Hi, I'm Eryn Wells. This is my website. Welcome!
## Latest
Here are some of my most recent posts.
{{< home/latest >}}
## Personal
I'm a queer trans woman, {{< tess >}}' partner, and mom of [two cats][cats]. I
was born in Seattle, {{< abbr Washington >}}WA{{< /abbr >}} and grew up in
Phoenix, {{< abbr Arizona >}}AZ{{< /abbr >}}. I attended [Oberlin College][ob]
where I got a degree in Computer Science. My pronouns are [she/her][pronouns].
You can read more about me on my [about][ab] page, or [get in touch][where-am-i].
## Professional
I've worked as a software engineer since 2011 for a variety of companies around
the San Francisco Bay Area. I joined [Apple][a] in 2016, where I currently work
on password management and authentication technologies.
My [résumé][r] has all the details.
## Hobbies
When I'm not working, you can reliably find me hacking on this website or [some
coding other project][gh]. I'm also a musician, and play piano, Irish tin
whistle, and modular synthesizer. Occasionally I [record][bc] [things][sc]. I
love outer space and astronomy; I will always get excited to look at the moon
with you, or check out anything through a telescope. I enjoy [photograhy][p],
mostly as a travel hobby. And I've been practicing iaido, a traditional Japanese
sword art, since early 2024. Other things I've been into include: bread baking,
bicycling, calligraphy, ceramics, and knitting.

{{< circular_image id=me name=me class="float-right" width=200
alt="Una foto de me, con sombrero, sentando en frente de un fondo de piedra">}}
Me llamo Eryn. Mis pronombres son [ella/ella][p]. Esta es me página personal.
Bienvenide.
Soy una mujer trans y queer. Vivo en San Francisco con mis [dos gatos][cats].
Nací en Seattle, WA, y crecía en Phoenix, AZ. Asistí [Oberlin College][ob] donde
obtuve un títolo en informática. {{< tess >}} es mi novia.
Mi lengua nativa es inglés, y también hablo español pero siempre necesito
practicar más.
## Pasatiempos
Tengo un gran apetito por probar y aprender pasatiempos nuevos, especialmente
las que combinan varias de mis intereses.
He sido música para el gran parte de mi vida. Empezé tocar el piano cuando tuve
siete años, toqué la trompeta en colegio, y he tocado algunos otros instrumentos
por el camino. Todavía toco el piano, pero mi obsesión musical hoy en día es mi
sintetizador modular. De vez en cuando, grabo música y espero compartirla aquí,
en este sitio. Por el momento, puedes escuchar mi música en [Bandcamp][bc] o
[SoundCloud][sc].
Otros pasatiempos de los años recients incluyen: cerámica, caligrafía, tejido,
horneado pan, ciclismo, fotografía, y astronomía. ¿Uno no puede tener demasiados
pasatiemos, de verdad?
## Trabajo
He trabajado como ingeniera de software desde 2011 por varias companías basadas
en San Francisco y Silicon Valley. Hace seis años que he trabajado en Apple,
primero en el equipo iOS Accessibility, y ahora en el equipo Authentication
Experience.
Echa un vistazo a mi [resumen][r] para más detalles.
## Decirme Hola
Puedes [encontrarme en muchos rincones del Internet][where-am-i]. Estoy más
activa en [Twitter][t] y [Instagram][i]. Publico música en [SoundCloud][sc] y
[Bandcamp][bc]. Y para los proyectos de software, estoy en [GitHub][gh].

{{% section class=content--small-right-column %}}
I'm Eryn. My pronouns are [she/her][p]. I'm a queer trans woman. I live in San
Francisco, CA, on the unceded ancestral lands of the Ramaytush Ohlone people,
with my [two cats][cats]. I was born in Seattle, WA and grew up in Phoenix, AZ.
I attended [Oberlin College][ob] where I got a degree in Computer Science.
{{< tess >}} is my girlfriend.
I speak English natively, and Spanish too, though I always need more practice.

## Hobbies
I've been a musician for most of my life. I started on the piano at age seven,
played trumpet in high school, and have picked up a smattering of other
instruments along the way. I still play piano occasionally, but my current
musical obsession is my modular synthesizer. I occasionally record things, and
I'm hoping to share them here on this site, but for now, they're on
[SoundCloud][sc] and [Bandcamp][bc].
I do try to spend my non-work time away from the computer, but every so often I
get inspired to hack on something. Those projects usually end up on
[GitHub][gh].
Other things I've picked up over the years include: ceramics, calligraphy,
knitting, bread baking, bicycling, photography, and astronomy. You can never
have too many hobbies, right?
## Professional
I've worked as a software engineer since 2011 for a variety of companies around
the San Francisco Bay Area. I've been at Apple since early 2016, first on the
iOS Accessibility team, and now on the Authentication Experience team.
Check out my [résumé][r] for more details.
## Say Hello
You can find me in [lots of other corners of the Internet][where-am-i]. I'm most
active on [Twitter][t] and [Instagram][i]. I post music on [SoundCloud][sc] and
[Bandcamp][bc]. I'm on [GitHub][gh] for coding projects. You can also send me an
[email][eml].

title: "Booting a Raspberry Pi Over TFTP"
date: 2020-10-13T08:31:52-07:00
description: A writeup of how I set up a Raspberry Pi to boot over TFTP to facilitate an operating system development project.
series: ["Raspberry Pi OS Development"]
categories: ["Tech"]
tags: ["Raspberry Pi", "Networking"]
---
In order to do this, I modified the [EEPROM bootloader][eeprom] bootloader
according to the instructions in the Raspberry Pi documentation. That page is
also on [GitHub][eeprom-gh] which might be a more stable location. On Raspbian
on the Raspberry Pi:
{{< figures/code >}}
```sh
fw=/lib/firmware/raspberrypi/bootloader/stable/pieeprom-2020-09-03.bin
rpi-eeprom-config $fw > ~/bootconf.txt
vi ~/bootconf.txt
rpi-eeprom-config --out ~/pieeprom-new.bin --config ~/bootconf.txt $fw
sudo rpi-eeprom-update -d -f ~/pieeprom-new.bin
sudo reboot
```
{{< /figures/code >}}
My updated `bootconf.txt` is:
{{< figures/code >}}
```cfg
[all]
BOOT_UART=1
WAKE_ON_GPIO=0
POWER_OFF_ON_HALT=0
DHCP_TIMEOUT=45000
DHCP_REQ_TIMEOUT=4000
TFTP_FILE_TIMEOUT=30000
ENABLE_SELF_UPDATE=1
DISABLE_HDMI=0
BOOT_ORDER=0xf412
```
{{< /figures/code >}}
I enabled UART debugging, and set the boot order to be: network `0x2`, SD card
`0x1`, USB mass storage `0x4`, and finally reboot `0xf`. These steps need to be
repeated if the bootloader is updated via apt.
I [enabled the TFTP server][mac-tftp] on my Mac:
{{< figures/code >}}
```sh
sudo launchctl load -F /System/Library/LaunchDaemons/tftp.plist
sudo launchctl enable System/com.apple.tftpd
sudo launchctl start com.apple.tftpd
```
{{< /figures/code >}}
Im not sure if the `enable` command is actually necessary. This doesn't
actually start the `tftpd` daemon. Instead, macOS starts the daemon on demand
when it notices an incoming tftp request on the network. Don't be alarmed!
The tftp server looks for files to serve out of **`/private/tftpboot`**, and those
things need to be world `rwx`, i.e. `777`. By default (this is configurable) the
Raspberry Pi queries for a directory named by its serial number.
{{< figures/code >}}
```sh
mkdir /private/tftpboot/$raspberry_pi_serial
chmod 777 /private/tftpboot
chmod -R 777 /private/tftpboot/*
```
{{< /figures/code >}}
Raspberry Pi looks for files of various names in that directory, one in
particular by the name of **`start.elf`**.
Next, I had to update my Ubiquiti router's DHCP server configuration (on the
command line) to pass a `tftp-server` parameter in the DHCP payload. This step
may be optional because you can also set `TFTP_IP` in the **`bootconf.txt`** above
to specify the IP directly. On my router:
{{< figures/code >}}
```sh
configure
set service dhcp-server shared-network-name LAN subnet $lan_cidr_subnet tftp-server-name $ip_of_mac
commit
save
exit
```
{{< /figures/code >}}
I also gave my Mac a static IP, and renewed the DHCP lease so it took the new IP
to make the whole process a little more smooth. Now, it appears the Raspberry
Pi will attempt a TFTP boot, and I see queries in the logs on my Mac.

{{< figures/image name=buchanan >}}
This past weekend, {{< tess >}} and I took a short, one-night staycation in San
Francisco's Japantown. With all the flurry of things happening in our lives, it
was so great to get away from home for a short time and relax.
We stayed at the [Hotel Kabuki][hk], a historic hotel in Japantown, and booked
time at the [Kabuki Springs][ks] bath on Sunday afternoon. We sat in the warm
bath, dunked in the freezing cold pool, sat in the sauna and steam room, and
lounged on the beds around the pools. The lights were low, the music was chill,
and it was so good to disconnect. This was my first experience in a communal
bath, and I left feeling like I wanted to go every weekend. (Tess and I are now
considering memberships.)
One of the wonderful things about a clothing-optional communal bath is the wide
variety of bodies you see. It was a great reminder of how diverse we are, and
how broad the definition of "woman's body" can be. I can't say for sure if Tess
and I were the only trans women there, but I think both of us came to feeling
like just one of the women there to enjoy the baths -- not out of place or
strange at all. It was a really great feeling.
We spent the rest of our time in 日本町 wandering the shops in Japan Center,
walking around the neighborhood, eating, and relaxing. For only being just over
24 hours away from home, I was impressed how much it felt like a real vacation.
Tess also [wrote](https://tess.oconnor.cx/2021/09/japantown) about our trip.

[Oskitone][oskitone] recently released a new synthesizer: the [Scout][scout].
It's a small monophonic keyboard synth built around an Arduino. It was a quick
build, and the result is tons of fun to noodle with. Here's a video of me
building the kit, set to music I wrote and produced with the completed Scout.
Enjoy!

{{< figures/image name=friends >}}
I'm writing this in the airport having just spend a week with a group of friends
who mean the world to me. For the past 18 months, we have been spending our
Monday nights on Zoom with each other. They've been an anchor of my week,
consistently one of the highlights, and a vital community during the COVID-19
pandemic, when I was often feeling otherwise isolated.
Way back at the beginning of the pandemic, we talked about getting together when
it wound down. Surely by August 2020, we all thought. Lol.
Nearly a year later, we started planning. Amazingly, we all made it through the
hours of calls devoted to AirBnbs and rental cars and the harrowing adventure of
traveling during a pandemic. We stayed together in Portland, OR for a few days
and then drive up the Olympic Peninsula to a grand old house in the forest. From
there we hiked and kayaked. We ate together and laughed and played music. We
finished our trip with a ferry ride to Seattle, WA.
I'm so grateful for every one of these people. We've been friends for years and
even though our lives have taken us in so many different directions, we've found
each other again and that is so wonderful.

## Portland
Our first weekend, we stayed in Portland, OR. We rented a great three-story
house on the north side of the city that was great for all 10 of us to hang out.
On our one full day there, we went to Powell Books and Deschutes Brewery.
On the way up, we all stopped in Olympia, WA for a break and some lunch. Some of
us stopped for oysters along the Hood Canal too. Our final destination was a
house in the woods outside of Port Angeles.
## Freshwater Bay
Our first day in Port Angeles we went kayaking on Freshwater Bay. We say river otters, sea
otters, and a baby sea lion! Our guide shared a bunch of cool stuff about the
kelp forests along the coast too.
## Hurricane Ridge
The second day we drove up to Hurricane Ridge where it was snowing. None of us
was really expecting such a dramatic change in weather. The snow was beuatiful,
but we were all a bit unprepared.
## Hoh Rainforest
The next day, we took a long drive around the Olympic Peninsula to visit the Hoh
Rainforest. We hiked through the Hall of Mosses, and along the Hoh River for a
while. We stopped along the riverbank to skip stones before heading back to our
cars. On the way back to Port Angeles, we took a short detour to Rialto Beach, a
rocky windswept beach covered in seafoam and driftwood. It was overcast and a
little foggy but beautiful.
## Lake Crescent
The last full day of our time in Port Angeles, we took a short trip to Lake
Crescent and nearby Marymere Falls. It was a short hike up to the falls. A
little rainy but nothing we couldn't handle.

This is my submission to the [Three Module Challenge][3mc] show put on by
Colorado Modular Synth Society in late January 2022. This is my first time
submitting a performance to a show like this, and I was super nervous. 🙈 I
persevered though and it was well-received. The hosts had [some nice
things][hosts] to say after too.
Submitting a video to a show like this is a nice way to dip your toe into
performing, without the stage fright that comes with doing it live in front of a
crowd. I encourage you to give it a go if you're interested in performing!

title: "Profiling ZSH"

description: In which I learn about how to profile my ZSH init files.
draft: false
categories: ["Tech"]
tags: ["ZSH", "Dotfiles"]
---
I've been hacking on my [dotfiles][dotfiles] a lot lately. One of the things
that has bothered me about my shell setup is how long it takes zsh to start up.
I did some research and found this [blog post][debug-zsh] from someone who
undertook the same project.
TIL, ZSH has a profiler built in. You can start it by calling the following.
{{< figures/code >}}
```zsh
zmodload zsh/zprof
```
{{< /figures/code >}}
Then, once you're done, you call `zprof` to get a report that tells you where
ZSH is spending most of its time. I put the line above at the top of my
`.zshenv` and then called `zprof` at the end of my `.zshrc`.
Over the years, my shell init has grown organically in various ways as needs
arise. I add things, hack around to make things work, and don't generally pay
attention to the overall structure of it. I've also frankly never spent a lot of
time to learn the quirks of how ZSH behaves, and the most efficient ways of
doing things. So, when I started this process, my init was taking close to a
second. By the end, it was down to about 100 ms. Not bad for a couple hours of
work. :)

Hace unas semanas que conecté a mi VPS para averiguar algo. Hay [un

iniciación de las sesiones de inicio de ZSH que imprime las sesiones existidos
de `tmux` asociados con mi cuenta. Me dio cuenta que había una sesión y me la
adjunté.
En esa sesión encontré un juego de [Nethack][nethack] que empezaba en enero y
nunca lo completé. Lo completé, me mató un duende, y, pues, el daño ya se me
estuve hecho.
Es posible que me entusiasme un poco.
{{< twitter user=erynofwales id=1510763278691016705 >}}
He mejorado mucho en las últimas semanas. Mis puntajes han crecidos desde 1,000
hasta el mejor juego hasta ahora en que [obtuve 9401 puntos][over9000]. Quién
puede decir si alguna vez ascenderé, pero me divierte mucho.
Incluso, me causa pensar en cómo puedo crear un roguelike de mi mismo... (hmmm)
Para diviertirme y porque soy un gran nerd, creé una página en este sitio que
auto-actualizará con los puntajas más recientes cada vez que yo publico mi sitio
web. Echa un vistazo a mi [logfile](/nethack) de Nethack para esa.

A couple weeks ago, I connected to my VPS to check on something. There's [a
part](list-tmux-sessions) of [my dotfiles][zprofile] that runs during login
shell initialization that prints the currently running `tmux` sessions
associated with my account. I noticed I had a session running and attached to it
to see what it was.
In that session I found a [Nethack][nethack] game that I'd started back in
January and never finished. I finished the game, killed by a Woodland Elf, and,
well, the damage had been done.
It has been three weeks and I've had at least one game of Nethack going on my
VPS or my laptop nonstop since then. There's been at least one Safari window
packed with [NetHackWiki][nethackwiki] tabs too, including a pinned one for the
[Price Identification][priceid] page.
I may have gotten a little carried away a time or two.
{{< twitter user=erynofwales id=1510763278691016705 >}}
I've gotten much better in that time. My scores have increased from the
1000-2000 range to my best game so far in which [I scored 9401
points][over9000]. Who's to say if I'll ever ascend, but I am having a lot of
fun with it.
It's even got me thinking about building roguelikes... (hmmm)
For fun and cause I'm a huge nerd, I put together a page on my site that will
auto-update with my latest scores each time I publish the site. Check out my
Nethack [logfile](/nethack) for that.

I've been playing a whole bunch of Roguelikes lately. Here's a short list of games I've really enjoyed.
### Nethack
[Nethack][nh] is the first roguelike I ever played. There were a bunch of students in my Computer Science program at
Oberlin that were always playing it in the CS labs.
Most recently, it's what got me hooked on the genre all over again. Famously, it gives you almost nothing to go on when
you start. It's up to you to figure out everything based on what you -- the player -- know about the game. It's like a
puzzle!
{{< figures/image name=nethack >}}
### Brogue
[Brogue][b] is the first Roguelike I played after only ever playing Nethack. The first time I started it up I was in
awe. It does a really great job of making use of the terminal to render a beautiful world for you to explore. The water
(there are lakes!) animates, there are fields of mossy grass and plants, there are blobs of goo that explode and spread
noxious pink gas everywhere.
{{< figures/image name=brogue >}}
### Dungeon Crawl Stone Soup
My friend David introduced me to [Dungeon Crawl Stone Soup][dcss] on Twitter. I think it does a good job of distilling
the complexities of many roguelikes into a simpler form that's still rich and engaging. I really like how easy it is to
drop in on people and observe games too!

title: "Making an Audio Scope with P5.js"
date: 2022-08-18T20:48:37-07:00
description: A writeup of a small JavaScript waveform visualizer I made with P5.js.

{{< audio id="amen" mp3="amen.mp3" >}}
This is a quick write-up to share with y'all a small project I've been working
on using [P5.js][p5] and [Web Audio][webaudio] to implement some audio
visualizations. By the end, we'll have something like this:
{{< figures/p5 id="oscilloscopeFinal" bordered=1 >}}
## Embedding an Audio File
HTML has the ability to [embed audio][mdn-audio-tag] in a page with the
`<audio>` tag. This one declares a single MP3 file as a source.
{{< figures/code >}}
```html
<audio id="amen">
<source src="amen.mp3" type="audio/mpeg">
</audio>
```
{{< /figures/code >}}
In this form, the `<audio>` element doesn't do anything except declare some
audio that can be played. It's invisible and the user can't interact with it or
control playback. That fine because because I'm going to implement my own
playback control as part of my sketch below.
## Processing Audio with Web Audio
Web Audio uses a node-based paradigm to process audio. Audio flows from source
nodes, through a web of interconnected processing nodes, and out through
destination nodes.
Sources can be `<audio>` tags or realtime waveform generators; processing nodes
might be filters, gain adjustments, or more complex effects like reverb; and
destinations could be your computer's speakers or a file.
Here's the entire code snippet that sets up the audio processing I need for the
sketch:
{{< figures/code >}}
```js {linenostart=2}
let analyzerNode = null;
let samples = null;
let audioElement = (() => {
return document.querySelector('audio#amen');
})();
let audioContext = (() => {
const audioContext = new AudioContext();
const track =
audioContext.createMediaElementSource(audioElement);
analyzerNode = audioContext.createAnalyser();
track.connect(analyzerNode)
.connect(audioContext.destination);
return audioContext;
})();
```
{{< /figures/code >}}
The [`AudioContext`][mdn-audio-context] is the object that encapsulates the
entire node graph. On line 10, I create a new `AudioContext`.
On line 11, I create a [`MediaElementSourceNode`][mdn-webaudio-media-source-tag]
with the `<audio>` element I declared on this page.
Next, line 13 creates an [AnalyzerNode][mdn-analyzer-node]. Analyzer nodes don't
affect the audio that flows through them. Instead, this node gives the sketch
access to the raw audio samples as they're passing through the AudioContext.
We'll use this to plot the waveform as the audio is playing!
Line 15 hooks up the nodes in the graph. We connect the output of the source
node to the input of the analyzer node, and the output of the analyzer node to
the audio context's `destination` node that routes to the computer's speakers.
Our audio processing graph looks like this:
![](diagram.svg)
By itself the AudioContext doesn't actually play any audio. I'll tackle that
next.
## Playing Audio
Next up is starting playback. The following snippet creates a Play button using
P5.js's DOM manipulation API, and hooks up the button's `click` event to start
and stop playback.
{{< figures/code >}}
```js {linenostart=29}
const playPauseButton = p.createButton('Play');
playPauseButton.position(10, 10);
const playPauseButtonElement = playPauseButton.elt;
playPauseButtonElement.dataset.playing = 'false';
playPauseButtonElement.addEventListener('click', function() {
if (audioContext.state === 'suspended') {
audioContext.resume();
}
if (this.dataset.playing === 'false') {
audioElement.play();
this.dataset.playing = 'true';
this.innerHTML = '<span>Pause</span>';
} else if (this.dataset.playing === 'true') {
audioElement.pause();
this.dataset.playing = 'false';
this.innerHTML = '<span>Play</span>';
}
});
```
{{< /figures/code >}}
Something I found odd while working with these audio components is there isn't a
way to ask any of them if audio is playing back at any given moment. Instead it
is up to the script to listen for the appropriate [events][mdn-audio-tag-events]
and track playback state itself.
If this snippet looks a little convoluted, that's why.
To track playback status, I decided to set a `playing` property on the button's
`dataset` indicating whether to call `audioElement.play()` or
`audioElement.pause()` and to set the label of the button appropriately.
The last bit of playback state tracking to do is to listen for when playback
ends because it reached the end of the audio file. I did that with the `ended`
event:
{{< figures/code >}}
```js {linenostart=53}
audioElement.addEventListener('ended', function() {
playPauseButtonElement.dataset.playing = 'false';
playPauseButtonElement.innerHTML = '<span>Play</span>';
}, false);
```
{{< /figures/code >}}
This handler resets the `playing` flag and the label of the button.
## The Sketch
Now it's time to draw some waveforms! The main part of a P5 sketch is the `draw` method. Here's mine:
{{< figures/code >}}
```js {linenostart=57}
const amplitude = p.height / 2;
const axis = p.height / 2;
const blue = p.color(24, 62, 140);
const purple = p.color(255, 0, 255);
p.background(255);
if (analyzerNode) {
analyzerNode.getFloatTimeDomainData(samples);
}
for (let i = 0; i < samples.length; i++) {
const sampleValue = samples[i];
const absSampleValue = Math.abs(sampleValue);
const weight = p.lerp(2, 12, 1.5 * absSampleValue);
p.strokeWeight(sampleValue === 0 ? 1 : weight);
p.stroke(p.lerpColor(blue, purple, absSampleValue));
p.point(i, axis + amplitude * sampleValue);
}
```
{{< /figures/code >}}
The most interesting part of this function starts at line 66 where we get an array of samples from the analyzer node. The `samples` variable is a JavaScript `Float32Array`, with one element for each pixel of width.
{{< figures/code >}}
```js {linenostart=30}
samples = new Float32Array(p.width);
```
{{< /figures/code >}}
Once the sample data is populated from the analyzer, we can render them by
plotting them along the X axis, scaling them to the height of the sketch.
I also manipulate the weight (size) of the point and its color by interpolating sizes and colors based on the value of the sample.

title: "Hugo's Dictionary API"
date: 2022-10-13T10:19:02-07:00
description: Ive found Hugos API for collections to be difficult to understand. Heres my attempt to summarize its quirks.
categories: ["Tech"]
tags: ["Hugo", "Web", "API Design"]
series: "Erynwells.me Development"
---
Hugo's templating system has support for dictionaries. Unfortunately the API for
working with them is, frankly, awful. While working on developing some new
templates for this site, I had to figure out how to build up dictionary data
structures and it took me a _long_ time to figure out how to do some basic
operations with them.
Here's a quick summary of what I found.
## Creating Dictionaries
The function to create a dictionary is called [`dict`][dict] and it takes a
variable number of arguments that alternate between keys and values. It reminds
me of this [bizarre and backwards NSDictionary API][nsdictionary-init] in Apple's
Foundation framework. Keys must be strings (or string slices) and values can be
anything. So this:
{{< figures/code >}}
```go-html-template
{{ $d := dict "a" 1 "b" 2 "c" 3 }}
```
{{< /figures/code >}}
creates a structure that looks like this JSON object:
{{< figures/code >}}
```json
{ "a": 1, "b": 2, "c": 3 }
```
{{< /figures/code >}}
You can also create an empty dictionary by calling `dict` with no arguments.
{{< figures/code >}}
```go-html-template
{{ $d := dict }}
```
{{< /figures/code >}}
## Accessing Keys and Values
Statically, you can get a single item in a dictionary with dot syntax. Below,
`$item` will get the value 1.
{{< figures/code >}}
```go-html-template
{{ $item := (dict "a" 1 "b" 2 "c" 3).a }}
```
{{< /figures/code >}}
If you want to get a value with a key you get at render time, you can use the
[`index`][index] function. In the snippet below, `$item` will get the value of
`"b"`, which is 2.
{{< figures/code >}}
```go-html-template
{{ $key := "b" }}
{{ $item := index $key (dict "a" 1 "b" 2 "c" 3) }}
```
{{< /figures/code >}}
`index` doesn't make much sense to me as a verb for accessing values in a
dictionary. It sounds more like an array function, and indeed it's the function
that gives you access to items in arrays. I would like to see another function
with a more dictionary-sounding name, like `get` or `value` or `item`, even if
it were just an alias for `index` underneath.
## Adding Items to a Dictionary
This is a bit complex because, as far as I can tell, dictionaries are immutable.
So, if you want to update a dictionary, you need to combine two dictionaries and
then save it back to the original variable. The [`merge`][merge] function does
that. Here's a snippet:
{{< figures/code >}}
```go-html-template
{{ $d := dict "a" 1 "b" 2 "c" 3 }}
{{ $d = merge $d (dict "b" 4) }}
{{ $item = index "b" $d }}
```
{{< /figures/code >}}
`merge` takes a variable number of arguments, and merges dictionaries left to
right. So, items in dictionaries later in the argument list will override items
in dictionaries earlier in the list.
Just to underscore, you have to set the update dictionary back to the original
variable to complete the update, hence the `$d = ...`.
All that is to say: at the end of that snippet, `$item` will get the value 4.
## A Complex Example: A Dictionary of Arrays
For the previously mentioned template changes I was making, I was updating the
`terms` template for my category taxonomy. For each category, I wanted to show
one section per tag, and a list of all the posts with that tag underneath.
My categories are high level groups like "Tech," "Music," and "Travel." Tags are
more specific topics for the post like "Web" or "Compositions." Pages only ever
have one category but they can have multiple tags.
A `terms` template lets you access an array of terms, and the pages associated
with those terms. You can access the tags attached to a page with the
`.GetTerms` function. Here's what I did, and then I'll talk through it:
{{< figures/code >}}
```go-html-template
{{- $pagesByTag := dict -}}
{{- range $page := .Pages -}}
{{- range $tag := .GetTerms "tags" -}}
{{- $tagName := $tag.Name -}}
{{- if not (in $pagesByTag $tagName) -}}
{{- $pagesByTag = merge $pagesByTag
(dict $tagName (slice $page)) -}}
{{- else -}}
{{- $pagesForTag := index $pagesByTag $tagName -}}
{{- $pagesForTag = $pagesForTag | append $page -}}
{{- $pagesByTag = merge $pagesByTag
(dict $tagName $pagesForTag) -}}
{{- end -}}
{{- end -}}
{{- end -}}
```
{{< /figures/code >}}
`$pagesByTag` is my empty dictionary. It will hold tag names as keys, each
pointing to a slice (array) of page objects. For each page, I get its list of
tags. For each tag, I check `$pagesByTag` to see if it already has a key/value
pair for that tag. If not, I create a new entry in `$pagesByTag` with `merge`.
If it does already, I get the slice for that tag with `index`, add the Page to
the slice with `append`, and then merge the updated slice back into
`$pagesByTag` with `merge`.
It's not too bad once it's all spelled out, but it does feel like more work than
it should take for such simple operations.
I think this API could be improved substantially with some new functions that
operate specifically on dictionaries and that have clear names that describe
what they do.

description: A quick note about the upcoming lunar eclipse in the morning of 2022-11-08.
categories: Space
tags: [Moon, Lunar Eclipse]
---
I shouldn't be surprised (but I am) that the lunar eclipse happening tomorrow
morning has [its own Wikipedia page][wp]. It won't be visible at all from most
of Europe and Africa, but it will be from most of North America, and on the west
coast of North America, we'll be able to see it all. Yay!
All the times on that page are in UTC. Here are some handy conversions (in 24-hr
form) to PST for those of us on the US west coast:
| Contact | Time (PST) |
|:--------:|:----------:|
| P1 | 00:02 |
| U1 | 01:09 |
| U2 | 02:16 |
| Max | 02:59 |
| U3 | 03:41 |
| U4 | 04:49 |
| P4 | 04:56 |
If these times make no sense to you, the eclipse starts at roughly midnight
tonight, the total eclipse is between 02:16 and 03:41, and it ends at 04:56.
More information about contact points for lunar eclipses can be found in the
Timing section on the Wikipedia page for [Lunar Eclipse][wp-le].

I just finished my best ever game of Nethack. I earned 31,118 points as a level
9 Valkyrie.
Some highlights:
I got all the way to the bottom of the Mines, fought several vampires and
trolls, but somehow completely missed the luckstone. I did pick up a grey stone,
but it ended up being a touchstone.
I got a Wand of Wishing! I was zap testing wands in Minetown and the game asked
me for a wish! I had no idea what to wish for -- it was my first time getting a
wish 😱 -- but I had been watching [Adeon's Nethack speedrun][adeon] at the 2017
Roguelike Celebration and remembered him wishing for some absurdly qualified
dragon scale mail, so I ended up with a *+2 uncursed silver dragon scale mail*
that brought my AC down to -10. It saved my butt later on when I ran into a
bunch of winter wolf pups because it reflected their cold beams.
{{< figures/image name=wishing >}}
Later on in the mines, I stepped on a polymorph trap that transformed me into an
ice dragon. That transformation caused my dragon scale mail to fuse into my
body. When the transformation ended, I was left with simple dragon scales,
which were still silver, but no longer had the big defense bonus. Boo. :( I did
get to lay two eggs that hatched into baby ice dragons. Baby dragons are
ravenous and indiscrimate.
The baby dragons killed the Oracle. Whoops.
{{< figures/image name=oracle >}}
In the oracle level, I tried to dip my long sword into the fountains around the
Oracle, hoping to find Excalibur. Just a few turns before, I'd fought a
gelatinous cube that corroded my sword. I didn't notice at the time though, so
dipping went horribly wrong... Not only did my corroded long sword become
*thoroughly rusted*, it also eventually became cursed. Oddly enough, that sword
was still the best weapon I had, and I used it to the very end. I need to figure
out how to replace weapons that get degraded like that.
I solved Sokoban with some help from the Nethack wiki for the first time. The
puzzles are hard but I enjoyed thinking through them. The monsters in there,
especially in the upper levels are *hard*: multiple elementals, several packs of
winter wolf pups, yetis, apes, and a zruty. I got through the last level and
discovered a mimic blocking the hallway to the zoo. It killed me.
Near the end, I was testing amulets and put on an Amulet of Changing that caused
me to switch genders. Boo.
It's in my [logfile][logfile] now too.

A kind reader pointed out to me that my Atom feed was incorrect. There were two
problems. First, I was specifying an incorrect URL in the feed's `<link
rel="self">` -- it was pointing to a nonexistant feed.xml file. Second, I was
omitting a `<link>` tag from the entries entirely.
Thunderbird didn't like this. With no `<link>` for an entry, it would show the
feed's `<link>` in it's UI. And that link left users at a 404 page.
I pushed a fix this morning. You might have to refresh or resubscribe to pick up
the changes.

I started [playing a lot of chess][chess-post] recently. As often happens with

I found the mostly excellent, occasionally vague and confusing [Chess

this on it's [Getting Started][cpgs] page:

As a software engineer, the "bug free" bit cracks me up.
My engine is called ChessFriend. It uses [bitboards][cpbb] for its board
representation. As of this post, I've managed to write a board representation
that allows me to place pieces of both colors on any square, and I'm hacking
away at the move generator. I've also written a small command line "board
explorer" utility that can interact with my board representation. Of course, it
has a pile of unit tests, helping me inch ever-so-slowly toward that blissful
bug-free state.
It's written in Rust. I've [_mostly_][rust-bc-toot] avoided fighting with the
borrow checker.

Should I Blog About?][what-to-blog-about] post too.
My vision since I started posting more here has been to use it as a place to
share all sorts of things: stuff I'm working on or thinking about; photos; and
stories from travel and life.
I often fall into a trap when I sit down to write something in which I feel like
I must first invent the Universe. The need to explain everything from first
principles seriously hampers my ability (and frankly, desire) to write anything.
I don't want to only post carefully thought out, highly edited and polished
pieces, though I certainly hope _some_ of my posts reach that bar. I hope to
also post quick notes and sketches of ideas. I've enjoyed reading some quicker
posts from {{< tess >}} and [Elaine][e] this past year, and I'd like to follow
their example.
{{< youtube zSgiXGELjbc >}}
I'm not setting myself a specific goal here. The idea is just "more" in a
certain general direction. I don't want to commit to a specific frequency or
quality. Instead, I'm hoping this post sets a foundation on which to build a
sustainable thinking-writing-sharing habit.
Thanks for coming along. :)

I finally got around to replacing the Twitter icon in the site's header with a
link to my Mastodon page. It was surprisingly tricky because of how I styled and
layed out those icons. I was able to clean up the SVGs a little bit too.
These days I have [way too many social media accounts][where-to-find-me]. I'm
mostly on Mastodon and Instagram.

While browsing {{< r nethack >}}, I came across a [post][post] from someone sharing a [collection of AI-generated
images][guide] that illustrate the story arc of a game of Nethack. Between the images and the prose they added around
it, I thought they did a fantastic job of capturing the mood of the game.

Last week, I published a small blog post about trying to find the original
[Netscape "meteors"][meteors] loading animation. At some point that night,
someone posted it on the orange website, and ... it did some numbers.
As of today, five days later, my server has registered just over 200,000 page
accesses.
{{< figures/code >}}
```txt
% grep "GET /blog/2023/08/netscape-meteors/" \
/var/log/nginx/access.log | wc -l
200201
```
{{< /figures/code >}}
Bandwidth saw a bit of a spike too.
{{< figures/image name=bandwidth-2023-08-05.png shouldShowTitle=false >}}
To my knowledge this is the first time anything I've published on the internet
has been picked up by Hacker News. It's jarring to realize so many people have
visited my website in the last several days, reading this and other things I've
written, listening to music I've published, and looking through photos I've
posted. It's a little like having surprise house guests and realizing you
haven't tidied up in a little while.
I only took a brief look at the comments. I was pleased to see they were civil,
and mostly reminiscing about the days of Netscape and the early web. I had a few
people reach out to tell me they enjoyed my post too.
Thanks, y'all, for reading my little corner of the web, and for your kind
words.

I went on a small journey the last couple days to find the original Netscape
Navigator "meteors" animation. This one has a special place in my head and
heart because it is so clearly connected to my memories of discovering the
web as a kid. Here it is in its original 60&times;60 px glory:
{{< figures/image name=netscape60 shouldShowTitle=false size=small >}}
I started out doing some web searches that turned up several versions. One was
promising but far too big: 400&times;400 px. Worse, after some shoddy resize
attempts, the "pixels" had become rectangular.
{{< figures/image name=rectangular-pixels shouldShowTitle=false size=small >}}
This would not do.
I continued searching, hoping to find the original animations. I found someone's
[mirror of Netscape 5.0 on Github][gh-netscape]. Then I found some [very old
versions of Mozilla][moz-netscape] on a Mozilla FTP server. Sadly, the
animations had been stripped out of these archives. :(
Frustrated with hitting several deadends, I complained to {{< tess >}} and
wondered aloud if anyone might have the original images stashed away somewhere.
She quipped that if anyone did, it would be Jamie Zawinski.
A little later, I posted about it on Mastodon.

class="mastodon-embed"
style="max-width: 100%; border: 0"
width="400"
allowfullscreen="allowfullscreen">
</iframe>
And wouldn't you know it, a friend tagged [`@jwz`][masto-jwz] asking if he had
it, and a few moments later I got a reply from [Jamie][jwz] himself.

allowfullscreen="allowfullscreen">
</iframe>
If you don't know, Jamie Zawinski is well-know for working on several important
software projects in the '90s. He worked on Netscape Navigator, built and
maintains [Xscreensaver][xscreensaver], and several other things. Nowadays, he
owns and runs [DNA Lounge][dna] in San Francisco.
There are a lot of neat bits of web browser history on the page he linked --
totally worth a quick look over -- but most important to the quest at hand, it
had that Netscape meteors loading animation.
The original one has some small artifacts on the left side of frame 10 that
render as red and orange pixels. These bothered me enough that I made a version
that replaces those pixels with ones that match the surrounding pixels. Here's
the modified 60&times;60 one and a bigger 240&times;240 px one, for good
measure:
