The sixth die this week had a particle of dust on it that I can still see with the 40x. I know which stage of the process it came from. I know the fan, I know the filter, I know the hour. I built the positive-pressure cabinet out of plywood and acrylic because a used one was more than I could justify spending on a thing I didn’t need to make. I don’t need to make RAM. I already have RAM. The chip on the bench next to me cost three dollars and works. Mine does not work yet. When it does, it will hold perhaps a few bits, badly, for a few minutes. I will know exactly which atoms are holding the charge. My grandmother could have understood, at a general level, everything I am doing. I don’t think there’s another technology in my house about which that is true.

The bug was from 1991. The mov instruction that set ES to equal DS had been wrong for thirty-four years, which means it had been wrong since before I could read. The person who wrote it meant to copy a MAC address into a buffer, and they copied it into the compiler’s null-pointer detection region instead, because they confused two segment registers in a way that is easy to do in small memory models where, most of the time, ES and DS are the same. Most of the time is not all of the time. The program crashed when it wasn’t the same, and for thirty-four years nobody was running the program in a situation where it wasn’t. Then I was. I spent three evenings reading assembly written by someone I have never met, who may have retired, who may no longer be alive. The bug was a letter. I wrote a letter back, in the form of a four-line patch. I put my name on it. I put the date.

I have a colleague running a Minecraft server on a UNIVAC 1219B. Ninety kilobytes of RAM, a quarter of a megahertz. He wrote a RISC-V emulator in UNIVAC assembly and then compiled the server into RISC-V and then ran the emulator on the machine and then waited. The thing runs. Eight players can join. He knows the exact number of cycles every packet consumes on the way in and the exact number on the way out. I think about him often when I am grinding a die under the microscope. We are doing the same thing. He knows each cycle the way I know each particle. There is a laptop on my other workbench with a haptic touchpad and a chassis you can open with a single tool, and a little QR code on every component that tells you how to swap it. Someone is very pleased about having designed that touchpad. They should be.

Today we are announcing the next generation of our image platform, which is smarter, sharper, and still evolving. The model has been trained on a wide range of internet-available materials and is now capable of producing photorealistic scenes of places and people that do not exist. In parallel, we are pleased to share that an agreement has been reached to bring together two leaders in agentic development, unlocking significant synergies for the enterprise segment. To ensure the highest quality of training data for our next-generation foundation models, keystroke and mouse-movement capture will be enabled across internal workstations beginning next quarter; the data collected will not be used for performance assessment. For clarity, we are running a small test on approximately two percent of new prosumer signups; existing subscribers are not affected. We remain committed to the trust our users place in us.

Because I am writing this entry I am, for the moment, responsible for everything in it. If I am wrong about the bronze-working of the ancient Etruscans, Mr. Galton, who reads these pages in proof, will write to me and I shall be ashamed. It is a discipline of a sort. I have today been reading the entry for BOILING, which, in an earlier proof, I saw treated only the medieval English punishment, in which persons convicted of poisoning were immersed in cauldrons and cooked; the physical process of heating water until it changes state is, it seems, too familiar to be described. My colleague who wrote it knew this was an odd choice and made it anyway. I have asked him to reconsider. Should he decline, his initials will stand at the bottom of the entry and mine will not. A reader a hundred years hence will know whom to blame. One notes, in passing, that games and puzzles composed by a single hand are found, across the centuries, to be the ones players remember; this is not mysterious. There is something in the fact of one person having chosen a thing, and having been findable afterwards for the choosing of it.

On the bench, under the microscope, a second die. No dust this time. A thin scratch at the edge where the tweezers slipped, which means I did that, yesterday, at about four in the afternoon. I have annotated the plate in pencil. I am going to try again.
