home, improved.

We reduced our mortgage payment considerably, just in time for the house to need some more professional attention. Long-awaited foundation work has come due, exacerbated by the weight of the solar panels and the new attic storage space. Naturally, the floor joist running the length of the house–most definitely load-bearing–has no piers under it. Construction in 1938 had a certain YOLO vibe to it, although in fact that arrangement has been Mostly Kind Of Okay™ all this time.

All that unused space under the load-bearing center floor joist was practically an invitation to install the furnace and ductwork there. In defense of contractors past, they knew enough not to cut into the joist, instead installing the shower drain backwards to compensate. (Our first plumber gave us a steep discount, saying "Don't worry about it. I'll be back.") The furnace is about due for a replacement, and the ducting is old and probably contributing to my allergies, sooooo maybe it makes sense to tear it all out. California passed some mighty restrictions on gas appliances; can we even replace the furnace with another gas furnace? What then, electric? What poor sod gets to make that work with the fresh electrical stuff from the solar panel install?

This is what the computing world calls a "yak shave."

(I'm not really sure who took the Yak Shaving idea from Ren & Stimpy and applied to computer programming, but now even American Express people use it.)

This is in addition to replacing the rotting fencing, adding gates to/from the neighbors' yards (they're lovely people, we like them), and finally creating a huge private space with GIANT GATES (and a human-size gate) across the driveway. It turns out that 20% of the property has been wasted all this time, and we barely know what do with it all. (Except to not build a small studio apartment: the permits were finally approved after 5 years, but jeez.)


The Fig Tree is untouched; we'd be happy to say goodbye to the Weird Apple Tree and the World's Worst Ornamental Pomegranate, but they're probably impossible to kill. For all I know, they share the same unholy root system as the Zombie Rose.

(Before our first summer here, we asked our professional plant guy friend to identify the trees. He said it was an Ornamental Pomegranate, that wouldn't produce much fruit. While he is great at his job, this is not remotely true of that tree, for which generations of opossums are grateful.)

Anna had the contractors move and level her tiny house trailer in the side yard, whereupon it emerged that the Thorny Lemon Tree over there had decided it wasn't done living, and had a respectable 2-foot-high revenant flourishing underneath the trailer, in the 18 inches of vertical space, closely surrounded on three sides by fences and structures from 7 to 15 feet tall. The fourth side gets maybe 30 minutes of dappled sunlight in the morning, peeking through the picket fence. The actually quite poor growing soil on our property appears to be like Pet Sematary for plants, because the Thorny Lemon, like its cousin the Zombie Rose, was actually dug up. Out of the ground. In 2013. Which is enough to kill most plants. But not ours.

And PG&E finally inspected the leased solar installation, so the house is 80-100% solar-powered on most days so far, because we live in a desert and also got the house-battery option. The phone app shows soothing animations of the power flowing one way and another, and tracks how much we use from each source. The lease arrangement provides a predictable price for electricity for the term...twenty years, maybe? With an option to renew. It may already be cheaper than PG&E, and it's sure to be so very soon. And more reliable, as PG&E escalates its "If you're just going to be angry when our lack of maintenance causes historic lethal wildfires, then we'll just turn off power to more and more people" strategy. (Last year their response to people who medically rely on electricity to live was, paraphrased, "Go fuck yourselves," and they're expected to steadily extend this policy into major metro areas.) 

It's Anna who really makes this sort of thing possible; I pay for stuff, occasionally lift heavy objects, and make sure the wifi works, and the rest is her doing. I mean, I'm exceptionally good at paying for stuff and making sure the wifi works, don't get me wrong. But her determination and project-management skills for this stuff are both waaaaaay better than mine. Not even in the same ballpark. Or playing the same sport.

stupid instrument.

I enjoy complaining about the violin, partly because it's like shooting fish in a barrel, but the truth is I'm pretty good at it, which is not so incredible, once you start grading on a curve. It's the same way a native English speaker like me with 3 years of studying French under their belt will be much more capable than the same person would be after 3 years of studying any form of Chinese.

(Unless you're Anna, whose natural aptitude with languages exceeds my natural and rarely-mentioned aptitude with weapons.)

Any teacher loves a student who wants to learn and will put the effort into it, and my teacher is no exception. It turned out we have a lot of tastes in common, particularly fiddle traditions, up to and including Scandinavian music, which is not for everyone––even I much prefer playing it to listening to most of it.

(Recall that the difference between a violin and a fiddle is that no one minds if you spill beer on a fiddle.)

And Baroque music, so I can play through a small Vivaldi concerto, and I was a bit off in the weeds being determined to play this Bach keyboard invention, so now I can play through it, too:

<iframe width="560" height="315" src="https://www.youtube.com/embed/1o8BXM3Wnbw" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

He does love a ton of standard violin repertoire that I don't, and I'll end up learning some of it anyway because that's what one does. I expect it will, again, be much more fun to play than to listen to.

Even though my 5-string covers the viola range, I've been eyeing violas for some time. Physics means my violin's 14" air chamber cannot produce the same sort of tone or volume as that of a viola. Apparently violas aren't acoustically perfect either, because if they were, they'd be too long to play.

(I've seen websites where builders complain about this, citing their own frustrations in arguing that 5-strings are pointless, which seems pretty obviously untrue. In particular, they vent about how the low G on a violin barely sounds okay, and the low C on a viola of any size is even less okay. It's worth noting that building a violin is not exactly easier than playing one, though I'm sure it's a quick transition once you've been building cabinets for a decade.)

Maybe we can blame Anders Hall, of Nordic Fiddlers Bloc and SVER, who makes folk viola look awesome. Anyway, I bought a starter viola––probably smaller than his, but who knows. (Violin sizes are standardized, if nonsensically named according to fractions having no relationship to any of the instrument's dimensions. Violas are categorized by body length, in half-inch increments.)

It arrives tomorrow! So we'll see.

stretched thin.

Back when my people were younger, we would often(-ish) go out to all-night electronic music parties of various stripes. I mostly stuck to and helped put on Chill Parties, but went to no few Dance Parties, and even more Campout Parties, and especially Campout Chill Parties. They customarily ended around dawn, so we'd help with cleanup, go home, and shower before going out to breakfast, followed by a day of watching TV.

(Nickelodeon launched a new satellite channel at the time, and its initial programming was literally nothing but Sesame Street, The Electric Company, and 3-2-1 Contact, a glorious undemanding parade of amusing nostalgia, perfect for being full of pancakes after being awake for 24 hours.)

The human body, even in our 20s, is not actually meant to be out partying until dawn, sober or not, so spending the day staring at Sesame Street is what we call "cracked out." I don't know where the term came from, but that's where I've been at this week.

I don't think I've ever been on a job search with this many conversations before, but the context-switching between companies, remembering who I've spoken to, when, and what I told them, is wearing me down. It doesn't help that all but one of these companies has around 10-25 engineers, all reporting directly to one of those two founders who are white or Asian guys with PhDs. Generally folks are pretty forgiving, but even so, you don't want to get the names wrong. The whole process has out-run my historical way of managing the notes and meetings of a job search.

I've been mostly angling to lead and build a whole Engineering department, to get some of the responsibility I want, without grinding my way through a larger company. PhDs have generally never hired people-leaders, so it's an exercise in mutual education: this past week, two companies who I'm pretty sure had taken that role off the table decided to put it back on. (I mean, sure, I'll be the only manager, call me a Director and we'll pretend I'm not running the thing.) For one of them, this manifested by passing me over to an executive search recruiter they'd retained after first talking to me. I had a great laugh with them about the context-switch thing, since of course they're dealing with even more companies at once than I am.

It's a good problem to have, but my stamina is running down, and I think I need to accept an offer before the end of the month, and in the meantime I'm just going to not respond to email for a few days.

eventful weeks.

I meant to take a photo of all the empty space on our lot: the garage looked nicer as a debris pile than it had as a garage, and yet it's even better now that it's all gone, and better still since our neighbors (who we're friends with) took down the shared fence. Even once we give them back the 8"-12" the old fence stole from their property, there's so much space to work with: not just the 19'x19' building, but the 6' wide Shed of Doom on the far side, and the metal-roofed, low-ceilinged, termite-ridden shade structure over the patio. There's so much space for things that are...not ugly! Someone on Nextdoor even wants the old well pump from 1955 or whenever.

In an improbable coincidence, the garage was demolished and then suddenly our permit to demolish+rebuild–which permit has been stalled for, no joke, 2 years–was approved. Not that any of us have the bandwidth for that, whether it's the project management, or the construction noise that we can't get away from because...there's nowhere to go. Instead, we'll put up a nicer shade structure, and a couple of sheds for secure bike and tool storage, and big gates across the driveway to screen everything from the street. It's gonna be awesome.

One thing startups don't like to tell young engineers is that any given startup, no matter how carefully they think they've chosen, is almost certainly not going to be the kind of success that will let them retire in luxury at 27. Silicon Valley relies on that heady brew of intelligence, optimism, ignorance, and heedless energy. Many of us keep working at startups even when we no longer have all of those things, because the money's good enough (depending on your lifestyle) and we don't like working at big companies. And there's a place for us, too. Or we hope so, as we get older.

This is not to say that companies don't find a way to "exit," as we say. The venture capitalists funding your startups are VCs because they're good at making money, for themselves and others. They know all the other VCs, who are also good at making money, and so it's not remarkably difficult for VCs to make money for each other–at the very least, to get their investment back–by buying each other's companies. If you own millions of shares, this can be a hefty down payment on your new Learjet; if you're an engineer who was employee #40, it will likely come out somewhere between "a weekend at the Four Seasons" and "buy a new Volvo." I've worked at a lot of startups–I think a dozen?–and all but the single most idiotic managed to fumble their way into a half-assed demise of being bought by Microsoft or Facebook or something. As a rule, VCs are good at getting paid.

I did manage to extract some real, non-hypothetical money from this last one, which means reserving money for taxes, paying off a lot of debt, and buying more musical instruments I've been eyeing for months or years. And probably adding to the list, since that is the way of things.

I've been mostly enjoying this round of job searching, which is new. I was a people-manager for 4 years at a name-brand company that everyone in tech recognizes, so I just have to talk fluently and convincingly about people and teams and organizations and relationships, which I can do easily, unlike programming interviews, which I can't. I'd already been unemployed for 3 months when the comically awful January struck, I'm pretty ready to stop looking and start working. I've been talking to so many companies, this week especially, that it's been hard to keep them straight, as I give similar answers to the same questions from different small companies on the same day. I'm happy to find places that value emotional intelligence (or would like to), and I'm expecting two or three offers to land next week, though, and then I can get busy hiring my Army of Dread Software Minions.

For my birthday I bought my first truly nice violin bow. It's carbon fiber, so far the only material to really compete with the incredibly problematic high-quality pernambuco wood that is still the musical standard. (Pernambuco is as messed up as any other tropical hardwood, and also it's even more wasteful than ebony, which is saying something.) This one has a funky kind of design and balance, which they suggest is for "high-octane" performances, perhaps well-suited to unusual instruments like my 5-string violin.

I love it. But I don't really understand why. I've measured and weighed and checked the balance points among the 3 very different bows I have: the carbon fiber, a yellow sandalwood, and a "hybrid" which is wood over a carbon fiber core. The differences don't look so big on paper, but our human power of honing our perceptions make these things matter. There's a story of an Olympic-level fencing match, where one fencer stops and accuses his opponent of cheating via a longer weapon. Sure enough, Mr. Cheaterpants's weapon was...1/16" too long. I don't think this is exaggerated: in aikido, I adjust my timing by fractions of a blink, maybe 50-150 milliseconds objectively. Get the timing wrong and your technique won't work.

So the new bow bounces "right," and seems to draw the right sound out of the instrument, including the low C string. I dunno. I just like it.

an architectural icon dissolves abruptly

One project that has been entirely too long-term has been to get rid of our garage, somehow, it being an unsafe structure and full of rats and termites.


Terrible Garage™
1938 - 2021
R.I.P.

The demolition took a day, and the cleanup will be longer: apparently, once you've created your pile of large smithereens, they lock together like felted fibers, and you have to further demolish the debris pile. As it is, they worked for 3-4 hours and filled a dumpster the size of our bedroom, and they'll fill at least one more.

Then some gates and fencing, some stuff for storage and some stuff for workshop space. It was really a huge chunk of the lot gone to waste, not only the 19' x 19'ish building, but 6 feet on one side, and maybe 3 feet on the other. (There's a tree back there!) We'd wanted to build a studio apartment for the kid, but it's been two years since we applied for the permit, and it's about time to give up and move on with other plans.

Thanks as always to Anna, who makes these things happen. ❤️

March 350th, 2020.

 One of the many,

many,

many

irritating things about the violin is that your ear is a few inches away from the soundhole, unlike the more civilized 1-4 feet given by...every other instrument. Playing generates a lot of little sounds and obnoxious harmonics that just aren't perceptible unless you have your head practically inside the instrument. Imagine the worst violin noise you've ever heard, and have some empathy for the poor player, who has it much worse.

(Low frequencies travel farther, and the gnarliest bits of violin sound are high frequency and low amplitude.)

Singers have the same problem, for the same reasons. If you try to sing so it sounds unambiguously good to you, you're almost certainly just bottling your voice up inside your throat and head, which are all full of resonating cavities and highly conductive bones bringing the sound to your ears.

(There are actually bone-conduction headphones, the wired version of which I tried out many years ago, and they didn't solve my problems, but they're cool and the sound is decent.)

You have to let your voice come out with some balance of nose and mouth. You can make some recordings to learn how you sound, take some lessons from a good voice teacher, and eventually you redefine what "good" means, so you can make it sound good for the audience, and you just spend less time sounding pretty for yourself.

All this to say that as I've been exploring my 5-string violin's viola capabilities, I've been wondering how it actually sounds. Putting a low C string on a violin––or a high E on a viola, for that matter––involves some funky and obscure design tradeoffs, between playability and the physics of tone. Some excellent makers have jumped right into the problem, with pricing around $6,000 at the low end, and $15,000-ish at the top (Jonathan Cooper, for example). That's a good deal for a pro-quality instrument, even if it illustrates the old adage that violin prices are like guitar prices, with an extra zero at the end. Mine was mostly made in (probably) China, and shipped to Gary in Minneapolis in some form. He took it apart if it wasn't already, added the electronics he invented, put it back together, and did the final setup of all the hardware bits: tailpiece, bridge, nut, strings.

(Having spoken with him at length, I would not be at all surprised if he checked all the front and back plate thicknesses, and did some re-graduating on them, as long as he had the thing in pieces already.)

Violas have a certain kind of growly tone, and I talked to Gary about what I was looking for: the punch of the lower register, with a pure but not strident upper register, since violin high notes kinda bug me. It doesn't have to look like an ordinary violin: I don't need to impress anybody, I'm not joining competitions or orchestras. I'm pretty sure my violin owes its rounded lower corners to a viola design I haven't had any luck finding, even though it's clearly a thing:

<iframe width="560" height="315" src="https://www.youtube.com/embed/1o8BXM3Wnbw" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

Although I guess I don't have any proof that Eric Benning didn't invent them.

Luckily, over the past year I've been accumulating the bits and pieces of a home recording setup: a couple of inexpensive microphones, a Scarlett 2i2 (a USB interface that connects microphones to a computer), and a pre-amp for the violin.

(I asked Gary the Violin Guy if I couldn't just plug the violin directly into the Scarlett like a microphone, and he said "Well, you can try it, but it's probably expecting an impedance like a microphone's, around 3,000 ohms, and the piezoelectric pickup's impedance is a few million ohms." So, right. Pre-amp it is.)

Maybe on a little bit of a lark, I bought another bow, nicer than my current ones. Bows and bow-making are far more arcane even than making instruments. For centuries the prized wood has been pernambuco, and I don't entirely understand why. Pernambuco is not doing better than every other tropical hardwood, and incredibly, it's even more wasteful than ebony, which is saying something. The primary replacement material is carbon fiber, which can certainly be achingly expensive, but for us mere mortals, you generally get a higher quality bow for the same money. I've been trying to not buy tropical hardwood stuff if I can avoid it, anyway. I got my other two bows re-haired so I could compare to the new one, and it's lovely, and I think quite suits my playing.

Attention Deficit HEY LOOK A SQUIRREL

Amidst the many-faced train wreck of the past few weeks, it emerged that I have Attention Deficit Hyperactivity Disorder (ADHD). This came up because I had an adrenaline-filled day at the end of December, and once I started digging into the problem, I found the adrenaline was granting me a state of hyper-focus that I haven't experienced in a long while. If your thinking is scattered, and a stimulant un-scatters you, well. We don't quite know why that works, but there it is.

This explains many long-running mysteries of my life: Why were my grades erratic when they could have been perfect? Why do I fidget? Why do tasks like taxes or bills go un-done, even when I know exactly what to do?

How and why do I read books the way I do? In the days of paper books, I would be in the middle of six or more books at a time, switching between them in a single sitting. E-books have taught me how many books I can actually be in the middle of and still remember the context when I pick one up: 20-30. I read some pages, flip to a different book, read some pages, change book, etc.

Why did I take a semester of Mandarin Chinese in college? I needed the stimulation of learning something difficult. Why didn't I continue with it? Because memorizing is hard for me––because it's boring––and learning Chinese is an endless vast quantity of memorizing arbitrary pieces of information. (I cannot recommend highly enough the self-descriptive essay Why Chinese Is So Damn Hard.)

ADHD shows up a little differently in super-smart people, in ways that are still being refined for the next DSM. One challenge is that the diagnostic criteria up to this point have included "If it makes living a fairly standard life impossible," so they're adding refinements to include "Can hold down a job, but causes a lot of suffering." And it's masked by being super-smart, which has let me lurch through a college education (albeit finishing with a 3.2? 3.4? GPA) and out into a successful career. If I weren't super-smart, I would probably be living in a van down by the river. Most likely an unregistered van, having failed to file the paperwork.

The difficulty of task initiation explains another life oddity: I'm terrible at mathematical proofs. Learning how the math works, using it to solve problems, I'm fine with; but if I sit down to try even the most basic proof (proving that √2 is irrational is the usual introductory example), I just can't get started. It's not math anxiety, as usually thought of; I just have trouble getting started. But I can, even now, explain the basics of differential and integral calculus, and I promise I've had only basic use for differential, and zero use for integral, since I graduated. Would I have learned them on my own? No. Is it fun to know them? Well, yes. I like learning and knowing stuff, and I'm really good at it. I have a long list of hobbies and random stuff I've learned, to prove it.

(While I was in Chile, Anna was driving J someplace, and he asked a question about the moon. She said, "I don't know, but I bet Chris would." To which J replied, "Yeah! Chris is like a Google, but one you can Skype!", which I think says a lot of true and wonderful things about our relationship.)

Anyway, yeah. ADHD. Possibly the easiest thing I've dealt with this month.  I do love a good theory that fits the facts.
