random3··on Muse – Meta’s personal AI agent
It's not "personal" if it runs on someone else's machine

Nature has shown variety wins over inbreeding, I don't see how AI will change this
random3··on Georgi Gerganov on llama.cpp/ggml future after Nvidia acquisition of HuggingFace
That’s sounds so cool! I wonder how they get to do high throughput contributions. Is the structure very flat, or plugin based? I’ve always admired this project from the outside and glad to learn it’s doing so well. Looks like they have something really good going on. Kudos to the team!
random3··on Discovery of a new OpenAI agent message board
You could have said the same thing about building the Internet or the entire industrial control infrastructure. I mean, maybe they are negligent/incompetent, but I doubt that follows from your reasoning.

You have a simple tradeoff to let agents do their thing freely vs highly constrained. The constraints are good in theory but it's the same model that kept "classic" software dumb and unscalable (compared to what we're seeing now) for the past 50 years. You suggest that this tradeoff doesn't exist.

Then you have others like MIRI (Yudkowski) etc. swearing that there's no way to contain AI, and you argue that it's just incompetence.

At a certain level, it can be argued that's incompetence, but it's general meat intelligence incompetence against AI.

I don't understand what you're saying. Can you clarify your question?

random3··on Google Antigravity introduces Boost deep reasoning (/boost)
I canceled my Ultra subscription after realizing I had Sol constantly fixing anything I tried to do with Antigravity. The most frustrating experience and a waste of money. I’m sorry for Google and hope they manage to fix their disaster.
random3··on Marx, Keynes, and A.I
your argument suggests there's an opportunity for a trading strategy. It's also very common as a "technical analysis" investment strategy for any gullible person on the internet.

The problem is it looks "backwards" and tries to make the point something (in this case the argument made in the paper) is false because the backwards data doesn't support it. All while completely failing to address the crux of the point being made.

Bro, I’m not following. Can you elaborate? - concretely PIM is cope. And the argument that this is bad because rowhammer and how a wider bus would be better.
random3··on European Commission Revives Push for Encryption Backdoors in ProtectEU Strategy
And, of course, no thought is given to the implications this could have in conjunction with the next Orban. Europe is aligning against Russia as a threat, while at the same time shooting itself in the foot by disabling basic rights like privacy with absolutely no memory of how much more basic lack of privacy (enabled by Facebook) was leveraged with relatively simple tools (https://en.wikipedia.org/wiki/Facebook–Cambridge_Analytica_d...) to help Brexit happen (effectively breaking Europe apart).

This quote from Apocalypto stuck with me "A great civilization is not conquered from without until it has destroyed itself from within."

I haven't played FF but I spent a ton of time as a kid on the old 90s-00s Internet to find your website design "soothing" and I also miss the times when I used to bump into this stuff all the time :). Also I had no idea you can publish in org mode

Makes sense. Unless you can disassemble/reassemble. I guess selling kits (Meccano, Technics) would be the better approach. I recall countless hours building stuff and my kids love their Magnetiles and everything that lets them build in a free-form.

thank you!
random3··on A third world engineer responds to “RISC-V: They should have known better”
Can you list the actual chips you’re referring to and additional sources to follow? I’ve finally started playing with ESP32 and recently getting curious about the smallest possible things out there. Also
random3··on Cultivating a state of mind where new ideas are born (2023)
There are a few mathematicians that have analyzed and wrote about their process. A recent (IMO) good writing on the subject is David Bessis' "Mathematica" (I found this review https://siliconreckoner.substack.com/p/review-of-mathematica... which I haven't had a chance to fully read). It covers both a personal perspective as well as examples from Grothendieck, Descartes and others.

Having had the opportunity to have ideas and pursue them extensively as a corporate employee, startup founder, and independent researchers, all I can say is that there seems to be a violent agreement of how stuff actually happens and that it's almost never fully made possible in either industry or academia. It's like a living irony.

For a deeper treatment of the broader subject - one of the most cited books is the "The Structure of Scientific Revolutions"

random3··on Engineers will do anything to avoid learning from history
Yes. This. Also I don't think most software engineers are CS majors, either :)
random3··on AI has access to a vastly larger working memory than the human brain
if you take any system and break it down you get to simple building blocks (like memory). Then you claim that it isn't "outthinking" but "out remembering". Sorry, but what do you think the brain is doing? Not using memory? Especially working memory. How about frequency, brain is operating in Hz whereas most processors are in GHz, etc.

Finally if we were to think in terms of a proper memory/latency hierarchy, what's a Model + CPU's equivalent of working memory? Registers? L1 cache?

random3··on Engineers will do anything to avoid learning from history
I wrote FDM instead of additive manufacturing. I'm referring to is actually in SLS (selective laser sintering) space (which is what you refer as PBF?)

What I'm seeing is that companies like Formlabs (plastics) and divergent (metal) are changing the game and you have car parts to car engines to rocket engines being 3d printed.

See my other comment above for more links, but things seem to be changing fast in manufacturing.

Edit:

I think this quote sums the point though:

“With the increased throughput and decreased costs, Fuse X1 has completely changed our perspective on what kinds of projects our lab can support versus what we would have traditionally moved to an injection mold.” Cody Jepsen, Engineering Technician, Additive Manufacturing at Tesla Giga NV

random3··on Engineers will do anything to avoid learning from history
I'm not building molds, but I'm actively researching the field in conjunction with my work. Based on what I'm seeing and reading things have changed in the last few years dramatically. Concretely in the selective laser sintering (SLS) Formlabs is redefining small-scale manufacturing. But don't get distracted by the "small-scale". It's a bit like how small servers replaced mainframes. Production lines are getting replaced by much more versatile alternatives.

Formlabs recently launched a $80K industrial-grade machine that works better than it's $500K alternatives.

https://formlabs.com/blog/announcing-fuse-x1-industrial-sls/ https://formlabs.com/blog/diy-injection-molding/ https://www.youtube.com/watch?v=0TvjUVdn3YQ&t=2586s

Formlabs is used by Tesla to print car parts to Ukraine to print drones.

The thing about SLS is that it works with metal too. So you have startups like Divergent (recently raised $290M) in LA printing car engines https://www.latimes.com/b2b/space-tech/story/2026-06-23/dive...

Note that rocket engines are 3d printed too from SpaceX to India's Sky Roots https://www.selfcad.com/blog/how-spacex-uses-additive-manufa... https://3dprintingindustry.com/news/skyroots-vikram-1-reache...

So is injection molding more effective than additive manufacturing? This question is a bit like "no more interesting than the question of whether a submarine can swim".

But while you have metal at industrial scale you have "desktop" metal printers for ~$10K https://all3dp.com/4/first-look-at-the-scrap-1-desktop-metal...

random3··on Engineers will do anything to avoid learning from history
Yet this is part correct, part wrong. Indeed every industry has some unique challenges that are not directly solvable. However, while a cast is absurdly expensive, the problem is being solved in large part by software in the FDM (3D printing) space and it's changing how things are built.

edit: this doesn't invalidate the OP thesis, which I strongly agree with. Except that it's not just engineers, this is a more general thing across many fields.

random3··on RISC-V: They Should Have Known Better
Yet it's royalty-free and good enough for Espressif (maker of ESP32) to move exclusively to the RISC V open-source instruction set architecture [1].

"Good enough ISA plus zero licensing cost" beats "perfect ISA plus royalties" in the embedded space.

Also, let's not forget that the reason the world is built on the von Neumann architecture is that it was made available for free.

random3··on New Lower and Upper Bounds for the Grothendieck Constant
This makes no sense. It would be smart enough to understand but not enough to explain it, or are you assuming the human brain can’t comprehend the world by default?
random3··on We eliminated 1,400 CVEs in NanoClaw's container images
It’s like it’s made of CVEs. First 50-100 should be a good sign if it’s cleaner to start over.

random3··on Zed DeltaDB
I think conceptually, the deltas are exactly the type of “basics” Zed is built on.
random3··on Gemini Robotics 2 brings whole body intelligence to robots
Cortical Labs has been doing work in this area. They had a Doom demo a while ago. I think it's a matter of tradeoffs. Perhaps you'd have biological version as a versatile all-around thing, but many tasks don't require that so likely the tin variants are more durable for many tasks. Also, in terms of reasoning, the brain bandwidth is very low and high latency so there are advantages to silicon chips there.

It's interesting to learn actuators are "behind". I kept seeing cool stuff in the 3D printing space and thought there's a lot of progress. I'd love to learn more.

random3··on Logic for Programmers
Ha! Me too - my colleague/friend had a philosophy/political science degree. He was also the funniest person I’ve worked with.

Given the volume of text philosophy wrangles, I’m not surprised TAOCP was casual =))

random3··on Canceling "Hey"
Something I was told when started building in fintech was that the laws are in such a way that its impossible to be 100% compliant in every interpretation.

The law is huge, complex and can often have conflicting aspects.

This is assumed by some to be "by design". When the law is such that everyone is breaking it, then the power shifts to whoever can bring people in "front of the law".

So, in every case with strong beliefs such as yours, IMMV and it's easy to voice an opinion when you feel "not in target".
