燈光不是污染

earth night map

電燈是廿十世紀的最偉大發明﹐它照亮著人類的文化。讓人類征服黑暗﹐不用再依靠日光﹐脫離日出而作﹐日入而息的原始生活。我們終於可以取回屬於我們時間主權﹐晚間不用給無盡的黑夜支配。燈光是人類文明誌標﹐也是一個城市繁榮的象徵。從太空中回看地球﹐看到陸地上一個一個的光點﹐見證著人類進化的歷史。人類擁有自己光源﹐社會才能夠更有效率地運作﹐人們可以繼續辛勤地工作﹐也可以外出娛樂玩耍﹐晚上不用再無所事事。現代的城市二十四小時全天候運作﹐把黑夜照量得象白天一樣。地球不是平的﹐與其他地方工作有時差﹐朝九晚五不再是必然的上班規律。再者讓大量社會資源在晚上丟空﹐也是一種浪費﹐不若物盡其用﹐把黑夜變為過去的名詞。把黑夜照亮成為白天﹐不單只方便人們生活﹐更改善可以城市的治安。美國紐約八十年代罪惡橫行﹐市長朱尼安尼上任決心要整頓市容﹐他的其中一項措施就是改善晚間照明。今天大蘋果是美國治安的典範﹐也是一座繁華美麗的不夜城。

可惜一些環保人士﹐不能與時並進﹐反行文明之道﹐宣揚光害污染的歪理。他們認為大城市的燈光污染黑夜﹐五光十色的燈火取代點點星空﹐光線更加會影響大自然的生態環境。他們要在大城市到看星空的訴求﹐就如暴發戶旅客要在鄉間小鎮找大商場購物一樣可笑。若想抬頭滿天星空的話﹐何必強求在城市中觀看﹐而影響千萬人的生活質素呢。大可以放假時外出旅行﹐到遠離人煙的國家公園露營。體驗一下躺在星空下的樂趣﹐細數夜空中畫破天際銀河裏的星星﹐向從外太空掉進大氣層的流星許願。在國家公園是有燈光管制﹐在那兒光線的確是一種污染﹐因為會破壞大自然的景色。在大城市的燈光並非污染﹐而是人類現代生活的必須品。反過來在城市中黑暗才是污染﹐污染了我們燈火通明不夜天的美麗。正如我們去歌劇院要肅靜﹐可是沒有人會去看足球賽﹐ 卻投訴球場內吶喊的球迷在製造嘈音吧。

誠然環保人士的說話也不是一無是處﹐他們對燈光浪費電力的指控倒是有根據。現今很多照明採用發光效率奇差的鎢絲燈泡﹐大部份電力轉化成熱能而非光能。採用光管式的慳電膽可以節省多達一半的用電量﹐若進一步改用最新科技的LED燈﹐更可以把用電量再大幅降低。照亮黑夜是需要的電力﹐大部份是從化石能源生產出來。眾所週知化石能源不是再生能源﹐地球上只有既定的存量﹐用光了就沒用。照明系統應該改用再生能源﹐如太陽能或水力發電等。在外國很多街燈裝有太陽能電池﹐白天把電力儲起來﹐晚上就用來發光照明﹐不用浪費供電網的電力。未來的科技發展會讓我們不用再依靠化石能源來照明﹐也許在太空中建造巨大的反光鏡﹐或用光纖把白晝地區的光線引導給黑夜地區使用。珍惜善用地球的資源十分重要﹐但解決能源問題的唯一方法是創造和發展﹐而不是龜縮回去黑暗的中古世紀。

Speaking in front of CEO

Today we have a very special Toastmaster meeting. We invited the company CEO, Bob, to give a speech in the club and have a recognition ceremony for the club members. The speech by Bob is about career development. It is not the boiler plate speech he gave in the staff update. It is more inline with a Toastmaster inspiring speech. He told us stories from his career, then use the stories to emphasis the importance of the lessons he had learned.

From a bad presentation experience he once had in front of the CEO in TI, he learned the chance of speaking in front of the executives is very valuable, so don’t bomb it. The executives only have a few minutes of attention span, so you have to cut to the point fast, raise their interest and then explain the details later if they let you continue. Don’t try to deliver too many points, most people can remember a few points anyways. It is important to drive a few key points into their mind, so he can still remember what you talk when they walk out from the door. Those few minutes of presentation is the only chance for many people to leave a good impression to the executives, and at the end of the day it is the impression that counts.

Then he told us a story about why he left TI. There was a merge between three divisions. He was leading the most profitable division but the top jobs goes to another leading a money losing division. He thought he is smarter, more hard working, with good track record, so he should get the job. The lessons here is even you are very capable, you still have to good forester relationship with people at work, especially the right people. The guy who got the job is the one who can influence the directors to talk to the decision makers. Another tips from Bob is try to imagine where you will be in 5 years, then project the image onto yourself. Once again, it’s the appearance that matters. Dress and act like the person you want to be, and when time comes people need to find replace for that position, they will think of you first.

The last story was about him scrubbing the toilet in his summer job. This lesson is about managing expectation. Don’t look down on small and tedious jobs, you may amaze people how well you exceed their expectation.

Since it is a toastmaster meeting, I can’t help from counter the ums, ahs and all other blunder Bob made in his speech. Later in the meeting, he was invited to take table topic and got evaluated! No hands in pocket, it is not a good speech gesture and sign of nerviness.

As usual, I am one of the daring few speak in front of the CEO. I asked him a question in the Q&A session when everyone seems to remain silence. I guess I broke the dead air. I asked him how he made the jump from being an engineer to a manager. I think this question fits well with theme of today. In the table topic session, again there are not many people willing to speak in front of Bob, except Chris and me. Speaking in front of the CEO and get him know your name may or may not matter, but at least it couldn’t do any harm. Of course, unless you totally screwed up your speech and make an idiot out of yourself.

Harddrive

At work, I and a group of friends share an external hard drive for downloaded movies, mp3, TV series, etc.  We take parts in downloading torrents off the web.  Some download TV series, some other download movies.  I take care of mp3 and movies sometimes.  Last night it was my turn taking the hard drive home, copy new stuffs off from the disk and update the disk with my latest download.  Most of time, I contribute to the disk more than using the disk.  There is just not enough time to watch all the downloads.  I have a very bad habit every time I take the drive home.  I like to sample the new downloads.  I would start the new TV series in the disk, trying to get a feeling in what’s on TV in HK these days.  Once I started the first episode, it is hard to stop.  I keep watch one episode after another.  I have to blame this on TVB’s script writers.  At the end of each episode, they always leave a cliff hanger to keep the audience watching.  The TVB series are mostly soap operas, plots are built from the usual few templates.  It is just a waste of time, yet I wasted my time watching them.  I guess I should refrain myself from my curiosity, don’t open the first episode next time I got the hard drive.

Bridge to Terabithia 尋找仙境之橋

Terabithia 千萬不要給這齣電影的預告片騙了﹐這齣電影不是「魔戒」﹐ 不是「哈利波特」﹐更加不是Narnia。「尋找仙境之橋」並不是魔幻冒險的故事﹐而是一齣講述兩個小孩子純真友誼﹐以及探討死亡與生命意義的感人故事。這齣電影改篇自Katherine Paterson的兒童小說。這本小說的評價很兩極化﹐在外國有些學校這書是英文科指定讀物﹐但在另一些保守地方的學校局﹐則把它與「哈利波特」同例為禁書。當然今次迪士尼製作的電影版﹐目標是家庭觀眾市場﹐己儘量淡化具爭議性的內容﹐取而代之是用先進電腦特技﹐讓小孩子幻想出來的仙境世界呈現觀眾眼前。

故事發生在美國鄉間的一個小鎮﹐男主角是個五年級生﹐家境清貧但甚有繪畫天份。他在學校只是個毫不起眼的學生﹐還時 常給校內的惡霸欺負。他的鄰居搬來了一個從市城來的女孩﹐並與他在在同一班上課。這個活潑開朗滿腦子鬼主意的女孩﹐改變了男孩的平淡生活。他們在學校一起聯手對付惡霸﹐放學後在房子後面的樹林遊戲﹐幻想創作出仙境王國Terabithia。小男孩小女孩自封為王帝與王后﹐破舊樹屋成為他們的城堡﹐領養回來的小狗是忠心的騎士﹐青蜓蜜蜂是他們王國的臣民。他們率領國民保衛仙境﹐扺抗黑暗惡魔派來的入侵者﹐化身成為怪獸的松鼠﹐冒充巨人的樹妖。在這片仙境樂土﹐這兩小無猜渡過了不少快樂驚險的下午。有一天音樂老師帶小男孩入城去參觀博物館﹐他想多親近暗戀的音樂老師﹐沒有叫小女孩一同前往。而在當天小女孩獨自前住仙境時﹐不慎跌入河中遇溺。小男孩為小女孩的死自責內咎﹐故事最精采感人的地方﹐就是講述小男孩如何從死亡的陰影中走出來﹐如何開竅為自己找到救贖﹐讓小女孩永遠活在仙境之中。

這電影前半部充滿趣怪童真﹐兩個小孩子幻想出來的仙境世界﹐把成年觀眾也帶回年少無知時﹐讓我們懷緬在小學時常發的白日夢。電影後半部的心情卻一百八十度逆轉﹐特別是突然而來小女孩的死亡﹐完全沒有給任何心理準備。戲中只是輕輕帶過事發經過﹐沒有駭人的死亡鏡頭特寫﹐卻給觀眾心理上極大的震憾﹐質問上天為什麼會容許這樣不幸的事情發生。小男孩從大人口中得知好朋友離世﹐一時間還接受不了現實。他在對死亡只是一知半解的情況下參加喪禮﹐還反問父親不信耶穌的小女孩會不會下地獄。他在學校與取笑小女孩的同學打架﹐給老師叫了出走廊訓話﹐結果老師也忍不住哭起來。死亡是一個十分沉重的課題﹐很多成年人也沒法好好面對﹐一個五年級的小學生如何面對呢﹖ 小男孩沒有選擇逃避忘記﹐他在小女孩遇溺的小溪上﹐為小女孩起了一條通往仙境的橋。這齣電影很適合每個有親友過世的人觀看﹐觀眾可以從小男孩身上得到不少啟發﹐學懂如何去面對死亡。我不是一個眼淺的人﹐但看這齣電影時﹐不禁也有一點兒眼濕濕。這是一齣可以觸動心靈的電影﹐絕對值得推介。

Demonoid.com

Demonoid.com is probably the best torrent download site out there in the internet.  It is very resouceful, it has lots of latest music, movies, TV eposides, books and especially audio books.  Unlike other open to all torrent sites, demonoid.com keep tracks of the download/upload ratio of the user.  It will enforce the sharing rule that you have to give back your bandwidth to the torrent community.  As a result, they limit the number of users to avoid infrastruture overloaded  Thereforethe site does not open to registration most of the time.  Unregistered users only allow to download the torrent files from the past few days.  Like the early days of gmail, new registration is allow only by invitation.  Although the website policy forbid selling of invitation code, but the code is selling $15 a piece on ebay, and they are sold fast.  Today, I am so lucky that I came across the rare occassion that demonoid.com opens for registration.  I seize this chance at once, create an account and start downloading.  It is like entering a gold mine of digital information.  Probably they will close the registration in a few hours once the quota is used up.  If you like downloading torrents, go there and register before it is too later.
