Terminals are weird: quirks of the ways control and alt keys are represented in a standard unix style terminal.

I bought a used Thinkpad to replace my long-lived but now-dead netbook, and while it’s a much better machine in relative terms, it’s still kind of a weenie compared to the Mac on my desk. It’ll be a fine coding/email/browsing device, but I have this fantasy of remoting in to the Mac, using the Thinkpad as a dumb terminal, so I can also drive Xcode from afar. I’ve set my desk up to be as comfortable a coding station as I can manage, but there are many other places I’d like to be as well…

My question for the interwebs: is it possible to set up a VNC server on a Mac such that there is no way to log in with a password, that authentication is only possible through some pre-set key pair? I know that one can do this sort of thing with Git but I am hazy on the details. I imagine that I would generate a file, copy it onto the laptop via USB stick, set some configuration somewhere, open the relevant port on my home router, and then control my desktop machine without worrying that it is protected by something so flimsy as a password.

Now that its metacarpal bone contains a couple of screws, my thumb appears to have developed the ability to detect changes in barometric pressure. Cool! I am a human weather station!

Okay, to be honest it’s annoying and it kind of hurts, but if it’s the worst I have to deal with as a long-term consequence of last year’s motorcycle crash then I think I am OK with that.

It’s funny to watch my creative outlets shift back and forth over time, since the activities themselves are about as conscious and intentional as they could be, and yet the overall course of the river seems to meander through loops I can only see in retrospect.

I did a ton of sewing last spring, but I haven’t touched a machine in months. The middle of the summer was all about organizing Floodland, which went off really well, but exhausted me. Since then I’ve been cruising through a more than usually quiet and solitary mode, spending most of my free time deep in the guts of some really enjoyable compiler hacking.

Now the weather is turning, I seem to have a resurging interest in connecting with my friends, and I’m thinking about starting up weekly Rock Star Thursday Dinners. Perhaps this also has something to do with the changing of the seasons and the approaching dark months, but I’m feeling a spark of interest in some lighting projects that have been neglected during this bright summer.

Delightful. By Mark Morford:
Burning Man is so very wrong

Here’s what you need to know about Burning Man in this fine year of our unchecked chaos, 2014: Nothing.

I mean, just forget everything, all right? Whatever you’re heard, read, seen, rumored, teased, whispered, Facebooked, Instagrammed, linked to, thought about or had muttered in your general direction in an Uber fever dream anytime in the past month. Year. Decade.

Because it’s almost certainly wrong. Delightfully, hatefully, stupidly, shamelessly, deliberately, resentfully, innocently or even inadvertently, it doesn’t matter – there’s almost nothing the slightest bit accurate in what the modern media has said recently about the famed art/camping/dance/survival festival – now in its 28th year – happening right now out in the Nevada desert.

Ready for Rain:
Why Seattleites Crave the End of Summer

It’s not simply the arrival of rain, but the transition to a different environment and way of life. The drear has a certain dark beauty; a low-contrast softness. There’s no need to squint or close the blinds. Even the sound of the rain on our house is music to my ears, a lullaby.

First half of roof over back porch

Well that wasn’t hard! Took just a little over an hour to nail four of the five panels up. Just a simple project really, since the frame was already there, but it’ll be nice to keep the porch dry and available for outdoor meals during the rainy months.

Charles Stross’ essay about his support for Scottish independence illustrates a view of geopolitics which seems entirely sensible, and which accords with my feelings about Cascadian independence.

My feeling is that we’d be better served by a group of much smaller nations working in a loose confederation or treaty structure. Their job should be to handle local issues (yes, this is localism) while compartmentalizing failure modes: the failure modes of a gigantic imperial power are almost always far worse than those of a smaller nation (compare the disintegration of the Soviet Union with that of Czecheslovakia). Rather than large monolithic states run by people at the top who are so remote from their constituents that they set policy to please lobbyists rather than their electors, I’d prefer to see treaty organizations like NATO and the EU emerging at consensus after discussions among numerous smaller stakeholder entities, where representatives are actually accountable to their electors. (Call me a utopian, if you will.)

We did it and it was awesome

Here is a note I sent to the Floodland mailing list, thanking everyone who helped make it happen. No sense rewriting it when it sums my feelings up pretty clearly:

I have yet to start unpacking my car, but I’ve had a shower, a good night’s sleep in my own bed, and just now I’ve had a chance to upload some pictures:

I don’t know how to describe the experience I had this weekend without gushing. Not only did you all pick up the Floodland vision and run with it, but you took it off in a bunch of other directions I’d never expected, and you did it all with a smooth, comfortable competence that left me feeling like I shouldn’t have spent quite so much energy worrying about the details.

But I wasn’t just watching the kind of well-oiled machine that a close-knit crew can become: while many of us have worked on each other’s projects before, one of the big reasons for creating a new event is to welcome new people in, giving them a platform to explore their own ideas and develop their own skills along with us old-timers. I was happy to see good friends at Floodland but I was also glad that I got to make some new friends too.

We had beautiful weather, and even the little bursts of rain were welcome; we had the most consistently gorgeous sunsets I can ever remember seeing; we had lovely spaces to relax and to dance, we had art and costumes and performances and fire. It was all there. Everywhere you could see the potential hanging in the air, and everyone I talked to expressed enthusiasm about coming back and doing it again next year.

If all we accomplished was a proof-of-concept camping trip, that’d have still been success: but we went far beyond that and actually threw ourselves a full-on burn event. Thank you for all the energy you put into this, the good attitudes and adaptable creativity you brought to the various obstacles we encountered. Thank you for trusting me when I came to you with this crazy plan in the first place, and thank you for the honest, thoughtful, enthusiastic feedback so many of you shared as we all started to imagine what next year’s festival can be.

I have a new phone. It is Divide’s old Nexus S. (Thanks!) Alas, since I’m a paranoid freak who doesn’t believe in giving all my data to Google, I lost all my numbers. Entire address book: gone.

Have we ever communicated by phone? Does your phone contain my contact information? Text me, please! Send me your name. Thanks.

Floodland 2014 happens next weekend.

I’ve been trying to keep it small and focused, and these sorts of events have a way of getting out of control if you announce them too broadly. But we’re nearly down to the wire, this has been one of my major free-time activities for the last couple of months, and I’m really excited, so it’s time to spill.

We have art, music, shade, performance, cushy lounging, and awesome people. We’re going to go spend a long weekend in the sagebrush and make a beautiful temporary village there.

There will be a big “center camp” area for low-key lounging, workshops, craft projects, and socializing. We’ll have a big custom propane bonfire set up nearby – not that it gets very cold at night out in Eastern Washington during the summer, but a fire is still an important social center. And we’ll have some art projects, LED sculptures and the like.

A bit further away, we’ll have another big shade, covering a sound system and a DJ booth, with fabric and lights and some really impressive LED matrix displays…

It’s going to be a really fun weekend. With a little luck and a lot of hard work, this will become a new yearly event, akin to a “regional burn“. But this year will be special; it’s full of wide open possibility, and nobody really knows what to expect.

I haven’t said much about work in a while. I’ve been part of a startup for the last year and a half, and our web site just went live. Development proceeds steadily… it’s all coming together and looking pretty good.

The fellow living next door to Rock Star Parking is 92 years old; he’s been living in the same house for 65 years. His grandson was out cleaning up the back yard this morning, and I said hello. We chatted a bit, and he informed me that the name I gave my house is more apt than I had any way to know: Jimi Hendrix’s first band apparently used to practice in his grandfather’s basement, immediately across the driveway from my bedroom window.

UrbanGems is a little hot-or-not style site that asks you to pick, from two photos, which shows the prettier scene. This data yielded an algorithm for automatically measuring the beauty of street scenes in photos from Flickr, which is now being used to develop a mapping algorithm which will find not the shortest but the most scenic route from one place to another.

Goodness 2014

That was the happiest, most satisfying festival experience I’ve ever had. A lodge in the woods, a couple of big grassy meadows, tall trees, a river, and a hundred or so friends, plus forty or fifty of their kids, throwing down years of Burning Man equipment and experience for a few great days of music and conversation and craft projects. I danced til dawn both Friday and Saturday night. We wore all of our most awesome and ridiculous outfits. We strung brightly colored lights everywhere. We had a big potluck and not one but two campfires going all night.

Sleeping in the back of the Rover is still a great solution for festival camping; I just fold the seats back, flip down the tailgate, and roll out a bunch of blankets. Super simple and comfortable. I think I will cut & sew the canvas tarp I’ve been using as a shade into something that fits over the car a little better, though.

New propane fire pit


This propane burner holds a pile of rocks, diffusing what would normally be a simple blue flame into a big wispy orange flame like a traditional campfire. I have a perfectly serviceable firepit at home, but this portable burner will be great for festivals and camping in areas with burn bans, where it would be important not to leave a bunch of ash or create flying sparks.

Motorcycle ride around Mount Rainier

SoundRider has an article describing a trip around Mount Rainier which sounds like it would be fun.

I couldn’t imagine it without a map, so I plugged all the place-names into Google Maps and here’s what it looks like.

New electronics for Eva’s Flowerz

Eva’s big Flowerz sculptures from 2010 have been dragged out to Burning Man and to dozens of other events around Seattle over the last four years, and they’ve definitely taken a beating. My original electronics design was intended for a single, permanent indoor setup, so I’m surprised the lights survived being taken down and put back up in all kinds of environments as well as they have. They’ve gotten increasingly cranky, though, and now that half of them have died it’s definitely time for a replacement set.

LED and controller technology have come a long way since I designed the original lights. The new hardware is simpler, cheaper, and much more sophisticated; the new lights will have four times as many addressable pixels, so the animation space will now be two-dimensional (in polar coordinates) and not just a one-dimensional ring. What’s more, I had to individually hand-solder over a thousand through-hole LEDs for the old lights – there were dozens of tiny little wires running every which way. With the new system, the LEDs come mounted on strips of tape, all bussed up, so one control wire and two power wires are enough for eight RGB pixels. It’s AMAZING.

Stefan S. has been helping out with this project, and in just a couple nights of work we’ve finished all the soldering for two of the lights, with a lot of progress made on the other four. One more work session will finish the job. This is… I don’t remember exactly how many hours I spent on the originals, but it was in a whole different order of magnitude.

It’s a little bittersweet, opening up the old flower lights, tearing out what are now hilariously clunky, awkward, inefficient electronic devices that were nevertheless the very best I could do at the time, and replacing them with a project so simple it feels like cheating… but really, the hardware was always just a display for the animation algorithm, and that’s still the bit where the Art™ comes in.
