My iPhone Car Kit

January 5th, 2009 by Jim Shank No comments »

You never realize how well you have integrated technology into your life until you try to replace it. One thing I had down was my Treo 750 in my car. It had a suction mount, bluetooth GPS and charging. When I purchased my iPhone I hadn’t given a lot of thought as to how I would use it in the car. I already had an iPod kit for my Pioneer stereo using Pioneer’s CDIB100 iPod connection accessory. Unfortunately, Apple changed the charging method on the newest iPhones and iPods which left my car-kit able to play, but not charge. So began the project.

I thought I was pretty well set already having the iPod interface. Even the charging problem didn’t bother me, I mean, how hard is it to send 5v down the USB line instead of 12v down the firewire line. It turns out… very. Luckily Scosche had a simple solution in their charging adapter. Wait, what is that in the fine print? Doesn’t work with Pioneer iBus adapters including… mine?!

Well, that’s not going to stop me. After doing some pin-out investigation and having nightmares about letting the magic smoke out of my beautiful new iPhone 3G, I decided it was time to come up with something custom. My first stop was the forums on theiphoneblog.com and ilounge.com. They lead me to a great little company called ProClip that makes in-car mounting for any car and any device. I liked this modular design since it would allow me to move my iPhone into my Jeep Commander when I get it this summer. The price of the rotating clip was a little steep, $100, but I decided I liked the idea of being able to orient my iPhone either direction for future turn-by-turn applications for the iPhone so I bought it and the Jeep Cherokee adapter. This mount also has a very nice pass-through adapter so you don’t have to plug and un-plug your connection, it’s more of a dock and it works extremely well.

My next stop was audio and power connections. This is where you get screwed. Apple has the right cable,but it’s expensive to the tune of $50. That at least gets me audio out, now for charging. The XtremeMac InCharge Auto Charger for iPod/iPhone fits the ticket providing an Apple certified 5v USB connection for auto. Now everything is installed, clean and works great.

I accidently deleted all the pictures I took of the installation. Sorry guys and gals.

I can't believe it, I got an iPhone, and…. I like it.

A few weeks ago my lovely wife got me an iPod Nano for my birthday. This wasn’t something on my list or anything I knew I wanted but I swallowed my dislike for all things from that white-clad trouble maker in Cupertino and gave it a try. The interface was very simple, I never had to break out the manual or even go looking for a feature. I thought the accelerometer would be cute and nothing more than a gimmick but it was actually useful in the control of the device (especially in the games). In short, I really liked it and I wanted more. » Read more: I can't believe it, I got an iPhone, and…. I like it.

Asterisk Still Rocks

May 29th, 2008 by Jim Shank No comments »

A few days ago I heard a knock at the door and went to see who it was. I usually just don’t open the door for people I don’t know but the kid looked so excited for someone to open it that I did. He was offering Comcast IP phone service for $20 a month and offered to discount my Comcast High Speed Internet $10 a month if I signed up. Telephone service for $10/mo! I had to break the news to him that I had that price beat.

“How could that be?”, he asked.

“Well, Asterisk”.

SharePoint Services Upgrade from 2.0 to 3.0 Goes Horribly Wrong…again!

April 1st, 2008 by Jim Shank No comments »

Those who do not learn from their mistakes are doomed to repeat them. Yep.

About a year ago I did an upgrade for a company from SharePoint Services 2.0 to 3.0 and basically fought it for 3-weeks on and off. I just did an upgrade for the company I worked for again and sure enough the exact same things happened. I assume you are here because the SharePoint upgrade didn’t go quite right for you either. Maybe you didn’t have all the permissions needed, you had administrative rights to the server but not the database, oops. I am blown away that the installer will let you corrupt the database to an unusable state, no fear, you can recover and here is how.

What you see: Unable to get global configuration data

This is the first indicator of trouble, for me it meant that I had partially updated my database schema but rolled back my WSS to 2.0.

Do This: Rerun the upgrade to WSS 3.0 and follow through the upgrade handling any errors below.

What you see: An Microsoft.SharePoint.Administration.SPServer named “sql” is using the same id as the new object named “sql” of type Microsoft.SharePoint.Administration.SPServer. Every object must contain a unique id. Either update the new object’s id or delete the existing object and try again.

Do this: Clear out the Dependencies and Objects tables. To do this, go to Query Analyzer or Microsoft SQL Management Studio (Express) and enter “delete from objects; delete from dependencies;”, select the SP database and click on EXECUTE. If you try to do these individually, you will get dependency errors that are pretty miserable to resolve. I know, I did first.

What you see: The pre-upgrade scan tool has not yet been run on this database SPContentDatabase

Do this: From a command line run: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN\prescan /all then try the upgrade again

Microsoft is in trouble, Mac is using the Big Tobacco approach

March 13th, 2008 by Jim Shank No comments »

My wife and I recently attended our kids 1st grade patriotic presentation. It was adorable and sweet, the kids all sang and gave speeches on American symbols like the flag and the statue of liberty. After the presentation we were taken back to the classroom and our kids got to show us the work they had done to prepare for the patriotic presentation including an individual multimedia CD. Being a tech geek myself I was very interested to see this presentation so we headed off to find a computer to view it on. There was a set of about 20 Mac laptops sitting on desks in the pod area, all in use by kids showing parents their presentation. The classroom computer was already in use. We headed off to the lab and found another 50 Mac’s in-use and not a single seat available. Next stop was the library. There were 15 Mac’s and 15 Dell PCs along the wall. Every single Mac was in use as well but the PCs sat untouched. My son looked up at me and said we would have to wait for a computer. I was in complete disbelief that my son, who had used a PC since he was 3 years old was completely PC illiterate. I told him to his surprise that we could watch his presentation on one of the available PCs. We sat down and I blew the dust off the keyboard and mouse and up came the Ctrl-Alt-Del login screen. I am not sure how a 6-year old is supposed to understand this screen and why the school would leave the corporate login screen active when it was just as easy to setup the more friendly Welcome screen up with fun icons to login with. I went ahead and gave the 3-finger salute and up came the username and password which, of course, my son had no idea what his login information was. The very sad part is that I work for the technology department for the school district and had to use my login to get to the desktop. » Read more: Microsoft is in trouble, Mac is using the Big Tobacco approach

How to Copy Series DVD's into MythVideos

February 4th, 2008 by Jim Shank No comments »

One of the big benefits of Myth is on-demand access to any episode of your favorite shows. I have a few full-series on DVD’s and wanted to find the most efficient way to copy them onto my Myth system. The first tool you need is something that can copy the DVD episodes individually to be processed into AVI’s. DVD Decrypter fits the bill nicely although there are many tools you can use. The big time saver is a nice little batch file called DVD Decrypter Multiple Feature Ripper. DDMFRip is a simple menu driven process that will allow you to define the basic structure of a DVD through a series of questions and then create multiple subdirectories correctly named for the series you want to copy. You can get a copy and a more in-depth guide here. I made one small change to the ddmfrip.bat file that capitalizes the E for episode in the filename so that a step in the later process of inserting video metadata into MythVideo will work correctly. » Read more: How to Copy Series DVD's into MythVideos

Whim Discovery: My Experience with Asterisk

January 25th, 2008 by Jim Shank 2 comments »

It all started at Barnes and Noble in Downtown Denver. It was our anniversary weekend and one of the things we like to do downtown is hit the bookstore and enjoy quiet reading time. I was looking for a book on SELinux which I just couldn’t find in the Linux section. I came across another O’Reilly book called Asterisk: The Future of Telephony. I enjoyed a sunny afternoon reading through the book next to my wife. I only made it a few chapters in but I was hooked. I had just completed a MythTV project and was saving dough on TV already, why not the phone too! After we were done, I put the book back but the fire had already been started. » Read more: Whim Discovery: My Experience with Asterisk

CAT5e vs CAT5E vs CAT6 vs CAT6a

January 17th, 2008 by Jim Shank 1 comment »

After much research, it appears that CAT 5E (big E) is a marketing ploy and doesn’t comply to any standards. It’s rumored to support 350MHz of bandwidth but I couldn’t find any real facts. Here are the actual standards:

  • Cat 5: Currently unrecognized by TIA/EIA. Provided performance of up to 100 MHz, and was frequently used on 100 Mbit/s ethernet networks. May be unsuitable for 1000BASE-T gigabit ethernet.
  • Cat 5e: Currently defined in a
    TIA/EIA-568-B. Provides performance of up to 100 MHz, and is frequently used for both 100 Mbit/s and gigabit ethernet networks.
  • Cat 6: Currently defined in TIA/EIA-568-B. It provides performance of up to 250 MHz, more than double category 5 and 5e.
  • Cat 6a: Future specification for 10 Gbit/s applications.
  • Cat 7: An informal name applied to ISO/IEC 11801 Class F cabling. This standard specifies four individually-shielded pairs (STP) inside an overall shield. Designed for transmission at frequencies up to 600 MHz.

This leads us to a question of price.

Cat6 Cat5e
1000’ Cable (Plenum rated) $326.00 $183.00
RJ-45 (Stranded) $0.73 $0.25
Wall jack $6.39 $3.20

Generally you can expect about 2x the price but will support 10x the speed (10GB). These prices are from a few sites on the internet and aren’t by any means representative of all pricing. The general feeling from newsgroups and forums was that the expensive part was the labor so installing Cat6 was still the better choice if you have a new installation.
