Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox. This book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby. 2013 marks the 20th anniversary of the Ruby language. We’re proud that throughout its history, we’ve continued to cover the latest version of Ruby. Would you like to go from first idea to working code much, much faster? Do you currently spend more time satisfying the compiler instead of your clients or end users? Are you frustrated with demanding languages that seem to get in your way, instead of getting the work done? Are you using Rails, and want to dig deeper into the underlying Ruby language? If so, then we’ve got a language and book for you! Ruby is a fully object-oriented language, much like the classic object-oriented language, Smalltalk. Like Smalltalk, it is dynamically typed (as opposed to Java or C++), but unlike Smalltalk, Ruby features the same conveniences found in modern scripting languages such as Perl and Python. The combination of the power of a pure object-oriented language with the convenience of a scripting language makes Ruby a favorite tool of intelligent, forward-thinking programmers. The Pickaxe contains four major sections: An acclaimed tutorial on using Ruby. The definitive reference to the language. Complete documentation of all built-in classes, modules, and methods. Complete descriptions of all 97 standard libraries. This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9, 1.9.2, 1.9.3, and 2.0). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, and the new block declaration syntax, am

新年自己设计的一款PCB直尺，开发环境为Altium Designer 18.1.9/Windows 7 64Bit。虽然淘宝上有很多卖PCB尺的，各人认为，除了NVIDIA版的PCB尺算得上是良心设计外，其他家的真是粗制滥造。看到NVIDIA的尺子有孔，自己也打孔、看到NVIDIA的尺子上有线，自己也画线，完全没有给使用者说明这些孔和线的作用是什么。所以呢，我决定自己设计一款，当然也参照了NVIDIA的设计,向大佬致敬，自己又加了些自己实验室的logo。 听说下载不了了？
