tracks and traces

Another busy and fun week.

I’ve been remiss about blogging my experiences at the Recurse Center, so I will try to make up for lost time here.

Using San Francisco Muni’s NextBus API, I collected a day’s worth of data on the movements of light rail vehicles and made a Marey style diagram of their movements.

I’ve been blogging less frequently about my garden in year 2, but it is proving much more succesful.

Recently, I was planning a not-too-wise east bay cross country hike, and I leaned pretty heavily on orienteering maps for planning purposes.

Over an approximately 2 year period.

I needed to have an easy way of communicating with the Stanford language parser.

Wrote a little Python (too) late last night to scrape and munge some tide station data from NOAA: The result:

Today, Chris introduced me to an open source alternative to SolidWorks for parametric modeling, OpenSCAD.

“Hello, would you like to share something you’re hopeful for in your community?”

After reading an image off a Heimann thermopile array, the pixel values can be converted to temperature readings through the use of calibration parameters stored on the device.

Last week, I needed to add many axes to a single D3 svg.

I received the sensor that I purchased from Heimann Sensor a couple weeks ago, and today was able to succesfully read an image off of it.

I2C what it mean: http://www.ti.com/lit/an/slva704/slva704.pdf address of device seems to be 0x1A and not 0x34 as reported by datasheet via i2cdetect: pi@raspberrypi:~ $ i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: – – – – – – – – – – – – – 10: – – –

This is cross-posted as a research note on the Public Lab.

A conversation on a mailing list inspired me to re-gender the first presidential debate.

This seems like an incredible quantity of food.

Working on a project with Python and Selenium to scrape a bunch of images from Facebook.

Yesterday, I talked about how to build a custom map project in proj.4 and mapnik.

Installing mapnik and linking to a custom, self-compiled proj.4 library I manually compiled proj.4 from downloaded source code.

Wavy-leaved paintbrush (Castilleja applegatei.)

Group by date: db.getCollection('images').aggregate( [ { $group: { _id : { month: { $month: "$datetime.utc_timestamp" }, day: { $dayOfMonth: "$datetime.utc_timestamp" }, year: { $year: "$datetime.utc_timestamp" } },

In this post, I’ll show how we can use Julia and my multi-scale image decomposition library, Pyramids.jl, to implement Phase-Based Frame Interpolation for Video, an algorithm from CVPR 2015.

n.b.

I went for a walk around Glen Park today, trying to find miner’s lettuce, a supposedly delicious salad green that grows wild in the area.

We arrived back from Southern California at 3am Friday night, and I immediately bee-lined for the garden.

Lemonade sumac Really sticky berries.

Finished porting some code for generating complex steerable pyramids from MATLAB to Julia.

A slow fade back to San Francisco.

I expanded my Photo display React component to display groups of photos, and provide a user interface for expanding and contracting them. !

I spent today working on a Stupid Hackathon idea, shamelessly stolen from Tom Brown, that sadly did not get built at the event itself.

I woke up this morning to find that the freshly planted patch in the back of 1611’s back yard had been completely dug up, and around the edges, suspiciously sized footprints.

Tilling the clay-y soil of 1611’s Great Dead Patch, with a little help from friendly-cat.

I woke up not feeling so great this morning.

What is a loquat?

Gradient descent, for kittens!

In May, I co-organized San Francisco's "first" Stupid Shit No One Needs and Terrible Ideas Hackathon, along with my friends Will Doenlen, Rachel Fong, Joshua Horowitz, and Noah Swartz.

Maddie would be easy smile to know.
