噛み癖を治すために

  • 噛みたいという欲求を解消する必要がある
  • ケージから出して、引っ張り合いをして遊んであげる
    • おもちゃの種類をふやす 10種類くらい用意して飽きさせないように
    • 紐や人形などで引っ張り合いをする
      • 引っ張りで噛む力を発散させる
    • 大きく振り回すと歯を炒めるので、小刻みに引っ張る
    • あそぶときに手をかんだらやめる

Created May 23, 2019
async/awaitとpromise使えばモナド糖衣構文っぽいの書けそうだよねって思って書いてみたけど、async () => {} でwrapしないといけないしまぁそんなにきれいに書けなかったって話。でもこういう邪悪なことやる関数型厨いそうですよね？(オマエだよ)

this.value = value

GoでhttpsをMiTMするProxyの作り方メモ
View mith_proxy_in_go.md

GoでhttpsをMiTMするProxyの作り方

  1. CONNECTメソッドのリクエストから、http.Hijackerを使って生のTCPコネクションを取り出す
  2. クライアントには200 okを返す
  3. 接続先ホストの証明書を、予め用意してあるroot証明書でサインして生成する
  4. 生成した証明書でクライアントとtls接続を確立する (root証明書が登録されていないとブラウザで警告が出る)
  5. goroutine起こして、クライアントとのtls接続からhttp requestを読み込む
  6. 受けたhttp requestをそのまま接続先hostに送信する
  7. 接続先hostからのhttp responseを、クライアントtls接続に書き込む
  8. EOFが来るまで 5-7繰り返し

Sentryをdocker-composeで。
View README.md
  1. docker run --rm sentry config generate-secret-key でSECRET_KEYを生成する
  2. SECRET_KEYを環境変数にいれる export SENTRY_SECRET_KEY="your generated secret key"
  3. docker-compose up -d でサービスあげる。
  4. docker-compose run -rm sentry sentry upgrade で初期設定する
  5. docker-compmse restart で再起動
  6. Go http://localhost:9000 and get sentry!
