AT&T opens 2G/3G to VoIP

With a landmark decision, AT&T will let me and some other 4+ million users initiate Skype calls from the iPhone without being limited to Wi-Fi hotspots.

I expect that other carriers will follow suit. It’s a tipping point for the mobile Internet. It’s a boon for the smartphone segment.

In turn, some new applications will soon come out and seize the opportunity. I recently blogged about the wheel of innovation. Today, I saw that wheel turning a notch.

UPDATE. Make that two notches with the announcement of the strategic Android partnership between Verizon and Google.

Scaling … Mt. Hamilton

I’m taking a break from the buttoned-up posts on ICT scaling and write about people that scale, for a change. I want to share the joy of my bicycle ride up to the top of Mt. Hamilton. I had the pleasure to do this (and the many weekend rides that preceded) alongside my long-time friend Enzo. This summit was a first for both.

Mt. Hamilton is one of the great rides in the South Bay, if not the greatest. We left the car at the intersection of Alum Rock and Mt. Hamilton Rd, San Jose, CA. From there, it took us 3 hours to climb to the summit and 1 hour to make it back.

The long, gentle climb helped us to pick up a good rhythm, without any coup de grace lurking at the next turn of the road. The last 4 miles were the toughest ones because legs felt quite tired and heavy by then. After the bridge, I was on the 28t final position cog most of the time (but never ever on the granny gear!), with short stints on the 25t whenever the road eased a little bit. I created this elevation chart compliments of Bike Route Toaster (note: it’s meters on the Y-axis and kilometers on the X-axis).

At the summit, the view is breathtaking. The Lick Observatory is a treat in its own right. We joined a (free) tour of the dome. Very engaging. For sure, the hosts up there know their crowd! Please remove the shoes with cleats before stepping in. Please don’t feed damp bills into the vending machine ;-)

On the way back, we made a few deliberate stops to keep safe and alert. My bike has me pretty low for aerodynamics’ sake, thus I had to shift weights and rest arms and neck every so often. The rustling noise of the wind was so loud that I could not quite hear cars approaching from behind. I had noticed this in preceding trials and bought a rear view mirror that attaches to the drop-down handlebar. The last 3-4 miles before returning to sea level, the road’s pavement turned wonderfully silky smooth on us. It felt as we were welcomed back in style, after a most enjoyable and rewarding ride.

The pictures of this climb are posted here.

And the iWinner is…

It’s Academy’s night and is a good time for a geek to retrospect on the coolest 2008 iPhone applications:

  • My pick: Trailguru. I’m an avid road cyclist and take the iPhone with me to log the stats of my short runs, like this one or this one or this other one. Excellent use of the GPS. The two chief shortcomings are the battery life and the UI. In spite of a few dead-on-arrival cases, I still log the iPhone and run Trailguru on all my runs;
  • My wife’s pick: Hangman. Old wine in a new bottle. When it’s set on hard words, the entertainment is warranted. It can keep everybody in the car entertained;
  • Children’s pick: Monkey Ball was love at first sight. They have yet to move on. Distant runner ups include: Audi A4, iTicTac, Labyrinth, and Koi Pond.

One day, I will dig into Objective-C and dust off pound defines (as in #define) to make one of my own!

Wikipedia for my children

When talking about kids that accidentally stumble upon improper content on the Internet, a colleague at work mentioned that he only lets his children perform searches within Wikipedia. This gave me an idea. How about setting the browser’s homepage such that the browser starts on wikipedia and displays a new article every time it is started? It wasn’t long before I found that this URL http://en.wikipedia.org/wiki/Special:Random does the trick. I put it into the browser’s configuration and voila, it’s the gift that keeps on giving. Before playing games or going to Club Penguin, my children must read the wikipedia page displayed at startup and write a one-paragraph summary on the topic that they have just stumbled upon. Don’t like that one? Just hit the home button!
