I (and I'm sure many others) have been thinking about this a lot over the last couple of months. I called it "Extremely Personal Software" in a blog post a few months ago (https://redfloatplane.lol/blog/14-releasing-software-now/) but there are lots of names and concepts floating about for the same basic idea.
I think it's possible the amount of new software that will be written for an audience of 1-10 will be greater in 2026 than in any previous year, and then the same again for many years to come. I also think a lot of this software will be essentially 'hidden' - people just writing this stuff for themselves because the cost to say things to an agent is very low compared with the cost of actually planning out a software design and so forth.
Interoperability will probably be important in the next few years and I wonder if this is something solvable at the agent/LLM level (standing instructions like 'typically, use sqlite, use plaintext, use open standards' or whatever). I also think observability and ops will be pretty important - many people who want personal software but don't care for the maintenance and upkeep.
I find this fascinating. I also like to customize my desktop experience with my own code, but it's more assembling stuff with some additional code as glue.
A word of warning: a reliable lock tool for X11 is difficult. You should look at XSecureLock, which uses a multiprocess approach to avoid leaving the desktop unprotected in case of crash. It also implements a number of countermeasure to ensure the desktop stays locked and the locker stays in the front of the display. It's small too, so easy to audit (but written in C).
This is very cool. I wonder how much time did it actually take, and how much did it cost, because Clause Code is very much not free [1] [2]. It's more like hiring a robotic contractor, very fast, but with a serious hourly rate.
I'm on Claude Max, so it didn't cost me anything more than the subscription I already have. Had to use it for Something. As for time - for the full CHasm and Fe2O3 suite of sw, I started the work 2026-03-29 and have probably spent 60h or so of my time. But then again I have a very tailored CC setup that I have fine-tuned since last summer with more than 70 CC projects helping me get it the way I need it to be since then.
So, it's at most $400 in Claude expenses for a fully custom suite of software in 2 months. Even if your time is 300/h, it's less than $2k in your own time (which, I would expect, you enjoyed spending). That's insanely impressive.
I need Claude Max in any case for my work, so the cost is effectively null. And I do creative stuff in my spare time regardless, and I don't really think about my hourly rate when I play with my kids either ;)
Sorry I have a question that is a little off-topic: what's the value of generating an image of a laptop on a desk? That's not like it's particularly relevant, when you could have integrated a screen shot of your set-up (like the same one you put on a few of your repos) or something more unique, and even if you want to show that, it's easy to find similar images with the same vibe, so I guess it's for some fun I missed in the process?
On this software itself: I’d like to know how this feels to use. It’s so very lightweight. Does it feel categorically different to what we are used to?
One of the things I miss about the 1980s home computers is that they booted into a usable command line in a handful of seconds, from a few KB in ROM. Imagine what today’s HW could do if we’d retained that level of efficiency.
Same reason people muck about with knowledge management systems... to put off the day when you have to sit down at your desk and actually do something.
seriously.... we already have a constellation of good deterministic tooling for taking a relatively high concept spec to low level assembly. what does an llm offer in generating optimized asm that rust wouldn't??
Less memory footprint. No reliance on libs. Pure first-person control. No wasted CPU cycles is the target here for me. And if you read the post, the asm set is only for the desktop itself. The tools I use are in Rust. Result is: Laptop now runs at between 5-6W (down from ~9W) [XPS14 latest hw] on Ubuntu 26.04 - giving me around 3.5h extra battery life.
rust can do that. You can run a hyper stripped down rust that was made for embedded devices specifically because those devices don't have room for a runtime.
OP did this:
Prompted CC for all the points I wanted included (something like a 200 word prompt) and asked CC to draft it, including all the links added to the table I furnished. Then I edited the draft (about 50% then edited). Then asked CC to spellcheck and fixed the 5 it found.

A really good and thoughtful response. Thanks.

I’m inspired by the message.

we are there now. depending on boot loader/os combination, one can get to the sub 1-5 sec range, if its cli-only.
It feels very different. It's all damn instant. Me happy.
Some screenies and the code at 0…
I struggle to understand why, though.

Why did you choose to have Claude write it in assembly language?
There are big benefits to using a language that has good static analysis with LLMs.

I'm sure I can. The original challenge was more in line of "I wonder if CC can do this now?"
And it apparently can. And very well.
One advantage seems to be that the complete asm file fits easily into CC context window.
Did OP write this by hand? It reads like language written by a human overfitted on GPT 4o or Claude.
OP did this: Prompted CC for all the points I wanted included (something like a 200 word prompt) and asked CC to draft it, including all the links added to the table I furnished. Then I edited the draft (about 50% then edited). Then asked CC to spellcheck and fixed the 5 it found.
If they basically generated a desktop for themselves, what’s the chance they didn’t generate the article? I think pretty slim.
Also, reading it is probably not the intended use. It’s probably: “Hey Claude, give me a TLDR of this”
Who cares? It’s their content. If they hired an editor to help them, cool. If the content doesn’t suit you, move on.
But the incessant “AI was used here, thus is it garbage” is long past time to enter the grave.
