Remote Admin Incantations
Quick offtopic post... here at Wooji Juice, as well as the various Macs we use for developing and testing, we also have a Mac Mini. It has performed sterling duty as our server for several years now (and hopefully will continue to do so).
The Mini doesn't actually have a keyboard or mouse connected to it: most of the time, it's just sitting there humming away quietly, serving up files, shuffling email around, and so on. It doesn't actually need to be clicked or typed at, and the little admin work I need to do on it, I can usually do via Remote Login (or ssh as it's more commonly known in the Unix world).
iPhone, OpenAL, and IMA4/ADPCM
It's been a while since we've run a technical post here on the blog. I recently ran across a problem that seems to be quite common amongst iPhone game developers, so I thought I'd do a quick post on it: using IMA4 (ADPCM) audio encoding on the iPhone/iPod Touch.
IMA-ADPCM is a compression standard defined by the Interactive Multimedia Association that gets you 4:1 compression on 16-bit audio files. It's supported natively by the iPhone — but only using certain APIs.
