很多西方媒体发现，对破坏圣火行为的厌恶，把很多华人团结了起来。《时代》周刊网站说，与以往不同，这次海外抗议奥运火炬传递活动激起了中国人大声疾呼要团结一致。旧金山一名华人妇女在网上写道：“从现在开始，我们是为自己而战。我们知道是祖国变得更加强大后使得西方世界感到害怕，是我们的发展和自信使他们感到恐惧。从某个方面来说，通过这次奥运火炬传递，一种新的价值观已经形成，所有中国人再次走出来团结在了一起。”
美国《基督教科学箴言报》说，几十年来，华人社区在旧金山已大致分为两派———大陆人和台湾人，来自台湾的华人在传统上对北京持否定和批评态度。然而这一次，包括来自台湾的许多美籍华人，都支持北京奥运、谴责那些人权抗议活动，这反映了在华人心中，基于民族自豪感的力量压倒了政治上的分裂。
虽然我不是狭隘的民族主义者，不是愤青，但我真的很喜欢看到这些，让人很感动。曾经下过决心，如果有一天当我们要干掉小鬼子时，我愿意捐献我所有的钱，然后上战场帮战士们扛子弹。
There’s a new version of InnoDB 5.1 available:
The early adopter release of InnoDB Plugin for MySQL is available for MySQL 5.1 and later, in source and binary (for most platforms) and is licensed under GPLv2. Users can dynamically INSTALL the InnoDB Plugin to replace the built-in InnoDB within MySQL 5.1 Linux and other Unix-like operating systems (and soon on Windows) without compiling from source or relinking MySQL. (For now, Windows users must re-build from source.)
Nice… check out this feature set!
Fast index creation: add or drop indexes without copying the data
Data compression: shrink tables, to significantly reduce storage and i/o
New row format: fully off-page storage of long BLOB, TEXT, and VARCHAR columns
Hi there!
I arrived at Santa Clara yesterday, just in time for the MySQL Community dinner (check this post on Arjen’s blog). It was a lot of fun, not to mention the opportunity to talk to developers and other folks from MySQL/Sun.
Unfortunately, I forgot to pack in my luggage a card reader or a proper cable for my camera, so pictures will have to wait a few days. To mitigate this problem, I’ll try to hunt down more posts from other guys, but in the meantime, you might want to check the 2008 MySQL Users Conference & Expo group at Flickr.
Yesterday was the “Tutorials Day”. I’ve been to many of them. The subjects were so interesting I just couldn’t stay put for the whole session so, I kept jumping from one to the other. A few quite interesting sessions: MySQL Proxy, the complete tutorial. A very interesting session on hacking and adjusting it to fit your needs. It was held by Jan Kneschke (main author and developer) and Giuseppe Maxia (testing).
MySQL Cluster, with Stewart Smith. An amazing and thorough session on MySQL Cluster - all day long. There’s nothing better than learning from the guys that actually are writing the code, right? If you are curious, his blog can be found here.
In the afternoon, there were two very interesting sessions, but I had to pick only one of them. SQL Antipatterns (by Bill Karwin) was quite interesting, but I ended up at the Ask Bjørn Hansen’s session, called Real World Web: Performance & Scalability, MySQL Edition. This must have been one of the best sessions, ever (mostly because we’ve been giving the exact same advice to our clients for some time now).
This morning started with a keynote from Mårten Mickos (who used to be MySQL’s CEO, but his “job title” must have changed after the acquisition by Sun). His speech was followed by Jonathan Schwartz’s (CEO of Sun) and after that, we heard from Werner Vogels (CTO of Amazon.com). Quite interesting, but I’m not about to repeat everything they’ve said. Instead, I’m linking Colin Charles’s post, Ahead in the Cloud by Verner Vogels.
I’m running to another session now, so… keep tuned: more news will follow!
As you probably have already heard Innodb Announced new Plugin version for MySQL 5.1 So now you can see Heikki and the Team were not just doing only bug fixes for last two years, but rather kept very quite.
We had access to this code for few weeks and should say we were impressed in quality (we found only one crash bug which was fixed in less than 24 hours) as well as performance improvements to compression and fast index build functionality. As it is now publicly released we’ll try to put it to some production slaves to see how well it works.
There are still usability issues with this release (which you can blame both MySQL and Innodb for) - for example neither of standard data load tools (mysqldump import, using LOAD DATA INFILE or ALTER TABLE from other storage engine) would use Fast Innodb Index creation. Keep it in mind if you decide to benchmark/compare it.
If you would like to learn more about this Plugin you’re welcome to come to presentation by Heikki and Ken
which will be followed by my presentation on Innodb Scalability Limits. I will not go a lot into this plugin performance because I did not know when it would be released until very late and so if I can show any benchmark numbers for it at all. But still there are some and they are pretty cool.
P.S I’m also very happy to see Innodb continues to provide full Server functionality under GPL License.

打算熟悉下perl，自然主要用于数据库管理和监控方面的，所以需要连接数据库。Perl连接数据库可以通过DBI模块和相应数据库的DBD驱动，上一篇记录了DBI模块的安装，这里记录下DBD::mysql驱动的安装。可以从CPAN下载相应DBD驱动。
安装过程很简单，下载解压：
gzip -d DBD-mysql-4.006.tar.gz
tar xvf DBD-mysql-4.006.tar
然后进入DBD-mysql-4.006目录，执行：
perl Makefile.PL
make
make test
make install
检查已经安装好的Perl模块：
# ./perl-module.pl
DBD::mysql
DBI
Perl
安装DBD::mysql需要mysql_config，包含在Headers and libraries安装包中（MySQL-devel-community-5.1.23-0.rhel4.i386.rpm），并且PATH环境变量中必须包含mysql_config所在的路径。否则在执行perl Makefile.PL生成makefile的时候会报错：
Can’t exec “mysql_config”: No such file or directory at Makefile.PL line 76.
Cannot find the file ‘mysql_config’! Your execution PATH doesn’t seem
not contain the path to mysql_config. Resorting to guessed values!
Can’t exec “mysql_config”: No such file or directory at Makefile.PL line 466.
安装好DBI和DBD::mysql后，就可以访问MySQL数据库啦，首先在test库中创建一个table：
create table test(id int,name varchar(30))
然后执行下面的Perl脚本插入一条数据并且查询得到结果：
#!/usr/bin/perl
use DBI;
my $dbh = DBI->connect(”DBI:mysql:database=test;host=localhost”,”NinGoo”,”password”, {’RaiseError’ => 1});
my $rows = $dbh->do(”INSERT INTO test (id, name) VALUES (1, ‘NinGoo’)”);
my $query = $dbh->prepare(”SELECT name FROM test”);
$query->execute();
while(my $rs = $query->fetchrow_hashref()) {
print “$rs->{’name’}\n”;
}

The UKOUG call for papers has been announced. This is an event I've personally attended every year now since 2003. I've met and made some very good friends at this conference. I strongly recommend it as a technical forum. It is a large but not overwhelming large event - with lots of technical content (and a bit of fun as well).
I've written in the past about participating in the user community - this is the perfect chance. Everyone has something useful to contribute - everyone does.
So, get on the OTHER SIDE of the podium. Yes, it can be scary, but it is definitely worth the fear factor long term.

一个很有意思的技术嫁接。Pythian 发布了一个 MySQL 插件，通过该插件，Oracle 10g 的 Enterprise Manager Grid Control 能够用来管理 MySQL 。
在 Oracle 10g 刚发布那会儿，EM 的地位在整个链条中倒是挺重要的，几年下来，似乎并没有占领多少市场。我个人觉得这个工具挺"重"的，倒是很少看到有 DBA 用这个工具。
尽管这个 MySQL 插件应用场景可能不多，但这还是第一次看到第三方给 Oracle EM 带来扩展能力。
比较关注即将召开的 The 2008 MySQL Conference & Expo，Sun 收购 MySQL 之后第一次大规模亮相，能带来什么? 新版本的特性基本了解了，还有呢?
Updated: InnoDB Plugin 1.0 for MySQL 5.1 也需要关注一下。

战争的导火索缘自eBay新任首席执行官约翰•多纳霍（John Donahoe）推行的销售政策变革。这项于上个月开始生效的政策包括：将收费提高66%之多；对通过其支付伙伴PayPal的部分付款延迟21天交付；禁止卖家向买家给出差评。在DelphiForums, Allspark Forums 和eBay讨论版上议论纷纷的卖家表示，他们最担心的是最后一项改革。
最新的政策改革表明，卖家支付的费用水平将与其级别挂钩。卖家的级别越低，所需支付的费用就越多。交易量较低的卖家将更快受到差评的影响，因为其须支付的费用占总交易额的比例将会更高。除此之外，禁止共享恶劣买家信息的规定，也剥夺了卖家保护自己的一个工具。
1月29日，新政策刚刚公布，心怀不满的卖家玛丽•基莲（Mary Killion）就在eBay论坛上发布了一张号召罢工的帖子，标题为“签署联名信——2月18日至25日停业！”。该帖收到15331篇回复。之后，YouTube上的号召视频点击收看次数达到110369，并相继出现9段类似视频。接着，一份请愿书在网络上传播，Facebook和My Space上都出现相同主题的网页。2月18日，成千上万的eBay卖家开始集体停业一周。
浏览一下各论坛，你会发现恶劣买家似乎遍布eBay。其中，AllSpark.com的讨论版专门致力于揭露那些诈骗卖家的买家。琼森已在eBay上销售了7000件物品，她讲述了一个例子：有个买家使用5个不同的用户名, 购买商品后宣称没有收到货物，从而成功通过信用卡付款撤销获得大笔退款。Paypal的政策规定，卖家需核实买家已收到商品。如果卖家为省钱没有购买或忘记购买跟踪服务，而买家声称没有收到货物，买家将得到全额退款，无需任何调查取证。
琼森称，一些买家已经受到eBay新规则的启发，企图占便宜。“已经有买家用给出差评作要挟，要我搭送更多商品，他们没有意识到改革尚未完全生效……那些想要退款，或者仅仅是不喜欢商品颜色的买家现在有了豁免权。”
为什么要进行这一变革，人们对其原因议论纷纷。卖家们猜测，任凭卖家等级下滑，可能是一个更大策略的一部分。这些卖家以南茜•鲍尔曼（Nancy Baughman）为代表，她是网上卖家联盟（Online Seller Cyber Union）主席，曾出版《买吧、卖吧、赚钱吧》(Buy It, Sell It, Make Money)一书（由iUniverse.com出版）。
“有报道称，多纳霍希望eBay能摆脱跳蚤市场的感觉，”鲍尔曼称。“怎样做到这一点？从淘汰小卖家开始……”
然而，eBay发言人何塞•马拉博只表示：“网站改革旨在保持市场和用户体验的长期健康发展。关于抵制现象，我们还处于观望状态，因为现在考虑它还为时过早。”
像谢丽儿•琼森这样的卖家永远在寻找新的“港湾”。她已经将拍卖活动转移到iOffer.com网站，这是交易量仅次于eBay的第二大拍卖网站。而这样做的部分原因是Paypal的21天延期交付政策。她表示：“你不可能去商店拿回一样东西，然后21天后，在决定留下它时，才付钱给商店。”
琼森并不是孤身作战，她是名为“搬到iOffer的eBay卖家”的社团组织的一员。Power Sellers Unite是一家跟踪统计即时在线拍卖交易数量的网站，他们的数字统计显示，eBay的交易正在向iOffer、Bidville、eCrater、Bidtopia和HiBidder.com等同类网站转移。
鲍尔曼正在创建自己的评价论坛。“我们将承担本应由eBay承担的工作。我们开始制作网上卖家黑名单，努力公平对待买家，并防止出现诽谤现象。”eBay已经注意到她的举动。“7天前，他们将我踢出了eBay论坛。他们称之为仇恨言论。”
提姆•丘奇（Tim Church）是MySpace上罢工网页的创办者。他表示，下一轮抵制行动将于5月1号开始，并无限期持续下去。“作为卖家们坚持抗议的回报，我们已联系了另外4家网站，让他们做好准备，因为我们将对他们进行宣传推广，并吸引买家去这些网站购物。”
希尔•唐跟踪时尚，并经营着HipGuide有限公司。

今天看凤凰卫视采访，才知道有Anti-CNN这样一个网站。
Google一下，才知道这个网站已经颇具影响力。
Anti-CNN的目标是：
我们并不反对媒体本身，我们只反对媒体的不客观报道。
我们并不反对西方人民，但是我们反对偏见。We are not against the western media, but against the lies and fabricated stories in the media.
We are not against the western people, but against the prejudice from the western society.
支持真相，也支持世界在真相面前走向更加开放与自由！
奥运圣火在法国的遭遇也导致最近"抵制"这两个字日益火爆，关于家乐福的信息不断出现，电视上法国的声音也开始出现。
2008年注定会是不平静的一年！

这是刚才和网友在MSN上的聊天记录，应他的要求发到博客上，希望能对初学存储技术的朋友或正准备换工作的朋友有用。当然他的名字也按他的要求去掉了。
网友 说 (19:51):
你好呀 在吗？
sansky 说 (19:51):
我在
网友 说 (19:52):
我想再问问工作的事情 你有时间吗？
sansky 说 (19:52):
说吧
网友 说 (19:52):
你们售后的工作主要是做什么呢？
网友 说 (19:53):
安装 调试一类的？
sansky 说 (19:53):
对
网友 说 (19:53):
换电源 硬盘的机会多吗？
sansky 说 (19:54):
呵呵，经常会有
网友 说 (19:55):
你们的存储软件有哪些呢？
sansky 说 (19:56):
很多，
网友 说 (19:57):
我是觉得如果还走售后的话 就学一些更深入的技术 别每天换个电源 硬盘之类的 没技术含量 作久了一点好处都没有 不然就去做售前 积累些经验
网友 说 (19:59):
你们的售后是全国飞吗？
sansky 说 (20:00):
呵呵，售后能做的事情很多，比如测试，解决方案测试，应用系统测试，公司或个人的研究测试，我的存储技术全都是当年做售后时学来的，也见过很过国外的售后工程师，他们研究的都很深入。
sansky 说 (20:01):
一般来将都是分区域的，当然不排除支持其它地区。
网友 说 (20:01):
山东是属于哪个区呢？
sansky 说 (20:02):
北京
sansky 说 (20:03):
公司的支持点分为北京、上海和深圳，北京是总部
网友 说 (20:03):
我发现我们这帮售后每天都是忙着出差，赶时间去客户那
sansky 说 (20:04):
呵呵，售后就是灭火的，无论哪个公司都一样，没有故障就没有事情，
网友 说 (20:05):
而且觉大不部分都是换硬件 很少跟软件有关系
网友 说 (20:05):
我现在发现我系统方面的知识太少了
网友 说 (20:06):
每天就跟一帮电源 硬盘 打交道
网友 说 (20:06):
都提不到软件那个档次上去
sansky 说 (20:06):
呵呵，
sansky 说 (20:06):
换硬盘是初级工程师的事情，
网友 说 (20:07):
我们这似乎还没有一个高级的
sansky 说 (20:07):
UIT的售后工程师分4级，工作内容都是不一样的。
网友 说 (20:07):
最高级的是做什么呢？
sansky 说 (20:08):
呵呵，看我博客上的要求，
网友 说 (20:09):
软件一类的东西 我也在看 但平时都用不到 看了也就忘记了
网友 说 (20:09):
没有机会去做
sansky 说 (20:12):
用不到的时候就不要看软件的具体配置和命令之类的很细节的东西，记不住，也不用记，有用户手册呢。现在要学的是各种软件的原理，实现方式，和安装调试时要注意的关键点，明白为什么要这样设置就行，这些东西学会是不容易忘记的。
网友 说 (20:13):
恩 很有道理哦
网友 说 (20:13):
忽然发现 你们的售后已经招满了啊
sansky 说 (20:13):
是啊，
网友 说 (20:14):
看来我是没机会了
sansky 说 (20:15):
呵呵，你的简历还可以发到我们人事部，先备个案，以后有机会就会先找你的。
网友 说 (20:16):
我是觉得你为人很不错才投的 如果是去其他人手下干活 我还不一定去呢 呵呵
sansky 说 (20:17):
呵呵，
sansky 说 (20:18):
听到你说的，真的很高兴，
网友 说 (20:18):
你们售前没有起点稍微低点的岗位吗？
sansky 说 (20:19):
售前也分4个级别，你可以看看每个级别的要求，
网友 说 (20:20):
助理工程师：
熟悉公司各项产品的技术规格参数，功能特性
可完成针对具体存储产品采购需求的技术交流、需求分析，方案和投标书。
能准确完成产品配置清单。
这个不是很难 呵呵
sansky 说 (20:21):
呵呵，可工资也很低啊，3000左右，
网友 说 (20:21):
真是伤心
sansky 说 (20:22):
都是面向没什么工作经验，懂存储基础知识，具有一定演讲能力的人的，何况现在工作比较多，能不招就尽量不招的。
网友 说 (20:23):
突然发现我似乎没有竞争力
sansky 说 (20:25):
呵呵，能体会这一点是好事，我也是从这个阶段过来的，持续几年的低工资，持续几年的努力学习，慢慢熬出来的。
网友 说 (20:26):
你多大了？
sansky 说 (20:26):
存储是一门很容易入门，但做好却很不容易的学科，
sansky 说 (20:27):
34了，6年前接触存储，在存储公司里呆了两年半。
网友 说 (20:27):
我比你还小几岁
sansky 说 (20:28):
呵呵，这就是你的优势，你的起点比我高，以后的成就一定比我大，
sansky 说 (20:29):
存储是我毕业后10年间做的第5个行业，
sansky 说 (20:29):
换了好几次才换到存储的，
网友 说 (20:29):
看来你对这一行非常满意有
网友 说 (20:29):
呀
sansky 说 (20:30):
是这一行业目前的收入还不算太差，何况年龄越来越大了，不敢轻易再换另一个了。
sansky 说 (20:32):
无论那个行业对个人来将都是一项工作，能挣钱养活家人就行了，如果能从中获得乐趣就可好了。
网友 说 (20:32):
呵呵 听了那么多 我收获颇丰 感谢你的分享
网友 说 (20:32):
我觉得可以聊天记录放到你的网站上
网友 说 (20:32):
让其他的人也看看
网友 说 (20:33):
也可以增加网站流量
sansky 说 (20:33):
呵呵，可以啊，
网友 说 (20:33):
不过要把我的名气去掉 呵呵 我怕出名
网友 说 (20:34):
好了 改日聊 我要回去了
This is the second in our series co-publishing with Fedora Interviews.
In Fedora, the supported method for upgrading from one release to the next is by downloading the media and rebooting from the media and using Anaconda. Why was this the case, and what’s wrong with a yum upgrade?
Seth Vidal: Anaconda has the advantage of running outside of the system it is upgrading. This means it can do certain tricks in the event of big changes. The lvm->lvm2 migration, for example. Yum can’t do this. Changing the partition or fs type on a running partition is a bad idea :)
Will Woods: Another good example: In Fedora 9 we have (experimental) ext4 support, and Anaconda is capable of migrating your ext3 filesystems to ext4 automatically. But yum upgrades can’t handle this.
Even if it was possible–would you really want your F8 kernel (with old, broken, or non-existent ext4 drivers) messing around with your filesystems? No, you should probably be running the new F9 kernel to do that.
Seth Vidal: However, in a huge number of the cases, a yum upgrade worked fine for updating your distro. I’ve been updating my laptop for quite some time that way; lots of people have.
Will Woods: Live upgrades are kind of crazy. It’s a frequently-requested feature, especially from people coming from Ubuntu or Debian: “Why doesn’t Fedora have ‘apt-get dist-upgrade’! It’s so simple and easy!”
Well, it’s actually not that simple or easy. Have you actually read the 20 pages of directions for preparing for an upgrade? Or the 11-page-long list of potential problems with performing such an upgrade?
Yum upgrades use your (now old and out-of-date) yum, rpm libraries, kernel, etc. to perform the upgrade. And they do it on a running system! All sorts of weird things can happen when you upgrade the entire system while it’s running.
And now you’re developing pre-upgrade, which should land in Fedora 9. How does this work, and how does it resolve some of the problems faced in the traditional Anaconda update or yum upgrade?
Will Woods: A traditional Anaconda upgrade involves downloading and burning media. This is time-consuming and a bit wasteful–the media contains upgrades for packages you probably don’t have installed, but lacks upgrades for packages from the Everything repo or from third-party repos. So you’ll still need to download upgrades after the upgrade finishes!
If you upgrade over the network, you download a lot less data, but you have to sit and wait while anaconda fetches all those packages.
The PreUpgrade feature has two parts:
1) A GUI for F8 that downloads the F9 installer and *only* the packages your system needs to upgrade.
Seth Vidal: The boring part of an anaconda upgrade is when it resolves out what you need based on what’s installed and when it then downloads all the packages you need to do the upgrade. It’s boring, it is potentially error-prone when using flaky network connections, too.
So preupgrade uses the same depsolving logic from anaconda/yum, downloads all the metadata and packages you need while your normal system is running. So while you play tuxcart or other work the boring part of the anaconda upgrade is happening in another window.
Will Woods: This saves you time and bandwidth - and you don’t have to burn CDs/DVDs either.
2) Anaconda support for upgrading from a bunch of packages that are already on the target system.
Once everything is downloaded, you hit the “reboot” button and your system magically reboots into the Fedora 9 installer. It finds everything you’ve downloaded and installs using that.
How does this method compare with similar use cases in other distributions?
Seth Vidal: Fedora has live upgrades using yum upgrade Fedora has interactive installs using anaconda Fedora has scripted installs using kickstart Now Fedora has a way to preload your cache before doing an install - using preupgrade.
Will Woods: So you can upgrade with the convenience and bandwidth savings of a live upgrade, but without the risky craziness inherent therein.
By the time people read this, the feature will have landed in Rawhide. Is it possible for users to test the software by doing an update from Fedora 8 to Rawhide, and if so how?
Will Woods: Indeed it is! It’s pretty easy, too.
By now, the “preupgrade” package should be available in updates-testing for Fedora 8. Enable the updates-testing repo and install it. It currently shows up as “Upgrade Fedora” in your Applications -> System menu.
From there, it’s very simple - follow the screens to choose what to upgrade to, wait for everything to download, hit “Reboot”, and the upgrade will begin!
Once testing starts, is there a lot of work to be done on the technology before it’s ready for Fedora 9, or are you quite happy with its current status? Are there more features you’d like to see get added, either in the Fedora 9 time frame or beyond?
Seth Vidal: There are always more features. :)
Will Woods: There’s a couple of bugfixes and some UI improvements on the roadmap for 1.0 (which we plan to release in time for Fedora 9).
In the future we plan to better integrate preupgrade with the Fedora mirror system - the list of available releases will be on the mirrors, and when we do a new release you should be able to get a nice popup that says something like “Fedora 10 has been released [click here to upgrade]”.
Someday it should also let you pick your favorite mirror and get upgrades from 3rd party repos as well.
And, of course, we plan to do full i18n support so everyone worldwide can enjoy easier (and saner) upgrades.
And finally, would you like to tell us a little bit about yourselves? What got you interested in free software originally? What you like to do with your spare time when not working at the computer?!
Seth Vidal: I garden and ride my bike around.
Will Woods: I wrote my first program in BASIC, on our Atari 400, at age 3:
10 PRINT “DO YOU WANT TO GO SWIMMING DAD?”
20 GOTO 10
In high school, wanting a free C compiler, I ended up buying a copy of Slackware Linux Unleashed. I’ve been hooked ever since.
When I manage to get away from the computer, my wife and I make comics, play video games, and bother our cat.
Reading evening news and rss feeds I found interesting next sequence:
Jeremy’s post “MySQL to launch new features only in MySQL Enterprise“
basically about some new features of MySQL will be available only for paid customers
Then Kaj’s post Anthropology: Sun studies MySQL with tagline “Sun didn’t acquire MySQL to change it, but to learn from it”
And finally news Sun Tackles Video Codec with info “Sun is working on a royalty-free and open video codec and media system”
What is interesting for me - while Sun moves to make most products OpenSourced - to name OpenSolaris, OpenJava, OpenOffice, and develops new open sourced software (see above about videocodec), MySQL tries to hide something.
Year ago I remember MySQL Proxy was not available for wide usage, only for Enterprise customers. Fortunately it was changed during last year. Now we see that new features will be available only for Enterprise customers. What is that ? Does not MySQL believe in open source? Or just partially believe ?
Why does Sun decide to develop new software under OpenSource license, but MySQL decides to take away features developed for next version.
Well I understand this all is about money, and anyone is free to do with his product anything, but MySQL does not seem playing open game here.
