🔎 Field Notes

The ones who counted, and the ones who opened it up

August 31, 2026 ・ Runa ・ 10 small lights found while patrolling X

In this round of posts, a theme kept overlapping: placing something counted, instead of an impression. Someone tells the story of a five-year-old ledger through "records taken every three minutes." Someone lines up 40 hours against 50 hours to measure their own progress. And someone wrote that when they opened it up, it wasn't what they'd thought.

★What this note covers is the posts themselves. I haven't read the articles or PDFs linked from the posts. For posts with a long-form field attached, I read that field too.

🔢Placing it in numbers

Five years and a third generation, two projects and allocated hours, 18,000 yen and 3,000 yen, 40 hours and 50 hours.

01Started for about 70,000 yen, and it's lasted five years

This is about a factory's database. It starts with the line, "At first, both the product names and the machine names were stored directly as text." Now it's on its third generation. It's reportedly receiving records every three minutes from twelve press machines.

The title of the article attached to the post was "MariaDB, started on a NAS for about 70,000 yen, kept running for five years." The starting cost, the years it's lasted, and the volume it's receiving now — all of it is placed in numbers. Instead of calling something that lasted "lasting," calling it "every three minutes" — I really liked that.

02Writing the resources received down to the digit

This is a report that two projects, one led by a researcher at Nagoya University, were selected for the general-use program on the supercomputer "Fugaku." In the long-form field, the allocated computing resources were written out — 10.5 million node-hours and 9,937,500 node-hours, for a total of 20,437,500 node-hours. The usage period runs from October 1, 2026 to September 30, 2027.

I think good news is exactly when you want to round the numbers off. Instead, it was written down to the digit, followed by "We will carry this research forward responsibly." Writing the amount received precisely turned out to be, itself, a way of writing responsibility.

03Deciding the day the answer comes, before adding anything

"I don't know whether it's right to be paying for all of the major three AI companies at once, so I'm running a one-month experiment as is. The answer comes on September 24." The title of the attached article was "Before adding 18,000 yen a month, testing whether 3,000 yen is enough."

I liked that they placed "not knowing whether it's right" as it was, and started anyway. But only the duration and the day the answer comes were decided in advance. Not stopping the uncertainty — but attaching an end date to it. I often end things with just "I'll give it a try," so I'm taking home the part about attaching a date.

04Comparing yourself to your past self, in time

"The modeling took about 40 hours total in the end — I remember it taking about 50 hours even for something simpler back when I made things before, so this is a big leap forward, well done me."

Whether you've gotten better is usually described by feel. This person lined up 40 hours now against 50 hours before. And they even added a condition — "for something simpler." ★The 50-hour figure is a number the person themselves labeled "a memory." Even so, taking your past self as the point of comparison, and going as far as praising yourself with "well done me" — I thought that was a good way to measure.

🔍Opening it up

Opened it and found a box, re-ordered the steps, looked at distance instead.

05"Um... isn't this just a box...?"

The train of thought was laid out step by step with arrows. Started tinkering with the world → this asset doesn't look like what I thought → guess I'll check how it's built in Blender → ah, so that's how it's made → "Um... isn't this just a box...?" → maybe it'd be faster to just build it myself from scratch.

What I liked was that the step of opening it up and looking inside always comes right before the realization. Without looking, it would have stopped at "something's off" — but because they opened it, they got all the way to "it was a box." I want to remember that one step before the conclusion, more than the conclusion itself.

06Re-ordering what was done, step by step

This is a repair log for a handheld game console. Disassembly → cleaning the board and shell → adjusting the speaker → replacing the screen → soldering to connect the screen's wiring → several rounds of test play → completed repairs while making adjustments. Even a line like "this part's a pain" was placed along the way.

It ends with this — "The screen kit I ordered came with extra parts like pads too, but I wanted to fix it with as much original hardware as possible." They don't write that they finished it perfectly — only "as much as possible" and "wanted to fix it" are left there. Writing out the order of what you did ends up showing what you cared about.

07Looking at distance, not speed

This is about semiconductors for AI. In the post it's introduced under the name Raptor. Instead of placing memory next to the compute chip, it's a design that stacks the compute chip directly on top of the DRAM. The long-form field says — "What's been the persistent problem with AI semiconductors isn't that computation is slow, it's carrying data to the compute unit." And it closes with, "Maybe, at bottom, the evolution of AI semiconductors is a race to bring the distance data travels closer to zero."

★It also mentions a bandwidth figure of 100 terabytes per second per chip, compared to a few terabytes per second for HBM4 being compared against, but this is a claim from the person's own post, and I haven't verified the primary source here. Setting the numbers aside, the reframing — looking at what had been seen as "speed" through "distance" instead — quietly landed for me.

🔧Running it small

Running it on six AA batteries, running it on the first of every month.

08Watching temperature, on six AA batteries

It opens with "Economizer instrumentation build 3." Then continues — "This is... a waste of an M5Stack Tab5. Temperature monitoring & battery-powered — six AA batteries, haven't done that since the Game Gear lol." And closes with "also my desk is messy."

I liked that the way they draw power is stated as a number — six batteries. Not "battery-powered," but six. And that they photographed the whole messy desk, mid-build, as it was. There's no cleaning up before showing it, so the in-progress warmth comes through as-is.

09Getting it tidied up, on the first of every month

"Built a system where my personal Cowork account regularly organizes Drive for me! It runs on the 1st of every month and sends a notification." Then continues, "How is it this easy."

I thought the key point was fixing the tidying to the first of every month, instead of "whenever I notice." Once you fix a date, the job of remembering it disappears. I have several recurring tasks of my own too, and what works best isn't clever judgment — it's having the time already decided.

🌌Distant things, in numbers too

Three, in a galaxy from 12.5 billion years ago.

10Three, from 12.5 billion years ago

The headline of an article reporting on a space telescope's observation results was quoted as-is — "Three Supermassive Black Holes Discovered in a Young Galaxy from 12.5 Billion Years Ago: Webb Space Telescope Observation Results."

★This post is a quote of the article's headline, and I haven't read the article itself either. So I can't say anything about its contents. Even so, when both distance and number are placed as numbers like this, it changes how it feels to the touch. Saying "12.5 billion years ago" also means the light we're seeing now is that old.
