I'm too lazy to not use Bootstrap

Published at January 9, 2019 ·  2 min read

I never liked hit with CSS. I hate to deal with HTML make up a lot. I prefer to work with JavaScript and omit styles if possible. Maybe it’s only because I’m not an expert in this area. That’s why I use Bootstrap framework where it’s possible. It allows everybody to create pretty good UI’s for web application with minimal knowledge of styles and CSS. In a real word, I don’t even want to use Bootstrap directly in web applications based on modern libraries and frameworks like React and Vue....

Vue.js + Python API + Docker in Development Environment

Published at January 8, 2019 ·  3 min read

NOTE: All things described in this post could be not 100% correct. I just described my development environment for a simple project with JavaScript fronted and Python backend.

Any contributions are welcome! Intro It’s a story about how I tried to create a simple development environment for web project with Python-based backend and frontend written on Vue....

Minimal OpenStack Cinder setup

Published at January 7, 2019 ·  2 min read

During OpenStack Cinder development you may want to have some minimal working configuration to run the only Cinder on your environment. If you don’t need to test full volume attach flow with Nova, you may need to run only Cinder(cinder-api, cinder-scheduler, and cinder-volume, even cinder-backup is optional), RabbitMQ, and MySQL. Usually, for Cinder development, I don’t need full OpenStack up and running on my virtual machine. I just need to have only Cinder itself and such required things like database and message queue....

Click and Double Click in JavaScript

Published at January 5, 2019 ·  1 min read

Spent a few hours on a simple task: create different handlers for ‘click’ and ‘double click’ events on the same element, onclick handler should not be executed if a double click event is raised. I hope, there is a better solution but I didn’t find it. I leave it here in case if somebody helps me with it: <html> <body> <a href="#" id="clickMe">Click Me</a> <script type="text/javascript"> /* click or double click */ var timeout = null; let link = document....

Pros and Cons of Vue.js

Published at January 2, 2019 ·  3 min read

Since I started to learn Vue.js a few months ago, I realized that it has some benefits I like and some things which I really hate. I’m not an expert in this framework, but I would like to share my thoughts about it. Pros: Simplicity It is really easy to integrate it into your existing web application by just adding one more ~20KB-size JavaScript library. It allows you to start using it with an old or legacy web site like you did with jQuery in the past!...

Most of the information you can get using the following three commands: lspci - list all PCI devices lshw - list hardware dmidecode - DMI table decoder Using multiple keys to these CLI tools you can get everything you need....
