Eller's algorithm creates 'perfect' mazes, having only a single path between any two cells, one row at a time. The algorithm itself is incredibly fast, and far more memory efficient than other popular algorithms (such as Prim's and Kruskal's) requiring storage proportional to only a single row. This makes it possible…
I have developed some interest in the Rust programming language. Rust is a systems programming language which means it gets out of the way of developers interested in reaching low-level internals of a system. What sets it aside from other systems languages though is: Borrow checking to guarantee memory safety…
Image differentiation in three languages
Edit (2019-04-09): A quick qualifier for future readers. This post talks about correctness in the sense of correct code and not formal proofs or formal specifications. I refer to correctness in the sense of avoidable runtime errors.
The core playlist in VLC was started a long time ago . Since then, it has grown to handle too many different things, to the point it became a kind of god object .
I've just finished the final rewrite of my website. I'm not lying: this is the last time I'm ever going to do it. This website has gone through countless rewrites – from WordPress to Jekyll to multiple static site generators of my own – but this is the final one. I know so, because I've found the ultimate method for…
In this tutorial, we are going to learn how to draw charts with Chart.js and how to customize them to suit our needs.
I spent some more time with Python and started to realize that I needed something more. Here's a brief list of the reasons why I switched to Clojure.
My latest site redesign and why I left out Sass and media queries in favour of native CSS grid, calc, viewport units and custom properties.}
Inspired by the strangler figs in Australia, a strangler fig application gradually draws behavior out of its host legacy application
Visualization has always been challenging task but with the advent of dataframe plot() function it is quite easy to create decent looking plots with your dataframe, The **plot** method on Series and DataFrame is just a simple wrapper around Matplotlib plt.plot() and you really don’t have to write those long matplotlib…
Basalt is system for graphic design that allows a designer to think in terms of relationships between objects, and it makes it easy to build and reuse abstractions.
It's been a very long time since the last post. So there have come up questions about the Erlang Rationale. I wrote this over 10 years ag...
I’ve been helping a friend understand dynamic programming (DP for short), so I’ve been on the lookout for good resources. The topic is covered all across the web, but I found many of them focused on the code, and not enough on the beautiful visualizations that shed light into how DP works.
Derek Sivers official site. Thoughts on philosophy, culture, self-improvement. Author of Useful Not True, How to Live, Hell Yeah or No, Anything You Want.
I am currently working my way through Higher-Order Perl , a highly recommended tome on effective and practical use of functional programming techniques in Perl. As you’d expect from a book that spends a lot of time discussing such concepts as function composition and recursion, the subject of tree traversal makes a…
Apropos of nothing, I'd like to tell you a tale. It's not an original tale, but it's one of my favorites.
The purpose of this article is to show you step-by-step examples of how to use the Fourier transform algorithm to multiply two numbers. The primary advantage of using fourier transforms to multiply numbers is that you can use the asymptotically much faster 'Fast Fourier Transform algorithm', to achieve better…
There are so many programming books out there, sometimes it's hard to know what books are best. You won't find cracking the coding interview, the pragmatic programmer, or even the best python book. These are the best programming books curated from each major Software field.
Our seventh-grade class was led into a room full of brand-new Macintosh Performas . The day's lesson was a crash course in the use of an uncomplicated yet marvelous program. With it, one might persuade a computer to do anything and everything - or so it seemed to a child with the attention span to appreciate the…
After diving into the C language through K&R, and then studying portability (see C Portability Lessons from Weird Machines ), my next challenge was to take a systematic look at the standard library. To do this I worked through P. J. Plauger’s book The Standard C Library (ISBN 978-0131315099) where he examines an…
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
