When defragmenting a file with snfsdefrag on systems running OS X Mountain Lion v10.8.4 and earlier, an invisible "__defragtmp" file may be created which cannot be deleted.
This issue may occur when the following are true:

The defragmented file's name contains precomposed Unicode characters, such as letters with diacritical marks (an accent, grave, or umlaut).
snfsdefrag is run by root.
snfsdefrag is run when the current working directory is on an Xsan volume, or snfsdefrag's recursive option (-r) is used.

iOS 6 introduced Do Not Disturb, but some of us were annoyed by its implementation: Though the feature silenced iOS notification sounds while your iPhone or iPad were sleeping, those noises still blasted out when the device was in use. If that's not what you want to have happen, iOS 7 has the solution.

Armed with this hint, Do Not Disturb will empower you to use your iOS device in a room with sleeping people, or in a meeting where you're supposed to be paying attention, without fear that a bleep or bloop will bother those around you.

Head over to the Settings app, and tap on Do Not Disturb. Scroll down to the bottom of the screen, and set Silence to Always, instead of Only While iPhone Is Locked. From now on, Do Not Disturb works regardless of whether your iPhone is awake and in use, whenever the mode is enabled.

You can use OS X Recovery to erase your computer using Disk Utility and then reinstall OS X. 

iOS 7's new design seemed to cause some spacing issues in Messages, especially on the iPhone. Where you formerly could see the full names of the people you texted, iOS 7 shows only a first name, or perhaps a first name and last initial. When you know as many Dans as I do—even as many Dan M.'s as I do—that just won't do.

There's a fix, though the setting isn't where you might expect.

In the Settings app, tap on Mail, Contacts, Calendars. and then scroll way down to the Contacts section. Under that header, tap on Short Name. For my purposes, I turned off both Short Name and Prefer Nicknames. Now, Messages shows the full names of the contacts I'm sending messages to, shortening the button labels at the top as necessary to make everything fit.

The terminal-notifier command is a tool used for sending messages and actions to the Notification Center. It’s a gem, so to set it up we’ll first run the gem command to install it by name:

gem install terminal-notifier

Once installed, run the command along with the -message option followed by a quoted message:

terminal-notifier -message "Hello world"

This produces a message from Notification Center as follows:

The title on the screen though, says Terminal. We want to change the title to something else. To do so, add the -title option. Adding the -title option along with a quoted title then displays a title in the top of the notification.

You can also add a subtitle, which allows for you to, for example, add the name of the app in either of the two fields along with the action you’re performing in the other. For example, if you...

Most of my readers have already upgraded from iOS 6 to iOS 7. But, you might need to write some technical documentation on how to do so for your end users. If you find yourself in such a situation, you can just cut-copy-paste this article into your own documentation.

Preflight

First, backup the device. When I did this upgrade I was flying without a net and didn’t bother to back the device I was upgrading up. Having said that, I also don’t keep any data on my device, so I would strongly recommend backing up before you do your upgrade if you do have content you want to make sure your preserve. The upgrade doesn’t erase your data; however, whenever you’re doing a major update, it’s a good idea to backup (it’s also a good idea to backup when you’re not doing a major update). If you need to backup, check out this article on manually backing up with iTunes.

Most will also want to go ahead and update to iTunes...

Another day in Göteborg brought many more fascinating talks, including the first public talk on autopkg.

For those using JAMF Casper, Marko Jung from the University of Oxford showed how by adding many modules to Self Service, users have been empowered to do many tasks with the click of a button which would normally require a help desk call.  This implementation has led to happier users, and looks like a great way for organizations to reduce common calls.

Daniel Svensson from IKEA gave a very interesting talk about scaling Mac management over hundreds of sites, each with relatively few clients.  Particularly interesting in IKEA’s deployment is the use of existing Linux infrastructure to support NetBoot and update caching, instead of having to deploy separate hardware to each store.  By using the existing Linux servers which are part of the baseline deployment for each store, Mac support comes automatically with each store.  Also interesting is how replication occurs...

Some car stereos and accessories that use Bluetooth for control and playback may require a firmware update to work as expected with the AVRCP 1.4 support added in iOS 6.
Symptoms may include:

You can't control playback through Bluetooth.
Song name, artist, and other information doesn't appear on the car stereo.

This document describes the security content of iOS 7.

Can I skip Songs?
Yes. You can skip six songs per station per hour. If the Skip Forward control appears dimmed and doesn't respond, you have reached the maximum number of skips for that channel per hour.
Can I repeat or replay a song?
Similar to a radio station, a song on iTunes Radio is played in real time. You can purchase songs you like directly from the station's history.
How do I fast-forward a song?
Similar to a radio station, a song on iTunes Radio is played in real time; however, with iTunes Radio, you can skip up to six songs per hour on a station.
Why does the music stop playing after two hours?
iTunes Radio will time out if you don't interact with your system or device for approximately two hours. If this happens, simply access iTunes Radio again and choose a station to continue playing.
How do I remove ads from iTunes Radio?
A subscription to iTunes Match will provide the added benefit of ad-free iTunes Radio.
