ubuntu經常無聲

這是老問題, 目前還沒找到好解法, 列出一些線索

* /etc/init.d/pulseaudio stop 之後pulseaudio server仍然還在 根本沒有消失
* 可以強制用kill -9 殺掉pulseaudio
* 我用下列指令搞定
>asoundconf list
Names of available sound cards:
Intel
SAA7134
> asoundconf reset-default-card Intel
> asoundconf set-default-card Intel

* 接下來, 查看 /home/timwu/.asoundrc.asoundconf 應該要有內容
* 沒有pulse, 直接對Intel輸出仍可達到multiple audio stream 混音,
* 啟動pulse可以用asoundconf set-pulse

Bruce Lee - Wikipedia, the free encyclopedia

Physical fitness and nutrition

Bruce Lee in Way of the Dragon in 1972

Lee felt that many martial artists of his day did not spend enough time on physical conditioning. Bruce included all elements of total fitness—muscular strength, muscular endurance, cardiovascular endurance, and flexibility. He tried traditional bodybuilding techniques to build bulky muscles or mass. However, Lee was careful to admonish that mental and spiritual preparation was fundamental to the success of physical training in martial arts skills. In his book The Tao of Jeet Kune Do, he wrote

Training is one of the most neglected phases of athletics. Too much time is given to the development of skill and too little to the development of the individual for participation." "JKD, ultimately is not a matter of petty techniques but of highly developed spirituality and physique.^[44]

The weight training program that Lee used during a stay in Hong Kong in 1965 at only 24 years old placed heavy emphasis on his arms. At that time he could perform bicep curls at a weight of 70 to 80lbs for three sets of eight repetitions, along with other forms of exercises, such as squats, push-ups, reverse curls, concentration curls, French presses, and both wrist curls and reverse wrist curls.^[45] The repetitions he performed were 6 to 12 reps (at the time). While this method of training targeted his fast and slow twitch muscles, it later resulted in weight gain or muscle mass, placing Bruce a little over 160 lbs. Lee was documented as having well over 2,500 books in his own personal library, and eventually concluded that "A stronger muscle, is a bigger muscle", a conclusion he later disputed. Bruce forever experimented with his training routines to maximize his physical abilities, and push the human body to its limits. He employed many different routines and exercises including skipping rope, which served his training and bodybuilding purposes effectively.^[46]

Lee believed that the abdominal muscles were one of the most important muscle groups for a martial artist, since virtually every movement requires some degree of abdominal work. Perhaps more importantly, the "abs" are like a shell, protecting the ribs and vital organs.

He trained from 7 a.m. to 9 a.m., including stomach, flexibility, and running, and from 11 a.m. to 12 p.m. he would weight train and cycle. A typical exercise for Lee would be to run a distance of two to six miles in 15 to 45 minutes, in which he would vary speed in 3–5 minute intervals. Lee would ride the equivalent of 10 miles in 45 minutes on a stationary bike.^[47]

Lee would sometimes exercise with the jump rope and put in 800 jumps after cycling. Lee would also do exercises to toughen the skin on his fists, including thrusting his hands into buckets of harsh rocks and gravel. He would do over 500 repetitions of this on a given day.^[48]
