Bought a MacBook Air (Middle 2011) - 11inch, US Keyboard, 4GB Memory, 128GB SSD and Core i7 - to replace my MacBook (Early 2008) that has served me very hard as a Vine Linux development environment as a daily basis for a few years.

To be honest, I always have used my whity MacBook with Vine - Mac OS X is always there on the harddrive in a separated partition, but I seldom booted it up on my MacBook - maybe once or twice a year? Another OSX machine at home, an old PowerMac G4 MDD, is still there and serving me as a daily basis as well, to store my huge digital music contents (almost all in lossless format) on iTunes (still hundreds of CDs left to get ripped though), and as a scanning machine (connected to the old SCSI A3 flatbed scanner).

The first thing I did on my new toy was to play around the new OS for a while that amazed me a bit. This was the first time for me to play with the multi-touch trackpad and gestures. I felt Gestures and "Mission Control" are really great for portable computers with small screens like this MBA 11inch.

And the next thing I gonna do was, of course, to figure out how well this brand new machine is supported on Linux - I know there are so much to get done on the Linux kernel, the X thing, and some userland utilities, to run Linux on the MBA 2011 flawlessly, but I just thought it was worth checking out and playing around.

Create Lion Recovery On Your USB Flash Drive

So you are going to try installing Vine Linux on your MacBook Air (Middle 2011) which doesn't come with any recovery media. Of course, if you have a wireless connection to the Internet, you will be able to restore OS X Lion through the net, without any install media. This is called “Internet Recovery”, built into newer Macs starting with Mac Mini (Middle 2011) and MacBook Air (Middle 2011).

But you should be fully prepared - “Providing is preventing” - you would be happier to have the physical recovery medium, an USB flash drive, that contains OS X Lion Recovery, before facing some accidental issues.

All you need is an USB flash drive and Lion Recovery Disk Assistant. Create the USB flash drive recovery media before installing Linux for safety.

In case you already build up your own environment on OS X Lion, you would better back up your whole system with Time Machine - this will simplify the process of restoring your entire OS X environment onto the specific partition of your harddrive.

Boot up the Linux Installer, partition the drive, then install

Now you are nearly ready. Prepare another USB flash drive and make the USB install medium. If you already have Linux machines, connect the flash drive to the machine, identify the device name (such as /dev/sdb) very carefully, then just do this:

$ sudo dd if=Vine60-x86_64-DVD.iso of=/dev/sdb

(or alternatively)
$ sudo sh -c 'cat Vine60-x86_64-DVD.iso > /dev/sdb'

Similarly you can create the USB install medium on Windows machines, using DDforWindows or Image Writer for Windows.

CAUTION, PLEASE NOTE: Unfortunately a nasty bug is found on Vine Linux 6.0 x86_64 edition, that will cause some issues, when trying to install onto the harddrives with GPT partition table. The bug is already fixed (among the Vine developers) and will be released as a part of future releases of Vine Linux. 32bit edition does not suffer from this issue. You would install the 32bit edition instead, or wait for the minor fix version of the x86_64 edition.

Shut down your MacBook Air, plug the USB flash drive, hold the option key while pressing the power button, then you will see the boot selector named “Startup Manager” that is built in Intel Macs. Select the USB flash drive and press return, and the initial screen of Vine Linux Installer would appear.

Be sure to select NOFB MODE before proceeding - otherwise your MBA will black out and will “hard freeze”. The KMS (Kernel-based Mode Setting), Intel Framebuffer driver and Xorg driver on Vine Linux 6.0 (even on breeding-edge Linux kernel and Xorg as of today) is NOT compatible with the 2011 MBA hardware yet.

Then the Vine Installer starts. As my MBA is brand new and I already have Recovery USB flash drive, so I don't hesitate to erase all the partition on the MBA SSD. If you already have your own OSX Lion environment, you would back up your whole OSX system with Time Machine as noted far above.

The only thing you should keep in mind is, place the Linux partitions first, then the OS X partition. This is a limitation of the GRUB bootloader (unless you use newer GRUB2 bootloader), as it only sees the MBR partition tables which can hold up to four partitions. OS X on Intel Macs, on the other hand, relies on the GPT (GUID Partition Table) that can hold more partitions. As long as you use the GRUB bootloader, Linux partitions (especially the / partition or /boot partition which holds Linux kernels and initrds) must be either of first four partition.

My case - I know MBA 2011 is not fully supported on Linux yet (and hopefully several months needed to get fully supported), so I decided the Vine Linux directly on MBA 2011 was just for testing purpose. 10GB for /, 2GB for swap, the rest (approximately 107GB) kept free to reinstall OS X later.

Did a few settings (selecting languages, keyboards, timezone and a few more) in the Vine Installer, then finally the installation process starts. As the MBA comes with a SSD harddrive, package installation itself is faster than you could imagine - just a few minutes - not long enough to grind coffee beans and drip brew. You would try instant coffee when installing Linux on machines with SSD.

Okay, you finished installing Vine Linux. But you need a few more to do. Otherwise the Linux system you just installed won't boot.

Reinstall OS X (or Restore your OS X system from Time Machine)

Next, you need to reinstall OS X. Boot from the Restore USB flash drive, open Disk Utility, and create the HFS+ partition while keeping the Linux partitions intact. Then proceed restoring OS X. Alternatively you may restore your OS X system from the Time Machine backup onto the HFS+ partition you just created.

Install rEFIt

You are just one step away from the completion. Boot up the OS X you just reinstalled/resotred, grab rEFIt, then install.

Then open the Terminal, and type the following command.

$ cd /efi/refit
$ sudo ./enable.sh

Okay, now you are almost done. Reboot your MBA. If you did everything correctly, you will see the rEFIt boot selector.

But don't rush - you have one more thing left to do - syncronize GPT and MBR tables. On the rEFIt screen, use arrow key to select “Partitioning Tool” (gptsync) then press return. Press Y to syncronize the GPT/MBR partition tables. Then shut down your MBA once for safety.

Then you'll be able to boot into the Vine Linux, finally.

Current Status: Vine Linux 6.0 / VineSeed on MBA 2011

Unfortunately, as I already noted far above, there are still so many things to get done on the Linux kernel, the X thing, and some userland utilities, to run Linux on the MBA 2011 flawlessly. You will see many restrictions on Linux (not only Vine but also many other distros) on MBA 2011, at least AS OF AUG. 16, 2011.

Vine Linux 6.0 doesn't fully support MBA 2011, while VineSeed (development version of Vine Linux) gradually supports MBA 2011 features - see the updates below.

(1) (Vine Linux 6) You'll need to add nomodeset to the grub.conf. Otherwise your MBA will hard-freeze during bootup.
UPDATE: (SEP. 6, 2011): most recent VineSeed (kernel-3.0.4-1vl7) doesn't hard-freeze w/o nomodeset. However, you need Apple Mini DisplayPort (ThunderBolt) / DVI (or HDMI) Adapter to get the screen. Without nomodeset, the screen will only appears on the external display (built-in LCD will get blank).
UPDATE: (SEP. 16, 2011): most recent VineSeed (kernel-3.0.4-2vl7) finally supports 1366x768 resolution on the built-in LCD. Now no need to add nomodeset to the grub.conf.

(2) (Vine Linux 6) X still can't do 1366x768. 1024x768 at most, strangely stretched wide.
UPDATE: (SEP. 6, 2011): with recent kernel and without nomodeset described above, you get normal 1024x768 on the external display. Intel HD Graphics can do 3D accelaration (w/ xorg-x11-drv-intel-2.16.0-2vl7) and compatible with GNOME Shell.
UPDATE: (SEP. 16, 2011): with recent kernel (3.0.4-2vl7) and without nomodeset described above, you finally get 1366x768 on the built-in LCD display, featuring 3D acceleration with GNOME Shell.

(3) Wireless network works out of the box - with kernel-module-compat-wireless package installed (on Vine6), or with kernel-3.0.1 (VineSeed).

(4) Sound output is initially muted, so you need the following tasks:

• Execute alsamixer.
• Press the F6 key, and unmute the “Surround” or the likes. Press ESC to exit.
• Execute sudo alsactl store to save the setting.

(5) FaceTime Camera is properly recognized by Linux kernel with uvcvideo.

(6) Special keys, such as LCD backlight control (F1/F2), keyboard backlight control (F5/F6), sound mute/volume control (F10/F11/F12) does not work at all. The pommed will treat them like a charm on old MacBooks and MacBook Pros (or even some PowerBooks and iBooks), but unfortunately the pommed is not compatible with the new MacBook Air (Mid 2011) yet.

(7) As this is a Mac, there is no middle-click and right-click - you'll need to enable mouse button emulation to handle this. There are two ways to accomplish the mouse button emulation - one is sysctl way and and the other is Xmodmap way. Please search over the Internet as there are plenty of pages on this.

(8) UPDATE: (SEP. 16, 2011): at least with most recent kernel (3.0.4-2vl7) on VineSeed, suspend/resume works flawlessly on my MBA Mid2011 11-inch.

Installing Vine on VirtualBox Instead

So the status of Vine Linux 6.0 on MBA 2011 for desktop purpose is still far from flawless (although there's a notable progress going on with the development version, VineSeed, as described above). But I have my old MacBook 2008 that runs VineSeed rock solid, and I have spent my daily computer life on this. I bought my MBA to replace my old MacBook.

That's why I decided to create rather small Linux partitions (10GB for /) on the SSD, keeping the OS X partition approximately 90% of its original size. I mean, sometimes (or very frequently) I may want to try if Linux (as of today) runs good on MBA, but too early to spend every minute on this.

So what did I do?

We have another (and very easy) way to install Linux on Intel Macs - VirtualBox (not VertualBox, but VirtualBox - to whom it may concern). I mean, I install Vine Linux on a VirtualBox running on OS X Lion. I know there is yet another way - a similar solution - VMWare Fusion, a famous commercial product. But this time I go with VirtualBox as I've been already familiar with running VirtualBox on Vine Linux - testing Vine installer, using other Linux distributions for certain purposes, et al.

The installation itself is really a piece of cake. And you'll get the Linux running on a virtual machine like a charm. You don't have to worry about hardware compatibility issues. You can quickly let your Mac sleep by closing the lid, while Linux is on a virtual machine - no matter what that Linux is compatible with sleep or not. You can run Linux on full-screen mode (although VirtualBox is not OS X Lion's ‘Full-Screen’ App yet) with 1366x768 resolution very quick and fast. You can instantly switch from OS X (host OS) and Vine Linux (guest OS) by swiping the trackpad with your three fingers - give another huge round of applause to Mission Control!

This is “insanely great”, actually. Two Vine Linux developers (daisuke & munepi) bought MBA 2011 as well, and they do this way. They didn't ever tried to install Vine directly onto their MBAs like I did this time.

But in the meantime I will keep looking for some hacks and upstream fixes that will make Vine Linux running directly on newer Intel Macs flawlessly like it already does on my old whity MacBook. This is why I still keep small 10GB Linux partition on my MBA 2011's SSD.

Okay, so I need to move my current Vine environment on my MacBook to the VirtualBox on OS X Lion - hope it will not take long - and I gotta say to myself, installing Linux on MacBook Air is just the means of restoring my daily environment, not an end in itself (except when I am debugging and developing Vine Linux itself).

カセットのウォークマンやCDウォークマンを携帯してヘッドフォンで聴きながら外出していたのも遠い昔の思い出。もうここ10年程は、外出中にヘッドフォンなどを使って音楽を聴くこともなくなりました。

外出中は、世界中の生音を聞いてる方がよっぽど楽しいですからね。

静寂、喧騒、機械や車両の動作音、世間話、客寄せサウンド、虫や鳥や犬や猫のたてる音、赤ん坊の鳴き声、子供たちの元気な会話、殺伐とした空気感、耳なり、風の音、自分の鼓動、その他もろもろ。

PCや携帯音楽プレーヤでまともに音楽を聴くことがほとんどなかった私にとっては、 Last.fm Scrobbler なるものはほとんど意味をなさなかったわけですが、まあこれで自家用車運転中に聴いた音楽を scrobble することはできるようになりました。scrobble すること自体が（自分にとって）どれだけ意味があるのかは分かりませんが (笑)

で、問題の Last.fm Scrobbler for Mac。iPod scrobble がまったくといっていいほどまともに動いてくれない。

先日バグ修正バージョンとして 1.5.4.26864 なるものがリリースされましたが、これもまだおかしい。iPhone でたくさん再生したとして、そのうち最後の数曲分しか scrobble されません。

ソース 見て直したろか、という程、Last.fm Scrobbler がないと困ってるわけでもなし。

というか、せっかく 3G 回線や WiFi 回線で接続されてるんやから、iPhone 本体から直接 scrobble できたらそれでええんちゃうんかなあ。

と思ったのが今朝の運転中。帰宅後、なんとなく App Store をぱらぱら見てたら、なんか素敵っぽいものを発見。iScrob ですと。無料。

使い勝手は基本的に iPod アプリと同じです。ふつーに聴く分にはなんも変わらんといっていい。

違うのは、これで再生中にオンラインで Last.fm に scrobble してくれるということ。ネットワークがつながらないときは、つながるようになった時にまとめて scrobble してくれます。

そして、バックグラウンド状態で操作する際（ホームボタンをダブルクリックして右にスライドしたら出てくる画面）でも、通常の iPod アプリを奪って iScrob が居座っているのが更にナイス。完全に iPod アプリの代替として機能してくれています。

Thanks David Patierno-san for such a nifty iPhone app - it's just what I have been looking for! Definitely a perfect replacement for the in-stock iPod application!

後日談（2010/08/12）：
今のところ唯一の大きな不満。iPod app を完全に override しているわけではないので、iScrob で再生時、ドックコネクタ経由での再生トラック情報は正しく出力されていません。よって、iPhone/iPod をドックコネクタ経由で USB 接続などしてコントロールするオーディオセットやカーオーディオユニット側には、再生中の曲のタイトル・アーティスト・アルバム名、および再生ステータスなどは一切表示されません。代わりに、iScrob 動作中には裏で止まっている iPod app のステータス（例えば「STOPPED」など）が表示されます。

恐らく同様の技術的理由により、iPhoneロック時にも、ロック画面に再生中トラック情報は表示されません。

これが現時点で実装されていない（やりにくい）のには、いろいろと技術的（もしかしたらSDKの契約的?）な問題があるのかもしれません。JBしたScrobbleでは以前から実装していることのようですが。

開発者の David Patierno さんに聞いてみたところ、「ドックコネクタ経由で楽曲情報が出ていない件は、技術的には、ロック画面に曲の情報やアルバムアートが表示できないことと関係していそうだと感じる。現時点での制約上では難しそう。iOS 4.1 になってそれが可能になっていれば嬉しいし、可能になり次第 iScrob に実装するつもりだ。」とのことでした。

後日談（2011/02/12）：
もうひとつ、致命的な不満を見つけてしまい、 結局、iScrob の使用をやめてしまいました。残念。

iScrob で再生しても、再生履歴情報（再生回数、最終再生日時など）がライブラリには一切反映されない、というものです。これは、iScrob が iPod app とは別個のアプリケーションであることや、実装の方向性からくる制約といえるのかもしれません。

やはり、再生そのものは iPod app にまかせて、再生情報だけうまいことバックグラウンドでひろったり Last.fm に scrobble したりしてくれるものがあれば、それに越したことはないのですが。そのためだけに JB するというのも。。。

結局いまは、再生は普通の iPod app で、scrobble 自体は Mac 上の scrobblepod にお任せすることに。これで、iPod app の使用感そのままに、再生情報はきちんと保ったまま、Last.fm オフィシャルプラグインで頻発していた iTunes での sync 時のイライラ (考えられない程遅い、ちゃんと scrobble してくれない) からも解放されることになりました。

最初は exiftool を叩いていたんやけど、数百枚の画像取り込みとかだとリネームが卒倒しそうなくらい遅すぎるので、MacPorts 使って exiv2 を入れることに。シェルスクリプトから叩く程度の安直さであれば、まあこの辺りが手をかける限界かなと。

手元のマシンが G4 MDD Dual なので Leopard どまり。ということで Xcode 3.1.4 をとってきて入れたのちに sudo port install exiv2 で準備完了。

# exiv2 は MacPorts で入れてるので path を追加
export PATH=${PATH}:/opt/local/bin

# exiv2 が見つからなければ終了
if ! which exiv2 2>&1 > /dev/null ; then
        exit 1
fi

for f in "$@"; do
        # EXIF にキー Exif.Photo.DateTimeOriginal が含まれている場合のみ
        if exiv2 -Pk "${f}" | grep -q Exif.Photo.DateTimeOriginal ; then
                DIR=$(dirname "${f}")
                ORIG_FILE=$(basename "${f}")
                # 既に日付がファイル名に含まれている場合はいったん削除
                NEW_FILE=$(echo "${ORIG_FILE}" | sed "s/\([0-9]\{8\}_\)\([0-9]\{6\}_\)*//")
                if [ "${ORIG_FILE}" != "${NEW_FILE}" ] ; then
                        if [ -f "${DIR}/${NEW_FILE}" ]; then
                                mv -f "${DIR}/${NEW_FILE}" "${DIR}/backup_${NEW_FILE}"
                        fi
                        mv -f "${DIR}/${ORIG_FILE}" "${DIR}/${NEW_FILE}"
                fi
                # EXIF データに基づいてファイル名を変更
                exiv2 -r'%Y%m%d_%H%M%S_:basename:' rename "${DIR}/${NEW_FILE}"
        fi
done

Automator ワークフロー上で「写真をダウンロード」の代わりに「選択された Finder 項目を取得」にすれば、既にディスク上に取り込んでいる画像ファイルのリネームにも使えます (が、肝心の「選択された Finder 項目を取得」自体が激遅なので、素直に Terminal からスクリプトを実行するのがいいかと)。

いまどきはファイル名なんかは気にせずに、Picasa などで閲覧・管理というのが主流なんでしょうが、まあなんとなく。適当に手抜きで。
