Minimalistic State Machine: Less is More
01 Apr 2014

I have tried a bunch of ActiveRecord’s state machine gems. Their functionality is very close to each other. It allows to validate a state transition and reinvent ruby programming language to define transition methods. The fact that all of them produces custom API to define a ruby method doesn’t look right…

Support validation through ajax in Rails 4.x
24 May 2013

I have a constant feeling that in a modern web every web form should be submitted with AJAX not the old retro way with POST request. This is better for numerous reasons.

At first, it gives better user experience At second, AJAX is faster than regular request. At the end, it doesn’t require a work to redraw the page with it’s previous state if validation fails.

Currently I am trying to make rails app support this out of the box. And here is first small step to this goal:

This patch allows a complete validation though ajax using active model validators. This is a live demo of what it allows to do. If you feel especially interested in this feature, say your +1 here or on github.

Attach git commits to pivotal stories
08 Apr 2013

I heard about 10 different ways to organize work flow around pivotaltracker and git and about 5 gems to support that process. All of them seems abusing for me: the outcome of pivotal/git integration is a git commit attached to pivotal story and the rest of conventions like naming branches or merge policy doesn’t make any sense in long time perspective and is just a waste of time in fact.

That’s why I’ve decided to make the most trivial integration that covers this idea and don’t provide additional complexity: Meet git-storyid gem - the only one git/pivotaltracker integration that saves your time.

Where to work as a rubyist in Ukraine
15 Feb 2013

Last year I had a lot of changes in my career: I had to switch jobs twice while planning to do it only once. Most of the projects I was working on before was about building time wasting features to raise more money for more time wasting features. I wanted to find the right project for myself: A project that brings something good to people. Ruby is extremely good for startups, but easy investments is a decease for most of them in Ukraine. In September I met Allan Grant, CEO of Curebit. Curebit has a great team of sales and marketing people but was lacking great engineers. Allan was the first business guy in my life that was more focused on building product than raising money — build features endless cycle. So we started to work together.
