This course is a deep exploration of building applications in MongoDB (the most popular NoSQL document-database). There are many benefits to choosing a NoSQL database over traditional RDMBSs such as SQL Server or Oracle. This course starts out by looking at why you should choose NoSQL in the first place. We will explore the native query language and capabilities of MongoDB. Then we will start working with MongoDB from our .NET applications and look at several topics that explore the advanced aspects of the MongoDB .NET API including (MongoDB from .NET, Advanced serialization in .NET, Untyped API in .NET via BSON documents, and more). We will see how to leverage the immense scalability of MongoDB using the aggregation framework, replica sets, and sharding. You will discover how to store and manage files of virtually unlimited size in MongoDB using GridFS. We will discuss how to properly design your entities and documents (both natively and in C#) to take full advantage of what MongoDB has to offer. Finally, we will round out the course with a few topics that you will need to be successful with MongoDB including Server administration for developers and Security and permissions.
During this class, you will learn:
Learn why you should consider NoSQL as your database.
Discover the MongoDB shell and ‘native’ query language and capabilities
Work with MongoDB from .NET and LINQ
Design your classes and entities to take full advantage of MongoDB
Build and tune high performance applications with indexing and profiling
Use the extensive .NET serialization API to go between .NET and MongoDB
Work with the filesystem (GridFS) within MongoDB from .NET
Answer complex questions while leveraging MongoDB’s scalability using the aggregation framework
Learn enough to administration MongoDB servers to be productive
Scale out using sharding and replica sets
Add security and permissions to MongoDB
Note: Some of the topics cover in this course are technology agnostic (for example the native query lesson is equality applicable to .NET developers as well as Python developers) and some are specifically optimized for .NET developers (for example Advanced serialization in .NET).
Why should you choose DevelopMentor’s MongoDB course? At DevelopMentor we have experience building and running large scale MongoDB deployments in .NET including our online training platform LearningLine and develop.com itself. The course authors work closely with the MongoDB team and are in the MongoDB Masters program. We have been teaching MongoDB in our Guerrilla .NET course for several years. In short, we we know what we’re doing with MongoDB and .NET and we’d love to share it with you.
I recently had a conversation with someone who is looking to make a fresh start and become a developer (coming from other IT positions). The question they had was:
What should I learn to get started in .NET and web development?
Now this question was starting from a position of “I’d like to get started with .NET and the web. How do I do that?” So please hold your “No, choose Ruby (or NodeJS or … )” comments. That’s another blog post. :)
Here’s my advice along with a bunch of courses you can use to accomplish this efficiently and affordably. Continue reading →
[Note: reblogged from blog.learninglineapp.com. I'd like to personally invite you to check out our work over at LearningLine - just follow the links below.]
We believe that LearningLine is the most effective online training for developers, period. Today it gets even better. We are announcing the ability to preview any of our online courses, for free without entering any payment information.
This is not a trial that becomes a subscription or a silly 5 minute preview like other company’s offer. You can now study approximately the first hour of any one of our courses. And you can spend as much time as you like doing so.
This means there is now a lot of content available to you right now. At a typical student speed working for an hour a day, it would take over a month to complete all the content that is available for preview. Continue reading →
Important note: In order to run this demo, you must download MongoDB and start it on your local machine. You do not need to initialize a database or anything like that but the db will be empty so use the admin feature to create categories and books. Running MongoDB as a Windows Service is not required.
At DevelopMentor we have been thinking deeply about online training. We wanted to create an environment that combines the best parts of online learning and classroom training, the best parts of self-directed exploration and expert-led mentoring. We believe we have created just such an environment and I am thrilled to publicly announce it today.
Want to see some of the topics covered in my blog presented live and in-person? Make your way to London in March 2013 to DevWeek! I’ll be presenting 4 sessions covering NoSQL, ASP.NET MVC, and Cloud (Auzre and AWS mostly). Details below.
Just a quick announcement for an developer upcoming event I’ll be participating in…
Early November I’ll be co-teaching DevelopMentor’s biggest .NET developer event of the year in Los Angeles: Guerrilla .NET. If you haven’t been to Guerrilla .NET, it’s a very unique and memorable event – it’s unlike almost any other training class you’ve seen. We’ve just updated the outline with the most important current and upcoming technologies (see below).
Newly Updated with: Windows 8, VS 2012, MVC 4 and Entity Framework 5.
Guerrilla .NET provides a deep exploration of .NET design philosophy and practical advice. You learn a myriad of patterns and best practices, and you get hands-on experience developing applications using Visual Studio 2012 and Windows 8. Learn to write code using new .NET class libraries like Entity Framework 5, MVC 4, and even the new Windows Runtime (WinRT).
Course Topic Highlights:
Windows 8 For The Developer
LINQ and Entity Framework 5
ASP.NET MVC 4.0: Beyond the Basics
Introduction to jQuery
Model-View-ViewModel for WPF and Metro
Building RESTful Services with The ASP.NET Web API
Programming Win8 Apps: Metro / WinRT
Entity Framework 5 and Code First
PFx: Task: a Unified Threading API
PFx: The Parallel Class and Concurrent Data Structures
What’s New in .NET 4.5
Cloud Computing for the .NET Developer: IaaS, PaaS, and Patterns
With Guerrilla .NET from DevelopMentor coming up on May 7th, it’s time to refresh my .NET reading list.
Want to get ready for this class or a class like it or just get a quick-start on .NET? Here’s what I would recommend. There are many books covering the topics (but no small list covering most). Instead of trying to read them all in-depth (a fairly unattainable goal), I would suggest that you read the first 2 – 3 chapters from all of these books listed below. This would cost about $250 if they buy them all, but they are all available on Safari Books Online.
In this webcast we will explore the powerful features of ASP.NET MVC that allow us to build rich forms that accept user input. We’ll begin by discussing the built-in HTML Helpers and Model Binding. Next we’ll add validation and show how we can do both client- and server-side validation using DataAnnotations. Finally, we’ll see that sometimes using domain models as our form-bound objects doesn’t make sense. We’ll look at more advanced scenarios using View Models.
Recently Llewellyn Falco and I did a webcast for DevelopMentor where we demonstrated some TDD techniques and introduced Approval Tests. We let the audience choose our project and they chose Space Invaders. It was all great fun. Now the videos and MP3 streams are online and available for download.
Be sure to check out the write-up we did afterward where we talked about the tools and gave you a chance to try it for yourself:
Tuesday, October 27, 2009 at 10am Pacific time Llewellyn Falco and I will be giving a live, unscripted, and no safety-net demonstration of Test Driven Development (TDD) as part of the DevelopMentor webinar series (this particular series is a 3-part series on Agile development).
We already have a bunch of attendees registered. But we have room for as many of you who are interested in agile and TDD. Sign up here:
In addition to core TDD techniques, you will see how an amazing technique and set of tools designed by Llewellyn called Approval Tests makes writing tests as simple as verifying an image or text file. Tired of writing 50 lines of test code for every 50 lines of production code but you still want the power of TDD? You need to learn more about Approvals and we’ll demo that live tomorrow!
I hope to see you all online. Feel free to help me get the word out by tweeting this or shouting it (see icons below).
Twitter has become one of the web’s hottest properties. It is a central part of mainstream news programs such as CNN’s Anderson Cooper 360, congressional debates, and talk shows. In fact, it grew at a rate of 1400% this past year [bit.ly/jG9BG].
If your company wants to interact with your customers in a modern and engaging experience, you need to be on Twitter. In fact, if you have customers that really like or dislike you, they are probably talking about you on Twitter. You should be part of that conversation.
In this article, we will explore how to build a rich interactive experience on Twitter that goes beyond just creating a new Twitter account. We will build a .NET application that uses the Twitter API (a free service) alongside other cool technologies such as the WCF REST Starter Kit [http://bit.ly/v8mBb] and LINQ to fully leverage the Twitter experience.
When I started out with unit tests, I was enthralled with the promise of ease and security that they would bring to my projects. In practice, however, the theory of sustainable software through unit tests started to break down. This difficulty continued to build up, until I finally threw my head back in anger and declared that
“Unit Tests have become more trouble than they are worth.”
So we stopped. Not all once, but over the months our unit tests died a quiet death. When tests would stop working, we just ignored them. When new features were reported, they were developed without unit testing. At first, it seemed great. We were able to move without the baggage of maintaining the old tests! But soon all the original problems of having a system without tests came back to us. Things keep breaking, deadlines were increasingly pushed back. Releases came with an extraordinary amount of stress, late nights & weekends. The final straw came when we were forced to rush out an immediate update, and ended up taking down the company for 2 days straight. Our new motto became:
“Unit Testing: you’re damned if you do, you’re damned if you don’t.”
In the end, we decided that despite the hardship caused by maintaining unit tests, it just wasn’t feasible to operate without them. So we started down the road to re-incorporate testing into our software development process. As the months went by, however, we discovered that the hardships we remembered had not returned. Looking back, we realized that we had made many mistakes the first time around. The second time around we were smarter. So you, too, can enjoy the benefits of unit tests here are the 5 major pitfalls we encountered the first time around, and how you can avoid them.
