Ruby on Rails continues to build up a tremendous head of steam. Fueled by significant benefits and an impressive portfolio of real-world applications already in production, Rails is destined to continue making significant inroads in coming years.
Each new Rails application showing up on the web adds yet more to the collective wisdom of the Rails development community. Yesterday's best practices yield to today's latest and greatest techniques, as the state of the art is continually refined in kitchens all across the Internet. Indeed, these are times of great progress. ...
Rails Core developer Jose Valim guides you through seven different tutorials, each of them using test-driven development to build a new Rails extension or application that solves common problems with these new APIs. You will understand how the Rails rendering stack works and customize it to read templates from the database while you learn how to mimic Active Record behavior, like validations, in any other object.

Ruby on Rails has shaken up the web development industry in a huge way—espe
cially when you consider that version 1.0 of Rails was only released in December
2005. The huge waves of enthusiasm for the new framework, originally in weblogs
and later in the more traditional media, are probably the reason why this book is
in your hands.
This book will lead you through the components that make up the Rails framework
by building a clone of the popular story-sharing web site digg.com. This will give
you a chance to get your feet wet building a simple, yet comprehensive web...
The last year or so has been an incredibly exciting time for web developers. New tools have
come out that make web development easier, more productive, and more fun. A slew of new
APIs are available that let you glue together data and services in interesting ways. As develop-
ers, we are more empowered with new and interesting technologies than ever before.
This book focuses on one API that has had a particularly profound impact: the
Google Maps API. Since you have this book in hand, you’re probably already convinced
of Google Maps’ importance....
In recent years, earthquake damage caused by the massive earthquake that happened in many
countries. For example, more than 250,000 people have been killed by the earthquake Haiti

The earthquake and Japan Tohoku coast was devastated by a large tidal wave
You don't have to know everything about a car to drive one, and you don't need to know everything about Ruby to start programming with it. Written for both experienced and new programmers alike, Learning Ruby is a just-get-in-and-drive book -- a hands-on tutorial that offers lots of Ruby programs and lets you know how and why they work, just enough to get you rolling down the road.
Interest in Ruby stems from the popularity of Rails, the web development framework that's attracting new devotees and refugees from Java and PHP. But there are plenty of other uses for this versatile...
This was the formula behind America’s information-technology boom in the last half of
the twentieth century. Not only did the country produce many more startups per capita
than Europe or Japan did, it consistently produced startups that grew to flagship status:
the now-defunct Digital Equipment Corp. in the 1950s, Intel and AMD in the 1960s,
Microsoft, Apple and Oracle in the ’70s, Cisco Systems and Dell in the ’80s, and
Amazon and Google in the ’90s, for example.
Crisis-driven layoffs are on the rise in many OECD countries and experience from previous
recessions shows that many skilled workers will become unemployed (see the example of Korea in
Box 1). High-tech industries (like IT, aeronautics or pharmaceuticals) and knowledge-intensive
services (like financial services) are announcing layoffs almost daily. This human capital will quickly
depreciate if the downturn is protracted.
To help with this work, we have held discussions with DfT, Network Rail, ROSCOs, manufacturers,
and the Railway Industry Association (RIA) but this document has been prepared as ATOC’s own
viewpoint on the issues rather than attempting to draw a full industry consensus.
We intend to go forward through the development of a wider Rolling Stock Strategy, that we
originally proposed, and which received support from Government in the recent Command Paper.
With successful presentations in Tokyo behind me, I boarded the 5:03pm Super
Express bound for Osaka complete with my ekiben (a special kind of Japanese
lunch box or bento sold at train stations) and a can of Asahi beer in hand. The
quintessential "Japan experience" for me is zipping through the Japanese
countryside aboard cutting-edge rail technology while sampling traditional
Japanese delicacies with my chopsticks, sipping Japanese beer, and catching
glimpses of temples, shrines, and even Mount Fuji out the spacious side window.

‘Eco-procurement’ is already a key concept for operators, manufacturers and policy-
makers, not least because railway rolling stock is often used for 30 years or more.
Adherence to strict environmental performance speciﬁ cations, including energy efﬁ ciency,
noise, diesel-exhaust emissions and recycling, must be considered when rail suppliers
But we need a sustained effort, which is why the President set an ambitious goal that by 2015 we
would have 1 million electric vehicles on the road, becoming the world’s leader in advance vehicle
technologies. To help reach this goal, the President is proposing bold steps to improve the
efficiency of all modes of transportation, from air to highways to rail to water, and to develop
alternative fuels. He is continuing to push forward on fuel economy standards for cars and trucks.
He has proposed to speed the adoption of electric vehicles with new more...
Today’s ‘renaissance’ of the railways has only been possible thanks to a multitude of
powerful research initiatives aimed at making fundamental improvements in the system
as a whole. Now, keeping rail at the forefront as the most environmentally friendly major
transport mode requires an even more rapid adoption of new technologies for clean and
efﬁ cient energy.
The world is on the threshold of a new era of
innovation and change with the rise of the
Industrial Internet. It is taking place through
the convergence of the global industrial
system with the power of advanced
computing, analytics, low-cost sensing
and new levels of connectivity permitted
by the Internet. The deeper meshing of the
digital world with the world of machines
holds the potential to bring about profound
transformation to global industry, and in
turn to many aspects of daily life, including
the way many of us do our jobs.
The new state-of-the-art class 423 metro train set is the latest result of advanced
European rail research, producing 56% less CO2 than the 35-year-old vehicle it
Procured by Deutsche Bahn, the new train is a lightweight compared to its predecessor,
weighing only 105 tonnes instead of 140.
Reduced dead weight saves some 25% of speciﬁ c energy consumption, while
regenerative braking accounts for further savings of up to 31%.
Note, however, the number of units under construction and proposed
in Denver County. This reflects the central city’s growing
population, especially as an urban lifestyle becomes more appealing
to younger tenants and to “lifestyle” renters. This is quite a turnabout
from recent history when suburban construction trumped urban development. In Denver this trend is
seen in downtown and along some of the RTD rail transit corridors. Transit-oriented development has certainly
come of age in Denver and is likely to accelerate with the completion of several new lines.
