Over the Air HDTV - My interview with WJAR
I got interviewed by our local NBC affiliate, WJAR 10, about a month ago for a segment on over the air (OTA) HDTV. It aired last night and apparently again tonight because they got so many calls about it. It was a lot of fun being the technology evangelist for OTA HDTV for Rhode Island.
First, here's the link to WJAR's page for the segment, where you can watch the video.
Not bad, huh? I was a little nervous and forgot to mention a couple of things during the interview. While I did mention that I get all the Boston stations with my OTA antenna, I forgot to note that Cox doesn't carry any of them, whether in standard def or high def. Also, despite what the operations guy from Cox said, you can totally tell the difference between the recompressed HD signal on cable and the pure OTA signal.
For the most part, 98% of what's on regular cable is crap. I will admit that I love the original series on HBO and Showtime like Deadwood, Rome, Weeds, Six Feet Under, etc. I see them when they come out on DVD. I like watching a whole season of something in one shot anyway. Except for those few series, how many times can you watch Beverly Hills Cop on HBO? There are also a few of those reality competition shows on Bravo (Top Chef, Top Design, Project Runway) that we don't get to see live. But if we're really dying to see them, we can always get them from the iTunes store.
When you figure that I'd pay about $100 per month for the pleasure of having all that entertainment piped into my house by Cox every month, I'm way ahead of the game by going OTA for network television and then buying everything else a la carte.

Tamrac 5691 - Killer Little Digital Camera Bag
I was in a photo shop yesterday killing a little time before a haircut and came across this nice little bag for my digital camera. Tamrac makes excellent soft sided bags for all sizes of cameras, from SLRs to tiny digitals. This bag is great for my Panasonic Lumix. The camera fits perfectly in the compartment and the front pocket has plenty of room for cables, extra batteries and memory cards. This is a quality bag made here in the States, with real metal D rings and clips for the straps. If you're in the market for a camera bag, check out Tamrac, you won't be disappointed.

iTunes shared local Library
I recently helped a friend reinstall his Mac from the ground up. He was having no end of trouble with conflicts between his new Wacom tablet's drivers and Norton Anti-Virus (worst AV program ever). While we were at it, we partitioned his drive into system and data partitions so if he has any trouble in the future he won't have to worry about getting all his data backed up.
We decided to put his iTunes music on the data drive and make it shareable between him and his partner. This requires a little tweaking of permissions and adding a group, but will be worth it in the end.
Full instructions after the jump.
After partitioning the drive and reinstalling OS X, you will have a system partition and a data partition. Having separate partitions is not required for this, but it's just how we did it.
- Start iTunes to initialize your ~/Music/iTunes directory (skip this step if your iTunes directory already exists.)
- Move the "Music" directory out of your home directory to the shared location (here we moved it to the Data partition.)
- Select the Music directory from its new location and 'Make Alias'
- Copy "Music alias" to your home directory and rename it "Music" (removing the " alias".)
Now you've got the files in the right place, but they're still only accessible to one user. Here's where things get a little complicated. We need to make a group for the music users. This will allow us to set permissions on all the directories and files so that the members of the group will be able to make changes (create playlists, update ID3 tags, etc.)
- Open NetInfo Manager
- Click the lock and enter your password to make changes
- Select Groups
- Select the "admin" group
- Click the "Duplicate" button
- Select "admin copy" and change the "name" property to "itunes-users"
- Change the gid of "itunes-users" to 401 (this should be a safe value as system groups stop at 99 and user groups start at 500)
- Edit the users property to include the right users. Here we have marge, homer and barney. Use "Insert Value" from the "Directory" menu to add more users if required.
- Command-S to save.
Now you have the group created. All that's left is taking care of permissions on the Music directory. I have created a script that will run once a day to handle this. It needs to be installed with permissions 755 in /etc/periodic/daily (get a Unix knowledgeable friend to help if you have no idea what that means.) This script will go through your music directory and set the group ownership to itunes-users and set all the directories and files read/write for that group. This will allow all of the itunes-users to add files and modify ID3 tags.
#!/bin/bash
#
# iTunesShareFix
#
# iTunes Shared Library Permissions Fixer
#
# This periodic script will fix the permissions of a directory tree to
# allow multiple users to shared read and write access that tree. This
# is most useful for sharing an iTunes music library between multiple
# users on a single Mac.
#
# Install this script with permissions 755 into /etc/periodic/daily
# and it will run once a day as long as your Mac is running at night.
#
# If your mac if off at night (putting your powerbook to sleep for
# example) you should get the anacron package from:
# http://www.alastairs-place.net/anacron.html
#
#
###############################################################################
# Variables
###############################################################################
#
# SHAREGRP - All users that should have access to the library will
# need to be part of this group
SHAREGRP="itunes-users"
# SHAREDIR - The top level directory under which everything will be
# read and write accessible for members of SHAREGRP. Be sure to
# include the directory that holds the "iTunes Music Library.xml"
# files so that everyone has the ability to make playlists.
#
SHAREDIR="/Path/To/Your/Music"
################################################################################
# Don't Make any changes below here unless you know what you're doing!
################################################################################
find "$SHAREDIR" -type d -exec chmod 775 "{}" \;
find "$SHAREDIR" -type d -exec chgrp $SHAREGRP "{}" \;
find "$SHAREDIR" -type f -exec chmod 664 "{}" \;
find "$SHAREDIR" -type f -exec chgrp $SHAREGRP "{}" \;
This script wouldn't be required if there was some way to run iTunes with a umask of 002. If anyone knows how to do that, I'd really like to hear about it.

Cool Looking Multi-Point Bluetooth Headset from Plantronics
It would be sweet to get work to pony up the cash (US$249) for this new Bluetooth headset from Plantronics. It is supposed to be able to seamlessly switch between analog mode (connected to your office desk phone) and mobile mode (connected to your bluetooth enabled mobile). I would dig that as I have headsets for both my mobile and my desk phone at the office. However, at 3.1 ounces, this thing could get a little heavy after a while and my ears are uneven enough all on their own.
