Tales of the Sausage Factory

A Reflection on the First Thanksgiving.

It is fashionable now to conflate the 250 year American experience between the European settlers and the Native Americans as simply one of oppression and displacement. Or, as one friend put it: “I’m Thankful that a bunch of European religious fanatics came over and displaced the native population.”

But it wasn’t like that at the First Thanksgiving, or for about 35 years thereafter. In failing to appreciate the efforts of English settlers and Wampanoag tribes in the region to live together in peace in the first three decades of English migration to Plymouth, we ignore both that a better world was possible — and that we have the capacity to build a better world today . . .

Tales of the Sausage Factory

In Memoriam: Wally Bowen — Internet Pioneer, Community Activist, and A Hell of God Guy.

Last week, we lost a true leader for rural communities, a true champion of social justice in communications policy, and a personal friend and inspiration.  Wally Bowen, founder of Mountain Area Information Network, died of ALS (aka “Lou Gehrig’s Disease”) on November 17 at the age of 63.

You can read his official obituary here. As always, such things give you the what and the where, but no real sense of what made Wally such an amazing person. I don’t have a lot of personal heroes, but Wally was one. Simply put, he gave the work I do meaning.

It’s almost Thanksgiving, and I am truly thankful for the time we had with Wally on Earth, even if I am sorry that it ended too soon. I elaborate below . . .

Inventing the Future

Big milestone in our VR today: bow and arrow are cool, and the reasons why are cooler

coming at youWe had our weekly company meeting in HighFidelity today, just like we always do. For a while now, we’ve all been using Oculus VR headsets and trackers for our hands, and we now have avatars that look like like us. We have good multi-user physics and whole-body tracking-animation for our avatars.

Today one of the guys showed off his recurve bow. As long as you hold it, it re-arms with arrows. Pull the string back with your physical hands, aim and let go, and the arrow flies. It’s basic fun with weaponry. People took turns playing with it.

But quickly people started saying, “Oh, shoot me between the eyes!” (including our CEO). It’s pretty cool to see the arrow coming right for you. Can’t do that IRL! (In Real Life.)

But I never said this. Instead, I stood among the circle of avatars in front of the shooter, and kind of stared him down. Without thinking, I conveyed, “Come at me, bro”, but with nothing so obvious as arms wide or a Neo-like “come on” finger-wave. My avatar could do that with just a stretch of my physical arm or squeeze of my hand, but I didn’t gesture or say a word. Our team is pretty competitive, but we’re not the kind of folks who would shoot the person in front of us without being invited. We need to be invited. But multiple shooters did shoot me. Non-verbal communication works!

General Exception

The End of Email Alerts

So, those of you who have signed up for email updates from the site may have seen a large vomit of spam from our site yesterday. Sorry about that. I loaded some posts in from a backup, and the WordPress plugin decided that meant it should send out alerts for those old posts again. Because, obviously.

In combating this latest accidental spam, I also noticed that the plugin in question has an unpatched security hole in it and has been withdrawn. So, I need to delete it ASAP. Instead of trying to find an alternative, I’m going to retire the email updates again, and this time permanently. When I mess up the site usually, the worst that happens is that it appears messed up in your browser. If I mess up something that involves email alerts, I can end up sending out thousands of junk emails. I’m tired of that.

My Thoughts Exactly

Synthetic biology legend George Church & I talk about science and civilization

In March of 2015, George Church (whose accomplishments in biology (and visions of the future) are too numerous and significant to for me to recap here, so just go read about ’em here or here or here) & I sat down to talk for about an hour an a half on topics ranging from the Stuxnet cyberwarfare weapon to civilization (and its foes) to surgery on Mars. I edited the discussion into four segments of 17 or 18 minutes each, conveniently gathered here for your edification, amusement, and enlightenment. As a special bonus, at the end of this blog I’ve included the new Foreword to my novels that George was generous enough to write, just in time for the SynbioBeta Conference taking place in San Francisco this week, where I’l be hawking my wares, as is my wont.

LTE-U v. Wi-Fi: The Abreviated Version

I recognize that Part I and Part II of my LTE-U/Spectrum Game of Thrones ran somewhat long and dense, even by Tales of the Sausage Factory standards. So for those of you looking for something a bit lighter, I’ve prepared an abbreviated version — this time based on a different epic saga involving the supernatural, mysterious circumstances, and . . . Scoobie snacks?

Ruh roh! Time to solve another groovy mystery below . . .

Tales of the Sausage Factory

My Insanely Long Field Guide To the LTEU Dust-Up Part II: A Storm of Spectrum Swords.


The Vorlons have a saying: “Understanding is a 3-edged sword.” In this case, the three edges are the Wi-Fi dependent, the LTE dependent, and the Federal Communications Commission (FCC).


Last time on Spectrum Game of Thrones (hereinafter “SGoT”) I spent 6500 words discussing the first two edges of the sword. The Wi-Fi dependent side has strong reason to suspect the LTE-U crowd of either reckless indifference or actual malice toward deployment of Wi-Fi based streaming services in the newly refurbished U-NII-1 band up in 5 GHz. Even if the Wi-Fi Dependents could trust the motives of the LTE-U crowd, what happens if everyone is wrong about the ability of the two technologies to co-exist? Under the current structure, the Wi-Fi dependents would be screwed, and they could do nothing about it. So the rational Wi-Fi Dependent must fight tooth and nail against deployment of LTE-U.


It doesn’t help that the Wi-Fi Dependents know that this is an utterly impractical solution for the long term. Unless there is a way to answer the two questions central to the survival of Wi-Fi streaming in U-NII-1 in the face of LTE-U (what happens if something goes wrong, what happens if somebody deliberately does something bad post-deployment), rational Wi-Fi dependents have no choice but to fight deployment.


The LTE-U crowd, for its part, has good reason to want to deploy LTE-U and has a legitimate gripe that Wi-Fi Dependents cannot keep saying no without defining the conditions for yes. If we admit the possibility that we can deploy LTE-U consistent with reasonable use of Wi-Fi (which everyone does), then there has to be some way to actually deploy it. And while I savor the fine irony of seeing licensees in the same position I have been in countless times, it is still crappy policy. Also, unlike me and other would-be new entrants, the wireless guys and Qualcomm have enough political muscle to make the current stalemate untenable. Eventually, they will get to deploy something.


Which brings us to the third edge of the Vorlon sword of understanding – the FCC. As I shall explain below, government actually is the solution here. Not by imposing a standard or a rule, but by providing both sides with a process for resolving the problem. As a happy side effect, this will also help resolve the general class of problems that keeps coming up on how to manage more and more intense use of the airwaves. Just like we all learned in high school math, and most of us forgot about 30 seconds after the exam, you solve an intractable problem by trying to break it up and simplify it into solvable problems.


The only problem is, and I know most people are not going to believe me, the FCC actually hates asserting and clarifying its authority. Yes. Really. Which gives rise to the question of whether the FCC actually has the willingness to do what needs to be done and create a general solution, or if they will continue to try to do the minimum possible, what I call the “Snow Goons Are Bad News” approach immortalized in this classic Calvin and Hobbes strip.


So, as we get to SGoT 2: Storm of Spectrum Swords, we come to another dramatic turning point. Will the Wi-Fi Dependents and the LTE-U Dependents see the wisdom of allowing the FCC assert authority over the land of Spectrumos? Can the FCC be persuaded to fulfill its destiny and its duty? And will the anti-Regulatory Zombies from beyond the Wall crash the party and devour both Wi-Fi and LTE-U because of their hatred of the FCC?

Inventing the Future

Avatar Results

Some terrific initial results of our Avatar IK. This is not from post-processing of someone wearing a motion-capture suit with a bunch of ping-pong balls stuck to it.  All the movement is instead driven by a (developer’s edition of a soon-to-be-retailed) gaming VR headset (capturing head position and orientation in 3D), and two (somewhat dodgy) gaming hand-controllers (capturing each hand’s position and orientation, plus a trigger). As described here, we interpret these 3 measurements to trigger an appropriate underlying base animation, which then provides more measurements to drive a realtime inverse-kinematics skeleton.

My Insanely Long Field Guide To The LTE-U Dust Up. Part I: Spectrum Game of Thrones.

I keep reading about the LTE-U/LAA dust up and deciding that, as I predicted back in January, this has become the epic Spectrum Game of Thrones. Which means it’s time for an epically long series of Insanely Long Blog Posts.


For those just tuning in, I can sum up this issue as follows: should we worry that wireless carriers are looking to deploy a protocol developed for the 4G licensed world (LTE, or Long-Term Evolution) over unlicensed spectrum (called “LTE-U” for LTE over unlicensed or “Licensed Assisted Access,” for reasons I explain later) will “kill” Wi-Fi — for various values of the word “kill.” You can read some stuff on this from my Public Knowledge colleagues here and here.


Let me give you the headline version:


  • Can you build a version of LTE-U that plays nicely with Wi-Fi? Yes!
  • Can you build a version of LTE-U that looks like it should play nicely but when you deploy it over hundreds of millions of devices it would stomp all over Wi-Fi and crush it flat totally by accident? Absolutely!
  • Can you make and deploy a version of LTE-U where it plays nicely unless the mobile carrier decides it doesn’t like competition from Wi-Fi first providers of rival mobile video and voice services? You bet your sweet patootie!


A lot of the argument you see in the press and from the LTE-U supporters has to do with whether the LTE-U Forum (more on them later) have the best interests of wireless users at heart, have gone to great lengths to make sure LTE-U will play nice with Wi-Fi, have released their specs on the LTE-U Forum website, etc. etc. But none of this addresses the points above. What happens if you put this out there and stuff goes bad, either by accident or intentionally.


To understand the thinking here, imagine Qualcomm and the rest of the LTE-U Forum are Iran building a nuclear reactor for peaceful purposes. Google and the Cable industry (and us public interest types, for all that anyone notices) are Israel and the Sunni Arab states like Saudi Arabia and Egypt. Iran/LTE-U forum maintains they are building their nuclear programs for peaceful purposes. GOOG/Cable asks how they can be certain, given that the same technology might (a) screw things up accidentally; and, (b) give the carriers the capability to screw things up intentionally, if they ever start to feel the competitive heat. Qualcomm, LTE-U Forum, et al. are shocked, hurt and offended that anyone could even suspect such a thing, despite everything Qualcomm has done in the last 3 years to turn LTE-U into a “Wi-Fi killer”, and despite some of the biggest global carriers telling 3GPP to shut out non-carriers from first generation of LTE over unlicensed. According to Qualcomm, the only reason anyone would question the peaceful intentions of LTE-U Forum is for anticompetitive reasons.


But here’s the complicated thing. As I’ll explain below, it’s not like LTE on unlicensed is intrinsically bad. There are lots of really good pro-competitive reasons for carriers to start using LTE on unlicensed. Heck, it may ultimately turn out that a stand alone version of LTE on unlicensed is as useful (or even more useful) than Wi-Fi is today. Who knows? That’s the beauty of the unlicensed band — innovation without permission and all that good stuff.


This puts the Federal Communications Commission (FCC) in a rather awkward position. On the one hand, the FCC recognizes the real problem of LTE-U, accidentally or intentionally, messing up Wi-Fi. Additionally, while Wi-Fi is in the unlicensed band and must therefore accept whatever interference comes its way, is only ONE of many, many protocols, etc., you don’t let companies with the obvious incentive to screw up Wi-Fi develop and deploy a potential Wi-Fi killer with no safeguards. But since the success of the unlicensed space comes from its flexibility and easy deployment, how do you not ultimately approve some version of LTE-U/LAA? Are we going to lock in Wi-Fi as the protocol for unlicensed the way LTE is the protocol for mobile wireless? That could be just as awful for the future of innovation as letting LTE-U/LAA trash the place.


To make sure all you Tales of the Sausage Factory Readers know what’s going on, I bring you yet another in my occasional “Insanely Long Field Guide” series. Below, I cover everything from a brief refresher on what the heck is “unlicensed spectrum” v. “licensed spectrum,” the history of what’s going on here, and why I focus on Qualcomm rather than the wireless carriers as the chief bad guys here. However, as this is too long even for me, I will need to break this up into two insanely long pieces. In Part 2, I’ll explain about the FCC, why it got involved, why this is so complicated from the FCC’s perspective, and what the FCC can do about it.


But first, our insanely long background briefer below . . . .

Inventing the Future

High Fidelity Avatars: Interpretive Motion IK

meryWe’ve come up with something that I think is quite cool for conveying presence though our avatars. Interpretive Motion IK is a technique in which all kinds of inputs drive a small set of animated motions, and then the animation results and additional inputs both drive an Inverse Kinematic system. This gives us a rich set of built-in avatar behaviors, while also making use of an ever-evolving set of input devices to produce a dynamic and life-like result.

Why Aren’t Avatars More Like Us?

From static “head shots” in a text chat, to illustrations in a book and famous faces in a movie, avatars give us an intuitive sense of who is present and who is doing what. The story of an animated movie (or high end game “cut scene”) is largely shown through the fluid motion of anthropoids. A movie studio can hire an army of artists, or record body actors in motion capture suits. But a virtual world does not follow a set script in which all activity can be identified and animated before use. Avatar animation must instead be generated in real time, in response to a world of possible activities.

This challenge leads some systems to just show users as simplified images, or as just a head, a disembodied “mask and gloves”, or a mostly un-animated “tin can” robot. This may be appropriate for specialized situations, but in the general case of unlimited high fidelity virtual worlds,  the lack of whole-body humanoid animation fails to provide a fulfilling sense of personal immersion.

When it works well, the interpretation of motion is so strong that when another avatar turns to face your avatar, we describe it as “YOU can see ME”. In fact, the pixels on the screen have not turned, and cannot see. Think of the personality conveyed by the Pixar desk lamp hopping across the scene and looking at the camera, or the dancing skeletons of Disney’s early Silly Symphony. Unlike Disney and Pixar, High Fidelity aims to capture this rich whole-body movement as a realtime result of dynamic user input. Alas, today’s input devices give us only incomplete data. Interpretive Motion IK allows us to integrate these clumsy signals into a realistic sense of human personality and action.
