The Doubly-Linked List Appears to Have Been Patented

I saw a tweet today that said “The doubly-linked list, a structure I studied thirty years ago, has recently been patented.” After giggling at the absurdity of the idea, I went and at a patent dated 4/11/06 that appears to be for the doubly-linked list. The prior art was extremely thin, only went back to 1995, and didn’t mention that entire computer languages have been created around the list as a core data structure. One of my first Pascal programming exercises in high school (in 1981 – on an Apple II using USDC Pascal) was to write a series of operations on lists, including both linked and doubly-linked lists (I always thought it was funny they were called “doubly-linked” instead of “double-linked” lists.) Anyone who ever graduated from MIT and took 6.001 learned to love all varieties of the linked list, including the doubly-linked one. That was 1984 for me by the way.

Sawyer Opines on the Eastern District of Texas

My friend Sawyer is back with another post in his series of talking about software patent issues. As I mentioned before, Sawyer is a real person named after our intrepid friend in LOST (I haven’t seen it this week – no spoilers please) who has agreed to help us navigate the parallel universe known as software patent land. I’m channeling Sawyer’s points of view as a public service announcement since he’s uncomfortable being named publicly – these are his words, not mine. Today’s post is on the famed “Eastern District of Texas” (EDTX), one of the most popular places in the United States for patent litigation.

Software Beats Network In My Book

Remember rock / paper / scissors? It’s a beautiful kids game that unlike tic-tac-toe regularly results in a winner. Paper always beats rock. Rock always beats scissors. Scissors always beats paper. But what happens when you only have two – say “software” and “network”. Whenever I’m at a Silicon Flatirons event, I always get into an argument with someone from the telecom world about “what the Internet is.” Most of the time I try to listen patiently for about 30 seconds as the telecom person explains to me how without them there would be no Internet and the applications that exist are merely “traffic” on “their network.” They then try to tell me crazy things like “no one will ever need more than 100 Mbps” and say snarky things like “who knows, maybe Google will spend more on their 1 Gbps buildout then they did on the 700 MHz spectrum.” I try to remind them that when I was 13 someone told me “you’ll never need more than 48k of RAM” and then again when I was 18 someone told me “you’ll never need a hard drive bigger than 10MB".” Oh, the things people say in the throws of competitive pressure. Innovation? Who needs innovation. Let’s take a big helping of regulation instead.

The Proliferation of Standardized Seed Financing Documents

As of today’s announcement that Ted Wang at Fenwick & West has collaborated with a group of bay area early stage VC’s and angel investors to create the Series Seed Documents we now have – at my count – four different standardized seed financing documents floating around the industry. TechStars Model Seed Funding Documents (by Cooley) Y Combinator Series AA Equity Financing Documents (by WSGR) Founders Institute Plain Preferred Term Sheet (by WSGR) Series Seed Financing Documents (by Fenwick & West) Many smart and capable people have either worked on these various docs on signed on as supporters. However, until there is one standardized set of documents that everyone – especially the various law firms agree on – I don’t expect there to really be a standardized set of seed financing documents. I wrote about this in my post The Challenge of The Ideal First Round Term Sheet.

New Orleans Rock ‘n’ Roll Mardi Gras Marathon

Marathon #15 is in the bag – I finished the New Orleans Rock ‘n’ Roll Mardi Gras Marathon in a time of 05:15:05 yesterday. Here’s a video of me crossing the finishing line. It was a beautiful day for a marathon – the temperature was 50 degrees and the sky was clear. There were about 18,000 runners (most for the half marathon) and like most Rock ‘n’ Roll races it was extremely well organized.

Do You Know The Difference Between A Browser and a Search Engine?

Videos like this one remind me that I live in a very tiny corner of the universe. Only 8% of the people interviewed (out of a sample of over 50) correctly defined a browser. It also shows how effective Google has been in their approach to branding, especially given that they just aired their first TV commercial a few weeks ago.

Great Pogoplug Review in the WSJ

I love the Pogoplug. We’ve been investors in the company for about a year and it has been a blast working with the team. Pogoplug is in our Digital Life theme and has a lot of conceptual similarities to our previous investment in Sling Media (now part of EchoStar). We love products like the Pogoplug and the Slingbox “software that ships with a little plastic box that does magic stuff” that, in Pogoplug’s case, provides you access to any of your external hard drives from anywhere in the world on any device.
