Sleepwatcher for Mac OS X - 0 views

shared by Jeff Johnson on 06 May 09 - Cached
  •  
    SleepWatcher is a command line tool (daemon) for Mac OS X that monitors sleep, wakeup and idleness of a Mac. It can be used to execute a Unix command when the Mac or the display of the Mac goes to sleep mode or wakes up or after a given time without user interaction. It also can send the Mac to sleep mode or retrieve the time since last user activity. A StartupItem, sample start and sleep scripts and the source code for sleepwatcher are included in the download. A little bit knowledge of the Unix command line is required to benefit from this software. SleepWatcher is published under the GNU General Public License.

airport - the Little Known Command Line Wireless Utility - OS X Daily - 0 views

  •  
    Strangely hidden from the casual user is a spiffy command line utility that allows you to view, configure, and troubleshoot your Mac's wireless connection. It doesn't appear to be well documented, and judging by the obscure location of the command, Apple probably didn't think it would be too useful for the average Mac user. But the hidden command line airport tool is very useful indeed, so here is how to access it, and how you can use it too. The first thing you'll want to do is create a symbolic link to the airport command, because it is situated in a very inconvenient location for quick usage.

Image cleanup script « Managing OS X - 0 views

  •  
    Here's a cleaned-up version of the script I use, with site-specific stuff removed for the most part. If you use this, you'll need to modify the paths to any local user home directories for any local users you have on your image. There are generic examples for a local admin user named "admin" and the root user (which if you never login as root, you shouldn't have to clean up!)

Mac vs. PC: What You Don't Get for $699 - BusinessWeek - 0 views

  •  
    Now Microsoft is fighting back with its own advertising campaign. I've enjoyed some of its elements. The Seinfeld spots were weird. I was intrigued by some of the "I'm a PC" spots that aired last fall, depicting PC users engaged in a variety of jobs-teaching law, protecting endangered species, blogging for Barack Obama. The message: You can use a Windows PC and still do cool and interesting things. Not bad. Then came the adorable little girls: Kylie, age 4, and Alexa, age 7, e-mailing pictures of fish and stitching together pictures of a fort into one. Microsoft, it seemed, had finally found its advertising voice.

Randomizing the Mac OS X Software Update Server | Krypted - 0 views

  •  
    I've had a few instances where there was no way to setup round robin DNS or a load balancer and we were looking to alternate between a bunch of software update servers.  In order to do so, I've written a quick shell script to do so.  Here it is, in pieces, so it makes sense.

Tweetie for Mac (atebits) - 0 views

  •  
    Double click on a tweet to view not only that tweet, but the entire conversation history leading up to that tweet. Never lose track of a conversation again. Independent compose windows stay out of your way until you need them. Have as many open at a time as you'd like while you compose your thoughts. Everything has a keyboard shortcut, (Command-Enter will send a tweet).

10 iPhone Apps for IT Administrators - 0 views

  •  
    Apple's iPhone Apps have seen a nearly exponential rate of proliferation since the launch of the App Store in July 2008, with many of the smartphone applications aimed at helping users with small, routine tasks (or procrastinate with several games of Pong). Big-name companies such as Google, Salesforce.com and Oracle have all created software designed to let users engage with their products even while on the road.

Spanning Tree Protocol: AppleTalk and NetInfo Issues - 0 views

  •  
    When the Spanning Tree Protocol is enabled on an Ethernet bridge or switch port to which a Macintosh computer is directly connected the computer may be unable to use AppleTalk or NetInfo services. Appletalk issues observed range from no AppleTalk services, local (to this specific network) AppleTalk services, degraded performance, and intermittent network services. If the Spanning Tree protocol is enabled on the port to which a Macintosh computer is connected packets necessary for AppleTalk address assignment and network discovery can be dropped by the switch. This causes the Macintosh to acquire invalid or incomplete network information resulting in the behavior discussed above.

Bugs & Fixes: A potentially risky Finder permissions command | Mac OS X | Mac 911 | Mac... - 0 views

  •  
    Suppose you want to change the permissions settings of most or all the items in a given folder. Perhaps you want to modify permissions so you can access the content of files you would normally be prevented from editing. Or perhaps the permissions of your own files have somehow gotten messed up so that you can no longer copy or move them.
