Explore Twisted, the Python-based event-driven networking engine,
and review several of its most popular application projects. It is
written by community leaders who have contributed to many of the
projects covered, and share their hard-won insights and experience.
Expert Twisted starts with an introduction to event-driven
programming, explaining it in the context of what makes Twisted
unique. It shows how Twisted's design emphasizes testability as a
solution to common challenges of reliability, debugging, and
start-to-finish causality that are inherent in event-driven
programming. It also explains asynchronous programming, and the
importance of functions, deferreds, and coroutines. It then uses
two popular applications, treq and klein, to demonstrate calling
and writing Web APIs with Twisted. The second part of the book
dives into Twisted projects, in each case explaining how the
project fits into the Twisted ecosystem and what it does, and
offers several examples to bring readers up to speed, with pointers
to additional resources for more depth. Examples include using
Twisted with Docker, as a WSGI container, for file sharing, and
more. What You'll Learn Integrate Twisted and asyncio using
adapters Automate software build, test, and release processes with
Buildbot Create clients and servers with Autobahn Transfer files
with Magic Wormhole Distribute cloud-based file storage with Tahoe
LAFS Understand HTTP/2 with Python and Twisted Support for
asynchronous tasks using Django Channels Who This Book Is For
Readers should have some Python experience and understand the
essentials of containers and protocols, but need not be familiar
with Twisted or the associated projects covered in the book.
The practical reference book and guide to fans, ventilation and
ancillary equipment with a comprehensive buyers' guide to worldwide
manufacturers and suppliers.
Bill Cory, well-known throughout the fans and ventilation industry,
has produced a comprehensive, practical reference with a broad
scope: types of fans, how and why they work, ductwork, performance
standards, testing, stressing, shafts and bearings.
With advances in technology, manufacturers have had to continually
improve the performance and efficiency of fans and ventilation
systems; as a result, improvements that once seemed impossible have
been achieved. Systems now range in all sizes, shapes, and weight,
to match the ever increasing applications.
An important reference in the wake of continuing harmonisation of
standards throughout the European Union and the progression of
National and International standards. The Handbook of Fans and
Ventilation is a welcome aid to both mechanical and electrical
engineers.
This book will help you to...
-Understand how and why fans work
-Choose the appropriate fan for the right job, helping to save time
and money
-Learn installation, operational and maintenance techniques to keep
your fans in perfect working order
-Discover special fans for your unique requirements
-Source the most appropriate equipment manufacturers for your
individual needs
* Helps you select, instal, operate and maintain the appropriate
fan for your appliaction, to help you save time and money
* Use as a reference tool, course-book, supplier guide or as a
fan/ventilation selection system
* Contains a guide to manufacturers and suppliers of ventilation
systems, organisedaccording to their different styles and basic
principles of operation

The entire nation is threatened. When dreaded earthquakes and rare
late-season storms attack both coasts of North America, lives
everywhere are in jeopardy. In the heart of the country, in a quiet
neighborhood in Colorado, people would die but for the efforts of
one man. And through it all, though their lives are in danger, the
neighbors work together, trying to salvage what they can from the
results of the storms, the evils of criminal attacks, and a justice
system that might destroy a war hero's family.
William Johnson published in 1858 a slender volume bound in green
cloth, (Smith, Elder & Co.) which was entitled "Ionica," and
which comprised forty-eight poems. In 1877 he printed privately a
little paper-covered book (Cambridge University Press), entitled
"Ionica II," containing twenty-five poems. This book is a rare
bibliographical curiosity. It has neither titlepage nor index; it
bears no author's name; and it is printed without punctuation, on a
theory of the author's, spaces being left, instead of stops, to
indicate pauses. In 1891 he published a book, "Ionica" (George
Allen), which contained most of the contents of the two previous
volumes, together with some pieces not previously
published-eighty-five poems in all. The present volume is a reprint
of the 1891 volume; but it has been thought well to include, in an
appendix, certain of the poems which appeared in one or other of
the first two issues, but were omitted from the 1891 issue,
together with a little Greek lyric, with its English equivalent,
from the "Letters and Journals."
