What is Node.js and why you need to Study about Node.js

Node Js is a open source and cross-platform runtime environment for executing JavaScript code outside of a browser quite often we use no to build back-end services also called api's or application programming interfaces these are the services that power our client applications like a web app running inside of a web browser or mobile app running on a mobile device these client apps are simply what the user sees and interacts with they're just the surface they need to talk to some services sitting on the server or in the cloud to store data send emails or push notifications kick off workflows and so on node is ideal for building highly scalable data intensive and real-time back-end services that power our client applications now you might ask but mosh there are other tools and frameworks out there for building back-end services such as a speed a bed rails Django and so on so what's so special about no well nodejs is easy to get started and can be used for prototyping and agile development but it can also be used for building super fast and highly scalable services it's used in production by large companies such as PayPal uber Netflix Walmart and so on in fact at PayPal that rebuilt one of their Java and spring based applications using node and it found that the node application was built twice as fast with fewer people in 33% fewer lines of code and 40% fewer files and more importantly they double the number of requests served per second while decreasing the average response time by 35% so node is an excellent choice for building highly scalable services another reason for using nodejs is that in node applications we use JavaScript so if you're a front-end developer and know JavaScript you can reuse your JavaScript skills and - a full-stack developer and get a better job with better pay you don't have to learn a new programming language also because you can use JavaScript both on the front end and on the back end your source code will be cleaner and more consistent so you will use the same naming conventions the same tools and the same best practices and finally another reason for using node is that it has the largest ecosystem of open source libraries available to you so for pretty much any features or building blocks you want to add your application there is some free open source library out there that you can use so you don't have to build this building blocks from scratch and instead you can focus on the core of your application next we're going to look at the architecture of node. Thank you for watching my node tutorial.

Running a Successful Facebook Page - 5 Ways to get likes

1. Choose the Theme and the Name    First step is deciding what your Facebook fan page would be about and naming it right. If you run a site or a blog, you should be naming your page the same, so it would make your business popular. This name will help your customers find you while they search or even accidentally come across. There is a 25 character limitation on the fan page name, but short names are better remembered, so good! 2. Great URL and Greater Description    You’d want to consider giving your page a fancy URL. This will look good while helping customers remember who you are. Description is the ‘About’ column on the page that will talk about your site, your business and provide a link to view it as well. 3.

Beware of the Facebook Account Hackers

I was checking my facebook profile last week when this message saying hackers finding new ways of hacking the accounts of the users caught my attention. So I checked my settings, reset them, changed the user id and password as per the specifications. I still wanted to find out more. So i just googled the words, facebook hacking on Google and was shocked to find out many links that provided ways to successfully hack peoples facebook accounts, boasting of a guaranteed access to other persons account.  Even to think that there are people who are very interested in viewing the details of the other person gives me a sickening feeling. And these people are most of the times on the friend’s list or acquaintance list of that person’s facebook account. This shows the level of intolerance growing among us. Even greater is the surprise to know that the hackers have so much free time to kill. The value of privacy, dignity and relationships is on a decline. Nevertheless, those of us whose a
