Group INSERT, UPDATE, and DELETE operations from a DataSet or DataTable

Group INSERT, UPDATE, and DELETE operations from a DataSet or DataTable

Batch support in ADO.NET allows a DataAdapter to group INSERT, UPDATE, and DELETE operations from a DataSet or DataTable to the server, instead of sending one operation at a time. The reduction in the number of round trips to the server typically results in significant performance gains. Batch updates are supported for the .NET data providers for SQL Server (System.Data.SqlClient) and Oracle (System.Data.OracleClient).

public static void BatchUpdate(DataTable dataTable,Int32 batchSize) 

    // Assumes GetConnectionString() returns a valid connection string. 
    string connectionString = GetConnectionString(); 
 
    // Connect to the AdventureWorks database. 
    using (SqlConnection connection = new 
      SqlConnection(connectionString)) 
    { 
 
        // Create a SqlDataAdapter. 
        SqlDataAdapter adapter = new SqlDataAdapter(); 
 
        // Set the UPDATE command and parameters. 
        adapter.UpdateCommand = new SqlCommand( 
            "UPDATE Production.ProductCategory SET " 
            + "Name=@Name WHERE ProductCategoryID=@ProdCatID;", 
            connection); 
        adapter.UpdateCommand.Parameters.Add("@Name", 
           SqlDbType.NVarChar, 50, "Name"); 
        adapter.UpdateCommand.Parameters.Add("@ProdCatID", 
           SqlDbType.Int, 4, "ProductCategoryID"); 
         adapter.UpdateCommand.UpdatedRowSource = UpdateRowSource.None; 
 
        // Set the INSERT command and parameter. 
        adapter.InsertCommand = new SqlCommand( 
            "INSERT INTO Production.ProductCategory (Name) VALUES (@Name);", 
            connection); 
        adapter.InsertCommand.Parameters.Add("@Name", 
          SqlDbType.NVarChar, 50, "Name"); 
        adapter.InsertCommand.UpdatedRowSource = UpdateRowSource.None; 
 
        // Set the DELETE command and parameter. 
        adapter.DeleteCommand = new SqlCommand( 
            "DELETE FROM Production.ProductCategory " 
            + "WHERE ProductCategoryID=@ProdCatID;", connection); 
        adapter.DeleteCommand.Parameters.Add("@ProdCatID", 
          SqlDbType.Int, 4, "ProductCategoryID"); 
        adapter.DeleteCommand.UpdatedRowSource = UpdateRowSource.None; 
 
        // Set the batch size. 
        adapter.UpdateBatchSize = batchSize; 
 
        // Execute the update. 
        adapter.Update(dataTable); 
    } 
}

JSLint tools for Javascript

JSLint tools for Javascript

JSLint is a JavaScript program that looks for problems in JavaScript programs. It is a code quality tool.

JSLint takes a JavaScript source and scans it. If it finds a problem, it returns a message describing the problem and an approximate location within the source. The problem is not necessarily a syntax error, although it often is. JSLint looks at some style conventions as well as structural problems. It does not prove that your program is correct. It just provides another set of eyes to help spot problems.

JSLint defines a professional subset of JavaScript, a stricter language than that defined by the ECMAScript Programming Language Standard (the strangely named document that governs JavaScript). JSLint will reject most legal programs. It is a higher standard.

JavaScript is a sloppy language, but hidden deep inside there is an elegant, better language. JSLint helps you to program in that better language and to avoid most of the slop. JSLint will reject programs that browsers will accept because JSLint is concerned with the quality of your code and browsers are not. You should gladly accept all of JSLint's advice.

ReSharper tools in dotnet

ReSharper tools in dotnet

ReSharper is a popular developer productivity extension for Microsoft Visual Studio. It automates most of what can be automated in your coding routines. It finds compiler errors, runtime errors, redundancies, and code smellsright as you type, suggesting intelligent corrections for them.
ReSharper helps you explore code by visualizing the structure of files, type and style hierarchies, call and value chains, project dependencies. It allows you to instantly traverse your entire solution and jump right to the exact file and line that you are looking for, decompiling library code if necessary.
Dozens of solution-wide refactorings are available to help you safely change your code base. Code formatting and cleanup features allow you to get rid of unused code and help your entire team to ensure compliance to coding standards.

Why ReSharper

With unparalleled support for C#, VB.NET, XAML, JavaScript, TypeScript, XML, HTML, CSS, ASP.NET, ASP.NET MVC, NAnt and MSBuild scripts including comprehensive cross-language functionality, ReSharper will help any Visual Studio user write better code, easily examine and refactor existing code bases.
You can spend less time on routine, repetitive manual work and instead focus on the task at hand. A robust set of features for automatic error-checking and code correction cuts development time and increases your efficiency. You'll find that ReSharper quickly pays back its cost in increased developer productivity and improved code quality. With ReSharper, .NET developers can truly experience what we mean when we say "Develop with pleasure!"

What is Bitcoin?

Bitcoin

Bitcoin was invented in 2008. Since that time, the Bitcoin blockchain has operated without significant disruption. (To date, any of problems associated with Bitcoin have been due to hacking or mismanagement. In other words, these problems come from bad intention and human error, not flaws in the underlying concepts.)

A network of so-called computing “nodes” make up the blockchain.

Nodes

(computer connected to the blockchain network using a client that performs the task of validating and relaying transactions) gets a copy of the blockchain, which gets downloaded automatically upon joining the blockchain network.


Together they create a powerful second-level network, a wholly different vision for how the internet can function.

Every node is an “administrator” of the blockchain, and joins the network voluntarily (in this sense, the network is decentralized). However, each one has an incentive for participating in the network: the chance of winning Bitcoins.

Nodes are said to be “mining” Bitcoin, but the term is something of a misnomer. In fact, each one is competing to win Bitcoins by solving computational puzzles. Bitcoin was the raison d’etre of the blockchain as it was originally conceived. It’s now recognized to be only the first of many potential applications of the technology.

There are an estimated 700 Bitcoin-like cryptocurrencies (exchangeable value tokens) already available. As well, a range of other potential adaptations of the original blockchain concept are currently active, or in development.
