Category: Programming

A big part of my work has to do with code. I’ve worked as system administrator – installing, patching, and configuring someone else’s code. I’ve worked as independent programmer, writing code on my own. I also programmed as part of the team. And on top of that, I worked as Team Leader and Project Manager, where I had to interact a lot with programmers. Programming world on its own is as huge as the universe. There is always something to learn. When I find something worthy or something that I understand enough to write about, I share it in this category.

Vue.js — answering the Why, after 15 months

Harshal Patil shares his positive experience with the Vue.js JavaScript framework, after using it for just over a year in “Vue.js — answering the Why, after 15 months“.  As many before him, he focuses on the virtual DOM, optional but powerful build system, state management, single file components, performance, testability, and a few other benefits of this particular technology.

It’s good overall article for those who are still deciding which JavaScript framework to go with for their next project.

Winamp2-js – implementation of Winamp 2.9 in HTML5 and JavaScript

Atwood’s Law states that any application that can be written in JavaScript, will eventually be written in JavaScript.  Winamp2-js is yet another example supporting this law.  It is a re-implementation of Winamp 2.9, a classic Windows MP3 player from decades ago, done in HTML5 and JavaScript.

The source code is on GitHub and a live demo is available here.

A Practical Introduction to Container Terminology

“A Practical Introduction to Container Terminology” is at the same time two things for me:

  1. The longest blog post that I’ve seen in a long time, if not ever.
  2. The best introductory tutorial into containers.

Strongly recommended.

Nginx 1.13.9 and HTTP/2 Server Push

Here are some very exciting news from the Nginx front lines: HTTP/2 Server Push is now available in the latest and greatest Nginx 1.13.9, which was released yesterday!

Server Push was one of the most exciting features for me in all of the HTTP/2 specification.  But I wasn’t quite sure how it will be implemented, and, most importantly, how it can be made easily available to the web developers, who are often few levels removed from the web server configuration.  I think Nginx solves the problem quite elegantly.

On the configuration level, “location” directives are often available to the web developers withing the virtual host / server.  But for those who can’t use those or don’t want to mess around with the configuration files, an even easier option is available – Link HTTP header.

I’m sure this will soon be widely supported in all the major libraries and frameworks, much like HTTP cookies are.   Great times ahead!
