教你通行暗网,但暗网不是个好地方

暗网,隐网,深网,听着很吓人,是吧。在媒体的推波助澜下,这些东西的确变得神秘而又不可触碰起来。但是,说实话,有什么难的呢,难道每个暗网用户都是计算机高手不成? 什么是暗网? 这里有点区别,倒不如这么说吧,无法直接由搜索引擎搜索到的页面都属于隐网,也就是The Hidden Web。 媒体搞了一个冰山理论,什么绝大多数的网络都是罪犯的天堂,也是可笑之极, 那我知乎的个人编辑页面也成为犯罪天堂咯?这里所要澄清的是,隐网的确很多,但是我们即将要讨论的暗网却并非如此。 暗网, 数量在几万左右,不时关闭,不时开启,有违法色情,毒品与枪支的交易,当然还有FBI的钓鱼网站。这也是大家所熟知的。如果要深入了解下具体,可以看看这篇文章:出于好奇,我去暗网里瞧了瞧 —— 你就别去了 暗网网站的网址一般都如此:,而这是无法用普通的浏览器访问的,而是一个加密浏览器,也就是我们的Tor。 如何使用Tor...

H

After learning the Gas law, that I got some general idea of the beauty of equations, I think the expression of textbooks is pretty strange, they trying to divide one simple formula to several different unclear ones, hmm… I think the better the equation is the more factors it includes in; it does not let the question become complicated but even make it even simpler because people do not need...

Standard of Being My “Friend”

S

There is a man who has similar intelligence and wisdom as I do, I do not need to explain something over and over again, and again, he can understand me, he does understand me, which I can feel it. We have the same hobbies, senses, we get together every day when I got some misunderstanding of academic stuff, he knows what is the way to point it out for me, he could be annoying, but also quiet.

论幼年的思考方式

幼年这个时间上的节点,导致了其思考方式的特殊性,因为思考的广度有限,所以常常将毫无关系的两件事物关联在一起。
比如:我小的时候看过一本叫做“抽筋神探”的漫画,其主角的名字就是“一鸣”, 然后过了一段时间,学校旁开起了一家“一鸣真鲜奶吧”,我就不由自主的认为这两者之间有某种联系。
