SAP announced the ABAP MCP Server at Sapphire 2026 — the technical foundation for plugging external AI agents like GitHub Copilot, Amazon Q, or Claude Code directly into ABAP development. A look at what the announcements mean technically, what they will cost, and where the gaps remain.

Article 4 of the series — three slash commands make the parser repeatable: /parse-epl for any Einzelplan, /check-totals with built-in pytest, /diff-vs-gesamt for comparison against the full budget. Plus: what xfail reveals about parser gaps.

Article 3 of the series — the first parser code for byhaushalt takes shape via TDD: a custom skill with trigger description, uv setup, six tests before implementation, and how the sum consistency test catches hallucinations in PDF parsing.

Article 2 of the series — before byhaushalt sees its first parser code, Claude Code maps the PDF structure of the Bavarian budget plans. Plan Mode, Explore subagent, and Architecture Decision Records as tools for exploring before implementing.

Article 1 of the series — we install Claude Code, set up the byhaushalt repo, write the first memory file, and pin down what the agent has to follow in every session. Plus: permissions, source data, the first day.

Prologue · Series: Agentic Coding with Claude Code. Anyone reading tech newsletters, conference keynotes, and tool landing pages this year runs into two terms sold with identical promises: Vibe Coding and Agentic Coding. The future of programming, they say.

A new LLM out of Miami promises 12 million tokens of context, linear scaling and a 52× speedup over FlashAttention. We take a close look at what's technically behind it — and where reasonable skepticism kicks in.

Eight articles of theory, one bonus chapter of practice. We combine all the code fragments from the LLM series into a working mini language model, train it on TinyShakespeare, and tack on a tiny SFT step. With a wink to Star Trek TNG.

How a base model that completes text becomes a helpful assistant. Supervised Fine-Tuning, RLHF, DPO, and Constitutional AI — the last piece of the LLM pipeline, with the candid question of what alignment actually solves.

Claude Desktop registers a Native Messaging bridge in seven browser directories without asking — even in browsers that aren't installed. What it means technically, why it violates the ePrivacy Directive, and why Anthropic of all companies is squandering trust here.

Position, depth, stability — what gets added on top of attention to make a complete transformer. Positional encodings, feed-forward layers, residual connections, layer normalization, the entire block in Python, and the leap to GPT, BERT, Llama, and Claude.

Microsoft's 'Windows K2' initiative is meant to save Windows 11 — but doesn't address the root problem. Why Apple is the most plausible answer, and why Linux deserves an app-store approach that doesn't depend on the distribution underneath.

A step-by-step migration strategy away from GitHub, with a focus on CI pipelines. Concrete workflow translation, self-hosted runner setup, why OSS and proprietary builds must not share runners, and a checklist you can tick off.

Tagesschau is shutting down its Apple Messages for Business channel and pointing recipients exclusively to a WhatsApp channel. A license-fee-funded broadcaster is migrating from a privacy-friendlier messenger channel to a markedly more problematic one — and ignoring platform-neutral alternatives along the way.

How the bottleneck of RNNs was replaced by a mechanism that links every token to every other. Query, Key, Value, Multi-Head, and the paper that flipped the NLP world, explained with library metaphors and just enough math for the curious.

A commentary on the Signal phishing affair, the reflex response from a Bundestag Vice President — and the very loud silence of the Digital Minister.

Which code hosting platforms operate without default-on data processing? Comparison table, platform profiles from Codeberg through Gogs and Launchpad to AWS CodeCommit, plus a concrete TDM opt-out implementation.

Since April 24, 2026, GitHub uses Copilot data from Free, Pro and Pro+ accounts for AI training by default. What's behind the change and why it exposes the platform's two-class model.

Why language needs memory, and how the first language models learned that context. Recurrent networks, LSTMs, and the long-sentence problem, explained without a formula storm.

An independent look at GPT-5.5, released April 23, 2026. What the numbers really say, where Claude Opus 4.7 still leads, and why the pricing trajectory should worry developers.

Windows has become a design flaw. Copilot, Recall, TPM sniffing, plus a cloud strategy that costs productivity instead of delivering it. Macs are the rational choice in business. The software argument no longer holds in 2026.

How neural networks learn from errors. Loss, gradients, chain rule, gradient descent — backpropagation implemented by hand on a 2-layer MLP that learns XOR and token prediction.

What happens between embedding and logit. Neurons, layers, forward pass, and activation functions — fully implemented in numpy, no framework magic.

How language models encode meaning in numbers. Embedding tables, cosine similarity, vector arithmetic, and why King minus Man plus Woman equals Queen.

What happens between input and output? Tokens, probability distributions, and sampling strategies — explained step by step, with real code.

Anthropic releases Claude Opus 4.7 with significantly better coding performance, 3.75 megapixel vision, and a new xhigh effort level. An assessment of the benchmarks and the Mythos hint on the side.

The coalition cuts the fuel tax and calls it relief. Nothing changes at the pump — except the profit margins of oil corporations.

An open-source tool that outclasses commercial AI memory solutions — using a 2,500-year-old method, running locally, free, and open source.

Anthropic's Claude Mythos broke out of a sandbox and found thousands of zero-days. An assessment between real risk, methodological gaps, and strategic narrative control.

Why local language models are becoming a real alternative in 2026 — MLX, Unified Memory, and a stack that works without the cloud.

An Obsidian plugin for bidirectional synchronization with BookStack — built with Claude Code as a structured development partner.

Horizontal grids with sections, collapsible lists, star rating with mask, and tap feedback without Button.

The default ColorPicker is a tiny circle. With blur, scaleEffect, and opacity 0.014, you can turn it into a fully customizable button.

Reusable modifiers as View extensions. One design change, one place in code.

The inline Picker swallows its label. A Menu wrapper fixes the problem. Plus: a generic Enum Picker for less boilerplate.
