Lego Raspberry Pi Cases
I made it so it could be mounted on the wall. Additionally, the left side opens to expose the GPIO pins, although I doubt you could fit something on them without having to remove pieces from the case.
A friend of mine also has a Pi, but he was using a plastic food container for its housing. I simply could not stand for this, so I created another case for him:
This one doesn't mount on the wall. I think he's just using it on an entertainment center near the cable modem box. Unlike my case, it opens fully, exposing the entire board. I forgot to take a picture of this feature, but you can see the hinges on one of the side photos.
Both of these cases use some classic Lego pieces that I received from my cousin when I was a kid. The old-school computer terminals in blue and grey and the pieces with space logos came from this set, and I mixed them with some newer space buttons and circuitry. The glass-like covers are also newer, but have a similar hokey space feel to them.
It was fun putting my old Legos to use again!

AHIP Insurance Course
First, I had a number of problems accessing the presentation online. When I would try to load the presentation in Firefox, I received an error message from Java. I tried it on Internet Explorer and received the same message. I checked my version of Java, and it appeared to be up-to-date. I also check my security settings in both Firefox and Internet Explorer. Nothing seemed to be blocking it. I also checked my firewall, but since I was in a hurry, I didn't check it thoroughly. So then I tried my wife's laptop, which is less secure than my desktop PC in terms of browser security and firewall settings, and it worked. I studied using her computer for a few weeks until I had some time to investigate issues on my PC. Finally, I manually updated Java and changed my firewall settings to asked about network connections. It turned out that the Java applet AHIP was using was out-of-date, and I had to allow an exception. I'm not sure if the update or the firewall change resolved the issue, but it worked on my PC.
The presentation itself was also problematic. The data presented was out-of-date by at least 10 years, as the presentation only included data up to the 90s. It appeared that many of the terms, definitions, and trends were also quite out-of-date. The presentation also included a number of "Knowledge Checks" to see if you were understanding the material. About 90% of the time, these questions were completely irrelevant to the material. At first I thought they were from a different chapter, but now that I've finished reading the material, I don't think they were even from the right course. The answers to the questions were not provided in ANY of the material. Fortunately, these questions were only intended to help the student study and did not count toward the final grade. I'm not even sure AHIP even kept track of the answers.
I had contacted AHIP about both problems - with access and the questions - however, they were not much help. The guidance on updating my PC did not help, nor did the tip that "these intermediary quizzes are not graded" - basically saying "skip them". Open the following link to view the email conversation with the AHIP representative:

At any rate, I was able to overcome these issues, study the material, and pass the test. There were issues with the test, too. The location for accessing the test was oddly placed at the end of the presenation content. If you clicked on it before you were ready or before your test time, that took up 1 of 2 test opportunities, since it would load the official test. I heard a number of people saying they accidentally clicked on it or expected it to be a practice test. This seems to be a bit of poor design.
The test format was a bit odd. It consisted of a number of frames with the browser, with a convenient clock counting down the time left for the test. The questions were multiple choice, but included poorly-written answers like 1) A and B; 2) B and C; 3) A, B, and C; 4) Only A; 5) Only C. These types of questions do not really increase the ability of the test to distinguish between those test-takers who know the material and those who do not. Simpler questions with 3 or 4 clear choices for responses would be adequate.
Some features were actually very convenient, helping the test-taker. One was the "Review" button, which once pressed would flag the question and put it on a list for you to answer later. The other was the button that showed the list of questions to review. The next button, as I heard from a colleague, changed from "Next" to "Submit" on the last question, which is not good if you're not paying attention to the number of questions you've answered. She clicked Submit by accident, without reviewing the questions she had flagged, and as a result, failed the test. Once I completed the test, a list of the questions I answered correctly appeared. Apparently there was a link at the bottom that showed the total percent correct, but I did not see it. I clicked the "Home" button to check to see if I passed the test. When I went back, it did not load the test results. I suppose it was a safety mechanism so that the user does not overwrite a test that was just taken, which would not be good, especially if the taker passes it the first time and fails it the second.
Although all of these problems were present, I did learn quite a bit. The course had a lot of good information about how the insurance industry works and huge number of common terms and definitions. There was some information I did not find as relevant, for example, commissions for agents/brokers, but it would certainly be useful for someone in those fields or working with those fields. I heard feedback from my co-workers that sounded similar to my experiences, but I found that a lot of people order the books. I feel that's a bit wasteful; however, it would have avoided the problems with the online presentation and questions. In the end, the information I learned was very useful, but the presentation could have been better. I hope AHIP reviews the presentation and content and updates the content to include new data and up-to-date definitions.

My Tax Man
"You want ME to do your taxes?!"
"How on Earth do you organize your receipts??"
Actually, we used TaxCut Online to do our taxes. I'm sure Luca would have done a great job, though. He did seem awfully interested in my W-2s while I was working on it. Maybe he just wanted to eat them though.
TaxCut Online worked very well. For basic tax needs, it's quick and reliable. I spent about 2 hours working on it, and if there hadn't been a slightly confusing question about the Alternative Minimum Tax in Wisconsin, it probably would have been faster. Oh, and it would have been faster had I not been trying to complete it with my son on my lap, who likes to hit the mouse and keyboard! I also cleared my cookies on accident and had to log back in. Oops!
I used the software last year and it went very smoothly this year with the addition of my wife's tax information and our new deductions for our son. The software remembers data entered from the previous year and restores specific answers from last year's return for review. It does not allow a direct import of last year's data without review as a safety mechanism.
All in all, I could probably have saved a buck and done it on my own for the State and Federal taxes, but having the software to check over your work and the addition of on-demand support and assistance in case of an audit is a definite plus. Last year I did both TaxCut and the free State submission form, and I discovered that there was a difference in the return that was exactly the amount I paid for use of the software. There is a discout for tax preparation that TaxCut submits with you taxes!
Submitting taxes online is also incredibly fast. We received our State return in less than a week and our Federal return will arrive 9 days after I submitted it. Overall, I would definitely recommend this software to anyone willing to submit your tax information on the internet. Of course, if you have a complicated tax return, a professional is always the best and safest bet.

My Home Computer Desk
I have a bit of an unusual work space for my computer at home. On the right of the keyboard, I have a trackball mouse. On the left, I have a regular mouse that is not used for moving the cursor. I also have a wireless mouse on the monitor area of the desk and a video game controller. Here's a photo:
The trackball mouse aids with avoiding carpal tunnel syndrome and it saves space. The small left button is set to the middle button and the small right button is set to "Back" for internet and file browsing. The mouse on the left side serves two purposes: First, this style of mouse has a better scroll device than the trackball mouse, which doesn't really have one. Second, if it's ever necessary to get the precision of a regular mouse (editing images, for example), then it is available for use. The laser is currently covered with a small sticky pad to avoid any cursor movement from it. The wireless mouse is used for viewing the computer desktop on the TV, away from the computer monitor. It's great when watching internet TV shows on an actual TV (hulu.com is great for internet TV).
Also note the USB extension cord, which is useful for any other peripheral devices one would need to plug in temporarily (a camera, for example), and the wireless headphones, which allow for freedom of movement and less cord clutter. The small device under the monitor is a CRYPTOCard, used for accessing remote computers at work. The monitor is on a base that rotates and adjusts vertically, making it perfect for getting just the right position for the user. The combination of the trackball mouse and vertically adjustable monitor have significantly improved the ergonomics of my computer desk, making me a lot more comfortable, especially during long hours of work (or play!).Here's an older version of the setup with an older left mouse and keyboard and without the wireless mouse.
I (thankfully) upgraded the monitor from the bulky, unadjustable CRT monitor. Since I spilled juice on the keyboard (not recommended!) I had to get a new one of those too, although I went with a cheap keyboard. Actually, the only component I would change about the current setup is the keyboard, which isn't exactly comfortable and the extra buttons on the left and right sides are not prominent enough to be very useful. I liked my old one, but I spilled juice on it...
By the way, all of these devices except the keyboard are from Logitech. I really like their computer input devices. The software isn't completely bug free, but once I got the settings where I like them everything works just fine. I haven't used the wireless mouse as much, but I advise getting a USB extension cord with it, as its range is limited.
