a fun thing to do for papers with good source code available is to git clone the paper repo, drop the paper pdf in, and then tell claude to, for example, write an interactive opengl visualization of Figure 4 (adding the plot from Figure 2 on top) with sliders for playing with the parameters

Magnetic Fields:
Find a central metaphor that's so good that everything aligns to it. Design meetings are no longer necessary, it designs itself. The metaphor should be crisp and fun.

Smalltalk is object-oriented, but it should have been message oriented.

Snobbery:
Turn up your nose at good ideas. You must work on great ideas, not good ones.

Appreciate mundanity: after all, a pencil is high technology

One goal: the computer disappears into the environment

The computer shouldn't act like it knows everything.

The whole notion of 'programming language' is wrong.

it's not just programming any more. Claude Opus 4.6 is a pocket mathematician. an unreliable one, but experts can get real results from these things, it seems.

That's a lot of proofs:

> In two weeks, Gauss then autoformalized the 24-dimensional case using only the original paper as input, performing autonomous literature searches when needed. This brought the total sphere packing formalization from 70k to ~200k lines.

Using Gauss, we have helped formally verify the sphere packing problem in dimensions 8 and 24 β€” certifying that the E8 lattice and the Leech lattice achieve the densest possible arrangements of non-overlapping spheres in their respective dimensions.

> In just 5 days, Gauss automatically proved all remaining results needed to verify the result in 8 dimensions. The Sphere Packing team estimated that the 8-dimensional case alone would have taken six more months of work with existing tools.

but then you have the problem of making some backend system that categorizes all the possible topics that people are posting about. this is at minimum LLM-complete, and doing this at bluesky scale seems to require a lot of infrastructure!

Your feed was then often things about the topics you followed, but somethings adjacent topics that the recommendation algorithm thinks you may also like. in this model, I suppose the idea would be to extract topics from a user's bluesky interactions and blog posts.

yeah I think "how do you register interest in topics in this system" is not fully worked out in my mind. On maven (I discovered it's still up, app.heymaven.com) every post has topics extracted automatically, and then each user had to follow individual topics, and you could see what everyone followed

Kenneth Stanley talks about this in www.youtube.com/watch?v=73sv..., the phrase "what is transformative to you cannot be decided through consensus" has been rattling around in my brain ever since (esp. as I browse For You, unfortunately). I wish atproto was more mature when he'd tried making this

Because of the scaling work, I became completely absorbed
with how the exponential increase in complexity of integrated
circuits would change the way that we think about computing.
The viewpoint of the computer industry at the time was an out-
growth of the industrial revolution; it was based on what was
then called β€œthe economy of scale.” The thinking went this way:
A 1000-horsepower engine costs only four times as much as a 100-
horsepower engine. Therefore, the cost per horsepower becomes
less as the engine is made larger. It is more cost effective to make
a few large power plants than to make many small ones. Effi-
ciency considerations favor the concentration of technology in a
few large installations. The same must be true of computing. One
company, IBM, was particularly successful following this strat-
egy. The β€œComputing Center” was the order of the dayβ€”a central
concentration of huge machines, with some bureaucrat β€œin charge”
and plenty of people around to protect the machines from anyone
who might want to use them. This model went well with the bu-
reaucratic mindset of the timeβ€”a mindset that has not totally
died out even today.
But as I looked at the physics of the emerging technology, it
didn’t work that way at all. The time required to move data is set
by the velocity of light and related electromagnetic considerations,
so it is far more effective to put whatever computing is required
where the data are located. **Efficiency considerations thus favor the
distribution of technology, rather than the concentration of tech-
nology.** The economics of information technology are the reverse
of those of mechanical technology.

just set up a tangled.org knot for fun. you can't yet migrate an existing repo to a new knot (tangled.org/tangled.org/...), but it's easy enough for me to re-create my repos since they currently don't have state outside of git

so the kanye seeddance video didn't give me me too much motion sickness, but this one does. it's the rapid camera pull back that does it. it's been years, seems like the labs are never going to fix this problem. looking forward to a glorious future of AI-generated ads that literally make me nauseous

yeah, the flip side of my post above is "i am not a computer scientist, so I will not be learning git, and AI will handle all of my version control tasks". there's two LLM modes: running straight through complexity walls that I don't care about, and delving into the gaping maw of complexity i do

09.02.2026 18:14 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

i think this is right. LLMs are great for overcoming incidental complexity, we just need to be careful to not to use it to avoid understanding essential complexity. it's way more important to understand eagain.net/articles/git... than it is to memorize git syntax (the CLI is not great!)

Reality has a surprising amount of detail

the main barrier to some of the transhumanist visions I'm seeing is that "reality has a surprising amount of detail" (johnsalvatier.org/blog/2017/re...), which must be delicately managed when you make physical things. the poor chatbots don't have high resolution interfaces to the world yet.

but what I'm seeing is reliable agentic coding requires sufficiently rich observations for tight feedback loops, which is much easier for pure software plays than for physical systems (there's a good reason why anthropic's recent team-of-claudes experiment wrote a programming language compiler).

it took me awhile to come around to this because i've been programming since i was 12, have only ever worked as a software developer, have an M.S. in C.S., etc., so I'm fairly invested.

It’s one thing when newcomers fall into this dopamine loop and produce something. When Peter first got me hooked on Claude, I did not sleep. I spent two months excessively prompting the thing and wasting tokens. I ended up building and building and creating a ton of tools I did not end up using much. β€œYou can just do things” was what was on my mind all the time but it took quite a bit longer to realize that just because you can, you might not want to. It became so easy to build something and in comparison it became much harder to actually use it or polish it. Quite a few of the tools I built I felt really great about, just to realize that I did not actually use them or they did not end up working as I thought they would.

it's been clarifying seeing writing like this because my reaction has been exactly the opposite: it seems like software is no longer the main bottleneck, so i've de-identified as a software developer and pivoted to learning more about hardware, which seems to me where the remaining bottlenecks are.
