11:11:14 # Life 朝気づいたら昨晩しこんでいたmencoderのジョブがおちていて， 録画に失敗していた． 再度パッチを作成，これで改良することを祈るが，多分関係無い． 2.6.14がリリースされてから，bttv関連のパッチががんがん来ているので， おそらく誰かがメンテナンスをのっとって改変しまくっているような気がする．

下記のパッチを適用することで，自分のカードのオーディオは認識する． 動作は確認していない．

mencoderを実行した際に， frameno.aviが見付からない，というエラーは毎回でていたのだろうか．

xawtvは正常に動作するので，mencoderのバグかもしれないと思い， とりあえずアップグレード． marillatレポジトリの 1.0-pre7cvs20050716-0.1 を1.0-pre7cvs20051102-0.0 にあげる． 同じようなエラーが出て，録画ができない．困った．

11:19:18 # Life pbuilder のアップロード． 0.137． いくつかの修正とドキュメントのアップデート．

12:22:40 # Life aliothでcvs commitのあとにメーリングリストでdiffを送信するようにするには どうしたらよいか． 既存では，/usr/bin/cvs-mailcommitとsyncmailの両方が使われているようだ． commitinfo にDEFAULT /usr/bin/cvs-mailcommit --mailto メールアドレス --from 送信元 --diff --full --root %r --dir %p %{sVv}と書くらしい． 1.12 以降のCVSでは仕様が変わったらしく， --root と --dir が必要になった．

13:37:54 # Life OracleをDebian-amd64にインストールする． Faheem Mithaがこの苦しみに挑戦しているらしい． バイナリしか配布されていないアプリケーションをDebianにインストールするのは結構難しい． 特に，Debianのamd64ポートはbiarchではなく，pure64ポートなため， 64bitを中心に構築されている． Oracleのバイナリはほとんどの部分が32-bitで構成されているらしい． そのため，32-bitのライブラリを多数要求してきて，Debianではなかなかインストールしにくい という状況だ． 64-bitと32-bitの話題については，先日のgotomさんの発表に詳しい． Debianで，Oracleを使えないのはそれなりに痛い． しかし，いままでも正式にサポートされていたか，と聞かれるとさらに痛い． そこ，つつかないで．．．
