SvelteKit 2: Code-based router instead of file-based router now is just a Gist!

The idea is simple — just create universal [...path] folder and proxy everything through it specifying patterns in some urls.ts. So, we have to create minimal and universal +page.js and +page.server.js with load functions, find there 'pattern' in urls.ts by url.pathname we know in load, set some routeStore, containing desired page, and get it in +page.svelte. It's kinda tricky, so we also need c...

Governance metadata in A2A Agent Cards, shipping the superset

A2A Agent Cards describe what an agent can do, where it lives, and how to talk to it. What they do not describe is governance posture. Two agents can hold identical cards and behave nothing alike in production. We shipped a reference implementation under extensions.asqav.governance inside the standard AgentCard envelope. Three fields carry the posture: trust_score, retention_ttl_seconds, and deri...

DocuSign Alternatives in 2026: What to Look for in an E-Signature Platform

DocuSign pioneered the e-signature category, but in 2026 the landscape looks very different. Teams evaluating e-signature tools have dozens of options, each optimized for different use cases — embedded signing for SaaS apps, AI-powered form generation, industry-specific waivers, or pure API-first workflows. This guide breaks down what actually matters when choosing an e-signature platform, the t...

How I Passed the GH-200 Exam Without Increasing My Study Hours

I work in an Azure-focused systems and cloud administration role, so GitHub Actions was already part of my day-to-day life before I decided to take GH-200. I was not walking in as a beginner. I had already written workflow files, handled secrets, fixed broken jobs, and connected GitHub automation to real delivery work. That experience helped, but it also gave me the wrong kind of confidence. I tho...

Beyond Page Speed: Why Every Developer Needs a Warmup Cache Request Strategy

Every website owner has faced this "invisible" performance killer: You push a fresh update, clear your server cache, and suddenly your site feels sluggish. For that first visitor, the experience is frustratingly slow. The culprit isn't your hosting—it's a Cold Cache. This is where mastering the Warmup Cache Request becomes a critical skill for modern web performance. The Problem: The "First Load...

Multi-Agenten-Systeme: Wenn KIs miteinander arbeiten

Stell dir vor, du willst einen langen Bericht über den deutschen Wohnungsmarkt erstellen. Du bittest eine KI darum. Sie recherchiert, schreibt, zitiert und liefert dir nach fünf Minuten einen Text, der gut klingt, aber bei näherer Betrachtung Zahlen aus 2023 enthält, eine Quelle falsch zitiert und einen zentralen Trend komplett ignoriert. Was wäre, wenn stattdessen drei spezialisierte KIs zusamme...

Introduction to Machine Learning

What is Machine Learning? One of the many subsets of AI that focus on learning patterns from datasets to make predictions or decisions without explicit programming. By training algorithms on large datasets, these models generalize to new data, powering applications like image recognition, recommendation engines, and language models. Types of Machine Learning. 1.sup...

# Building Solana data flows: Using n8n to automate block height extraction through GetBlock’s RPC infrastructure

The Solana ecosystem moves incredibly fast. With block times sitting around 400 milliseconds, anyone building automated workflows, indexing tools, or real-time analytics dashboards runs into one major challenge: RPC reliability and latency. If you depend on overloaded public endpoints, your automation is always one delay away from breaking. When a pipeline starts lagging or drops requests, the wh...

Reasoning Models sind kein Upgrade, sie sind ein anderes Werkzeug

Stell dir vor, du bezahlst für ein Modell das viermal so oft falsch liegt und vierzehn mal so viel kostet wie das Standardmodell. Das klingt absurd. Und es ist passiert: In einer Evaluation von splx.ai aus 2025, die o3-pro gegen GPT-4o in einem Versicherungs-Use-Case getestet hat, verlor das "bessere" Modell auf ganzer Linie. Das ist nicht das Versprechen, das OpenAI macht, wenn es Reasoning Mode...

corpus: self-hosted listenbrainz and last.fm frontend

Works as a self-hosted proxy that fetches listening history from either Last.fm or MusicBrainz, adds metadata from MusicBrainz (falling back to Last.fm and Discogs) and caches cover images to an S3 bucket. Everything is stored in DuckDB (each user has their own database) and it's been humming along quite well even for larger profiles (200k scrobbles). I always worry that these services can disappe...

Your AI Security Problem Starts Before the Prompt

Most enterprise AI security conversations start in the wrong place. They start with the model. The prompt. The guardrails. The provider's SOC 2 report. As if risk begins the moment a token hits an LLM endpoint. It doesn't. The decisive security event happens earlier — when your system decides what the data is. If that decision is wrong, every downstream control is working from a compromised prem...

An AI Benchmark That Tests Real Coding Workflows

Developers face a real choice: pick a coding model or agent based on synthetic benchmarks that look great but do not predict actual project work. The problem is no longer whether models can score well on those benchmarks; it's whether those scores still mean anything. Today's benchmarks test narrow skills well, but they rarely capture the full workflow of professional development. I wanted somet...
