I needed some mental floss one night in New York last week when I was having trouble sleeping so I read Playing for Pizza: A Novel. My mom had recommended this one – I can’t remember why – but I usually read whatever she recommends. Put it in the “good son” category (although she helped me develop my love of reading and she’s almost always on target with recommendations for me.)

I grew tired of John Grisham and his legal thrillers over a decade ago. But I always enjoyed his writing so it was fun to dig into something completely different. I love Italy, pizza, and food, so that made sense. Football, however, is low on my list of things I care about. I decided to blow off caring about the football stuff and just get lost in the book.

Grisham has always written a book I can read in one sitting. I turned off my iPad at about 1:30am NY time and smiled. The Italy stuff was good. The pizza stuff was good. The food stuff was good. And the football stuff was even good.

If you are looking for something light, clever, engaging, and written in typical fast moving Grisham style, grab it. Solid mental floss.

Last week TechStars London was approved for the UK Entrepreneurs’ Visa. If you are accepted to TechStars London, you now automatically get the UK Entrepreneurs’ Visa.

The approval will allow TechStars London teams from outside of the EU to work in the UK for up to three years. After the three years, they can apply to extend their stay by a further two years if they want to continue living here.  Furthermore after three years teams have the right to apply for permission to settle in the UK if their business has created at least 10 new full-time jobs in the UK. Partners and children of the teams can also apply for settlement.

As you likely know, I’ve been advocating for something like this in the US since 2009. Fred Wilson wrote a good post yesterday on the current state of Immigration Reform in the US which includes a summary of the recently introduced comprehensive immigration reform bill. It includes a bunch of things I’ve advocated for since I started paying attention to this in 2009, including a Startup Visa and a STEM Visa (or – in my language – “a Visa stapled to the diploma of every college graduate.”)

I hope we finally get something done in the US. In the mean time, Canada and the UK are being very forward looking about their immigration policy in the context of immigration. The US doesn’t have a monopoly on innovation – it’s time for us to get our act together on the immigration front. In the mean time, TechStars London applications are open!

I’ve been reading a lot more lately – mostly on the weekends – but I’m getting back into a good book rhythm. I can feel it helping my brain and my soul – I’ve always been a huge reader and when I go through phases where I’m not reading something is clearly off.

The second of the three books I read this weekend was Worm: The First Digital World War. It was crap in your pants scary in that real life, cyberwarfare way. If you’ve ever been on the receiving end of a DDOS attack, you have to read this book.

The author, Mark Bowden, does a great job of telling the story of the Conficker worm in English. Even if you aren’t technical, you’ll enjoy this book as it borders on cyberthriller while telling a real live story that unfolded over several months in late 2008 / early 2009. I was vaguely familiar with Conficker (as in I remember the hoopla about it) but I didn’t know the backstory.

Now I do. And it’s terrifying. And amazing. At many different levels.

We continue to visibly see the impact of physical war and terrorism all the time. But we are just beginning to see cyberwarfare and cyberterrorism. On one of the participants, Paul Vixie, is quoted near the end brilliantly in his “one command away from catastrophe” rant.

These problems have been here so long that the only way I’ve been able to function at all is by learning to ignore them. Else I would be in a constant state of panic, unable to think or act constructively. We have been one command away from catastrophe for a long time now. . . . In a thousand small ways that I’m aware of, and an expected million other ways I’m not aware of, the world has gotten dangerous and fragile and interdependent. And that’s without us even talking about power grids or the food stocks available in high population areas if rail and truck stops working for a week. AND, in a hundred large ways that I’m aware of and an expected thousand I don’t know of, ethically incompatible people out in the world have acquired and will acquire assets that are lethal to the industrial world’s way of life—criminals and terrorists using the Internet for asymmetric warfare is the great fear of our age, or at least it’s my great fear. But I’ve lived with it so long that I have lost the ability to panic about it. One day at a time, I do what I can.

We are just at the beginning of this.

On Digital Sabbath #5, I read Tech and the City: The Making of New York’s Startup Community. I got through half of it on my flight home from New York on Saturday morning; the balance laying on the couch next to Amy on Saturday evening.

I gave a talk with Alessandro Piol on Tuesday night at the Apple Store on Prince Street that was sponsored by the Women Innovate Mobile accelerator. We had a fun hour long talk with Q&A, a lot of it about Startup Communities. I hadn’t read Alessandro’s book in advance (but I did have it on my Kindle) so I was inspired to gobble it down this weekend.

It was excellent. If you are involved in the New York startup community, this is a must read book. If you are interested in startup communities in general, it’s a substantive history and current explanation of what is going on in New York.

One thing that jumped out at me that Alessandro segmented the New York startup community into six neighborhoods.

• Flatiron / Union Square: The Heart of Silicon Alley
• The Meatpacking District and Chelsea: Tech and the City
• East Village, Soho, and Lower Manhattan: The Boheme of the Third Millennium
• Brooklyn: The Do-It-Yourself Revolution
• The Bronx: Sunshine Fortress
• Long Island City in Queens: The 3D Generation

If you’ve heard me talk about startup communities, you’ll recognize this as the same approach I take when talking about larger communities like New York, the Bay Area, Los Angeles, and Boston/Cambridge. In these cases, the startup neighborhoods look similar to a startup community like Boulder – there is an incredible density of startup activity in a small geographic area. In a city like New York, rather than having everything in one place, you have a series of neighborhoods that have this entrepreneurial density, but are connected together to form the overall startup community.

I experience this all the time in New York. But I got a new taste of it on Thursday. I went to Brooklyn after an early meeting near Greeley Square Park. I started off at 20 Jay, saw NYU Poly Incubator, went for a long walk around DUMBO with Charlie O’Donnell, had an awesome lunch with Chad Dickerson (Etsy CEO), and then walked to MakerBot and hung out with the team there for a while. I did all of it on foot – including the back and forth from Manhattan.

The last third of the book is forward looking, talking about where things can, and are, going in the New York startup community. Finally, while there are plenty of VCs and government folks involved, it’s very clear that this is an entrepreneur led phenomenon, and Alessandro does a good job of balancing all the players.

Oh – and Digital Sabbath #5 was excellent. Even though I was on a plane for four hours, I woke up Sunday once again feeling refreshed and as though I had a weekend stretching out in front of me.

Teaching kids to program is not an easy task – their attention span is short and what they are able to accomplish in a brief period of time is often uninspiring which results in them losing attention quickly.

Robots help a lot with this!

The Orbotix team has turned their Sphero into a fantastic programming aid to introduce coding to kids as young as 4th grade.  In about an hour kids will be commanding their robot to drive geometric patterns while also learning a bit about angles, degrees, time and distance calculations, loops and conditional branching. If your my age, you might remember Logo and turtle graphics. It turns out to be really cool to toss a robot into the mix, instead of just a computer screen.

Coding is done via a simple app on either Android or iOS devices and sent to the Sphero via Bluetooth.  The younger kids learn to program using a simple scripting language developed by Orbotix called MacroLab – the older kids learn BASIC which Sphero can interpret to do some complex tasks.

Orbotix is hosting a “Sphero Rangers” event at the Google offices here in Boulder this Saturday from 11am to 2pm.  Robots and programming devices will be provided – but bring your smartphone if you want to use your own.  Attendees will also be able to get a Sphero at a discounted price.
