How to download and record any video stream to disk using VLC

ymeme — Mon, 08 Dec 2008 10:39:07 -0500

You can download, view and record any type of video stream (including Real) VLC 0.8.x can handle. This works perfectly well using Mac OS X as well.

In most cases, you must go for the link inside the site's source code. An example is a news video stream which uses the WMP plug-in: view the page source, copy the MMS link, and paste it in the proper field in the VLC dialog window (see below). Then, assuming VLC is already running:

From the File menu choose the Open Network menu option.
In VLC, choose Open Network, and paste your MMS (RSTP with Real) link in the appropriate field.

ymeme — Thu, 17 Jul 2008 09:33:52 -0400

Copying a directory tree and its contents to another filesystem using

cp -pR directory /newplace

doesn't always do the job.

Using tar instead will preserve ownership, permissions, and timestamps. This neat trick allows using tar to perform a recursive copy without creating an intermediate tar file and overcoming all cp shortcomings.

To copy all of the files and subdirectories in the current working directory to the directory /target, use:

tar cf - * | ( cd /target; tar xfp -)

Today, after upgrading one of our machines to the latest security update, the iMac G5 stopped booting. Starting the machine in Single User mode (command+S) revealed that the mDNSResponder daemon was crashing and restarting in an infinite loop.

'The Mac was stuck in a loop trying to execute mDNSResponder (which is the basis of Bonjour networking) and the system wasn't successful.

On the Apple forums nobody is able to pinpoint the problem yet, but it looks like it is a pretty common disease. If you do not need Bonjour, this is what solved it for me:
