No excuse for crappy UI

I’ve been reading about Stevens Creek‘s new TripLog/1040 application through some discussions about bad UI. Steven Patt, the author and long time Palm developer (like me, however I stopped a few years back), defends his decisions saying that users want everything viewable on one screen. While this may be true, this app looks like a horrible Palm OS app. It follows none of the Apple UI guidelines and looks nothing like any built-in iPhone application. There is absolutely no excuse for it; some of the buttons are far too small to actually hit on a device. They may work fine in the Simulator, but they are not usable. Then the background color is just awful.

He can justify his decisions all he wants, but this kind of UI just makes the iPhone look like a piece of junk. Developers need to adhere to the guidelines to make the platform look solid. Years ago I wrote an article for one of the Palm conferences about minor things developers could do to polish their apps, like have the correct button sizes and placements. Many Palm OS developers ignored it.

While I’m ranting about software, it was so nice of him to violate his non-disclosure with Apple by posting screenshots of his application. It seems like he wasn’t only in this violation. Does Apple care? I don’t know, but it annoys me to no end that even if I did have an app ready, I would have honored the NDA and not posted anything until I was released from the NDA. I would have hoped that Apple would have punished these developers by not accepting their apps into the AppStore, but this didn’t happen.

No financial incentive to recycle

Here in San Diego we have free trash pickup (for single family residences) due to the People’s Ordinance of 1919 which I believe came out of the city selling refuse to pig farmers and making money on it (hmmm, it would appear that the city leaders back then had some of the same issues of public trust as the current ones). With free trash pickup, what incentive do we have to recycle? We recycle as much as possible and just started a compost bin last week to reduce the amount we send to the dump. If the city wants to encourage more recycling, they should offer a financial incentive (don’t take away the free trash pickup) to say lower property taxes or something like that. The city is already in hot water as state law requires it to recycle more, but it isn’t meeting that. While people should just feel good about “going green”, let’s be realistic. Unless it positively or negatively affects people’s wallets, it just isn’t going to be adopted by everyone.

(I’m not new to “going green”; back in 1990, I started a paper recycling program for my Eagle Scout project. Times have changed, but I’ve tried to do my part to help.)

New features for newer operating systems

I’ve written a number of times (I think) about how long should I support an older OS. I’ve also said that I’m not abandoning Tiger users, quite yet, but I may have mentioned that new features are likely going to be Leopard only as required to make things easier. In the recent past, I’ve implemented 2 Leopard only features; the first is support for Image Capture scanners. Image Capture seems like a broken framework that might be fixed someday. In the meantime, the only way for me to reliably test and get things working is to require Leopard.

The other feature (which I just finished today) is allowing a library to be encrypted. The approach I took was to create an encrypted disc image and shove everything in that. Encrypted disc images are supported on Tiger, but one of the slick features in Leopard is a sparsebundle. What is a sparsebundle? Well, it is a growable disc image that has “bands”. This means that if you modify a few files in the disc image, only the necessary bands are updated. This is absolutely necessary for backups otherwise each time a user touched a ReceiptWallet library, he’d have to backup the entire disc image (backup apps do the right thing; it isn’t a manual process to copy the bands). With one of my libraries approaching 1 GB, that would be a complete waste of time. Time Machine uses sparsebundles for the Time Capsule and if it is good enough for Apple, it’s good enough for me! So, I’ve disabled encryption on Tiger. I’m sure that some people won’t be too happy about this, but doing encryption another way would have taken significantly longer with no true reward.

Everyday, I look at the statistics I collect on what operating systems users run. The large majority run Leopard. In the graph below, you have to make one big assumptions as the data is anonymous so users that check for updates all the time (more than the default once a day) will get recorded more than once, and that is that Tiger and Leopard users check for updates at the same rate. The actual numbers are irrelevant; it is the trends I look at and the ratio of Leopard to Tiger users. The blue and red lines represent the most recent versions of Leopard.
