Routable modal dialog in Ember.js

| Comments

I hate using modal dialog when the new content could be easily nested in the same page. I just don’t like the user experience of a popup. Why limit yourself to a small box when you can show it in the full-blown layout?

However, sometimes clients insist on a modal in their design and we have to deal with it. In this blog post I will show you how to make the modal dialog a little bit better – give it its own URL.

Beautiful Ruby, convenient Rails

| Comments

In this blog post I want to reflect on things which make Ruby a beautiful language to read and write, and on things which make Ruby on Rails a convenient tool to quickly prototype.

This is an introductory level blog post.

Using message queue in Rails

| Comments

This post describes the application architecture pattern which is (in general) nothing new, but (from my experience) rarely applied in the Rails world. I’m talking about the nice and simple abstraction – message queue. But let me start by describing the goals I want to achieve and some alternative solutions.

10 easy-to-fix Ruby / Ruby on Rails mistakes

| Comments

Programmers make mistakes. Some of them are just annoying (for others to read) and some are really dangerous. Here is my selection of 10 mistakes done by Ruby / Ruby on Rails developers. These tips are easy to follow and can save you much time of later debugging.

My take on services in Rails

| Comments

It’s been a while since my last post. I was writing my engineer’s thesis which caused general disgust towards writing at all. Anyway, these sad times are over and here comes the shiny new blogpost about introducing service layer in Rails applications. It does not contain any breakthrough thoughts, but is rather a mixture of ideas I learned from great Ruby developers.

Using Lineman.js with AngularJS

| Comments

I’ve recently started playing with AngularJS. Coming from the Rails world I expected a structure enforced by the framework, good default configuration and separation into development, test and production environments.

It seems that the way to start a new project suggested by the creators of AngularJS is to clone angular-seed project. While this seed project worked for me during development and testing, I was a bit lost when it came to deploying to production.

Black-box testing

| Comments

This time I want to share my thoughts concerning two approaches to testing – black-box testing and white-box testing. I gave a talk about it at Lodz Ruby User Group. You can find the slides here.

The presentation took place some time before DHH’s keynote at Railsconf 2014 and before #isTDDDead discussion began. However, there is a connection: DHH encourages to write “higher level system tests” and in this post I express slightly more balanced opinion on black-box testing.

Here you can find a couple of my personal opinions about talks at wroclove.rb 2014 which took place in March 14th – 16th in Wrocław. I tried to keep my feedback 100% positive in order not to upset anybody, but if you are – write a comment and we’ll discuss.

Learn Chef - it’s hard but worth it

| Comments

Recently I’ve been forced by the circumstances to learn Chef. It’s simply not possible to manage about 15 servers without any automation tool. I’m not a master of shell scripting (neither I like it), so using Ruby in this field sounds great to me.
