Salty language

Ever need to sound really salty?  The Eagle's seamanship manual is on Google!

Never forget that when a squall approaches, it is prudent to fake out the spanker.

NSLog with the current selector, __LINE__, __FILE__

This is a handy bit of code I sprinkle in as a quick debug printf:
#define NSLogHereIAm() NSLog(@"got selector %@ at line %d, file %s", \ NSStringFromSelector(_cmd), __LINE__, __FILE__)
Just put it in wherever you want to see that your code executed:
int x = 3; NSLogHereIAm(); [foo bar];

iPhone class at the junior college across the bay

Stanford's iPhone programming class - keep hearing it's useful, but haven't checked it out myself yet.

http://www.se-radio.net/ is my current favorite for technical podcasts.

Cocoa things I can never remember

• UIView frame:

In superview coordinates. Changing this moves the view but doesn't redraw.

• UIView bounds:

From 0,0. It's the size of the view.

• The indicators on things like voicemail (to tell you you have N voicemails) are badges. Set them with the badgeValue property.

• Nib files - most objects are going to get an initWithCoder: message when they're instantiated. See the Resource Programming Guide, The Nib Object Life Cycle.

• Creating preference files

Setting up Twinkle and asterisk on the same machine

If you want to use Twinkle on the same machine as your asterisk instance, you'll need to change the SIP port that Twinkle uses. Assuming asterisk is up an running, you'll get this error message when you start Twinkle: Failed to create a UDP socket (SIP) on port 5060 Address already in use Hit "System Settings" on this screen: And then choose network: Change the SIP port to 5061 and it'll start up and connect to your local asterisk instance.

Moving from Mephisto to Blogspot

I thought I needed to move my old blog from Mephisto to here.

It looks like the way to do it would be to go via WordPress using this tool, and then to Blogspot using this.

Eventually I'll get around to making that happen. But when I was going through my old posts, I realized that most of what was there dated fairly quickly. I'll probably just move over a couple posts by hand and not worry about the others.
