Day 29 – Bluebird Skies

finch: (Default)

Not the library I was at today.

It’s Wednesday! I’ve done four complete weeks. It feels like I just started, to be honest. Today started early, as I had a follow up doctor visit to make sure I was recovered from last week’s “event.” I knew I wanted to make today’s prayers at the library before I even went to sleep last night, though, and I had my bag packed with the books I needed to return.

The morning was gray and wet and windy, and no amount of cover helps much when the rain is blowing sideways. I got some quality solo train time in, which hasn’t happened much since we moved. Along the way I took care of some paperwork that needed to be done and visited Portlandia for the first time in a while. It had lightened up some by the time I was walking from the train stop to my office, but it stayed gloomy and damp right up until about an hour before my shift ended, when the clouds thinned and the blue spring sky came through.

After work I was practically skipping on the walk to the library. For the last Wednesday, my offering was joining the Friends of the Library, a proper commitment to the town and the library wights as well as an offering for Pillai.

I need to spend some more time with the new lesson from the Court of the Work In Progress but it’s got me thinking about my writing, and the spirits I already work with and the spirits I could turn to for help with that. The course has thus far done an amazing job of happening to be just what I need when it comes into my mailbox, I have to admit.

One last day with Pechak and Velos and this experiment will officially be complete, though I have to finalize the prayers and their format. And now that I’ve laid this groundwork, it’ll be time to move onto the next thing.

Today’s coin is an Algerian 1 dinar coin. The back features a prominent star and crescent symbol and a hamsa. The star reminds me of the Dark Lady, and the crescent I hadn’t used to associate with her, but pairing her with Monday has made me think about it. I hadn’t spent enough time with Redbird to see it before the last few months, but the Dark Lady and the Bright Lady are very much two sides of the same coin. The hamsa is a protective symbol, so this coin I take as the Dark Lady’s blessing.

Those of you who love Open Source Bridge: it's going to be June 20-23, in Portland, Oregon. The call for session proposals closes in a few days, on 31 March. Last month Denise mentioned she hasn't yet decided whether to treat OSB 2017 as a "take Dreamwidth people to this conference" conference. But regardless, figured you might want to know.

Changes this year: a Community Organizer track during the Friday unconference, more extracurricular activities, and "a new track to explore how activists are using technology, how open source communities are supporting activists, and how other open source and activist communities intersect."

Presentations, panels, sets of lightning talks, workshops, or other session types are welcome.

Presentations can fit either a short- or long-form slot. Short-form presentations will receive a 45 minute session, and long-form will have 1 hour and 45 minutes. Pick the format that best fits the scope and style of your presentation.

It's been a tough week at work; not so much on matters of complexity, but rather on sheer volume. With last week's cluster and cloud computing, there has been in an influx of over two hundred master's level students to the HPC system and the inexperience of quite a few is evident. Such is the effects of an entire generation of computer users who have started with the GUI rather than the command-line. Apropos the planned session with the good folk at the University of Freiburg didn't get up for the International Supercomputing Conference. A German co-author responded pithily, You have to see that we are considered heretics. Well, it wouldn't be the first time, that's for sure. So instead we're looking at a publication in Advanced Computing. Given that most of the paper is already written, a draft can be submitted perhaps the end of next week.

Shortly after that [livejournal.com profile] caseopaya, [livejournal.com profile] funontheupfield, and I are heading to New Zealand. Apparently I can't get enough of the place. The latter has never been before so recommendations were put in place for a short trip; Wellington and the Marlborough Sounds, primarily Havelock and Collingwood with opportunities to take short hikes, go spelunking, horse riding, and to see the strange natural landscape that is Farewell Spit. Given that my past two trips to NZ have been almost entirely work-related, I'm rather looking forward to the opportunity to venture 'cross The Ditch entirely for pleasure. Hopefully I will be able to organise dinner in Wellington for the handful of people that I know there.

The native animal population at our home has had a recent increase with a clutch of friendly young magpies deciding that our home is worth a visit, primarily for cat biscuits. A few days later a blue tongue lizard decided to move in. We think it's still in the house somewhere. Our other animal companions however have not been particularly perturbed by our new visitors; apparently our home is an open-plan zoological garden. I must however express some concern with the health of Tramper the rat. Already close to three years old (about ninety in rat-years), he's doing it a bit tough. He's had a bumblefoot infection for a long tiome (which curiously, seems to be healing up), he has a large mammary tumour which is quite inoperable without risk to his life, and now he's has advanced glaucoma in one eye. Tramper now spends much of his time snoozing (even on the rat-scale of things), but also has a good appetite and enjoys scritch time. Despite his illnesses, I think he's going to be around for a few more months.

More parser theory

simont: (Default)
[personal profile] simont
I had a conversation recently about low-priority prefix operators in infix expression grammars, which left me mildly uncertain about what they ought to mean. So here's a quick straw poll.

Suppose I have an expression grammar in which the multiplication operator * and the addition operator + have their usual relative priority (namely, * binds more tightly, i.e. is evaluated first). Then suppose I – perhaps unwisely – introduce a prefix operator, which I'll call PFX for want of a better name, which has intermediate priority between the two, so that

  • PFX a + b behaves like (PFX a) + b, i.e. the PFX is evaluated first
  • PFX a * b behaves like PFX (a * b), i.e. the PFX is evaluated second.
That's simple enough (if unusual). But things get weirder when PFX appears on the right of another operator. Specifically, what would you imagine happens to this expression:
a * PFX b + c
in which you can't process the operators in priority order (* then PFX then +) because the PFX necessarily has to happen before the *.

In what order should the parser process those operators?

Day 28 – Lemon, It’s Tuesday

finch: (Default)
[personal profile] finch
Tuesday’s dollhouse shrine figure. Clothes are still a work in progress.

Every week Tuesday has rolled around and I’ve somehow been sans prayer, despite having working models for everyone else, despite being completely sure I’m going to work on it this week.

On one hand, considering I knew almost nothing about Tuesday when I started, the fact that I now can contact him, interact with him, and know the outline of his mythology seems like some pretty good work to show for it.

On the other hand, well.  I hadn’t actually done the assignment. I started with the format anyway, planning to make something up on the fly as I had last week and promising myself that later on I’d do it properly, maybe following the format from Felix Warren’s course, or doing some meditative writing or something.

Nope. Sit.

He made it clear that I was going to sit there and I was going to write the damn draft, and despite getting distracted by a goose (goose necks are weeeeird y’all) and worrying about rain, I got it down. As a bonus, I got a few more notes on his personality, and a vocabulary edit. (Instead of “worker for my household” I’m experimenting with “voice of my household”. What do you think?)

Tomorrow morning I have another doctor’s appointment, because I think Wednesday is the only slow day at work that I haven’t had one yet. Maybe I have. I’d have to check my notes.

Anyway. I decided to pull a coin again tonight, and this time it was a commemorative coin for the 1996 Olympics with the logo for rowing on it. (Does anybody else remember those? They came in cereal boxes and I was obsessed with collecting them.) Sometimes you just have to keep plugging along, and sometimes plugging along hard enough is what wins you the medal.

Miscellany

kareila: Ariel in human form, regaining her voice (ariel)
[personal profile] kareila
We did see the Beauty and the Beast remake with the kids on opening weekend, and the general consensus is that it was great. The original holds a special place in my heart and just hearing the opening theme makes me tear up, so I am by no means unbiased, but I was also not in the mood for an exact reproduction. I needn't have worried, though - there were several story tweaks and a handful of new songs. My voice expert friends lamented EW's obvious lack of vocal training, but apart from a touch of autotune here and there (most audibly on the Beast's new song), I didn't notice anything that took me out of the moment. I do still lay awake at night wondering about Chip, though. (Either he has been a teacup for basically his entire life, or he hasn't aged. Either way: not OK, enchantress lady.)

On Friday, one of the local public libraries had their bimonthly game night, which my kids have embraced as an opportunity to try new board and card games that they've never played, but have usually heard about. (Connor is an especially avid watcher of Wil Wheaton's Tabletop videos). This time we were introduced to Exploding Kittens, which was silly and fun - I'll definitely be adding it to our collection in the future.

Last night was our first rehearsal with the conductor for the Verdi Requiem. I was expecting to see Carlos, our principal conductor, but instead we were introduced to his current backup, a shockingly young Asian woman. Although she was engaging and charming, she clearly lacked experience, and now I'm worried about Carlos. My first thought was that some sort of scheduling conflict must have come up, but then I started hearing rumors that he was facing some sort of major health challenge, which I sincerely hope is untrue. He's about my age, with very young children, and he's been in the position for less than two years.

Day 27 – Dark Lady 

finch: (Default)
[personal profile] finch
It was never really about the candles. Even when I was lighting them every night for Mara, even when it was the only thing I seemed to be able to do, it wasn’t the candle that mattered. It was the remembering to do it. The attention. The energy they represent can be offered in other ways.

Representation and symbology is at the heart of not just sympathetic magic but many other techniques as well. I’ve been thinking about this off and on. Much of what I’ve been doing from Project Protagonist on has been about figuring out what symbols resonate for me and what they mean – not for other people, or according to this or that source, but what clicks in my head. Frankly, the more I play with divination systems, the harder a time I have with popular systems like tarot and runes.

I was reading this post on divination systems from Kylara earlier and her system of charms reminded me of the Magpie Oracle, which reminded me of the Found Objects oracle (the link for which is unfortunately offline) which in turn reminded me of Felix Warren’s Road Bones.

I feel better when I can point to the chores I’ve done. I feel better without the daily “frog” hanging over me. (And I know Bug’s been watching a lot of Doc McStuffins… I feel better, so much better, thank you Doc for taking all the ouchies away.)  This isn’t perfection and it doesn’t have to be, after all. Systems like the road bones and the found object oracle are meant to be actively changing systems, just like us. Pieces join. Sometimes pieces leave. The symbols we need in our lives change over time. Father means something very different now than it did five years ago.

I pulled a coin from Mara’s bag tonight. It was a charm from an old tourist attraction that reads “Frontier Town USA Salutes the Man of the Past.” A lot of the pieces in the Calvinbag set, as I’m calling it in shorthand, are pieces I’ve had since I was a kid. They have layers upon layers of meaning thanks to my past selves. I know at a touch which of those star charms represents space and science and which represents magic and fae and yet it’s only the current me that can draw the connection between them and conclude that stars represent knowledge.

The Dark Lady reminds me that this evolution is necessary and important. Who I am in the dark has never been who I am in the light, and both of those people are constantly changing. I am a shapeshifter, after all.

You know what's super annoying? Not knowing the ip-address of the server you're trying to access. I could scan the network and find the right machine. But, I'm lazy. And, the server knows its own ip, it should simply tell me.

This is something I believed my Pirate Radio could manage. When the pHAT BEAT bonnet gets installed it sets itself up with a daemon in /usr/bin. Technically I installed it twice (once for spotipy as well). I don't know if the code differs, but as I installed vlc-radio last, that's the code I will play with.

Think it through. I've just booted up the server. The volume and power buttons do very necessary jobs, so we'll leave them alone. The fast-forward and rewind buttons start playing a station/cycle through stations. Very useful if you can't be bothered finding the ip-address. That leaves Play/Pause, which doesn't do anything until a station has started streaming. And if I have access to the web interface, well I can do that very job there. That's it, I'm sacrificing Play/Pause!

In the end I simply replaced line#204 with a call out to my script;
myip.read_ip()
(making sure to import it at the top of the file. Let's hear it for the wonders of Open Source!)

What script you ask? A simple one, to parse the wlan0 ip from ifconfig, and then a call to text-to-speech to actually read it out loud to me.

You'll probably need to install the text-to-speech stuff;
sudo pip install pyttsx
sudo apt-get install espeak


Then save this as a file named myip.py (or whatever) into /usr/bin

#!/usr/bin/env python

import os, pyttsx, time

def read_ip():
f = os.popen('ifconfig wlan0 | grep "inet\ addr" | cut -d: -f2 | cut -d" " -f1')
your_ip=f.read()

engine=pyttsx.init()
engine.say(your_ip)
engine.runAndWait()

time.sleep(3)
print your_ip

if __name__ == '__main__':
read_ip()


And sure, give it a reboot to make sure the changes are picked up.

Now, when I press play the Pirate Radio reads out its ip-address to me! So handy.
(Note; if you press play with monitor and OTG cable attached, it'll probably crash and reboot. So don't do that.)

Day 26 – Bright Lady

finch: (Default)
[personal profile] finch
Incense and candles are a good all-purpose offering, but I’m fascinated by the variety of things individual powers might prefer. An all-in day for Redbird included:

teaching sex ed to my sunday school kids

receiving the blade-in-chalice ritual of my regular testosterone shot

grocery shopping

spending the afternoon off the computer, taking care of little things around the house and playing with Bug

a spectacular home-cooked meal from my spouse

Basically she wants me to live in the moment and be committed to doing the best I can with what I have. Sometimes that’s medical care and sometimes that’s a nap and sometimes that’s finally getting a shoe rack put together in the entryway.

Hail the Bright Lady, who shines light on my choices. Do what you do with intent, whatever you do.

It seems kind of hard to believe that the month is almost over. It’s definitely time to be finalizing the daily prayers. I’m not sure whether I’ll type them up and make a little booklet for myself or copy them neatly into a notebook but either way they’ll be getting a ‘final’ version so I don’t have to keep flipping forward and back in my bullet journal every night.

Pimoroni Pirate Radio

chebe: (Purple - DanceLikeNooneisWatching)
[personal profile] chebe
Hardware
Order the Raspberry Pi Zero W Pirate Radio (get it?) kit.
Assemble. Making sure you put the headers on the correct way around *cough*.

Software
Download the NOOBS installer. Extract archive. Copy contents to microSD card of 8GB+.
Put microSD card in Pi, supply power to boot. (You will need a monitor (micro HDMI), OTG micro-USB adapter to plug in keyboard and mouse.)
When boots into installer connect to wifi. (Have the details handy, you'll need them again later.)
From the network install list select Raspbian Jessie Lite.
Lite boots into console only (you can do away with the mouse now). Default login deatils are; pi/raspberry. You'll need to edit a config file to connect back to wifi;
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
And add;
network={
ssid="YOURSSID"
psk="YOURPASSWORD"
}

Once online, install all your favourites (*cough* vim *cough*). Now is also a good time to set up the Pi as you want it. For instance, change the hostname;
sudo hostnamectl set-hostname new_host_name
You'll also need to update the hosts file;
sudo vim /etc/hosts
And update the line that says;
127.0.0.1 raspberrypi

You can test the speaker with;
aplay /usr/share/sounds/alsa/Front_Center.wav

Spotipy
Okay, so far so good. But, it's supposed to be a radio yeah? Do you have Spotify Premium? Then you can hook it up, with a convenient one-line installer;
curl https://get.pimoroni.com/spotipy | bash
It will install a whole load of things (details here), asking for your input (including Spotify login details), and then reboot.

From another device you can access the web interface at http://192.168.0.2:6680/iris/ (run ifconfig on the Pi and take the ip address from the wlan0 interface). You'll need to go to the Settings tab and Authorize your Spotify account. Ta-da, that's it, rock out.

(But, it seems the installer doesn't actually remember your Spotify details properly, so open /etc/mopidy/mopidy.conf, down the bottom check that the [spotify] section contains your username and password. It had forgotten my username and mangled my password, so definitely check.)

(Also, your session will timeout regularly, just log back in, no worries.)

VLC
But, I was not content with just Spotify. I wanted actual internet radio. So I installed the vlc-radio as well.
Again, just one line installer;
curl https://get.pimoroni.com/vlcradio | bash
You can access the web interface at http://192.168.0.2:8080 (default login details; blank username/raspberry).
If you want to queue up your own internet radio stations save them as playlist.m3u, and scp over to /home/pi/.config/vlc/. Then reboot.

(SSH server is off by default, you can turn it on through sudo raspi-config, more details here.)

Other than warning you that the default volume is very high, that's it. Enjoy!

I need refills on all my drugs, but I'm tired of dealing with my current pharmacy. Their logistical skills, which have always been sub-par, have lately gone in the toilet.

Last time I went to get refills they told me the wait would be an hour. It used to be 45 minutes, but an hour is fine too, time to go get dinner and come back. I get back and get told not yet, 20 more minutes. So I wait, and go up to the counter again and get told 30 more minutes and I say screw it I'll pick it up tomorrow.

My pharmacy before that one no longer exists. (RIP Target pharmacy bottles.)

I transferred all the scripts to another pharmacy, closer to my house. It was relatively trouble free, so far. But the one thing I can trust my current pharmacy on is complete disinterest in my drugs; very few pharmacies are quite so nonjudgemental.

There's also the one script I never bothered to get the prior auth approved for. That self pay price has ballooned from $40 to $600. I'm not even sure I want to take that one anymore; maybe I'll just get surgery and be done with it.

The drugs only change when the doc changes. They all want me on them indefinitely, forever. But no 10 year supply, nope, docs love a short leash.

The first unit nurse I ever had called our medication 'drugs'. I was 12, the rest of the kids not much older. We loved it. The tshirt that had the Olympic rings made out of colored condoms didn't hurt, too.

Day 25 – A Dark Night

finch: (Default)
[personal profile] finch
It’d be a bit more thematically appropriate on the Dark Lady’s day, but Mondays are very bad days for minor spiritual breakdowns so Saturday is a perfectly fine choice. We were at the church tonight for social time and I stepped away after dark to call to Tzymir there in the darkest part of the yard.

Maybe it’s just because it’s Saturday and I get so little response from him, but when my kid woke up screaming from a nightmare, I found myself laying with her in the dark wondering if I was even accomplishing anything with this work, and then if the fact that I was wondering about it made me feel I hadn’t accomplished much at all toward  unpacking my hangups regarding warding.

I think, intellectually, I have made progress. I know I’m doing more and asking for more overall. But tonight I feel like I’m wandering aimlessly in Tzymir’s labyrinth and I’m not sure how to get out. Gonna ask Redbird in the morning if sleep doesn’t help.

Sarah Jane maintains the Dr Who tradition of companions making dubious fashion choices.


I was first amused and then subsequently puzzled by the copyright notice under the picture. This is, after all, a publicity still created with the intention that it would be copied and published by other people.

At any rate, I'm assuming that at this point in the game I'm a) too small a fry a b) people distributing publicity images on the Internet is too common a thing for the BBC to come after me, but I suppose we shall see.

Day 24 – Craft Time With Brhenti 

finch: (Default)
[personal profile] finch
The to-do list project is to-doing along. It’s not perfect yet but I’m trying to be more aware of how I’m spending my time. 

Friday is for Brhenti, so after dinner and playing with Bug it was project time. I decided to try this easy plan for making a tote bag from a t-shirt (verdict: super easy!) and then started on some hand stitching. 

Jewelry is really a thing I need to work on at my desk because of all the small pieces and pliers and things, so I’m liking the experiments with things like sock darning and hand sewing that I can do on the couch with the family, and pick up or put down easily depending on what’s going on. 

We’re far enough into this project now that I have pretty solid prayers for everyone. I’m making daily offerings but they vary depending on who they’re to, and that seems sensible. 

There’s been a lot of medical foo and illness this month, though, enough that I’m wondering if that means I’m still fucking up something in the warding process. Of course, it’s also been widely acknowledged in town that there’s been more and worse winter bugs than usual this year, so maybe I’m being paranoid. 

I haven’t actually celebrated the equinox yet, and that actually is a holiday – we should be celebrating Mara’s return from her winter hunt now. Oops. Frankly I think I lost track of it because I knew Easter was so far out. I found a bread recipe that I want to try but I need to find the yeast. 

Not an exciting Friday, but I’m looking forward to the weekend.
