When my code bites me on the you know what

I released ReceiptWallet 2.0 on Tuesday and the reception has been pretty good. Unfortunately, as with any major upgrade, there are bound to be issues. I've been handling the support issues on a case by case basis, and I've been scratching my head trying to figure out what could have caused the issues. This afternoon I received a phone call from my uncle who just upgraded and now his data was empty. The good thing about the upgrade is the chances of destroying the data are slim; ReceiptWallet, in most cases, can't find it. Having visited my uncle back in November and knowing how his system was setup, it made getting him up and running much easier. Then, this evening, it dawned on me the problem, so I tested my theory. In ReceiptWallet and DocumentWallet, I had a preference that let users move the ReceiptWallet or DocumentWallet data folder as people wanted to put it in Documents or on another hard drive. So I moved my data in ReceiptWallet 1.5.2, upgraded to ReceiptWallet 2.0 and saw that ReceiptWallet didn't find my data. Hmmm...at least I could reproduce it.

I started poking at my code and within a few minutes, saw this:

		[[NSUserDefaults standardUserDefaults] objectForKey:kOldDataLocation];

That's the whole line. Anyone who knows Cocoa programming knows that this does nothing. The line was supposed to be:

		dataLocation = [[NSUserDefaults standardUserDefaults] objectForKey:kOldDataLocation];

I somehow left off the assignment to the variable.

OK, simple fix. However, this doesn't really help the people that have already upgraded and our stuck. In addition, I'm not quite ready to put out a 2.0.1 version. So, I added a menu option that says "Open Prior Version Data" which does the magic to open the data file and actually executes the problem line of code from above.

So, I've posted the new version as a beta, put a Knowledge Base article about it and put a ReceiptWallet News item about it. I'm hoping that I can simply point people to the beta version and their problems will disappear.

I'll probably sleep well tonight having found the answer to one of this week's greatest mysteries.

Writing handheld applications using the iPhone SDK

In the past week since the iPhone SDK event, there has been a lot of discussion about the limitations of the iPhone SDK. I think that the "limitations" are coming from people and developers that have kind of missed the point. The main concern with a cell phone/handheld device is stability, at least that is my take on it. Way back in 1997 when I started working on the Qualcomm pDQ phone (the first Palm OS based smartphone), my main concern was that the phone could not crash as it was a consumer electronics device. (Imagine your TV crashing because you tried to watch an episode of Lost that had some magic encoding in it.) Maybe I was a little before my time, maybe not. The biggest problem with the Palm OS (up until just a few years ago) is that it didn't have flash based storage, so if the battery died, you'd lose everything. So not only could the phone crash, but sometimes in order to reset the device you had to pull the battery causing you to lose all your data.

I've just started to watch the iPhone SDK videos and will start taking a look at the SDK in the near future (I'm kind of working on 3.5 half time projects which leaves virtually no time to think or write this blog :-)).

One Mac developer has posted a list of its feature requests for the iPhone SDK. These requests are coming for a Mac developer and NOT a handheld developer or average consumer. As someone that has written handheld applications for the last 13+ years, I know that desktop development is completely different from handheld development. While the tools may be the same and it may use the same language, there are tons of differences. The primary concerns with handheld apps are stability and ease of use with limited screen real estate and input mechanisms. I hope that Apple ignores most of the requests from developers to give root access on the iPhone, allow access to the entire filesystem, and the ability to run background apps, just to name a few. These items will (not can) cause instability in the phone and provide a poor user experience that will reflect poorly on Apple. Furthermore, one app touching the entire phone could cause other applications to have problems and then people would come running to me (kind of like they do on the desktop, but more so).

Maybe I'm just jaded, but I want a stable, well functioning iPhone with good applications. I don't want a bunch of hackers or desktop developers writing crap for the iPhone. I guess we'll just have to wait and see how the market shakes out.

(I double checked this post and all the information above comes from public sources; I highly respect the agreements I sign, either physically or virtually, and I hope that others do the same.)

$2000 dog bone

No, we don't feed our dog diamond studded bones or anything like that. We've been letting him chew on a plastic Nylabone. He loves them and goes through them periodically. Well, on Sunday we were playing with him when I noticed a tooth fragment on the ground. My wife looked in his mouth and saw the tooth with the pulp exposed. After reading that this could be serious, I took him into the vet yesterday. The vet said that it was a fractured tooth and the tooth was a major one. The only option is root canal since Marley (the dog) is only 3.5 years old (older dogs he'd recommend just giving antibiotics and depending on the tooth, extracting it) and he really needs the tooth.

There are basically 2 veterinary dentists in Southern California; one here in San Diego (there are less than 100 board certified veterinary dentists in the world). The vet called later in the day after talking to the dentist and gave me the bad news; it was going to be close to $2000 for the root canal plus $250 for X-rays prior to the procedure. Ouch. So, the dog is scheduled for his root canal next Friday. While we have pet health insurance, I think we'll be lucky if it covers half. (Yes, we have insurance for our dog; while it may seem frivolous to some, the costs as seen here, for some procedures are extremely high.)

I hate that this is going to cost a chunk of change (and will likely delay the purchase of some stuff), when do you say stop paying for your pet? Isn't your pet family? I know that Marley is a big part of our lives and I can't imagine life without him. I know that his time will come, but until that happens, we're going to do all that we can do for him.

ReceiptWallet 2.0 Released!

I am pleased to announce that ReceiptWallet 2.0 has been released along with a completely redesigned website! Thanks goto Julie Bender for the new website design, my beta testers for finding all the bugs that I couldn't have found on my own, Eric Ullman for my press release, and of course, my wife, for putting up with me while I got this release out the door!

I'm very excited not just about the software release, but about the website as it now looks professional and all 5 components of my site are themed the same (the main site, the knowledge base, the store, the news area, a WordPress install, and the contact area). A lot of work went into getting this site to work smoothly and I think it looks great! I'm biased, but I've seen few "indie" developer sites that have the same look on all pieces of their sites; some get close, but leave out a piece here or there. I figured that while I was getting my site redone, I might as well go all out and make it all be consistent (as much as possible). My site looked like crap before and I should have made the leap earlier to get a professional to do it, but that's now 20/20 hindsight.

Oh, and this ReceiptWallet upgrade is FREE to all ReceiptWallet and DocumentWallet users!
