A lot has been said about DHH, but, I think the moment where you can see that the guy has _clearly_ lost it is this quote:
> It is impossibly fast. And you know what? The binary? Half a megabyte. Half a fucking megabyte. I— you could fit that on a floppy disk almost. With a little compression. This is the other payoff.
The guy now(?) thinks like a lossy abstraction that speaks in tropes.
He has become the LLM - I would say, if I didn't know that even a 9B one can tell me with absolutely certainty how much space there is on a fucking floppy.
There is no reason to get into all the politics stuff when this is where the guy is at. Basic fact retrieval.
(Pedantically, one could now argue that it was not clear which floppy format the guy was referring to. And yes, that would be true, but by thinking that thought, you have thought about the sentence more than its author has.)
If we are talking about the standard 3.5-inch High Density (HD) floppy disk, which is the universal cultural icon for "floppy disk" (and the save icon in your software), the capacity is exactly:
1,474,560 bytes
This is equal to 1,440 KB (using 1024-byte kilobytes).
It is marketed and universally referred to as 1.44 MB.
Now, let's run the exact math on DHH's keynote claim:
If you put his "impossibly fast" 0.5 MB binary onto a standard floppy disk, you would have nearly a full megabyte of free space left over. You could fit almost three of his binaries on a single disk. You do not need "a little compression." You need a basic understanding of less-than/greater-than operators.
The Preemptive "Reply-Guy" Shield
Now, just in case a Hacker News pedant is reading this and wants to argue that DHH was talking about a different format, here is the absolute certainty on the rest of the historical hardware:
3.5-inch Double Density (DD) (1980s): 720 KB. (A 0.5 MB file still fits easily without compression).
3.5-inch Extended Density (ED) (1987): 2.88 MB. (Fits five of his binaries).
5.25-inch High Density (1984): 1.2 MB. (Fits two of his binaries).
5.25-inch Double Density (1981): 360 KB.
8-inch Original IBM (1971): 80 KB.
To make DHH's statement mathematically correct, we have to pretend he was standing on a stage in 2024, hyping up modern web framework binaries, while indexing his storage metaphors to a 5.25-inch Double Density disk from 1981.

Thank you, Gemini. Much appreciated.
Also, I love the tone.
(You can tell that it is actually that LLM by it thinking that it is still 2024)

I'm missing something (as usual) because I don't see what's wrong with his statement.
