Working with the Clinton State Dept Email Dumps in R, Part 1
This isn’t a post about politics. I do have opinions about the now infamous e-mail server (which will no doubt come out here), but when the WSJ folks made it possible to search the Clinton email releases I though it would be fun to get the data into R to show how well the igraph and ggnetwork packages could work…

Cheap BlueTooth Buttons and Linux
Selfie sticks - like most modern inventions - are utter tosh. But they've rapidly brought down the price of Bluetooth buttons. So who am I to complain? Let's take the venerable AB Shutter 3 - You can find it on Amazon for around £2 including postage - or around $2 on AliExpress. Frankly, that's stupidly cheap. OK…

cgo is not Go
Some people, when confronted with a problem, think “I know, I’ll use cgo.” Now they have two problems.

Why GNU Emacs?
I don’t usually try to explain tools that I use to other people, unless they made an explicit request as to how they could improve their workflow. However, since today is “I love Free Software” Day I think I should seize this opportunity and explain what draws me to GNU Emacs and how I use it.

Before You Get Too Excited About That GitHub Study
Another day, another study purporting to find that Tech Is Sexist. Since it’s showing up here, you probably already guessed how this is going to end. Most of this analysis is not original to …

Why Rust's ownership/borrowing is hard
Working with pure functions is simple: you pass arguments, you get a result — no side effects happen. If, on the other hand, a function does have side effects, like mutating its arguments or global objects, it's harder to reason about. But we've got used to those too: if you see something like player.set_speed(5) you…

Friction Between Programming Professionals and Beginners
In this article I want to talk about negative aspects of the programming community, regarding beginner programmers. This is a touchy topic. I will try to explain both sides to the best of my ability, but I’m not endorsing either side. My only hope is that some readers will gain more empathy for the people they are…

Kill Your Dependencies
This post talks about Ruby but it’s true of every language community: Python, JavaScript, Java, etc. The scourge of dependencies spares no one. This is a dependency visualization of every Rails app I’ve ever used. Does any of this sound familiar: Gemfile with 100s of entries. Test gems loading in production. Each…

The Evolution of a Haskell Programmer (2001)
Some time later, I came across Iavor’s "jokes" page, including a funny bit called “ The Evolution of a Programmer ” in which the traditional imperative "Hello, world" program is developed through several variations, from simple beginnings to a ridiculously complex extreme. A moment’s thought turned up the factorial…

How to do distributed locking
As part of the research for my book , I came across an algorithm called Redlock on the Redis website. The algorithm claims to implement fault-tolerant distributed locks (or rather, leases [1]) on top of Redis, and the page asks for feedback from people who are into distributed systems. The algorithm instinctively set…
