Morning, scouts. The big story out of Japan right now is football — Japan’s national team just put on a statement performance against Tunisia, with Ueda bagging a brace on the biggest stage after a tough last cycle. Off the pitch, the developer feeds are humming too: a major mail server gets a C++ rewrite, a Debian-Testing-based distro refreshes its semi-rolling ISO, and a couple of Zenn articles are wrestling with how to keep observability alive as DNS and SNI increasingly hide inside encrypted tunnels. Sports dominance, infrastructure maintenance, and "how do you even see this anymore" debugging — pretty classic Sunday.

• Ace Ueda Kise scores twice, delivers on the big stage【Analysis】 (NHKニュース) (In Japanese Language)
  NHK explains how striker Ueda Kise — the first Japanese national team player to score twice in a single World Cup match — turned his bitter experience from the last tournament into a starring role in Japan’s rout of Tunisia.
• Japan beats Tunisia 4-0 in World Cup — Kamada, Ueda, Ito on the scoresheet【Details】 (NHKニュース) (In Japanese Language)
  Japan’s 4-0 win over Tunisia on June 20 (JST June 21) is the first time Japan has scored four goals in a single World Cup match; the result pushes them to four points (one win, one draw) in group play, with manager Moriyasu and post-match player comments plus new records covered later in the piece.
• "Courier Mail Server 2.0.0" released — major update (thinkit.co.jp) (In Japanese Language)
  The legacy mail server project ships a major version bump, with IMAP and MIME code migrated to C++, SqWebMail improvements, and stronger compliance with RFC 6533 (internationalized email).
• "SparkyLinux 2026.03" released — semi-rolling ISO refreshed, ships Linux 6.19 (thinkit.co.jp) (In Japanese Language)
  The lightweight Debian Testing-based distribution publishes a new semi-rolling ISO built on the "Forky" branch with packages as of June 17; existing users can upgrade through normal system updates rather than reinstalling.
• What does a memory dump actually look like? (hands-on edition) (Zennのトレンド) (In Japanese Language)
  A practical follow-up to a 2019 Kame note about how memory dumps actually look under the hood; the author uses the older piece as a jumping-off point and notes up front that they hover around the entryway rather than going deeper.
• Observing outbound traffic in an era where DNS and SNI are harder to see (Zennのトレンド) (In Japanese Language)
  A standalone companion to two earlier posts on tracking outbound traffic in dev/CI environments, arguing that with encrypted DNS and encrypted SNI you increasingly need to correlate which process, which file, and which destination fired — especially during package installs or after touching credentials.
