前言：My journey to Learn and better understand Linux began back in 1998. I had just installed my first Linux distribution
and had quickly become intrigued with the whole concept and philosophy behind Linux.
這是英文原版的很清晰，希望能幫助到對(duì)linux感興趣的朋友。

《笨辦法學(xué) Python》(Learn Python The Hard Way，簡(jiǎn)稱 LPTHW)是 Zed Shaw 編寫的一本
Python 入門書籍。適合對(duì)計(jì)算機(jī)了解不多，沒有學(xué)過編程，但對(duì)編程感興趣的朋友學(xué)習(xí)使用。這本書以
習(xí)題的方式引導(dǎo)讀者一步一步學(xué)習(xí)編程，從簡(jiǎn)單的打印一直講到完整項(xiàng)目的實(shí)現(xiàn)。也許讀完這本書并不
意味著你已經(jīng)學(xué)會(huì)了編程，但至少你會(huì)對(duì)編程語言以及編程這個(gè)行業(yè)有一個(gè)初步的了解。

This book provides technical information about all aspects of 3GPP LTE. The areas
covered range from basic concepts to research-grade material, including future
directions. The book captures the current state of 3GPP LTE technology and serves
as a source of comprehensive reference material on this subject. It has a total of
12 chapters authored by 50 experts from around the world. The targeted audi-
ence includes professionals who are designers or planners for 3GPP LTE systems,
researchers (faculty members and graduate students), and those who would like to
Learn about this field.

This introduction takes a visionary look at ideal cognitive radios (CRs) that inte-
grate advanced software-defined radios (SDR) with CR techniques to arrive at
radios that Learn to help their user using computer vision, high-performance
speech understanding, global positioning system (GPS) navigation, sophisticated
adaptive networking, adaptive physical layer radio waveforms, and a wide range
of machine Learning processes.

The next-generation wireless broadband technology is changing the way
we work, live, Learn, and communicate through effective use of state-
of-the-art mobile broadband technology. The packet-data-based revolu-
tion started around 2000 with the introduction of 1x Evolved Data Only
(1xEV-DO) and 1x Evolved Data Voice (1xEV-DV) in 3GPP2 and High
Speed Downlink Packet Access (HSDPA) in 3GPP. The wireless broad-
band fourth-generation technology (4G) is an evolution of the packet-
based 3G system and provides a comprehensive evolution of the
Universal Mobile Telecommunications System specifications so as to
remain competitive with other broadband systems such as 802.16e
(WiMAX)

Someone who wants to get to know the customs of a country frequently
receives the advice to Learn the language of that country. Why? Because the dif-
ferences that distinguish the people of one country from those of another are
reflected in the language. For example, the people of the islands of the Pacific
do not have a term for war in their language. Similarly, some native tribes in
the rain forests of the Amazon use up to 100 different terms for the color green.

A few years ago I stood before an audience at a customer’s facility
explaining the merits of micromachining technology. The small
conference room was packed, and all ears were attentive. Everyone was
eager to Learn about thismysteriousbuzzword, “MEMS.”Although many
in the audience were nodding in a sign of comprehension, the glazed
lookson their facesbetrayed them. Thisexperience isnot unique, but one
that isrepeated frequently in auditoriumsaround the world.

The Raspberry Pi has become a computing phenomenon. This single-board miniature
computer, first released in February 2012 by the Raspberry Pi Foundation, has grown into
a series of nearly a dozen models that have sold a total of more than 10 million units in
five years.
Inexpensive to buy and to run, Raspberry Pi computers are great for enthusiasts,
good for games, and fun for children. Raspberry Pi computers are also terrific in the
classroom, enabling you to put on each desk an easily-manageable computer on which
students can do everything from Learning Internet use and essential office software skills,
through grasping programming basics in an easy-to-Learn format, to performing full-on
programming in Python, Java, C, and other languages. Better yet, you can install all the
software needed for those activities automatically alongside the operating system.
