Nancy and the Mysterious Case of the Undefined Object

A few months back, I switched my mobile app development from the IOS environment (apple) to non-native JavaScript. I'm enjoying coding a great deal more than I was with IOS, but still.... debugging is hard.  

Oddly enough debugging is what I missed most when I was off pursuing teaching as my interim career. Missing the looking-for-clues part of programming is what I missed most about not coding.

So when my husband replied with his usual 'Oh, I'm sorry.' response to my description of my morning's work I explained to him. You never expect the detective to get it figure out on her first shot. If she did the book just couldn't go on for 250 pages!

An App for That: The Pedestrian's Rope Bridge App (Priority Street Crossing)

Do you find it so unfair that walkers have to waste precious minutes waiting to cross major boulevards when we're out for a walk?

Hey! Who is not wasting the planet's fossil fuels here? We walkers deserve a special right of way, when it comes to crossing busy streets. At the push of button, and not the one on that light pole that shouts "Wait" until it's darn good and ready to give me 8 seconds to get across a six lane highway, I should be able to get immediately and safely across any intersection I choose. 

And now I can.

With the Pedestrian's Rope Bridge App, the walker rules! With one quick swipe of a finger on my iPhone, a rope bridge comes shooting out of the bottom of my mobile device, springs up from my feet, arcs over busy streets, and let's me down safely on the other side of the road. It's neat, it's easy to use, and it's guaranteed to make others wonder, "Why am I driving when I could be walking?" 

Once I've crossed the street, another quick gesture on my phone and the bridge springs back into the base of my phone. Remember those retractable metal tape measures we used in the old days before we calibrated everything with laser beams? Yup, it slips back in pretty much the same way.

You can call this app a fantasy if you want, but just give it a couple of years...

An App for That! Plumber's Friend App Saves the World

I'm in the final throes of finishing up my Edgewood Secrets iPhone app. Today I'm beginning the job of submitting it for approval. 

I created Edgewood Secrets as a companion for folks hiking at Edgewood Nature Preserve, here in the San Francisco Bay Area of California. I hike at Edgewood quite regularly and I'm also a wildflower docent there.  In the app, I share stories of different experiences I've had in the preserve, as well as tales I've been told by other folks. 

As great as it is (and I should know!) Edgewood Secrets is a pretty straightforward app. Like most developers, I have plenty of plans for other mobile device creations along similar lines. It's not challenging coming up with ideas for great apps, it's challenging doing the work involved to get those ideas implemented. And despite the typical claims of the folks who create the software development environment I use, the technology isn't easy.

The ideas, however, spin away. I keep lists of course. Yes, I have lists everywhere on my laptop, and iPhone. Most of them are quite practical. It's a matter of getting on with them. Then there are those....hummmm what can I call them? Speciality apps, I guess.

One of my favorite specialty app plans is the Plumber's Friend App (PFA).   Here's the user experience I envision...

Have you ever been brought up short while speeding out the door - your laptop zipped into it's case, your lunch packed in that outside pocket (so the avocodo doesn't mash onto your keyboard),  your teeth (hopefully) brushed, your hair at least looking brushed, and shoes that more or less match on both feet - to the call of "Mom, the toilet's backed up again!". Why oh why, you wonder for the hundred thousandth time, are we stuck with the retro fifties, only-one-bathroom apartment model? (Surely it couldn't be affordability.)

What to do? The metro isn't going to wait while you get out the plunger. And the folks at work aren't going to keep a chair warm for you in the 8:15 meeting. In fact... if you arrive late at that meeting, you're going to get volunteered to put on the Friday night Management Achievement Awards banquet. How fun will that be in addition to getting your already-behind-goal project fully functional before the project status meeting next week?

PFA to the rescue. You simply pull out your iPhone - now which pocket did you put that in? - aim it vaguely at the wall, and with one swipe of your finger you launch the Plumber's Friend App. PFA does it all for your. As you streak along making a beeline for the metro station, you hear from the open window above, that blessed sucking of air, a mighty flush, and the noise of your teenage daughter cheering (I did say this was pure fantasy, right?) as PFA once more saves both the world, and your day.  

I haven't quite identified the foundation kit classes I'm going to need to write this app. Perhaps they haven't quite yet been created. But you can be sure once they're out there, you'll be seeing a new app in the store. 

Do you think I'll be able to charge more than 99 cents for it?
