I wish I could be prepared for all the questions which may come up during the upcoming devcrowd.pl conference in Szczecin, Poland where I’m speaking about developing web applications with Clojure. The aim of the presentation is to show that Clojure can be the language for components in a Java EE application, but can also [...]

Got an email that A monad tutorial for Clojure programmers (part 1) was corrected with the latest changes around clojure.algo.monads. I almost immediately began reading it. It’s been a while since I read it, and recalled how tough it was to understand what monads are and how they work in Clojure. It was at the [...]

Wednesday was great! It was the day at the 33rd degree conference when I ran my presentation and spent another hour presenting Clojure by code samples. There were three people who needed more since I merely scratched the surface of why people should consider Clojure as the language of choice. I could barely present 2 [...]

Functional programming is for me about function composition and no mutable state in-between if possible. I knew I could do better than Drawing a winner in Clojure (in an almost purely functional approach) and the comments showed how far I was from “purely functional approach” (I should’ve known it’s not a good idea to use [...]

There is a need in Warszawa Java User Group to have a way to draw a winner of a free license for a product from JetBrains amongst the attendees of a meeting. We couldn’t figure out whether the draw should be at the beginning of a meeting or its end. Some argued it doesn’t really [...]

I should rather refrain from announcing the blog entry Thinking functional programming with Map and Fold in your everyday Java as it wasn’t at all useful from the point of a person who’s aiming at learning functional programming, however, on the contrary, it did a great job of encouraging me to try out Clojure’s Java [...]

I’ve already described the issue of Can’t dynamically bind non-dynamic var in Can’t dynamically bind non-dynamic var in Clojure 1.3. While learning about defs, symbols and vars, I again ran into this issue. I can see now that I made a mistake using Clojure 1.3 not 1.3.0-alpha6 in the title of the past blog entry [...]
