江端さんの技術メモ

木材から円形(円盤)を切り出すことが必要となり、色々試しています。

このような、電動ドライバーに装着できる、木材用の円切りサークルカッターを使っていました。

しかし、これで作業すると、直径20cmの円を切り出すのに、(慣れてきても)10分以上はかかるので、非常に効率が悪く、恐しく疲労します。

そこで、今回、BOSCH(ボッシュ)の電動ノコギリを使って木板を円形に切ることのできる、BOSCHのジグソー円曲平行ガイドを購入しました(別の会社の電動ノコギリの場合、その会社が提供しているものを購入する方が安全です)

先程、自宅に届いたので、さっそく、自分のメモとしてジグソー円曲平行ガイドを、袋から取り出すところから、切り出すまでの全行程を撮影しました。

映像の中では、キレイな円形の切出しに失敗していますが、これは中心線をズラさないようにすれば、必ず成功しますので御安心下さい。

サークルカッターと比較して、もの凄くラクチンに円盤を切り出せました。

スマホから位置情報を取得するところまできたが、https(wss)対応にしないと位置情報が取り出せないようです(かなりしつこく聞いていましたが、すっかり忘れていました)。

で、今のGolangのサーバプログラムをhttps対応にすべく、色々試したのですが、なんかこれで動いているようなので、要点だけ記載します。

Step.1 

まず、

C:\Users\ebata\WssSample\goClient>go run goClient.go conn.go hub.go tls: first record does not look like a TLS handshake がなんともならない件

の、mkcertを使って生成した鍵(“algo.key"と"algo.crt")をディレクトリに放り込む

Step.2

serverXX.goの、サーバ作成部を以下のように変更する

/*
		log.Fatal(http.ListenAndServe(*addr, nil)) // localhost:8080で起動をセット
	*/

	var httpErr error
	if _, err := os.Stat("./algo.crt"); err == nil {
		fmt.Println("file ", "algo.crt found switching to https")
		if httpErr = http.ListenAndServeTLS(*addr, "algo.crt", "algo.key", nil); httpErr != nil {
			log.Fatal("The process exited with https error: ", httpErr.Error())
		}
	} else {
		httpErr = http.ListenAndServe(*addr, nil)
		if httpErr != nil {
			log.Fatal("The process exited with http error: ", httpErr.Error())
		}
	}

Step.3

htmlファイルの、"http://"を、片っ端から"https://"に書き換える。

さくっと動いて気持ち悪いのですけど、まあ動くのであれば、なんでも良いです。

スマホから使えるようにした(今は、ランダムウォークだけ)。

RUN add-apt-repository ppa:bitcoin/bitcoin を ppa:luke-jr/bitcoincore に変更してみたら、Dockerfileが通った

ターミナルを開いて、コンテナに入ります。
docker exec -it bitcoin_1 /bin/bash
 root@bitcoin_1:/# bitcoind -daemon Bitcoin Core starting root@bitcoin_1:/# bitcoin-cli generate 100 error code: -32601 error message: Method not found

あれ？

bitcoin-cli getinfoで確認出来るって書いてたけど、もう無くなったAPIになっちゃてたみたい。

This command doesn't exist anymore since Bitcoin Core 0.19. Use generatetoaddress instead. てなことが記載されている。

ここを読んでみると、

Generate 11 blocks to myaddress
> bitcoin-cli generatetoaddress 11 "myaddress"
If you are running the bitcoin core wallet, you can get a new address to send the newly generated bitcoin to with:
> bitcoin-cli getnewaddress

てな記載がある。

とにかくブロックを作らんことには、金(ビットコイン)が稼げないが、上記の"myaddress"が何ならよう分からん。

ここ の記事にある、bitcoin-cli generatetoaddress 101 `bitcoin-cli getnewaddress`

をやってもいいものなのか？

ちなみに、bitcoin-cli getnewaddress を実行すると、

root@bitcoin_1:/# bitcoin-cli getnewaddress
bcrt1qymag0kvldyw4saejksnssv92ss3awrkp5vz6ef

てな内容が出てくる(アドレス、モロばれだけど、実際の環境では使わないからいいかな)

で、やってみた。

root@bitcoin_1:/# bitcoin-cli generatetoaddress 101 `bitcoin-cli getnewaddress`

うん、なんかブロックできたみたいだ。

うん、できている。では金額を確認してみよう。

おお！ 凄い。今1BTCが120万円くらいだから、6000万円を作ってしまったぞ！ 

では、ここで口座(アカウント)を作ってみよう。

でもって、残高を調べるけど・・・

PruneClusterのマーカを一個づつ消すには、面倒でも以下のようにしなければならない

for (let i = 0; i < markers.length; ++i) {
				if (obj.id == markers[i].hashCode){
					console.log(i)
					console.log(obj.id)										
					console.log("obj.id == markers[i].hashCode")

					//leafletView.RemoveMarkers(markers[obj.id]);  // これでは消えてくれません
					// 1つのマーカーを消すのに、面倒でも以下の2行が必要
					var deleteList = markers.splice(i, 1);					
					leafletView.RemoveMarkers(deleteList);

					// 以下失敗例リスト
					//leafletView.RemoveMarkers(markers[i].hashCode);  //これはダメ
					//leafletView.RemoveMarkers(markers[obj.id],'item');
					//leafletView.ProcessView(); // 試しに入れてみる
					//leafletView.RemoveMarkers(markers[i-1]);
					//leafletView.RemoveMarkers(markers);					
					break;
				}
			}

ちなみに、インターバル関数で、定期的にProcessView()を叩いておかないと更新されないことにも注意のこと。

// 位置情報の更新
    window.setInterval(function () {
        leafletView.ProcessView();  // 変更が行われたときに呼び出されれなければならない (ここでは1000ミリ秒)
	}, 1000);

• 背景
  • 事業部に散々脅かされた
  • 「もし、ハックされたら研開(というか江端一人)で責任取れよ」と念を押された
  • AWSコンソールは、江端のみにログイン権限があるので、ここからいじるのは難しいそう
• 江端予測
  • EC2への直接の攻撃・または侵入
    • 一応SSHアクセスはできる状態
    • SSHによる攻撃はかなり難しいのではないか(秘密鍵がある限り)
  • EBLへの攻撃・または侵入
    • 無闇なアタックはできるだろうが、内部に入ることはできないのでは？
  • 取られる情報
    • 個人情報はないので、個人情報の流出は不可能だが、ユーザ利用情報やら運行情報が取られる可能性もある
• 江端が調べた範囲のこと
  • SQLインジェクション
    • WebからSQLに触れないので意味なし
  • XSS（クロスサイトスクリプティング）
    • Webサイトのリンクは限定的であり、外部から改竄される余地がない
  • バッファオーバーフロー
    • ELBでEC2を保護しているから、サービスは落せない(？)
  • WebDAV
    • 本サービスでは使っていないので関係なし
  • FTPS(FTP over SSL)やSFTP(SSH File Transfer Protocol)等)を採用しているか
    • FTPサーバ上げる予定がないので、自動的にこれを採用することになる
  • メールサーバ
    • メールサーバがない
  • CMS
    • 使用しない
  • 意図しないサーバへのゾーン転送の防止
    • 発生しえない
  • 安全なHTTPS通信
    • TLSを利用したhttps通信を使用
  • 社外公開サーバ セキュリティ対策リスト_20191007.xlsxにて確認済み
• 江端不明点
  • EC2からIAMを書き換えることって可能なのか？

キーワード: 切取り、切り取り、削除、圧縮、キャプチャ、画面、編集、

■VideoSmaller →動画のファイルサイズをオンラインで小さくする

■Avidemux/aviUtl→動画(mp4)のいらん部分を切りすてる

■amuseGraphics → これは使ったことないなぁ

■AG-デスクトップレコーダー → PC画面をキャプチャする(使い倒している)

■RealPlayer →wmvファイルをmp4に変換するのに使っている(ちなみにVLCでは、結構な音ずれが発生する)

goルーチン対応完了。通信情報を全部ルーチンの中に突っ込んで、さらにサーバの方を、リクエストを一回つだけしか受けつけないようにミューテックスでロックしてみた。ただし動作は、まだ不安定。
