The Yo Charm. It's that simple.

It's that simple.

It was about 4pm on Friday afternoon, when I had just about wrapped up everything I absolutely needed to do for the day, and I decided to kick back and have a little fun with the remainder of my work day.

 It's now 4:37pm on Friday, and I'm now done.

Done with what?  The Yo charm, of course!

The Internet has been abuzz this week about the how the Yo app received a whopping $1 million dollars in venture funding.  (Forbes notes that this is a pretty surefire indication that there's another internet bubble about to burst...)

It's little more than the first program any kid writes -- hello world!

Subsequently I realized that we don't really have a "hello world" charm.  And so here it is, yo.

$ juju deploy yo

Deploying up a webpage that says "Yo" is hardly the point, of course.  Rather, this is a fantastic way to see the absolute simplest form of a Juju charm.  Grab the source, and go explore it yo-self!

$ charm-get yo
$ tree yo
├── config.yaml
├── copyright

• The config.yaml let's you set and dynamically changes the service itself (the color and size of the font that renders "Yo").
• The copyright is simply boilerplate GPLv3
• The icon.svg is just a vector graphics "Yo."
• The metadata.yaml explains what this charm is, how it can relate to other charms
• The README.md is a simple getting-started document
• And the hooks...
• config-changed is the script that runs when you change the configuration -- basically, it uses sed to inline edit the index.html Yo webpage
• install simply installs apache2 and overwrites /var/www/index.html
• start and stop simply starts and stops the apache2 service
• upgrade-charm is currently a no-op
• website-relation-joined sets and exports the hostname and port of this system

The website relation is very important here...  Declaring and defining this relation instantly lets me relate this charm with dozens of other services.  As you can see in the screenshot at the top of this post, I was able to easily relate the varnish website accelerator in front of the Yo charm.

Hopefully this simple little example might help you examine the anatomy of a charm for the first time, and perhaps write your own first charm!

Cheers,

Dustin

Elon Musk, Tesla Motors, and My Own Patent Apologies

It's hard for me to believe that I have sat on a this draft blog post for almost 6 years.  But I'm stuck on a plane this evening, inspired by Elon Musk and Tesla's (cleverly titled) announcement, "All Our Patents Are Belong To You."  Musk writes:

Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters. That is no longer the case. They have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology.

When I get home, I'm going to take down a plaque that has proudly hung in my own home office for nearly 10 years now.  In 2004, I was named an IBM Master Inventor, recognizing sustained contributions to IBM's patent portfolio.

Musk continues:

When I started out with my first company, Zip2, I thought patents were a good thing and worked hard to obtain them. And maybe they were good long ago, but too often these days they serve merely to stifle progress, entrench the positions of giant corporations and enrich those in the legal profession, rather than the actual inventors. After Zip2, when I realized that receiving a patent really just meant that you bought a lottery ticket to a lawsuit, I avoided them whenever possible.

And I feel the exact same way!  When I was an impressionable newly hired engineer at IBM, I thought patents were wonderful expressions of my own creativity.  IBM rewarded me for the work, and recognized them as important contributions to my young career.  Remember, in 2003, IBM was defending the Linux world against evil SCO.  (Confession: I think I read Groklaw every single day.)

Yeah, I filed somewhere around 75 patents in about 4 years, 47 of which have been granted by the USPTO to date.

I'm actually really, really proud of a couple of them.  I was the lead inventor on a couple of early patents defining the invention you might know today as Swype (Android) or Shapewriter (iPhone) on your mobile devices.  In 2003, I called it QWERsive, as the was basically applying "cursive handwriting" to a "qwerty keyboard."  Along with one of my co-inventors, we actually presented a paper at the 27th UNICODE conference in Berlin in 2005, and IBM sold the patent to Lenovo a year later.  (To my knowledge, thankfully that patent has never been enforced, as I used Swype every single day.)

QWERsive

But that enthusiasm evaporated very quickly between 2005 and 2007, as I reviewed thousands of invention disclosures by my IBM colleagues, and hundreds of software patents by IBM competitors in the industry.

I spent most of 2005 working onsite at Red Hat in Westford, MA, and came to appreciate how much more efficiently innovation happened in a totally open source world, free of invention disclosures, black out periods, gag orders, and software patents.  I met open source activists in the free software community, such as Jon maddog Hall, who explained the wake of destruction behind, and the impending doom ahead, in a world full of software patents.

Finally, in 2008, I joined an amazing little free software company called Canonical, which was far too busy releasing Ubuntu every 6 months on time, and building an amazing open source software ecosystem, to fart around with software patents.  To my delight, our founder, Mark Shuttleworth, continues to share the same enlightened view, as he states in this TechCrunch interview (2012):

“People have become confused,” Shuttleworth lamented, “and think that a patent is incentive to create at all.” No one invents just to get a patent, though — people invent in order to solve problems. According to him, patents should incentivize disclosure. Software is not something you can really keep secret, and as such Shuttleworth’s determination is that “society is not benefited by software patents at all.”Software patents, he said, are a bad deal for society. The remedy is to shorten the duration of patents, and reduce the areas people are allowed to patent. “We’re entering a third world war of patents,” Shuttleworth said emphatically. “You can’t do anything without tripping over a patent!” One cannot possibly check all possible patents for your invention, and the patent arms race is not about creation at all.

And while I'm still really proud of some of my ideas today, I'm ever so ashamed that they're patented.

If I could do what Elon Musk did with Tesla's patent portfolio, you have my word, I absolutely would.  However, while my name is listed as the "inventor" on four dozen patents, all of them are "assigned" to IBM (or Lenovo).  That is to say, they're not mine to give, or open up.

What I can do, is speak up, and formally apologize.  I'm sorry I filed software patents.  A lot of them.  I have no intention on ever doing so again.  The system desperately needs a complete overhaul.  Both the technology and business worlds are healthier, better, more innovative environment without software patents.

I do take some consolation that IBM seems to be "one of the good guys", in so much as our modern day IBM has not been as litigious as others, and hasn't, to my knowledge, used any of the patents for which I'm responsible in an offensive manner.

No longer hanging on my wall.  Tucked away in a box in the attic.

But there are certainly those that do.  Patent trolls.

Another former employer of mine, Gazzang was acquired earlier this month (June 3rd) by Cloudera -- a super sharp, up-and-coming big data open source company with very deep pockets and tremendous market potential.  Want to guess what happened 3 days later?  A super shady patent infringement lawsuit is filed, of course!

Protegrity Corp v. Gazzang, Inc.
Complaint for Patent InfringementCivil Action No. 3:14-cv-00825; no judge yet assigned. Filed on June 6, 2014 in the U.S. District Court for the District of Connecticut;Patents in case 7,305,707: “Method for intrusion detection in a database system” by Mattsson. Prosecuted by Neuner; George W. Cohen; Steven M. Edwards Angell Palmer & Dodge LLP. Includes 22 claims (2 indep.). Was application 11/510,185. Granted 12/4/2007.

Yuck.  And the reality is that happens every single day, and in places where the stakes are much, much higher.  See: Apple v. Google, for instance.

Musk concludes his post:

Technology leadership is not defined by patents, which history has repeatedly shown to be small protection indeed against a determined competitor, but rather by the ability of a company to attract and motivate the world’s most talented engineers. We believe that applying the open source philosophy to our patents will strengthen rather than diminish Tesla’s position in this regard.

What a brave, bold, ballsy, responsible assertion!

I've never been more excited to see someone back up their own rhetoric against software patents, with such a substantial, palpable, tangible assertion.  Kudos, Elon.

Moreover, I've also never been more interested in buying a Tesla.   Coincidence?

Maybe it'll run an open source operating system and apps, too.  Do that, and I'm sold.
