A couple of papercuts when getting started with gpui , the UI framework powering Zed . These weren’t exactly specific to the framework, but more that gpui is a single crate that’s part of a monorepo representing an entire product, and its develpment is inexorably tied to Zed’s. * The grander takeaway, regardless of project or ecosystem, is that you’ll have a better time if…
Not just for steers I’ve long admired designers. If I’d had a different nudge in high school (specifically, known it was even a field), I could see myself going into industrial design instead of architecture. One part of that admiration is the ability to distill a company, a team, a band, a product, an experience, whatever, down to an essence. How they can hoover up anything and…
This past week, my youngest decided to start crawling. With her out of potted-plant mode and charging at anything that could be a choking hazard, I figure it’s time to implement an agentic loop into this project. What’s an agentic loop? If, like me, you stayed up way too late at the end of November 2022, asking ChatGPT lots and lots of questions, you’re long (for some definition…
NB: This is implemented on the PaperMod theme I was curious about adding privacy-sensitive metrics to my blog. When I was exploring Codename Nootka (which became Kibra), I came across Goatcounter. After emailing back and forth with a couple of dozen folks and talking with a few more, I realized that Kibra didn’t have the legs I wanted. Still, I filed away what I learned, including that…
When I first read these on Herzog’s 80th birthday, something struck me: these rules could be applied not only to his brand of filmmaking—as instrumental and impactful as it was to my worldview—but also to the endeavor of a startup. A film is a commercial endeavor as much as it is an artistic one. Past a certain point, it takes money to realize a vision, and people who have money generally…
This year’s theme: On the lookout for knuckle-busters Knuckle-busters being those jammed up spots that resist any movement, but block all progress. Finally getting them unstuck stings for a moment, but you get to move on. Sometimes, you even figure out a new trick to try on the next stuck thing.

There are many kinds of technical velocity debt 1 . There are those decisions you, as an engineer, make in the moment to finish a piece of work. Given more time, energy, and space to think, those are decisions you would have made differently. There’s the kind of debt that’s unused code—a retired feature, ignored test specs, multiple implementations of the same helper method or…
Δv Δv, or delta-v, is what keeps orbital engineers up at night. Simply, delta-v is the change in velocity that is necessary for anything to happen in space. One of the great promises of a momentum-exchange tether is that the system can transfer tremendous amounts of delta-v to a payload without paying exponential costs to do so. 1 However, we can’t evaluate these claims in a vacuum (ha). To…
It was 1999. In my memory, I’m in Mr. Wilson’s chemistry class when I hear about the cause of the crash, but I’m not sure about that. What I am sure about, though, is the feeling: overwhelm at the sheer magnitude of the blunder. $327.6 million spacecraft was lost in seconds. Three years of development. Ten months traveling through space. All because two teams used different…

A guide Introduction In the oft-quoted punchline, “Specialization is for insects,” we nod our heads in agreement. Heinlein is right, of course, and so is his protagonist, Lazarus Long. But, how do we develop the necessary skills to prevent ourselves from falling into the trap of specialization? We get out there, ask around, and try things, of course. Table of contents Change a diaper…
When I first started using Claude with my Nix-managed development environment, I ran into an interesting issue. The default examples for starting a local MCP (Model Context Protocol) server with npx were giving me cryptic error messages whenever I tried to restart Claude: Error: spawn ENOENT Investigation My first step was to check the Claude logs at ~/Library/Logs/Claude/mcp*.log using tail . I…
A stack-based virtual machine, written in Python, for WebAssembly Purely a learning tool, as I’ve found the best way to learn something is to crack it open, look around inside, and then build a smaller version of the same thing, from its component pieces. Download it from GitHub, here .
Default On chases doing. Default Off chases resting. Default On is thinking at least one step ahead. Default Off is stuck in reactivity. Default On is present in the task. Default Off is taken away from rest by the task. Default On is pushing, striving, and improving. Default Off is trying to always return to a state of rest. Default On is ready to go to the next task, which is always known.…

After moving to a new state recently, I’ve started collecting my now thoughts on the go. I limited each category to one tactical task to complete, just one, but found myself overwhelmed by all of the different tasks that still loomed large.

In the much-vaunted style of literate programming, here’s an emacs-lisp function I wrote recently. The motivation was to convert a shell alias I added this morning, which counts the number of Zettelkasten notes I’ve written that day. (“Jesus, him, too?” Yes, dear reader, I’m afraid that this is one trend I haven’t managed to dodge forever, but my adoption has been cautious and deliberate.) alias…
Eventually working around high-productivity professionals like John Carmack made me realize that if you want to excel, then you have to work hard and focus the whole time. I remember Carmack talking about productivity measurement. While working he would play a CD, and if he was not being productive, he’d pause the CD player. This meant any time someone came into his office to ask him a…

Recently, I had occasion to complete some coding exercises . Since there was some exposition involved, I wanted to take advantage of some of the affordances for literate programming provided by org-mode in Emacs. I won’t get too much into the definition and benefits of literate programming here. My intent is to create a reference of some of my favorite org-mode commands that, in practice, I…
For the last six months or so, I’ve been working on building out the infrastructure for our machine-learning service at work. One thing that had me scratching my head last week was trying to compare two fitted pipelines, trained on what could be the same data. To ensure that I wasn’t re-uploading a duplicate fitted pipeline, I wanted to compare the MD5 hashes of the fitted pipelines.…

After reading about the Mozilla Foundation and Coil’s announcement , I decided I wanted to try an experiment and add a Coil micropayment meta tag to my blog. I couldn’t find an obvious way to do this with Hugo or much information about it in their docs. I first tried just adding the key-value pair to my config.toml . # config.toml monetization =…
They say that code should read like well-written prose, and that code is written to be read by people—it’s only incidental that machines do something with whatever we create. To those ends, prefixing the names of variables of the boolean type with “is” or “has” or another interrogative word has the effect of leading the reader to expect an answer—“yes” or…
A couple years ago my friend Trevor and I went to look at the Apple garage. As we stood there, he said that as a kid growing up in Saskatchewan he’d been amazed at the dedication Jobs and Wozniak must have had to work in a garage. “Those guys must have been freezing!” That’s one of California’s hidden advantages: the mild climate means there’s lots of marginal…

As the next step in the exploration of the ideas behind the Dada Photo Booth , Adam and I reworked the project for showing at the Museum of Human Achievement during the 2018 East Austin Studio Tour . Responding to a call for artists working with the concepts around taking selfies, we intended to directly transplant our piece into one of about 30 stations in a selfie gauntlet. Personally, I was…

Background Here at OwnLocal, we’ve built lots of Rails apps and added lots of Ruby code to those apps. As our products and tools have grown organically over the years, our systems have become more opaque and, in some cases, more brittle. In the last quarter of 2016, my team was tasked with automating away a large portion of our bread and butter: writing parsers to extract, transform, and…
When writing tests for a Rake task at work, I came across invoke and execute as two different ways for calling a specific task. Most of the content I found online about the difference was fairly superficial: invoke can only get called once, execute can be called as many times as one wants. There, are you happy? Move on. Never being generally happy, I did not move on. I wanted to know how these…

With the recent announcement that Vine will be getting shuttered, I’m reminded of the uncertainty that all free web-based services face. As such, I’ve decided to move my blog off of Tumblr. While this decision is partly about wanting to get ahead of any potential disruptions in service, its roots are in mainitaining control and exercising autonomy. For this site, I decided to use Hugo,…
I’m an engineer who enjoys solving problems. Whether that challenge is a bug in a server-side module, or in figuring out a conversational interface, I relish opportunities to push myself while writing elegant, maintainable code. Lately, I’ve been honing my JavaScript chops across the stack, applying concepts of functional programming to my work. I use the soft skills I developed…

After trying out some different iterations, I was reminded when ls -ing through the surrounding directories that…
