[AIR] MLB.com 推出desktop app
Majro League Baseball 利用了adobe air 的技術完成一個desktop application。
功能上:news,favorite,scores,schedule (都是一些簡單的content),再加入social network 的元素:直接post to twitter。
所以話呢,chowky暫時見不到有公司的新app是利用了silverlight。用來用去都是M$自己

[White Paper] 文章分享 USING OPEN-SOURCE SOA IN AN ENTERPRISE DEPLOYMENT Reducing costs, lowering risks, and increasing flexibility
Sun 主力是賣hardware的,再配搭opensource的軟件。
所以會有很多研究闗於opensource怎令enterprise 下調成本。
當然這篇文章,對於IT with Business 有興趣的朋友就一定會很悶的。因為是非常business,這是service-oriented architecture (SOA)
Many companies are turning to a service-oriented architecture (SOA) approach to use their existing IT assets in new ways. Application functionality is made available as a service, available to all applications that use that particular capability. Business managers know that an SOA is a key technology in business integration, and can help increase agility, improve customer satisfaction, and increase responsiveness.
[iPhone] Ads? Charge? Case Study of iPhone 遊戲 「Galaxy Impact」
chowky 向來都有留意iphone developer 有關的新聞,消息。(想加入就要花時間,想賺錢,當然要付出)
對於一個developer來講,賺錢的方法不外乎賣廣告、直接收費。雖然有另外有新的玩法,subscription 訂閱的方法(只限於3.0)。當然這只是講最直接的方法。有其他的請告知。
當developer完成一個新的app應該點做?develoepr 跟本無錢做 marketing,這個case study應該對你有幫助(至少對chowky有),對於strategy上都有幫助。
當然這只限於game方面的apps
Galaxy Impact 是一個經典類型的撞磚game。
這隻game 在 27-10-2008 開始特價(免費),之後首兩星期有大概有220,000 downloads,之後變成No. 10 in “Top Free Apps” in Game Category and No. 20 in “Top Free Apps” 。
在變為$0.99 fee for purchases on 09-11-2008。
Microsoft「歧視」黑人?

美國都已經出了第一位黑人總統,但作為美國軟件巨擎的微軟公司竟帶頭「歧視」黑人?
事緣有網友「揭發」微軟在其官方網的宣傳照片造假,將相中人黑改成白,但就唔記得改隻手的膚色,所以「穿崩」兼引起「種族歧視」的嫌疑,微軟應該繼「培訓」員工如何「重新包裝」iPod外,重點加強他們使用Photoshop的技巧呢!

[Flex] 利用 actionscript 去 load 其他的 swf
Flash 是允許 developer load 外部的 SWF files (當然也可以是 images,JPG, PNG, GIF) 這種做法其實是有好處的。
- 不同的swf file 可以跟次序地播。而又不用reload browser or pause the pages.
- 相比於一個很大的swf,能夠有效地分開一個個細小的swf file,一來可以load 得快,memory 的處理亦會比較好一點。
- 一個複雜的user interface 當然不可能單靠一個的swf file。(尤其download了不同componet的developer。)這個程況就可以靠load其他external 的swf 去解決,一邊可以容易一點manage,修改一個不會影響整個flash的控制。現在很多devleoper都支持component base 的design。而且可以加容許不同的developer一齊去做各自的ui部份。
如果要 load external 的 swf 有以下三種方法
* Using the ActionScript 2.0 loadMovie command
* Using the ActionScript 2.0 MovieClipLoader class
* Using the ActionScript 3.0 Loader class
chowky 對actionscript 2.0 無興趣,所以只看了3.o,有興趣可以自己看看原文
Loader 在 actionscript 3.0 是subclass DisplayObject
用法很簡單,只要利用load這個method就可以了。
var myLoader:Loader = new Loader(); addChild(myLoader); var url:URLRequest = new URLRequest("myExternalMovie.swf"); myLoader.load(url);
url 可以是absolute path 或者是relative path。
但還有很多要注意的地方 Read the rest of this entry »
[Flex] 怎利用 flash cs4 來export flex 可用的library
剛剛 chowky 就利用flash 來寫一個website 出來,所以就找下很多不同的flash的東東。無意之中就找到這個flash cs4 的教學。
不過flash cs4 其實真的不可能用來開發大型的project,因管理(maintenance)方面真是令人頭痕。所以可以把兩方面合
作就非常好了(哈,開發成本都高了很多)

[Flex] Adobe Opensource its Flex Charting Component
Posted by Chowky in FLEX, Opensource, RIA on August 28, 2009
估不到,因為什麼原因而opensource自己的charting component,這會否影響了flex builder 3 professional 的銷情?
That page also has the Data Vis. components listed, and the download includes the source and is no longer watermarked.
Previously a Flex Builder licence was required to obtain the source and remove the watermark.
可能坊間太多不同的charting component,所以adobe 索性open source。
不過都是一個好消息。~

Nokia mobile payment 上的解決方案 — Nokia Finance
先前nokia 向 obopay 買入preferred share,當然是一個策略性的合作關係。
nokia money 這個platform 是建基於obopay 的mobile payment的方法。
4 billion mobile phones but only 1.6 billion bank accounts
“We believe mobile financial services offer a market opportunity with long term growth potential. In many countries, mobile phone ownership significantly exceeds bank account usage, suggesting that many mobile phone users have very limited or no access to basic financial services. With more than 4 billion mobile phone users and only 1.6 billion bank accounts, global demand for access to financial services presents a strong opportunity to combine mobile devices with simple but powerful financial services such as Nokia Money”, said Mary McDowell, EVP and Chief Development Officer, Nokia.
這樣當然可以代表有很多growth opportunity。但是要改變用戶的shopping behaviour,其實都不簡單的。
不過如果不建立這些infrastructure的話,就會有其他人做類似的事,到時就失去先機了,(即是無得選擇,一就淘汰別人,一是被人淘汰,已經不能原地踏步)
