國內規模最大的 BBS 站 (電子佈告欄系統) 台大 PTT (批踢踢實業坊) 於 22 日凌晨傳出系統異常。
PTT 是於 1995 年，由台大資工系學生創立，發展至今已成為全台灣最大的 BBS 站。同時上線人數可高達七萬人。主要使用族群為學生、上班族。即使在網際網路早已發展出各種多媒體互動式服務的今日，PTT 採用純文字操作界面的服務型式仍然受到廣大歡迎。
批踢踢實業坊，在 22 日凌晨一點半左右傳出有系統異常現象。根據網友 XDite 在其部落格發表的資料，當時登入的使用者都可獲得站長權限，亦即可以看到網友註冊時，所留下的個人資料，及匿名討論版上發文者的代號。部份看版內容甚至遭到大量刪改。還有使用者反映，可以任意派發站上通行的虛擬貨幣等等。
站方發現後緊急停機維修，目前已重新開放。但仍有使用者回報零星異常，站務人員並陸續處理復原中。
資安專家分析，該事件可能肇因於程式管理不當或系統漏洞。
消基會董事長程仁宏表示，由於 PTT 乃學生維運的非營利服務，使用者與站方的關係並非消費關係，因此使用者無從主張權利。不過程仁宏同時提醒，若是由商業組織提供的免費服務發生類似外洩事件 (例如 Yahoo 或 Google 的免費信箱)，消費者便有權要求賠償。他解釋，由於免費服務是營利機構用以吸引消費者的手段之一，且可能會以廣告等方式間接獲益，消費者仍可以對確實造成個人損失的服務提供者主張權利。

...Excess protein consumption can cause a variety of problems including bone mineral loss, kidney damage, and dehydration. Your body can only use so much protein, the excess is either broken down through oxidization, placing an enormous strain on the kidneys, or it is stored as body fat. Neither option is particularly desirable...

Since the vegetarian diet is the most effective solution to global warming, under Supreme Master Ching Hai's guidance, members of The Supreme Master Ching Hai International Association recently opened a chain of Loving Hut vegetarian restaurants around the world, in the United States, Japan, Indonesia, Au Lac and Formosa. These places provide affordable and high-quality vegetarian delicacies to the public, bringing a positive impact on the food and beverage industry...
Meat or vegetables? Independent online (SA)
A recent study has revealed that giving up meat could drastically reduce one's carbon footprint. A diet with meat is responsible for producing in a year (as many) greenhouse gases as driving a mid-sized car for 4,758 km, the Institute for Ecological Economy Research (IOeW) said last week. But the food a vegetarian consumes in (the same period of time) is responsible for generating (gases only) as driving for 2,427km, the IOeW said in a study commissioned by independent consumer protection group Foodwatch...

The term pleather ("plastic leather") is a slang term for synthetic leather made out of plastic, a portmanteau of plastic and leather, the term can be either descriptive, or derogatory, depending upon the user (the derogatory use implies use as a substitute for genuine animal hide leather to cut costs)...

- Galactic Highway - The Wormhole
- Stream of Time
Wormholes are a valid consequence of Einstein's general relativity view on the universe. A wormhole, in theory, acts as a shortcut or tunnel through space and time. There are several versions on the same theme (i.e. wormholes may link different universes; they may link the two separate locations in the same universe; they may even link black and white holes together), but the physics is similar, wormholes create a link two locations in space-time, bypassing normal three dimensional travel through space. Also, it is theorized, that matter can travel through some wormholes fuelling sci-fi stories like in the film Stargate or Star Trek: Deep Space Nine.
If wormholes do exist however, it is highly unlikely that you'll find a handy key to open the mouth of a wormhole in your back yard, they are likely to be very elusive and you'll probably need some specialist equipment to travel through them (although this will be virtually impossible).
Alexander Shatskiy, from the Lebedev Physical Institute in Moscow, has an idea how these wormholes may be observed. For a start, they can be distinguished from black holes, as wormhole mouths do not have an event horizon.
Secondly, if matter could possibly travel through wormholes, light certainly can, but the light emitted will have a characteristic angular intensity distribution. If we were viewing a wormhole's mouth, we would be witness to a circle, resembling a bubble, with intense light radiating from the inside "rim". Looking toward the center, we would notice the light sharply dim. At the center we would notice no light, but we would see right through the mouth of the wormhole and see stars (from our side of the universe) shining straight through.

Plato argued that time is constant - it's life that's the illusion. Galileo shrugged over the philosophy of time and figured out how to plot it on a graph so he could get on with the important physics.
Albert Einstein said that time is just another dimension, a fourth one to go along with the up-down, side-side, forward-back we move through every day. Our understanding of time, Einstein said, is based on its relationship to our environment.
Weirdly, the faster you travel, the slower time moves. (Is it truely weird? Not quite!!) The most radical interpretation of his theory: Past, present, and future are merely figments of our imagination, constructs built by our brains so that everything doesn't seem to happen at once.
