Algorithmic Music Composition [paper]

December 11, 2014

After I wrote my first post about, many were interested in the code. Then I open-sourced it. And now, to complete my contribution, I wrote a paper about my approach and findings. The paper is on and also on arxiv. I’d be happy to get honest peer reviews. It’s not a great novelty, […]


Making Side Projects With New Technologies

November 22, 2014

(Captain Obvious mantle on) You are a software engineer and maybe you have a side project – something that you do at home in your spare time. If you don’t, go ahead and have one – no life outside is better than a few more hours of programming. Unwitty jokes aside, having a side project […]


Development Overhead

November 13, 2014

What does a developer spend his time on? Writing code, debugging, thinking and communicating with colleagues (that includes meetings). Anything that is beyond these activities is unnecessary overhead (some meetings are also unnecessary, but that’s a different topic). And yet, depending on our language and tools, we have to do a lot more to support […]


The DSL Jungle

October 21, 2014

DSLs are a common thing in the programming world nowadays. Many frameworks and tools decide to build a DSL for their…specific things. Builds tools are the primary candidates, but testing frameworks, web frameworks and whatnot also decide to define a DSL. With these DSLs you define build steps, web routing rules, test acceptance criteria, etc. […]


Scala – the Good, the Bad and the Very Ugly [presentation]

October 6, 2014

The other day I gave a talk on a tech conference about my experience with Scala. Ironically, just two weeks after I wrote that I don’t like Scala, I started working with it on a daily basis, so I now have a better overview. And it’s not all black and white, but many of my […]


Musical Scale Generator

September 7, 2014

We all know the C-major scale: do-re-mi-fa-sol-la-ti-do. But what’s behind it? And how many other scales there are? It’s complicated. Let me do a brief introduction into the theory first, without trying to be precise or complete. In use are more than a dozen scales, and the popular one in the western world are the […]


Get Rid of the URL Pollution

August 13, 2014

You want to copy the URL of a nice article/video/picture you’ve just opened and send it to friends in skype chats, whatsapp, other messengers or social networks. And you realize the URL looks like this: What are these parameters that pollute the URL? The above example uses some of the Google Analytics parameters (utm*), […]


Suggestion for Spam Filters

August 4, 2014

One of the issues with spam is false positives. “Did you check your spam folder” is often a question to ask if your email is not received on the other end. I’m not a machine learning expert and I’ve never made a spam filter, and I only know the naive Bayes approach. So this suggestion […]


The Cloud Beyond the Buzzword [presentation]

July 14, 2014

The other day I gave a presentation about “The Cloud”. I talked about buzzwords, incompetence, classification, and most importantly – embracing failure. Here are the slides (the talk was not in English). I didn’t have time to go into too much details, but I hope it’s a nice overview.


You Probably Don’t Need a Message Queue

July 3, 2014

I’m a minimalist, and I don’t like to complicate software too early and unnecessarily. And adding components to a software system is one of the things that adds a significant amount of complexity. So let’s talk about message queues. Message Queues are systems that let you have fault-tolerant, distributed, decoupled, etc, etc. architecture. That sounds […]
