Samsung Galaxy S Captivate

My Palm Treo has reached the end of its lift, it is time to buy a new cell phone. I have been debating whether or not should I get the iPhone 4. iPhone 4 is sleek but I disapprove the control freak business tactics of Apple. Although almost everyone around me use a iPhone, I decide to go against the trend and embrace Android, a truly open platform compare to Apple’s walled garden. I naturally picked the Samsung Galaxy S, since it is the flagship Android phone and its specification is on par with iPhone 4. I used Rogers, so I have to picked up the AT&T version of Galaxy S Captivate. All Galaxy S versions are essentially the same under the hood, only cosmetic difference on the shell.

Galaxy S is actually slightly lighter and thinner than the iPhone 4. The Captivate looks like a Blackberry while the Vibrate looks like a iPhone. I must admit iPhone has better design of the shell, however that’s purely cosmetic. Galaxy S use normal SIM card, I just plug in my old SIM card it simply works. It comes with 16GB internal RAM and a micro SD card slot, so I can expand the memory if I ever need more, another point winning over iPhone. The screen and sound quality is top-notch, although the screen resolution is slightly less than iPhone 4. The battery is pretty good, I can watch 5 hours of video before runs out of the battery. In stand by mode with Wi-fi data enabled for background update and occasional short phone calls, it used about 20% in a day.

The contact and calendar links up to my gmail and facebook account. Since all the data is stored in Google’s server, I don’t have to worry about sync up with my computer and I can access my data anywhere. Transfer contact from my Palm is really easy, I just need to export the old address book to a vcf file and then import it to gmail, I got all the numbers and addresses into the phone in less than 30 seconds.

The haptic feedback of the screen is nice, every time I press a button or a key on the screen, the phone will vibrate to give me a freedback. The swype keyboard is definitely an improvement over iPhone. I don’t have to lift my finger when I type, I can simply trace the characters on the screen. I think with enough practice, I can type in swype as almost as good as using a real keyboard. The only complain is the stock OS does not come with Chinese input, I have to download the Chinese IME separately.

For most applications your found in iPhone, you can find the pretty much the same on Android. The Android apps market is the equivalent of the iTune app store. I can find most of the apps I need for free. I can also download paid software without paying from Applanet instead of download from the Google Market. iPhone boost to have many more apps than Android, but most of those extra apps belongs to the long tail that nobody really use. Android allows game console emulators, combined with the one stop game ROM download apps, I play virtually every single old games from the 80s and 90s on my phone.

iPhone has has a one stop sync up solution for music and video files with iTunes. Android does not come with any fancy sync up tools. Although Samsung has the Kies software but it is not very user friendly. For better or worse, a Android phone can just act like any other USB driver. I can easily copy files between my computer and my phone using Windows Explorer. I have a few options if I don’t want to plug in the USB cable all the time. I can either run FTP client from the phone to log into the FTP server on my computer or run FTP server on the phone and log in from my computer. The only problem is FTP cannot not handle Chinese character properly. Double Twist Air Sync comes close to a one stop solution, but its file database still has too much influence from iTune and does not let me control the directory structure. Web Sharing seems very promising, I can mount my phone as a network drive on my computer.

The stock Captivate comes with Android 2.1, so I decided to upgrade the OS to 2.2. Flashing the ROM of your cell phone is not for the fainted heart. I bricked my phone a few times before I get the new OS up and running. Instead of using the Samsung stock firmware, I used the Cognition ROM, which is better performance and has more features built into the OS. It double the speed of the stock ROM according to benchmark result. This is a major advantage of Android over iPhone, I can do whatever I want with the cell, including installing a complete new OS.

Android is not only a smart phone, but is really a full function computer inside your pocket. It just happen to be I can also make phone calls from this pocket computer. After all Android is Linux under the hood, with the root control I have complete control any feature of the phone.

PHIL333 Philosophy of Biology 生物哲學

因搬屋加工作繁忙﹐停學了差不多一年﹐上個學期重拾書包﹐再回山頂大學公餘兼讀哲學。可能是夏天學期學生少的關係﹐連帶課程的選擇也比較少﹐沒有我主修的道德或政治哲學的課﹐其他比較有興趣的課偏偏又排返工時間﹐只有這門生物哲學正好在午飯時間上課﹐於是在沒有其他選擇下便讀了這科。

其實學開前我也不太清楚這科的內容是什麼﹐因為這科沒有指定課本﹐教授每個星期給我們挑選哲學期刊的文章作教材。最大的好處是文章可以免費在大學的圖書館下載﹐不用花百多元買磚頭般厚的哲學課本。其次是課程緊貼學術界的最新發展﹐不用只學收錄在課本那些死去哲學家的名著﹐可以親身體驗現在最具爭議性的議題。在探討進化論本質的環節﹐教授更播放Youtube影片﹐累加式進化論和淘汰式進化論兩大陣營中﹐兩位最具代表性的哲學家的電視辯論。

課程分為六個部份﹐第一部份很短﹐簡單地重溫神創論的謬誤﹐先讀Paley那篇鐘錶匠論證的經典文章﹐然後再讀另一篇經典推翻盲目的鐘錶匠﹐內容與哲學入門教過的大同小異。上完前菜入正題﹐討論進化論在哲學上的意義﹐與及其衍生的相關問題。第二部份探討進化論在生物學外的應用﹐討論社會達爾文理論的影響。最常見對社會達爾文理論的批評﹐便是希特拉以此背書其優生學和族種主義﹐不過社會達爾文理論本身﹐只是把進化這個慨念應用在歷史和社會學的理論中。

第三部份講述有關進化論本身的不當謬誤﹐其中一個進化論的支持者常犯的毛病﹐高舉進化論萬能﹐以為什麼可以用進化論解釋﹐甚至無中生中作故事來自圓其說。可是有些生物的特徵﹐根本並非從進化而來﹐只是偶然地發展成現在的樣子﹐又或者只是另外一些特徵進化帶來的副產品。進化不一定是適者生存﹐生存可能只是因為運氣好。閱讀的文章中打個比喻說明這個問題﹐很多歐洲的中世紀教堂﹐擁有華麗巨型屋頂﹐屋頂下以要拱型作支撐。兩個拱型交換的地方﹐工匠和藝術家總愛把那兒裝飾得美侖美喚。可是如果說建築師特意建做拱型﹐好讓藝術家來擺放他們的作品﹐便是完全本末倒置了。只是因為要起巨型屋頂﹐必需面拱型支撐﹐那個多出來的空間﹐恰好被藝術家借了來用吧。

第四部份探討累加式進化論和淘汰式進化論的分別﹐基本上這涉形上學中因果關係的悖論。到底是進化讓某些生物擁有某些特徵﹐還是某些生物因為擁有某些特徵﹐才讓牠們在進化中沒有被淘汰呢。教授要我們就這個爭論交論文功課﹐我看完正反相方洋洋數萬字的期刊文章﹐得出的結論這是一個雞先還是蛋先的問題﹐雙方只是在咬文嚼字﹐朝不同方向解讀進化論。有些哲學問題看似很高深﹐不過同時間亦很無聊﹐大慨這個問題算是其一了。進化論是累加式還是淘汰式﹐不也還是同一個進化論。

第五部份探討何生學上的功用﹐如何決定一個器官的功用﹐如何分辨什麼是正常的功用。最大問題是功用在進化的意義上﹐與功用在人造設計的意義上﹐有著完全不同的定義。人造設計的功用﹐由設計者的意圖來決定。可是生物沒有設計者﹐生物只是進化出來﹐那生物器宮的功用﹐又是否等同其進化優勢呢﹖眾所周知心臟的功用是泵血﹐但心臟也同是發出啪啪聲的跳動聲音﹐那發出啪啪聲又是否心臟的功用呢﹖有哲學家用統計學去決定器官的功用是否正常﹐問題是如果有天出現超級眼睛病毒﹐讓世界上大部份的人者失明﹐那麼眼睛看得見到東西﹐還是否眼睛的正常功用呢﹖不要以為如何定義功用也只是咬文嚼字的遊戲﹐這個議題牽涉層面很廣泛﹐功用的定義是很多有關生物科技的道德爭議的核心關鍵。

課程的最後一部份﹐討論年頭才剛剛出版的一本新書What Darwin Got Wrong﹐這本書在生物哲學界引起一陣騷動﹐ 因為作者Jerry Fodor從哲學的角度﹐去試圖推翻進化論。作者認為進化論只是一個套套邏輯﹐並非有實質內容的科學理論。奈何這科沒有期終試﹐我亦選定了生物功用作為我的論文功課題目﹐最後幾節課並沒很有用心去上﹐這本書買回來翻了沒有幾多頁﹐所以我也不太清楚這本書的內容。或許有空我會拿出來閱讀﹐看看進化論如何被推翻。
