[yt-dlp]Investigation for logger output to log file

As Youtube-DL was not extended any more, I turned to yt-dlp also.

But it has an insufficient feature to output debug log to stdout. In my program, I need it to output debug log to log file instead of output to stdout.

After take some time to investigate the source, I found that I need to change one method in below file.

yt-dlp/yt_dlp/utils/_utils.py
Method: write_string

Its source below:

def write_string(s, out=None, encoding=None):
    assert isinstance(s, str)
    out = out or sys.stderr
    if not out:
        return

    if compat_os_name == 'nt' and supports_terminal_sequences(out):
        s = re.sub(r'([\r\n]+)', r' \1', s)

    enc, buffer = None, out
    if 'b' in (getattr(out, 'mode', None) or ''):
        enc = encoding or preferredencoding()
    elif hasattr(out, 'buffer'):
        buffer = out.buffer
        enc = encoding or getattr(out, 'encoding', None) or preferredencoding()

    buffer.write(s.encode(enc, 'ignore') if enc else s)
    out.flush()

As per the source, we can add out put log file parameter to it.

[AWS EC2]Docker install

AWS EC2にDockerを利用して、Wordpressを使い始めたいと思いますので、AWS EC2にDockerインストールをメモしておきます。

1. EC2インスタンスにログインして、最新のyumリストを取得します。

$ sudo yum update -y

2. Docker packageインストールします。

$ sudo yum install -y docker

3. Dockerサービスを起動します。

$ sudo service docker start
Redirecting to /bin/systemctl start docker.service

4. Dockerグループにec2-userを追加します。

$ sudo usermod -a -G docker ec2-user

5. 一旦ログアウトして、再度ログインすることで、設定を有効化します。docker infoでdockerの起動を確認します。

exit

$ docker info
Client:
 Version:    25.0.3
 Context:    default
 Debug Mode: false
 Plugins:
  buildx: Docker Buildx (Docker Inc.)
    Version:  v0.0.0+unknown
    Path:     /usr/libexec/docker/cli-plugins/docker-buildx

Server:
...

Although we did not face below issue, if you have the problem, please follow AWS guidance to restart the instance.

Cannot connect to the Docker daemon. Is the docker daemon running on this host?

[VS CODE]HTMLをリアルタイムでプレビューする方法

Web制作の過程でリアルタイムプレビューを使いたい場合、Visual Studio Code（VS Code）の利用をおすすめです。

Visual Studio Code（VS Code）はマイクロソフトが提供している無料のコードエディタです。昔はAdobeのDreamWeaverを利用し、非常に高機能で使いやすかったが、MACのOSアップデートで、一括支払いバージョンからSaaSになって、高額で諦めました。

「コードエディタを使ってリアルタイムプレビューの環境を作る」と聞くと難しそうな印象を受けるかもしれませんが、実際は非常に簡単で3分ほどで完了します。

「VS CodeのUI上でプレビューする方法」があります。まずはVS Codeが必要なので、下記のページからダウンロードしてPCにインストールしましょう。

https://code.visualstudio.com/download

VS CodeのUI上でプレビューできる拡張機能もあります。ExtensionsからHTML Previewと検索し、下記が表示されたらインストールしてください。

ファイルに戻り、command + Shift + P（Windows：Ctrl + Shift + P）を押すと上に表示される検索窓から、HTML: Open Preview the the Sideを選択します。そうすると、右にプレビュー画面が出てきて、所見既所得....

DreamWeaverのような高機能ではありませんが、基本的なHTML、CSS、Javascriptについて、問題がありません。ただし、Pluginの開発は2018からすでに停滞しているので、いつかに使えなくなるのが心配です。

まだ、問題となりのがリンクです。プレビュー画面からリンクを経由でNext Pageの確認が不可です。全てAzureに誘導され、Azureの共有リンクから探しているようです。設定不備かエンジンのバグだと思います。

[youtube-dl]Blocked?

 Just want to confirm if there is any newer version for YouTube-dl, unfortunately, it was blocked by de court...

It was shown that [Access denied] to yt-dl.org due to a ruling of the Hamburg Regional Court.

Access to this website is blocked.

So, we still have another way.

https://github.com/ytdl-org/youtube-dl

But it seems that it stopped development since 2021.

ーーーーーーーーーーーーーーーSuper beautiful seperate lineーーーーーーーーーーーー

After asked Google, I found the below repository.

yt_dlp

We can make some change on script to work on yt_dlp rather than Youtube_DL.

[Panasonic]CF-SZ6 Fixed a SZ6 LCD Screen

Fixed a Panasonic CF-SZ6 LCD Screen, but found that although it passed the selftest, but failed on startup beep.

Why?

Changed the module board, but it can not work fine yet.

Maybe motherboard connecter broken.
