How Stuff Works - SMTP through WireShark
The SMTP (Simple Mail Transfer Protocol) is an Internet standard communication protocol for electronic mail transmission. Most of mail servers use SMTP protocol to send/receive email messages. Most email clients available today uses SMTP only for relaying messages to another mail server. But Mail client software on your desktop/laptop/electronic devices uses IMAP/POP3 to pull emails from its servers. So in simple terms SMTP is to communicate between/among Mail Server(s) to Mail Server(s). SMTP is implemented upon TCP (Transmission Control Protocol)

Using React’s new Effect Hooks
React has added a new feature named Effect Hooks. So what’s the effect hooks and why were they needed. Effect Hooks allows programmer to use some of the React’s class properties (state and others) without actually extending it, in function component. React class comes with a lot of features but mostly we need is state, props and side effect functions (e.g componentDidMount, componentDidUpdate and componentWillUnmount)

Clustering - Multi-core utilization for Node.JS
While building an application in today’s era; a developer would definitely wish to leverage underlying OS multi-core architecture for performance. Since [JavaScript] is single threaded application meaning that only one thread can run at any given time, hence by default JavaScript can only leverage single core CPU. To come about this, Node.JS has introduced Cluster API. In this article we will have a look at Cluster API, create child processes, and how to use it.

What’s new ECMAScript 2017
Two years ago when ECMAScript 2015 (colloquially known as a ES6) was standardized there was a massive update to the language. Announced at the same time was a yearly release plan that aims to deliver a new version of the language annually and ship it with the proposals that are ready at the time of the TC39 meeting. The list of language improvements is open and you can track it on the TC39 Github account. Following are some noticeable changes in 8th edition or es8 or ECMAScript2017
(JWT) JSON Web Tokens for API
In modern era, Authentication and authorization are used widely in mostly every app out there. While authentication establishesh user’s (or machine’s/thing’s) identity, authorization is way to know what kind of access is that user is granted, marking the periphery one is allowed to wander.
Promises in ES6
In JS world, promises always been a controversial topic. Interestingly, There are lots of libraries out there implementing promise in there own tastes. jquery’s deferred, q, bluebird, deferred.js to name just a few. Opinions conflict over using async, generators, callbacks etc. But thank God; ECMA has now officially implemented promises in ES6. That’s a good news for JS community over having a single standard implementation of promises.

Go has a speciel type struct to define custome type with named fields. Struct act like collection of attributes/properties similar to classes in OOPS languages out there, but not exactly.
Go to Go - Packages
Go is modern language, so it has to take care of current software development practices; code reuse or DRY (Don’t Repeat Yourself) being one of them. In go code can be packed into modules and shipped. Lets look into how go uses packages.
Go to Go - Concurrency Part#2
In last part, where we discussed Golang Concurrency, we talked about goroutines and channels. As discussed there is much more to channels, liked channel direction, by default a channel is bi-directional, but it can be restricted to sending or receiving.
Go to Go - Concurrency Part#1
Go came to existance to solve problems being faced by today’s software, one of them is concurrency (ability to execute stuff in parallel while providing control and communication among them). To solve this go has provided goroutines to execute stuff in parallel.

JSDB - (A JIT interpreter for JavaScript)
Frankly I used to be frightened from working with JavaScript but since I started working with Core JavaScript(in Titanium) my interest grew for this language. I started hacking around the stuff in JavaScript, but being a Ruby developer from heart I do not want to leave command line and to test the code I have written, I needed some sort of compiler or interpreter like Ruby’s IRB. So as usual I hit the Google but for my misery I found nothing.
