    No more busywork! DRY up your NSString constants

    Posted on Wednesday 2 July 2014 by george

    Preamble In the last few years, Objective-C has become enormously DRYer. For example: in the past, adding a property to a class meant adding several of: an ivar, a @property, a @synthesize, a getter/setter, and a release call in dealloc. Worse, renaming or deleting the property meant updating all these. This was error-prone busywork, and […]

    Lightweight inline formatting for NSAttributedString

    Posted on Tuesday 11 March 2014 by

    For Cocoa developers: I’ve just put a small category on NSMutableAttributedString on Github. It applies *bold*, /italic/, _underline_, -strikethrough-, ^superscript^ and ~subscript~ styles, and handles */nested/* and *overlapping /styles* properly/.

    Using vDSP_deq22 as a bandpass filter

    Posted on Tuesday 4 February 2014 by George

    For reasons that may become clearer in future, I needed to use a bandpass filter in an iOS app. The DSP part of Apple’s Accelerate framework makes this lightning fast both for the programmer to implement and for the machine to execute … if the programmer knows how use vDSP_deq22, which is documented, at best, […]

    Fixing Bluetooth sleep issues with MacBook and Magic Trackpad

    Posted on Thursday 11 October 2012 by george

    We have an old MacBook (the original white Intel model from 2006) running EyeTV as our telly. Apple’s Magic Trackpad makes a handy remote control for this setup. Unfortunately, Bluetooth on the old MacBook is highly temperamental. Built-in Bluetooth regularly fails: out of the blue, the Mac decides that it has no Bluetooth module after […]

    Plotting and iGraph on Lion and Mountain Lion

    Posted on Thursday 30 August 2012 by robin

    After giving up on Gephi (again, I really should learn), I decided it was time to get to grips with Python and iGraph since I really need to produce multiple iterations of a graph. The matmos at CASA have, of course, been touting Python for ages, but I’ve just not had the time/incentive to install […]
