… and the Weight Companion Cube, isn’t.
(圖片來源: Greg’s Blog)
之前在跟 SKC 同學與 st 惋惜說 Companion Cube plush 賣完了,結果沒隔幾天 The Valve Store 竟然就重新上架了!立刻用 VISA 金融卡把東西訂下來(怕賣光),結果訂單卻因為 Billing Address & Shipping Address 不一樣國家被退訂… 立刻再訂一次,幸好有過。
(咦,我好像沒說過我在玩 Portal?)
(你覺得我會玩 FPS 很奇怪嗎?)
倒是原本做一半的 papercraft Companion Cube … 還是繼續用滿滿的愛做完(飄)。只是快用完了因為好難做orz

科幻作家 Arthur C. Clarke 昨日在斯里蘭卡過世,享年 90 歲。他寫了許多重要的科幻作品,還是首先提出同步衛星與太空電梯概念的科學家。
NASA 的 Statement 是對他的一生最好的描繪之一(節錄如下):
Although his personal odyssey here on Earth is now over, his vision lives on through his writing; he will be sorely missed.”
翻譯:
他個人在地球上的漂泊就此結束,但他的遠景會在紙上永存;我們將非常懷念他。
我對 Clarke 的書閱讀不多;有時間的話應該再看看幾本。
Update: Clarke 在 90 歲生日時錄給大家的談話。

How to dissect a paper by Ellen Gottlieb, 2003. Given to me from a teacher and it does help. A lot. Hope it helps you too.
Overview:
- Look at the title and authors.
- Read the abstract.
- Look at the figures to access quality (If they don’t look good, keep this in mind when assessing the paper)
- Read the last paragraph of the introduction which will give you the objective, the rationale and the approach
- Read the first paragraph of the discussion which will give you the objective, approach and major conclusion(s)
- Read the last paragraph of the discussion which will give you the implications and possibly future directions.
- Now read the paper through from being to end and critically analyze the paper.
- You might also want to look through the reference titles for additional info or other papers that might interest you.
When dissecting a paper, Ask yourself:
- What is the overall objective of this paper?
- What is the approach?
- What is the point of each figure or group of figures?
- What do the data actually prove? (Note: Figures which do not address objectives of the paper may be extraneous and could be eliminated or just mentioned in passing in a short presentation)
- Are the conclusions in the paper supported by the actual data or are alternate conclusions appropriate?
- What might you do next given their data?
Remember:
- Just because a paper is published, doesn’t mean it is correct
- A paper may have excellent data but incorrect (or skewed) conclusions. Base your future experiments on what the data show and not necessarily on the authors’ conclusions. This is often a good place to start on a new exciting experiments. Another good place for ideas on future experiments is the last paragraph of the paper.

Google Sky 出 Web 版了。中文版在這裡。Google Maps 的介面,沒有天球座標、黃道等等的按鈕可以切換。只有下面的按鈕是特別做的。
我覺得:
優點:不開任何程式直接查 SDSS 影像;三色合成影像很漂亮。
缺點:除了座標、黃道等可以再提供 RVB 不同頻段的照片;點某處之後顯示該星的編號之類的。這兩個做的出來或許可以取代那些從 SkyServer 拉 SDSS 影像的程式(含 Google Earth)?
Google 果然是立志於整理全天下資訊的公司呀,嘖嘖。
Update: 輸了,這篇貼上來隔天 Google Sky 就出現了 X-Ray / 紅外線太空望遠鏡的影線可以切換;還有透明度可以比較不同波段的強度… 真強。

有人在關心美國選舉嗎?
今天吃飯的時候不小心看到一則TVBS的傷眼美國總統大選報導。
兩分鐘的新聞剪接 CNN Politics 的畫面,講了半天除了「Obama 贏得懷俄明州」以外一點重點和分析都沒講到。只看那兩分鐘的新聞的話完全看不出來 Obama 在為什麼會贏、或是 Hillary 之前怎麼贏 Ohio primary 的… 這位記者的編譯功力有強到;也不過就是看看 CNN,翻成中文重說一遍也可以講成這樣。我都覺得我如果在這裡寫美國選舉新聞週報可能都寫的比他好。
這種報導竟然還是來自於自己號稱是唯一來自台灣立足國際的華語新聞台呢。這些媒體狹隘的視野帶給大家「國際觀」不是偏差、是空泛;真是令人擔心。還是努力學外語吧去聽國外 Podcast 吧,唉。

最近很倒楣,發生的一堆事情,連寫下來的力氣都沒有。所以就條列式吧(飄走)
- 花兩天的時間研究如何編碼 WretchLeech 的 JavaScript。本來考慮用 JScript.Encode 但是它似乎無法處理 UTF-8,所以最後還是只能用 YUI Compressor obfuscate。
- 被家人放鴿子。
- 硬碟磁區壞掉,被迫換回 Windows,失去兩天的生產力。(找的到 /etc/sdf 但是 /etc/sdf1 沒有出現不知道是什麼意思。幸好還可以用 Ext2IFS 從 Windows 讀…)。
- 存摺被補褶機印壞,印到別人的資料(那個人領每月3000的老人年金加約1500的三節獎金,可是都沒領)。
- 被買家趕著寄出去的網拍商品最後卻存局候領。
- 吃到很難吃的學校餐廳。
還好前幾天這段連鎖倒楣的日子結束了。可是寒流又來了…
