Java 技術論壇 - 安裝WTK 2.2的WMADemo 至P910i出現底下問題~~~
昨天就看到這個Thread ;) 我也試了一下,果然在安裝到P910i的時候就出現跟上面一樣的訊息, 去查了一下SonyEricsson的文件(Deploy J2ME in P910), 看到下面幾段話,
1)要在P910i上面執行WMA, 手機中的Phone Organizer的版本(就是開啟鍵盤蓋後選擇"編輯"->"系統資訊"後會看到的第二頁"個人助理"版本)要在CXC162021 R2B02或更高版本的才會支援
2) 在SonyEricsson的設計中, 有幾組API因為會耗用使用者的Air time, 所以被歸類在被限制的API, 包括JSR-120 WMA API
3)3GPP中設定的PORT值為16000~16999
猜想是因為WMA APIs 屬於被限制的API才會這樣
好吧，那既然我的手機版本是okay的, 那就自己Sign一下MIDlet suite好了, 所以我就到Utility sign一下, 果然...不會出現錯誤訊息了
--引用SonyEricsson文件的內容
An untrusted MIDlet suite is not trusted to use any of the restricted APIs without the explicit permission by the end user. At runtime when an untrusted MIDlet suite attempts to access a restricted API you are
prompted to accept or reject access to the specific API.
JSR 120, Wireless Messaging API 1.1 is implemented with support for SMS send, SMS receive and Push-Registry Alarm. MIDP 2.0 security has been added to the Open connection, Send and Receive functions,as specified in WMA 1.1.
Note:
WMA is supported only in the Phone Organizer SW version CXC162021 R2B02 or later.The 3GPP specification for SMS specifies the port numbers 16000-16999 as available for applications. It is recommended that Java developers use non-reserved port numbers within this range. The WMA specification has a system list of restricted port numbers which may not be used by the Java application. For compatibility with other WMA supported mobile devices, it is recommended that you use non-reserved port numbers.

Team Server 2005 from .NET Developer's Journal
.NET Developer's Journal: "Team Foundation: At Work
Version control, work item tracking, project management, and build management
January 12, 2005
Summary
Do you find yourself tired after sitting in meetings all day? Do you have feelings of uselessness after weeks of bug fixing? Do you often find yourself feeling lonely, as if you've lost touch with your team and the status of your project? Are you frustrated by frequent fire drills and the sense that your project is in utter chaos? Are you hopelessly lost in a sea of changing policies and procedures with no end in sight?
If you answered yes to any of these questions, you may be clinically depressed and require extensive psychological counseling. Or maybe, just maybe, you are using the wrong software life-cycle tools.
As part of the Visual Studio Team System 2005 release, Microsoft will introduce a new server product designed specifically to improve software team collaboration and increase individual productivity. This new product is called Team Foundation (TF). This article discusses the key objects created and managed by software teams, why the integration between these objects is so important, and how Team Foundation can help your team be more successful.

Backed by powerful technology groups and a handful of artists, file-swapping software companies on Tuesday asked the U.S. Supreme Court to reject proposals from the entertainment industry that could put them out of business.
Record labels and Hollywood studios, seeking to overturn lower court rulings shielding file-swapping companies, have asked the court to rule that businesses distributing products 'predominately' devoted to copyright infringement should be held legally responsible for that illegal activity.
That prospect has drawn staunch opposition across the technology sector. Intel, trade associations representing consumer electronics and software companies, and consumer groups joined the file-swapping companies on Tuesday, asking the court to avoid creating a new legal test they said might stifle technological innovation.
'The ability to create and innovate is a dynamic process and...not every society has achieved the mechanisms and balance and capability to achieve what we've done,' said Ed Black, president of the Computer & Communications Industry Association. 'It is that delicate balance that content owners are threatening to throw off.'
The Supreme Court case is one of the most closely watched issues across the technology and entertainment realms this year, with both sides saying that an unfavorable outcome could be devastating to their respective industries.
At the heart of the case is the 20-year-old Supreme Court ruling that made Sony's Betamax videocassette recorder legal to distribute without liability, despite its use by consumers to record and save copyright movies and TV shows. In that ruling, the court said that com"

殺手級超大尺寸LCD：Dell 2405FPW
CNET電腦專區/洪仁偉 2005/03/01
LCD可以說是在這兩年來價格波動最劇烈的資訊產品之一，2002年底時，LCD主流呎吋仍是15吋，而售價大約1萬元，當時17吋LCD售價在15000元以上，2003年底17吋LCD已經躍升為主流，售價跌至萬元左右。
劇烈的價格下滑在去年底依然重演，在2004年資訊月19吋LCD雖然跌破萬元的機種不多，但平均主要品牌售價已經約在12000元-13000左右；15吋、17吋當然更便宜，如果選擇比較沒有知名度的品牌，15吋LCD甚至5000元有找。
相較於廝殺激烈的15、17或19吋等LCD主流尺吋機種，過去專門銷售給專業美工或設計人員的20吋以上LCD價格就相對顯得比較穩定，20吋的LCD售價大約要3萬元以上，雖然和19吋相差1吋，但售價幾乎要1倍以上，而更大尺寸的LCD，例如相當受專業設計人員歡迎的Apple 23' Cinema HD Display還要價接近7萬元。
不過隨著LCD上游原料產能的增加，大尺寸LCD似乎也無法自外於這股LCD平價風，Dell近日就推出一款解析度1920x1200、亮度500cd/m2、反應時間12ms規格的24吋寬螢幕LCD 2405FPW，而且它的售價僅3萬7千元。
雖然相較於1萬多元的19吋LCD，Dell 2405FPW還是有點貴，不過比起以前動輒5、6萬以上的超大尺吋機種，已經便宜不少，而且規格也沒縮水，或許這些超大尺吋機種將是下一個LCD價格戰場。"

Matt Stephens and Doug Rosenberg (co-authors of eXtreme Programming Refactored: The Case Against XP) wrote 'The Irony of Extreme Programming' for the latest Dr. Dobbs Journal (which you can also get online with a membership).
They point out some of the things that I have thought for a while: eXtreme Programming (XP) has a lot of nice ideas, and it mitigates some problems, but it is neither a religion or a cure-all. In fact, it can create some problems of its own if not used well.
I like that they step back from the hype to look at some of the problems. I think the programming world (or maybe just the world, unqualified) tends to get too caught up in using a particular process or technique, even if common sense says something else. I have often told those close to me that if they cannot criticize their favorite thing, they do not know it well enough.
They quote an email one of their readers sent them:
The pair programming is mind numbing. With this XP stuff, software development is no longer a professional occupation, it's just another type of assembly line work.
Different people have different ideas about that, and as I write this from Detroit, home of the Henry Ford Museum, I wonder if those great innovations I learned in elementary school, like division of labor and the assembly, caused the same reaction. I would certainly expect that demoting a master craftsman to the assembly line would cause some problems, so why do some shops insist on doing that to senior developers just so they can say they practice XP?

Cryptographers to Hollywood: prepare to fail on DRM [printer-friendly] | The Register
Cryptographers to Hollywood: prepare to fail on DRM [printer-friendly] | The Register: "Cryptographers to Hollywood: prepare to fail on DRM
By John Leyden (john.leyden at theregister.co.uk)

RSA 2005 Movie industry representatives at RSA 2005 in San Francisco today called on the IT industry in thwarting illegal file sharing before the problem threatened its revenues. But they were told that they must recognise the limitations of digital rights management their fight against digital piracy.
Speaking on the RSA conference panel Hollywood's Last Chance - Getting it Right on Digital Piracy, Carter Laren, security architect at Cryptographic Research, noted that cryptography is 'good at some problems, such as transmitting data so it can't be eavesdropped or even authentication, but it can't solve the content protection problem. If people have legitimate access to content, then you can't stop them misusing it.
'Anyone designing content protection should design for failure and if it fails update it,' he added.
John Worrall, marketing VP at RSA Security, agreed that content protection systems should be easy to upgrade. The entertainment industry must also learn from its previous mistakes in pushing the weak CSS copy-protection system for DVDs: 'If content providers open up standards to good cryptographic review they will get a better system,' he said, to applause from the RSA 2005 audience.
The entertainment industry also needs to be responsive to changing market conditions and consumer preferences, according to Worrall: 'Don't lock down a set of content rules that look draconian five years from now. Be flexible enough to incorporate change in rules. If rules are too restrictive people will go to other channels, including pirated material."

Embedded.com - Software synthesis for embedded systems
Embedded.com - Software synthesis for embedded systems: "Software synthesis for embedded systems
By Bob Zeidman
Embedded Systems Programming

Synthetic operating systems might mean never having to port software again. Software can be automatically generated-synthesized-to meet the demands of a changing system.
For decades hardware design began with a schematic-a graphical representation of the hardware that could be turned into components and wires, a printed circuit-board layout, or a semiconductor chip. At first the process was done manually with hand-drawn schematics that were translated to layouts by highly trained draftsmen. The process was later automated with schematic-capture tools, automatic netlist generation, and physical-layout programs, though the concepts remained the same. Eventually, chip designs grew very large and a new design method was needed. Thus was hardware synthesis born.
Hardware-description languages (HDLs) similar to programming languages were developed and now all chip designs begin as lines of code. The code is written at a high level that hides much of the complexity from the designer, and then is synthesized into a low-level description for layout and analysis. I'm proposing that the time is right for a similar evolution in embedded systems software design.
Synthesis is the process of taking a high-level description and turning it into a lower-level description that, in the case of software, can be compiled directly. By working at a higher level, the user is kept uninvolved with implementation details. Synthesis employs automatic code generation (ACG) but there's more to it than that. Some popular and useful code-generation tools already exist. Microsoft Visual Basic and HTML-layout tools like Macromedia's Dreamweaver allow users to create graphics and buttons with little or no knowledge of the underlying code. These kinds of ACG tools are indispensable for creating a user interfa"
