"There are sufficient videos available in the video repositories provided by YouTube and Vimeo to make it difficult locating the good ones. In addition, not all of them are professionally produced. However, InfoQ.com could identify some pearls which are worthwhile watching. We have reviewed what we found and tried to figure out the interesting ones. But, of course, such activities are always driven by the author's taste."

"ORM users have grown accustomed to thinking in terms of .NET and LINQ, forgetting the specifics of particular databases, differences in their functionality and effectiveness of certain SQL-constructions. In this article, we shall briefly discuss some of the problems that the user may face in the process of developing an application for Entity Framework (EF), which is meant to interact with Oracle, MySQL, PostgreSQL or SQLite rather than Microsoft SQL Server. I hope this will be useful both for users who create an EF-application for these databases for the first time as well as for those who create an application that must support interaction with multiple databases, i.e., SQL Server and Oracle. As examples of implementing EF-providers for databases other than SQL Server, we shall use Devart ADO.NET providers."

"The biggest thing in web apps since "rails can't scale" is this idea that "your rdbms doesn't scale." This has gone so far as to be dubbed the coming of age for "nosql" with lots of blog posts and even a meetup. Indeed, there are many promising key-value stores, distributed key-value stores, document oriented dbs, and column oriented db projects on the radar. This is *definitely* a great thing for the web application scene and this level of variety will definitely open doors for organizations large and small in the near and long term."

" Greg Young discusses how to use events to store data, and how testing, versioning and performance are impacted by an event-centered model. "

Sounds like this guy is confuse between enterprise architecture and solutions architecture. Or I am. :)

I think both those roles are evolving quite quickly at the moment. The classic Enterprise Architect is having to find new ways to plan, communicate and check quality as more and more teams explore Agile methodologies. The Solution Architect is suddenly playing a more obvious role as a result of the above. My feeling is, it is not so much about people, but about function. The same person could operate as a Solutions Architect most of the day, but then could get together in some kind of Architect's forum and play the role of an Enterprise Architect. That forum then wrestles through the Enterprise Architect issues and establishes the back-bone on which the Agile Development is done. That's what is probably happening, formally or informally in a lot of dev teams at the moment.

" Howard Lewis Ship talks about Clojure, a language more concise, testable, and readable than Java, letting the developer to focus on his work rather than a verbose syntax. "

"In the world of software management there exists a dread place called "dependency hell." The bigger your system grows and the more packages you integrate into your software, the more likely you are to find yourself, one day, in this pit of despair."

"Socket.IO aims to make realtime apps possible in every browser and mobile device, blurring the differences between the different transport mechanisms. It's care-free realtime 100% in JavaScript."

"Pusher is a hosted API for quickly, easily and securely adding scalable realtime functionality via WebSockets to web and mobile apps."

"SendGrid's cloud-based email infrastructure relieves businesses of the cost and complexity of maintaining custom email systems. SendGrid provides reliable delivery, scalability and real-time analytics along with flexible APIs that make custom integration a breeze."

" Stuart Halloway discusses how we use a total control time model, proposing a different one that represents the world more accurately helping to solve some of the concurrency and parallelism problems. "

" If you develop any serious software, I'm sure you're tired of manual steps required to collaborate among the various tools involved in the process of Agile software development. You need to take a hard look at IBM's Rational Team Concert (RTC) for its ability to facilitate collaboration among the multitude of tools development shops use for managing requirements, stories, code, builds, tests, deployments, issues, defects and all of the various threads that run through a large software development effort. Hint: RTC has legendary Eclipse pedigree."

"It's fair to say that the mere mention of the word REST causes polarisation in people. For a while REST struggled against the WS-* wave and then appeared to have surmounted that obstacle only to start to fall fowl of those people who believe that there is a benefit to be found within REST but perhaps not as much as others might like to believe. One of the main advocates against buying in to the totality of what "RESTafarians" believe is Jean-Jacques Dubray, who recently published an article on what he calls unREST. As JJ begins:"

"Mark Seemann, author of Dependency Injection in .NET, talks to us about the differences between DI and Service Locators and the importance of having a Composite Root. He also touches on how these all relate back to the SOLID principals of object oriented design."

"There is a popular design for a database that requires a built-in audit-trail of amendments and additions, where data is never deleted, but merely superseded by a later version. Whilst this is conceptually simple, it has always made for complicated SQL for reporting the latest version of data. Alex joins the debate on the best way of doing this with an example using an indexed view and the filtered index."

"If you keep your data according to its version number, but need to work only with a particular version, what is the best SQL for the job? Which one works best? Which one do you use and when?"

"Agile development starts to build before the outcome is fully understood, ad­justs designs and plans as empirical knowledge is gained while building, trusts the judgment of those closest to the problem, and encourages continual col­laboration with the ultimate consumers. Architecture establishes a technol­ogy stack, creates design patterns, enhances quality attributes, and communicates to all interested parties. The combination of these two spaces is agile architecture - an approach that uses agile techniques to drive toward good architecture. Successful agile architecture requires an architect who understands agile de­velopment, interacts with the team at well-defined points, influences them using critical skills easily adapted from architectural experience with other approaches, and applies architectural functions that are independent of project methodology."

"Thanks to the NoSQL movement, data storage solutions are no longer a solved problem. Many are working hard to build new storage solutions, and even more are willing to use them. On the flip side, if you are a programmer or a solution architect who wants a data storage solution for your application, you have to face the daunting task of weighing and understanding the tradeoffs associated with the application and make a decision. This article explores the data needs of end user applications and various tradeoffs. It provides guidelines on the criteria for selecting data storage choices enabling the architects and developers to make an informed decision."
