Growing Up Alexa

A few months ago, I wrote about how Alexa and Google Home are used in our house. In my experience, these devices are a better way for kids to use the internet than a mobile phone. A phone becomes an extension of a person, isolating her from the group. Interacting with Alexa is more of a family activity with Alexa acting like another person in the room.

Some people think it’s odd to treat Alexa humanely. As a machine, she doesn’t have any feelings. But think about the way we refer to Alexa. It feels more natural to refer to Alexa as a “her” than an “it” because that’s the way we interface with her. And if we interface with her as a person, we should be polite and say please and thank you. Continue reading “Growing Up Alexa”

How to be Happy — Yale’s Most Popular Class

This year Professor Laurie Santos created Yale’s most popular class of all time. The class is titled Psychology and the Good Life but it’s really a course on how to be happy both in the short and long term. I was excited to hear that Yale was offering the course but even more excited to see that the class is available online. While there’s little I hadn’t heard before, it did a great job of focusing me on what’s important and helped me get into the practice of being happier.

These are a Few of My Favorite Words

To start with I found an amazing etymological podcast called The Allusionist by Helen Zaltzman. She has some great episodes on cursing [NSFW], Mountweazels (fictional words used in dictionaries for copyright purposes), portmanteaus (combination words like “brunch”) and eponyms (words named after people). She also had a great TED talk on how the letter i got a dot on top of it. Continue reading “These are a Few of My Favorite Words”

Why Do People Think That Wearing a Hoodie to Work is a Status Symbol?

I spotted a technology executive walking down the street. He used to wear expensive tailored suits. Now he’s coming to work in high-end jeans and a polo shirt. Then it hit me. Jeans and a turtleneck or jeans and a polo shirt (or really jeans and anything) is the new innovation wardrobe. On one level, it makes sense because everyone wants to dress like Steve Jobs. But when you dig a little bit deeper, using Silicon Valley clothes as a status symbol doesn’t make any sense at all.  Continue reading “Why Do People Think That Wearing a Hoodie to Work is a Status Symbol?”

How Strawberry Ice Cream Got the Short End of the Stick

In the class The Science of Well-Being, Professor Santos focuses on how we often look at our happiness not in an absolute way but by comparing ourselves to those around us. These thoughts about absolute vs. relative comparisons got me thinking about strawberry ice cream.

Whenever I eat strawberry ice cream, I think is pretty wonderful. It’s light, sweet, and just a little bit tangy. If I like strawberry ice cream so much, why am I surprised at this fact every time I eat it. I feel like I’m carrying some sort of bias against strawberry ice cream — but why?

Reframing Bad News to Inspire the Team

A leader’s job is to inspire their team. This is easy when things are going well. A good leader can keep morale up even when there’s bad news. But a great leader can find a way to use the bad news itself as inspiration.

I remember two years ago working at a financial services firm in an innovation group. John was the leader of the group. He started out the weekly team meeting by saying, “We got some news over the weekend. We redid our projections for the project launch and instead of the $50 million that Tony projected, we are only going to make $5 million in the first year.”

The Mother-in-Law’s Guide to Software Testing

This is part of my Mother-in-Law’s Guide to Technology. My Mother-in-Law is a very smart woman even if she isn’t a “computer person.” The goal of this series is to take some big and treacherous sounding ideas and bring them down to earth.

Dearest Mother-in-Law,

Remember when you had kids and you told them to do stuff. And remember how they used to do what you told them but that wasn’t always what you intended them to do? Well, that’s the way computer programs work.

Just like kids, computer programs will do what you tell them, but beyond that, all bets are off. They don’t do anything that directly contradicts what you said but that doesn’t mean they’ll do what you want them to do. Continue reading “The Mother-in-Law’s Guide to Software Testing”

How I (Re-)Built My Favorite T-Shirt

Read in the voice of the Mission Impossible announcer: This t-shirt was originally created as a protest against US Export laws. Until 2000, US export law considered the computer code on the shirt as a “munition” that should not be exported from the United States or shown to a foreign national. Your mission, if you choose to accept it, is to re-create this shirt.

The T-Shirt

When I was at the GEL conference in 2016, I met a woman who worked for the website Design a Shirt. We started talking about the most creative t-shirts we’d ever seen. This brought me back to the late 1990s when I discovered one of the most innovative shirts ever created — a t-shirt that the US government classified as a weapon.

Oddly Necessary Background on US Encryption Export Policy

This t-shirt was created as a protest against the way the US government was treating the export of encryption (i.e., secret codes).  Until 2000, US government considered encryption as a munition that should not be exported from the United States or shown to a foreign national.

It seems a little odd that software that’s embedded in everyone’s iPhone today used to be illegal to export. Put in historical context it makes more sense. For centuries, encryption was used to allow military organizations to pass messages. The most famous of these devices was the German Enigma machine from World War II. The capturing of an Enigma machine allowed the allies to break the German codes and win the war.

The German Enigma Encryption Machine

In the 1990s, US government policy still hadn’t veered from this idea. Any secret codes that were used by foreign governments should be breakable by the US government without too much effort. At the same time, encryption was becoming a critical part of internet communications. The issue here was that the exact same technology that was powering the internet was also used to send secret government and criminal communications.  This led to internet browser companies like Netscape to create two different browser versions. They distributed a “strong encryption” that was only available in the US and a “weak encryption” that could be exported everywhere else.

Some internet activists were upset about weak encryption. You see something similar in the fight today between the US government and Apple on the right to be able to break into criminals’ iPhones. The government was claiming that it was dangerous for people to have secrets that the government couldn’t see if they needed to. The protesters were saying weak encryption creates a weak internet.

Making The T-Shirt

This is where t-shirts make their appearance. Some encryption advocates had the idea to create a very small but strong encryption program whose entire code could be put on a t-shirt. Therefore, anyone wearing this t-shirt to a foreign country or even seen by a foreign national would be exporting a munition would be breaking a law.

That’s a creative t-shirt! I really wanted one. However, I ran into two problems. First, most of the t-shirts are pretty ugly. Secondly,  since the law changed in 1999, the demand for this t-shirt has plummetted and it’s no longer sold.

With no one making these t-shirts anymore, I needed to do it myself. First, I needed to find a design of the shirt that I really liked. Second, I needed to find a way to print it.

For the design, Vipul Ved Prakash made a wonderful version of the computer code in the shape of a dolphin.  The company ThinkGeek printed the shirt back in the 1990s.

So then I needed to make the t-shirt. Most t-shirt printers want you to buy in bulk but Design a Shirt works well for one offs.  Making the shirt is easy. I just uploaded the image and choose a shirt type. The benefit to making your own shirt is you can pay the $5 more for a super premium quality shirt. I also chose to pay another dollar to print the dolphin in blue. If you want to print the shirt, it’s still available on the Design a Shirt site.

Here’s the Final T-Shirt
And Here’s the Image I Used in the Shirt

I really love this t-shirt and proud I re-created it. The world needs more of these shirts — clever, interesting and pretty designs that tried to change the world. I thought someone would recognize it when I wore it; however, even at technology events, I haven’t met anybody who mentioned it. I even added the last paragraph to the shirt to explain it to people. If you want to print one for yourself, it’s still available online.

Note: In the unlikely event you’d like to learn more, there’s a good Wikipedia article on US encryption policy that even mentions the t-shirt.
