SSH access to the server that hosts my website has been down for a bit, which means I can't update it, but I did upload a bunch of things before that happened, and HTTP access is up, so you can still read/listen to them — you just won't find them on my songs index page.

Let's start with some new recordings of old songs...

I can't recommend this game enough. It hits a sweet spot between open-ended creativity and goal-directed challenge. The basic idea is that you build factories out of blocks (as many as you need, although you can compete to use as few as possible), and the factories receive input materials (which are blocks) and produce products (which are made of blocks), in order to serve our alien overlords. There's more than one way to complete every challenge, and figuring out the physics of the game is delightful. If this sounds at all intriguing to you, it's definitely worth a look.

Shelter and Shelter 2 on sale [Mar. 28th, 2016|07:41 am]

Shelter and Shelter 2 are video games in which you play, respectively, a mother badger and a mother lynx, and must care for your litter of young in a hostile world. They are both deeply discounted on Steam until tomorrow, and I think both are good buys at the sale price.

In both games the gameplay is disappointingly simplistic, but it's very much made up for by the gorgeous visuals, reminiscent of Eric Carle illustrations in 3D. I encourage you to check out the trailers and get the games if you think you'd enjoy romping through that visual world. If you want both, you can get them in a bundle on the Shelter 2 page.

A Jewish song for Pi Day [Mar. 13th, 2016|05:14 pm]

[Current Mood |bouncybouncy]

This song is not new, but I don't think I've ever discussed it in depth in this journal, and with Pi Day upon us it seemed like a good time.

So why a Jewish song about π? The claim is out there that the Bible claims that π is equal to 3 — years ago, I saw it come up on two Internet communities, rec.music.filk and a Quaker pagan list, at about the same time. Mostly it's presented in the context of "look, the Bible is wrong about science!" (if you want to show that the Bible is wrong about science, there are of course better disproof-texts than this).

Years later, at the Havurah Institute, I had the opportunity to join a study session with Adam Levine on the topic of what the Jewish tradition really says about π, and — remembering those newsgroup conversations — I jumped at the chance. I was not disappointed. This article cites essentially the same sources as Adam's handout if you want to delve deeper.

Out of that study session came this song (mp3), which I finally had the opportunity to share with Adam at last summer's Havurah Institute, to his profound delight. I hope you will find it just as delightful.

Some game reviews [Jan. 27th, 2016|09:58 pm]

[Current Mood |bouncybouncy]

Lately I have been buying a lot of video games from the Humble Bundle store — a website which started as a one-time deal (and co-created by a friend of a friend from Swarthmore) and has grown into an excellent retail outlet for Indie games. They often have sales (including right now), a portion of your purchase goes to charity, and a lot of the games are really good, so it's worth checking out.

There are a few games I've gotten recently that stand out enough to be worth a mention/recommendation.

Games that are on sale right now and for the next ~35 hours:


FEIST is an action game where you play a small furry creature in a quest to rescue another of your kind from troll-like beasts who have taken it captive. moreCollapse )

PixelJunk Shooter is an exploratory 2d shooter with a rich materials simulation — water and lava flow, water plus lava turns to steam plus stone, icicles drip, lava melts ice, etc. moreCollapse )

Last Horizon is a sweet little minimalist space adventure game where you maneuver a spaceship around and land on planets, lunar lander style. moreCollapse )

Games that are not on sale right now:


Mushroom 11 is not really like anything else. It's a platform game where you play as a sort of blob, and your only control is an eraser tool stolen from a painting program — moreCollapse )

Lovers in a Dangerous Spacetime is a (local) 2-player cooperative space shooter that reminds me a little of the board game Space AlertmoreCollapse )

ILD [Aug. 17th, 2015|09:59 pm]

[Current Mood |sillysilly]

The head of engineering at a major tech company has just come down to the shop to inspect the prototype of the company's latest model. On his clipboard is a checklist on which each feature of the device will be checked against the officially approved specification. And so far it all looks good — this is according to spec, and that is according to spec. But...

Scattered throughout the mechanism are little platforms, and standing on each platform are a few tiny demons standing at attention, singing sad songs and dirges and wailing and bemoaning their terrible fate. This is disconcerting, to say the least, and — what's worse — it's not in the spec.

The head of engineering turns to the build team and gestures at the tiny sad singing demons and asks, "What are these, and what are they doing here?" And the nearest build team member grins and says:

"Oh, those... I wouldn't worry too much about them — they're just imp lamentation details."

Tea-ball parade [May. 16th, 2015|09:57 am]

[Current Mood |happyhappy]

fiddledragon told me excitedly that she had seen a tee-ball parade across the street, but I heard "tea ball parade" and was momentarily confused, until I thought of this charming fictional tradition:

At the appropriate season, the townspeople gather in the square outside the herbalist's shop. Each person has a large tea ball on a string on a stick (like a fishing pole). People select herbs and flowers that symbolically represent a wish or prayer that they have (and that are non-toxic to aquatic life) and put the herbs in their tea balls. Then everyone marches together down to the river (this is the parade part), gathers at the shore, and steeps their tea balls in the current for an appropriate length of time. The wishes are believed to be carried down the river to the sea and out into the universe, where they may be fulfilled.

SQL haiku [Feb. 18th, 2015|09:18 pm]

At work there are some whiteboard walls. One of them used to be covered with puns, but recently the puns were erased and replaced with haiku. Since our company writes so much SQL, I thought it would be fun to contribute some haiku in SQL.

create view rainbow
as select distinct color
from meadow.flowers;

select count(flowers)
from meadow where wind is null
group by color, shape;

insert into heart
(select feeling from moment
where timestamp is null);


We also write an awful lot of Perl.

foreach $flower (@field) {
$rainbow{$flower->{HUE}}++ };
print sort keys %rainbow;
