第 42 個梅森質數

Slashdot 報導第 42 個梅森質數可能被找到了,現在正在 double checking (依照往例,是用不同的 algorithm 去算):42nd Mersenne Prime Probably Discovered

MathWorld42nd Mersenne Prime (Probably) Discovered 有列出一張表,進幾年來的梅森質數都是由 GIMPS (the Great Internet Mersenne Prime Search) 所跑出來的。(類似 SETI@home 的作法,讓 user 參與)

TAOCP – The Art of Computer Programming

這是在鳥窩上看到的新聞:Volume 4 終於要出版了… 不過,是一部分 -_-

該死的賊老頭 Donald E. Knuth 終於要把一部份的 Volume 4 丟出來了:(quote from Exclusive Excerpt from Volume 4 of The Art of Computer Programming)

Finally, the answer to one of computer science’s most burning questions, “When is Volume 4 coming out?”

More than forty years in the making, the long-anticipated Volume 4 of The Art of Computer Programming is about to make its debut… in parts. Rather than waiting for the complete book, Dr. Knuth and Addison-Wesley have elected to publish it in installments (“fascicles”) à la Charles Dickens.

雖然大家都沒期待他能活著寫完七本 (別打我,這的確蠻多人都這樣想的啊 :p),不過許多人對於他又丟出了一些 (讓大家少了一些遺憾?) 還是蠻高興的 :P
