtering , buffering , and immediate hardware control . Critically, it must be capable of operating autonomously for extended periods without an active cloud connection. Think of it as a mini data center, designed for self-sufficiency. Benefits of a Smart Edge : Reduced bandwidth cost

I've wanted easy trunk-based development for Salesforce for years. Short-lived branches, frequent merges, small pull requests, and CI fast enough that developers aren't afraid to commit. The same practices that engineering teams use everywhere else. Every time I tried to make it work, I hit the same wall: Apex tests require an org. That single dependency turns every validation run into an infrastructure problem. Before a test can execute, you need authentication, environment provisioning, metadata deployment, test execution, and cleanup. The result is feedback loops measured in minutes instead of seconds. I got tired of waiting and built Nimbus, a local Apex runtime that executes Apex tests without an org. This is what I learned while trying to make trunk-based development actually work for Salesforce. Why trunk-based development is hard in Salesforce Trunk-based development depends on fast feedback. If validation takes seconds, developers make smaller changes, merge more frequently, and keep branches short-lived. If validation takes fifteen minutes, behavior changes. Pull requests get larger, unrelated work gets batched together, and validation stops happening continuously because validation itself becomes expensive. Salesforce has always had a structural challenge here because Apex only runs inside Salesforce. A typical validation pipeline looks something like this: sf org login jwt sf org create scratch sf project deploy start sf apex run test sf org delete scratch There is nothing inherently wrong with these steps. The problem is that most of them have nothing to do with testing. They're infrastructure management. The actual validation of business logic is only one part of the process. The longer I worked with Salesforce CI, the more obvious it became that the bottleneck wasn't Apex itself. The bottleneck was everything required to create an environment where Apex could run. The solutions I tried first Before building a local runtime, I tried solving the problem

There is a class of feature that used to be impossible to ship for free: anything that needed a language model. You wired up an API key, you ate the per-token bill, and every prompt your users typed went off to someone else's server. For a small public tool, that math usually killed the idea before it started. That changed. Recent versions of Chrome ship a language model, Gemini Nano, and expose it to any web page through the Prompt API . The model runs on the user's own machine. No API key. No inference bill. No data leaving the browser. We put this into a real, live tool, a free Mermaid diagram editor where you describe a diagram in plain English and the browser writes the Mermaid code for you. This post is the developer's version of that story: how the API actually works, the code that makes a small on-device model trustworthy, and an honest accounting of what you gain and what you give up. What "AI in the browser" means in 2026 The important word is built-in . This is not WebGPU plus a 4 GB model you download and run yourself. The model ships with Chrome, and you talk to it through a small standard-track JavaScript API. As of Chrome 148, the Prompt API is stable for web pages (it had been available to extensions since Chrome 138). It is the general-purpose member of a growing family of built-in APIs: Prompt API ( LanguageModel ): general natural-language prompting, now multimodal (text, plus image and audio input). Summarizer, Writer, Rewriter, Proofreader : task-specific, text-to-text. Translator and Language Detector : backed by expert models, desktop only. The Prompt API is the one you reach for when you need something the task APIs don't cover, like "turn this description into Mermaid source." So that is the one this post focuses on. The 15-line version Here is the whole happy path. Check availability, create a session, prompt it. // Feature-detect first. Old browsers won't have this at all. if ( ' LanguageModel ' in self ) { const status = await LanguageMod

I run a homelab with four RTX 3090s — 96 GB of VRAM, 44 CPU cores. For two weeks I tried to make it my daily driver for local LLM inference instead of paying for cloud APIs. I got it working. Then I looked at the numbers and subscribed to a paid API anyway. Here's the uncomfortable part, and the optimizations that still made it worth doing. ## The setup 4× RTX 3090 (Ampere — no native BF16), 96 GB VRAM total, 44 cores Models: Qwen3.6-35B-A3B (Q8_0, MoE) and Qwen3-Coder-Next (Q6_K, hybrid) llama.cpp in router mode + OpenWebUI Ceiling I hit: ~105 tokens/second ## The 6% problem The wall wasn't compute. GPU utilization sat at 6%. The bottleneck was CPU orchestration — llama.cpp dispatches across multiple GPUs sequentially, so the cards spent 94% of the time idle waiting on each other. Throwing more VRAM at it does nothing for this. ## What actually moved the needle | Change | Effect | |---|---| | --ubatch-size 512 | +40% throughput | | KV cache quantization (Q4_0) | 4× VRAM savings | | Speculative decoding (n-gram) | 2.5× speedup on repetitive tasks | | YaRN rope scaling | context extended to 1M tokens | Two things surprised me: MoE models tolerate aggressive quantization far better than dense ones — inactive experts don't eat bandwidth, so the quant hit lands softer. The 3B active -parameter model was great at local decisions but fell apart on coherence past ~300–400 lines of code — fine for a function, not for cross-file consistency. ## The conclusion I didn't want At ~11 kWh/day, plus hardware depreciation, against current API pricing, the math doesn't favor local for interactive work. The single biggest improvement to my daily AI workflow was paying for an API. Local still wins for privacy, high-volume batch jobs, or uncensored experimentation — but not as a general cloud replacement. It's an economics problem, not a capability one. I wrote up the full cost breakdown and the exact llama.cpp router configs on aipster.com . If you're weighing a local rig, I also benc

For 13 years I have worked in production at a steel-tube manufacturer. Not in an office — on the floor, with the machines, the night shifts, the handovers at 6 a.m. A few years ago I started building software in my free time. Not tutorials for their own sake — tools that solve problems I actually see every day. Why a factory worker writes code In production you learn one thing fast: it does not matter what looks good on a slide. It matters what works at shift handover. That perspective turned out to be my biggest advantage as a self-taught developer — I know the problem before I write the first line. What I have built PIPEZ — a shift & part-count PWA. Offline-capable, running on Cloudflare Workers + D1, live in production to capture shift and piece-count data that used to live on paper. A tool-management app. A multi-user client-server app with optimistic concurrency and a local AI assistant, used daily in the office to manage the lifecycle of dies in tube production. DeepCode — an agentic AI coding client. Electron + React + TypeScript, with its own tool loop, a swarm mode, and CI/tests. The project I am proudest of. Plus multi-agent systems, RAG pipelines, and n8n automations that run every day. The stack Python/FastAPI, TypeScript/React, Node, Docker, PostgreSQL + pgvector, Cloudflare Workers, MCP, computer vision. Writing in public I will be writing here about the bridge I keep coming back to: real production experience plus building with AI. If you are automating something messy and real, I would love to compare notes.
