[Update] Me, a speaker and photographer at FUDCon APAC 2014

It's my first time attending FUDCon, the second time meeting community members.
I don't live Tianjin anymore so it's impossible for me to get the place earlier. To make sure that I can attend the event successfully, I booked train tickets 20 days before.
It's already 10:40 when I arrived at the meeting place. Then I completed the registration and looked around to know what to do next. The volunteers are so busy there, so I decided to take some pictures for them first.
When I came into the main meeting hall, Jiri Eischmann and Jaroslav Reznik's speech - Fedora.Next: Features and Friends was near to the end. I stood at the back of the room and tried to find any acquaintance to chat. But it's so difficult, cause everyone was facing to the stage.
When Robert Mayr talked about Fedora Websites in the 8th meeting room, I found out that he is Robyduck and Robyduck is him. I can see his nickname every time when I update the website translation on Transifex. But we've never met before.
During the tea break in the afternoon, many people gathered in the lobby and chatting. Some of them met for the first time, some of them are old friends. Everyone enjoyed the event. I tried to chat with someone, but didn't know what to talk about, so I just held the camera capturing this great event.

At the end of the ROS on Fedora by Ankur Sinha, I proposed to Alick to take a group photo for the volunteers and speakers in the 8th meeting room. While other audiences left for the main meeting room, two guys were still on their seats talking something. I invited them to join the group photo also, but they refused. May be they thought that neither were they speakers nor volunteers in the room, or other reasons. Then they left.

I had supper with Alick Zhao, Tommy He and his friend, Liang Suilong joined us later. We chatted for the whole evening. It was near 0:00 when Alick and I came back to the hotel.

I shared room with Wei Fu from Redhat, his speech was about Fedora on ARM. There was a problem with my Fedora 20, it won't mount my camera. Wei Fu then helped me copied photos out of my camera and tried to solve the problem.

The second day morning was rather interesting to me. I met Tobias, two from Gnome doc team(I will tell you who they are) and Arch user Alexander on breakfast. I think Toby, yes, Tobias Mueller, might feel weird when I asked him "May I know your name?". You know that he gave the first keynote speech on main hall the first day morning. Every one should know his name. But I missed it as I mentioned above, I was late.

When I came back to the hotel again to check out, I met one of the guys who didn't want to take the group photo in yesterday again, and I said "Hello" to him. I still didn't know him until he went to the stage of main hall to give a speech on systemd: A perspective for systemd: What has been achieved, and what lies ahead. Yes, yes, he is Lennart Poettaring.

I promised to Alick that I would take photos for the event. So my main task beside my own speech, was to capture interesting scenes. I couldn't focus too much on each speech at the same time while my eye was viewing from viewfinder. But it's lucky that there will be a video for each speech, so I can watch them later.

After systemd, more audiences shown up in the main hall. They were waiting for their hero, Richard Matthew Stallman. He gave me a very deep impression with his humor throughout his speech. He spoke in a relatively slow speed so that everyone can understand him. At the end of his speech, he auctioned his book and a stuffed baby gnu. When the highest bidders paid for the book and gnu, I came to the stage and tried my best to capture everything. That was the first action of a photographer I think.

RMS's speech was little longer than scheduled, so it's only 20 or 30 minutes left before the afternoon speeches began after we came back from lunch. Robert Li from Redhat talked about i18n and L10n test day at first. Meanwhile, I powered on my computer to check and prepare my presentation. I decided to use Chinese to introduce my topic at last.

I had 16 pages slides and two demos. My original plan was to introduce the slides first and make an interactive live demonstration, if time was not enough, then I would play the demos instead. Time ran very fast, I even didn't come to the last slide, the volunteer notified me that there was only 10min left. I had to skip the rest of the slides and played the demos directly. The amount of audiences was not out of my expectation, about 20 or less. This may because that most of the audiences were developers, or interested in developing.

After the speech on oVirt by Li Jiansheng, I left the 8th meeting room for the lobby. There I took some group photos for our community members Alick, Christopher Meng, Gerard and Duhongwei. Then the girl from Gnome doc team, who I met on the morning asked me if I want a sticker. She gave me one, one, another one and rest two, five in total. Yes, yes, she is Kat. It's so kind of her and David. I told them that I am the translator of Fedora Project and also the translator of GNOME. But most of my work(about 99.9%, haha) are contributed to Fedora. The main meaning she said to me was that it will be good even only one line of translation is contributed, and it will be great if more than one string are contributed. They also shown their interests on Chinese tea, and said they would have a tea shopping. So I suggested them to find one who knows Chinese tea very well as a guide.

I had to leave the event for the railway station before the closing speech and continue to work on next day. But my thought was still there, recalled everything happened and expected to the next meet.

Thank you to the guys who made this event happened in China.
Hope you will like the photos taken by me.

[Update]
About photos:
I've set all the photos taken by me(except the photos of Richard Matthew Stallman) to some-rights-reserved, CC-BY-SA on Flickr. However, due to the internet speed and condition I have, I didn't upload the photos in their original size. They are half-size JPG file. If you like a photo and want to download it, you can contact me for the bigger size one, even RAW file. The raw files are so big(7.1G) and it's difficult to store online, but I will keep it as long as possible on my computer.

/boot 分区被删掉了怎么办？

/boot 分区被删掉了怎么办？

这个真的是在我办公室电脑上发生了。当时正常开机，等待引导系统时，却发现直接进入了 grub 命令行 grub>
我顿时感到惊奇，哪里出了问题？不过还是试着加载内核，但是输入 (hd0,5) 后提示错误。按 tab 键出来的备选分区也少了一个。
我试着引导 XP，

grub>rootnoverify (hd0,0)
grub>chainloader +1
grub>boot

还好，XP 正常引导，看来不是硬盘的问题。从 XP 中查看了分区结构，/boot 那个几百兆的分区神奇的被删除了。到现在我还是没有找到被删的原因。
既然如此，那就每天输入命令进 XP 吧，反正工作也需要它。
前言到此结束。
直到昨天，我决定把我的 Fedora 修好。
按照自己的假设，应该重建 boot 分区然后挂载，把内核镜像还有 grub 相关文件放进去，就可以了。当然前提是要能建立删掉的分区才可以。XP 下是没指望，还是用万能的 rescue 模式吧。
我没有 rescue 光盘，也不打算为此刻录一张（太浪费资源了）。在此向您推荐 bfo[1] 或 bko[2]，关于这两个的介绍可以参考我之前写的kickstart 和 BFO 引导自动安装 Fedora[3]。
现在进入恢复步骤：
1. 从带有 bfo 镜像的 U 盘启动计算机，通过 bfo 进入 rescue 模式；
2. rescue 模式会找到硬盘上已有的 Linux，然后按提示进入 shell；
3. 为了方便，在进入 shell 后执行 chroot /mnt/sysimage/；这样可将找到的 Linux 系统的根目录设为当前 shell 下的根目录；
4. 执行 #fdisk /dev/sda，然后按 p 列出当前分区表结构，以保证稍后建立分区时不会出错。如果你非常地熟悉自己的分区结构，可忽略这个操作；
5. 按 n 键，新建分区，我的 /boot 之前处于扩展分区，因此这里还是选择扩展分区（l），然后设置分区起止位置，如果跟我一样，硬盘只剩下之前 /boot 那么点空白空间的话，那直接使用默认值就可以。如果您的硬盘空白空间很大，并不打算都用作 /boot，那就小心一点，根据您的需要进行调整；
6. 完成新建分区后，按 p 键你也许会发现分区顺序有所改变。例如我新建的分区就成了 /dev/sda7。这时我们可以按 x 进入 expert mode，然后按 f 键，重新调整分区编号顺序，使得分区编号与分区所在物理位置对应，修改后新建的分区编号为 /dev/sda6；
8. 完成以上步骤，并确认没有错误后，按 w 键保存分区表，退出 fdisk。
重新启动计算机，再次进入 rescue 模式，重复 1-3 步，
9. 然后执行 #mkfs.ext4 /dev/sda6，在新建的分区创建 ext4 文件系统；
10. 修改 /etc/fstab，将新建的分区挂载到 /boot；
11. 重新安装引导程序和内核：
执行 #grub-install /dev/sda 重新安装 grub
运行 #yum update kernel 安装最新的内核
12. 如果这时已有 /boot/grub/grub.conf 文件，那么就可以直接重启完成修复；否则要是像小弟我，装完 grub 没有 grub.conf（我怀疑是我先安装内核后安装 grub 造成的）文件，那就需要自己动手写一个了（这个过程略掉了）。好在我之前保存过一个备份，直接改改复制到了 /boot/grub/ 下，好了，重新启动；

一切正常，/boot 重建成功，大功告成。

手动升级 Fedora 12 中的 Firefox-3.5 到 Firefox-3.6.13

Fedora 12 已经没有 Firefox-3.6 的更新了。虽说 Firefox 下载解压即可使用，但是为了方便就尝试把 3.6 的文件放到 /usr/lib/firefox-3.5/。也许这真是多此一举 :)

1. tar xjf firefox-3.6.13.tar.bz2 # 解压生成 firefox 目录

2. rsync -rvu firefox /usr/lib/firefox-3.5/ # 使用 rsync 其实是为了更新 /usr/lib/firefox-3.5 中已有文件，不过参数没有正确，把以前没有的也更新进去了。其实这样还不如直接 cp

3. 同样的方式有 rsync 了 /usr/lib/firefox/plugins，还是不如直接 cp；mv /usr/bin/firefox /usr/bin/firefox.bak;cp firefox/firefox /usr/bin/firefox，

4. bash 下运行 firefox，这时错误就出现了，找不到 lib 文件目录。解决也很简单：vi /usr/bin/firefox # 修改里面的 moz_libdir="更新后 firefox lib 文件目录"，也就是 /usr/lib/firefox-3.5
其实就是因为 lib 的目录位置问题

5. 再次运行 firefox，崩溃掉。log details 显示与两项 adds on 有关；

6. bash 运行 firefox -safe-mode，禁用掉 adds-on，这回可以了。在安全模式下禁用有问题的 adds-on，重新启动 firefox，更新 adds-on。

是个有些麻烦的过程。:)

孩子们发给我的

via 我爱张兮兮 by keyan6829 on 7/26/10

从上海回来看到了我们班孩子们转发给我的这封邮件。上学期我们观看了《海豚湾》，现在，他们当然不会对这件发生在小美人鱼、安徒生的故乡的事件保持沉默。虽然他们的声音很渺小，但是，能够张开眼睛去关注世界，是一件多么重要的事情。所有的保留中世纪的愚昧、落后的所谓传统都要向文明转变，更何况是屠杀。

利用 Kickstart 和 BFO 自动安装 Fedora

前言

kickstart 是 Redhat 开发的一个系统自动安装方案。它可以用来自动安装 RHEL 以及 Fedora。采用 kickstart，用户只需建立一个配置文件，将安装过程中所需的操作（如分区方案、软件包信息、引导程序等等）写入文件，安装程序即可按照该文件进行自动安装。详情请见：kickstart wiki 页面 [1]。

BFO 是随 Fedora 13 带来的一个新的安装方式，基于 BKO（http://boot.kernel.org），它通过网络运行安装程序并进行操作系统的安装。BFO 的镜像文件很小，本身不足 1MB，而且几乎无需更新。只需从 bfo.iso 引导，即可安装你想要的 fedora 版本。不过，前提是你要有网络连接。详情请参考：bfo [2]。

准备工作

1. kickstart 文件，在你用常规方式安装完系统后会在 /root/ 目录下保留一份 anaconda-ks.cfg，如果想要按照你当前系统的设置来自动安装，不妨直接使用该文件。

注意：系统安装通常都是通过光盘或其它介质安装，安装源都位于本地。为了配合 bfo 安装，需要对生成的 kickstart 文件中的安装源做下修改。

此外，也可以使用 GUI 工具 system-config-kickstart 来生成。当然如果你熟悉 kickstart 文件格式的话，可以直接编辑一个。
1.1 下面我以我虚拟机上的一份 ks.cfg 为例，对 ks.cfg 做个简单介绍。

#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Firewall configuration
firewall --enabled --service=ssh #防火墙开启，ssh为信任服务。
# Install OS instead of upgrade
install #全新安装
# Use network installation
url --url="http://download.fedoraproject.org/pub/fedora/linux/releases/12/Fedora/i386/os/"
#如果使用本地安装后生成的 kickstart 文件，那么就要添加这个选项。
#该选项指定了网络安装时安装文件的位置。
#它的目录结构必须跟光盘中的结构完全相同。
# Root password
rootpw --iscrypted $1$jsonnTig$f7b4NFqCj2UBr.4bfrkH.0 #root用户密码，已经过加密处理
# System authorization information
auth --useshadow --passalgo=md5
# Use text mode install
text #如果不指定 text，那么默认会使用图形安装方式
# System keyboard
keyboard us # 这个是键盘布局，使用 us 键盘
# System language
lang en_US # 系统语言
# SELinux configuration
selinux --enforcing #selinux 选项
# Do not configure the X Window System
skipx
# Installation logging level
logging --level=info
# Reboot after installation
reboot
# System timezone
timezone Asia/Shanghai #系统默认时区
# System bootloader configuration
bootloader --location=mbr #引导程序安装位置
# Partition clearing information
clearpart --all --initlabel #分区选项，clearpart --all 即清空所有分区，--initlabel 表示初始化磁盘
%packages #软件包选项
@base #我的虚拟机配置太低，而且是通过网络安装，因此只选了最基本的包
%end

以上就是一份简单的 kickstart 文件内容，更多的选项可以参考 Fedora 文档 [3]中的 Fedora 安装指南，或者 Kickstart的wiki页面 [1]。

2. bfo 镜像文件，这个文件可以直接到 bfo下载页面[4] 下载，我这里使用了光驱镜像文件，bfo.iso。如果你用实体机安装，建议还是用 USB 的镜像比较好，不到 1MB 的小东西，刻张盘太浪费了。
3. 网络连接
这个是必须的:)

安装

1. 首先从含有 bfo 镜像的设备启动，我这里的虚拟机就是用虚拟光盘引导了。引导界面如下图：

2. 通过 bfo 文件引导后，将进入如下的画面：

3. 选择第二项，Install Media，按回车键；
4. 接下来将看到类似如下图片的屏幕：

5. 这次安装的是 32位的 Fedora 12，选中后按 Tab 键，编辑引导选项。

在最后，我们加上 linux ks=http://my.example/ks.cfg，这指定了 kickstart 文件的位置。ks 文件的位置可以为本地，也可以为网络。这要根据具体情况办了。详细参数还是请看 kickstart 的wiki吧。
6. 添加 ks 文件位置后，按回车，自动安装就此开始了。如果 ks 文件配置正确，网络连接正常，过一会我们就可以使用我们的新系统了。
