I had my first counseling appointment today, which seemed to go well, and will hopefully help me deal with the various sorts of stress I'm now facing. Speaking of stress, yesterday I made a reservation to see my parents on June 3 - June 7, which pleases me not at all, but seems useful for keeping the peace. I'm considering skipping GenCon this year simply so that I don't have to visit them again.

In happier news, when I was walking to the bus stop, I saw someone walk by with an awesome t-shirt that said "My pronouns haven't even been invented yet", which made me happy and seemed a good omen for the day. I got home and googled that phrase, and found the above link to buy the t-shirt, along with that fact that it's by genderqueer activist, poet, and spoken word artist Andrea Gibson, who I'd never previously heard of before, but looks to write very shiny stuff.

Here's a spoken word piece of their's that I found quite powerful:
Also, in honor of national poetry month, here's one I found online that I quite liked.

Floating Point Precision

IBM 360/44:

One unusual feature of the Model 44's console was a rotary knob to select floating point precision; reducing the precision increased speed.

Funny story: this is actually how it's implemented in Javascript to this day.


Bizarrely, the units on the knob are bits in the significand, divided by 4. For comparison, modern floating point would be a setting of 6 for single precision and 13.25 for double precision.

The second console function was "operator intervention":

program debugging tasks such as examining and modifying memory or registers and setting breakpoints. The Model 30 console controls below were used for operator intervention. To display memory contents, the operator selected an address with the four hexadecimal dials on the left and pushed the Display button, displaying data on the lights above the dials. To modify memory, the operator entered a byte using the two hex dials on the far right and pushed the Store button. (Although the Model 30 had a 32-bit architecture, it operated on one byte at a time, trading off speed for lower cost.) The Address Compare knob in the upper right set a breakpoint.

If IDE developers were as obsessed with skeuomorphism as music software developers, this is what Xcode would look like:

Maybe that's not such a bad idea, actually. Xcode should have Winamp skins.

SOMA Nature Walk: Cistern Edition

I thought this was cool: as a part of the interminable Central Subway construction, they have re-paved the intersection of 4th and Bryant, but that was more complicated than usual, because there's a cistern there. It's 75,000 gallons, built in 1908, and even though it's probably concrete rather than brick by now, it is still traditional for them to be marked with a ring of bricks. That meant framing it out with two different circular molds and two or more concrete pours over a couple of days.

You see a lot of sloppy road-work in this town, but not when it comes to pouring curbs and bulb-outs. That's when they do the work to get their cosines and Béziers right.

On the other hand, the pour for the new curb you can see across the street has been half-done for so long that grass has begun to grow in the exposed dirt.

I finally got around to watching The Umbrella Academy on Netflix, after hearing lots of mostly-positive comments and reviews. Naturally, I must now share ALL OF MY OWN COMMENTS AND REVIEWS. Such is the nature of the internet…

I mostly enjoyed it, though the ending felt empty and unsatisfying.

Details behind the spoiler cut…

Catching up on baseball, half-listening while I do other stuff. But I couldn't help but snap to attention when I hear one of the commentators say "Pitchers are out there shagging..."

Yeah. It doesn't mean the same thing in baseball as I'm used to hearing it mean now that I live in the UK.

"My early 20s was all about 1950s vintage librarian looks (fit n' flare dresses, patterned tights, cardigans) but in the last year (legitimately writing this to you on my 30th birthday), I've found myself leaning towards a much more androgynous style."

Weki Meki to have a May comeback!

Yay!  Weki Meki, one of my favorite (if not my very favorite) K-pop groups, will be having a comeback in May!  I can't wait to see and hear what they come up with this time!  (I'd been thinking recently that they were due for a comeback soon, and apparently I was right on track.)  Expect to see further updates on this here, as the agency teases us with photos and video clips to build up expectation before the big day.

Novel Excerpt

Part of a hard SF novel about the first extra-solar colony. (Yes, I've been working on this for a long time. Hard SF is, indeed, hard.)

"Here's our set of inspection gauge blocks," said Goose, presenting the case and opening it as if it contained someone's crown jewels. "Top quality ceramic, with a guaranteed accuracy of one part in half a million."

"Well, as long as they don't take up too much of your volume and mass allowance."

"Waide, there are several other things I would leave behind before doing without these," said Goose, flatly. "In a very real sense, engineering is measurement. With these and some other tools I'm packing we'll have durable, accurate standards for length, mass, volume, temperature and time." 

"Excellent," said Waide, nodding. As a physicist he certainly understood the need for accurate measurement and good standards. Waide eyed the engineer for a moment, reluctant to ruin his good mood, but he had to settle something important. "You're still over on your mass and volume limit."

"Not any more," said Goose, surprising him with a triumphant smile. "I got Daviess to agree to drop the drill rig. Had help from Sammies, who pointed out that we would be a long time there before needing petroleum and it would be far easier to find water on the ground than to drill for it. I mean, if there wasn't surface water near our landing site we wouldn't land there. That should also save us quite a bit of money and mass."

The Junction station of the Yellow line would replace a block ripe for upzoning. Credit: Sound Transit

Elevated light rail alignments in West Seattle have a unique problem. Unlike any other part of the system so far, they run through a built-up, residential area. Planned or existing lines are lie mostly in existing right-of-way, or tunnel into their own.

Sound Transit has had to demolish some housing for other projects, mainly at the periphery of neighborhoods. But one of the proposed elevated West Seattle lines, the Yellow/West Seattle Elevated line, would require bulldozing unprecedented parts of two built-up neighborhoods: Youngstown (the northern end of the Delridge area) and the Junction.

Residents have taken notice, forming the East Alaska Junction Neighborhood Coalition (EAJNC), a community group whose site says they “support and look forward to the arrival of a new Link Light rail extension in our area but have concerns about the proposed plans.”

In a letter EAJNC sent to Sound Transit as part of the environmental impact scoping period, the group estimates that the Yellow line would “require the demolition and taking of well over 100 properties” and would cause “substantial negative impacts on at least 50 to 100 more.” The letter includes a map showing, by EAJNC’s reckoning, what buildings would need to be demolished in order to build the alignment.

For their part, Sound Transit estimates that the end-to-end alignment would be the “lower performing” of the three alignments under consideration in terms of “properties potentially effected,” “potential residential unit displacements,” and “potential business displacements.”

In other words, the Yellow line would require the most buildings to be knocked over out of the three lines—though it’s important to remember that the score also includes impacts in other neighborhoods along the line, like Chinatown-International District and Ballard.

In the scoring document, the agency estimates that “more than approximately 180 potential residential unit displacements” would be necessary to build the line, with demolitions “primarily in the Delridge neighborhood and between Avalon and Alaska Junction stations.”

The disparity isn’t limited to the two documents, or even to the Junction. At a recent public meeting, Youngstown residents accused Sound Transit of lowballing the amount of units that would need to be demolished to build an elevated line through their neighborhood. In that meeting, West Seattle’s City Councilmember, Lisa Herbold, questioned project director Cathal Ridge about the disparity.

Most of the buildings the EAJNC letter refers to are single-family homes. However, the alignment would be extremely close to a number of apartment buildings, as the letter indicates. Sound Transit’s conceptual visualizations of the Genesee and Avalon intersection show the Yellow line station nearly abutting the Altamir building. A smaller inset map shows the station covering the southeast corner of the Altamir. The complex has 157 apartments, a mix of one- and two-bedroom units; a Petco; and a QFC.

The visualizations leave the fate of Altamir and other multifamily buildings ambiguous. Some buildings farther down the hill to the east are pictured, implausibly, immediately below the Avalon station.

But there is no doubt that the station’s location would eliminate a large swath of land that could hold dense, affordable housing instead of a guideway. The entire block bounded by Southwest Oregon, Southwest Alaska, 41st Avenue Southwest, and 40th Avenue Southwest would have to go to the Link station and guideway.

Other parts of the surrounding parcel in the immediate walkshed of the station would also be blocked by the guideway. In fact, the chance that the final alignment might take the land out of play was the reason that Herbold removed the relevant upzones from the HALA package earlier this year.

Indeed, Sound Transit’s scoring of the Yellow line also points out that the line offers “limited equitable development opportunities in West Seattle compared to West Seattle Tunnel Alternatives because elevated alignment results in fewer large surplus lots.”

Regardless of the impact of the Yellow line on present housing, an elevated guideway and station would, by definition, limit developable land within the walkshed. One of the critical goals of Link expansion is inducing transit-oriented development—but the Yellow line would do the opposite. To stay within budget and create a viable elevated option, Sound Transit needs to get creative.

I've got to confess to being rather surprised by this one.  BabySoul is a member of Lovelyz, and if you had asked me I wouldn't have guessed that any of the members of the group had a voice capable of pulling off a song like this.  Don't get me know - they all have decent voices, but they all seemed better suited for group work than for soloing.  At any rate. I'm pleased to have been mistaken.

The video is kind of unusual for K-pop videos, in that BabySoul doesn't appear in it at all.  Usually the opposite is true - the videos are so performer-centric that no other people appear.  It suited the song, though - I found myself wondering what the guy was waiting for.  Did he know she was coming back, or was he just hoping?  For that matter, is she coming back?  Once the English subtitles are available, I'll probably have a better idea, but for now all I've got is questions.

Also, if the comments to the video are accurate, BabySoul also wrote the song herself, so hats off to her for that.  (It could be my imagination, but K-pop idols writing their own songs seems to be becoming more common, particularly in solo and subgroup releases.)

(As for Lovelyz, their last comeback at "Lost N Found" on November 26 of last year, so they're due for a comeback but not overdue.)
