把box.net变成你的本地磁盘
大家都知道，box.net是一个很不错网络磁盘，在所有我使用过的网络磁盘中，它是令我最满意的一款。现在，我找到了另外一个使用box.net的方法，它可以让你像使用本地磁盘一样使用box.net，非常简单方便。
方法如下（windows XP环境下)：
1、进入网上邻居，单击左边栏中的”添加一个网络邻居”
2、在”添加网上邻居向导”中选择”选择另一个网络位置”
3、在输入框中输入”https://www.box.net/dav”。
4、在弹出的对话框中输入box.net的用户名和密码。
.....
5、自定义一个名称
6、进入网上邻居，就可以看到刚才设置的网络磁盘文件夹了。
7、双击进入文件夹，就可以自由上传和下载文件。
8、完毕。 :)
附：如果你使用的是MAC平台，你可按照How to use Box.net just like Apple’s iDisk来进行配置。另外如果你还没有box.net的帐户，请点击这里申请。

笔记本系统崩溃，郁闷中——
今天研究了一下注册表，胡乱山了一大堆东西，结果，system文件损坏，进不了系统了！ ：（
上网查了一下，知道了方法，却郁闷的发现我用不了，其中情况太过复杂，恕我不一一道来！
现在正在研究dos,不写了，继续.....

为什么用Google Blogger
自从Google Blogger新版上线以来，孙某一口气创建了N个，并天天窝在上面，乐不思蜀。而在此之前，本人仅限于看看他人博客，却从来不曾想过自己也参与其中。那么多提供Blog服务的网站，我为何却偏偏选择了Google Blogger，这与个人的价值及审美取向有莫大的关系。
QQ空间：花里胡哨的界面，看的我眼花。而且在高分辨率下的网页显示效果实在让人无法接受。加上一直不太欣赏腾讯的一贯作风，弄个QQ空间也是想尽办法掏我等穷人的钱袋，平时也是因为应酬才看看，所以根本不列入考虑的范围。
百度空间：孙某人对百度所知不多，百度的服务也极少用到，对百度的影响力了解也很有限，但是网络上有关百度的负面新闻不少。孙某人我实在不希望自己辛辛苦苦撰写的文章，最后因为某句话得罪某大牌公司或某位达人而惨遭封杀。.....
新浪博客：新浪一直以精英博客作为发展的主方向，鄙人乃一介草民，恐怕不入法眼。
MSN空间：鼎鼎大名的微软提供的免费服务，傻瓜式的操作，可惜的是老盖把网民也当傻瓜来看。特效代码是不让用的，非得用他的；用IE浏览才能保证显示正常；访问的速度那是和蜗牛有的比，也不用考虑了。
其他的博客：或是英文的；或访问上慢的不行；或不知道哪天就关门打烊了。
选来选去，最后当然还是投靠Google Blogger了，有安全感和信任感嘛，访问的速度也还不错。至于其他人怎么想，孙某人是不清楚的。

Could you jump off a bridge or a tall building and survive the fall?
Dear Cecil:
I've often read that if you jump off the Golden Gate Bridge, you will accelerate to the point where hitting the water will be like hitting concrete. But my little brain keeps saying, "Yeah, but it's WATER!" Could you jump off a bridge like the Golden Gate and contort your body in such a way that you'd survive? --Paul, Ann Arbor
Dear Cecil:
I've heard that if you jump off a tall enough building, you'll pass out before you hit the ground due to falling so fast. My friend tells me this is not true. He argues that skydivers free-fall and hit terminal velocity and are just fine. I told him that they haven't fallen long enough. Can you help me prove him wrong? --Katie, Bellingham, Washington
Cecil replies:
Of course not, numbskull. Your friend is right. Skydivers in free fall routinely reach terminal velocity, i.e., the speed at which air resistance and weight balance out and acceleration stops, which often exceeds 120 mph. During a typical plunge they may drop 10,000 feet in 60 seconds, remaining conscious throughout. (The free-fall speed record, incidentally, is 614 mph, set in 1960 by Joseph Kittinger, who stepped out of a balloon gondola into the exceedingly thin air at 103,000 feet.) Nonetheless the belief persists that anyone leaping or falling from a great height blacks out, has the breath sucked out of them, etc. Fact is, some pass out, but not all. We know this because--you knew we'd get around to your question eventually, Paul--people have in fact survived a leap off the Golden Gate Bridge, and staying alert is one reason they did.
Scientists have long been fascinated by what happens to people who fall from great heights without a parachute. Unsurprisingly, most of them get killed; perhaps surprisingly, a few don't. A prime example of the latter was a 17-year-old male who in 1979 leaped off the Golden Gate Bridge from a height of 250 feet. According to one report, "he recount[ed] a slowing of time initially, and mid-fall, when fully realizing the oncoming impact, strove to adjust his attitude to the vertical feet-first position. An almost perfect entry was achieved. Although dazed, he swam to shore" and checked into a hospital, where his worst injury turned out to be several cracked vertebrae.
Walking away from something like that is rare. The Golden Gate Bridge is said to be the most popular suicide location in the world--at least 1,200 people had jumped as of 2003, of whom fewer than 20 survived. A more typical outcome was that of a stuntman calling himself Kid Courage, who jumped off the bridge in 1980 trying to set a free-fall record. He landed flat on his back and was dead when pulled from the water with massive internal injuries.
The key to survival appears to be vertical entry. Your little brain is right, Paul--there's a difference between landing on water and landing on concrete, namely you can't dive into concrete. The 17-year-old male survivor said he may have touched bottom, perhaps 20 to 25 feet down--plenty of room to disperse the force of impact. In contrast, Kid Courage's body never sank beneath the surface, meaning he'd gone from 75 mph (a Golden Gate leaper's peak speed) to zero in maybe six inches.
Beyond a certain point even Olympic form won't save you. One expert claims the upper limit for surviving water entry is around 80 mph. Presumably it's less if you're hitting something solid. Still, the literature teems with spectacular exceptions:
In a 1942 paper, physiologist Hugh De Haven told of eight people who survived falls of 50 to 150 feet on dry land, many with only minor injuries. The common denominator: something to break the fall or soften the impact, such as loose dirt, the hood of a car, or, in one astonishing but verified case, an iron bar, metal screens, a skylight, and a metal-lath ceiling.
In 1963, U.S. Marine pilot Cliff Judkins's chute didn't open after he bailed out of his crippled fighter. He fell 15,000 feet into the Pacific, suffered numerous broken bones and a collapsed lung, but lived.
U.S. Army air force sergeant Alan Magee fell 20,000 feet from an exploding B-17 in 1943 and crashed through the skylight of a French train station. (A lesson emerges: Aim for the skylight.) Though his arm was shattered, he lived too.
When his bomber was shot down in 1942, Soviet lieutenant I.M. Chisov fell 22,000 feet into a snowy ravine. He was badly injured but recovered.
Luckiest of all was RAF flight sergeant Nicholas Alkemade, who leaped from his burning bomber in 1944 without a parachute at 18,000 feet. After a 90-second plunge, he crashed through tree branches in a pine forest and landed in 18 inches of snow. His only injuries: scratches, bruises, burns, and, in some accounts, a twisted knee.
