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)

What is Cypress.JS and How to use it

Ever used Selenium? Do you remember installing a language driver to use it or writing tests for it? Cypress is similar to Selenium but comparatively better. It runs your browser and within the same process, it runs tests. Cypress is an End-to-End test suite

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.

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 waitgroup with goroutines

Previously in Golang Concurrency we talked about how goroutines in Go language works. Today we will focus on providing robustness to our previous talk by using semaphores from Golang sync package.

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.

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.
