Inspired by Manton Reece, who was inspired by Derek Sivers, I too will include on this page what I’m thinking about and working on right now. This page will be updated semi-regularly as seems appropriate. The post date reflects when this was updated, and all Now pages will be archived and linked to from this page as regular posts as they are, themselves, updated. Here we are in 2020 facing down COVID-19 and expecting to spend the next several weeks if not months primarily at home.

A vision of the future from the 1980s, racism in America, cities lose their potent power as engines of mobility, and Robert A. Caro's continued genius.

Better Worlds is a series of 10 original science fiction stories commissioned by The Verge. Contemporary science fiction often feels fixated on a sort of pessimism that peers into the world of tomorrow and sees the apocalypse looming more often than not. At a time when simply reading the news is an exercise in exhaustion, anxiety, and fear, it’s no surprise that so many of our tales about the future are dark amplifications of the greatest terrors of the present.

There’s No Shortcut to Wisdom A good read on Adam’s decision to dive away from reading as much philosophy as he can get his hands on and instead begin diving into fiction and poetry. While I share his view that he has “set [himself] up to argue with the Jamesons rather than the Geoghegans”, and believe me this is worth reading just to appreciate that line, I am decidely less optimistic than he is on the power of the humanities and literature to reveal truth.

A lot of people in my life are trying to diversify who they read. I know I’m doing poorly on reading people of color, but I felt subconsciously like I read quite a few books by women. So I decided to check the last three years of books I’ve read. I exported my data from Goodreads as a CSV 1, hand coded the authors, and found, to my surprise, I was now reading mostly women.

A quick inventory of things I currently subscribe to (prices per year): Washington Post ($48) Netflix ($132) Hulu ($144) DirecTV Now (mostly for my mother-in-law) ($180) Amazon Prime ($99) Spotify ($180) Overcast ($10) Setapp ($120) Six Colors ($60) Digital Ocean ($60) Slate Plus ($59) Micro.blog ($60) iCloud Drive ($120) The Incomparable ($60) Feedbin ($30) Backblaze ($60) Total: $1,422 I think I might be missing a few things. The overall cost there is not insignificant, but I have a hard time knowing what I’d cut.

The Yoda of Silicon Valley ↬ When Knuth chooses to be physically present, however, he is 100-per-cent there in the moment. “It just makes you happy to be around him,” said Jennifer Chayes, a managing director of Microsoft Research. “He’s a maximum in the community. If you had an optimization function that was in some way a combination of warmth and depth, Don would be it.” Imagine being described this way?

When I think about the legacy of politicians, I think about the growth of my personal political consciousness. It is hard to show up for every issue, harder still stay ahead and find ways to hold the right views, right-away all the time. Reflecting on my own growth, I have almost never regretted or changed a viewpoint that was informed primarily by exercising maximum empathy. Now I try and lead with this wherever possible, and I hope this heuristic means I make less mistakes.

I tried to make a point today at an AEFP panel on weighted-student funding that came out all wrong. We were discussing the differences between school-based autonomy and fiscal equity via WSF. Too often, it was being argued, these two concepts come together. This serves to hold back on achieving equity (potentially) if districts are unwilling/ready to provide greater school-based autonomy (or don’t believe in that model for better resource decision-making).

Ideation At the start of every project, there’s a blinking cursor. Actually, that’s almost never true for me. If I start staring at a blinking cursor, I’m almost guaranteed to keep looking at a blinking cursor, often for hours. The real work almost always starts weeks or months before I actually type anything. I think it’s easy for folks for whom their ultimate product is a bunch of code or an analysis report to undervalue that our work is creative.

I have some text, but I want the content of that text to be dynamic based on data. This is a case for string interpolation. Lots of languages have the ability to write something like pet = "dog" puts "This is my {#pet}" pet = "dog" print(f"This is my {pet}") There have been ways to do this in R, but I’ve mostly hated them until glue came along. Using glue in R should look really familiar now:

I have been using ggplot2 for 7 years I think. In all that time, I’ve been frustrated that I can never figure out what order to put my color values in for scale_*_manual. Not only is the order mapping seemingly random to me, I know that sometimes if I change something about how I’m treating the data, the order switches up. Countless hours could have been saved if I knew that this one, in hindsight, obvious thing was possible.

Looking back on 2017, there were three major trends in my R code: the end of S4, directly writing to SQL database, and purrr everywhere. The End of S4 The first package I ever wrote extensively used S4 classes. I wanted to have the security of things like setValidity. I liked the idea of calling new as it felt more like class systems I was familiar with from that one semester of Java in college.

My latest project at work involves (surprise!) an R package that interacts with a database. For the most part, that’s nothing new for me. Almost all the work I’ve done in R in the last 7 years has interacted with databases in some way. What was new for this project is that the database would not be remote, but instead would be running alongside my code in a linked Docker container.

I have not yet spent the time to figure out how to generate a JSON feed in Hugo yet. But I have built an R package to play with JSON feeds. It’s called jsonfeedr, and it’s silly simple. Maybe I’ll extend this in the future. I hope people will submit PRs to expand it. For now, I was inspired by all the talk about why JSON feed even exists. Working with JSON is fun and easy.

Sometimes, silly small things about code I write just delight me. There are lots of ways to time things in R. 1 Tools like microbenchmark are great for profiling code, but what I do all the time is log how long database queries that are scheduled to run each night are taking. It is really easy to use calls to Sys.time and difftime when working interactively, but I didn’t want to pepper all of my code with the same log statements all over the place.

Non-standard evaluation is one of R’s best features, and also one of it’s most perplexing. Recently I have been making good use of wrapr::let to allow me to write reusable functions without a lot of assumptions about my data. For example, let’s say I always want to group_by schools when adding up dollars spent, but that sometimes my data calls what is conceptually a school schools, school, location, cost_center, Loc.

I have been fascinated with assertive programming in R since this from 2015 1. Tony Fischetti wrote a great blog post to announce assertr 2.0’s release on CRAN that really clarified the package’s design. UseRs often do crazy things that no sane developer in another language would do. Today I decided to build a way to check foreign key constraints in R to help me learn the assertr package.

Here’s a fun common task. I have a data set that has a bunch of codes like: Name Abbr Code Alabama AL 01 Alaska AK 02 Arizona AZ 04 Arkansas AR 05 California CA 06 Colorado CO 08 Connecticut CT 09 Delaware DE 10 All of your data is labeled with the code value.

One of my goals for 2017 is to contribute more to the R open source community. At the beginning of last year, I spent a little time helping to refactor rio. It was one of the more rewarding things I did in all of 2016. It wasn’t a ton of work, and I feel like I gained a lot of confidence in writing R packages and using S3 methods. I wrote code that R users download and use thousands of times a month.
