Next I tried ripping it on my MacBook Pro with HandBrake. It ripped into an m4v file but the sequence of the movie was all scrambled. This wouldn't work either.

I told my daughter the bad news. She looked at me and said matter of factly, "...just put the DVD in your MacBook and play it over on the Mac Mini." A brilliant idea if it were possible. I initially told her that it wasn't possible, but then I remembered Apple's Remote Disk Sharing feature that is normally used to install software on the MacBook Air and other computers that do not have optical disk drives.

I went into the Sharing section of my MacBook Pro's System Preferences and turned on "DVD or CD Sharing." I next went to the Mac Mini and waited. Nothing. Remote Disk is supposed to show up in the sidebar of the finder window. Nothing.

It turns out that this feature is not enabled on some Macs. After a bit of Googling, I found this:

http://www.macosxhints.com/article.php?story=2009012605560521

Open terminal on the computer that needs to access the remote DVD drive and type:

defaults write com.apple.NetworkBrowser EnableODiskBrowsing -bool true

And then:

defaults write com.apple.NetworkBrowser ODSSupported -bool true

I logged out of the account and then back into it again. Now I could see the remote disk (DVD) loaded on the MacBook Pro while looking at the finder sidebar of the Mac Mini. Great! I opened up DVD player on the Mac Mini, navigated to the remote DVD and received an error that the disk was "...copy protected blah blah blah."

Googling more I found a number of posts stating that this procedure could not be done due to the copy protection restrictions put in place by Apple. I was just about to give up hope when I thought of VLC (Video Lan Client). I opened up VLC, browsed to the remote DVD, and lo and behold, IT WORKED! We are now watching the DVD on the Mac Mini as it is being played on the MacBook Pro's DVD drive.

My daughter has mad skills!

P.S. This got me thinking. Why doesn't Apple just allow this by default? I'm jumping through way too many hoops just to play a movie that WE LEGALLY OWN. *sigh*

Long story short, this Mac's drive was shot. The drive not only wouldn't boot properly, it wouldn't even mount in target disk mode. I could boot the Mac in singler user mode (restart holding down command+S) which enabled me to see the files via command line so I knew that they were still there. I just couldn't get to them. To make matters worse, my brother in law then informed me that he had very important files on the computer related to an audit that he was involved in at work. No backups. Not good.

Here's what I eventually had to do to recover the files. I connected a FireWire drive to the Mac Mini and booted it up off of a retail Mac OS X 10.5 DVD. Once I could see the Utilities menu, I opened up terminal and ran:

cd /Volumes

and then:

ls

This returned:

Macintosh HD  FireWire HD

Now that I was sure that the two drives could be seen via command line, I did:

cd Macintosh\ HD/Users/

then:

cp -R brotherinlaw/Documents/ /Volumes/FireWire\ HD/

Once the cp command completed, I did:

ls /Volumes/FireWire\ HD/

This resulted in seeing that all of the files that my brother in law needed were now on the FireWire drive! I'm still in the process of backing up data. I'll update this post as soon as I know one way or another if I was completely successful.

One very strange behavior ocurred in that the failing drive (Macintosh HD) wouldn't show up in the Mac OS X Installer until I opened up Disk Utility from the Utilities menu and clicked on its root partition. After I did that, I quit out of Disk Utility and eventually it showed up in the installer. I could then see the drive when I did a:

ls /Volumes

These commands explained for those of you new to Unix:

cd = Change Directory

ls = List Files

cp -R = Copy Recursively

UPDATE: It worked.

"Locked out!
We've temporarily locked your account after too many failed attempts to sign in. Please chillax for a few, then try again."

I know my login information and have it saved in my web browser, so what could possibly be causing this? I believe that the answer lies in the ever increasing amount of Twitter accounts that are being hacked and exploited for spamming.

Could people be attempting to hack into accounts using brute-force hacking methods? I'm sure it's possible, and probable.

Twitter's answer to this issue, however, is extremely vexing. Because someone is trying to hack into "my" account, Twitter locks ME out of it!? Um...is this really the best solution to this problem?</sarcasm>

Why not use IP address restrictions instead of globally locking down the account. If someone types 3 bad login attempts from an IP address, refuse all login attempts from that IP address UNLESS that IP address has been used in the past to successfully log in. In that case, make it 5 unsuccessful log in attempts before that IP address is locked out. How about allowing users to force Twitter to ONLY allow logins from specific IP addresses?

Don't like these ideas as default settings? How about making them an optional checkbox in the Twitter settings?

[  ] Use IP address login restrictions.

[  ] Only allow logins from the following IP addresses

etc...

All I know is, getting locked out of my Twitter account when I'm increasingly relying on it for communication and learning is a real pain.

Could someone be silenced for their views on Twitter? Absolutely. All someone has to do is try to log into an account over and over again and that user is locked out of it. This doesn't seem very functional, dependable, or even usable.

Twitter is many things to many people. If they want many of us to rely on it for professional social networking, IMHO they need to make it more robust, consistent, and designed with mission critical uptime, connectivity, and "loginability" in mind. (Ok...loginability isn't a word. Put the word or phrase that I'm looking for in the comments.) :)

I hope Twitter fixes these login restrictions real soon.

Recently, I asked the students in my Digital Audio Recording and Production class if they would record a radio commercial for our school. They agreed and were given a script that was prepared by the Director of Marketing for CCHS, Lisa Bowling.

We looked at the script together, and I assigned students to play the different characters in the script. Once that was done, I let them take over the entire project. One of the students acted as the recording engineer, and the rest did the voiceovers. Once they told me that they were finished, I was completely blown away by what they had done.

Check out the radio commercial that they created entitled, "Just say yes!"

Feel free to leave some feedback in the comments so that we can improve with the next one.

Funny thing happened with that, however. As a result of working with the German teacher, I had my Mac switched to the German keyboard layout and mapping. I then left my office for some time to take care of some business on the second floor and returned only to find the screensaver asking for my password. Oops! Because I didn't switch back to the U.S. mapping prior to leaving my office, my keyboard was still in the German layout. The characters in my password that were now mis-mapped were not allowing me to authenticate to my account. What a nightmare!

Jeff Sankovich said, "Why don't you use fast user switching." He believed that by doing so you would then be using the keyboard layout of the other user and not your own to authenticate. It worked! I switched users and then used fast user switching to get back into my account and QUICKLY changed my keyboard mapping back to U.S.

Kudos to Jeff.

I've been meaning to do this for far too long. I'm glad that I finally got started. Please return in the future to see many, many changes to this site.

Thank you for visiting.
