It’s been close to two years since I started working with AWS CloudFormation, the Infrastructure as Code solution by and for AWS. With CloudFormation you can describe and provision your entire AWS infrastructure in code. The entire AWS environment I work with is provisioned through CloudFormation - we only have…
“Ah? A small aversion to menial labor?” The doctor cocked an eyebrow. “Understandable, but misplaced. One should treasure those hum-drum tasks that keep the body occupied but leave the mind and heart unfettered.”
My first exposure to programming was on an HP-85 . This must have been around 1992 or 1993; the machine was then already largely obsolete, having been first produced in 1980.

I often don't blog about this kind of stuff. Yesterday I friend of mine showed me this awesome project called cool-retro-term . When yo...
I explain how Compiler Explorer runs on Amazon's cloud computing infrastructure
What does it mean to add versioning to the go command? The overview post gave a preview, but the followup posts focused mainly on underlying details: the import compatibility rule , minimal version selection , and defining go modules . With those better understood, this post examines the details of how versioning…
The Racket GUI library provides an "editor toolkit" which can be used to implement programs that use an interactive graphical canvas where objects can be moved around with the mouse. This toolkit has good reference documentation, however this documentatio...
You’ve implemented some of your performance critical code using the new platform intrinsics API. The code is now running 10x or even 100x faster than before, and you might think that it can’t get any faster. This post will show you some less obvious (but almost universally applicable) techniques for improving the…
I haven’t been on r/lisp for a week or so due to being rather low on free time as we try and get an alpha of our game out of the door. When I did pop back I saw ‘5 Reasons why Lisp Games Suffer and proposed solution’ which I thought would be interesting, but what I found was bizarre and misinforming.
Whenever there is a discussion online about the tools to build software, there is always That One Person that shows up and claims that all b...
Having benefited from “var” for many years when writing c#, I’m delighted that Java is at last getting support for local variable type inference in JDK 10. From JDK 10 instead of saying ArrayList<String> foo = new ArrayList<String>(); we can say var foo = new ArrayList<String>(); and the type of “foo” is inferred as…

About six months ago, I discovered something on my smartphone that horrified me: I went to undelete a file in DiskDigger, and I stumbled upon a plethora of unexpected jpegs: screenshots of my activity. Screenshots that I didn’t take. Screenshots of my conversations. Screenshots of my GPS position. And screenshots of…
I recently attended the Matthias Felleisen Half-Time Show, a symposium held in Boston on 3rd November in celebration of Matthias’s 60th birthday. I was honoured to be able to give a talk ther…
For a long time I was looking for some time to play with Lasp: Lasp is a suite of libraries aimed at providing a comprehensive programming system for planetary scale Elixir and Erlang applications. Ye
Haskell’s State monad has a shameful secret. It’s not a monad [ State monads don’t respect the monad laws in Haskell, Simon Marlow ] . Look:
Briefly put, types in L-world are ambiguous, leading to unhygienic mixtures of value operations with reference operations, and uncontrolled pollution from null s infecting value code.

.NET is a managed runtime, which means that it provides high-level features that ‘manage’ your program for you, from Introduction to the Common Language Runtime (CLR) (written in 2007):
My dad started teaching me Basic when I was about 7 years old, and since about that age I knew that I wanted to build software for a living. It was obviously a fun and useful thing to do, and something that I could do well. But there is a big — and I mean Grand Canyon-scale BIG — difference between “programming” and…
