I’ve been tracking the growth of the new coronavirus ever since it first appeared in China in the last week of January, and even more since it spread to Europe around mid February. Initially I’ve been looking mostly at the popular ArcGIS dashboard made...

The beginning of 2013 was a really bad time for the Ruby community. In the first few weeks of the year a few separate security issues were found that made everyone run to their SSH consoles to update their Rails apps. Rails itself had to be updated 4 times...

If you’ve read the Rails 3.1 asset pipeline docs, you’re probably aware that you can add preprocessors to your asset files by appending extra file extensions. For example, to write your JS files in CoffeeScript you need to add the suffix .coffee, and i...

I started this blog almost 3 years ago. It was a bit of an experiment, as I wasn’t sure if that actually made sense, if I would want to keep writing it a few months later - so I put it on Jogger (Polish Jabber-based blog service) and I used the clas...

For the last 2 months, I’ve been using a new Ruby framework at work. A very… interesting framework :) It looked very promising in the beginning, only to become a complete disaster a few weeks later. I thought I could share some of my experiences wit...
