Introducing Minipad

MinipadI am happy to announce a new app I’ve created for iPhone and iPad. It’s called Minipad and it’s a super-simple text editor for people of all ages to create stories and notes or just play with words and letters. Minipad is available now for free on the App Store and you can learn more about what makes it different on the Minipad homepage.


I am thankful to have had the opportunity to attend Apple’s World-Wide Developer Conference in San Francisco this past summer. The conference was very fun and intellectually stimulating. (Side note: it was also exciting to see and meet some tech-world creators I greatly admire.)

Throughout WWDC, there was a prominent focus on Swift, especially since version 2 of the language was announced in the keynote. As one might expect, WWDC can be very inspiring for app developers. Since I hadn’t yet had the opportunity to use Swift at my day job, I decided to learn to use the language on a personal side project and that is where Minipad started.

Of course, the app itself required more work than I originally thought it would. Writing it in Swift (first 1.2 and more recently 2.0) has been delightful. I am very pleased with how the app turned out and I hope people will enjoy using it.


As a dabbler in computer graphics and design, Minipad was a nice excuse to stretch my Sketch muscles with version 3 of the amazingly powerful tool.

How I Became a Software Developer

Developing software requires a wonderfully unique blend of math, science and art. Some call what we do a craft which rings true to me. All the great developers I’ve known treat everything they do with the respect an artisan would.

I sometimes worry that the modern day ubiquity of easy-to-use computers, now often through mobile and wearable devices, is making it increasingly hard to attract the next generation of developers. While developing software applications is becoming easier in many ways, there are also more layers of abstraction. While it’s easier to pick up and use a computer today, it’s also much harder to get a glimpse behind the curtain — or even a sense that there’s a curtain at all.

I consider myself lucky that I discovered my calling early in life — a true passion that also handily pays the bills. Who could ask for more in a career? Recently I’ve been thinking back on what it took for me to realize this path that I’m on. I’ve narrowed down my primary sources of inspiration into to three separate phases through my formative years.

Phase 1: Childhood Inspiration

One of my earliest memories of impressive technology was a bright red digital Timex Snoopy watch that my parents got for me on a road trip. I was probably 5 years old and this was my first watch. This device really made an impression on me because when you pressed a button, there would be a short animation of Snoopy pitching a baseball. On a watch! To be animated whenever I wanted!


In the mid ’80s, I became quite obsessed with the Casio Databank watch. Yes, the calculator watch that I’m sure many high-school kids were made fun of for wearing — thankfully my elementary school peers didn’t seem to notice or care. Although a fine feature, it wasn’t the calculator that really impressed me on this watch, it was the data storage feature — type in and access 50 short pieces of arbitrary text. This coupled with the nifty LCD display that was capable of scrolling truly readable letters and numbers across the face. I could even play around with this wonderful device during class!

I never really got into watches but it now seems clear that these two watches were quite influential in making me passionate about technology in general.

Also around this time I started being exposed to video games. My grandfather, always quite the techno-enthusiast, purchased a TI-99/4A computer. I never quite got into programming that thing (for more than 20 minutes anyway) but it was really fun playing some of the cartridge games on it including TI Invaders, Parsec (my grandmother’s favorite) and the brutally challenging Car Wars.


My daycare in grade school had a Colecovision which was totally awesome. And then one day my mom amazed me at the local K-Mart by purchasing the Nintendo Entertainment System. This thing was simply wonderful and captured so much of my attention for years. That passion for gaming eventually led to countless hours spent in various arcades and plenty of portable gaming too.

Phase 2: Teenage Tinkering


The next phase of my tech-odyssey revolved around more general purpose computers. My dad became particularly interested in the new personal computing revolution after he read an article stating basically that, as of Windows 3.0, PCs were finally affordable and easy enough to use for everyone. So he picked up a IBM Personal System/2. This thing seemed fairly weird, even at the time: super clicky keyboard, ugly beige color and loud and slow (compared to my Nintendo anyway). My dad used it for keeping books and I used it for, well, everything else. I learned the ins and outs of MS-DOS, played with the Windows 3 UI and pushed this machine to play games. It didn’t have a “real” sound card and mostly bleeped and blooped through the so-called PC speaker. I was absolutely amazed when the delightful Another World managed to play real music and sound effects.

My dad also encouraged me to take a Keyboarding class in high school and got me a “game” for the IBM, Mario Teaches Typing. Mario didn’t help much but the class was super useful. Can you accurately hit the numbers row without looking?

My next machine was a 386 clone and although it was faster and better, the kicker was the Sound Blaster multimedia kit to go with it. That set had a CD-ROM drive and some amazing Lucasarts games (Secret of Monkey Island, Loom) and I spent many hours tinkering with games that were in some ways even better than the ones I adored on the Nintendo.

I also did a bit of BBS-ing with the PS/2 which had a built in 2400 baud modem and then around ’94 got a Sportster so that I could properly connect to the internet. I can still remember fretting over the monthly fee (around $20 I think) for dial up internet. “But what will I use it for?” I can remember seriously thinking. The answer was: IRC, News groups, FTP sites and of course, the good old World Wide Web. This was before most web pages had background colors or images (things were very gray). I remember once buying a magazine that simply listed and described various web pages one might want to visit. I think I visited each of the websites that were in that magazine.


One important thing that the Net brought to me was the demoscene. I was blown away by everything produced by the Finnish group Future Crew and had to download all of their PC demos and tracker music mods. These programs truly inspired me to dabble with music tracking and graphics programming late into the night.

Basically, all of the time I spent with these two machines really opened my eyes up to what computers were capable of — including and well beyond gaming.

Phase 3: Formal Studies

My high school has changed a little since I attended

I am lucky that my high school, North Toronto CI, mostly known for it’s music program had excellent computer science and mathematics programs too. I became curious about CS in 10th grade when my buddy who was fast-tracking — taking the class a year earlier than recommended — let me browse through his textbook one day. The next fall I decided to give it a shot and that led to three great years of CS in high school.

These classes were taught with a sincere passion by John Carter and Gerry Heffernan. The 11th grade class was intro to programing with Pascal, 12th grade was C with more advanced fundamentals and 13th grade was intro to C++ and OO along with independent studies. (Yes, we once had grade 13 in Ontario — a fine thing to have had).

I fondly remember spending class time discovering and playing Nibbles, a game that shipped with MS-DOS. I was also quite proud of my two big grade 13 projects. One was a fractal screensaver that did color cycling on fractal images I had generated and the program even stayed resident in memory. The other was a space shooter, the only game I’ve ever bothered writing. (Surprisingly and thankfully, I quickly learned that developing games was not my bag.)

A local software entrepreneur was looking for a few interns and reached out to my CS teacher. A buddy and I interviewed and we got part time jobs after class. This job was completely awesome. I got to learn some Windows programming using Visual Basic and I was able to play with databases (MS Access). It paid $8 an hour. Plus, after the boss went home the younger guys played hours of multiplayer Doom II on the LAN.

By the time I was applying to Universities, I was absolutely sure of my major. This confidence helped me get into my first choice, the University of Waterloo, arguably the top CS undergrad program in Canada. While I can’t say I loved most of my college courses, I did really enjoy the CS and some of the math classes I took. Some of my favorites were Graphics (SGI O2s in the darkened, private lab!), Concurrency, Compilers, Operating Systems, and Chaos & Fractals.


Not only did the University of Waterloo develop the first Math faculty in North America, but it developed the world’s largest co-op work program, which was invaluable for me. These work terms helped me pay for my degree and gave me a strong resume that ensured my first full time job. Because of all of this rich work experience I was sure that I was in both the right major and the right career.

How I Bluetooth Podcasts in My Car

The iPhone is an amazing podcast consumption device. I absolutely love how you can continue listening where you last left off with no fuss. Here is the exquisitely minimal walking-around listening workflow I use:

  1. Plug in earbuds
  2. Click play on the earbud remote
  3. Listen
  4. Unplug earbuds

Notice that this is the bare minimum number of physical steps to achieve what you’d want and you never need to take the iPhone out of your pocket. Pretty great.

My current buds

I wanted to continue listening to my podcasts in the car, preferably not needing to remove the phone from my pocket. Ideally it would be:

  1. Turn on ignition
  2. Press play on car dashboard
  3. Listen
  4. Turn off ignition

Car Bluetooth Solutions

I’m not sure how many new cars have built-in bluetooth audio but my wife’s 2009 doesn’t. My beloved 2002 RSX doesn’t even have an audio line-in so I needed something extra. It took me three tries until I found a solution that worked well for me and it wasn’t easy to find reviews online that covered the things I cared about. I hope these review notes prove useful to anyone interested.

(Note: all of these solutions support hands-free Bluetooth calling but I rarely make or take calls in the car so I won’t go into that in these reviews. I will mention that phone calls are okay in solutions (1) and (2) and work quite well in solution (3) given the dedicated wired mic and superior audio output quality.)

1. GoGroove

The GoGroove is a fairly well recommended device that plugs into your cigarette lighter (do the kids still know that’s what they were once for?). It uses an FM radio signal to pipe the audio to your car stereo that it fetches via Bluetooth.

1st try: GoGroove

It’s long and kinda ugly but some might like how the pliable stalk allows it to come right up to where you’re used to reaching. I’d much prefer it to be smaller and less conspicuous. The main pros for it are that you can play/pause directly from the GoGroove and the reception is decent (but not great — most likely true for any FM-based bluetooth solution).

Unfortunately mine simply stopped working after about a week (YMMV) so I returned it and decided to try something else.

2. Satechi

I tried the Satechi next which is a similar device but much smaller and sleeker. Unfortunately the reception was noticeably worse than the GoGroove and it required daily physical adjustment to get the audio quality to be bearable. Also, it doesn’t have the ability to play/pause the audio directly from the device so you’ll need to fiddle with your phone after starting the car. Both of these flaws are deal breakers.

2nd try: Satachi

3. JVC KD-R810

I needed to bite the bullet and get a whole new class of solution. Last August, after much research, I decided on the JVC KD-R810 in-dash Bluetooth receiver (since superseded by the KD-R900). This was obviously a bigger deal since I needed to replace the stock stereo which meant getting a wiring kit and hiring someone do do the work. (I’m not a DIY car enthusiast so I went to Car Toys for this – their rate was good and they had the proper wiring harness in stock. They did a decent job.)

3rd try: JVC

The benefits were massive: no more FM radio signal — the audio quality is amazing. Also, playback can be initiated from the dash so I achieved the ideal listing workflow mentioned at the top. Once you turn on the car it takes about 5-10 seconds to pair with the iPhone and then you’re good to go (there is an on-screen indicator when it’s ready). Also nice is that the unit has something like 30 different light colors so you can match your interior dash lighting pretty accurately.

The only big con is that there’s no (obvious) way of pausing playback and it’s a little strange that you’re to press “menu” to start the audio playback. But these both aren’t really that noticeable in practice.

Overall I’m very pleased with the JVC and would recommend it.

Podcast Apps

I was eager to use Instacast, an alternative to the iPhone’s “Music” app, mainly to take advantage of its ability to fetch new podcast episodes while I’m out and about. The app is cool but unfortunately due to the way the iPhone manages memory, I couldn’t achieve my optimal listening workflows mentioned at the top. At the end of the workday I would get in my car to go home, press play and start listening to an entirely different podcast — the one queued up in the Music app.

It turns out that after some time using the phone for other activities, iOS would kill the Instacast app so that starting up the audio initiates the default Music app (which I guess never gets terminated by the OS). This was annoying enough that I’ve gone back to using Music and dealing with iTunes again (which thankfully is mostly automatic since the advent of wireless syncing).

Siri in the Car

It’s worth noting that you can invoke Siri on an iPhone 4S by initiating a voice dial through the JVC with a couple of button clicks. Then you can try to say anything (like “Play The Talk Show”) which is pretty neat — when it works. I guess the voice audio quality of the JVC hands-free system isn’t good enough for Siri to always, or even usually, just work.

Update 3/21/2013: Siri has drastically improved since I wrote this post. I rarely need to ask for a podcast or album more than once.
