|This book a no nonsense approach to learning the key points of Objective-C and iOS at the speed of light. It is a fast paced sprint through tons of hands on examples.
The books starts off with a nice introduction to Xcode by building a small twitter application using the new iOS 6 Social framework. The twitter application is used as the example in the first 3 chapters and then the rest of the book builds a recipe application.
I have listed the chapters below to give you an idea of the topics covered throughout the book.
Tweetings, and Welcome to iOS 6
Programming for iOS
Asynchronicity and Concurrency
Storyboards and Container Controllers
Documents and iCloud
Drawing and Animating
Testing and Fixing Apps
The App Store and Beyond
Wait! I Forgot (Or Never Learned) C!
To me this is not a reference book, but rather a great cover to cover read. There are a lot of books that I don't get far with that are hands on building of an application from start to finish, but this one really kept my interest. The applications being built are at the perfect level of complexity to introduce a ton of topics, but do not bog you down with a bunch of domain knowledge. I hate the books like this that spend 50% of the book explaining the non-technical what and why of what you're building.
I found the chapter on storyboards very cool. The authors take the recipe application built using a pre-iOS mindset using nibs up to this point in the book, and converts it to a storyboard application. They reuse all the view controllers built so far. This is a great chapter for showing the power of the MVC pattern used throughout iOS development.
The chapter on Documents and iCloud does a great job of introducing persistence by implementing the NSCoding protocol. There is no Core Data coverage in this chapter or the rest of the book. I also could not get the iCloud samples from this chapter to run, but I did not spend much time on trying to get it to work.
The chapter on testing provides a nice introduction to unit testing, debugging, and performance testing using Instruments.
I think a reader should have some experience with C or Objective-C before reading this book. Like I said above the authors have a very no-nonsense approach. But I would recommend a little more experience than what the author's put into the Wait! I Forgot (Or Never Learned) C! appendix. C in 7 pages is a bit to no-nonsense!
Over all I found the book a really enjoyable read. I definitely recommend it to anyone that wants to learn iOS through a hands on experience. This book will give you a great foundation to start building on.

Cloud computing is changing the way we look at IT costs, according to industry experts on a recent Cloud Luminary Fireside Chat panel discussion. Enterprise IT, traditionally viewed as a cost center, now plays a central role in the delivery of software-driven goods and services. Therefore, companies need to understand their cloud utilization and resulting costs in order to ensure profitability on their business offerings. Led by Bernard Golden, this fireside chat offers valuable insights on ho...

It's 2:15pm on a Friday, and I'm sitting in the keynote hall at PyCon 2013 fidgeting through a succession of lightning talks that have very little relevance to my life. Topics like "Python code coverage techniques" (ho-hum) and "Controlling Christmas lights with Python” (yawn - I wonder if there's anything new on Hacker News)...when Solomon Hykes takes the stage, unveils Docker, and the world shifts. If you haven't seen it yet, you should watch the video of Solomon's Pycon The Future of Linux C...

You hear the terms “subscription economy” and “subscription commerce” all the time. And with good reason. Subscription-based monetization is transforming business as we know it. But what about usage? Where’s the “consumption economy”? Turns out, it’s all around us. When most people think of usage-based billing, the example that probably comes to mind first is metered public utilities — water, gas and electric. Phone services, especially mobile, might come next. Then maybe taxis. And that’s ab...

This month I want to revisit supporting infrastructure and datacenter environments. I have touched (some would say rant) upon this topic since my post in April 2014 called "Take a Holistic View of Support". My thoughts and views on this topic have not changed at all: it's critical for any organization to have a holistic, comprehensive strategy and view of how they support their IT infrastructure and datacenter environments. In fact, I believe it's even more critical today then it was a year ago ...

As a group of concepts, DevOps has converged on several prominent themes including continuous software delivery, automation, and configuration management (CM). These integral pieces often form the pillars of an organization’s DevOps efforts, even as other bigger pieces like overarching best practices and guidelines are still being tried and tested. Being that DevOps is a relatively new paradigm - movement - methodology - [insert your own label here], standards around it have yet to be codified a...

Hosted PaaS providers have given independent developers and startups huge advantages in efficiency and reduced time-to-market over their more process-bound counterparts in enterprises. Software frameworks are now available that allow enterprise IT departments to provide these same advantages for developers in their own organization. In his workshop session at DevOps Summit, Troy Topnik, ActiveState’s Technical Product Manager, will show how on-prem or cloud-hosted Private PaaS can enable organ...

For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...

Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...

Our guest on the podcast this week is Jason Bloomberg, President at Intellyx. When we build services we want them to be lightweight, stateless and scalable while doing one thing really well. In today's cloud world, we're revisiting what to takes to make a good service in the first place. Listen in to learn why following "the book" doesn't necessarily mean that you're solving key business problems.

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...
