I’ve ordered my Raspberry PI, so I’m planning how and what I’m going to be doing with it.
I have many small projects I’d like to get underway, but ones which spring to mind first are building a home Media Centre, Network Storage device that supports many drives, and one that is hot on my list is the ability to connect the Raspberry PI to my Arduino and build a small portable device that can tell me where and how to access Wifi while I’m out and about.
But before I do anything lets get a virtual machine up and running so we can start playing as if we were on the Raspberry PI:
It has been rumoured that Debian will be the preferred OS to use on the PI due to it small foot print, so let go and get it
I selected and downloaded small CDs and the kfreebsb-i386, mainly because I am running on a Mac and will be running my virtual machine inside of Parallels.
Thing to remember when creating your virtual machine is set your memory to 256mg as this is all you’ll have to play with inside your PI.
Here is a YouTube video that I made which goes through the installation of Debian in real time, as it takes under 15 minutes to install
So first steps complete.
The next Blog on the Raspberry PI will be to install a graphical user interface on to your Debian operating system.
I’ve been pushing Balsamiq Mockups for a number of years, it was on my toy list for 2009.
Once you have a mock up of your wireframe and the customer is happy with the look, the next stage is to convert it to HTML, previously I have prefered to pass this to a designer to make it look pretty. But the problem you’ll have with making something look nice is that the customer will think it is DONE and you just don’t want that to happen.
Worth having a look at if you are a beginner or a seasoned programmer.
The C# 4.0-specific samples are called:
Named and Optional
Here is the complete list of language samples:
Anonymous Delegates: Demonstrates the use of unnamed delegates to reduce application complexity.
Arrays: Shows how to use arrays.
Attributes: Shows how to create custom attribute classes, use them in code, and query them through reflection.
Collection Classes: Shows how to make non-generic collection classes that can be used with the foreach statement.
COM Interop Part I: Shows how to use C# to interoperate with COM objects.
COM Interop Part II: Shows how to a use a C# server together with a C++ COM client.
Commandline: Demonstrates simple command-line processing and array indexing.
Condiational Methods: Demonstrates conditional methods, which provide a powerful mechanism by which calls to methods can be included or omitted depending on whether a symbol is defined.
Delegates: Shows how delegates are declared, mapped to static and instance methods, and combined into multicast delegates.
Events: Shows how to declare, invoke, and configure events in C#.
Explicit Interface: Demonstrates how to explicitly implement interface members and how to access those members from interface instances.
Generics: Shows how to make generic collection classes that can be used with the foreach statement.
Hello World: A Hello World application.
Indexers Part I: Shows how C# classes can declare indexers to provide array-like access to objects.
Indexers Part II: Shows how to implement a class that uses indexed properties. Indexed properties enable you to use a class that represents an array-like collection.
Libraries: Shows how to use compiler options to create a DLL from multiple source files; also, how to use the library in other programs
Named and Optional (C# 4.0): Demonstrates Named and Optional parameters, an alternative to method overloads
Nullable: Demonstrates value types, such as double and bool, that can be set to null
Office Sample (C# 4.0): Demonstrates how Dynamic and COM Interop make it easy to call Microsoft Office in C# 4.0
OLEDB: Demonstrates how to use a Microsoft Access database from C# by creating a dataset and adding tables to it.
Operator Overloading: Shows how user-defined classes can overload operators
Partial Types: Demonstrates how classes and structures can be defined in multiple C# source-code files
PInvokeShows how to call exported DLL functions from C#
Properties: Shows how properties are declared and used; also demonstrates abstract properties
Python Sample (C# 4.0): Learn how to call a Python script by using the Dynamic feature in C# 4.0
Security: Discusses .NET Framework security and shows two ways to modify security permissions in C#: using permission classes and permission attributes
Simple Variance (C# 4.0): See how Covariance and Contravariance are supported in generic interfaces and delegates
Structs: Shows how to use structs in C#.
Threading: Demonstrates various thread activities such as creating and executing a thread, synchronizing threads, interacting between threads, and using a thread pool
Unsafe: Shows how to use unmanaged code (code that uses pointers) in C#
User Conversions: Shows how to define conversions to and from user-defined types
Versioning: Demonstrates versioning in C# by using the override and new keywords
XML Documents: Shows how to document code by using XML
Yield: Demonstrates how to use the yield keyword to filter items in a collection
These samples help you learn LINQ quickly. They also act as a reference and guide for those with existing LINQ experience. A few handy utilities are also included. They are available in the LinqSamples folder.
DynamicQuery: Code to create LINQ queries at run time.
LinqToNorthwind: A basic example of how to use LINQ To SQL to query a database
LinqToXmlDataBinding: Bind LINQ to XML code to WPF controls
ObjectDumper: A utility for writing the output from a LINQ query to the screen in text mode
PasteXmlAsLinq: A Visual Studio addin that automatically converts XML to LINQ to XML.
QueryVisualizer: Allows LINQ to SQL developers to see the SQL for their query, and also to see the results of the query in a grid.
Reflector: Use LINQ to right queries against the objects in your code using the Reflection APIs
RSS: This sample acts as a tiny web server that aggregates several RSS feeds
SampleQueries: This is the most important sample and contains about 500 examples of how to use each of the query operators in LINQ to Objects, LINQ to SQL, LINQ to XML and LINQ to DataSet.
SimpleLambdas: Several examples of how to write and use lambda expressions
SimpleLinqToObjects: The hello world of the LINQ samples. This shows you how easy it is to do simple queries of in-memory objects using LINQ to Objects.
SimpleLinqToXml: Get started using LINQ to XML.
