Gmail Pop3 implementation

Before you dash off to try the example code, a warning though. Talking to mail servers even with JavaMail has pitfalls even with the FAQ to hand. For example, when I was writing this article, I decided initially to use GMail, Google's mail service and its POP3 support. Strangely though, Google's POP3 service is not RFC compliant which means as soon as you read a message from it, not matter what you do, that message will disappear from the message queue. With another mail server, the version of the server interpreted the RFC standard on authentication slightly differently causing a login error. How do you track down problems like this? One big help is turning on JavaMail debugging; when you get the Session, you can call the setDebug method to turn on debugging which in turn dumps everything that goes up or down the wire to the console. Be warned, when you are getting attachments, this can be some rather large sections of base 64 encoded text. Another way to flip the debug on is to set the system property "mail.debug" to true.

JavaMail has a whole range of properties which can affect the behaviour of providers. For example, with POP3, the standard provider has properties which control timeouts, authentication and how the provider actually interacts with the mail server. This in turn may resolve those compatibility issues mentioned above. These properties are provider implementation specific. Take the standard POP3 provider though; some POP3 providers automatically delete read messages when you disconnect, but the POP3 RSET command can reset the mailbox to its original read state. The property mail.pop3.rsetbeforequit set to true can enable that behaviour in the POP3 provider; the "pop3" part of the property name reflecting the provider's name, so change it to "pop3s" if you are using secure POP3. Here's code from the example which enables that for both and turns debugging on:

Properties props=System.getProperties();
props.setProperty("mail.pop3s.rsetbeforequit","true");
props.setProperty("mail.pop3.rsetbeforequit","true");
session=Session.getInstance(props,null);
session.setDebug(true);

And if you are wondering, no, this has no effect on Google Mail's POP3 implementation; once you've read it, it's gone. Next month, we'll look at using the MailRetriever as a servlet, complete with displaying those attachments, and look at handling some other types of mail beyond simple attachments.

The webkitTransform problem of iPhone 4G

On iPhone 4G
this.element.style.webkitTransform = translate(...) is very slow.

You should use
this.element.style.webkitTransform = translate3d(...)

看来不需要了，无法定位是因为越狱，已找到解决方法。

I have released a Cydia package that fixes the location services issue caused by the Spirit jailbreak.

1. In Cydia, add the source http://cydia.pushfix.info/

2. Install the package "iPad Location Services Fix"

That's it. It restarts locationd on install and on every boot after the SpringBoard finishes loading. You should have no more problems with location services after install.

Oracle数据库sys被锁定的解决方法

C:>sqlplus / as sysdba
alter user sys account unlock;
alter user sys identified by 123;
conn sys/123 as sysdba

这是采用操作系统认证的方式, 如果楼主也是你这种方式,不会存在他的问题,所以它和你的认证方式是不一样的. sys应该不会被锁定的，真是奇怪． 忘记密码的话，可以用命令orapwd重置sys密码，没必要重装． 用法如下： orapwd file=e:/oracle/ora90/database/pwdfox.ora password=sssssss entries=10; 如果你sys用户能登录数据库，其它的用户问题都好办了，它可以对所有用户进行设置．

How to make or compile a DEB in Windows

Tools:
iPhone or iPod touch
SSH (OpenSSH installed on device)
WinSCP (4.2.5 or higher)


1. Setup
First of all you would want to make a folder on your desktop. For this tutorial "X" is being used as a folder.

2. Control File
You will need a control file so you are able to package the DEB and for it to be viewable in Cydia/Rock.

To do this make a folder called "DEBIAN" (ALL CAPS) inside the folder "X".
Inside of the folder DEBIAN, make a file called "control" all lowercase and without an extension.

Here is a brief description of the fields in a control file
You need to add the below inside your control file except with your information. Make sure you add an extra space at the bottom of the control file

Code:

Package: com.yourcompany.yourapp
Name: YourAppNameHere
Version: Number
Architecture: iphoneos-arm
Description: Small Desc. about your app.
Homepage: Your Website
Maintainer: YourName 
Author: YourName
Sponsor: YourWebSiteName 
Section: System

Here is one of my own control file I use in Advanced Preferences

Code:

Package: com.csdev.advpreferences2
Name: Advanced Preferences 2
Version: B3-2
Architecture: iphoneos-arm
Description: This hack will give you more settings and tweaks. 
Homepage: http://www.csdev.2x.nu
Maintainer: CS Dev 
Author: CS Dev
Sponsor: CS Dev 
Section: System

3. File Structure
Inside your "X" folder, it's going to be like the iPhone File System. Like if you want to add a file to the root partition, just put the file in "X".

A. Application Structure
To install apps with DEBs, inside of "X", make a folder called "Applications". Then inside of Applications, make your app folder (EX: Cydia.app)

B. Theme Structure
To install themes wth DEBs, inside of "X", make a folder called "Library". Then inside of Libary, make another folder called "Themes" . After that inside of themes make your theme folder (EX: Cydia.theme)

Add your files using the structure above

4. WinSCP and SSH.

Open up WinSCP and connect to your Device. Navigate on your Device to

Code:

/var/root

Copy the X Folder to your device. File Structure should be below

Code:

/var/root/X

Inside the X Folder change the permissions of the DEBIAN folder and its files to 755
Navigate to var/root/ and open up the terminal im WinSCP. Do this by clicking the black box in one of the toolbars.

5. Terminal

Inside of Terminal type the following command in the "Enter Command" Box.

Code:

dpkg -b X.deb

It will pop-up some error and this is okay.

The DEB file will be located in var/root/

Code:

var/root/X.deb

All About Bikini Girl 被下线

周六晚开始进行“All About Bikini Girl”的免费促销，一时间盛况空前，服务器不堪重负。
周日下午改回收费时，不到一天时间被下载了5000左右，最高冲到US》Photography》Free的第8名，KR的第2名。光广告收入大概就有30多美元。真是好风光，好威风。
周一一早收到AppStore的邮件，看标题是“。。。Change Status”，本以为是某个程序又通过审核了呢，感叹了一下Apple居然周日（美国还是周日）还在上班，就兴冲冲地打开邮件。没想到居然是All About Bikini Girl被“Remove from sale”了，SHOCK！！！
联想到Apple今日打击色情软件的报道，看来自己是撞到枪口上了。杯具了。。。

现在正在思考对策
1.向Apple申述。（估计无效）
2.地下化，发非官方版本。

情人节免费促销

快到情人节了，今天把999 Roses和All About Valentine's Day给免费了。平时一天也不见得有一个下载的，免费后5个小时被下了300多个。不知是否能够上榜，等着看明天的日报了。

“All About Bikini”被宣传了

这两天一直再用Google的Adwords做广告，广告费到今天应该用光。因为没有在其它地方做广告，本以为流量会减到0，下午回来看了一下，居然还有流量。查了一下来源，发现是有一个日本的网站写了一篇“All About Bikini”的评论，真是活雷锋啊。

直接后果就是上了日本的Photography的Top Paid Apps，目前结果是97位。

All About Tiger Woods和All About Obama今天都上线了

All About Tiger Woods和All About Obama第一次申请是被拒，理由是含有“令人反感的内容”。无奈抱着试试看的心情写信给Apple申述，强调程序是图像搜索引擎，正如希拉里所说网络是自由的，我们不会过滤搜索结果。也没有修改程序就又提交了，只是说为了尊重Apple的意见，我们将会删除所提到的内容（实际没有删除）。今天居然全部通过了，真是神奇的苹果啊。
既然如此，过两天再试试重新提交一下杰克逊的，说不定也能过。

Apple to me

Thank you for submitting All About Tiger Woods 1.0 & All About Obama 1.0 to the App Store. We've reviewed All About Tiger Woods 1.0 & All About Obama 1.0 and determined that we cannot post these versions of your iPhone application to the App Store because it contains content that ridicules public figures and is in violation of Section  3.3.14 from the iPhone Developer Program License Agreement which states:

"Applications may be rejected if they contain content or materials of any kind (text, graphics, images, photographs, sounds, etc.) that in Apple's reasonable judgement may be found objectionable, for example, materials that may be considered obscene, pornographic, or defamatory."

A screenshot of where this behavior can be found within your application is attached.

If you believe that you can make the necessary changes so that All About Tiger Woods 1.0 & All About Obama 1.0 do not violate the iPhone Developer Program License Agreement, we encourage you to do so and resubmit it for review.

My reply

Dear iPhone Developer Program

Our application is an image search engine. What we do is just like
other image search engine.
We search the images from internet with some keywords. You can find
the same image in google image search with the same keywords. The
screenshots are attached(we use the iPhone with google image search ).

As Hillary Clinton said, we don't want to filter the search results,
too. But, We will delete the search result to show our good faith.
Please review it again. Thank you very much.

infrastructure will become what we and others make of it. Now, this
challenge may be new, but our responsibility to help ensure the free
exchange of ideas goes back to the birth of our republic."

希望该死的Apple早日解决问题！

因为这两天IDP帐号又出问题了，导致用户无法在App Store上下载1.01版，已经有用户开始直接给我写信了，看来还是有一定需求和用户基础的，呵呵。

希望该死的Apple早日解决问题！

一直在关注“klmaps”和“合众地图”等关键字的搜索排名，发现了一些规律。网站如果几天不更新排名马上会掉下去，更新一下又会提上来。有趣的是我更新的不是一个域名下的内容，只是两个站放在了一台服务器上。

Difference between Hibernate's get() and load()

If load() can’t find the object in the cache or database, an exception is
thrown. The load() method never returns null. The get() method returns
null if the object can’t be found.
