#U 关于Gnome中的nautilus问题
by Tony Wei
环境：Fedora, Gnome, nautilus文件管理器
问题：在浏览网页时，当将网页“另存为”时，通常会得到一个 example.html 文件和一个对应的文件夹 example_files
，这两者是一对。在Windows中，当复制（或剪切）example.html 到 PATH 文件夹中时，example_files
也会同时被复制到 PATH 中。但是在上述 Fedora
环境中，却并不会两者同时被复制，而是需要对两者分别进行复制操作才行，这通常会发生这样的问题――只将 example.html
文件复制到了某处，而忘了同时将 example_files 文件夹也复制到某处，再打开 example.html
时，发现丢失了不少东西，例如网页上的图片等。
请问在 Fedora 中，应该如何解决这个问题，使得对 example.html 与 example_files
中的任何一个进行复制（或剪切）操作时，另一个会自动得到同样的操作。

Fwd: dist-git project update
by Liang Suilong
dist-git 应该会伴随 F14 的到来而到来的。cvs 系统就要说再见了。

Subject: dist-git project update
To: devel(a)lists.fedoraproject.org
It's been a while since I last updated folks on dist-git, and in reality
it's been a while since I last worked on it. Fedora 13 took up all my
time.
Since my last update we've made great progress on fedpkg, the new tool
that will replace the make system. It is packaged up with
fedora-packager and has the ability to do many tasks that our Make
system handled. Here is a quick list:
build
chainbuild
clean
clog
clone
compile
gimmespec
install
lint
local
mockbuild
new
new_sources
prep
scratchbuild
sources
srpm
unusedpatches
verrel
Many of these targets take optional arguments which extend their
functionality and replace some other specific Make targets. This list
is enough to get us checking code out and in, and building in koji.
On the koji front we've recently discovered the changes necessary to
build from dist-git style repos, and those changes are being polished up
and committed upstream. We have done multiple builds successfully from
dist-git repos.
Where do we go from here?
We're ready for more wide scale testing, and to facilitate that I am
refreshing the git repos from current CVS (people with existing clones
will have to blow them away and re-clone), and getting a koji stage
instance up that we can build against (with limited builders). We'll
then push out another fedora-packager update that has the right URLs to
build against this stage Koji and announce that it is ready for
building.
Based on this testing, and some decisions around git tagging and branch
usage, we stand a good chance at being able to roll this out prior to
the F14 branch event. I hope you are all as excited as I am about this!

#U 有用mutt的吗？问个关于多账户的问题。
by Liberty
我用mutt邮件客户端已经好长时间了，但是有个问题困扰了我很就。
就是如何根据Header里的From 自动设置SMTP服务器。比如Gmail用的是一个，
学校里面又是另一个。 根据mutt的帮助有:
If additionally you have to use different SMTP-servers depending on the
From-addr, then have a look at /Sendmail, too.
但是我没有找到相关的例子。试着用send-hook但是不太管用。
有人知道如何配置吗？谢谢！

#D MySQL 5.1.47 InnoDB 插件性能提升
by Liang Suilong
这篇文章介绍了 MySQL 5.1.47 里使用内建的 InnoDB 与 InnoDB 的插件之间的性
能差别。两者性能可谓天翻地覆。我一直以为 built-in 的话，应该会有更好的优
化，而且内部通信之间的延时也会降低，从而在性能上有点优势。但是恰恰相反的
是在这个测试。是不是这个插件从 MySQL 5.5 中把 InnoDB 的特性 backport 出
来的呢？
刚好 Fedora 12/13 的源里都是 MySQL 5.1.47 这个版本，大家可以留意一下。

Sent to you by liangsuilong via Google Reader: Performance gain of
MySQL 5.1 InnoDB plugin via Planet MySQL by Giuseppe Maxia on 6/6/10
You know already that InnoDB in MySQL 5.5 has great improvements in
performance and scalability. You will have to wait a few months for
that, though, because MySQL 5.5 is not GA yet.
But if you need some extra performance in MySQL 5.1, you may want to
use the Innodb Plugin instead of the built-in one. As of version
5.1.47, the Innodb plugin is of GA quality, and it comes with a good
out-of-the-box improvement compared to the built-in engine.
To test my assumptions, I used one of my test Linux servers to perform
a sysbench on 5.0.91, 5.1.47 built-in and plugin, and 5.5.4. The MySQL
servers were all configured with
innodb_buffer_pool_size=5G
MySQL 4.1.47 was tested both as out-of-the-box, and with the plugin
enabled.
ignore_builtin_innodb
# note: the following statements must go all in one line
plugin-load=innodb=ha_innodb_plugin.so;innodb_trx=ha_innodb_plugin.so;innodb_locks=ha_innodb_plugin.so;innodb_lock_waits=ha_innodb_plugin.so;innodb_cmp=ha_innodb_plugin.so;innodb_cmp_reset=ha_innodb_plugin.so;innodb_cmpmem=ha_innodb_plugin.so;innodb_cmpmem_reset=ha_innodb_plugin.so
default-storage-engine=InnoDBinnodb_file_per_table=1
innodb_file_format=barracudainnodb_strict_mode=1
The test was the same for all the servers. A simple sysbench both
read-only and read/write on a 1M records table.
sysbench \
--test=oltp \
--oltp-table-size=1000000 \
--mysql-db=test \
--mysql-user=$USER \
--mysql-password=$PASSWD \
--mysql-host=$HOST \
--mysql-port=$PORT \
--max-time=60 \
--oltp-read-only=$ON_OFF \
--max-requests=0 \
--num-threads=8 run
What came out is that, by using the innodb plugin instead of the
built-in engine, you get roughly 15% more in read-only, and close to 8%
in read/write.
Note that 5.5. enhancements are more impressive in scalability tests
with more than 8 cores. In this server, I have just tested a simple
scenario.
I did some more testing using "ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=X"
in the InnoDB table, where X changed from 4 to 16. But sysbench didn't
seem to play well with compression. For low values of KEY_BLOCK_SIZE,
you actually get a much worse result than the built-in engine. I have
yet to figure out how I would use this compressed InnoDB in practice.
