Speed matters: Why working quickly is more important than it seems

from the jsomers.net blog [alt+shift+b] in programming

The obvious benefit to working quickly is that you'll finish more stuff per unit time. But there's more to it than that. If you work quickly, the cost of doing something new will seem lower in your mind. So you'll be inclined to do more. The converse is true, too. If every time you write […]

The paper computer

Now that we have actually good AI, I have this vision of a form of computing that doesn’t involve me using a computer so much. Imagine you had the day’s emails to go through. It would be nice if the ones that required a simple decision could be dispatched with a few pen-strokes: I could write down a date that would work for that meeting; check a box to accept that invitation; etc. If an email required me to review a draft, I'd love to mark up a print version on my couch, sans screen, and have those notes scanned and sent off as if I'd done the whole thing on Google Docs. The point is not to give up on virtuality, but just to save the end user from having to interact with it. It's great to be able to send information to anyone in the world instantly; but let me do it without the glaring screen and the thousand distractions. Is such a thing even possible? I'm not sure, but I just now uploaded a first draft of this post, handwritten in a small notebook, into ChatGPT. Its transcription was nearly perfect. A first draft of this blog post Here's another example: when I really want to play with re-arrangements of a complicated outline, or when I want to collaborate with someone else on one, I find myself laying physical note cards on a table. Having real objects to work with allows for more flexibility than software. If the problem demands it, you can stack cards, draw on them, cut them, tape things to them, etc.—and none of these improvised ways of organizing has to be coded up in advance. Space turns out to be a good way to organize information. I gather that in the paper days if you had a big project you were working on, say a book, it would spill out into the room you were working in: chapter outlines pinned up on the walls, stacks of books in meaningful piles on the floors, folders with drafts and clippings. Certain sections of the work in progress would become associated in your mind with certain parts of the room. Chapter 3 would be over there. I rarely use paper or physical space this way because it lacks critical conveniences. A huge wall-mounted paper calendar is maybe the best way to plan and visualize a large coordinated effort. (In "making-of" documentaries you find that movie shoots are often planned this way.) Everyone can see it and point to it because it's at human-scale; you can express many dimensions of information simultaneously using shape, color, position, size, and any other physical attribute. But I have a hard time understanding how I'd keep such a calendar up to date. In practice, like almost everyone else, I use a virtual calendar that automatically adds events as I'm invited to them, syncs with other people's calendars, reconciles time zones effortlessly, and interoperates with other programs like email. Could we get the best of both worlds? In other words, shouldn't one goal of rapid technical advancement be some melding of the physical and virtual worlds such that I can sit quietly in an easy chair with pen and pad; or lay cards out on a table to organize my thoughts; or turn a room into the embodiment of a project; and yet have the same flexibility, portability, persistence, and remixability as in the digital versions of these things? I spend a lot of my day on screens. There are many problems with these things, articulated well by Bret Victor in the context of his Dynamicland project. Screens are small, antisocial, and they have a tiny vocabulary of affordances compared to physical objects. Plus they have the problem that they make it difficult to just use your calendar, todo list, or map—or even just respond to a friend's message—without encountering something else along the way, like a social network, short-form video, Slack, the news, or some other notification. To state the obvious: your phone is the best place to keep your calendar and inbox and todo list because you always have it with you, but of course that makes it ripe for other intruders. Bundling makes your phone indispensable, but also a menace. If nothing else I'd like it if operating systems and web browsers helped me be less distracted and frenetic, instead of encouraging exactly that multi-tasking freneticism. When I opened my phone or computer, it'd be nice if it was constrained to operate in a mode purpose-built for whatever task I intended to use it for. If I want to look something up, for instance, my phone should be a look-up machine (ie no texts, no apps, no ads, just a place for my question and the answer). If I want to compose a word of the day entry, I should launch straight into a browser with the tabs I regularly use for that, including the CRM, Webster's dictionary, and the OED; if I want to work on an article, my computer should assume the form of a typewriter, word processor, or McPhee mode note-processor depending on what stage I'm at. In each of these modes everything else should disappear, inaccessible. At least then you could mimic in software that thing you get from physical objects—which is that they are usually built to do one, and only one, thing well. My alarm clock, for instance, is just an alarm clock; and that's what I like about it! Not too long ago I spoke to a roboticist for an article I was writing, who worked with large autonomous earth-moving machines—e.g. a retrofitted excavator that could lift a boulder, scan its every edge and dimple, then model how it would settle amongst other boulders in a retaining wall before placing it there. He imagined a future in which such machines enabled a return to natural materials in the built world. He talked about old stone walls he’d seen in New England. Those walls, made of loose rocks found in situ, are lovely and sturdy, and adaptive—constantly rebuilt as farmers go about their work and notice areas that need patching up, adding stones they find lying around. But this is the very reason such walls aren't really built anymore. They're too labor-intensive. We live in a prefab world because the scarce thing now is not material or money but "the works and days of hands." I am moved by the idea that our future could feel less futuristic than pastoral. High tech could save us from high tech. We'd go back to the old interfaces without giving up the conveniences of the new ones. Read, write, communicate, create—and hardly ever see or touch a screen. I'm not sure that'll happen or be what people want. But shouldn't we be thinking of ways to use the new magic to spend less time tapping and clicking?

The McPhee method

When I first started writing professionally, for the Atlantic’s website, I taught myself “reporting” with a simple self-made curriculum unfolding over six or seven articles. The first two pieces I wrote from my head, with reference to things I already knew or to books I’d read. For the third, I layered in firsthand experience, when […]

Should we cool it with the historical present?

On podcasts it's pretty common to hear something like this: So Alexander Hamilton has just finished law school, and he's trying to make a name for himself. He's only been in New York a few years. So he takes on this case... The problem with the past tense ("Hamilton had just finished law school, and […]

Introducing Five’Em, a Texas Hold’Em variant

The game of Five'Em was invented by two friends of mine, Ben Gross and Rich Berger, to combat Hold'Em fatigue. The rules are simple: You're dealt five hole cards instead of two, and after each round of community cards comes out (starting with the flop), you discard one of these extras. After the river is […]

The three-page paper that shook philosophy: Gettiers in software engineering

In 1963, the philosopher Edmund Gettier published a three-page paper in the journal Analysis that quickly became a classic in the field. Epistemologists going back to the Greeks had debated what it meant to know something, and in the Enlightenment, a definition was settled upon: to know something is to have a justified true belief […]

Tyding up my side projects

Being focused is about doing less things, and giving more space to the stuff that matters. I am spread out on too many projects and I can’t give enough attention to all of them. It’s time to clearly sort out which one I will keep maintaining and which I should drop entirely. Chuttersnap Mikochi Mikochi is a self-hostable remote file manager I’ve started in 2023. It’s my most successful open source project. I personally use it every day, and thousands of people have adopted it and started using it on their own servers. This year the project has been receiving more and more attention. Maybe it just reached a critical mass of users. In practice, that means a bit more maintenance work, since people have been pointing out bugs and suggesting new features. At the same time, working on Mikochi is fairly enjoyable. It’s a small, self-contained project made with technologies I enjoy working with. I’ve got no complaints about spending some time working on it. Verdict: Keep maintaining Mikochi and actively continue improving it. Itako Itako is an investment portfolio tracking SaaS. I built it for the most part between 2023 and 2025. In terms of scope, it’s the largest project I’ve done entirely by myself. Is it a success? Not really. There are definitely a lot of people who tried Itako, and some who’ve kept using it a bit. But it’s not engaging enough for anyone to consider getting the premium plan. And honestly I don’t find myself using it that much. My view of investing and portfolio management has significantly shifted since I started this project. While I used to think that more sophisticated analysis would lead to better returns, I now realize that the only strategies that consistently make money are honestly stupidly simple. Or maybe it’s a U curve: on one end you’ve got a monkey throwing darts, on the other end you’ve got Jane Street, and everyone in-between fails to beat the market. Anyway, the biggest issue with Itako is how dull working on it is. The interesting parts of the projects are working on statistics and data visualization. But in practice, 90% of the time is spent tediously fixing data, understanding why some German stocks have an exchange labelled XETRA instead of XETR, why some Belgian stocks still have quotes while Euronext shows them as delisted… Verdict: Shut down Itako today. Milou Milou is static site generator for press kits. It started as a fork of presskit.html which was completely abandoned at the time. It’s a very useful tool. At Tsukumogami, it’s part of our Cloudflare pipeline which builds our website in a few minutes whenever we need to change something. It seems like a few other game studios have picked it up, although I rarely get any feedback about it. I’ve not spent too much time working on it in 2026. I think it could be interesting to come back to it and add a feature or two. Better support for multiple languages could be an idea. At least, I need to make sure we don’t fall into the good old Node.js dependency rot. Verdict: Spend some time on Milou. Luluka Earlier this year, I created Luluka. It’s a CLI that allows previewing the output of Ebitengine shaders. I do still think Ebitengine is a great engine and Go is better suited for game development than most people realize. However, after quite a long period of experimentation around it, we’ve decided to remain a Godot studio. On top of having quite a large sunk cost in infrastructure surrounding Godot, the tooling and possibility of doing 3D games still makes it a more attractive engine for our use cases. And I’ve been doing a lot of 3D work lately, so better put those hours to use. Verdict: Archive the project. The rest I’ve had a lot of good ideas that stayed as almost empty repositories in my GitHub. For example, Hakumei was a terminal companion to Mikochi. I made a few commits on this project and never found the time to work on it again. I have to admit I’m probably never going to have the time to work on all those repositories. Time to archive them all!

Not everybody is an AI expert - and that’s fine

This post was previously published through my newsletter on November 9, 2026. From time to time, I will republish newsletter issues on my blog here if I think people (and search engines) might benefit from it. If you want to read everything I’ve written once it is posted, I recommend signing up for the newsletter. If you’re doing anything to stay on top of what is happening in the world of software testing and test automation, like browsing or even posting on LinkedIn, which I stopped doing for the foreseeable future, or reading blog posts - my preferred way of keeping up these days, and I highly recommend Dawid Dylowicz’s excellent Software Testing Weekly aggregator mailing list if you prefer longer-form reading, too you’d be thinking that AI has consumed our entire field, and that everybody (or at least those who post or write in public) is an AI expert these days. The reality, though, is far from that. Yes, some people use a lot of AI, even when I would only call a small fraction of them ‘experts’. I definitely do not classify myself as an ‘AI expert’, by the way. A much larger group uses AI on a less frequent basis, and they’re getting some value out of it. Sometimes more, sometimes less. That’s the group I’m probably in. And then there’s a group of people who haven’t really been using a lot of AI at all so far, beyond maybe the odd prompt to ChatGPT or Claude. I don’t have the actual numbers, but I suspect that this group is a lot larger than you would think from browsing your feed or surfing the blogosphere. You just don’t see them, because they’re typically not the people who do a lot of work in public. A few weeks ago, I started working with a small group of testers to teach them how to use AI in their daily work. This work covers both test automation as well as broader software testing tasks, as some of them contribute to automation on a daily basis, but not all of them do. I’m working with them one day per week, on average, for three months, and we’re making small steps towards making AI a more prominent tool in their tool belt. So, what are we working on right now? I’m pulling ideas from my ‘Valuable Feedback, Fast with AI’ course, and so far, we’ve spent some time setting up Claude, going over some important concepts such as context windows, models, tokens, and (of course!) the probabilistic nature of LLMs, and what that means for the results they provide. We have gone through several initial conversations, using Claude to learn more about and review specific user stories, which was an excellent segue into using talking about MCPs and setting up a connection to both Jira and Confluence using the Atlassian MCP. Last week, we also started experimenting with writing straightforward skills to make it easier for Claude to repeat certain actions in a structured way. These actions ranged from reviewing stories and acceptance criteria to refactoring small chunks of code in their (Robot Framework-based) test automation suite. What I loved about this is the avalanche of ideas that popped up in their heads when they saw how easy it was to use Claude. We made a short to-do list of ideas to try out for the next couple of weeks, and I’m looking forward to seeing them getting more confident around using Claude. One thing I have noticed is that their level of comfort around using AI varies quite a bit. Some of them are naturally quite cautious, which means they’ll ask ‘can we really do this?’ and ‘should we really do this?’ frequently before even submitting a single prompt. This is a good habit, I think, but we’ll have to do some work to get them more comfortable with using LLMs, without losing too much of that caution. Others in the group are the opposite: I need to hold them back a little, because otherwise they’ll create a beautiful mess within days, simply because they see so many opportunities to use Claude in their work. That, too, isn’t inherently bad, but I do want to teach them not just how to get the most out of an LLM, but also (more so) how to use AI prudently. Over the next couple of months, we’ll dive deeper into writing better prompts, creating and structuring skills, better context management, and creating and using agents, and probably a few more things, too. I’m looking forward to seeing these people grow more comfortable around using AI in their daily work, and figuring out where AI genuinely adds value and where it doesn’t in their own context. Is there a deeper message in this newsletter? Maybe not, and I’m just happy to tell you about this project, and how it is a great example of a what I call ‘corporate mentoring’, a very efficient way of teaching a small group of engineers new skills, within their own context. But maybe it’s also to show you that, despite what you might see on the Internet, especially those places featuring a lot of self-congratulation (I’m looking at you, LinkedIn), not everybody out there is an AI expert. At least not yet. So, if you feel like you’re ‘behind’ simply because you’re not running at least 17 agents continuously, creating 5400 merge requests per day, know that you’re not alone. Quite far from it, I would say.
