OSX|看avi影片不再头痛[转载]
| |
虽然苹果推出Quicktime 6支持播放MPEG-4格式的影片，但是还有一些avi格式的影片需要借助第三方工具来播放。至于什么是MPEG-4，什么是DivX，什么又是avi？我们会在文章后面做个补充。 www.6park.com
那么，有什么方法可以欣赏到精彩的avi影片呢？ www.6park.com
方法一：用DivX Doctor II+3ivx Delta 4.0 PR1＋Quicktime组合
方法二：用VideoLAN Client（简称VLC）
方法三：用MPlayer X
方法四：用DivX 5.0 Alpha www.6park.com
方法一：用DivX Doctor II+3ivx Delta 4.0 PR1＋Quicktime组合. www.6park.com
方法是将3ivx Delta 4.0 PR1中的3ivx D4 PR1 Decoder OSX放入~/Library/QuickTime目录（MacOS X)或3ivx D4 PR1 Decoder OS9防入System Folder/Extensions/QuickTime Extensions目录，重起Quicktime 6 Palyer。然后用DivX Doctor II将DivX .avi 格式的影片转为3ivx QuickTime (.mov) 格式，这样，就可以通过Quicktime Palyer来流畅的播放了。 www.6park.com
将avi影片拖入DivX Doctor II的窗口中，点按Start来将其转换为mov格式。虽然这个方法有点复杂，但效果却非常好。 www.6park.com
下载DivX Doctor II:
http://doctor.3ivx.com/download/divxdoctor21.sit www.6park.com
下载3ivx D4 4.5.1 for OS X: http://www.3ivx.com/codec/3ivx_d4_451_osx.dmg www.6park.com
方法二：用VideoLAN Client（简称VLC). www.6park.com
VLC能播放VCD, DVD, MPEG(1, 2, 4) 和 DivX文件，不得不提的是VLC在MacOS X上播放影片非常出色，包括Quicktime不能播放的VCD，并支持全屏播放。 www.6park.com
VideoLAN Client的另一个特长是可以在配置DVD-Rom的Mac上播放DVD影片，更厉害的是用VCL播放DVD时，可以用通常的"苹果+Shift+3(4)"来截取DVD影片画面，这点比系统内置的DVD Player要来的方便的多。 www.6park.com
下载VLC 0.7.2 for MacOS X:
http://download.videolan.org/pub/videolan/vlc/0.7.2/macosx/vlc-0.7.2.dmg www.6park.com
方法三：用MPlayer X. www.6park.com
MPlayer是由LINUX平台改写过来的播放器，支持MPEG, VOB, AVI, VIVO, ASF/WMV, QT/MOV, FLI等格式。由于LINUX的身世，开始播放时会利用Apple ***自动启动Terminal执行一些指令(管它干什么）。支持全屏。但不支持非英文文件名包括路径，比如你你影片a.avi在中文名的文件夹里，也是无法播放的，在光盘里的话，要将文件夹拷贝出来改为英文名。(未在MacOS X10.2下测试). www.6park.com
下载MPlayerOSX:
http://www.ipodrock.com/download/MplayerOSXB8.zip www.6park.com
方法四：用DivX 5.0 Alpha www.6park.com
www.divx.com推出的DivX也是不错的工具，安装好后的DivX Validator能将MPEG-4的DivX AVI文件转为QuickTime 能正常播放的文件。转换的速度也非常快，在G4 733上转换160MB的avi文件用时不到1分钟。画面和音质也相当不错。 www.6park.com
DivX for Mac同样支持拖放，可以将DivX AVI文件转换为一个DivX图标的影片文件，用Quicktime播放这个影片就可以了。 www.6park.com
下载Div X:

补充： www.6park.com
1) 什么是 DIVX-MPEG4？ www.6park.com
DIVX 视频编码技术实际就是 MPEG4 压缩技术，它可以说是对上挑战 DVD 对下力压 SVCD ，其对 DVD 和 SVCD 造成威胁不容忽视（有人说它是 DVD 杀手），它由 Microsoft mpeg4 v3 修改而来，使用 MPEG4 压缩算法。 www.6park.com
2) 什么是DivX？ www.6park.com
要回答这个问题，可要追溯到MPEG的标准，MPEG本是Moving Pictures Experts Group（运动图像专家组）的英文缩写，这个专家组始建于1988年，专门负责为CD建立视频和音频标准，在开始的时候建立了四个版本:MPEG1～MPEG4，分别适应于不同的带宽和数字影像质量的要求。DivX就是一种MPEG4编码格式，它的原型是微软的MPEG4编码，只不过旧版的MPEG4编码不允许在AVI文件格式上使用，才会有DivX编码格式的出现（不过微软在MPEG4编码的第二个版本中已经取消了这个限制，使用上也和DivX毫无二样）。 www.6park.com
不过现在国内外称呼的DivX已经和传统的DivX不一样了，它指的是MPEG/MP3影片，具体意思就是影像部分以MPEG4格式压缩，Audio部分以MP3（MPEG-1 Layer 3）格式压缩组合而成的AVI影片 www.6park.com
它的好处是生成的文件体积小， 约为同样播放时间的DVD的1/5到1/10， 但是声音及影像的品质都相当不错，当然比DVD还是差一点，但比起VCD要好得太多了，也就是说DivX只要一张光盘就可以放下一个90分钟的电影，而且清晰度要比两张光盘的VCD好许多！ www.6park.com
3) 什么是AVI？ www.6park.com
AVI即 Audio Video Interleaved，是微软公司推出的视频格式文件，它应用广泛，是目前视频文件的主流。 这种格式的文件随处可见，比如一些游戏、教育软件的片头，多媒体光盘中，都会有不少的AVI。

Wisdom|有效领导的一种重要策略
一个规模较小的新组织有多大的可能性推翻基础牢固的得到公认的旧统治阶级？这个问题不仅仅与军事政变有关，它也与政党控制国家舆论，新的产品取代市场上的畅销产品等息息相关。华中科技大学控制科学与工程系副教授、剑桥大学高级研究员张海涛（Hai-Tao Zhang）博士和同事探讨了这一问题，透露了有效领导的一种重要策略。 他们建立了一个计算机模型，一群个体跟随在领导者后面，朝着固定的方向――右边――前进。这时一个数量较少的群体试图让其他人和他们一起向相反的方向――左边――前进。乍一看他们的成功机会并不大。研究人员识别出了两种决定结果的新领导特质：其一是在既定时间内尽可能的传播新领导者的影响力；其二是有足够的说服力去进行变革，并让受影响的跟随者坚贞不移。张海涛和同事的研究指示，只要优化传播模式，即使人数比对手少，新的群体能打败旧统治阶级，他们将能取得权力或至少赢得一席之地。这项研究或能解释最近几年涌现的基于互联网的基层运动，包括政治和商业。当然互联网时代，统治阶级的反扑和如何维护自身地位也是值得注意的。

OSX|Unix Programs, Freeware Made Easy on OS X
Unix Programs, Freeware Made Easy on OS X
Introduction
This website is merely a series of notes that I have made for my own use which I have decided to share over the internet. I have made them as easy to follow as possible so that anyone, myself included, can follow them without too much trouble. The notes are aimed primarily at using software freely available to the Mac platform, much of it unix-based, "open source" software. The documentation on many of these programs is woefully inadequate. Through a process of trial and error, I have figured out how to use some of these applications. Since I have a tendency to forget the discoveries I have made, putting them on the web is useful for myself and, I hope, others as well.
Although all the procedures documented in the tutorials on this site have been tested, there is no guarantee that they will work on other Macs. There may be any number of reasons why you might have problems. So it is best to experiment to make sure they function as advertised before using them in a critical project.
Installation
Before we start, a word about installation. Most of the programs we will be using are not hard to install — if you know how to do it. A program developed by the Open Source community called Fink not only compiles and installs all the programs you will need, it even finds them on the internet and downloads them for you. When used in tandem with the OS X program FinkCommander, it makes installing unix software almost as easy as using the OS X Software Update. For information on how to install and setup Fink, go here.
One thing else note. There exists a terrific program called On My Command which allows one to access command-line Unix programs from the convenience of a contextual menu. Go here for a tutorial.Audio
We'll begin with a glance at some Unix audio programs. The programs that are used in this site's tutorial are:
- sox
- normalize
- mpg123
- lame
There are three other programs we'll be needing which, although not "Unix" programs, nonetheless are free:
- Audacity
- iTunes
We will use these programs to:
- Convert audio files from one format to another
- Edit sound files
- Equalize volume level of selected files
- Flatten dynamics with compand filter
- Subject audio files to a variety of filter effects
- Use Unix batch commands to improve workflow
CD Burning with cdrtools
For most of your burning needs, iTunes and the Finder will provide you what you need. But for those special tasks, cdrtools can sure come in handy. The programs we will use at this sites tutorial are:
We will use these programs to:
- cdrecord (part of cdrtools package)
- mkisofs (part of cdrtools package)
- cdda2wav (part of cdrtools package)
- X-CD-Roast (GUI for cdrtools)
- disktool
- iTunes
- Disk Copy
- sox
- Create multi-session data CDs
- Erase CD-RWs, including individual tracks
- Extract multiple audio tracks into single file
- Copy CDs and CD-ROMs
- Use X-CD-Roast to access power of cdrtools
- Automate certain functions of cdrtools
Publishing and Layout
Here our aims, to start out with at least, will be relatively modest. The programs we'll use, as before, are all available for free:
- ps2pdf
- tiff2ps
- tiffcp
- lyx
We will use these programs to:
- Setting up PDF Services
- Create multipage pdf files out of tiff images
- Experiment with the lyx word processor
- Configuring LyX keyboard bindings
Html tools
The aim here will be on utilizing free tools for building webpages. The software we will use involves a mixture of unix and Mac OS X programs:
- Mozilla Composer
- NVU
- Bluefish
- JAlbum
- QuickImageCM
- iPhoto
Internet
The focus of this section of the site is not so much to make or alter files, but merely to make use of various unix web browsers, as well as other internet utilities from the unix universe. We will make use of the following programs:
- wget
- lynx
- gtk-gnutella
- pan
- dillo
- mozilla
Our main focus in this section will be on using these utilities to save time — either time in surfing or time on the internet.
Word Processing
For those who bought their Macs before Apple upgraded to Appleworks 6.0 and are looking for a word processor that works in OS X, the following programs represent your best bet:
- Open Office Writer
- KWord
- Abiword
- TextEdit
We will compare the advantages of using each of these programs with their disadvantages, indicating the most efficient methods of using them in combination to get specific tasks accomplished.Utilities
Years of using Apple's pre-OS X systems has conditioned a number of Mac users into believing that commercial utility programs such as Norton Utilities or Tech Tool Pro are an absolute necessity. But this is not necessarily true. In the first place, Unix does not have the stability problems associated with earlier incarnations of the Mac OS. You don't need constantly take care of it to keep it from imploding on you. In addition, there are a number of unix or unix-based freeware programs that will take care of most, if not all, your utility/service needs.

Thought|库班说兴于免费，衰于免费
互联网: 库班说兴于免费，衰于免费
达拉斯小牛队老板，互联网企业家库班（Mark Cuban）认为，如果一家企业是基于免费的商业模式，并因此而大获成功，但是成功是不可能一直依赖于免费的，依靠免费的时间越久，它付出的金钱成本便越多，最后总有一家也是基于免费商业模式的新企业来取代它，所谓兴于免费，衰于免费。 这种事情一直在上演，如Facebook取代Myspace，或者Myspace取代Friendster，或Google取代Yahoo。这也是为什么Google一直到处投资，寻找另一个未来“Google”的真正原因。库班称，任何一家因为免费而获得成功的企业，都应该尽可能快的转向能产生盈利的事物上，“当你因免费而成功，你也将因免费而死亡....不要反抗，要承认，去获利”。

Brain|速解祕笈
Google Image Result for http://ten10.myweb.hinet.net/lbl/lbl.jpg
速解祕笈
速解魔方是從何時開始的？已經難以考證。然而，速解魔方肇始於愛好者已經能夠熟練的復原魔方，因而不再只是追求復原六面，向上一層樓，開始追求最快的還原。慢慢地，速解逐漸成為眾多魔術方塊玩家所共同追求的目標。
然而，許多人都卡在一個問題：「我如何更快復原？我應該練什麼？需要加強哪裡？」當你遇到迷惑而不知如何進步時，你必須先了解自己的實力在哪裡，才得以對症下藥。
以下是最佳的魔術方塊學習順序，請循序漸進的學習！
※如果你復原魔方平均90秒以上……
請本站的LBL基本解法開始學起，並培養正確的觀念：「魔術方塊是一層一層解，而不是一面一面解！」
LBL基本解法只需記憶五、六個公式即可復原魔方，入門容易，極適合初學者。
一般人在熟練LBL基本解法後，可達到一分鐘復原的水準。
LBL基本解法共有七個步驟，如下： （點選圖示可以進入教學）
當你學會了LBL基本解法後，復原魔方仍然花兩分鐘以上，表示你LBL基本解法並沒有熟練，依舊太生疏。
請多加練習，以加強你的判斷，減少你停頓的時間。
※如果你平均90秒內復原魔術方塊……
可以將原本需花三次到五次左右的OLL，全都壓低為只需兩次。
兩段式OLL學習完畢之後，開始學習「兩段式PLL」（７個公式）。
把原本需花兩次到四次的PLL，也都壓低為兩次，且有31.94%的機率可以一次解決。
兩段式的公式不多，又能大幅縮減秒數，非常划算！
LBL基本解法＋兩段式OLL＋兩段式PLL＝＝＞理想秒數：４０秒！
※如果你平均40秒內復原魔術方塊……
請先把「PLL」全背下來，共２１個公式。至此，PLL終於畢業，全都一次ＯＫ！
PLL學習完畢之後，開始學習「F2L」（４１個公式）。
注意！F2L絕對不可死背，必須理解。
F2L是將第一層的角塊跟第二層的邊塊同步處理，非常有效率！是CFOP速解中最能大幅進步的。
不過，當練熟F2L之後，你不再是初學者了，已有成為魔術方塊達人的潛力。
Cross＋F2L＋兩段式OLL＋PLL＝＝＞理想秒數：２０秒！
※如果你平均25秒內復原魔術方塊……
並將加強四對F2L的銜接，目標是零停頓的判斷。
讓F2L看起來像是一次完成，而不是：做第一對，停，做第二對，停，做第三對，停，做第四對，停
以及只看頂面與兩個側面即可判斷出OLL、PLL。
Cross＋F2L＋OLL＋PLL＝＝＞理想秒數：１５秒！
| 所學習的項目 | 理想秒數 |
| LBL基本解法 | 60秒 |
| LBL基本解法＋兩段式OLL＋兩段式PLL | 40秒 |
| Cross＋F2L＋兩段式OLL＋PLL | 25秒 |
| Cross＋F2L＋OLL＋PLL | 15秒 |
建議(Suggest)
１、給自己錄影，比較自己和高手的差距。
２、要多和高手交流，從他們身上你能學到很多東西。
３、不僅要學習速度，還要學習魔方數學、盲擰、最少步數完成。
４、試著在有別人圍觀的情況下玩魔術方塊，因為自己平時都在家練習，在表演給別人看的時候，心理肯定會緊張。
５、參與網上的討論。
６、嘗試學習一些其他的方法，或許你能從中找出一些新的靈感。
７、記住一個打亂公式，然後去復原魔方。這樣你就能比較出你在放鬆和有壓力的情況下，你的成績會有多大波動。
理論時間(Theoretical Average)
理論上的平均時間：在CFOP系統中，復原一個魔方分為七個步驟。Cross+ 4*F2L+ OLL+ PLL。在復原時，分別計算這些時間然後將它們相加。
因為在實際過程中，你不可能做到100%的不停下來觀察。所以這個方法的目的就是。計算出理論時間和實際的時間，如果你的理論時間要大大的少於你的實際時間，那就說明，你浪費了很多時間停下來觀察，這些時間都被浪費了。你有很大的潛力可挖。這個時間差很小，你的成績還是不理想，那麼你要考慮看看是不是公式的問題了。

iphone|SSH Tunnel on iPhone
SSH Tunnel on iPhone - neophob
I need a SSH tunnel on my IPhone, so I can access my devices at home (for example dreaMote to access the dreambox).The easiest way I found to do this, was by using MobileTerminal. I just added a new menu entry, which points to a script:
Add menu entry to MobileTerminal:
Execute the script:
The simple script:
Now you can exit MobileTerminal (press the home button) - the SSH tunnel still exists!
The simple script:
iPhone:~ root# cat /private/var/myscript
#!/bin/bash
ssh user@your_server.org -L 5000:192.168.111.24:80Now you can exit MobileTerminal (press the home button) - the SSH tunnel still exists!

Screencast 2: Logging in Django, for fun and profit
« Screencast: Debugging with the Django Error Page | Using pdb, the Python Debugger (Django Debugging Series, Part 3) »
This is the second screencast of a week long series.
So that I don't spam all of the Django Community Feed (Bad RSS handling has done that more than once, Sorry!) I'm only going to be posting this post and the last post summarizing all of the screencasts on the aggregator. So if you're trying to keep up with all of the screencasts that will be coming out this week, either stay tuned to the site or subscribe to my feed.
Screencast 2: Logging in Django
Setup
This screencast is going to be about how to use the python logging module in Django. It's in the Python standard library, so there is nothing extra to install to use the simple python logging module. The screencast also makes use of the excellent Django-Logging, which should be downloaded and installed beforehand.
svn checkout http://django-logging.googlecode.com/svn/trunk/ django-logging
This allows for you to follow along on the second part of the screencast. I also do a little bit of work inside my django-testmaker app, so you can go grab that if you want to follow along as well. If not no big deal, the screencast is more about general logging anyway.
Video and Download
The video is available to download in higher res or for streaming.

Screencast 2: Using Logging in Django from Eric Holscher on Vimeo.
Writeup
Part 1: python logging module
We start out with some really simple logging methods. The first is a simple print statement inside of your views. This outputs the command to the terminal in your development server. The next way to do it is with a simple logging command:
import logging logging.error('your error goes here!') During the screencast I say that logging.error goes to Standard Out, when in actuality it goes to Standard Error. In this case they're the same thing...Then I go through how logging is done within the testmaker app. This is the basic setup for python's logging module that I used:
logging.basicConfig(level=logging.INFO, format='%(message)s', filename= "/file/to/log/to", filemode='w' ) More documentation about this and the python logging module is available here It includes a lot of really good information about the logging module, like lots of message formatting options. I show how you can tail a log file from testmaker and talk about the neat advanced features of the logging module like logging across a network. As you can see the logging module is very powerful!
Part 2: django-logging
In the second part of the screencast we show how to use the Django Logging middleware. This is what is going to go into your settings_debug.py:
from settings import * DEBUG = True INTERNAL_IPS = ['YOUR.IP.HERE'] MIDDLEWARE_CLASSES += ('djangologging.middleware.LoggingMiddleware',) LOGGING_LOG_SQL = True This then has all of your logging output appended to the bottom of the page you're currently on. This gives you a similiar capability of using the error page to debug, except you don't have to have an error. You can debug while the pages are still working.
The next and last really neat feature is showing the SQL queries that are being executed to render a page. This is incredibly useful for fine-tuning your django sites. With the ORM, there are tiny little tweaks that you can sometimes make to decrease (or increase!) the numbers of queries you execute pretty dramatically. Having this enabled during development is a good way to catch those mistakes, and really understand what is going on under the hood of your Django apps.
Remember, when you wrap all of your logging stuff in the logging module, you can do some really neat things after the fact. I was able to use all of the django-logging stuff while still logging output to a file and whatever else happened to be going on with the logger at the time. This in incredibly powerful, and allows you to almost have django-style 'pluggable logging backends' that do different things.
Again in this one I end a little silly: Thanks for your time and have a good day (since I'l hopefully see you again tomorrow :))
News|新华社英文节目进入欧洲超市
互联网: 新华社英文节目进入欧洲超市
今年4月份，中国宣布将鼓励媒体进军海外，至今中国已经推出了《环球时报》英文版，扩大了《人民日报》的业务，并计划推动中央电视台(CCTV)与CNN、BBC和半岛电视台等海外电视台展开竞争。 《华尔街日报》报道，新华社将在欧洲超市播放新闻节目。新华社正在跟十几个欧洲电视机构合作，每天推出英文电视新闻，在欧洲超市里的电视屏幕以及中国驻欧洲使馆外的电视屏幕上播出。新华社这个90分钟的节目定于周三开始播放，其中包括了10-15分钟的新闻报导以及特写和生活休闲节目，所有节目都将由新华社在北京的演播室里面录制。此举被认为是加强中国软实力的最新举措。
