Two weeks at LShift

On a welcome break from studying for my GCSEs at school I spent two weeks doing ‘work experience’ at LShift. At the end of the two week placement I was interrogated by Keith Fisher. Here’s a transcript: 1. Did you have a choice in where to do your work experience placement? Yes I had complete…

When in Rome

I’ve been trying to integrate js-sequence-diagrams into Trac. I’ve reached the point where I can choose between my sequence diagrams getting rendered, and the rest of the Javascript in Trac working. And it’s all because of an underscore… There’s a popular library in the Javascript world: underscore. In python _ is used to internationalize a…

Getting back into front-end web development

I’ve been working on a small SPA (Single Page Application) – just HTML, CSS and JavaScript statically served and doing its thing entirely in the browser. I learned a great deal throughout the project, but here are some of the things that strike me as most valuable. Get a good workflow going I used Grunt…

Two Magnolias, one container

We are using Magnolia in a number of projects here at LShift. I have been feeling that Magnolia has a simple way to do most things, but often there are a number of other plausible alternatives that gradually lead you into wasting enormous amounts of time. Here I want to present a simple way to…

Predicting and controlling correlations in differentials of addition mod 2^{n}

This is a paper I wrote in collaboration with Scott Fluhrer in 2005. It was not accepted for FSE 2006; it would have been better if I hadn’t waited until 2014 to make it public, but better late than never.

Cards on the table: I like Scala. Right now it’s my go-to general purpose programming language, but I know that many people have a dim opinion of it, or appreciate its positives but are heavily conflicted by its negatives.

Facebook android security fail

I wrote about the Ocado android applications ridiculous privileges  list a while back. Facebook has reminded me of it: Facebook app now reads your smartphone’s text messages? THE TRUTH.

UX design in Agile projects

We’ve been making a habit of collaboration with partners for what seems like forever, so why is it that we find it hard to get the formula right with front-end designers? Are we a particularly fussy bunch, or is there something more systematic going on? Recently we’ve been working with the Agile Research Network who were…

Grunt uglify file specs

I struggled a bit finding relevant examples of Gruntfile configuration for Uglify, so having solved a few specific problems myself, here’s what I came up with. This is just a snippet from the whole Gruntfile of course, and contains half-decent comments already, though I’ll provide some extra explanations below to point out the most interesting…

Getting Sieves Right

The great thing about being wrong is that you get to learn something. In a previous post I went on at length about the the sieve of eratosthenes. Now that I have been enlightened by Melissa O'Neill I must make corrections.
