当年错失参与比特币的大好时机，时也命也！
往者不可谏，来者犹可追。
按照X网几位比特币和区块链技术的布道者，steemit.com有望成为新的一轮革命。
作为一枚懒散的宅男，是拒绝接受新事物的（其实本质是懒）
但是眼见着铺天盖地的讨论，各种前景展望，内心无法保持波澜不惊了。
对赚钱的期望有，但不是那么强烈，或者至少觉得不会那么简单的发帖就能赚钱（五毛党的职业，哈哈）
无论在哪里，一分耕耘一分收获，总是真理。当然，也有可能是耕耘了，没有收获。
更多的是有着极大的好奇
比特币、区块链、steemit.com到底魅力何在？
它们如何让无数的个人和公司痴迷其中？
他们运作的原理是什么？
这些技术除了挖矿（发帖）赚钱，还有哪些广阔前景？
等等等等
而单单的阅读一些布道贴，找一些科普文，貌似无法真正的解决我以上困惑。
“纸上得来终觉浅，绝知此事要躬行。”
那么就拿这个steemit.com来学习实践一下吧。
正好懒骨头也该动动了。
注册
大概4-5天前注册了steemit.com
https://steemit.com/@oflyhigh第一帖
注册完事，感觉一头雾水，发了个帖子，咋玩。点赞两人，收入0
https://steemit.com/howto/@oflyhigh/btgpq赚钱啦
因为偏头痛的缘故，找了本十多年前的入门书籍来读，写了个简单的读后感
像发博客一样发到steemit.com。21人点赞，收入，$40
（注：感谢猪网的各位大神，估计都是猪网大神给点的）
https://steemit.com/cn/@oflyhigh/unix-unbounded-a-beginning-approach谁动了我的Money？
刷新上边的文章链接，发现点赞的人没少
但是底下的金额变少了。
谁动了我的Money？或者有人点赞后取消了，扣钱了？
进钱包一看，原来是其中一部分金额发到钱包里了。
还是傻傻的搞不清楚，钱包里各个项目的区别和关系。扬帆起航，新起点
7/29/2016
撰写此文，作为一个开端。
以后会在本帖内更新学习实践的进程。
给自己一点压力和一点动力。
也希望能给别人一丁点参考。
让我们一起扬帆起航吧！steemit.com 我来了！

温故而知新！ 重读《UNIX Unbounded: A Beginning Approach》有感。
十几年前，因为工作的缘故接触Linux系统。
作为Windows盗版系统的“受益者”，除了学校《操作系统》课程接触的ls、cd、dir、pwd等几个有限的命令，实在是想不起再多的内容了。IBM社区上有一些很经典的Linux系统教程，不得不说从中受益匪浅。然而，工作需要，系统的了解和学习依旧迫在眉睫。这个时候我发现这本书《UNIX Unbounded: A Beginning Approach》，中文翻译为《UNIX初级教程》。
对于常年工作于Unix、Linux系统环境下的大牛，这本教程虽仍不失参考意义但略显粗浅。但对于当时的小白，简直就是及时雨。这本书从UNIX系统的发展讲起，介绍了简单的命令、VI编辑器、文件系统操作、Shell操作、UNIX通信、程序开发、Shell编程等等初学者迫切需要学习和了解的内容。
当然，一本初级教程不会让你瞬间变身Linux高手，但是无疑会让你在步入Linux辉煌殿堂的途中，少走无数的弯路，至少于我而言如此。
十几年前读完此书后，继续学习《UNIX环境高级编程》、《UNIX网络编程》等等经典教程，这本初学者的入门教程一直尘封至今。十多年后，虽然依旧偶然在Linux系统下工作，但无外乎周期性的执行几个命令和脚本，甚至于打开脚本之后，自己都忘记了每行代码的意义。PAD、智能手机等设备的兴起，让我们越来越远离纸质的书籍。更何况十几年小白入门的技术书呢？
幸或不幸，前几天偏头痛发作，无法长久面对刺目的电子屏幕。拿了几本文学书籍来看，发现无法沉静下来。拿了一些当年工作中学习的书籍来看，又觉得实在是深奥，感慨于当年如何一本本的啃读过来。于是在书架的角落里发现这本布满灰尘的《UNIX Unbounded: A Beginning Approach》，重拾起来，那段学习的、拼搏的美好时光仿佛又回到眼前。一行行代码、一个个命令，重现当时一段段难忘的记忆，或因难题困扰纠结，或因攻克难关欢喜欲狂。
重读《UNIX Unbounded: A Beginning Approach》，带来的不单单是美好的回忆，也重拾起这些年忘掉的知识点，又对十几年来学过的相关内容做了一遍系统的梳理，可以说收获满满。难怪古人说：温故而知新，可以为师矣。
不知道是否是这本书的功劳，读罢此书后，偏头痛已然康复。这算是另外一个收获吧。
撰文一篇，纪念一下十几年前的快乐时光，记录下来重读这本书的这点感慨，也推荐想入门Linux的朋友可以拿这本书来参考一下哦。
