For those of you who have been wondering about what Apple’s mystery WWDC Science Coding Project will be, I am now able to spill the beans. I’m sure some have already connected the dots, but for those who haven’t figured it out yet, Apple’s WWDC code-a-thon is centered around the new open source Core Plot framework.
The Core Plot project began back in January after a post I made here on MacResearch as a ‘call to arms’ to build a decent open source plotting alternative for Apple systems. There are some options already available, such as SM2DGraphView and my own Narrative framework, but these are getting long in the tooth and are reasonably basic. There is also the very capable DataGraph framework, which is a commercial offering, but one drawback of all of these solutions is that they were developed before the iPhone, and do not support what has become a very important platform for developers.

Without plugin support (read: Flash), a preference screen, or any semblance of stability, this super-early, unsanctioned build of Chrome for OS X is by no means ready for daily use. It’s good to see that it works, though—and now we know that the planned fall beta is at least plausible. [Manu-J via TUAW]

Enable SpeedStep support on any capable Intel CPU: “As described on Wikipedia, SpeedStep ‘is a trademark for a series of dynamic frequency scaling technologies (including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat dissipation.’
Apple implements SpeedStep on certain Macs, but not all of them (and if you’ve built your own Mac, you may not have any SpeedStep support). Here’s how to enable SpeedStep on any Mac: Use the xnu speedstep kernel extension. Just download IntelEnhancedSpeedStep.kext.1.4.5.zip, then copy IntelEnhancedSpeedStep.kext into /System/Library/Extensions. Don`t forget to repair permission (in Disk Utility) when done, then reboot your…

TUAW Bookshelf: iPhone in Action: “
Filed under: Analysis / Opinion, iPhone, iPod touch, TUAW Bookshelf
I’ve never found book reviews to be terribly helpful — technical book reviews even less so, as how one learns differs from person to person. Some iPhone devs out there learned simply by poring over Apple’s copious documentation. Others have been poking at the iPhone’s innards since pre-SDK days, learning as they went from forums and good old hacking. But once the NDA lifted, the floodgates of iPhone dev books opened.
Each book and each publisher has a different angle both in content and presentation. Each book may appeal to different people and different learning styles with different backgrounds (not to mention the numerous sites, blogs and video resources out there beyond what Apple provides). Over the course of 2009 we’ll be taking a look at some books in a new series called TUAW Bookshelf. We won’t just be covering developer resources, either. There’s a wide world of Apple-related reading out there, so stay tuned as we pull from our personal libraries and share our thoughts on what’s available.
To kick things off I read iPhone in Action by Christopher Allen and Shannon Appelcline, published by Manning. I wound up reading this first because one of the authors threw a few copies at me while at Macworld (sorry, I don’t know who you are and I can’t seem to find your business card!). We’ve got a few to give away, but look for that in another post this month.
iPhone in Action is designed to be a soup-to-nuts intro to almost everything you can develop for the iPhone. This includes web apps, which was the book’s main focus until the SDK was announced while they were writing. I don’t think shifting focus to the SDK is a bad thing, and as near as I can tell it didn’t hurt the content. In fact, I thought this book would make an excellent primer to Apple’s mobile platform efforts. Having taught technology for six years, I can say this is the book I’d use for a 100-level course in developing for the iPhone. I’m not saying it will make you into an expert overnight, and I’m not saying you can’t come to the table with zero dev experience, but as a starting point, it is wonderful. To find out why, keep reading…

Sync Your iPhone in Linux—Version 2.0 [Linux]: “
Apple’s 2.0 firmware update generally killed wireless syncing with Linux. Ubuntu users, hackers that they are, have posted a detailed walkthrough detailing a work-around or two that re-connect the two. Thanks Salvador!

The OS X Kernel is Open Source: “I think people either don’t know this or forget about it, but the OS X kernel environment is open source, which obviously is the core of the iPhone OS as well. It doesn’t include all of the stuff at the GUI layer, but there is a ton of code in there that is generally kept in sync with current consumer product releases…”
