In today’s world of consumer software, the phrase “software is never done, it’s just shipped” is the norm. Prior to the wide use of the Internet and downloadable updates, this wasn’t always the case. When it cost real money to send out updates on media, software was tested more, but also people didn’t expect updates as often. When I released ReceiptWallet 2.0 last week, I knew there was going to be an update. I released 2.0.1 this past Sunday and followed it up almost immediately with 2.0.2 b1 as I found more issues.

This phrase may sound like a cop out, but I believe that it is the only way to write software. There are far too many variables to produce a product and have it work everywhere. There are some many different models of computers, various operating systems, hacks that modify the system, different applications that produce PDFs, etc. 10+ years ago, the combinations were far fewer, so it was easier to fully test a product. It is just not practical or even realistic to believe that anyone can ship consumer software that is bug free. Notice I said consumer software; if you have complete control (or significant control) over all the variables like the software in a microwave or a cordless phone, shipping bug free software is possible.

Having said that, I personally like more updates rather than big, infrequent updates. As a developer, this lets me get out fixes to those that need them and as a user, I like to see that developers are actively working on the product.

I’m a huge fan of the Sparkle framework and think that all programs should have this type of update mechanism built in. It makes it simple for users to get the updates and automatically install them. So, pushing out updates is quite easy.

I have to admit that some of my error messages to users aren’t that friendly, but I’ve tried to put in a message at least that says “Please contact support and report the above error.”. Sometimes I can help users, sometimes I can’t. I was using QuickBooks today and I received the following error message:

That’s a huge help! It doesn’t tell me what to do, what happened, or how to correct it. Personally I think it looks completely unprofessional to display build paths in error messages. While they might help Intuit fix the issue, I don’t even have a clue where to start reporting that. Do I contact support@intuit.com or do I have to go through their web based system? I don’t want an answer, I just want to report it.

I received an urgent email from a user today that had a slight problem with a registration code. I responded within a couple of hours (today is Saturday) saying that I tested the code and it works fine (I actually did test the code and saw that it worked) and said please try again and if you have problems, please send a screenshot so I can verify the code. The response I got back was “I am very disappointed with your response.” Wow, it is those kind of users that make me want to quit writing and selling software. I generally get back to users within a few hours, 7 days a week; yes, I work a lot and some people appreciate that. Some support tickets take a bit of going back and forth and I’ll work to solve problems as much as it takes. However, getting responses like this make me want to just pack it in.

I generally expect an answer within a few days to any email I sent. (I have, however, been waiting 2 months for a response from IRIS about returning my crappy scanner, but that’s another store and I should just send them a certified letter and demand my money back as the product was falsely represented.) On weekends, I don’t expect any response as normal companies don’t have people working on weekends.

Oh, and ReceiptWallet 2.0 resets the 3 week demo period, so even if I didn’t get back quickly, all users would still have time to use the app before the demo expired.

Uggh.

Yesterday I wrote that I didn’t think background applications were a good idea on the iPhone and I’ve seen some other posts that support my position; anything that makes the phone less stable is bad. A good friend of mine pointed out why a background app would be good, but also reminded me of how this was handled on the Palm OS. Notifications were posted. So an application would register for a notification or set an alarm for a specific time and then would handle that. While I’m not saying the Palm OS was perfect (if you ever wrote Palm OS software, you remember that notifications and alarm callbacks had to reside in the first 16K (or was it 64K) of the application thereby causing you to use jumps to get stuff to work. If you don’t have a clue what I’m talking about, feel lucky.

The iPhone could do something similar (maybe it already does, but I don’t know and even if I did, I couldn’t say publicly until June). I’m sure that the iPhone SDK will mature as time goes on, but I hope that developers remember that the iPhone is a phone and music player first, and an application player second (or third or fourth). If anything takes away from its main purpose, it will hurt the platform.

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.)

In ReceiptWallet 2.0, I use an ellipses in a number of places for menu items, window titles, etc. I switched all my source files to UTF-8 and started using ellipses in the NSLocalizedString macros to make localization easier whenever I get to that point. Well, despite using UTF-8 for the file encoding, something went horribly wrong that I didn’t notice until today. The ellipses caused a bunch of my menu items to take on names of other things, like Scan Receipt became Combining Documents…. Huh, I thought. So after a bunch of research, I found the solution. 1) Replace … with \\U2026 and 2) In my script phase where I run genstrings to generate the Localizable.strings file, add a -u flag. While that seems like an easy fix, I almost went bonkers today as I’m nearing the ReceiptWallet 2.0 release and this would have been bad.

There have been a number of postings about having a Cocoa document based application where the documents are packages. None of the posts seemed to nail exactly what I wanted, so I managed to piece together a bunch of posts and came up with some sample code to demonstrate it. I used this as a basis for ReceiptWallet 2.0, but have made a bunch of changes since then. Feel free to use this code in any way you see fit, but I make no promises of how well it will work for anyone besides me.
