keras で作った LSTM autoencoder で ELF のノイズ(blue)を学習したもの(red)
学習は jetson nano orin に比べて 7-8倍速そう

Forty-five years ago, #Voyager 1 flew past Saturn and our PWS instrument recorded these #SpaceAudio signals.

Je viens de vibecoder un outil en C pour suivre toutes les connexions séries en provenance de convertisseurs USB/Serie correspondants à une regle udev custom.
Le MESH va être vachement plus facile à explorer.

新しい PC の Windows update 25H2 ではまってしまいました

プリインストールされてた某アプリが試用期限切れ後もファイアウォールとして動いていたのが原因だった模様😑

I was working with these data recently, and realized I've never done a #SpaceAudio release. Here is all of the #Voyager 1 PWS waveform data collected on March 6, 1979, as the spacecraft was leaving Jupiter. (Over 6 hours 43 minutes!)
