Hey all, I made this. The archive started with my 2015 BA thesis on Amiga ASCII art when I was curious about the history of ASCII art but found very little on text art that came before it. The historical precursors are often attributed to typewriter art and shaped/visual poetry, but I think letterpress is overlooked. So, I got slightly obsessed and started a personal database of pictures built entirely from metal type, ornaments, and rule, some going back to the 1600s. After eight years, I've ma

Automating workflows has always been a priority for me, especially for repetitive and error-prone manual processes. Recently, integrating AI capabilities into these automations offers a great opportunity for those, like me, who seek practical solutions. However, this integration often requires coding or complex API integrations. This is where "low-code/no-code" tools like n8n come into play. I used n8n to set up AI-powered agent flows on my own servers, without compromising data privacy and control. In this post, I will share my experience and explain how to do it step-by-step. Why n8n and Self-Hosted AI Automation? A few years ago, I experimented with different automation tools, especially for simple data transfers and notification flows. But when AI capabilities became involved, I either found them too expensive or avoided cloud-based solutions due to data security concerns. Especially in a client project where we needed to set up an automation handling sensitive financial data, a self-hosted solution became inevitable. n8n offers a wide range of integrations and, thanks to Docker support, I can easily host it on my own server. For me, self-hosting is not just about cost advantage; it also means having complete control over my data. Especially when using AI agents, the question of how much of the data you send to LLMs is logged or used for training is always a concern. With an n8n setup under my control, I minimized these worries. Moreover, n8n's flexible structure gives me the freedom to add as many custom integrations or LLM providers as I want. This is a significant advantage for someone like me who enjoys testing different LLMs. ℹ️ Data Privacy Priority Especially when working with sensitive data, it's crucial to carefully review the data usage policies of cloud-based AI services. Self-hosted n8n offers more control in this regard, making it my preferred choice for critical workflows. Setup Steps: Quick Start with Docker Compose The easiest way to run n8n on y

Swift Testing shipped with Xcode 16 back in 2024. Swift Testing was built from the ground up for Swift. That means Swift concurrency is a first-class citizen, test cases run in parallel by default, and the API surface is dramatically smaller than XCTest's forty-plus assertion functions. One macro, #expect , replaces most of them. If you are still on XCTest, you have probably felt the friction: class inheritance for every test suite, function names that must start with test , assertion messages that tell you what the values were but not where the expression came from. Swift Testing fixes all of this. That said, you do not need to migrate everything at once, and WWDC 2026 is emphatic about this. The Migration Strategy: Small Chunks, No Big Bang The session opens with something refreshing: permission to be slow about this. The recommended approach is to leave your existing XCTests where they are and start using Swift Testing only for new tests. Both frameworks can coexist in the same target and even the same file. You do not need a separate test target, and you do not need a migration sprint. The one rule: Swift Testing tests cannot live inside XCTestCase subclasses. Everything else is fair game. Raw Identifiers for Readable Test Names One small quality-of-life improvement worth knowing about from the start: Swift supports raw identifiers using backticks, and Swift Testing takes full advantage of this. import Testing @testable import DemoApp @Test func ` Default climate : tropical ` () async throws { let fruit = Fruit ( name : "Coconut" ) #expect(fruit.climate == .tropical) } No more testDefaultClimateTropical or dealing with camelCase names in test output. The test name is the test name. Interoperability: The Key to Reusing Your Helper Code This is the main new story in WWDC 2026 and the feature that makes incremental migration actually work. The problem: you have test helper functions that wrap XCTFail . You want to call them from new Swift Testing tests. Previously,

Ihre OpenAPI-Datei ist die Quelle der Wahrheit für Ihre API: Pfade, Parameter, Request-Bodies, Responses und Schemas. Für Entwickler im Alltag ist rohes YAML oder JSON aber selten das beste Lesematerial. Backend-Teams brauchen eine schnelle Endpunkt-Referenz im Repository, Frontend-Teams wollen Request- und Response-Felder im Pull Request prüfen, und technische Redakteure möchten Inhalte in Wiki- oder Docs-Systeme übernehmen, ohne Schemas abzutippen. Testen Sie Apidog noch heute Markdown ist dafür das praktischste Zielformat. Es funktioniert in GitHub, Confluence, Notion, Docusaurus, MkDocs, Hugo und jedem Texteditor. Die Aufgabe lautet also: Aus einer vorhandenen openapi.yaml automatisch sauberes Markdown erzeugen. Manuell ist das zu langsam und driftet beim nächsten API-Change auseinander. Automatisch generiertes Markdown bleibt dagegen Teil Ihres Release-Prozesses. Warum Markdown aus OpenAPI generieren? Ein OpenAPI-Dokument ist primär für Maschinen gedacht. Tools parsen es, um Clients zu generieren, Contract-Tests auszuführen, Requests zu validieren oder interaktive Dokumentation zu rendern. Diese Maschinenlesbarkeit sollten Sie beibehalten. Wenn Sie zuerst die Qualität Ihrer Spezifikation prüfen möchten, hilft der Leitfaden zu OpenAPI-Validierungstools . Markdown löst ein anderes Problem: Es macht die API dort lesbar, wo kein OpenAPI-Renderer läuft. Typische Einsatzfälle: README.md oder /docs im Repository Pull-Request-Beschreibungen für neue oder geänderte Endpunkte Confluence- oder Notion-Seiten für Team-Reviews Statische Dokumentationsseiten mit Docusaurus, MkDocs oder Hugo Offline- oder interne Referenzdateien für Support und QA Wichtig ist: Markdown sollte ein abgeleitetes Artefakt sein. Die OpenAPI-Spezifikation bleibt kanonisch, Markdown wird bei Änderungen neu erzeugt. Methoden im Überblick Es gibt keinen offiziellen OpenAPI-Befehl für Markdown-Export. In der Praxis nutzen Teams entweder Konverter, ein eigenes Skript oder eine API-Plattform. Methode Am b

Forget neural networks for a second. The real idea inside this repo is a blueprint for letting AI agents run unattended overnight — and it maps onto problems you already have on your team. If you've been anywhere near tech Twitter or LinkedIn this week, you've probably seen people losing their minds over a small GitHub repo called autoresearch , published by Andrej Karpathy — former Tesla AI director and OpenAI founding member. The framing is dramatic: an AI agent that runs machine learning experiments on its own, overnight, while you sleep. Tweak the code, train for five minutes, check if it got better, keep it or throw it away, repeat. Wake up to a log of a hundred experiments and a model that's quietly improved itself. If you're not an ML researcher, your instinct might be to scroll past. "Cool, but I don't train neural networks. How does this apply to me?" Here's the thing — the neural network part is almost incidental. What Karpathy actually open-sourced is a pattern for structuring AI-agent work: a specific way of dividing responsibility between human and AI that happens to generalize to a huge range of engineering problems. Once you see the pattern, you start noticing places in your own job where it fits. What's Actually in This Repo The repo itself is intentionally tiny — and that's the point. There are really only three files that matter: The evaluator (untouchable). A file containing the fixed constants, data preparation, and the scoring logic. The agent is never allowed to modify this. It's the ruler everything else gets measured against. The implementation (the agent's playground). A single file containing the actual model, training loop, and hyperparameters. This is the only file the agent is allowed to change. Architecture, batch size, optimizer — all fair game. The instructions (the human's only job). A plain Markdown file describing what the agent should try, what the constraints are, how to interpret results, and what to do when something breaks. Ka

Running 23 European e-commerce shops on Payload CMS v3 taught me that some things simply don't exist yet. So I built them. Background I maintain a multi-clone e-commerce infrastructure — 23 Next.js + Payload CMS v3 shops deployed across Europe, each on its own subdomain and language. Think fr.myshop.com , de.myshop.com , sk.myshop.com ... all running on the same codebase with country-specific patches. While building this, I kept running into two missing pieces that no one had published for Payload v3: A customer reviews system with admin moderation and Google star ratings Complete Schema.org JSON-LD for Google rich snippets (Product, BreadcrumbList, ItemList, AggregateRating) Both are now published on npm. Here's what I built, the bugs I hit, and how I solved them. Part 1 — The Reviews Plugin What didn't exist Search npm for payload reviews or payload ratings — you'll find nothing for v3. The official plugin ecosystem covers SEO, forms, redirects, Stripe... but not customer reviews. Building the collection The reviews collection itself is straightforward — relationship to products , rating (1-5), status select (pending/approved/rejected), author fields. The tricky parts came later. Access control gotcha: Payload v3 uses a roles array, not a role string. This breaks if you copy v2 patterns: // ❌ Wrong — always returns false update : ({ req }) => req . user ?. role === ' admin ' , // ✅ Correct for v3 update : ({ req }) => req . user ?. roles ?. includes ( ' admin ' ), Prevent self-verification: Users can POST any field on create: () => true collections. Lock verified in a beforeChange hook: hooks : { beforeChange : [ ({ data }) => { if ( ! data . status ) data . status = ' pending ' data . verified = false // admin-only, always reset on create return data }, ], }, Email protection: read: () => true on the collection exposes authorEmail in the public API. Add field-level access: { name : ' authorEmail ' , type : ' email ' , access : { read : ({ req }) => req . user ?.
