3 月初日の日記を落としてしまいました。 そんな今日は、OR 学会を聴講してきました。 大学を出て以来の学会参加でしたが、やはり楽しいですね。 学生の身分から解放された今になって、ようやく研究というものを客観的に見ることができるようになった気がします。 いや、学生のうちからそれができていたら、どんだけよかったことか・・・。
私が一番好きな本、高田純次の『人生の言い訳』をもう一度読み直そうかな。 どこに置いたっけ、と思ったら机の真横にあったのを見つけました。 これって運命ですかね、違いますね(笑)

Reno 5 A、防水防塵とFeliCaがあってReno Aの正統後継という感じがして気になってる
A1.FlexがSingle 1882.0でM6gがSingle 1649.2らしいからA1.Flexのほうが高い https://blog.luispc.com/entry/2020/05/18/190613

超えた場合のエラーメッセージが

だから4vCPU/24GB x1でもいいし1vCPU/6GB x4でもよさそう
A1.Flexは4vCPU/24GBの枠の範囲内でインスタンスを立てれるっぽくてE2.1.Microみたいな2台制限ではなさそう
