This is a quick guide for newcomers to Svelte who already have a background on a web framework (preferably but not necessarily Vue.js). The reader is therefore expected to have some familiarity with HTML, CSS, and JavaScript.

This is a compact Go reference based on unit testing assertions as opposed to print statements—usually the norm. Comments are kept to a minimum; the reader is assumed to be familiarised with C-style languages (Java, C#, C++, etc.)

This is a project-orientated Vue.js and Bootstrap Vue demonstration. The project is a mobile-first (but also desktop-friendly) Hangman game.

I am an Excel monkey. What do monkeys have to do with pandas? If you are like me and tend to solve all problems that involve data and numerical calculation in Excel, you must have come across a dreaded moment in your life in which you had to decide between cleaning the data from scratch every time there was a change, writing a cryptic nested set of functions, or…. (drum roll) writing a VBA script.

I was thinking about Fermat’s Little Theorem and I wondered whether this primality test could be used to generate prime numbers faster than the Sieve of Eratosthenes, which is typically used to market Haskell to imperative programmers.

The ideal number of columns and whether to use tabs or spaces are frequent topics of debate among programmers. In this post I justify my preference for 70 columns and 2 spaces.

There is nothing more frustrating than spending time dealing with expenses since it is an activity that adds zero value to our customers and contributes nothing to our personal development. In short, doing expenses is an utter waste of time. In this post I show how I automated my expenses using Expensify and Greasemonkey.

In this article we explore the Event Sourcing Pattern and its cousins (Retroactive Event, Parallel Models and Materialised View) using a Haskell model to investigate the implications of implementing said patterns and the challenges that arise from their use. In particular, we note that the Retroactive Pattern is difficult to implement in an efficient manner whenever the possibility of inserting an arbitrary number of “missed” events between existing events is desirable.

The Command and Query Responsibility Segregation (CQRS) Pattern is a solution to the problems that are inherent to the Create, Read, Update and Delete (CRUD) approach to data handling. We use Haskell to explore the problem scope and the proposed solution described by the pattern.

Many people abandon their Vim learning efforts because they fail to become productive quickly enough. The lowest common denominator form of behavioural expectation from a new text editor may be, arguably, embodied by Microsoft Notepad. This article provides a 1:1 mapping of Microsoft Notepad’s functions to Vim so that Vim newcomers can feel quickly at home. Vim-specific bells and whistles are avoided to keep focused on the stated goal.
