I built a zero-knowledge secret sharing tool. Text and files are encrypted in the browser with AES-GCM 256 before upload - the server only ever sees ciphertext. The decryption key lives exclusively in the URL fragment (#k=...). URL fragments are never sent in HTTP requests (RFC 9110 §4.2.3), so Cloudflare Workers, D1, and R2 never see it - even in logs. A few things I tried to do right: Single-use by default: Durable Objects handle atomic read→decrement→delete with blockConcurrencyWhile, no race conditions on concurrent requests Paranoid mode: returns not_found instead of expired/burned, no timing oracle Revoke endpoint: delete a drop before it's read using a SHA-256'd token with constant-time comparison CLI: burnafter send / burnafter receive - full E2E from terminal, key never touches a browser - /security page with a live in-browser AES-GCM demo and a manual Node.js decryption snippet so you can verify without trusting me Stack: Cloudflare Workers + D1 + R2 + Durable Objects. No third-party crypto libs. Live: https://burnafterread.casablanque.com Source: https://github.com/casablanque-code/burnafterread Verify: https://burnafterread.casablanque.com/security

A static-analysis approach to unifying 46 repositories (37 air-closet-side + 9 mall-side) of legacy production code into one knowledge graph. Why simply 'letting AI read the code' isn't enough, why I had to chase down boundary nodes (API endpoints, DB tables, Event topics), how I dealt with framework and library diversity, and what 3 months of trial and error solved or didn't solve — looking back through actual git history.

Organizing notes by topic sounds logical until you have notes on PostgreSQL in five different folders and cannot find the one that matters for today's problem. The issue is not discipline. The issue is that topic-based organization asks the wrong question. "What is this about?" is useful for libraries. For engineers, the better question is "What am I doing with this?" That is the premise of PARA. PARA is a simple four-bucket system created by Tiago Forte as the organizational backbone of his Building a Second Brain framework. The idea is that all information can be sorted into four categories: Projects, Areas, Resources, and Archives. Each category represents a different level of actionability, and that distinction drives where every note lives. This guide applies PARA to engineering work specifically — codebases, documentation, learning material, and the tension between active project work and long-term reference. The Problem With Topic-Based Organization Most engineers organize knowledge the way they organize code: by domain. databases/ postgresql/ redis/ api/ rest/ graphql/ devops/ kubernetes/ terraform/ That structure makes sense when you are browsing. It breaks down when you need something for a specific task. You remember a useful note about database migration safety, but it could be in databases/postgresql/ , devops/deployments/ , api/versioning/ , or nowhere because you saved it somewhere temporary. Topic folders force you to decide where knowledge belongs before you understand its context. PARA delays that decision — instead of asking what something is about, it asks what you are currently doing with it. The Four Buckets Projects A project is active, time-bound work with a defined outcome. For engineers, projects are things like: Migrate billing service to queue v2 Upgrade PostgreSQL from 14 to 16 Write architecture decision record for auth service redesign Implement rate limiting on public API Publish article about distributed tracing Every project has a c

Google Open Knowledge Format: Why Enterprise Agents Need a Knowledge Layer, Not Just More Tools Most enterprise AI conversations still start in the wrong place. They start with the model. Which model should we use? Which framework should we adopt? Which vendor has the best agent platform? Which tools should we connect next? These are fair questions. But in real enterprise architecture, they are not the hardest questions. The harder question is this: Can our AI systems actually understand how our business works? That is why Google Cloud’s article on Open Knowledge Format caught my attention. The article talks about a simple but important idea: representing knowledge in a way that humans can read and machines can use. In OKF, that means markdown for the content and structured metadata for context. At first glance, that may sound too simple. But that simplicity is the point. Enterprises do not need another place where knowledge goes to die. We already have enough portals, catalogs, wikis, dashboards, folders, and internal tools. What we need is a practical way to package knowledge so it can be reviewed, versioned, governed, searched, and reused by both people and AI agents. That is where this idea becomes very relevant for agentic AI. The Real Enterprise AI Problem Most organizations already have the knowledge their AI agents need. They have it in databases, dashboards, tickets, architecture notes, runbooks, Confluence pages, data catalogs, code comments, incident reports, old project documents, and the heads of experienced employees. The issue is not that knowledge does not exist. The issue is that it is fragmented. Some of it is outdated. Some of it is duplicated. Some of it is tribal. Some of it is locked inside tools. Some of it is written for humans but not structured enough for AI systems to use reliably. This becomes a serious problem when we move from AI assistants to AI agents. An assistant can give a helpful answer. An agent does more. It plans, selects tools

By spring 2026, the division of labor between human engineers and AI had become precise enough to describe. Not speculate about. Describe. Delegate these 7 immediately: Boilerplate generation: CRUD scaffolding, config files, standard patterns. Near-human accuracy. Review required is a naming scan, not a logic audit. Test generation: 40-60% faster test development with no measurable decline in coverage quality, provided the tests are reviewed by someone who understands the domain. Documentation: 67% of companies rely on AI-assisted doc generation in 2026. The first draft is a solved problem. Your job is verifying and contextualizing. Code translation: Python to TypeScript. React to Vue. Framework migrations that once consumed sprint cycles now take hours. Routine bug fixing: Claude Code, Devin, BugBot can resolve 60% of reported bugs autonomously. Resolution time down 30-50%. Automated code review: First-pass filter before human review. Misses context issues. Doesn't replace human review. Eliminates noise so you focus on signal. Commit hygiene: Messages, PR summaries, changelog entries. Fully automatable. No meaningful error rate. Never delegate these 6: Architecture and system design: AI proposes. You decide. The tradeoffs require organizational context, team capability assessment, and long-horizon thinking no model possesses. Business context translation: The spec says "export to CSV." You ask: which users, under what conditions, with what compliance implications? AI cannot know the specification is wrong. You can. Security architecture: AI generates vulnerabilities as readily as it detects them. Adversarial thinking is not statistical. It is human. Long-horizon product thinking: What to build and why. Not how. Multi-stakeholder navigation: The politics, the relationships, the conversation with the PM that keeps the sprint on track. No model has stakes in the outcome. Agent orchestration: Designing, managing, and correcting the AI systems themselves. This is the ne

Obsidian prompts beat open-ended reflection every time: median review time across 6 weeks was 14 minutes, fastest was 9, slowest was 22 (and that week genuinely deserved 22). I ran the GTD-adjacent version faithfully for six weeks — 90 minutes, full capture sweep, energy audit, the works. Then less faithfully for two months. Then I stopped entirely and didn't notice for three weeks. That last part is the failure mode nobody writes about. The format wasn't wrong; it was sized for a version of my week that rarely existed. The fix wasn't a better framework. It was shorter, closed questions. My Obsidian template has seven prompts, none of them open-ended: what shipped, what didn't, what I avoided and why, one thing to drop, one thing to protect. One-to-three sentence answer ceiling per prompt, hard stop. Open questions like "how was your week?" generate rumination. Closed questions generate decisions. That distinction is doing almost all the work. The Notion version I ran before this taught me something useful about tool selection too. I built rollups — tasks closed this week, open tasks by project, inbox count, stalled for 7+ days — and they worked exactly as designed. What Notion couldn't do was get out of its own way during actual reflection. Every time I tried to think through what went wrong, I'd end up reorganizing a database instead. Forty minutes later, new linked database, zero review completed. The same flexibility that makes Notion a good data layer makes it a bad "close the loop and move on" environment. Obsidian's plain-file simplicity is the right call for the thinking layer — and completely wrong for the data layer. Neither tool alone is the honest answer. There's also a cautionary note from my automation setup: a Zapier zap that pushed completed tasks into Notion for weekly rollup ran cleanly for two months, then silently broke when my task manager updated their API response format. Modified tasks started logging as completed. My rollup became noise befo

I built a knowledge graph out of my own work sessions. Hundreds of them — transcripts of me building a system with LLMs, extracted into concepts, decisions, findings, and the edges between them. For a while it felt like the thing was working. I'd query it, get back a clean structured answer, and move on. Then I ran a foreign model against it. I gave a different model my concept definitions and asked it to reconstruct the system, both the vocabulary and the relationships. It recovered 97.7% of the words. It recovered 61.1% of the structure. That 36-point gap was the first time I could see the problem instead of just living inside it. The vocabulary transferred because the definitions were written carefully. The edges didn't, because the edges were the part I'd let the extraction handle. And the whole time, querying the graph had felt complete. The structure came back typed, connected, confident-looking — so I stopped looking. I started calling it premature retrieval closure: the retrieval returns something shaped like a whole answer, which is exactly why I didn't notice the parts that were missing. Part 10 of Building at the Edges of LLM Tooling . If you're running a long-term project through an LLM-backed memory system (anything that turns raw sessions into structured, persistent memory), this is about the step where the structure starts lying about how complete it is. Start here . Why It Breaks Every memory system of this kind does the same move. An LLM reads raw interaction (a conversation, a document, a session log) and lifts structured memory out of it: entities, facts, rules, summaries. That structured memory becomes the thing the agent reads later, instead of the raw record. The lift is where fidelity goes. Pulling clean structure out of messy text means making decisions the text didn't make explicit: which entity this pronoun refers to, whether a relationship is real or inferred, what to keep and what to drop. Those decisions can be wrong, and when they are,

Navigating the tech space today often feels like walking a tightrope between two extremes: massive corporate monopolies holding all the keys, and idealistic local projects trying to build everything from scratch. But this doesn't have to be an "Us vs. Corporations" battle. We don’t need to completely eliminate corporate tools; we need to leverage them. The real pragmatic goal is to use localized, decentralized data-driven systems to solve real-world physical problems on the ground, in real time. When people hear the word "decentralized," they often assume it means chaotic fragmentation, isolation, or losing control of data. It doesn't. Decentralization does not mean losing data; it means movement. In fact, the paradox of modern tech is that More Decentralized Data = Centralized Utility. 1. Moving Beyond "App Consumption" to Localized Edge Data For too long, the cultural conversation around tech has been stuck in the clouds. We talk about "the cloud" abstractly, and the average consumer's tech vocabulary is limited to a handful of corporate app names. True tech pragmatism brings data collection back down to earth, turning communities from passive consumers into active, node-operating contributors. Here is what that looks like in practice: Hyper-Local Climate Grids: Instead of teaching students about weather patterns using generic data from an airport weather station 50 miles away, a school can deploy its own low-cost local weather station. Students learn from their immediate microclimate, and that real-time local data is fed back into a wider community grid. Optimized Infrastructure: Instead of spending millions on speculative traffic studies, we can use existing, low-cost edge cameras to count traffic patterns locally. This decentralized edge data tells planners exactly what kind of infrastructure—like traffic lights (or "robots" as we call them here) or bypass lanes—a specific zone actually needs. It is planning based on true utility, not guesswork. The Energy Grid
