想像一下,說英語的自動...沒有思想。出來的話你的嘴很容易和快速。您了解即時。要做到這一點,你必須改變你的方式學習英語。您的第一個行動是停止學習英語單詞。什麼?停止學習英語單詞。沒錯,不背單詞。沒有母語的英語學習的記憶單詞。母語學習詞組。詞組群體的話,自然一起去。

Logical variables in Prolog

June 22, 2009 - 11:55pm
Submitted by Greg Buchholz on June 22, 2009 - 11:55pm.

I came across this code, which was supposed to demonstrate a Prolog program that couldn't be written in Mercury. I couldn't help but rewrite that as:

rank(Xs,Rs) :- pairs_keys_values(Decorated,Xs,Rs),
               keysort(Decorated,Sorted),
               numerate(Sorted,1).

numerate([],_).
numerate([_-N|Rest],N) :- N1 is N + 1, numerate(Rest,N1).

...This computes the rank order of a list of elements. For example rank([40,20,50,10],L). unifies L with [3,2,4,1], since 40 is the third largest element, etc.

solaris 10 x86 support for HME driver/card

June 15, 2009 - 11:08am
Submitted by mator on June 15, 2009 - 11:08am.

I've learnt that solaris 10 x86 doesn't have HME driver. This driver is used for example for older SUN made ethernet cards, and absence of driver for x86 makes them sparc-only hardware (on solaris 10 OS). Linux have driver for HME cards for ages (./linux-sources/drivers/net/sunhme.c comments dated back to 2000 year), both for x86 and sparc.

Currently we are in the F-11 bootstrap phase. Once that is done, expect to see some technical problems and probable solutions for new packages that we attempt to bootstrap on ARM.

Colors tend to be a part of our lives and in some cases they can influence how we react and feel. There is also historical evidence of color psychology being used by some of the early cultures. While there are some mainstream psychologists who tend to believe that color does not play a significant part in our behavioral patterns, color psychologists claim otherwise.

Partition a list numerically?

June 9, 2009 - 11:13pm
Submitted by Greg Buchholz on June 9, 2009 - 11:13pm.

Over on the Haskell Cafe mailing list, the topic of which of the following two definitions was better came up:

buildPartitions xs ns = zipWith take ns . init $ scanl (flip drop) xs ns


...or...
takeList :: [Int] -> [a] -> [[a]]
takeList [] _         =  []
takeList _ []         =  []
takeList (n : ns) xs  =  head : takeList ns tail
     where (head, tail) = splitAt n xs

...with various parties declaring the first example as "too smart", and others claiming that the second example is newbie level code. Well I'm much too lazy to try to reason out what those snippets might do at a glance. But the type signature was a pretty big hint as to what the intent was. So I fired up

Finding Another Free Software Compatible x86 Laptop: A*Note

May 25, 2009 - 4:05am
Submitted by Eus on May 25, 2009 - 4:05am.

After successfully finding an x86 laptop that is compatible with free software: ASUS EEE PC 1000HE (http://kerneltrap.org/node/17096), I got another order to find an x86 laptop that was bigger (preferably 14.1 inches laptop) and cheaper than ASUS EEE PC 1000HE. So, I went searching for one. After trying some tight-budget laptops that I dismissed because their wireless cards (e.g., Broadcom or newer Ralink cards) or graphics accelerators (e.g., new SiS chipset) were not compatible with free software, I landed on an A*Note 12.1 inches laptop whose vital devices were mostly free software compatible (fingerprint reader and built-in modem are nonvital for me).
