A simple core.async job system in Clojure
In my off time (and my on time, for that matter) I've been working on this quirky thing I've called Scinamalink (sounds like 'skinamarink'). Scinamalink lets customers send Magic login links to their users with a single REST API call. If you don't know what a magic

Open source Rails apps to study and learn from
If, like me, you learn best by studying other code here's five some open-source rails apps with something to teach. They're a great resource to study and improve your own code, or to use as the starting point for your own applications. All of these applications use Rails 2 but as they are open-source they are a great…

How does your programming language handle “minus zero” (-0.0)?
The ubiquitous IEEE floating-point standard defines two numbers to represent zero, the positive and the negative zeros. You also have the positive and negative infinity. If you compute the inverse of the positive zero, you get the positive infinity. If you compute the inverse of the negative zero, you get the negative…

Useful and useless code comments

Programming without objects
Recently I gave an itemis internal talk about basic functional programming (FP) concepts. Towards the end I made a claim that objects and their blueprints (a.k.a. classes) have severe downsides and that it is much better to "leave data alone", which is exactly how Clojure and Haskell treat this subject.

C# strings silently kill your SQL Server indexes in Dapper
If you're using Dapper with anonymous objects to query varchar columns, you're probably sending nvarchar(4000) parameters — causing CONVERT_IMPLICIT on every row and defeating your indexes. Here's the fix.

C++ Has Become More Pythonic (2014)
C++ has changed a lot in recent years. The last two revisions, C++11 and C++14, introduce so many new features that, in the words of Bjarne Stroustrup, “It feels like a new …

The problematic culture of “Worse is Better”
Our industry has been infected by a dangerous meme, and it’s one that hasn’t been given its proper scrutiny. Like many memes that explode in popularity, “Worse is Better” gave a name to an underlying fragment of culture or philosophy that had been incubating for some time. I point to C++ as one of the first instances…

Why Lisp Will Never Win (2003)
For 2003 OSCON I proposed to give nine five-minute talks in a 45-minute slot. To avoid confusing this with the real lightning talks sessions, Nat decided to call my talk ``Nine Views of Mark Jason Dominus''. At first I didn't like that title, which sounded too much like self-promotion. But I warmed up to it after a…
