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....

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!...

Actually, it was done some time ago but I think it’s time to make it more official. This blog was finally migrated from outdated blogengine.net to new Hugo. There is still a log of work in progress: restore images, fix theme, RSS and re-enable comments. I hope, it’ll help me to create more awesome posts this year.

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....

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. CKAN makes it easy to publish, share and use data. It powers datahub.io, catalog.data.gov and europeandataportal.eu/data/en/dataset among many other sites. http://ckan.org/ Open source world is interesting and challenging. Sometimes it’s easy and cheap. Sometimes it’s hard to contribute and costs a lot. Looking into the CKAN I was surprised that it’s used by government portals. That’s why I tried to use it a bit....
Remote console via SSH with own bashrc
Published at August 9, 2017 · 1 min read
I think, most of us have customized bash or zsh environment. I’m too lazy to switch from bash to zsh, so I use bash on my laptop. There are some benefits: bash is still the more popular shell, so it exists on mostly Linux-based servers. That’s why I try to use my .bashrc wherever it’s possible. But on a remote server, sometimes you don’t have the own user account. That’s why I’ve added a very simple alias for ssh command to mine [....

Sometimes we need to understand why unit-test is so slow. Sometimes I’m to lazy to go deep to understand why. That’s why I’ve created a very simple profiled class to make unit-tests profiling fast and simple. I used only cProfile, so it will work on any Python project. It’s so simple, so I can’t talk about it more. You can install it via ‘pip install ProfiledTest’ and use it like:...
