原创 Linux 列出 USB Plug 資訊

USB Plug資訊可以由`udevadm info [device name or path]`,但往往插入USB後跟本不知道產生週邊對應的資訊,可能知道在`/sys/bus/usb/devices/`,執行`ls -l`得到結果如下: ``` /sys/bus/usb/devices $ ls -la total 0 drwxr-xr-x 2 root root 0 May 17 13:17 . drwxr-xr-x 4 root root 0 May 17 13:17 .. lrwxrwxrwx 1

Expert Visual C++-CLI

C++/CLI is Microsofts latest extension to C++ that targets the heart of .NET 2.0, the common language runtime. Expert Visual C++/CLI is written by visual C++ MVP Marcus Heege, who examines the core of the C++/CLI language. He explains both how the language elements work and how Microsoft intends them to be used. Even if you're new to C++/CLI and are planning to migrate to it from another language, this book will ground you in the core language elements and give you the confidence to explore further and migrate effectively. It provides concise, yet in-depth coverage of all major C++/CLI features; short code examples succinctly illustrate syntax and concepts, and more elaborate examples show how C++/CLI should be used.

Mastering Linux Shell Scripting

Shell scripting is a quick method to prototype a complex application or a problem by automating tasks when working on Linux-based systems. Using both simple one-line commands and command sequences complex problems can be solved with ease, from text processing to backing up sysadmin tools. In this book, you’ll discover everything you need to know to master shell scripting and make informed choices about the elements you employ. Get to grips with the fundamentals of creating and running a script in normal mode, and in debug mode. Learn about various conditional statements' code snippets, and realize the power of repetition and loops in your shell script. Implement functions and edit files using the Stream Editor, script in Perl, program in Python – as well as complete coverage of other scripting languages to ensure you can choose the best tool for your project.

Mastering Algorithms With C

There are many books on data structures and algorithms, including some with useful libraries of C functions. Mastering Algorithms with C offers you a unique combination of theoretical background and working code. With robust solutions for everyday programming tasks, this book avoids the abstract style of most classic data structures and algorithms texts, but still provides all of the information you need to understand the purpose and use of common programming techniques. Implementations, as well as interesting, real-world examples of each data structure and algorithm, are included. Using both a programming style and a writing style that are exceptionally clean, Kyle Loudon shows you how to use such essential data structures as lists, stacks, queues, sets, trees, heaps, priority queues, and graphs. He explains how to use algorithms for sorting, searching, numerical analysis, data compression, data encryption, common graph problems, and computational geometry. And he describes the relative efficiency of all implementations. The compression and encryption chapters not only give you working code for reasonably efficient solutions, they offer explanations of concepts in an approachable manner for people who never have had the time or expertise to study them in depth. Anyone with a basic understanding of the C language can use this book. In order to provide maintainable and extendible code, an extra level of abstraction (such as pointers to functions) is used in examples where appropriate. Understanding that these techniques may be unfamiliar to some programmers, Loudon explains them clearly in the introductory chapters. Contents include: Pointers Recursion Analysis of algorithms Data structures (lists, stacks, queues, sets, hash tables, trees, heaps, priority queues, graphs) Sorting and searching Numerical methods Data compression Data encryption Graph algorithms Geometric algorithms

21st Century C

Throw out your old ideas of C, and relearn a programming language that’s substantially outgrown its origins. With 21st Century C, you’ll discover up-to-date techniques that are absent from every other C text available. C isn’t just the foundation of modern programming languages, it is a modern language, ideal for writing efficient, state-of-the-art applications. Learn to dump old habits that made sense on mainframes, and pick up the tools you need to use this evolved and aggressively simple language. No matter what programming language you currently champion, you’ll agree that C rocks. Set up a C programming environment with shell facilities, makefiles, text editors, debuggers, and memory checkers Use Autotools, C’s de facto cross-platform package manager Learn which older C concepts should be downplayed or deprecated Explore problematic C concepts that are too useful to throw out Solve C’s string-building problems with C-standard and POSIX-standard functions Use modern syntactic features for functions that take structured inputs Build high-level object-based libraries and programs Apply existing C libraries for doing advanced math, talking to Internet servers, and running databases

Android 3.0 Application Development Cookbook

The book is written in a cookbook style, presenting examples in the style of recipes, allowing you to go directly to your topic of interest, or follow topics throughout a chapter to gain in-depth knowledge. If you are new to Android application development and looking for a quick start, or if you are an experienced Android developer looking for a reference guide, then this book is for you. Ideally, you should know some Java and a little about mark-up languages but this is by no means necessary. This book will teach you how to write rich Android applications from scratch in no time.
