A quietly practical sweep today. Hardware on one side — Sharp squeezing more sensors into a two-week smart ring, and a flat NTN antenna that lost nearly half its weight — paired with infrastructure stories like Mazda scrubbing tape archives and dropping capacity cost by a factor of ten. On the software side, Git 2.55 and ParrotOS 7.3 keep tightening the developer loop, while Microsoft Build is pushing security upstream into the tools we already use. The throughline: fewer compromises at the edges, more capacity where it counts.

• シャープが2週間充電不要で100m防水の新型スマートリングを発売 (MONOist 最新記事一覧) (In Japanese Language)
  Sharp is releasing a smart ring that uses four high-precision sensors to measure vital data and other metrics. Worn on the finger, it automatically tracks heart rate and sleep state, syncs with a dedicated app, and runs up to roughly two weeks per charge with 100 m water resistance.

• 平面アンテナを47％軽量化、ドローンや車両などへ搭載可能に (MONOist 最新記事一覧) (In Japanese Language)
  Japan’s National Institute of Information and Communications Technology (NICT) and partners have cut the weight of flat antennas aimed at NTN (non-terrestrial network) use by 47%. The redesign folds in a new heat-dissipation device and has been confirmed operating as a satellite-communications terminal that can be mounted on drones.

• バージョン管理システム「Git 2.55.0」リリース ─ Linuxで組み込みfsmonitorに対応 (thinkit.co.jp) (In Japanese Language)
  Git 2.55.0 was released on June 29, 2026. Highlights include a built-in fsmonitor daemon for Linux, incremental repacking driven directly from multi-pack index (MIDX) files, and parallel execution of compatible hooks defined in the config file. Git remains the de facto standard open-source distributed version control system for source-code management.

• セキュリティに特化したLinuxディストリビューション「ParrotOS 7.3」リリース ─ 最新CPU向けの最適化パッケージを提供 (thinkit.co.jp) (In Japanese Language)
  ParrotOS 7.3 was released on June 29. The Debian-based distribution aimed at white-hat hackers now ships packages optimized for x86-64-v3 and ARMv8.2-A CPUs, adds a redesigned menu system, and offers an official Vagrant box. Alongside the Security Edition, the Home Edition targets everyday and developer use.

• マツダが"脱テープ"で「遅い」の声をなくし、容量単価まで約10分の1に　その方法は？ (＠IT NewsInsight 最新記事一覧) (In Japanese Language)
  Facing an explosion in engineering and design data, Mazda overhauled its storage infrastructure. The new setup removes the need to retire data to tape and cuts cost-per-gigabyte to roughly one-tenth of the prior level. The piece walks through the architecture choices behind the migration.

• 「脆弱なコード、データ漏えい、侵害され得るモデル」　開発者の不安をMicrosoftはどう解消するのか (＠IT NewsInsight 最新記事一覧) (In Japanese Language)
  At Microsoft Build 2026, Microsoft announced new security tools and features that protect code, AI agents, and models across the entire development lifecycle. The strategy pushes security upstream — embedding it directly into the tools developers already use — with the goal of delivering speed and safety together.
