Today’s Japanese-language tech headlines cluster around three threads, and I think they’re worth reading together. First, hard infrastructure: GF and Qualinx are showing what EU chip sovereignty actually looks like on a fab flow, while Norway’s Rogfast tunnel is pushing deeper into bedrock than anything built before. Second, resilience under climate stress — Europe’s heat wave is squeezing both AC demand and nuclear output at the same time, and that’s a story worth watching. Third, the quieter side of the ecosystem: a fresh Rakudo release for the Raku community, and a methodology that treats slide decks as code. Engineers are swinging between continents and codebases this morning.

• 半導体主権の「現実解」　GFとQualinxが欧州域内製造フロー実証 (EE Times Japan 最新記事一覧) (In Japanese Language)
  GlobalFoundries (GF) and Qualinx completed a GNSS SoC manufactured entirely within Europe, keeping sensitive design data, masks, and wafers under European control — described as a concrete step toward semiconductor sovereignty. EDA tools and materials remain open challenges.

• 熱放射を自在に操る新たな光デバイス提案、大阪公立大ら (EE Times Japan 最新記事一覧) (In Japanese Language)
  A research group led by Osaka Metropolitan University has theoretically proposed a new optical device that can freely control the direction of thermal radiation. The team plans to fabricate the device and verify its operation going forward.

• 「Rakudo 2026.06」リリース ─ Perl 6として開発が開始された「Raku」の実装 (thinkit.co.jp) (In Japanese Language)
  The Rakudo team released Rakudo 2026.06 on June 27. Rakudo is the implementation of Raku (formerly Perl 6), a dynamic language known for regex, concurrency, grammar definitions, and a strong type system. Highlights include new optimization stages in RakuAST, constant folding for pure infix operators, simplification of constant-condition ternary and short-circuit logic, a new :end named argument on split, a bits method on native int/num, and fixes including a memory leak in datagrams.

• スライドも「コード」として管理する。MarpとCI、AIで実現する、高品質で持続可能な資料作成 (thinkit.co.jp) (In Japanese Language)
  Stella Security CEO Kotake (@tkmru) writes about managing presentation slides as code using Marp, CI, and AI tooling to keep talk materials sustainable and high-quality, drawing on his experience speaking at events like AVTOKYO 2025.

• 需要は増え、供給は細る——熱波が欧州の電力網を圧迫 (MITテクノロジーレビュー) (In Japanese Language)
  The heat wave sweeping Europe is straining the power grid on both sides: air-conditioning loads are surging demand while nuclear plants are squeezed on supply. Changing seasonal patterns driven by climate change are making the demand side harder to match in some regions.

• 世界最長の海底道路トンネル 海面下300mの掘削現場に 本誌記者が潜入 (MITテクノロジーレビュー) (In Japanese Language)
  Under construction in Norway, the Rogfast subsea road tunnel will be the world’s longest and deepest once complete — 26.7 km long, with the deepest section reaching 390 m below sea level. A reporter visits the worksite where crews blast through bedrock, advancing the bore only meters at a time.
