The Saturday Currents, OR: Why Care?

centaur 0
I prefer pictures of food to pictures of myself, but, since my phone stopped charging and started shocking people (along with emitting a lovely BURNING smell) you get old stock footage or Photo Booth for the time being. And now, the currents:
  • Currently Reading: Merida, Chasing Magic (because I want to understand children's books better, and I like the drawing of Merida's awesome red hair which is an inspiration for my drawings of Serendipity) and The Cognitive Neurosciences, Fifth Edition (because I am working on a project on the engineering applications of consciousness research, and research on the neural correlates of consciousness has exploded in the last twenty years).
  • Currently Rereading: The New Testament: A Historical Introduction to the Early Christian Writings (because Lent), Planning Algorithms by Lavalle and Reinforcement Learning by Sutton and Barto (because my robot navigation research is heating up and I want to understand the connections of reinforcement learning and classical planning, both of which have related but different ideas of value iteration; also because I'm planning on coding a small toy DQN to help me better understand the larger machinery I use at work).
  • Currently Dreading: Finishing my taxes, and finishing my edits on Shattered Sky by David Colby. Both so late! Sorry.
  • Currently Missing: My wife, on a business trip; my cats, at home waiting for me to finish up lunch, shift gears, and go home to go through The Tax Pile.
Why do these things matter? Why should you care? I know some people could care less about the incessant Facebook updates by people saying where they are and what they are doing. Some people I know even call sharing updates humblebragging as a way of shitshaming people into shutting up. (Hey guys! You know who you are. Message from me to you: Fuck off, kthanksbai.) Not me. I like seeing people say what they're up to; I like the birthday wishes on Facebook or the posts by famous writers saying, "ugh, I can has no brain today, here is a picture of a cat". I still remember after my Aunt Kitty died sharing on Facebook my last picture of her, and all the people I knew who showed up at the funeral only because I had posted it. It's human and natural to share with each other what we are doing. It lets each of us know that we aren't alone dealing with the good or bad. If status updates aren't the thing you're into, get off Facebook or Twitter. There's nothing wrong with that: I know many people have done it and have felt better for doing so. For me, there are so many people I only stay connected to because we have that instant means of connection. And (ssh: between you and me) there's always my ulterior motive: the more I write, the better I get at writing, and the more I discover and perfect my own voice. And just about everyone I know who does that just gets more interesting the longer that they do it. That's why I'm currently ... blogging. Hit save, then publish. -the Centaur

Dave, We’re On Your Side

centaur 0
The biggest "current" in my mind is the person I am currently worried about, my good friend and great Game AI developer Dave Mark. Dave is the founder of the GDC AI Summit ... but was struck by a car leaving the last sessions at GDC, and still is in the hospital, seriously injured. Dave is a really special person. I've been going to GDC longer than Dave, but it was he (along with my friend Neil Kirby) who drew me out of my shell and got me to participate in the Game AI community, which is a super important part of my life even though I don't do Game AI for my day job. Dave's friends and family have set up a Go Fund Me to help cover his medical expenses and the travel and other expenses of his family while he remains in the hospital in the Bay Area. I encourage you all to help out - especially if you've ever played a game and found the AI especially clever. Dave, you're in our prayers ... -the Centaur Pictured: Dave (on the right) and friends.

Just Checking in on the Currents

centaur 0
SO! Hey! GDC and Clockwork Alchemy are over and I'm not dead! (A joke which actually I don't find that funny given the circumstances, which I'll dig into in just a moment). Strangely enough, hitting two back-to-back conferences, both of which you participate super heavily in, can take something out of your blog. Who knew? But I need to get better at blogging, so I thought I'd try something new: a "check-in" in which I try to hit all the same points each time - what am I currently writing, editing, programming, etc? For example, I am currently:
  • Listening To: Tomb Raider soundtrack (the original).
  • Reading: Theoretical Neuroscience (book).
  • Writing: "Death is a Game for the Young", a novella in the Jeremiah Willstone multiverse.
  • Editing: SPECTRAL IRON, Dakota Frost #4.
  • Reviewing: SHATTERED SKY, Lunar Cycle #2 by David Colby.
  • Researching: Neural Approaches to Universal Subgoaling.
  • Programming: A toy DQN (Deep Q Network) to stretch my knowledge.
  • Drawing: Steampunk girls with goggles.
  • Planning: Camp Nanowrimo for April, ROOT USER, Cinnamon Frost #3.
  • Taking on: Giving up alcohol for Lent.
  • Dragging on: Doing my taxes.
  • Spring Cleaning: The side office.
  • Trying to Ignore: The huge pile of blogposts left over from GDC and CA.
  • Caring For: My cat Lenora, suffering from cancer.
  • Waiting For: My wife Sandi, returning from a business trip.
Whew, that's a lot, and I don't even think I got them all. Maybe I won't try to write all of the same "currents" every time, but it was a useful exercise in "find something to blog about without immediately turning it into a huge project." But the biggest "current" in my mind is the person I am currently worried about, my good friend and great Game AI developer Dave Mark. Dave is the founder of the GDC AI Summit ... but was struck by a car leaving the last sessions at GDC, and still is in the hospital, seriously injured. More in a moment. -the Centaur Pictured: Butterysmooooth sashimi at Izakaya Ginji in San Mateo from a few days ago, along with my "Currently Reading" book Theoretical Neuroscience open to the Linear Algebra appendix, when I was "Currently Researching" some technical details of the vector notation of quadratic forms by going through stacks and stacks of books, a question which would have been answered more easily if I had started by looking at the entry for quadratic forms in Wolfram's MathWorld, had I only known at the start of my search that that was the name for math terms like xWx.

The Cats You Save … and the Cats You Make Comfortable

centaur 1
SO RECENTLY I had a very vivid dream in which my veterinarian said to me "There are some cats you save … and some you make comfortable." I think the context behind that dream is worth a little unpacking, don't you? Loki the Loquacious is a cat that we saved. I came home one day to find him yowling and lethargic, sensitive to the touch yet unwilling to move, with a bloated feeling to the touch, and after a brief search online we rushed him to the nearby animal hospital who quickly diagnosed him with a urinary tract blockage, put him on a catheter, and nursed him back to health. Now, he hates the urinary tract pet food we feed him and the occasional water droppers when he’s not drinking, but unless this outdoor cat gets too adventurous, he’s probably got a long life ahead of him. Caesar the Conqueror is a cat that we made comfortable. He’d been made frail by a long battle with a thyroid condition when he decided to start peeing inappropriately indoors, so we had to make him an outdoors cat; but we were able to set up a relatively nice outdoor area for him. But then some nasal obstruction began interfering with his breathing, and he ultimately wheezed himself to death. We kept him comfortable, of course, until he took a rapid turn downhill, and then we had him peacefully put to sleep in my arms. As for Lenora the Cat … the jury is still out. She’s a healthy-looking, happy-looking, active cat, and even though she from time to time got pencil-eraser sized moles, and once even a larger lump on a back leg, they were always benign … until a month ago. Then a new mole appeared, and another, and another, until she had dozens of the tiny, not-itchy, not-bleeding, not-discolored bumps all over her body. We took her to the doctor, who found two more walnut-sized lumps in her abdomen; biopsies revealed these to be mast cell tumors (MCT or mastocytoma). Our doctor’s recommended regimen - a cortisone shot, followed by predisone and possibly other medications - tracks with what I’ve been able to research. Cortisone and similar drugs are recommended, and sometimes even can cure it, especially if it’s on the skin; but prognosis for lumps in the internals are more guarded - and she’s gotten another lump since the biopsy. So now we’re researching, weighing the options of continuing treatment vs seeing an oncologist now (our vet is of the opinion that we’d have to wait a few weeks for an oncologist to get good readings on bloodwork because of the cortisone shot, but if I was an oncologist I’d want to see that third lump right now). Cats with this condition can last three years with surgery, a year with palliative care … or can die within weeks if it’s serious. We don’t yet know if Lenora’s a cat we must make comfortable … or that we can save. Here’s hoping. -The Centaur

Dereliction of Duty

centaur 2
The following was written just before I left on Christmas vacation. The fact that I’m posting it three weeks later I think says something about the very point I was making in the article … so I’m going to let it stand as I wrote it the day that it happened. Here goes … — So, my cat died in my lap today, and while I didn’t kill it, I made it happen. I’d love to say I have a lot of feelings about that. The truth is, for me, departures leave a void. I don’t know what to feel, or don’t feel anything. Our precious little fraidy cat Caesar is gone, just gone, and the event passed without the reactions that movies and literature tell me happen when people go through life-changing events. And this is a change, make no mistake. Almost twelve years ago, I and my wife agreed to adopt two rescue cats, Nero (the big black butch one) and Caesar (the skinny Holstein-cow one afraid of crinkling paper). They’d been turned out onto the street by a couple who got on drugs, and were being fostered by one of our bridesmaids, who already had three tiny, frail, elderly cats, and was forced to keep both cats in a bathroom. We had Nero and Caesar shipped from the East Coast to the West, and made them a part of our lives. Nero’s long gone, victim of coyotes, but Caesar, with a different behavioral inheritance, survived and thrived, until a few years ago thyroid problems caused him to start to lose weight. He wasted away from twelve pounds to seven over the years, but we were mostly able to control it with medication, even when we ultimately had to put Caesar outside when, in his old age, he decided it was just fine to pee, like, wherever, because he’d reached the age where he didn’t have to give a damn anymore. Bay Area winters are, of course, as brutal as cream puffs, but we nonetheless set up a huge gazebo enclosure in the back yard, where a tarp, pillows, heating pads and collection of chairs, tables and cat condos gave him a comfy throne for over a year. But then he started wheezing. At first it was a cute little cooing-dove purr, and we thought he was just becoming more vocal. But it developed into a whistling, ticking sound as he labored for breath. Never comfortable on trips to the vet—always scared and panting, frequently pooping in the carrier even when in the best of health—on his last trip he was so freaked out they had to put him on oxygen. Tweaks to his medication and a cortisone shot helped for a while, but soon he was back where he started, with the recommendation of the vet that we make him comfortable. And we did—or, mostly, my wife did. She constantly reworked the outer area to make it a luxurious throne. A night owl herself, she fed him at all hours as, despite his decreasing weight of six and a half pounds, he became our most ravenous cat. And she stayed with him to brush him or sit with him or make him happy. And me? I’m the one who dragged us out to the Bay Area to work for a search engine company, and I’m the one who has to work long hours keeping the lights on now that I’ve transitioned from search to robotics. I’m the one who chose to take on a huge writing project at which I’m barely started, and I’m the one who chose to take on helping found a small press. I seemingly can’t say no to projects, not because I want to do so many projects, but because that’s the only way I have found to make the projects that I do work on into successes—constantly seeking other avenues, other points of connections that make the work that I do more valuable. So now I find myself with an enormous stack of responsibilities that I can’t easily unwind. For a variety of reasons, this has become even worse in the last six months, right when Caesar began his decline. Weekend after weekend I planned to spend time sitting in the back yard with the cats, and weekend after weekend I found myself working late at work or putting out fires at the small press. And week after week, I saw Caesar continue to decline. I even knew this was likely to happen, and took a picture intending to blog about caring for elderly cats. But life intervened, and Caesar has now passed without me ever posting that post about his decline. I can’t look at those pictures without thinking about dereliction of duty. Finally, I had enough, and started to arrange time to spend more time with Caesar. But it was too late. He’d grown too frail to clean himself, but no longer enjoyed brushing, pulling away from me when I tried to clean out his fur. He’d grown too scattershot to properly drink from poured water, but no longer enjoyed suckling my knuckle, making a few halfhearted attempts at the gesture that had calmed him so much as a young cat before wobbling away. I’d sit in the Adirondack chair in the back yard, hoping he’d come up and sit in my lap, and for a while he did, scrabbling his way up on me, getting a scratch, then shakily hop down and walk away. I eventually tried picking him up to put him in my lap, but he just wanted down. By the end, he barely tolerated a scratch behind the ears, and would quickly give up or walk away. As Christmas approached, I worried that he wouldn’t be here when I got back from visiting my folks—but last night, we noticed vomit on his pillow. Today he wasn’t sitting in his throne, and I found him lying against the fence in the back yard, muzzle covered in vomit, drooling on his paws, unable to muster the energy to eat and unwilling to tolerate my touch. I called in at work, woke up my wife, and we started calling for home pet euthanasia services. After half a dozen calls, we had an appointment arranged, and in the mid afternoon, a kindly veterinarian came by. Caesar had slid even further, with a soft, plaintive mew, and the vet gave him a sedative to help him sleep, and soon he was breathing easy for the first time in weeks. Five minutes later, I was sitting on the porch, with Caesar in my lap. The vet shaved a small patch of fur on his leg to get to his vein, and injected the final shot. I put my hand on his chest as he breathed his last, and the vet listened until his tiny heart stopped. The vet left us an impressed paw print in clay and a tiny bundle of fur, and took our cat, wrapped up in a basket, looking more comfortable than he had in six months. Then Caesar was gone. I wasn’t there when my dad died. I knew he was going, I even quit work so that I could be there for him while he was dying in Greenville, South Carolina, but for some reason at the time I felt like I had to periodically go back to my home town, Atlanta, Georgia, for what, I don’t remember now, to keep up the condo, or for my karate classes, or whatever, and on one of my returns to Greenville Dad passed while I was finding a parking space in the Greenville Memorial parking lot. Mom stood straight, but was in tears, and I knew what had happened; Dad’s body lay there, his eyes open, half lidded, his head turned partially aside, not rightable, the human body’s unconscious processes of self-stabilization and homeostasis finally ceased. So Dad was gone. I wasn’t there when my grandmother died. She’d been in the nursing home for a while, and the doctors warned us that she’d had a sharp slide. We came out to see her. Mom, strangely, didn’t want to go into the room, seeming somehow semi-estranged from her, despite being about as good to her as she could have been. I went see Grandma; she was holding her hands tight, her eyes half-lidded, barely registering my presence. We waited a long time, then returned the next day, and waited again. Finally we went for a late lunch, and when we returned, it was over. And Grandma was gone. I wasn’t there when my Aunt Kitty died. She’d been in decent health, despite a painful hip problem, and was jogging at the gym one day when she had a heart attack and fell off the treadmill. I was already on my way to Greenville for other reasons, but when I arrived, she again was barely holding on, each of her organs struggling to keep up, offloading their problems onto another. I parsed the jargon the doctors were saying and re-uttered the words to the family in words they understood, and they seemed comforted. She lay there, writhing a little; once her eyes, half-lidded, seemed to recognize me. But the family told me to leave, and after a few days, I flew back to the Bay Area. She passed the next day, and I flew back for the funeral. But Aunt Kitty was gone. I wasn’t there when Gray Cat died. He was a feral who stayed in the yard, and we slowly started the process of trying to tame him. I was the only one who could feed him. I was the only one who could pet him, and I did it with gloves. But we had started to play together, and he started to warm—then got in through the cat door and attacked my wife. She had to fight him off with a broom, and we ultimately decided that he was dangerous enough that we had to put him to sleep. But it was my wife who took him to the pound. And Gray Cat was gone. I wasn’t there when Caesar’s brother Nero died; as I said, he was taken by coyotes. He was an active outdoor cat, and we could even take him on walks without a leash. But that expanded his range, and he loved hunting on the watershed hill near our home. One night went out late at night, shortly before we heard the coyotes howl. He never came back. We posted flyers and walked the neighborhood, and checked shelters, but none of that mattered; we knew what happened the very next morning. And Nero was gone. Nero's death came without warning. I knew Caesar’s end was coming. I was determined to not let him die alone and afraid the way Nero did. So I kept close watch on him. I thought through the scenarios he might encounter and decided what I was and was not willing to put him through. The ultimate criteria, I decided, was if he could not breathe, if he could not eat, or if he could not get up; today, two of those three happened. So we acted. I was there when Caesar died. We let him lie where he had chosen until the drugs put him into a peaceful sleep, and then I held him in my lap until he passed. And after he was gone, I asked my wife to go for a walk, and I unloaded to her about how I wanted to have been there more. “No,” she said. “We are a team, and I was there for him, several times, every day, while you worked. While you spent your love on the cats that still wanted affection, I focused instead on Ceasar and gave him all the attention he needed. We gave him everything we could.” I still don’t know what I feel about this. I must feel something: I’ve been prompted to write two thousand words on it. But the feeling is that of a void. An uncertainty of how I should react or how I should feel. The only thing I know is that I made sure I was there when Caesar died. — Epilogue: Caesar is gone. Now one of our other cats, Lenora, has erupted in tiny bumps and larger lesions, along with two big lumps in her abdomen. Is it cancer, and she’s soon to be gone? Is it simply cowpox, and she’ll be fine in a month or two? I don’t know. But I do know I am making a special effort to be with her, and with my wife, and my friends and family, while they are alive. -the Centaur

Learning to Drive … by Learning Where You Can Drive

centaur 1
I often say "I teach robots to learn," but what does that mean, exactly? Well, now that one of the projects that I've worked on has been announced - and I mean, not just on arXiv, the public access scientific repository where all the hottest reinforcement learning papers are shared, but actually, accepted into the ICRA 2018 conference - I  can tell you all about it! When I'm not roaming the corridors hammering infrastructure bugs, I'm trying to teach robots to roam those corridors - a problem we call robot navigation. Our team's latest idea combines "traditional planning," where the robot tries to navigate based on an explicit model of its surroundings, with "reinforcement learning," where the robot learns from feedback on its performance. For those not in the know, "traditional" robotic planners use structures like graphs to plan routes, much in the same way that a GPS uses a roadmap. One of the more popular methods for long-range planning are probabilistic roadmaps, which build a long-range graph by picking random points and attempting to connect them by a simpler "local planner" that knows how to navigate shorter distances. It's a little like how you learn to drive in your neighborhood - starting from landmarks you know, you navigate to nearby points, gradually building up a map in your head of what connects to what. But for that to work, you have to know how to drive, and that's where the local planner comes in. Building a local planner is simple in theory - you can write one for a toy world in a few dozen lines of code - but difficult in practice, and making one that works on a real robot is quite the challenge. These software systems are called "navigation stacks" and can contain dozens of components - and in my experience they're hard to get working and even when you do, they're often brittle, requiring many engineer-months to transfer to new domains or even just to new buildings. People are much more flexible, learning from their mistakes, and the science of making robots learn from their mistakes is reinforcement learning, in which an agent learns a policy for choosing actions by simply trying them, favoring actions that lead to success and suppressing ones that lead to failure. Our team built a deep reinforcement learning approach to local planning, using a state-of-the art algorithm called DDPG (Deep Deterministic Policy Gradients) pioneered by DeepMind to learn a navigation system that could successfully travel several meters in office-like environments. But there's a further wrinkle: the so-called "reality gap". By necessity, the local planner used by a probablistic roadmap is simulated - attempting to connect points on a map. That simulated local planner isn't identical to the real-world navigation stack running on the robot, so sometimes the robot thinks it can go somewhere on a map which it can't navigate safely in the real world. This can have disastrous consequences - causing robots to tumble down stairs, or, worse, when people follow their GPSes too closely without looking where they're going, causing cars to tumble off the end of a bridge. Our approach, PRM-RL, directly combats the reality gap by combining probabilistic roadmaps with deep reinforcement learning. By necessity, reinforcement learning navigation systems are trained in simulation and tested in the real world. PRM-RL uses a deep reinforcement learning system as both the probabilistic roadmap's local planner and the robot's navigation system. Because links are added to the roadmap only if the reinforcement learning local controller can traverse them, the agent has a better chance of attempting to execute its plans in the real world. In simulation, our agent could traverse hundreds of meters using the PRM-RL approach, doing much better than a "straight-line" local planner which was our default alternative. While I didn't happen to have in my back pocket a hundred-meter-wide building instrumented with a mocap rig for our experiments, we were able to test a real robot on a smaller rig and showed that it worked well (no pictures, but you can see the map and the actual trajectories below; while the robot's behavior wasn't as good as we hoped, we debugged that to a networking issue that was adding a delay to commands sent to the robot, and not in our code itself; we'll fix this in a subsequent round). This work includes both our group working on office robot navigation - including Alexandra Faust, Oscar Ramirez, Marek Fiser, Kenneth Oslund, me, and James Davidson - and Alexandra's collaborator Lydia Tapia, with whom she worked on the aerial navigation also reported in the paper.  Until the ICRA version comes out, you can find the preliminary version on arXiv:

https://arxiv.org/abs/1710.03937 PRM-RL: Long-range Robotic Navigation Tasks by Combining Reinforcement Learning and Sampling-based Planning

We present PRM-RL, a hierarchical method for long-range navigation task completion that combines sampling-based path planning with reinforcement learning (RL) agents. The RL agents learn short-range, point-to-point navigation policies that capture robot dynamics and task constraints without knowledge of the large-scale topology, while the sampling-based planners provide an approximate map of the space of possible configurations of the robot from which collision-free trajectories feasible for the RL agents can be identified. The same RL agents are used to control the robot under the direction of the planning, enabling long-range navigation. We use the Probabilistic Roadmaps (PRMs) for the sampling-based planner. The RL agents are constructed using feature-based and deep neural net policies in continuous state and action spaces. We evaluate PRM-RL on two navigation tasks with non-trivial robot dynamics: end-to-end differential drive indoor navigation in office environments, and aerial cargo delivery in urban environments with load displacement constraints. These evaluations included both simulated environments and on-robot tests. Our results show improvement in navigation task completion over both RL agents on their own and traditional sampling-based planners. In the indoor navigation task, PRM-RL successfully completes up to 215 meters long trajectories under noisy sensor conditions, and the aerial cargo delivery completes flights over 1000 meters without violating the task constraints in an environment 63 million times larger than used in training.
  So, when I say "I teach robots to learn" ... that's what I do. -the Centaur

The Yearly Reboot

centaur 0
So one of the things I like to do each year, as part of my traditional visit to family over the holidays, is to drop in on a Panera Bread, pull out my notebook, review my plans for the previous year, and make plans for the new one. As of the 7th of January, I still haven't done this yet. Shit happened last year. Good shit, such as really getting serious about teaching robots to learn; bad shit, such as serious illnesses in the pets in our family; and ugly shit which I'm not going to talk about until the final contracts are signed and everyone agrees everything is hunky and dory. And much of this went down just before the holidays, and once the holidays started, I cared a lot more about spending time with family and friends than sitting by myself in a Panera. (In all fairness, the holidays were easier when I lived in Atlanta and came up to see family many times a year, as opposed to only occasionally). But I can recommend trying to do a yearly review. One year I decided to list what I wanted to do, both in the immediate future, in the coming year, in the coming 5 years, and in my life; and the next year, almost by chance, I sat down in the same Panera to review it. That served me well for more than a decade, and I find that even trying to do it helps me feel more focused and refreshed. And so that's precisely what I tried to do yesterday. I didn't accomplish it - I still haven't managed to "clear the thickets" of my TODO lists to get to the actual yearly plan, and I miss being able to take a whole afternoon at Panera doing this - but I did the next best thing, sitting myself down to a nice "reboot" dinner and treating myself to a showing of Star Wars: The Last Jedi. As someone said (a reference I read recently, but have been unable to find) the very act of doing something daily centers the mind. Here's to that. -Anthony

Everything was on fire until earlier today

Not literally; we were far south of the literal fires, which just barely missed the homes of our friends. But so many other things have been going wrong that it felt like things were on fire ... so no posts for a while, sorry. But tonight, I got to the last chapter of Dakota Frost #6, SPIRITUAL GOLD. I will likely finish this chapter Saturday. That makes today a good day. Time for some cake. -the Centaur Pictured: a cat break with Loki. Not how things look right now, but how I feel.

The Inevitability of Endings

centaur 0
All good things come to an end. I've known that since I was a child, when I asked my art teacher whether she had kept any of her childhood drawings, and she, with aplomb, replied no, they all burned in a house fire. But I've become more aware of that recently, as, one by one, places that I enjoy have come to an end. I've written about this before, but now it's struck the place where I've written much of this: Caffe Romanza is closing. As I've said before, it's all too easy to kill the golden goose: a business decision which appears to save money may actually undermine the way you make money. Perhaps Books Inc is struggling, but I and many others like me spend a lot late at night, and when they cut their closing hours from 11pm to 10pm it took away one of the reasons I had for going there. Moving from their glorious two-story corner location to a regular storefront will remove more reasons for more people; and eliminating the cafe will remove more reasons still, leaving it just another bookstore instead of a landmark destination. I don't have access to their books and I can't know all their reasons; maybe they were forced into this move. But I've talked to similar business owners about similar moves, and they never say, "we can't afford the late night staff" but instead say "we aren't making money on the late night traffic," which shows that they don't get the connection that the traffic they get at earlier hours is dependent on the later hours, and those of us that are night owls will be compelled to go everywhere. It's not the four buck cup of coffee we're paying for: it's the pleasant environment to drink it in the company of friends. Still, I wish Books Inc the best of luck in their new location, and I'll be sure to drop by. And I hope Jay at Caffe Romanza finds a new option. But I will miss that place where I wrote the bulk of my many novels ... but I will soon move on and find a new favorite, as the cycle continues. -the Centaur Pictured: Books Inc, an insanely large gift certificate for Caffe Romanza given to me by my colleagues on my tenth work anniversary, and Caffe Romanza, end of shift.

Facebook is not a Waste of Time

centaur 1
Facebook is not a waste of time: it saved my cat. Not long after my good friend Jim Davies shared a story about his beloved pug's sudden illness, I came home to find our beautiful cat "Loki the Loquacious" turned lethargic, not interested in food, and yowling at touches to his abdomen. This struck me as seriously unusual, and I was motivated by Jim's experience to look up Loki's symptoms. The recommendation: take him to the vet right away. So we did. It turned out we were right not to wait: this was a life-threatening urinary blockage which could have killed him through cardiac arrest. According to the emergency room vet, this is a particular issue for male cats near the end of winter, when for some reason they drink less. This leads to increasingly concentrated urine, crystallization of debris in the bladder, and, thanks to the (ahem) tapered nature of the male cat anatomy, can lead to blockages that can kill a cat in under 72 hours.
Fortunately we caught it in time, and they were able to catheterize him, put him on an IV and antibiotics. Loki started out as a feral near-bully cat, but after years of love the vets pronounced him a sweetie. They thought he would be home after a couple of days, though it was closer to five. But he's home safe now, and that happened because me and my friends were on Facebook, sharing our stories. Jim, if you're reading this, as I said on Facebook: I'm sorry for your loss. But thank you for sharing it. You helped me save my cat's life. -the Centaur

Expect major site updates in the months to come, as WordPress’s Themes and Pages now enable me to do things I could only formerly do with static pages and hand-coded pages, and it will all be backed up easier thanks to WordPress’s Jetpack plugin.

The things you learn helping other people with their web sites ….

Welp, it’s time: I’ve backed up the Library of Dresan three ways to Sunday, said a prayer … and now am planning to upgrade WordPress from 3.0.1-alpha-15359 to 4.7.3. I know that’s 1.7.2 full version numbers, but it’s been too long, and there are too many new features I need, so … time to press the button.

God, please help me! Everyone else, your prayers, please.

At long last, Jeremiah Willstone and the Clockwork Time Machine, my fourth published novel, is OUT in the world! You can get it wherever fine books are sold:

The Clockwork Time Machine tells the story of Jeremiah Willstone, a female adventurer from an alternate world called Victoriana, where, because women’s liberation happened a century early and twice as many brains ended up working on hard problems, science has advanced more in 1908 than it has in our world today - but inadvertently, these scientific advances attracted the attention of aliens called Foreigners, who have come calling to make this world their own!

When Jeremiah’s treacherous uncle steals a dangerous alien weapon and secrets it away on an airship to a possibly hostile shore, Jeremiah leads a strike team to retrieve it - and finds herself chasing him across the seas of time itself, with her uncle just possibly aiming to upend the entire world order she holds dear! With time running out, Jeremiah must sacrifice everything she is to save everyone she loves.

No, I’m Not Dead

20170223_114426.jpg It might not be immediately apparent from this shot, but outside, it’s sunny and the weather is nice. That’s despite the mammoth evacuation of San Jose yesterday … which, for the record, was nowhere near me: Screenshot 2017-02-23 14.25.11.png I live near Coyote Valley, not Coyote Creek - two totally different areas miles apart - so my home was providentially spared. I was, however, woken up yesterday morning by a text, a call, and a Messenger message, all wondering whether I was OK. My wife, off to the East Coast on a business trip, called to ask if I’d evacuated yet; I looked out the window to sunny skies, sleeping cats and the early-morning sound of a leaf blower, and said no. Sorry for concerning you, I know there have been three different disasters / evacuations in San Jose recently! Last night at dinner at Alexander’s, the server, my good friend Todd, reported three different closures of Highway 17 that kept him from work - one that involved a gun battle and five hours trapped in his car, but the rest, weather. 101 in San Jose has suffered similarly. I think these are somehow all related to “atmospheric rivers” which fortunately have dumped all their water before hitting my area. I’d never heard of these before, but apparently the terminology has been around since the 90s. Thanks for your concern, though! I too am pleased I am not dead! I’ll try to keep it that way! -the Centaur

Cover Reveal: JEREMIAH WILLSTONE AND THE CLOCKWORK TIME MACHINE!

centaur 0

For those wondering what I’ve been up to for the last six months, the biggest thing is THIS …

Jeremiah Willstone and TCTM.jpg

At long last, JEREMIAH WILLSTONE AND THE CLOCKWORK TIME MACHINE is coming to print! We’ll be picking the actual release date in the next few days, but I can’t think of a better gift for my birthday than seeing the cover of my new novel!

Here’s a sneak peek at the back cover blurb:

From an Epic Award winning author comes a sprawling tale of brass buttons, ray guns, and two-fisted adventure!

In an alternate empire filled with mechanical men, women scientists and fantastic contraptions powered by steam, a high ranking officer in the Victoriana Defense League betrays his country when he steals an airship and awakens an alien weapon that will soon hatch into a walking factory of death.

Commander Jeremiah Willstone and her team must race through time in a desperate bid to stop the traitor's plan to use the alien weapon to overthrow the world's social order. With time running out, Jeremiah may have to sacrifice everything she is to save everyone she loves.

"Addictive, sassy, sexy, funny, intense, brilliant." -Bitten By Books, on Frost Moon

Epic Award winner Anthony Francis writes the Dakota Frost, Skindancer series and Jeremiah Willstone series while working on robots for "the Search Engine Which Starts with a 'G'."

Prevail, Victoriana!

Welcome to the Future

Welcome to the future, ladies and gentlemen. Here in the future, the obscure television shows of my childhood rate an entire section in the local bookstore, which combines books, games, music, movies, and even vinyl records with a coffeehouse and restaurant.

20161227_171758.jpg

Here in the future, the heretofore unknown secrets of my discipline, artificial intelligence, are now conveniently compiled in compelling textbooks that you can peruse at your leisure over a cup of coffee.

20161230_195132.jpg

Here in the future, genre television shows play on the monitors of my favorite bar / restaurant, and the servers and I have meaningful conversations about the impact of robotics on the future of labor.

And here in the future, Monty Python has taken over the world.

Perhaps that explains 2016.

Learning while Contributing

20160903_215541.jpg

I’ve been going to conventions for about thirty-five years, but have appeared on panels only in the last ten, and even that only consistently for the last five - so I still feel like a fanboy up with all the more experienced authors. And while sometimes I have a lot to contribute, I often find it’s better not to ask whether I have something to say, but whether I have something to add. It’s frankly awesome to be up here with luminaries like John Ringo or Esther Friesner, and it’s often just best to to sit back and listen - but even then, don’t give up on yourself. I was on three panels today with more experienced people, and I made sure I both shut up and listened and stepped up and said something at the appropriate time - with the result being that several people came up to me and thanked me for my contribution to the panels that I’d been on. Several of the authors got together afterward, and we all seemed to think that it was our interactions with each other that made the panels great. So … think of what you can add, but never give up on your own unique contribution. It’s there, you just have to find it.

Con Crud!

centaur 0
So, I had all sorts of plans to post on my upcoming panels and the ambience of Dragon Con, but I overslept. Not by, like, an hour, or two hours, but more like eight hours. Sure, I got up and killed my alarms, a few times, but what really happened as I kept trying to get up and kept crashing out was that I realized I had caught a case of con crud. Science fiction conventions gather an enormous amount of people, and hence, their diseases, and hence: con crud, that mysterious illness that hits you a day or two after you get to a con. I know a lot of people who have been knocked out by it, but it's hit me hard only two or three times. This time, I ended up sleeping on and off for twelve hours out of sixteen. Fortunately I didn't get the cough or sniffles, though I felt them starting. But I rested up, and got up when I felt rested, and even though I missed hitting the dealer's room today, I had a lot of fun at my two panels. So what I'm saying is, be good to yourself. It's easy, when you're at a con on a mission, to get caught up on all the things you could do. Well, do the things you should do, take care of yourself, and relax: cons will roll around again, and you want to be healthy enough to survive them.
