sgx error (background gpu access not permitted)

Published October 1, 2010 by doug

I recently started seeing this error in my Cocos 2d iPhone application running on iOS 4.1:

sgx error (background gpu access not permitted):
Program received signal: “SIGABRT”.

After searching around, I found this thread on the cocos2d forum.

I modified my code in the ApplicationDelegate to look like:


– (void)applicationDidEnterBackground:(UIApplication *)application
{
[[CCDirector sharedDirector] stopAnimation];
}

– (void)applicationWillEnterForeground:(UIApplication *)application
{
[[CCDirector sharedDirector] startAnimation];
}

– (void)applicationWillResignActive:(UIApplication *)application
{
[[CCDirector sharedDirector] pause];
}

– (void)applicationDidBecomeActive:(UIApplication *)application
{
[[CCDirector sharedDirector] resume];
}

This solved my problem. I hope it helps someone else.

iTerm crashing on launch

Published April 10, 2010 by doug

I’ve recently been using iTerm on the Mac. I was happily using it, until it started crashing on launch. After searching around on the internet, I finally figure out what is wrong. The issue occurred because I was using an external display. When not connected to the external display the app would crash.

I found details in this bug here: http://sourceforge.net/tracker/index.php?func=detail&aid=2889711&group_id=67789&atid=518973

There are 2 easy ways to solve this problem.

1. In the normal terminal type:

defaults delete net.sourceforge.iTerm "NSWindow Frame iTerm Window 0"

2. Open ~/Library/Preferences/net.sourceforge.iTerm.plist and removed the following entry:
NSWindow Frame iTerm Window 0:

Buying an Apple Product

Published March 3, 2010 by doug

Apple is very secretive about it’s products and releases. This makes it very difficult to know if it’s a good time to buy a particular Apple product.

To aid you in your decision, Macrumors.com has a Buyer’s Guide. This guide lists the release history of each product and gives a recommendation as to if now is a good time to buy or not.

If you’re looking to buy a new mac, iphone, monitor, etc.. this guide should be your first stop.
