It seems like @burritojustice's Islands of San Francisco map is flying around the 'net. I just saw a retweet from Mike Jurewitz (aka @jury) that referenced it unsourced. While his map is far more beautiful and informative, he credits me with inspiring him by producing a map I titled "Seattle on a Sheet." I made … Continue reading Seattle on a Sheet →

I've uploaded my proposal for Objective-C namespaces to GitHub: https://github.com/kylesluder/objc-namespaces That will make it easier to track revisions and collate suggestions. If I ever have the time to work on a proof of concept implementation, I'd like to also add it to that repository.

Every three months I'm forced to change my Apple ID password. This means remembering to update every single iCloud-capable device I own (currently six and growing); if I don't, my shared info like calendars gets out of sync and I, being the forgetful person I am, miss events and information. On top of that, the … Continue reading My Email to Developer Programs regarding mandatory Apple ID password change →

So WWDC 2012 was announced at early o' clock and sold out in less than two hours. New restrictions on multiple purchases didn't do anything to stave the ever-shortening window. As compensation for all the interested developers who won't get to go to WWDC this year, Apple has promised to quickly post the session videos … Continue reading WWDC of the Future →

Adding namespaces to Objective-C is a non-trivial problem. This proposal is a working draft; it may have bugs. (In particular, the definition of @namespace blocks and the @using directive is incomplete, but it's analogous enough to other languages that the intent should be obvious.) This draft will certainly need updates; I welcome comments at optshiftk … Continue reading Draft Proposal for Namespaces in Objective-C →

Last Thursday I gave a talk at Seattle Xcoders titled "iCloud: Lessons Learned." I'm very grateful for the warm reception and the stunning turnout—there were over 40 attendees, many of whom asked some very good questions. By request, I have uploaded my slides. Hopefully they will be useful. If anyone happened to take video of … Continue reading Slides Available from “iCloud: Lessons Learned” Talk at Seattle Xcoders →

**Update:** I just re-read a cocoa-dev post from last month in which Kevin Perry from Apple states the following: > I don't see the nested uses of performSynchronousFileAccessUsingBlock: you mentioned in that code, but that's not a problem anyway, since file access is recursive, as long as it happens synchronously within the outer-most file access block (a fact that admittedly may not be documented well anywhere). That would certainly change things. Perhaps the reason that -relinquishPresentedItemToWriter: was deadlocking on me is because it calls -performActivityWithSynchronousWaiting:, not just -performSynchronousFileAccess? I'll have to experiment. * * * **Now that iCloud** is out, I can finally talk about this in a public forum. Unfortunately, the cocoa-dev mailing list is down. But I really need to get this question out there, or at least written down, because it involves one of the most confusing new APIs in Lion: -[NSDocument performSynchronousFileAccess:] (or -performAsynchronousFileAccess: if you really hate your sanity).

I noticed that the Resource Programming Guide has been updated for ARC, which prompted me to investigate something that has puzzled me for a long time: how does NSWindowController interact with NSWindow's "convenience" method -isReleasedWhenClosed? It turns out that NSWindowController actually calls -setReleasedWhenClosed:NO on its window as part of -setWindow:. It doesn't matter if NSWindowController … Continue reading NSWindowController and -[NSWindow isReleasedWhenClosed] →

After the President finished his speech announcing the death of Osama bin Laden, I bitched on Twitter about his citation of the Pledge of Allegiance, including the Cold War-era addition of “under God.” And I got a small bit of blowback for it. Rather than continue the complaint in 140-character pieces, I figured I’d do … Continue reading Why I Complained About “Under God” →
