Symbian S60 Opera Mini 复活指南

2009-11-25T09:36:00.000-08:00

最近有不少介绍复活 Opera Mini 的文章， OPM Server Mirror 项目也给出了 JAR 包，但不幸的是我没能在其中找到适合我的 Nokia E61 用的版本。JAR 包安装时总是出现 "Authorization error" 或 "Certification error" 等警告并失败，我把能用上的解权限的的招都用上也都不行。我懒得再去签名啥的，幸运的是终于 Google 到了一个能用的 Opera Mini Mod (直接下载 Opera Mini 4.2 Mod)。

上面的那个 4.2 mod JAR 包在我的 E61 上安装顺利。装好运行后需要配置一下 Opera Mini Server:

在 Tools -> Settings -> Handler Menu 中设 HTTP Server，具体值见这里，当然自己用 OPM Server Mirror 给的脚本搭个 proxy 更好
Socket Server 也建议改一下，不然还是会见到 Opera 主动和谐的那个页面，设成 socket://127.0.0.1:1080 即可

到这里 Opera Mini 已经复活了。不过在每次进 Opera Mini 时可能还是需要重新 test connection .

附加题：有兴趣的小朋友可能会想打 Socket Server 的主意。其实很简单，在你墙外的服务器上跑个 iprelay 即可:


iprelay -d 10080:64.255.180.253:1080

令人发指.com 的宕机

2009-10-14T09:10:00.001-07:00

这个 Blog 最近经常宕机，请不必太担忧。不是被墙了，我也还没有机会去喝茶。只是我爹妈家的猫很喜欢我放那儿的路由器，经常在上面爬来爬去；俺娘又怕电着了猫（解释电压之类是没用的），经常把电源断了。我整天天涯海角的乱跑，也实在鞭长莫及。几个月不 update 的 blog 还老宕机，实在不好意思，撰文以纪念。

昨个看了黄舒骏

2009-05-10T08:53:00.000-07:00

不想用什么煽情的标题，诸如“祭奠我们的青春”啥的。客观的描述就是我昨天带老婆去看了黄舒骏在上海的演唱会。

我们到的比较早，进去大概估了一下，也就 2000 个座吧。座位不好就不多说了，反正教训是如果还想看啥演唱会的话，买票一定要趁早。我买的是 380 的票，准确地说在 380 里也是靠后的。坐我那片的，还有后面 180 的，都是我们这样年纪大些的大叔和御姐（要照顾我老婆的情绪）们。一帮拿着专业的道具的小粉丝有组织地冲到了最前面。后来才知道，那些是在某个 BBS 某个讨论版里看某个选秀节目的。为此老婆还嘲笑了我，因为在很多年前，互联网泡沫破灭之前，我也是混那个 BBS 的。

原定 19:30 开始的演唱会拖了十几分钟才开始。黄舒骏上来就把我们定性为“坐在后面的”“年纪比较大的”朋友，还说他非常为那些年纪比他还大却自称听他的歌长大的人担心。我跟老婆说，我们周围的这些人不光是大叔，估计还多是宅大叔。的的确确，我们这些宅大叔们就是来听在我们（更）年轻时打动我们的那些歌曲。今天还看见有进步后生写 Blog ，说去看演唱会的宅大叔就是有钱，个个都攥着大炮筒，让他一个器材控很是眼红。

每个宅大叔都有自己心中盼望着的那几首歌吧，我左后方的一个宅大叔就一直念叨《那一年那一夜》。其实我也很想听到这首歌，不过的确不指望黄舒骏会在这场演唱会上唱别人的歌。毫无疑问，《改变1995》一定是很多人期待的，现场也在这首歌中到了第一次高潮。歌词改了，老实说，大叔们期待更犀利些的。好吧，告诉你们一个小秘密，我一直期望在我的葬礼上放这首歌。

江苏卫视的那两个姑娘实在让人不敢恭维。要说带徒弟，还是应该看看陈升带来的。不过没办法，这么场不赚钱的演唱会，要不是那几个黄舒骏混评委的电视台帮忙，还真办不成。大叔们很有礼貌，没把小姑娘轰下去。前面有组织的萝莉也挺招人烦，荧光棒、LED 板、横幅一样不拉，可总得考虑一下这些玩意和“你走以后没几天，邓丽君也跟我们说再见”很不搭吧。

黄舒骏自爆《两岸》中的人物乃是虚构，颇让我吃惊：这都是有名有姓的呢。唱完这首，他就谢幕退场了。

要说大叔御姐们就是太 nice ，居然有人就往外走了。（有个小插曲，我前面的御姐，估计是有事提前走了，走之前还小心地把座位后面贴的号取下带走了。）我那个急啊，就带头喊起了 Encore 。大叔御姐们就是 nice ，虽然一直在鼓掌，但喊 Encore 的还是不多。过了几分钟，估计黄舒骏对大叔们的耐心也没有太大把握，就上来了，说：其实我也有准备，如果没人喊 encore ，大家就这么安静的走了。还说：其实，我真的没有准备 ...... 太多的 encore 曲。

Encore 第一首是献给他的父母的。第二首，是大家盼望的《恋爱症候群》。黄舒骏说唱这首歌不能分心，戴上墨镜，说：“你们开心你们的，我唱我的。” 800 多字，一气唱下来，没错！副歌是大家一起和着的。唱到结尾，黄舒骏摘下墨镜；大家起立鼓掌，看他走到后场，继续 encore ！

大叔们还是不习惯喊 encore ，最后还是喊黄舒骏的名字比较有气势。喊了几分钟，黄舒骏跑上来说，这次是真的没有准备了。后来还是唱了《听不懂的话》。我们这些 nice 的大叔看准备没准备的 encore 都上了，也终于可以满意地回家了。

PS: 为了诸位大叔们心中的小小幻想，俺就不透露那个 BBS 那个版了。

Online Backup, Data Backup, & Online Storage Service for Windows, Mac, and Linux from Spideroak.com

2009-03-09T20:07:00.000-07:00

Online Backup, Data Backup, & Online Storage Service for Windows, Mac, and Linux from Spideroak.com: "SpiderOak provides an easy, secure and consolidated free online backup, storage, access, sharing & sync* tool for Windows, Mac OS X, and Linux (Ubuntu & Debian)"

I'm using SpiderOak for backing up my CVS root now. It's the simplest way I can find for online Linux desktop backup. Ubuntu Hardy AMD64 is well supported. But it requires a property client, which make it hard to use with server or low-end devices.

I registered drivehq.com also, which supports FTP. But I'm still looking for tools or scripts which can keep versions of backups with FTP: I don't want to program it by myself.

Update(3/11/09): the latest news, SpiderOak hung up hours after it was installed. Now, there are lot of files with status 0.00% and queued, but no change anymore. So, shall I switch back to backupninja, and programing a script for FTP?

Google Notebook: Still Available For New Users?

2009-03-09T18:08:00.000-07:00

Official Google Notebook Blog: Stopping development on Google Notebook: "Starting next week, we plan to stop active development on Google Notebook. This means we'll no longer be adding features or offer Notebook for new users."

I signed up a new Google account with a domain of my own (secutum.com), and accessed Google notebook successfully. It's a good news. I do take a lot of notes.

Zoho Creator AppEngine Extension

2009-02-24T04:44:00.000-08:00

Zoho Creator is a powerful Web application development tool. It can export project to Google AppEngine also. But you will be disappointed if you want to do any real task with the exported code, because there are some IMPORTANT LIMITS besides the ones mentioned officially:

* Some important actions against records are removed, including DELETE, UPDATE and SEARCH
* Data access is executed in a very expensive way, and has a limitation of 1000 record for each table
* No support for 1:N mapping between tables

There are some minor issues also:

* Values of input fields are not escaped

But as a developer without good skill of UI, I still prefer to create prototypes with Zoho Creator for RAD. It's not difficult to hack the exported code with Python, HTML and Javascript. But, the interacted development with Zoho Creator and local development tools is still a big challenge. So I started to develop a toolkit with can be used with this type of project:

* One-way update from Zoho Creator to local project
* Minimized changes to code generated by Zoho Creator
* Implementations of the missed features and fixes of known bugs of generated code
* A framework for further development

Following are some tools and skills I will use:

* jQuery powered JS library for Web page hack(minimizing the changes to generated source code)
* Regexp based code converting tools to apply changes to the generated code
* Diff for one-way update

Of cause, Zoho won't like my hacks, they want to keep user playing with their hosting service rather than exporting projects to Google AppEngine. But, we all know there will be some RAD tools for AppEngine soon or later. So, why don't Zoho take the chances of becoming a leader of this trend?

Update: Now, I don't think the AppEngine code generated with Zoho Creator is a serious implementation. I prefer to hang it up before it can handle a real task.

家用文件服务器

2009-02-22T00:43:00.000-08:00

这两天开始考虑攒个文件服务器了。总的来说作了以下几个方面权衡：

* 备选功能
** 文件服务
** 网络应用服务
** VM Host
** 视频播放，不要求支持 HD
** DVD Burning
* 系统架构
** Atom
** Athlon BE，据说(http://www.pcpop.com/doc/0/373/373434_4.shtml) AMD 功耗更低
* FS, RAID 策略, 有同学(http://www.tummy.com/journals/entries/jafo_20080705_130814)报告说 FUSE ZFS 能用，还说 RAID-Z 好
* 功耗和噪音，貌似(http://bbs.pcpop.com/070101/781254-1.html)硬盘(3到5块)将是大头
* 机箱，要够大
* 电源，为了硬盘，需要提供至少 200W 的电源
* HDD, 初期至少 SATA x 2 + IDE x 1 (我那闲置了大半年的 600G), 还得要个硬盘架
* DVD-RW，要光雕的

看来钱都是花在存储上了。机箱电源还要好好学习一下，据说单相电源省电，但那彪悍的硬盘组恐怕是要三相伺候的。

3000 RMB 的 File Server ，算是够有诚意了吧。要是放办公室，我就弄个 4U 的机箱，管他多大声呢。

Shrinking and Compressing Linux Virtual Image with Linux Host

2009-01-19T07:50:00.000-08:00

I was always short of disk, because I have several virtual machines with my laptop. The virtual disk sizes grows fast, even the actual disk sizes I saw in the guest machine are much smaller. So, it's really necessary to shrink the disks from time to time. And, I also need a good compressor which can provide better compressing rate.

Since I run Linux guests in Linux host, it's a little tricky to shrink the disks. After googling and trying several approaches, I got following solutions:

Shrinking with X Based vmware-toolbox

vmware-toolbox is easy to use, but it requires X. Of cause, for most of my vms, I don't want a X server in them. So, remote X server helps now. With xauth (Debian package xbase-clients, or Yum package xorg-x11-auth), X forwarding works with SSH:


ssh -X user@vm

Then vmware-toolbox can be called, and the window will be forwarded to your desktop.

Notice: vmware-toolbox doesn't support logical volume. Please see the following section for shrinking virtual disk with logical volume.

Shrinking with Command Line

If there's no X forwarding for the guest machine, the virtual image can be shrinked with command line also. The brief steps are:

* Download VMWare Server 2 package and unpack vmware-vdiskmanager from it. I'm still using VMWare Server 1 now, since the browser based client doesn't work well with my Linux. But the vmware-vdiskmanager doesn't provide the feature of disk shrinking.
* Create symbol links for libcrypto.so.0.9.8 and libssl.so.0.9.8 . Assuming the vmware-vdiskmanager is placed in folder /usr/local/bin, then the symbol links are:


sudo mkdir -p /usr/local/bin/libdir/lib/libcrypto.so.0.9.8/
sudo ln -s /usr/lib/libcrypto.so.0.9.8 /usr/local/bin/libdir/lib/libcrypto.so.0.9.8/libcrypto.so.0.9.8
sudo mkdir -p /usr/local/bin/libdir/lib/libssl.so.0.9.8/
sudo ln -s /usr/lib/libssl.so.0.9.8 /usr/local/bin/libdir/lib/libssl.so.0.9.8/libssl.so.0.9.8

Now, the new vmware-vdiskmanager with disk shrinking (-p and -k) works.

Then, shrink the disk:
(Following content are based on http://communities.vmware.com/message/257602 .)
* Power on the guest machine, fill the file system with zero:


dd if=/dev/zero of=zerofile bs=1024k count=2048
rm zerofile

And swap partition also (assuming /dev/sda5 is the swap partition):


sudo swapoff
sudo if=/dev/zero of=/dev/sda5 bs=1024k count=2048

* Shutdown the virtual machine.
* Mount the virtual drive using the vmware-mount command; e.g.


sudo vmware-mount.pl debian40server.vmdk 1 -t ext3 /tmp/debian40/

* Using the vmware-vdiskmanager prepare disk for shrinking; e.g. using v: as mounted drive:


sudo /usr/local/bin/vmware-vdiskmanager -p /tmp/debian40/

* Unmount the drive.
* Shrink the disk (it's recommended to execute the following command with common user, instead of root):


/usr/local/bin/vmware-vdiskmanager -k debian40server.vmdk

Now, the disk is shrinked.

If there file system is in a logical volume of the virtual disk, manual operations of LVM are required for the shrinking (based on information available at http://seattlecentral.edu/cgi-bin/cgiwrap/dmartin/moin.cgi/VMware#head-b6e75c6b7ea67c9dd57b2adb91c9367ccaa24bcd and http://www.debuntu.org/how-to-install-ubuntu-over-lvm-filesystem):

# Make sure the VG in your VM is not the same as any VGs you have anywhere on your host box.
# Stop the VM
# load the nbd (Network Block Device) module into the running kernel
# Make sure you have /dev/nb* (use "MAKEDEV nb" if you don't)
# run "vmware-loop -p filename.vmdk" and note which partition you have your LVM on
# run "vmware-loop filename.vmdk partition-number /dev/nb*" to attach the file to the network block device
# run "lvmdiskscan" to make it re-scan the disks
# run lvscan to see the nice list
# run 'lvchange -ay volgroup' where volgroup is the volume group on your VM (Please try sudo modprobe dm-mod on "Incompatible libdevmapper" error.)
# run lvscan to see the nice list, this time with your VM's LVs listed as ACTIVE
# Mount and play with LVs
# Then jump to the step of vmware-vdiskmanager -p

Shrinking with Command Line

Then, comes to the second goal: a compressor with better compressing rate. I archived a virtual machine folder with GZIP, BZIP2 and 7Z. Following are the archive files I got:


-rwxrwx---  1 root plugdev 195722873 2009-01-19 20:28 debian40server.7z
-rwxrwx---  1 root plugdev 262460006 2009-01-19 20:29 debian40server.tar.gz
-rwxrwx---  1 root plugdev 229599667 2009-01-19 20:34 debian40server.tar.bz2

Of cause, 7Z provides better compressing rate (and requires much longer compressing time). But, for me, it's worthy when comparing to the disk usage of versions of VM backups and transferring time cost over the network.

Web API for Getting Latitude & Longitude with Address or GSM Cell ID

2009-01-17T11:36:00.000-08:00

I developed a small web application, which provide a Web API for geting latitude and longitude with address or GSM cell ID.

To use it, just access it with the address or GSM cell ID/lac as parameters in URL:


http://marklet.appspot.com/geolocator/cellid?cellid=30559&lac=4471
http://marklet.appspot.com/geolocator/address?addr=北京王府井&of=xml

UTF-8 is supported for parameter addr.

Accepted of(output format) values:

text
xml

This Web API is implemented based on Google Maps service.

Ubuntu IEs4Linux Installation

2009-01-07T23:28:00.000-08:00

IEs4Linux is good. I used to access OWA(outlook web access) with Firefox, but OWA provides a very poor UI for browsers other than IE. I tried to provide a faked Agent field, but the page is incompatible with Firefox.

So, I tried IEs4Linux, and got IE 6 works with Ubuntu and OWA now. But I did found some issues during the installation.

* Corrupted DCOM98.EXE. Solution:


./ies4linux --no-gui

* swflash.cab: no valid cabinets found. Solution: download http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0 manually, place the file in ~/.ies4linux/downloads, and install it again.

Update: Beautifying Chinese fonts for Wine.

地图偏移真和谐

2009-01-07T01:38:00.000-08:00

自己随便拿 GSM Cell ID 做了个 Google Map 跟踪玩，赫然发现地图都便得厉害，差不多800米吧。查了一下，据说是：“这是国际惯例。大多数政府都规定航拍图必须人工加入位置偏移，不能给真实的GPS信息。这都有算法。”当然，看看后面，不明真相的群众们不会这么接受有XX特色的国际惯例的。

虽然有人说：“Google 地图手机版图层误差消失。“我试了一下，一般的搜索是没有偏了，可当我查询经纬度(如 39.974496,116.301469)时，还是有的。

很好，很和谐。广大不明真相的群众都在踊跃修正地图。

Multiple Keys Wireless Mouse for X Windows

2009-01-03T00:55:00.000-08:00

I bought a Rapoo 7100 wireless mouse weeks ago. It works with Ubuntu without changes of settings. But the multiple keys at left side act as right key and middle key. I tried ZAxisMapping of xorg.conf and xmodmap but it doesn't help. So, I found evdev.

Following are some configuration files I used:

/etc/hal/fdi/policy/10-x11-input.fdi for enabling hal for evdev:


<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
  <device>
    <!-- FIXME: Support tablets too. -->
    <match key="info.capabilities" contains="input.mouse">
      <merge key="input.x11_driver" type="string">mouse</merge>
      <match key="/org/freedesktop/Hal/devices/computer:system.kernel.name"
             string="Linux">
        <merge key="input.x11_driver" type="string">evdev</merge>
      </match>
    </match>

    <match key="info.capabilities" contains="input.keys">
      <!-- If we're using Linux, we use evdev by default (falling back to
           keyboard otherwise). -->
      <merge key="input.x11_driver" type="string">keyboard</merge>
      <match key="/org/freedesktop/Hal/devices/computer:system.kernel.name"
             string="Linux">
        <merge key="input.x11_driver" type="string">evdev</merge>
      </match>
    </match>
  </device>
</deviceinfo>

Disable other input devices for xorg in xorg.conf:

Dynamical Loading Remote Javascript With Greasemonkey

2008-12-28T18:47:00.000-08:00

Kaixin Toolkit for Greasemonkey is a Greasemonkey user script developed by me. Take a look at the script, you will find it does nothing but loading a remote script.

Yes. All the real tasks are implemented with the remote script. It means that the feature can be upgraded without reinstall the user script. The dynamic loading feature is provided by GMJSLoader. Actually, it did a little more than that. It exports Greasemnkey API the remote script also.

Yes. There are some security issue with this feature. Actually, I think the securer way for this feature is to provide a native interface of loading remote script in Greasemonkey.

陈升 - 牡丹亭外歌词:

为救李郎离家园
谁料皇榜中状元
中状元着红袍
帽插宫花好啊好新鲜
李郎一梦已过往
风流人儿如今在何方
从古到今呀说来话
不过是情而已
这人间苦什么
怕不能遇见你
这世界有点假
可我莫名爱上她
黄粱一梦20年啊
依旧是不懂爱也不懂情
写歌的人假正经啊
听歌的人最无情
牡丹亭外雨紛紛
谁是归人说不准
是归人啊你说分明
你把我心放哪儿
黄粱一梦20年啊
依旧是不懂爱也不懂情
写歌的人假正经啊
听歌的人最无情
可我最爱是天然
风流人儿如今在何方
不管是谁啊躲不过
还是情而已
你问我怕什么
怕不能遇见你
是否你走过了我身边
恍恍惚惚一瞬間
黄粱一梦20年啊
依旧是不懂爱也不懂情
写歌的人断了魂啊
听歌的人最无情
为救李郎离家园
谁料皇榜中状元
中状元着红袍
帽插宫花好啊……
好新鲜
为救李郎离家园
谁料皇榜中状元
中状元着红袍
帽插宫花好啊好新鲜
李郎一梦已过往
风流人儿如今在何方
从古到今呀说来话
不过是情而已
这人间苦什么
怕不能遇见你
这世界有点假
可我莫名爱上她
黄粱一梦20年啊
依旧是不懂爱也不懂情

南京电信的 DNS 劫持是在路由做的

2008-11-17T16:51:00.000-08:00

本以为电信是在 DNS Server 动的手脚。可测了一下才发现，南京电信的 DNS Hijack 是在路由做的，53 的 DNS Response 包如果是 NXDOMAIN 就会被换掉。真正的令人发指啊:


# nslookup non-exist.lrfz.com 211.93.80.129
Server:     dns.lnsy.cnuninet.net
Address:    211.93.80.129

Name:       A.test.test
Addresses:  202.102.113.182, 202.102.113.179, 202.102.113.180, 202.102.113.181

# nslookup jaisdjfaf.lrfz.com 202.112.20.131
Server:     dns.whnet.edu.cn
Address:    202.112.20.131

Name:       A.test.test
Addresses:  202.102.113.180, 202.102.113.181, 202.102.113.182, 202.102.113.179

也就是说，换 DNS 服务器都不行了，躲都躲不起啊。所以现在技术上可行的 walk around 办法只有用 dnsmasq 了，不过会用这玩意的用户恐怕连万分之一都没有。

又查了一下上海的(公司光纤接入，ADSL接入还待验证)，发现居然还有点不一样——这是在 DNS 服务器劫持的：


# nslookup non-exist.keotag.com 202.27.184.3

OpenWRT NAS Watchdog

2008-11-14T19:33:00.000-08:00

I set up a WDS network with two OpenWRT powered Wifi routers in my apartment. It was found soon that the client router, which has less memory and less services, breaks several time every day. Today, I found that the nas process crashed. Without check the patches I found at OpenWRT dev web (https://dev.openwrt.org/ticket/164, https://dev.openwrt.org/browser/trunk/package/madwifi/patches/111-wds_fix_PR_914.patch?rev=5903), which are quite old (I'm using the last version WhiteRussian), I just implemented a cron job watchdog with shell:


#!/bin/sh

# /usr/local/bin/nas_watchdog

pid="$(cat /var/run/nas.lan.pid 2>&-)"
[ -n "$pid" -a -d "/proc/$pid" ] && exit 0

echo "Restarting WPA ..."
/etc/init.d/S41wpa
exit 1

And my crontab:

11月14日，我打南京 10000 投诉了 DNS 劫持问题。一位男性工作人员很耐心地询问了具体情况(我当时提供的例子为 www.keotag.com)，并表示将向上级反应情况。随后他打电话给我并建议我使用 61.147.37.1 做 DNS 服务器，但并未解释在 218.2.135.1 进行的 DNS 劫持行为。

11月15日，我再次拨打南京 10000 投诉了 HTTP 劫持问题。一位女性工作人员接了电话，未询问具体情况，仅表示将安排相关人员与我联系。

HTML XPath/XSLT Access Example

2008-11-06T09:44:00.000-08:00

In the comments to a previous post of mine, Uche Ogbuji mentioned that there's an implementation of robust XPath and XSLT solution for HTML with html5lib + amara2. I tried the sample he provided. With a quick bug fix, it works.

Amara is based on 4suite, which is not supported by Google App Engine now. So, I turned to look for a pure Python solution, and found lxml + html5lib. Following is a simple example:


import lxml.etree
import html5lib
import urllib

p = html5lib.HTMLParser(tree=html5lib.treebuilders.getTreeBuilder("etree",
                                                                 lxml.etree, fullTree=True))
f=urllib.urlopen('http://www.tudou.com/playlist/id/4527368/')
t=p.parse(f)
f.close()

container=t.xpath("//div[@class='programs fix']/ancestor::*[1]")[0]
lxml.etree.tostring(container)
programs=t.xpath("//div[@class='programs fix']")[0]

fxsl=open('tudou.xsl')
xslt_doc = lxml.etree.parse(fxsl)
fxsl.close()
transform = lxml.etree.XSLT(xslt_doc)
lxml.etree.tostring(transform(programs))

HTML file used in above example.

XSL file used in above example:


<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match='div'>
    <html>
      <body>
        <h1><xsl:value-of select="h2" /></h1>
        <ul>
          <xsl:for-each select='div/div[@class="pack pack_clip"]'>
            <li>
              <xsl:value-of select="ul/li[1]/a/@title" />
            </li>   
          </xsl:for-each> 
        </ul>
      </body>
    </html>
  </xsl:template>
</xsl:stylesheet>

RFC 1123 Datetime Parsing with Google App Engine

2008-11-05T07:47:00.000-08:00

Since datetime.datetime.strptime() support RFC 1123 datetime format, which is used in MIME headers for mail protocols and HTTP, with limited timezones (i.e. UTC, GMT, and local timezone of the host). With the following code, ValueError will be raised on time strings of any other timezones.


def _pdatetime(s):
    return datetime.strptime(s, '%a, %d %b %Y %H:%M:%S %Z')

With the help of module email and time, this issue was walked around:


import datetime, email, time

def _pdatetime(s):
    return datetime.strptime(
        time.strftime('%a, %d %b %Y %H:%M:%S %Z',
                      time.gmtime(email.Utils.mktime_tz(email.Utils.parsedate_tz( s )))),
        '%a, %d %b %Y %H:%M:%S %Z')
