看看與 Symbian 相關的 Kindle 書價錢(美元計,暫時有11本書):

Print $80, PDF $75, Kindle $62.00 (saved 23%)

假如要買晒以上所有的書,印刷本是 $850 另外數以公斤計的運費;電子書就是 $755;Kindle 書是 $553.41,比電子書平宜 26.7%、比印刷書平宜 34.8% 並省了運費,但加上機價 $279,合共 $832。
(850=110+80+75+60+65+60+60+115+75+70+80)
(755=90+75+70+50+65+50+55+95+70+60+75)
(553.41=74+47.21+53.52+42+37.79+32.24+39.44+74.79+53.14+37.28+62)

無論哪一個版,合計價錢在 $750-850 之間,平均一本書都要 $68-77 (HKD$530-600),做書蟲都很花錢呢。

若考慮到「實質」的分別,可能會讓人 Kindle 更感興趣。11本印刷書起碼佔了大半層書櫃(除非大書櫃),攜帶又極之不便,長遠還會甩頁、摺角、變黃等。電子書是方便傳送,但閱讀卻比較麻煩,閱讀時需要電腦、iPhone、Windows Mobile VGA 等,撘載 QVGA 240x320 的螢幕跟本不能看這些 PDF 文件,其實 iPhone 也很勉強。不比 Kindle 方便,除非有一台 tablet 吧。

Kindle 真是幾吸引。問題是,我是否一個「讀書」人呢?

N82的5MP相機小技巧

某次去婚宴,談起場地的那個吊燈,雖然周圍不是很光亮,但用 Nokia N82 拍下來還是太光,看不見發光的主體:水晶吊燈。

如果有比手機更好的相機,當然可以調校快門光圈之類,就可以把吊燈攝下來,但如果手上就只有一部手機呢?
其實是相機感受了周圍的光(光不足),然後自動拉長了快門所致,所以最簡單就是向主題放大(Zoom In),減低受周圍光線的影響。

至於像最不足,這是相機本身的問題。

Symbian Controls & Sub-Controls

最近想做一個仿標準的 control,網上有很多 resource/post,其中有幾個可以參考:
Quartinus’s Blog - Symbian UI
自定义控件

而 CCoeControl 裡提供了一個 Components(),用來收集其附屬的 component controls,利用它就可以省去寫 TInt CCoeControl::CountComponentControls() const 和 CCoeControl* CCoeControlComponentControl( TInt aIndex ) const 這兩個麻煩的東西。

這兩個東西的麻煩處,在於若這個 containers 裡有著不同 life-cycle 的 component controls,那 programmer 要決定何時回傳哪一個 component control。

不過,它的 sample code 對於 CleanupStack 的運用,就顯得很怪異。
The Problametic Edwin
Symbian OS C++ for Mobile Phones vol 3 (Google Book) 的說明也無法令我釋懷。或者我要寫一個 debug app 去測試一下那個 CleanupStack 和 ownership 的問題(除非可以讓我看到 Components().AppendLC() 的定義啦)

Online Bookshelf

最近做 research 時找到一個 blog,post 了很多書和雜誌,有興趣的可以去看看:Khmer W

還有一個 online 的 bookshelf: Safari Books Online,付一個月費就以日日閱讀不同的書,$78 一個月,抵唔抵就見仁見智。

真正的魔術師,其實是助手


真正表演緊魔術的,可能其實是助手。魔術師只是行行企企做手勢,落手落腳走來走去的,大部份都是助手。

太強了,Tetris的神人

Need for Speed: Shift

由於之前在朋友家玩過一次,所以在第一次啟動的測驗中跑出第一,可以買架 Audi S3 不用屈就於 Volkswagen Golf GTI。這是自己混出來的寶藍色。

玩了兩日,把贏了賽事的錢都用來升級這架 S3,結果,它越來越快。後來發現它在彎位前曉得自己剎制,原來是系統的 Brake Assist 設定為 Low。那即是說我只要發現車子慢下來,補多一腳踩 brake 就能過彎,似乎失去了賽車的趣味(難度),所以就把這個 brake assist 關了。結果,除了駕車感覺真實了,還會發生…

速度太高,就算踩了剎車都收制不及,應該要加埋拖波,不過遊戲裡很難感受拖波的效力。

嘩!炒到飛起咗。

打保齡咁樣碌咗出去。

請問,仲有冇人敢坐我既車呢?

Say bye-bye to Parallels

屋企的 iMac 終於換上了新的 OS - Snow Leopard (Mac OS X 10.6),Hard Disk 立即多了約 15GB 的空間,還不止如此,驚喜陸續有……

一裝完 Snow Leopard,開機的歡迎畫面之後就出現這個:
Incompatible software

Some of the software on your computer is incompatible with this version of Mac OS X. Because this software may cause problems with your computer, it has been moved. You can delete incompatible software that was moved.

Incompatible software on your computer was moved to a folder named "Incompatible Software" on your startup disk:

Parallels Desktop: version 2.5 of Parallels is not compatible with Snow Leopard.

For more information about incompatible software, see this Apple Support article: http://support.apple.com/kb/HT3258.

Snow Leopard 手起刀落幫我踢走乞人憎的 Parallels!如果真係唔可以再用 Parallels(之前用過 Parallels 已經死機幾次),那就連帶裝在 Parallels 裡的 OS 都要被踢走,隨時取回 20GB 以上的空間,應該有一兩個 XP、2000 Pro、Ubuntu 同埋 Windows 7?

又有新的 S60 Touch 機發佈

Nokia 最新發佈的 Touch 手機:
截至目前為止,Nokia 的 S60 Touch 機合共有以下:
  • Nokia 5800XM (3G)
  • Nokia 5800XM (2G)
  • Nokia N97
  • Nokia 5530XM
  • Nokia 5230
不過,從公司的 Projects 就可以感受到如今手機市場的慘況,不是因為要加班,反而是因為沒有加班。

Nokia 還發佈了一台 Netbook:Nokia Booklet 3G(Spec)。想趁 Apple 推 OSX 的 Netbook 之前攻佔市場吧?
