8.9 Earthquake struck Japan triggering a Tsunami
Mar 11, 2011, 13:46, A ferocious tsunami spawned by one of the largest earthquakes ever recorded slammed Japan’s eastern coast today, killing at least 60 people as it swept away boats, cars and homes while widespread fires burned out of control. Tsunami warnings blanketed the entire Pacific, as far away as South America, Canada, Alaska and the entire U.S. West Coast.
中国功夫,弱还是强?
网上已经有很多关于中国功夫和外国各种搏击术的对比。无外乎这样几种观点:
1)绝对力量–中国功夫处下风;
2)抗打击技巧–中国功夫缺乏实用性;
3)拳台实战–传统练家往往不敌练自由搏击的拳台常客。
但是,这种对比对中国武术公平么?
中国武术出身民间,基本面既不是如军队的正面作战,也不是如拿性命供人娱
乐的拳台搏击,甚至不是黑社会帮派斗殴的首选方式。
中国武术的基本面同样有三。第一是健身。第二是自保。第三偷袭。
所谓健身,就造就武术普通套路的普及性和简易性。例如简化太极拳,太祖长
拳,以及种种舞刀舞剑的套路。这些入门级别的套路,本来就不是为实战设计
的。当然按设计好的套路对打,可能具有一定的观赏性,但实战作用无限接近
于零。这些套路的目的在于,锻炼人体的柔韧性,平衡性,灵敏性,协调性,
以及耐久力。
如果坚持锻炼这些套路,虽然对你去击杀敌人未必有多大帮助。但是,如果你
遇到敌对行为,例如抢劫,或者卷入斗殴,你将有更大的机会逃离现场,躲避
伤害。
这个引出武术的第二个,也是更高一层次的基本面:自保。
基本的武术套路锻炼,让人的柔韧性,平衡性,灵敏性,协调性,以及耐久力
得到增强,无需借助现代化健身房的昂贵设备,同时不象健身房那样枯燥。同
时打下基本攻防动作的基础。这个在健身房是学不到的。在这个基础上,各种
武术流派都有进一步的对抗性训练。训练并不依循固有套路,而是讲解各种招
式的实战价值,包括敌人进攻时何种招式可以达到最大限度减轻打击的效果,
以及分析对手招式的破绽,以最佳方式回击。
这个的基础是运动战。就是在稳健下盘的基础上闪转腾挪。以我大学武术课学
的八极拳为例,就有两三步内低姿移动5-6米的招数。太极拳拳打卧牛之地,
不是不能走,而是故意不走。这个远远超出现代竞技搏击拳台的大小。而没有
这个闪转腾挪,中国武术的灵秀之处就基本被完全废掉了。你不能躲,那么只
有硬架硬抗,抗打击技巧的重要性才脱颖而出。学会了这些运动战的技巧,那
么你就可以利用地形,树木,建筑,人群,利用敏捷性让敌人打你不着。而你
则可以从容决定是耗还是跑。这个才是中国武术自保的精华所在。
比如那个一拳KO少林武僧的美国肌肉棒子。如果让他和那武僧在方圆百亩的森
林中游斗,跑跑不过,打打不着。体力20分钟耗光。剩下是不是任人宰割了?
有了这个运动战的基础,更上一步,偷袭。在将敌人运动疲惫之后,捡敌人的
破绽,利用爆发力打击薄弱部位。这个没有什么体育道德可言,挖眼,击耳,
掏裆,刺肋,飞镖,毒箭,都可以上。这样即使你的爆发力只有敌人的1/3,
仍旧可以制胜。但是虽然现代地下搏击不禁止打击薄弱部位,可是没有了游斗
制造的战机,为游斗训练出来的身体在绝对力量的短距爆发力以及抗打击技巧
和抗打击力方面的差距就被强化和放大。结果就是传统武术不敌现代搏击。
但是实战性呢?试问,如果你半夜遇匪,你是会和匪徒画一块5×5米的地方回
合对打,还是会尽量利用地形地物,不限时间和地理范围,游斗摆脱?答案
不言自明。
从社会价值而论。中国大量壮年老年人群以武术套路健身,延年益寿。你何时
看到谁用泰拳,柔道,跆拳道,拳击,散打健身?你看到的更多的报道是,
某某拳手伤痕累累,带着注定痛苦下半生的伤病退出拳台。某某前拳王50几岁
因伤病暴毙。
同时,你们大概也听过这个笑话。某日本警察,跆拳道黑带,内部竞技无往不
胜。某日,巡逻遇贼,奋力追赶,却因腿部肌肉过于发达,速度和耐力不足,
让瘦弱小贼逃脱。
综上所述,中国武术是一个从普及健身到实战制胜的庞大系统。而泰拳,跆
拳道,拳击,以及拳台散打,仅仅是用生命和健康博取看客一乐的,对长久健
康有害的极端运动方式而已。
中国武术的确面临绝境。不是因为其实战能力低下,而是因为其非嗜血性,
缺乏公众娱乐的卖点,以及复杂性,无法满足大众体育简约化的要求,以及
因此带来的不断失血和失传。
挽救中国武术,不在于挖掘它的拳台搏击价值。这是进一步打击它的方法。挽
救中国武术,只能从大众体育着手,在12年义务教育中,让武术健身从小深入
人心。
但是,恐怕这个永远难成现实了。
以此文向中国武术致悼词。
upgrade RHEL5 to RHEL6
By adding in “upgradeany” after the RHEL6 installation CD/DVD’s GRUB interface, it allowed to do the upgrading.
(Press TAB, and add on upgradeany after initre=initrd.img)
However, it failed on package kde-filesystem.
To resolve this, press Ctrl-Alt-F2, it will bring you into a shell of the installation environment.
From here, you can try
$ cd /mnt/source/Packages
$ yum -ivh –force –root /mnt/sysimage
This will tell you what’s wrong on installing it.
For mine, it was a series of folders in RHEL5 that should be replaced by symbolic links.
I hand moved the files in those folders to where they supposed to be for RHEL6, and created the symbolic links. Then the upgrading was able to proceed.
Cheers!
Install NVIDIA driver to RHEL6
$ setsebool -P allow_execstack on
$ nano /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
and put in
blacklist nouveau
options nouveau modeset=0
$ nano /boot/grub/grub.conf
and append

to the kernel line
$ nano /etc/inittab
change

$ shutdown -r now
After reboot:
$ sh NVIDIA-Linux-x86_64-xxx.xx.xx.run
It will install normally.

Recursive prime brother by Brillhart – Lehmer – Selfridge algorithm
Define:
p[k,i]=ABS[1+2*n[k,i]*p[k-1,1]*p[k-1,2]],n[k,1] is the integer with minimum ABS[n[k,1]] that makes p[k,1] a prime number, and n[k,2] is the integer with second minimum ABS[n[k,2]] that makes p[k,2] a prime number
The primality of p[k,i] can be proven using Brillhart – Lehmer – Selfridge algorithm recursively by using p[k-1,1] and p[k-1,2] as helper since n is a small integer, by reducing k to 1.
With this idea, taking
p[0,1]=1, p[0,2]=1
We got the n[i,j] ( columns : i; rows: k):
k | i=1 | i=2 |
1 | 1 | -2 |
2 | -1 | 1 |
3 | 1 | -2 |
4 | -3 | -5 |
5 | -11 | 19 |

Obama needs to lay off China
http://www.timesherald.com/articles/2010/11/22/opinion/doc4ceb43d395db0626282614.txt?viewmode=fullstory

Commentary
RALEIGH, N.C. — President Obama should lay off of China. The only thing keeping U.S. capitalism afloat is Chinese Communism.
During his recent Asian adventure, Obama discussed China with journalists in Seoul. He said that, “it’s very important that it (China) act in a responsible fashion internationally.” Obama added that the question of China’s currency “is an irritant not just to the United States, but is an irritant to a lot of China’s trading partners and those who are competing with China to sell goods around the world.”
To Chinese ears, this must sound like a temperance lecture delivered by a man wielding a pitcher of martinis.
Obama and other American officials accuse China of undervaluing its currency, thus making Chinese exports globally cost-competitive.
This fine whine is pretty darn rich, given Washington’s appropriately excoriated policy of “quantitative easing” (QE). This elegant phrase sugarcoats the massive printing of dollars by Federal Reserve chairman Ben “Kinko’s” Bernanke.
The Fed quantitatively eased $1.7 trillion after the economy slumped in 2008. Seeing how beautifully that worked, Bernanke embarked on a brand-new, $600 billion print run of dollars (nicknamed QE2), in exchange for U.S. Treasury bonds.
In the last two weeks since Bernanke announced this policy, the dollar skidded 1.4 percent against the British pound, 2.8 percent versus the Japanese yen, and 3.8 percent compared to the euro.
Thus, in an act of eye-popping hypocrisy, Washington practices precisely the same behavior for which it loudly denounces Beijing.
Besides, America should compete on quality, not price.
With China still in his crosshairs, Obama also said in Seoul, “Countries with large surpluses must shift away from unhealthy dependence on exports and take steps to boost domestic demand.”
He added: “No nation should assume that their path to prosperity is paved simply with exports to the United States.”
Now, do these godforsaken exports tumble from bombers piloted by the People’s Liberation Army Air Force? No. Do Chinese secret agents strap these products to donkeys and deploy them northward across America’s porous southern frontier? Negative. Nor do Chinese exports land on our beaches after being whisked here aboard Chinese Navy submarines.
Beijing’s exports should be no more surprising than a home delivery of wonton soup ordered from a local Chinese restaurant. Chinese-made goods are here because Americans demand them.
These “dirty Chinese exports” that protectionists like Obama condemn are ordered by U.S.-based managers and purchasing agents who market them to their American customers.
At the request of their U.S. clients and business partners, China is filling America’s homes and offices with increasingly high-quality goods at steadily falling prices.
And for this, Obama complains?
Obama should ask himself: “Why do US companies leave America to manufacture in China?” Perhaps lowering America’s 35 percent corporate tax (the developed world’s highest), easing Big Labor’s kung fu grip on U.S. factories, and making this country less sue-happy might entice domestic companies to build their goods in Sheboygan rather than Shenzhen.
Meanwhile, it is foolish to use the word “irritant” to refer to the country that pays America’s monthly allowance. China regularly purchases U.S. bonds, which helps keep interests rates low and lets Washington push its fiscal day of reckoning ever deeper into a receding horizon.
In fact, China bought $15.1 billion in Treasurys in September, boosting its portfolio of US government debt to $883.5 billion.
So long as China keeps bringing its checkbook to U.S. Treasury bond auctions, it is beyond idiotic for Obama and other US politicians to keep giving China the finger.
This is no way to treat America’s lead international banker.
Rather than scream like hungry infants about Chinese exports, Obama and like-minded American officials should stare in the mirror and ask themselves this: How has big government made the United States so uncompetitive that it is more economical for American companies to abandon domestic factories and, instead, manufacture in a nominally Communist country on the opposite side of the planet?

p(4) has database ID 96548 in The List of Largest Known Primes Home Page. The direct link is HERE.
These primes are recursively proven using OpenPFGW, by the command
pfgw -t (or tp) -h”p(n)” p(n+1)
The number
p(n+1)[m]=(2*m*p(n))^2+1
are reformatted by Mathematica to get the short expression.
The final certification code is
