A friend of mine plays fretless bass, and we have a long-term goal: record multisamples of their playing and turn it into an original Kontakt instrument. But sampling takes time and preparation. So as a first step, I decided to build a KSP script plugin to control an existing bass instrument — learning the tooling before the real recordings happen.

This is the record of writing that KSP (Kontakt Script Processor) script: implementing portamento, slide-in, and vibrato, and everything that went wrong along the way.

After reading an article about FuruBass-Fretless, I thought: "I could build a Kontakt instrument myself."

Reader, I was not prepared.

KSP (Kontakt Script Processor) is far more opinionated than it looks. Implementing a single portamento effect ate half a day.

My Docusaurus blog runs on GitHub Pages, built by GitHub Actions. The problem: every push turned into a merge nightmare because my local machine and CI were both writing to the same blog/ directory.

Got a Google Search Console notification that the fix for "Alternate page with proper canonical tag" was incomplete. The culprit turned out to be a mismatch between how GitHub Pages handles trailing slashes and the canonical URLs Docusaurus generates.

Microsoft AI Tour for Partners に参加した際に、NVIDIA提供のハンズオンセッション「RAG Pipeline with Nemotron on AKS」を体験した。MicrosoftパートナーとしてAzureとNVIDIA双方の技術スタックが組み合わさるセッションで、実際にコマンドを叩いてシステムを動かせる内容だった。

Azure上でNVIDIAのRAG Blueprintを動かすハンズオンに参加した。Helmコマンドを数回叩くだけでLLM推論・ベクターDB・ドキュメント取り込みパイプラインが一括起動し、PDFに質問できるUIまで立ち上がる体験は、想像以上に示唆が多かった。

手順を追いながら気づいたことを記録しておく。

After reading eda-san's (@eda_sann) article "Turning Book Knowledge into Agent Skills — System Design Principles Edition," I was inspired to build the same thing myself — this time for GitHub Copilot.

While eda-san used Claude Code's Agent Teams, this article takes a different angle:

• Ported to GitHub Copilot (VS Code Agent Mode)
• A close look at the structure and format of a Skill
• A demo of it running in practice

On March 31, 2026, two security incidents hit the npm ecosystem simultaneously.

The first: Anthropic forgot a single line of configuration and accidentally published the entire source code of Claude Code. The second: the npm account for axios — a package downloaded 100 million times a week — was hijacked and used to distribute malware. The two incidents are completely different in nature, but both shook trust in npm as infrastructure.

Following the SEO and performance improvements on the portfolio side (previous article), I turned my attention to the Docusaurus blog on the same day. The starting point was Mobile Performance 94 / Accessibility 94 — not bad, but with room to improve. Running PageSpeed Insights repeatedly kept surfacing new problems. Here's the full record.

A record of going from nearly zero SEO to PageSpeed Insights ALL 100.

Images converted to WebP for 95% reduction, 7.8 MB of fonts removed, JSON-LD/OGP implemented — everything the code could address, all done. Including some surprising traps along the way, like Cloudflare's email obfuscation.

I investigated whether a private MCP server can be registered with Azure Foundry Agent Service. The short answer: not currently. Having understood that constraint, I also laid out the security risks lurking in MCP-based architectures.
