OpenDedupは結構頑張ってる?


NetBackupのハードウェア互換性ガイドを見ていたら「Datish Systems (OpenDedup)」を発見。

2013年に記事を書いた(Opendedupという重複排除機能搭載のLinux/Windows向けファイルシステム)けど、いまはどうなってるんだろ?と確認してみた

Detish Systems」は、OpenDedup」を開発してる主体の会社である模様。

ただ、どういう会社なのか詳細がよく分からない・・・
なにせAboutを開くと「This is an example of a WordPress page, you could edit this to put information about yourself or your site so readers know where you are coming from. You can create as many pages like this one or sub-pages as you like and manage all of your content inside of WordPress.」とWordpressの初期設定っぽいのが出てくるし・・・

OpenDedup側で調べていく
githubのhttps://github.com/opendedup/sdfsでソースは公開中。

NetBackup Ready」とのことで、OpenDedupのストレージをNetBackupのバックアップ保存先にでき、なおかつ、NetBackupのOSTデバイスとして高速にバックアップ可能な仕組みが用意されているとのこと。

実際のデータ保存先はAmazon S3やAzureなどのクラウドストレージ。

OpenDedupがセットアップ済みの「OpenDedup Virtual NAS Appliance」を使うと、ファイルサーバだけでなく、レプリケーションまで対応出来る模様。

で・・・そこらを含めて、Free。

この会社、どこでカネとるんだろ?
サポートでとるのかと思えば、特に記載はないし・・・謎です

Allwinner H2+搭載のOrange Pi Zeroが来た!


Allwinner H2+搭載のOrange Pi Zeroが、2016/11/02の発注からわずか8日で到着。

zero-4

箱はOrange Pi One/Lite共通箱を流用している模様(・・・とはいっても、うちでOrange Pi Oneを買った時はこの箱じゃなかったんですけどね)

早速開梱!
zero-1

まぁ、いつもの梱包物、といった感じです。
zero-3

改めて見てみると・・・ヒートシンク、どうつけよう?と悩みます。
もうちょっとつけやすいレイアウト考えてくれないかなぁ・・・

そして、「H2+」というチップ上のロゴ。
Allwinner H2とH2+にどのような違いがあるのか・・・これは非常に謎なところです。

で・・・Orange Pi Zeroはシリアルコンソールのみなのですが・・・うっかりしてUSBシリアルを用意するのを忘れていました。
とりあえず、microSDにOSを書き込んで起動テストしてみるか・・・と思ったら、うっかり間違えてAndroidイメージをダウンロードしていました。

Orange Pi Zero用のLinux系イメージを公式からダウンロードしようかと思ったのですが、どれも遅いBaiduのリンクのみ。
Google Driveのアイコンはあってもリンクは無いのです。
Debian ServerについてはGoogle Driveでリンクが設定されているものの飛ぶ先はOrange Pi 2/Orange Pi mini 2向けのイメージという始末。
Baiduからダウンロードをしてみているものの、残り3時間~7時間を行ったり来たりという非常に速度が安定しない感じです。

armbianのOrange Pi Zero向けページに、「check daily beta / preview images」というリンクがあり、そこから開発中のOrange Pi Zero向けイメージがダウンロードして起動試験

2016/11/14追記:正式版がリリースされました。 「Jessie server(Debian)」もしくは「Xenial server(Ubuntu)」をダウンロードします。

なお、rootパスワードは「Getting Started」にあるよう1234です。

正常にOSが書き込まれており、起動が開始したのであれば下記の赤枠部分にあるLEDの上側が緑に点灯します。
状況によっては緑点滅だったり、下側の赤LEDも点滅したりします
zero-6

緑LEDも赤LEDも付かず、RJ45コネクタのLEDのみがついているようであれば、microSDからOSが読み込めていません。

DHCPサーバで該当する時間にIPが払い出されているものを確認して、TeraTermからsshログインを実行
zero-5

正常にログイン完了です。

有線LANは特に問題無し

2016/11/14追記
無線LANも正式版では普通に対応しました。
後述の無線LANのfirmwareを置く作業とかが不要になりました。

無線LANは初物のAllwinner XR819を使っています。
cnx-softwareに記事が出ています
Allwinner H2 Linux & Android SDK, and Allwinner XR819 WiFi Driver Released

XR819のドライバである「xradio_wlan」が読み込めない。
理由は /system/etc/firmware/ ディレクトリにfriwmareファイルが無いから、というのだけど、どこから入手するのか書かれていない・・・
H2-V1.2.tar.gz の中から持ってこい、ってことなんだろうか?

とりあえず無線LANについては放置です。

2016/11/11追記

やはりH2-V1.2.tar.gzの中にfirmwareファイルがあった。

./android/hardware/broadcom/wlan/bcmdhd/firmware/xr819/boot_xr819.bin
./android/hardware/broadcom/wlan/bcmdhd/firmware/xr819/fw_xr819.bin

./lichee/buildroot/target/dragonboard/src/testcases/wifitester/xr819/sdd_xr819.bin

どちらも同じなようなので好きな方のファイルをOrange Pi Zero上の「/system/etc/firmware」ディレクトリにコピーすればokでした。

Orange Pi PCなどAllwinner H3向けのOpenELECについて(2016/11/08版)


Linuxをメディアプレイヤーとして使う方法として、「OpenELEC」というメディアプレイヤーに特化したディストリビューションがあります。
(2016年に分裂騒動があり「LibreELEC」が派生しています)

これをOrange Pi PCなどのAllwinner H3向けに移植したものについて、去年「Orange Pi PCをメディアプレイヤー(OpenELEC)にする」にて紹介しました。

公式スレッド「Openelec Build for OPI PC and 2 now with HW decoding
各機種用イメージ配布場所「Latest prebuilt images
初心者向けQ&A「[FAQ] Openelec OPi for beginners

あれから約1年。
久しぶりに使ってみました。
今回はOrange Pi Oneで実験です。

・初回起動は時間がかかる
 ロゴ画面がずっと変わらず表示されるが、正常動作中です。
 とりあえず5分待ちましょう

・ヒートシンクは必須。ファン付けるの推奨
 フォーラムに「heatsink strongly recomended」と書かれていますが
 ヒートシンクを付けていてもめちゃくちゃ発熱しています。
 ちゃんと冷やさないと熱で死にそうです。

・起動直後の設定は英語表示
 日本語表示にするためには「Linux(ラズパイ/OrangePiなど)のKodiで日本語を表示させる方法」で設定すること

・起動直後の設定だとHDMI経由で音が鳴らない
 初期設定では、音声出力がアナログオーディオとなっているためHDMI接続していても音声が出てこない。
 Kodiの「設定」-「システム」-「オーディオハードウェア」にて
 「オーディオ出力デバイス」を「HDMI」に変更することで、HDMI経由で音声出力される。

・動画再生の一部が変?
 DVDサイズの動画を出力したところ、本来の画質から落ちた状態のものを引き延ばした感じで表示される
 設定変更箇所があるのか分からなかった。

・HDMI経由のリモコン操作が怪しい
 2016/08/16以降のバージョンからHDMI CEC対応になっているのだが動きが怪しい
 今回、試した際は、初回ブートし、途中までは動いていたものの、突如動作しなくなり
 それ以後は電源入れ直しても動いていない状態となりました。
 自動アップデート関連でなにかあったのだろうか?
 FAQにも書いてありますが、動く環境と動かない環境があるようで、作者の方ではお手上げなようです。

 なお、HDMIのリモコンが動かない場合は、マウスで操作するしかありません。
 もしくは、赤外線リモコンを登録して使う、という方法もあります。

TimVideos.us開発のHDMI入力をパソコンに入れるオープンソースハードウェアHDMI2USB


Allwinner H3関連の開発者のgithubを見ていたら、HDMI2USBというプロダクトを発見。

Timvideos.us」という生放送用設備のプロジェクトとして、「ビデオカメラのHDMI出力をパソコン入れるためのハードウェアHDMI2USB」と「複数あるカメラを切り替えて放送に流すためのソフトウェアgst-switch」というものだった。

timvideossetup

で・・・HDMI2USBは結構多機能で、概略としては下記のことができる。
hdmi2usb

講演者のプレゼン表示用ノートパソコンの外部出力をHDMIに繋ぐと、それを会場用プロジェクター出力とサブTVにHDMI出力でき、また、中継用にビデオカメラ映像と合成してUSB出力することができるというものなのです。

この製品の利点
・プレゼン表示画面とビデオカメラ映像の合成はHDMI2USBボードで行うので中継用パソコンの負荷軽減
・UVC(USB Video Class)の機器として認識されるため専用ドライバが不要
・firmwareは公開されているためカスタマイズ可能(Xilinx Spartan-6の知識が必要)
・Ubuntu環境がプライマリサポートで、Ubuntuのみで中継配信までを行える

現状、HDMI2USBのハードウェアは「Digilent Atlys」と「Numato Opsis」の2種類があります。

「Digilent Atlys」はXilinx Spartan-6の汎用ボード「Digilent Atlys」として市販されている汎用ボード使用したプロトタイプです。
それに対して「Numato Opsis」は、今回のプロジェクト用にカスタマイズされたものとなります。
Numato Opsisは、いまはまだ開発中であるもののDisplay Portの入出力ができるようになるらしいので、今後を考えるとこちらの方がいいんでしょうね。安いですし。

なお、HDMI入力をUVC(USB Video Class)として入力出来るようにするだけであれば「パソコンやスマホにHDMI入力をつけてビデオカメラの生中継に使う方法」でも可能です。

中華液晶ペンタブレットHUION向けの液晶保護フィルムのサードパーティー品が販売開始


中華液晶ペンタブレットHUION向けの液晶保護フィルムとして販売してるのは、いままで純正品ぐらいでしたが、Amazonでの取り扱いはなく、直販ぐらいでした。

が・・・いままでワコム向けでいろいろ液晶保護フィルムを出しているメディアカバーマーケットから、HUION向け商品の販売が開始されました。

タイプは下記の3種類
・廉価な「ペーパーライク 反射防止 タイプの 液晶保護フィルム」
・多機能な「ブルーライトカット 指紋防止 反射防止 抗菌 気泡レス 液晶保護フィルム」
・保護最優先「キズが付きにくい! 強化ガラス同等の高硬度 9Hフィルム」

HUIONタブレットは、ワコムと比べるとペンにより傷つきやすいところがあるため、フィルム無しはつらいところがあります。
国内発送で素早く届くようなので、選択肢としてはよいのではないでしょうか?
