Why it's the right time to learn TypeScript.

In Today's world, If you are an web developer and you don't know JavaScript then you will feel left behind. It's never been a good time to be a JavaScript developer than now. With the rise of Node.js  JavaScript is everywhere now. But as you know when Size and Complexity of your JavaScript is Increased it's very difficult to maintain and mange. That's where TypeScript comes into picture. It is a life saver some times. So in this blog post we will see Why It's the right time to learn TypeScript.

What is TypeScript?

TypeScript is a free and open sourced programming language developed and Maintained by Microsoft. It works as a super set of JavaScript. As we all know that JavaScript is very liberal language by nature. So that we tend to make more mistakes and we does not know all the errors at run time. TypeScript is a strict super set of JavaScript so that you can get most of errors at compile time only.  As per official website of TypeScript it's a language that lets you write JavaScript in the way you really want to. TypeScript offers all the features that you need for Object oriented programming. You can find more information about TypeScript on it's official web site on below link.

http://www.typescriptlang.org/

ECMAScript and TypeScript:

ECMAScript is the specification standard of the JavaScript. So right not standard stable version if ECMAScript 5 and some of the browsers support ECMAScript 6. ECMAScript 6 features are being adopted by latest browsers.While TypeScript follows most of syntax of ECMAScript 6 so that you don't have a feel of the learning new language. As per official road map of Typescript 1.6 comes with ES6 Generator so you can convert your script code into ECMAScript6. Your can find more about that on following blog post.

TypeScript is everywhere:

As we know TypeScript is a fully Object Oriented language, It's provide great productivity boosts than JavaScript and it's super set of JavaScript so it will be compiled into JavaScript itself. So because of this lots of great framework started using TypeScript like following.

1. Angular JS
2. Iconic Framework for creating frond end mobile App
3. Native Script from Telerik is also completely written TypeScript itself.

Take a example of AngularJs, It is one of the most popular JavaScript Framework on earth. With Angular.js 2.0 it will be fully written with TypeScript.

Tooling:

Most of Web Development editor whether it's paid or free are having TypeScript tooling.  Most popular editors like Visual Studio, Visual Studio Code, WebStorm, Atom, Sublime text and Eclipse are having great tooling for TypeScript.

Why to use TypeScript:

Followings are reason why we should use TypeScript instead of JavaScript.

1. Fully Object Oriented support with classes and interfaces. So It's a great productivity boost for any developer and easily maintainable and understandable.
2. It's provide most of the errors compile time while JavaScript is more liberal than this. So less run time error means less bugs for your application.
3. Refactoring is very easy in TypeScript compare to JavaScript.

So it's never been late. It is the right time to learn TypeScript. Hope you like it. Stay tuned for more!.

SQL Server- Guest Post - Solutions for SQL Server Master Database Corruption

This blog post a Guest Post from one of my friend Priyanka Chouhan.

About Author:

Priyanka Chouhan is a technical writer in “Stellar Data Recovery “with 5 years of experience and has written several articles on SQL. She has the fine knowledge of SharePoint and SQL Server. In the spear time she loves reading and gardening.

Here is the her blog about - Solutions for SQL Server Master Database Corruption

Master database is a backbone of the SQL Server database. It is a must have database and user cannot start the SQL Server without master database. It contains the all information about server configuration. When a user installs a SQL Serverthen, it usually creates master, model, MSDB and TEMPDB system databases by default. MSDB and TEMPDB depend on the version of SQL Server database. All system databases performs the different task like: master database is used to store all system level information, TEMPDB stores the information about temporary tables and temporary stored procedures, model is worked as a template for all system created database and MSDB is used by the SQL Server Agent to schedule alerts and jobs.

Corruption in the master database is not a new thing. I will advise to all database users to take the backup of master database because without master database, SQL Server cannot be started. If corruption is high in the master database then SQL Server does not allow starting the database. In this case user can rebuild it by using command prompt or restore from the latest backup (Scroll down to see detailed information). In case of minor corruption, it might be possible that user may start the database but SQL server does not allow to access the details inside the database.

Restore from the Backup

These are the steps to restore the master database from the backup:
• Start SQL Server Configuration Manager then click on the SQL Server Services.
• Stop SQL Server Agent (it might connect first and prevent you to connect as a second user).
• Right-click SQL Serverandthen click Properties.
• Advanced tab, in the Startup Parameters box, insert –mto start the SQL Server in the Single User Mode.
• Now Start SQL Server.
• Start cmd.exe from start menu
• Type SQLCMD on command prompt
• Restore the master database using command:
RESTORE DATABASE master FROM DISK = ‘D:\MyFolder\master.bak’ WITH REPLACE
• Now remove the startup parameter –m.
• Start SQL Server.

This is the best way to fix master database corruption issues. If backup of corrupt master database is not available then user can easily rebuilt it by following below steps.

Rebuild System Database

Rebuild the system database means we are going to drop the re-create in their real location.

• Open the command prompt and change the directories to the location of setup.exe file on the local server. Its default location in the server is C:\Program Files\Microsoft SQL Server\130\Setup Bootstrap\Release.
• Enter the following command in the command prompt Setup
Setup /QUIET /ACTION=REBUILDDATABASE /INSTANCENAME=Instance_Name /SQLSYSADMINACCOUNTS=accounts [ /SAPWD= StrongPassword ] [ /SQLCOLLATION=Collation_Name]
• Once the rebuild process completes then it returns the command prompt without any message. User can view the Summary.txt log file to verify the process. The default location of theSummary.txt log file is C:\Program Files\Microsoft SQL Server\130\Setup Bootstrap\Logs.

Conclusion:

These are the methods to solve the corruption in the master database. Sometimes antivirus software can be the reason of master database corruption. So read the guidelines here to choose the antivirus https://support.microsoft.com/en-us/kb/309422/en-us

Dependency Injection with Autofac: Keyed Registration

This will going to be a fifth post in my Dependency Injection series with Autofac. If you have not gone through all the previous post of this series then I would like to encourage you to go through it. Following is a list of blog posts.
Dependency Injection with Autofac : Getting Started
Dependency Injection with Autofac : Constructor Injection
Dependency Injection with Autofac : Module Feature
Dependency Injection with Autofac : Registration Ordering
Dependency Injection with Autofac: Named Registration

Keyed Registration:

There are multiple ways of register and resolving type in Autofac and keyed registration is one of them. Just liked named registration here you can resolve a type with a key. That key can be a valid C# object. Let’s create a sample console application for it. I have added reference of Autofac via NuGet package as did in my previous blog post. Following is a Customer class that I’ve created for the Keyed registration demo.


After creating Customer class following is a code that I’ve written for demo of Keyed Registration with Autofac.
If you see above code carefully, You can see that first I have created a object of customer as keyCustomer then I’ve register customer type with that keyCustomer Object.  After that I’ve resolved customer with that keyCustomer object and assigned few properties and then Print that customer with “PrintCustomer” object.

One thing to note that when you register type with Keyed Registration It can not be resolve without it. You can only resolve that type with same key you have registered.

Now when you run this application. You will following output as expected.


That’s it. Hope you like it. Stay tuned for more!!.
