1870年3月19号,轮滑登上杂志《科学美国人》。它的制作人是伊利诺伊州奥尔尼的托马斯·呂德斯,被称作"佩德速度",后来,轮滑的轮变得小了很多,直径约为36厘米(15英寸)。吕德斯身材高大魁梧,他说自己用轮滑一直滑2个小时也不觉得累,同时他也说每一个人都可以滑轮滑,不论他们是什么体型。另一种轮滑出现在1923年,它的轮子在脚的内侧,而非外侧。(除了轮子的尺寸不一样以外,两种轮滑最主要的差别在于:由战车溜冰公司制作的轮滑,小轮在大轮的后面,增强整个轮滑的稳定性。)
从一开始,社交网络就被有效地隔离在互联网之外。比如,Facebook的海量内容通常不会显示在谷歌( Google )搜索结果之中。但是否非得是这种情形?比方说,Twitter搜索结果自动出现在一个标准的谷歌搜索显示页面,岂不是更方便?再比如,当你搜索Yelp时,为什么关于某家餐厅的最新Twitter消息没有显现出来呢?由于利益相悖,不同社交网络往往把各自的内容封锁在专利保护墙之内,但也有不少工具致力于创造性地弥合这道鸿沟。需要说明的是,本文作者的公司已经开发出了这样一种工具。

Gongloff piles on the bad news about 2014: GDP 'grew at a 1.8% annualized pace in the first quarter ... revising down its earlier estimate of 2.4% growth ... The first quarter's dismal growth was at least better than the 0.4% GDP growth of the fourth quarter of 2012. But it was still far from healthy, and economists don't see it getting much stronger any time soon.' And that's real bad news for the markets going into 2014.
