Fortunately it’s pretty easy to reinitialise the Kerberos database on a Mac – simply follow these steps:

In the Utilities folder, open Keychain Access. In the System keychain, find and delete the three com.apple.kerberos.kdc entries – a certificate and a public/private key pair generated from that certificate.

1. In Terminal, run ‘sudo rm -fr /var/db/krb5kdc’ – this will destroy the local KDC database.
2. In Terminal, run ‘sudo /usr/libexec/configureLocalKDC’ – this will regenerate the local KDC database, including a new certificate and SHA1 hash.
3. Bind the machine to OD.

Once they’ve constructed an entire holodeck, perhaps the point will be moot, but Microsoft Research is presently working on some pretty clever 3D holograms, too. By combining the age-old optical illusion of the mirascope toy with a modern light field display, a team of researchers have managed to make a moving 3D image float in midair at 15 frames per second, emulating 192 different viewpoints at a time.

Typically, such light field displays have to be demonstrated under glass, away from curious fingers, to maintain their effect, but you can reach right out and “touch” these images with the aid of a depth tracking camera like Microsoft’s Kinect. The team’s calling the project Vermeer, and while the first revision actually use a Kinect…

Fraser Speirs, “Misconceptions About iOS Multitasking”:

There is one iOS “tip” that I keep hearing and it is wrong. Worse,
I keep hearing it from supposedly authoritative sources. I have
even heard it from the lips of Apple “Geniuses” in stores.

Here is the advice – and remember it is wrong:

All those apps in the multitasking bar on your iOS device are
currently active and slowing it down, filling the device’s memory
or using up your battery. To maximise performance and battery
life, you should kill them all manually.

Wrong. Wrong. Wrong. Wrong. Wrong. Wrong. Wrong. There are caveats
to this but anyone dispensing the advice above is clearly
uninformed enough that they will certainly not be aware of these
subtleties.

Fraser provides a great layman’s explanation of why this is wrong. Bookmark his post, show it to anyone who claims otherwise.

Bottom line: the iOS multitasking bar is not like the command tab switcher on Mac or Windows. It is not a list of currently “running” applications. It is simply a list of your most recently used applications, whether they’re running in the background, suspended in memory, or completely inactive. Notice, for example, that if you turn an iOS device off and on, completely restarting the device, the multitasking tray still shows the same apps. It’s like your browser history.

Emptying this list of applications is simply needless, mindless, busywork. It was absolutely never intended to be used this way and anyone who does this is just wasting their time. The system suspends apps running in the background automatically. The system removes suspended apps from memory automatically, when needed. Manually zapping all apps from this list is a voodoo placebo. The whole point of iOS’s multitasking model is that you, the user, should not have to worry about managing which applications are running and which are not. If you were supposed to do that, apps would have a Quit command. They don’t. You just go home, and the system should take care of the rest.

The worst thing about this story is that the advice is repeatedly coming from the people working at the Genius Bar in Apple stores. There was a discussion about this on Twitter over the holidays and I received a bunch of comments from readers who’ve been given this same “advice” when they’ve taken their iPhones to the Genius Bar to diagnose some actual problem.

Like with any voodoo, there are die-hard believers. I’m quite certain that I am going to receive email from people who will swear up-and-down that emptying this list of used applications every hour or so keeps their iPhone running better than it would otherwise. Nonsense.

As Fraser mentions, yes, there are exceptional situations where an app with background privileges can get stuck, and you need to kill that app. The argument here is not that you should never have to kill any app using the multitasking switcher — the argument is that you don’t need to do it on a regular basis, and you’re not making anything “better” by clearing the list. Shame on the “geniuses” who are peddling this advice.

Did you think that quantum physics is complicated? Try the quantum theory of pixels, as explained by 8-bit Professor Hawking.
It may help you understand the former or make your brain explode forever but, if you are a nerd, it will make you smile. Read the whole cartoon at [Bouletcorp via Comics Alliance] …

One thing they wanted to be able to do was to use the Product Downloads for hosting attachments for individual products, for example, a PDF info sheet. The built-in functionality of WP e-Commerce however is to only display the product downloads links once someone has purchased an item and gone through the checkout process.

I found a guide on bloke.org showing how to do it in 3.7, but in version 3.8 they changed the way that the product downloads were stored and the old way no longer worked.

After much head-scratching, I arrived at the following solution:

$args = array( 'post_type' => 'wpsc-product-file', 'numberposts' => -1, 'post_parent' => $post->ID );

$attachments = get_children($args);

if ($attachments) {

    foreach ( $attachments as $attachment ) {

        echo "<a href=", $attachment->guid, ">$attachment->post_title</a>";

    }

}

This is a very simple, quick method to make everyone have beautiful skin in these holidays family photos. I’ve used a variant of this method in the past years and it works perfectly.
It does work great because it will soften the skin but would leave enough texture to make the person look natural. And it’s simple and quick enough to apply it easily to several photos. [Two Cities Photogr …

Aside from the fact that the current Apple Remote Desktop Installer requires 10.6 and doesn’t want to run in 10.7 one of the more vexing aspects of working with ARD is that eventually one becomes heavily invested in the library it creates and setting up a new installation or moving a library to another machine is problematic.

The following instructions allow for moving an ARD installation and/or the library of machines, stored commands, groups, etc. that collect with heavy use.

These are all the relevant files to make ARD work, assuming ARD doesn’t exist on the target machine already:

• /Applications/Remote Desktop (the application)
• /Library/Application Support/Apple/Remote Desktop (folder)
• /Library/Documentation/Applications/Remote Desktop (folder)
• /Library/Preferences/com.apple.RemoteDesktop.plist (serial number info)
• /Library/Widgets/Remote Desktop.wdgt (the ARD Widget)
• ~/Library/Application Suppor …
