研究室のウェブサーバにhttpsで接続できずに焦る。
curlで見てみる。

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
証明書がwww.calc.appi.keio.ac.jpになってる。これで接続すれば良いのか。Chromeがwww.を表示しないので、calc.appi.keio.ac.jpだと思ってたわ。
っていうか、サーバが古いのでなんとかしなければならない。卒論・修論シーズンが終わったらやる。でもその後春の学校が・・・
体調がいまいち。
懸念事項だったガレージの掃除をした。
雪が降った。
修論2編チェックした。
