How I use a vision AI model and Obsidian to turn a messy folder of miniature painting reference images into a searchable, tagged catalog.

A two-minute Windows Terminal tweak that makes Shift+Enter insert a new line in Claude Code instead of submitting your prompt.

Emacs is amazing text editor (let's treat it as a fact ;) ), but it can become clunky in some situations.

Usually once a year I get a new license for NDepend from Patrick Smacchia - its creator.

It became a tradition for me that in September I go to Krakow to participate in DevDay conference.

The latest version of Clojure (1.8) introduced a new set of functions operating on strings.

I wonder why max-key and min-key in Clojure are not named max-by and min-by.

In addition to commonly known reduce function Clojure has its specialized version called reduce-kv.

I could safely say that map, reduce and filter are the most commonly used functions in Clojure (and probably other functional languages).

The common thing in functional programming is combining "smaller" functions into the bigger one ( higher-order functions ).

The threading macros (-> and ->>) provide easy to understand and read mechanism of sequential transformation of data in Clojure.

Today I finally published my Emacs configuration to GitHub.

we will get compiler exception: Unable to resolve symbol: decrease in this context.

Lately I was writing Clojure code that needed to do the POST request to the external service.

Again I get from Patrick Smacchia an opportunity to test new version of *NDepend* - this time version 6.

September has come and as usual at this time of the year I went to Krakow (Poland), to attend DevDay.

It has been almost one year since I've started using Emacs.

Around a year ago, I've started reading about Clojure and in general about Lisp .

Leiningen is de facto standard for creating and managing projects in Clojure.

On the 12 of March I've attended *Wroc# 2015* - a free software developer conference organized by Objectivity company.
