I’v switched MoinMoin version from 1.8 to 1.9, and the running method from standalone to fastcgi.

As of 1.9.3 released a few days ago, MoinMoin has a bunch of changes. For those who wanna upgrade from 1.8 to 1.9, here’s some advise:

• Read the changelog, linked above. Pay attention the “HINT”s.
• Get to know the requirements by MoinMoin.
• Read the doc on updating MoinMoin.
• Do exactly as the docs say, especially, watch out for your data, BACKUP can save your life.
• Follow the above four points.

I’m running MoinMoin 1.9.3 currently. Taken as a whole, it looks like below:

Client ----> Nginx Web Frontend -----------+
                                           | fastcgi_pass
                                          \|/
                            +-------------------------+
              moin.fcgi     | spawn-fcgi-moin.socket  |
spawn-fcgi ---------------> |           or            |
                            |     localhost:port      |
                            +-------------------------+

      }

The fix_script_name is very useful. With this setting, neither

proxy_set_header  X-Moin-Location /wiki/;

nor

fastcgi_param SCRIPT_NAME /wiki;

is no longer needed in Nginx If you're running MoinMoin at http://domain/wiki/.

Anyway, this scenario is a just work usage. As MoinMoin is now a WSGI server, and using flup as the middleware for communication.
All these stuff is making things more complex.
BTW, flup author said that he didn't use flup himself anymore 2+ years ago. I've no idea how is it now.

The simplest way is just to use "standalone" wikiserver.py bundled with MoinMoin, if you don't care about scalability and etc.. That also makes your life darker, LOL.

小盆友，请原谅，我未经你的同意拍下你，还放在这里。
上图拍摄时间是晚上11点20分，地点是公交车上。不知道在这个周末的夜晚，对他意味着什么，以至于在这么不安静的车厢里，他能靠着书包，睡得如此优雅平静。但愿是吃饱喝足玩的尽兴了。

哥走了，哥大概累坏了吧。站在这里的时候，心里很不是滋味。不由得想到中国深圳富士康的N连跳，倒是一小撮不明真相的国外公司积极展开调查评估。

前几天的一个夜里睡不着，打开电视看了会儿CCTV-2，讲的是记者调查暗访几个楼盘的入住率，根据人员流动率和晚上亮灯率，得出的结论是调查对象里40%左右的房屋空置。节目最后挖了个坑说这些买了房而不入住的人，到底是什么原因。好样的，直接把舆论导向塞给观众，把矛盾对立面架在炒房的和想买房而买不起的人之间。
为什么在2003年把80%的经适房改成事实上的商品房，为什么不大力调整住房结构，为什么不加大尺度地更多地向民间游资开放投资渠道和环境。
偶尔看看央视，是锻炼智商的充分不必要条件。

一系列政治社会体制注定了中国的特立独行，一系列教育体制导致了大多数中国人麻木的奴性。曾经在某人的blog上评论说了中华民族的劣根性，被鄙视了，是我醒了还是他仍醉？
中国就是个山寨。大到社会，小到公司，单位，乃至个人。

我很想问问那些战斗在审查线上的东西们，核技术被应用到战争里的后果是什么样的；你们重蹈覆辙就不累么；你们这些历史的罪人，出卖了灵魂苟且偷生，连鸡都知道，啄米的时候别忘了不停地抬头。

今天才知道某个牛逼同事的遭遇，再次让我对微软的人失望。还有一个牛逼的同事也离开了公司，也受够了来自微软的两位高人的折腾。哥几个都累了。今天某内线说Yahoo!北京研发院里有很多微软的，心里一凉一热，很庆幸上次对那个offer没太感冒。
关于公司，有很多关于技术和制度方面的苦水，也许类似老外发现腾讯QQ里的dirty codes一样。太消极了，早已没有吐出来的积极意义。而且也看得出来，国内的这些公司，大都一个样。

前两天问一个同事，如果给你很多钱，你会不会去做GFW。答曰，有钱谁不去啊。太诚实了，也很悲哀。

在这个物权横流，金钱至上，信仰缺失的山寨里，有多少人能够坚持作为社会人的责任感，有多少人积极地去推动历史的车轮逆势而上，而不是等着它坡起熄火来不及刹车被一辗而过。

改革创新，不应该被挂在嘴上。它是流动的血液，看不见摸不着，却是保持生命的根本，它永远不会累。

但愿有一天，我能见证中国的崛起，而不是眼前的外强中干。但愿有一天，尼姑思凡。

<cli> hi there, i wanna deploy Slackware with reiserfs file system, is it possible?
<chesty> are you trolling?
<cli> Slackware use reiserfs by default, why linode use ext3 in the system image?
<cli> chesty: no
<chesty> ah right, i didn’t know that. maybe the control panel doesn’t support reiser natively like it does ext3?
<chesty> not sure
<cli> it’s a pity
<chesty> i thought reiser was dead?
<internat> reiser will kill you;)
<cli> chesty: not yet
<cli> internat: lol
<mikegrb> lolz
<chesty> oh right, that’s Mrs reiser that’s dead

本着尝试寻找问题，而非制造问题的原则，拆鸡鸡到此结束。

没有SIM卡，我很沮丧：

紧了紧线，亲了亲GPS芯片，恢复鸡鸡。然后，能试的都试了，还是不能搜到星，我彻底死鸟心。
下一站，有时间再去折腾。

那时候做出离开的决定之前，没少挣扎。两年差不多正好到一个平台期，尤其对于刚入社会的人来说。蔡琴说，人生的际遇，稍纵即逝。最后一现实，一狠心，先撤离。一直很感激大家的理解和支持。

对杭州这个城市的感觉，就是没有感觉。
正如大海当初所说，工作上也就是颗螺丝钉。不过，所接触的，所掌握的，所理解的，都是很难得的价值。这些都让我能把工作做得更好。当然，不是所有事都完美无可挑剔，也许我太偏执。
平时的生活，跟在北京时不能比。也许是我自己的问题，但是我怎么就没再遇到像Sliver等这帮损友呢。也许<<The Shawshank Redemption>>里Andy与Red的感情，只是用来推崇的。

这一年，迷茫中努力，寂寞中持续。对下面这两句台词有很深的体会：

First you hate them, then you get used to them. Enough time passed, get so you depend on them. That’s institutionalizing.

Remember, hope is a good thing, maybe the best of things and no good thing ever dies!
Get busy living or get busy dying.

Hope is good, action is better.

常被指思维太跳跃，想象过丰富。多次控制所写内容不偏题，虽然想说的太多，就说这么点好了。

echo "while the one WITH is at \"${log}.$(echo ${dropcache}|cut -d' ' -f2)\"."
echo "Check the diff log between the two at \"${finallog}\"."

I’m afraid the dropcache test doesn’t make much sense, added here for just in case somebody think it should be token in consideration.
The suffix of tmp-file(dded) names indicates the file size, in bytes. No more explanations, please read and run and think for yourselves, if you wish.

For my situation, I’m using compression level 4 within Nginx, on a Pentium 4 2.8GHz, 512 KB cache size CPU.

function gg() {
  if [ $# -gt 0 ]; then
    for i in $(echo $*); do
      if [ -d ${i} ]; then
        ( cd ${i} && git pull )
      else
        echo "No such directory: \"${i}\", skipping ..."
      fi
    done
  else
    echo "usage: gg <git repo dir>"
  fi
}

The parameters can be either relative directories or absolute directories, wildcard is supported.
If there’s any better ways, such as Git’s internal methods, please let me know. Thanks.

Several days during the end of last month, the server was took offline and got a hardware reconditioning. Meanwhile, the OS refreshed, lots of garbage cleaned.

Before that, only 1GB RAM was available, the system was running Slackware Linux 11.0 with customized 2.4.x kernel. For some historical reasons, bloated Apache was chosen as web server.

Those are all turned into the bad old times. I’m pleased for the reforms as below:

1. The server got 3GB RAM. TBH, it’s so piteous little. Even my laptop has 4GB RAM, and planning to upgrade it to 8GB.

2. Slackware Linux Current is running. Yeah, it’s so called bleeding edge. But with whichever version, Slackware Linux is damn stable for me. Making it more bleeding edge is my pleasure. Anyway, risks is always there, but you’ve got your head there too. So, some kernel features are now available, like epoll, which was lack in 2.4.x kernels. I used to try the epoll patch for 2.4 kernel, but with no luck, and the system got unstable.

3. Goodbye Apache, hello Nginx. I finally get an running Nginx web server! This proposal comes true.

4. Mod_php within Apache was replaced with PHP-FPM, which is no longer a patch but now standalone, announced just yesterday, mentioned by Paul Gao in Google Reader shared items.

With these changes, from now on, I can smoothly keep up with the newest apps (versions). Strict system management rules will be carried out.
