飞信虽然在linux下已经有libfetion和linux-fetion for purple了，不过都没有直观的纯CLI操作方式。找来找去只找到个闭源的飞信机器人，这软件优点是:纯命令操作，简单快捷。

不爽的地方是:

1. 闭源，依赖的库文件有版本要求。而且从主页来看，商业味比较浓，怕有猫腻
2. 初次运行后会生成数个当前用户无访问权限的文件夹，强行删除再运行又会重新生成

唉，我又开始二了，用人家的东西还这么多牢骚。下面是实现方法：

在此处下载飞信机器人的linux版，运行程序依赖的库文件有4个:libcrypto.so.0.9.8, libssl.so.0.9.8, libACE.so.5.6.8, libACE_SSL.so.5.6.8。前两个属于openssh，后两个可以# emerge dev-libs/ace得到，鉴于版本问题和libACE 8MB的体积问题，还是直接下载它提供的库文件包吧。

建议解压后放到自己的$HOME目录下，例如我把它解压到$HOME/fetion-cli下，把解压的4个库文件也放到此目录下。

飞信机器人支持config文件读取帐户信息，创建一个$HOME/.fetion-cli.conf，按以下格式输入你的帐户信息:

# ID    Mobile          Password
1        你的手机号码   你的飞信密码

然后是建立一个bash脚本fetion-sms.sh

#!/bin/bash
#usage: fetion-sms.sh MobileNum. ENTRY
 
cd /home/punkid/fetion-cli
LD_LIBRARY_PATH=. ./fetion --config=$HOME/.fetion-cli.conf --index=1 --to=$1 --msg-utf8="$2"

这个脚本用法很简单，输入$ sh fetion-sms.sh 接收方的手机好码 飞信消息内容就完成了。

所以在aMule的Download completed event里配置如下就行了:

sh /home/punkid/scripts/fetion-sms.sh 你的手机号码 "%NAME 下载完成"

这回算是比较满意了，飞信接收速度快而且不像GCal那样分两条不完整短信发过来。

思索了下，最好的通知方式莫过于短信，而真正可用的免费短信功能莫过于Google Calendar的短信通知了。由于aMule本身就有Events功能，剩下的唯一问题就是能在linux下执行的Gcal CLI了。好在为Google做的third party的大有人在，很快就找到了Gcalcli这个python客户端，连ebuild在Gentoo Bugzilla上都有了。

gcalcli的用法很简单，先在$HOME目录下创建一个.gcalclirc文件，里面写入以下几行:

[gcalcli]
user:yourname@gmail.com
pw:yourpassword
cals:all

写法无须解释，最好至少给chmod 600 .gcalclirc下，毕竟密码是明文的，给别人看到就糟了。

然后新建一个download-notify.sh的文件，写入如下几行:

#!/bin/bash
#usage: download-notify.sh FILENAME
 
NOTIFY_TIME=`date --date='+5 min' +%R`
FILENAME=$1
ENTRY="$NOTIFY_TIME $FILENAME download finished"
 
gcalcli quick "$ENTRY"

这是用来快速添加Google Calendar事件的脚本，设定时间是当前时间的5分钟后(给予一定时间差的容错值免得短信还没来得及通知就已经成历史事件了)，文件名将由aMule的Events传递。

接下来要做的是进入Google Calendar设置默认的通知方式，先确保你开通了短信通知功能，然后进入Settings -> Calendars标签页 -> Notifications，将默认通知方式设置为1分钟前短信通知。

剩下的就是aMule设置的问题了。进入Preferences -> Events，在Event types里选择Download completed，有两个可供执行脚本的input框，第一个是当aMule Core发现下载完成时执行指定命令，第二个是仅当aMule GUI发现下载完成时执行指定命令。不管你使用aMule daemon还是aMule GUI，第一个是绝对可行的。所以开启第一个并输入类似命令sh ~/scripts/download-notify.sh "%NAME"。

OK，可用了。短信通知还是蛮及时的，唯一不爽的就是Google非得分两条未满短信通知我。

有了gcalcli能做的事就多了，例如电脑一旦发现sshd遭受brute force attacks时立刻短信通知，对网管应该比较有用吧 :)

I’m using Amarok via libgpod-0.6.0 to manage my iPod library, there’re approximately 1,000 songs of 68 albums in my iPod. As I checked the iPod_Control/Artwork directory of my iPod, it took up unexpectedly +300mb for the cover images.

punkid@Genbox /media/MUGELLO/iPod_Control $ du -h Artwork/
314M    Artwork/

Then I tried iTunes to rebuild my music library, the artwork database shrinks to 53mb.

punkid@Genbox /media/MUGELLO/iPod_Control $ du -h Artwork/
53M     Artwork/

As someone in that post pointed out:

it turns out that iTunes isn’t actually storing one piece of artwork per track or even one per album – in my case at least, it stored one cover for only 2 of the tracks on the 12-track album …

Fortunately this issue has been fixed in the libgpod svn version, and the new artwork database size looks quite impressive. It’s even smaller than the iTunes’ one.

punkid@Genbox /media/MUGELLO/iPod_Control $ du -h Artwork/
18M     Artwork/

The latest libgpod svn build has already supported the new iPod Nano 4G, and the photo issue also seems to be fixed. If you dont have the patience for a “never-landed” new stable release, grab the latest libgpod svn snapshot.

For Gentoo users, you may put the media-libs/libgpod-9999.ebuild into your personal ebuild repo.

Note : I removed the doc USE flag from the ebuild due to the latest libgpod somehow needs gtk-doc to make distcheck to work correctly. Bad news, KDE fan boys :(

• Tips in Aggregate (1)

I initially used git to sync my .vimrc file and my own ebuild repo, but it is not cost-efficient as I actually pay little attention to the tracking commit things. So I ended up using rsync to synchronize my linux files to my dreamhost account.

Preparation

Assuming you’ve already had a dreamhost account with shell access priviledge (any other hosts with shell access will be fine as well). And you’re going to backup the following files on your system to the dreamhost server:

/home/yourname/.aliasrc
/home/yourname/.bashrc
/home/yourname/.config/openbox/
/home/yourname/files/
/home/yourname/.vimrc
/home/yourname/.vim/
/home/yourname/.xinitrc
/home/yourname/.Xdefaults
/etc/fstab
/etc/fonts/local.conf
/etc/make.conf
/etc/portage/package.*
/etc/X11/xorg.conf

Ofc you dont want others to see your loveletter.txt and bankaccount.txt under files directory, so the two files should be excluded from synchronization.

Put the following two lines into a textfile (such as ~/.rsync/excludes) which we’ll use it later:

/home/yourname/files/loveletter.txt
/home/yourname/files/bankaccount.txt

Howto

I wrote this script for sync:

#!/bin/bash

includes="
/home/yourname/.aliasrc
/home/yourname/.bashrc
/home/yourname/.config/openbox/
/home/yourname/files/
/home/yourname/.vimrc
/home/yourname/.vim/
/home/yourname/.xinitrc
/home/yourname/.Xdefaults
/etc/fstab
/etc/fonts/local.conf
/etc/make.conf
/etc/portage/package.*
/etc/X11/xorg.conf
"

rsync -avzuCRpP --delete --delete-excluded $includes --exclude-from "/home/yourname/.rsync/excludes" -e ssh USERNAME@HOSTNAME:linux/

The $includes contains the files you want to sync, * wildcard supported, and to exclude the private files you’ll need the --exclude-from paramater.

USERNAME@HOSTNAME is your dreamhost account and hostname, :linux/ means sync the files to the linux directory under your dreamhost home directory.

-a parameter makes sure your files will be synchronized recursively.

-C is used for ignoring files like .git, .svn, *.bak and so on, ofc we dont want to waste time on transfering these useless things.

-R is needed for transfering hierarchically, this means I can sync my /etc/make.conf file right under linux/etc/ directory on my dreamhost.

-P parameter is quite useful when the transaction is interrupted, you can continue the process somewhen later.

Now you can chmod +x scriptname before you run it first time.

Fetch the backup files from your dreamhost is easy, just to run:

rsync -e ssh -av USERNAME@HOSTNAME:linux/ backup/

The files will be transfered to the backup directory on the local computer.

You may need the Password-less SSH Login if you want to add this script to the cron job.

I use this cron job to make sure the script run automatically at 23:30 p.m. on every Monday and Thursday.

30 23 * * 1,4   punkid   sh /home/punkid/scripts/autobackup.sh

Douban and PHP

按照之前QQ签名秀的原理把豆瓣的个人广播系统也给提取出来了，效果请见此test页面。

使用方法是把以下代码添加到你的页面里:

<script type="text/javascript" src="http://punkid.org/glade/douban/request.php?userid=<strong>username</strong>&numbers=5"></script>

其中userid后面跟的是你的豆瓣用户名，numbers后面是显示条目数(最多10条)。至于怎么polish这个douban的miniblog纯粹是你的CSS活。对了，输出编码是UTF-8。

PHP tips: 用addslashes这个函数可以对字符串进行转义。

Linux

1. Tired of emerging the world?

emerge $(eix -Iuc --format-compact "<category>/<name>" dev-libs/* | head -n -1)

可以用来更新某一category(例如dev-libs)下的已安装软件。

2. Ape转mp3

emerge shntools 和 mac-port (gentoo-china overlay提供) 后运行:

shnsplit -f filename.cue -t "%n - %t" -o "cust ext=mp3 lame --preset extreme - %f" filename.ape

会根据cue文件对ape进行切割成按tracknumber - trackname命名的mp3文件，不过ID3信息没法保存进去，交给Musicbrainz搞定吧。

3. 使用Aria2下载器

原来用的axel不知何故在我的电脑上经常出现Initialing download就停滞不前的情况，无奈…换了个稍微大点的Aria2。顺便把Gentoo Mirror的默认下载也换成了aria2。更改make.conf如下:

FETCHCOMMAND="/usr/bin/aria2c -c -s 4 -d ${DISTDIR} -o ${FILE} ${URI}"
RESUMECOMMAND="${FETCHCOMMAND}"

至于在firefox里用flashgot启用aria2下载，在Executable path里填/usr/bin/rxvt (任意虚拟终端，别用xterm就是了，那个启动太慢了)，然后在Command line arguments template里填-e aria2c -s 5 -d [FOLDER] [URL]

WordPress

1. 只显示当日评论数

不明白我的意思的，留个言在到首页看下就知道了，当日有留言的日志会格外用类似于3 comments today方式显示。方法很简单，抽数据而已。修改你的模板的index.php，再最顶端添加:

<?php 
	$nowtime = current_time('timestamp');
	$today = date('Y-m-d G:i:s', mktime(0, 0, 0, date('m',$nowtime), date('d',$nowtime), date('Y',$nowtime))); 
?>

然后是修改loop部分:

<?php if (have_posts()) : ?>
	<?php while (have_posts()) : the_post(); ?>
 
		<strong><?php $today_comments = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments WHERE comment_post_ID = $id AND comment_date >= '$today' AND comment_approved = '1'"); ?></strong>	
		<div class="entry"
		<h2 id="post-<?php the_ID(); ?>" class="entrytitle"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
		<p class="metadata clearfix">
		<strong><span class="cmt"><?php if ($today_comments > 0) { ?><a class="todaycmt" href="<?php the_permalink() ?>#comments" title="Comment on <?php the_title(); ?>"><?php echo $today_comments; ?> Comment<?php if ($today_comments>1) echo 's'; ?> Today</a><?php } else { ?><?php comments_popup_link('No Comments', '1 Comment', '% Comments'); ?><?php } ?></span></strong>
		</p>
		...
		</div>
 
		<?php } ?>
 
		...
 
<?php endif; ?>

加重部分是关键。

2. 过滤某category的feed输出

在模板的function.php里添加这段代码:

<?php
function RssFilter($query) {
     if ($query->is_feed) {
         $query->set('cat','-<strong>22</strong>');
     }
         return $query;
}
 
add_filter('pre_get_posts','RssFilter');
?>

其中22为你的category ID。

CSS

CSS的代码书写风格我倾向于单行式，用缩进表明元素的从属关系。例如:

#secondary div.modules {margin-bottom:40px;}
	#secondary div.modules a {color:#888;}
	#secondary div.modules a:hover {color:#FF32B3;text-decoration:underline;}
	#secondary div.modules h3 {color:#94C742;border-bottom:1px dotted #94C742;}
	#secondary div.modules ul li {padding:3px 8px;border-bottom:1px dashed #FF80D0;}
	#secondary div.modules ul li:hover {background:#F0F8E2;}
 
#bottom_wrapper h3 {color:#FDF262;border-bottom:1px solid #FDF262;}
	#bottom_wrapper div.modules {width:300px;margin:0 10px;float:left;position:relative;display:inline;}
	#bottom_wrapper div.modules ul li {height:1.6em;padding:3px 2px;border-bottom:1px dotted #528F08;overflow:hidden;}
	#bottom_wrapper div.modules ul li:hover {background:#528F08;}
	#bottom_wrapper div#misc table.calendar {width:300px;margin-bottom:20px;border-collapse:separate;border-spacing:1px;}
		table.calendar td {padding:3px 0 2px;text-align:center;}
		table.calendar td.calendar_h {display:none;}
		table.calendar td.today {background:#528F08;}
		table.calendar td.week {background:#528F08;color:#FDF262;}
	#bottom_wrapper div#tags ul li {margin-right:5px;padding:0;display:inline;border:0;}	
		#bottom_wrapper div#tags ul li span, #bottom_wrapper div#tags div {display:none;}

也许这种单行的方式不利于阅读，但是类似block的书写方式最大的问题是一旦CSS代码上个几百行的，要找到某一行翻页是件很痛苦的事，而单行定义加上适当的缩进即便不看HTML源代码也能对页面结构有个基本的认识。还有就是…在VIM下用w,b进行整词跳跃是件很惬意的事，即便是单行也能很快的跳跃到需要修改查看的property。

English

1. take with a pinch of salt

Radiohead的A Wolf at the Door里有句歌词是Take it with the love its given, take it with a pinch of salt, take it to the taxman。

那take it with a pinch of salt真的是抓把盐吗? 真实的意思有点类似于姑且相信，半信半疑的意思，例如Regarding what you said yesterday, I would take it with a pinch of salt意思就是你昨天说的那些我姑且相信吧。

Tia Dalma and I go way back

在电影Pirates of the Carribean : The Man’s Chest (加勒比海盗2:聚魂棺)，Jack船长带着众人去找女巫Tia Dalma时说: No worries, mates. Tia Dalma and I go way back.。我记得当时我看的思路的版本翻译成了伙计们，别担心，Tia Dalma和我待会就回来。这其实是错误的，go back way的意思是表示两人认识很久了，交情很好。

I bought myself an iPod Nano (Product)^red by the end of last year, it was cool. But the biggest problem i confront is how do i manage my iPod music library and sorts of things under Linux, since I’m a linux daily-user, i merely switch back to my Windows XP system. What’s more, i really DISLIKE using the iTunes under Windows, it’s just not so handy to me, as well it costs too much memory. So, with Google’s help, eventually i found some good solutions to make my iPod work under Linux. And here comes the guide, i’ll break it down into several sections, enjoy it!

Note: I’m using Gentoo linux, and KDE DE, but i presume things will be much even easier if you’re using the Everyone-Loves-It (k)ubuntu linux distro (I’ll make some notes below each paragraph, letting you ubuntu users know what to do)

Preparation

Before you get any further, first you need to install libgpod, that’s the core component to make iPod work under Linux. In Gentoo linux, you can simply run emerge libgpod, but please ensure that you’ve already added the gtk USE if you want to make the coverflow work, which i’ll explain later. So run USE="gtk" emerge libgpod is a good choice.

Note: What if you’re using (k)ubuntu? Dont worry about the Gentoo USE things, just run apt-install libgpod or some sort of that command (Sorry, I dont have ubuntu installed so i really have no idea the exact package name for libgpod)

To make my iPod automounted, i enabled hald and dbus service, and the KDE itself will handle the rest. Put the hal dbus into your make.conf‘s USE, and emerge the hal and dbus.

# echo "sys-apps/hal acpi disk-partition" >> /etc/portage/package.use
# emerge hal dbus

Then run emerge -auvDN world to make everything work with dbus and hal. Or you prefer using eix --installed-without-use hal and eix --installed-without-use dbus to manually check the packages which need re-emerge. After that, lets start ‘em.

# /etc/init.d/dbus start
# /etc/init.d/hald start
 
if you prefer starting them when booting your system, just
# rc-update add dbus default
# rc-update add hald default

Note: The Ubuntu users can totally ignore what i mention above about the hal and dbus, since Ubuntu has already done these all for you, i said things will be much even easier :)

Music Library Management

This is the most important part, the software we need is Amarok, a multimedia killer app, which is also the best music player AFAIK. To make it work with iPod, lets first do the USE things :)

# echo "media-sound/amarok ipod" >> /etc/portage/package.use
# emerge amarok

1. Identify Your iPod

Once you get the hal work, the iPod device should be auto mounted (the default path is /media/ipod by udev rules), at least under KDE. Launch your amarok, and switch to the ‘Device’ tab, and identify your iPod model under ‘Set iPod Model’.

2. Transfer Music

Now you can easily ‘drag n’ drop’ your mp3s into the ‘Device’ tab container, or you can right click the files/albums/playlists to choose ‘Transfer to Media Device’

The next step is simply click ‘transfer’, copy the mp3s into your iPod.

Note: It’s supposed to have your music appeared in your iPod if you installed >=libgpod-0.6.0. But what if your iPod (The Classic or Nano 3G, or iTouch) doesnt show any items you’ve transfered? Then we need to get our hands a little of dirty :)

Run lsusb -v | grep -i Serial with root privilege, and copy the 16-character-long hash string (something like 00A27001301221F) into the clipboard. Then open the /media/ipod/iPod_control/Device/SysInfo file with your favorite text editor, append this line into it:

FirewireGuid: 0xffffffffffffffff

Replace the ffffffffffffffff with that 16-character-long hash string you just got.

3. Cover Flow Effect

Coverflow effect is really fascinating, you can easily fetch the album art cover from Amazon via Amarok.

To make sure your iPod recognize the coverart setting in Amarok, simply click the ‘Update Artwork’ under ‘Device’ tab, that’s all, i say THAT’S ALL :D

Tip: If you have some V.A albums, you may find it quite disturbing when you flip the cover flow, seeing the same album image several times under different artist names. And they’re all pointed to the same album! To group ‘em under Various Artists, just go to the Amarok’s ‘collection’ tab, right click the album and choose ‘Show under Various Artists’, then re-upload the album to your iPod. Or you can choose ‘Do not Show under Various Artists’ if you think the artist name does matter.

Video Management

With Amarok, you can also simply drag n’ drop the video files (mov, mp4) into your iPod, you dont need to worry about which directory they’re supposed to be placed.

So what i’d demonstrate here is how to convert the AVI movie file into your iPod MP4 file, and how to get the youtube video into your iPod.

1. Deal with AVI Movie File

What i want to deal with the avi movie file is to get a scaled clip video with only a few minutes which’s suitable for iPod playing, as well i’d also like to embed the subtitle into the clip due to my poor English understanding :D With Mplayer’s mencoder, everything turns out so easy.

Make sure you at least have these USEs enabled for mplayer. We need <Code>encode</code> use to build mencoder support, and those vedio and audio libraries for encoding.
 
# USE="aac win32codecs xvid encode mp3 quicktime srt" emerge mplayer

Here is the command we’re gonna run: (based on bones7456′s nautilus toiPod script)

$ mencoder -ss 00:36:36 -endpos 00:01:35 \
   -of lavf -lavfopts format=mp4 -oac lavc -ovc lavc \
   -lavcopts aglobal=1:vglobal=1:vcodec=mpeg4:vbitrate=600:acodec=libfaac:abitrate=128 \
   -af lavcresample=24000 -vf dsize=320:240:0,scale=0:0,expand=320:240,harddup -ofps 25 -srate 22050 \
   -sub "subtitle.srt" \
   input.avi \
   -o output.mp4

Yeah, i know these commands seem too complex, let me break ‘em down into detailed explanation.

1. The -ss means the starting timeline, with-ss the -endpos means shifting forward time. In conjuction, this line -ss 00:36:36 -endpos 00:01:35 means we’re gonna start record the clip from 00:36:36 to 00:38:11 (36:36 + 01:35 = 38:11)
2. The second, third and the fourth lines make sure the encoding meets the iPod spec requirement. If you have a larger screen like iTouch, iPod, change the 320:240 to 480:320.
3. And we use -sub "subtitle.srt" to embed to subtitle into the clip
4. The last line of the first command specifies the output filename

If you find the command too complex to recall, you can save the following script to /usr/bin/toIpod, and make sure it has the execute priviilege (chmod a+x /usr/bin/toIpod)

#!/bin/bash
#Copyright (c) 2008 bones7456 (bones7456<A>gmail<D>com)
#Modified by puNk!d
#License: GPL
#version 20080911
 
SAVEDIR="/home/media/video"
 
INFILE="$1"
PWD=`pwd`
CMD="mencoder -of lavf -lavfopts format=mp4 -oac lavc -ovc lavc "
CMD+="-lavcopts aglobal=1:vglobal=1:vcodec=mpeg4:vbitrate=600:acodec=libfaac:abitrate=128 "
CMD+="-af lavcresample=24000 -vf dsize=320:240:0,scale=0:0,expand=320:240,harddup -ofps 25 -srate 22050 "
if [[ -f "${INFILE%.*}.srt" ]];then
	CMD+=" -sub ""\"$PWD/${INFILE%.*}.srt\""
elif [[ -f "${INFILE%.*}.ssa" ]];then
	CMD+=" -sub ""\"$PWD/${INFILE%.*}.ssa\""
elif [[ -f "${INFILE%.*}.ass" ]];then
	CMD+=" -sub ""\"$PWD/${INFILE%.*}.ass\""
fi
 
CMD+=" -o ""\"$SAVEDIR/${INFILE%.*}_ipod.mp4\""" ""\"$PWD/$INFILE\""
eval "$CMD 2>&1"

Now you can run toIpod videofile to convert the video into mp4 file which is stored in /home/media/video, and it will automatically embed the subtitles if the sub file has the same name as the video file.

Note: The credit of this script goes to bones7456, I only did some small modification to deduct the gnome dependency (zenity tool).

2. Save Youtube Video into Your iPod

Here comes another scenario, I’d like to save the youtube video Tech Talk: Linus Torvalds on git into my iPod so i can watch it before sleep. We can achieve this with youtube-dl and FFmpeg. If you dont have ‘em yet, just emerge ‘em!

# emerge youtube-dl ffmpeg

Make sure your ffmpeg compiled with at least aac, encode, win32codecs USEs.

Then we can obtain the youtube flv video file by:

$ youtube-dl "http://www.youtube.com/watch?v=4XpnKHJAok8" -o output.flv

And use ffmpeg to convert it into mp4 file.

$ ffmpeg -i output.flv -acodec libfaac -ac 2 output.mp4

Transfer the output.mp4 with Amarok, its done!

Note: As Michel pointed out, if you’re sick of the endless CLI, try Avidemux, a GUI tool does make life easier in some cases :D

Scrobble iPod Play History to Your Last.fm

Amarok has last.fm built-in support, so whenever we play the music, the songs will be scrobbled to our last.fm account automatically. And the exciting thing is, Amarok can also handle iPod play history!

Just check the ‘Synchronize with Amarok statistics’ under ‘Configure Media Device’ dialog window. Then plug in your iPod, you can see the submit queue from Amarok status bar if there’re some tracks unscrobbled.

Transfer Photos into Your iPod

I use Gwenview as my first-choice photo management software on KDE, some of KDE users prefer Digikam. Whatever, it doesnt matter. Cuz they both support Kipi Plugins which we need to deal with iPod photo transfer.

Install Gwenview and Kipi-plugins with iPod support: (For ubuntu users, just get the gwenview and kipi!)

# USE="ipod" emerge libkipi kipi-plugins
# USE="kipi" emerge gwenview

Then we can see the ‘Export to iPod’ option under ‘Plugins’ -> ‘Tools’ menu in Gwenview.

Note: After some investigation and test, I found unfortunately there was no software perfectly delivered the photo transfer function. As kipi-plugin, libpod fails to show up the original picture on iPod whilst gpixpod produces a blank n’ black thumbnail. Read the discussion from here.

Note 2: As Thomas pointed out, there’s a patch for libgpod to fix the thumbnails problem. Follow the patch here: gtkpod with ipod nano 3g

Extras

Here comes the extra things part on iPod, we got Calendars, Contacts and Notes extras on iPod, but we dont feel like to deal ‘em with iTunes. How come we need to do the simple note with a 50mb+ memory cost multimedia software :(

1. Notes

It’s quite easy actually, just put the text files into the /media/ipod/Notes directory, that’s ALL.

2. Calendar

iPod uses Mac’s iCal calendar file, but we dont have Mac, and neither we have iTunes. But we can use some third-party software like Ximian Evolution or Mozilla Sunbird under Linux, nonetheless, personally i’d like to use some web apps to deal with the iCal file. Google Calendar is definitely my 1st choice.

Choose one of your calendars, and click the ‘Calendar Settings’, in the bottom of the setting page, we see the iCal banner in ‘Private Address’, just save it to the /media/ipod/Calendars directory.

3. Contacts

iPod supports vCard to implement its Contacts function, and we can use Gmail to generate the vCard file
(C’mon, you should at least have a Gmail account unless you’re a Yahoo! die-hard fan :D )

I’m gonna save my words on howto do add contacts under Gmail, this is not the part of this iPod-related guide. To export the Gmail contact list into vCard file, click the ‘Contacts’ link in Gmail page, then choose to export it with vCard format, save it to your /media/ipod/Contacts directory.

END

That’s all what i can tell you guys, if you have any other tips on iPod under Linux, feel free to share with us.

And, i know there’s a software named gtkpod which can deals with iPod media synchronizing and photo transfer. But i dont feel like to recommend it, IMHO, its just not so handy as Amarok and Gwenview. Anyway, you might prefer using it if you’re using Gnome :)

主要症状是这样的: 使用华硕K8N4-E/Deluxe主板的，无论是使用Gentoo LiveCD 06/07版还是自编译内核(>2.6.13)启动，都无法识别到SATA硬盘设备，必须采用降级内核的方式或者使用Gentoo LiveCD 2005才能正常识别，而在Ubuntu/Fedora Core (2.6.2系列kernel)下却没有这个问题。只要是大于2.6.13的内核无论是gentoo-sources, genkernel, vanilla-sources, mm-sources, sabayon-sources甚至Ubuntu和Fedora的kernel都没用。我曾经在论坛里发过帖子询问，当时没太在意，以为降级内核到2.6.13就算解决了，但是随便kernel的不断更新，问题越来越多了，udev不能用最新的，与之而来的就是hal不能自动挂载移动储存设备，nvidia驱动不能用100系列版本，否则退出X会花屏，xorg-x11不能用7.3，因为没有100系列的nvidia驱动配合，这么多问题差点让我被迫转投ubuntu了，还好最终还是选择向Gentoo Community寻求帮助。

我在open a new thread之前就发现论坛里用同样一块主板的朋友都遇到了这个问题:

1. SATA drives not recognized on kernel > 2.6.11
2. Problem finding my SATA-drives
3. kernel panic (solved)
4. What does “VFS: Cannot open root device…” mean, exactly?

加上后面两个我之前发布的贴子/回复，搜集好所有信息后，我发了个新的帖子:

Kernels(>2.6.13) dont recognize sata disk on K8N4-E [solved]

并给当时发表/回复那些帖子的人发了封private message，也得到了这些人的热心帮助，但是始终没能解决问题。于是我去Gentoo Mailing List上发邮件，也没能得到解决的办法，最终选择了向Gentoo的Bugzilla提交bug，直接询问Gentoo Developers。

Bugzilla Bug 194531 : Kernels (>2.6.13) dont recognize the sata harddisk on ASUS K8N4-E motherboard

在这里得到了解决方案，关闭MMCONFIG PCI Access Mode可以成功识别到SATA设备，正如其中一个developer说的: Nforce motherboards don’t have the best history with the linux kernel。关闭MMCONFIG有两种方式，一是设置内核:

取消自动选择模式和MMCONFIG模式，选择BIOS或者DIRECT方式

CONFIG_PCI=y
# CONFIG_PCI_GOBIOS is not set
# CONFIG_PCI_GOMMCONFIG is not set
CONFIG_PCI_GODIRECT=y
# CONFIG_PCI_GOANY is not set

二是在grub.conf的kernel行末尾添加pci=nommconf参数来关闭它。

同样，使用Gentoo LiveCD的话，可以在启动时加入启动参数nommconf来顺利引导LiveCD读取SATA硬盘。问题是解决了，不过查看下ubuntu和fedora的kernel config文件，并没有关闭MMCONFIG模式，难道还是Gentoo的问题?

在Developers的帮助下，进入Kubuntu/Fedora LiveCD，cat /proc/iomem发现其中没有那句f0000000-f3ffffff : PCI MMCONFIG 0，意味着Ubuntu和Fedora把MMCONFIG给blacklist了。哪位使用Ubuntu或者Fedora的朋友麻烦把cat /proc/iomem的结果贴出来给我看下，我想知道是Ubuntu/Fedora直接blacklist了MMCONFIG还是在硬件检测时根据我的硬件关闭了MMCONFIG。

这样，整个症结就落在了MMCONFIG上，排除了Gentoo本身的因素。

Gentoo之所以受青睐的原因不仅是它的高度可定制性和portage的包管理方式，还有它背后强大的社区支持。Gentoo的官方论坛 是目前最活跃的linux论坛之一了，里面集结了来自全世界各地的顶尖linux高手和geek，无论是帖子还是回复都是高质量的，即便是不用Gentoo Linux的朋友在里面都能找到很多有价值的东西。而Bugzilla作为forum的补充，提供了与开发人员直接的交流平台，你可以得到最专业的帮助。

I <3 Gentoo and its Community !

使用eix来检索你的portage

Gentoo的Portage越来越庞大了，平常使用命令emerge -s package来查找软件包实在是要等很久。建议安装eix，它通过检索portage来实现包的快速查找，而且检索功能十分强大，连overlay的包都能找。

eselect is powerful

eselect 是个非常方便的工具，有了它不用再手动给gentoo-sources做/usr/src/linux链接了，不用再为更新profile而重做make.profile的链接了。使用#eselect 查看有多少modules可以使用。然后输入#eselect module-name list来查看该module的属性。例如我要查看我的profile:

# eselect profile list
Available profile symlink targets:
  [1]   default-linux/x86/2006.1
  [2]   default-linux/x86/no-nptl
  [3]   default-linux/x86/no-nptl/2.4
  [4]   default-linux/x86/2006.1/desktop *
  [5]   default-linux/x86/2007.0 
  [6]   default-linux/x86/2007.0/desktop
  [7]   hardened/x86/2.6
  [8]   selinux/2007.0/x86
  [9]   selinux/2007.0/x86/hardened

其中带*号的表示这是我当前使用的profile，现在我想更改为最新的2007.0/desktop。显然我不想再使用冗长的#ln -s /usr/portage/profiles/default-linux/x86/2007.0/desktop/ /etc/make.profile命令了，利用eselect我只需要输入#eselect profile set 6 就行了。再如更改内核链接，先用#eselect kernel list 查看当前/usr/src/linux链接指向何处，再通过#eselect kernel set * 来重新设置就行了。

用parallel-fetch 边emerge边下载

新装一个Gentoo或者要emerge一大堆软件包要花费大量时间，而其中不少时间还是消耗在下载上的，利用parallel-fetch 可以一边emerge一边以后台方式帮你下载需要的软件包。只要在/etc/make.conf里添加如下这句就行了:

FEATURES="parallel-fetch"

Control the USE flags with EUSE

gentoolkit 里自带的euse是个非常实用的小工具，利用它可以查询相关的USE flag信息，例如#euse -i kde。同时，我们还可以利用#euse -E kde和#euse -D kde在make.conf中分别添加或删除kde的use flag。

用qlop 查看你的emerge记录

portage-utils 里带的qlop可以用来查看你的emerge log以及当前正在emerge的软件包和消耗时间。例如#qlop -c 来查看当前正在emerge的软件包，用#qlop -tH package-name 来查看过去emerge该软件包的耗时。

用远程主机提供的ssh做代理

有国外主机并能够使用ssh的朋友可以使用#ssh -qTfnN -D 9050 用户名@主机名 命令来与远程主机建立tunnel实现端口转发，然后只要在firefox里的代理设置里，把http代理地址设置为127.0.0.1，端口为9050就可以实现那远程主机做代理上网了 ( 参考文章《利用Putty通过ssh端口转发实现FireFox和MSN加密代理访问》 )。

另外，在DH主机的论坛里翻了下，DH主机商的态度是默认允许使用ssh做代理的，但不公开推荐 :D … 说白了就是放心的用吧! 只要你不拿它乱下非法东东。

让vim自动识别中文编码

GB18030/BIG5编码的文档在vim下显示为乱码怎么办?
在.vimrc下加入这句set fileencodings=ucs-bom,utf8,GB18030,Big5,latin1就行了。

!$ or Esc + .

$ unzip /home/media/audio/mp3/blur/blur-13.zip
 
假设我们解压完某压缩包后，现在要删除该压缩包文件，我还需要输入后面那一大串路径吗? 我们可以利用!$来代替，它表示最后一条命令的最后一个参数。现在我们只需要这样了
 
$ rm !$

或者可以不输入!$，而是按下Esc键再按下 . 键就可以了，它会自动替你补充上条命令的最后一个参数的。

Linux无法识别你的新设备

你的硬件实在太新了，linux无法识别怎么办? 运行#update-pciids 来下载最新的设备信息吧。

使用希网的动态域名

我想在自己的电脑上架主机，可我没有固定IP怎么办? 我也没有自己的域名…先去希网注册个免费的二级域名，然后根据它提供的动态解析功能，使用lynx来刷新域名所绑定的IP地址。

#lynx -mime_header -auth=用户名:密码"http://www.3322.org/dyndns/update?system=dyndns&hostname=你的免费域名"

OK，可以通过你所注册的免费域名访问你在自己电脑上架的主机了。欢迎各位互架主机交流音乐，电影!
