Update on this: There have been allegations that he faked it, and while I normally just trust that folks in this community are doing what they say they're doing because there aren't like any prized for faking shit, the evidence (spectrum analysis of the audio vs his other videos, including fan noise and frame vibrations) suggests it was recorded at 30 fps and speed-doubled. Guess we'll see how this plays out. This does match the cooling performance being roughly double what I thought possible with this equipment.<\/p>","url":"https:\/\/hachyderm.io\/@dalias\/116167476607481666","status_net":{"notice_id":null},"inReplyTo":{"objectType":"note","id":"https:\/\/hachyderm.io\/users\/dalias\/statuses\/116165958370668729","url":"https:\/\/hachyderm.io\/@dalias\/116165958370668729"}},"to":[{"objectType":"http:\/\/activitystrea.ms\/schema\/1.0\/collection","id":"http:\/\/activityschema.org\/collection\/public"}],"status_net":{"conversation":"tag:gnusocial.jp,2026-03-03:objectType=thread:nonce=1199221bb7a3c162","notice_info":{"local_id":"12227354","source":"ActivityPub"}},"published":"2026-03-03T21:57:03+00:00","provider":{"objectType":"service","displayName":"GNU social JP","url":"https:\/\/gnusocial.jp\/"},"verb":"post","url":"https:\/\/hachyderm.io\/@dalias\/116167476607481666"},{"actor":{"id":"https:\/\/hachyderm.io\/users\/dalias","displayName":"Rich Felker","status_net":{"avatarLinks":[{"url":"https:\/\/gnusocial.jp\/avatar\/40873-original-tmp20221202140938.webp","rel":"avatar","type":"image\/webp","width":400,"height":400},{"url":"https:\/\/gnusocial.jp\/avatar\/40873-96-20221207231635.webp","rel":"avatar","type":"image\/webp","width":96,"height":96},{"url":"https:\/\/gnusocial.jp\/avatar\/40873-48-20221207231635.webp","rel":"avatar","type":"image\/webp","width":48,"height":48},{"url":"https:\/\/gnusocial.jp\/avatar\/40873-24-20221207231635.webp","rel":"avatar","type":"image\/webp","width":24,"height":24}],"profile_info":{"local_id":"40873"}},"image":{"url":"https:\/\/gnusocial.jp\/avatar\/40873-96-20221207231635.webp","rel":"avatar","type":"image\/webp","width":96,"height":96},"objectType":"person","summary":"C librarian, purveyor of the language's eldritch horrors.
