An alternative interface for filtering on the iPhone
I’m developing a new iPhone application. Part of the application needs a “filter a list of things” view. I’ve been looking at Apple’s approach for inspiration, most notably the Contacts application. I’ve come to the conclusion that the Contacts approach absolutely sucks, and so I’ve developed my own custom interface instead. This article describes the […]

Stripping out a set of characters from an...
Cocoa’s NSString doesn’t have great support for search and replace at the best of times. But the absence of the NSPredicate class from the iPhone SDK means that there is no quick way to strip a whole range of characters out of an NSString in one go on the iPhone. This article shows one way to do so. Control […]

As part of an iPhone SDK project, I have an sqlite database with a table full of geographic locations, each stored as a latitude and longitude value in degrees.

Range.intersectsNode, Mozilla and WebKit

WordPress plugin to clean up pasted Word content
The basic installation of WordPress 2.5.1 doesn’t enable the “clean up Word content” options of its WYSIWYG editor, TinyMCE, by default. This means that if you copy some content from Microsoft Word, it is not cleaned up when it is pasted into WordPress.

Audio crackles and dropouts caused by Airport Extreme...
I’ve been experiencing an annoying problem recently on my MacBook Pro running Mac OS 10.4.11. Any audio played in my DJ application, DJ-1800 v3.0.2, with Pitch Lock turned on, had constant crackles and pops, and was pretty much unusable. Even with Pitch Lock turned off, the crackles were still there if several tracks were played at […]

I’ve run some extensive tests this morning on a test install of SharePoint 2007, to find out how the default Document Properties in Office documents are used in the default SharePoint 2007 SearchCenter search results. I had been unable to find useful documentation about what is and isn’t indexed and reported, so these are my […]
