This is part one of a two-part article. Part two is here. A while back somebody told me to check out MiniZinc. Eventually I did and really enjoyed it, so figured I’d write about it here. This is actually going to be a two part article. Right now we’re talking about what it is and how it works, and in the next post…
Describing three strategies of implementing type classes, aiming to clarify their behavior
How to solve linear systems that have many solutions, or those that have no solutions at all? That's the theme for a thick math textbook, of course, but from...
Jupyter presents a unique programming style where the programmer can change her code while it's running, reducing the cost of mistakes and improving the interactivity of the programming process. I discuss the benefits and limitations of this approach along with the related work.
This is the 6th post in the Learning Clojure focus series. In general, one learns by comparing to what one already knows: I’m learning Clojure in that way. Coming from a Java background, I naturally want to use streaming features. So, what would be the Clojure counterparts of Java’s functions filter(), map(), etc.?
In this tutorial, you are going to learn the basics of Vue.js. While we learn, we are going to build a Todo app that will help us to put in practice what we learn.
Resurrecting an old tradition of this blog, let’s take a simple problem, go over a way too long list of alternative solutions, and evaluate their merits. Our simple problem is this: we want t…
Map any 3D point on or above a triangle-subdivided sphere to a triangle index in constant time, without recursion, table lookups or complicated branching logic.
In this brief post I want to discuss a fairly unusual feature of Haskell - functions that can be parameterized by their return type.
Whether or not you believe that the iPad is the future of computing, it does bring a ton of interesting new features and capabilities to the table, especially with the latest release of the Pro version. This week, let’s take a look at how we as third-party developers can take advantage of some of those capabilities to…
Hi guys, in this post we will learn how to bypass downloading restrictions on Soundcloud. We will create a Python script which will allow us to download even…
Update 2022 : TheIronBorn has found even better permutations using a smarter technique. That thread completely eclipses my efforts in this article.
‘Monadic Parsing in Haskell’ is a short paper that laid the groundwork for libraries like Parsec and Attoparsec. Although it was published in 1998 (almost 20 years ago!) it has aged gracefully and the code samples will run with almost no changes. However, the state of the art has advanced since then and I think the…
Updates (2024) Since this post was originally written, the FizzBuzz github repository has received 23 additional contributions so the total…
Here’s a bit of code from Kernighan’s and Ritchie’s seminal text, The C Programming Language . I’m not sure I’d actually recommend coding this way (as written in the book, the entire program has only one comment), but it’s so darn clever and concise, I can’t help but post it. This snippet is part of a larger program…
So far this year I’ve been bitten three times by compiler edge cases in GCC and Clang, each time catching me totally by surprise. Two were caused by historical artifacts, where an ambiguous specification lead to diverging implementations. The third was a compiler optimization being far more clever than I expected…
Let's compare the before/after of React's new context API.
A look at common mistakes in DSL designs and how to fix them
The futex (short for "Fast userspace mutex") mechanism was proposed by Linux contributors from IBM in 2002 [1] ; it was integrated into the kernel in late 2003. The main idea is to enable a more efficient way for userspace code to synchronize multiple threads, with minimal kernel involvement.
This is a short response to the recently announced Go 2 generics draft proposals
Monday’s /r/dailyprogrammer challenge was to write a program to read a recurrence relation definition and, through interpretation, iterate it to some number of terms. It’s given an initial term ( u(0) ) and a sequence of operations, f , to apply to the previous term ( u(n + 1) = f(u(n)) ) to compute the next term…
Optimizing a breadth-first search of an implicit graph for secondary storage, and memory use in general.
Michael Snoyman's personal homepage and blog, featuring writing about programming, open source, health, finance, religion, and whatever else catches his interest.
Nearly all of Go’s distinctive design decisions were aimed at making software engineering simpler and easier. We’ve said this often. The canonical reference is Rob Pike’s 2012 article, “ Go at Google: Language Design in the Service of Software Engineering .” But what is software engineering?
