dextrous··on Research acceleration: The view inside OpenAI

dextrous··on De-Brainrot Vacations
Thanks for this post, I can truly relate. Some thoughts from a 50+ year old genx guy (EE/CS) who’s worked to stay current and keep a sharp mind in the face of these challenges plus the inevitable age-related decline:

- regular exercise has incredible benefits for the body+ mind (and the attitude that directs it). Biggest impact of everything on this list.

- Side projects that involve actual doing and not just study. e.g. I spent some money on gear for embedded development and am doing things that involve physical things and using my hands and making gadgets … phone is out of the picture while in the lab.

- Ironically, using LLMs for reviewing and refreshing knowledge you once had but now has gaps is amazing. I spend a bunch of my phone time now having in-depth chats where I know what I’m talking about to a large degree, but the LLM is helping me fill in gaps and then quizzing me on concepts and I know that the things it’s telling me are solid due to my background, then I go check, etc. A really good way to do super focused study to reload a field back into your brain. Might as well take advantage of the fact that they stole all of the world books.

- Write things down! After reviewing, do some problems with pencil and pad. After studying, doing a problem on pencil and paper is actually daunting, but then grooving through a few problems actually makes you realize you know the stuff again! And using an expensive Ampad notebook and nice mech pencil is a great sensory experience.

dextrous··on Research acceleration: The view inside OpenAI
See Amodei’s comments regarding Iain M Banks’s Culture, his goal is benevolent machine rule. I suspect many HN folks would agree; I, for one, was rooting for the Iridians.
dextrous··on Research acceleration: The view inside OpenAI
> If it is done responsibly, we believe automated AI research will yield models that directly enhance human welfare and advance OpenAI’s mission.

That’s what I call a load-bearing “if”.

I do not trust OpenAI or other hyperscalars to do this responsibly; and IMO it will be very difficult for government-led efforts not to result in a technocracy where a cabal of AI companies are pulling the strings. Dark times lie ahead, especially when you consider the shrinkage of true source material on the internet and the stranglehold these companies will have on information; and these AI CEOs to me are reminiscent of 19th century robber barons, none seem trustworthy.

Beautiful work, thanks for sharing!
dextrous··on Artemis II is competency porn
I agree. Even though I thought this mission was interesting, to me the article massively overstates everything. NASA and the crew is SO amazingly competent, the world in recent years is SO totally devoid of competency, everyone has been thirsting for the sense of AWE that we are ALL feeling (or should be feeling now, let me list the reasons!), etc.

To me, this was irritating. True competency and things that inspire real awe encapsulate “res ipsa loquitur” — they speak for themselves. Having some internet influencer try to hype me into getting awed, and implying that “we all” are feeling a certain way as she channels our collective zeitgeist is tiresome.

And personally, IMO although the mission was nice, it wasn’t groundbreaking technically or particularly awe-inspiring.

Ironically, I left feeling a tiny bit disappointed: if everyone is truly thinking this mission is the height of awesomeness or competency, we have a low-ish bar.

I bet that when the old-timers with their starched white shirts, pocket protectors, and horn-rimmed glasses that did the 60s missions got together to watch 2026 Artemis they privately had a good laugh about how little state-of-the-art has progressed.

dextrous··on Ask HN: Please restrict new accounts from posting
One way that I could imagine a human-only HN could evolve in the coming AI wasteland: motivated individuals join small local groups and are validated face-to-face at meet-ups. Local trusted leads gatekeep their chapter’s posts, and this scalable moderation works up the tree. Bad leaves get culled out reasonably fast, maybe there’s some controls at the top level that let you see more content “lower down the tree” if you’re ok with lower SNR. Latency to get a post widely distributed grows but I don’t see that as a massive problem.
dextrous··on Tell HN: I'm 60 years old. Claude Code has re-ignited a passion
Fully agree: I believe my decades of software engineering experience definitely help me fly LLM tools better than less experienced folks.

But the much more interesting question to me: as LLM coding becomes the norm, does it drive the cost of self or small-company generated software to 0?

Like many SW architects/engineers my not-so-developed work-in-retirement plan is to assemble a small team of people I’ve loved working with over the years, start an LLC, and try to make a reasonable (not posh) living doing what we love: making software to solve problems.

On the one hand, it’s clear LLM coding can accelerate and amplify our efforts, but alternately there’s many people claiming there’s no possibility of a moat, your solution/innovation can be cloned in a matter of days … ie. the value of your software is exactly 0.

Not sure which future will be closer to reality. A backup plan that seems reasonable in the 0-value case is to focus our effort on creating actual physical gadgets and systems in the embedded realm, which conceivably can be designed and prototyped by a small team… It seems like these would still be valuable.

dextrous··on Cognitive Debt: When Velocity Exceeds Comprehension
My team has experienced this over the past 6 months for sure.

The core of the article is “ AI-assisted development potentially short-circuits this replenishment mechanism. If new engineers can generate working modifications without developing deep comprehension, they never form the tacit knowledge that would traditionally accumulate. The organization loses knowledge not just through attrition but through insufficient formation.”

But is it possible this phenomenon is transient?

Isn’t part of the presumed value add of LLM coding agents in the meta-realm around coding; e.g. that well-structured human+LLM generated code (green field in particular) will be organized in such a way that the human will not have to develop deep comprehension until needed (e.g. for bug fix/optimization) and then only for a working set of the code, with the LLM bringing the person up to speed on the working set in question and also providing the architectural context to frame the working set properly?

dextrous··on How to effectively write quality code with AI
Agree on data value, but as mentioned above I am not yet buying the “everything will be instantly copyable and so any solution is instantly commodity” argument … crud web-app sure, something with significant back-end complexity or a multi-service systems level solution, not so much. Perhaps optimistic, admittedly. Cheers.
dextrous··on How to effectively write quality code with AI
“And when everyone’s super, no one will be”.

Fair point, but my hope is that the creativity involved in deciding what to build, with the choice informed by engineering experience (the project/value will not be obvious to everyone) will allow differentiation.

dextrous··on How to effectively write quality code with AI
After a multi-decade career that spanned what is rapidly seeming like the golden age of software development, I have two emotions: first gratefulness; second a mixture of resignation, maudlin reflection, and bitterness that I am fighting hard to resist.

As someone who’s always wanted to “get home and code something on my own”, I do have a glimmer of hope that I wonder if others share. I’ve worked extensively with Claude and there’s no question I am now a high velocity “builder” and my broad experience has some value here. I am sad that I won’t be able to deeply look at all the code I am producing, but I am making sure the LLM and I structure things so that I could eventually dig in to modules if needed (unlikely to happen I suppose).

Anyway, my hope/question: if I embrace my new role as fast system builder and I am creative in producing systems that solve real problems “first”, is there a path to making that a career (I.e. 4 friends and I cranking out real production software that’s filling a real niche)? There must be some way for this to succeed —- I am not yet buying the “everything will be instantly copyable and so any solution is instantly commodity” argument. If that’s true, then there is no hope. I am still in shape, though, so going pro in pickleball is always an option, ha ha.

Thanks very much for this awesome write up! It’s detailed labor-of-love work like this that helps others (like me!) make great jumps in learning. So appreciated.
dextrous··on 4k NASA employees opt to leave agency through deferred resignation program
Politics aside, according to a pretty comprehensive study (118 missions) it does seem that SpaceX is much more efficient than NASA [1]. Data like this would suggest privatization of space missions is a good idea. Maybe this conclusion is biased somehow, or perhaps the purpose of a dedicated govt org is different in some way that justifies its budget and scope despite the difference in efficiency?

dextrous··on SOFA - Start Often Finish rArely
SOFA works just fine with marriage, just tweak the vows:

“… to have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and to cherish, until I feel like this is done and want to move on. And done is when I say it’s done.”

There won’t be a dry eye in the house!

dextrous··on Embedded Rust in Production?
I am a C/C++ dev learning Rust on my own, and enjoying it. I am finally starting to enjoy the jiu jitsu match with the compiler/borrow-checker and the warm “my code is safe” afterglow … but I have a question for the more experienced Rust devs out there, particularly in light of the OP’s observation about “lots of unsafe” in the Rust embedded realm (which makes sense).

If your Rust project leans heavily on unsafe code and/or many libraries that use lots of unsafe, then aren’t you fooling yourself to some degree; i.e. trusting that the unsafe code you write or that written by the 10 other people who wrote the unsafe libs you’re using is ok? Seems like that tosses some cold water on the warm afterglow.

dextrous··on The Simple Guide to Building and Breaking Habits
“List six habits you wish to adopt, assign them to different times of the day, and aim to consistently perform at least four.”

SIX? Um, how about we start with, like, one?

That aside, a concise article with good advice IMO, but I would add “find a partner and be accountable”, especially for eliminating addictive / tempting bad habits or replacing them with good ones.

dextrous··on Webb captures iconic Horsehead Nebula in unprecedented detail
I am reminded of David’s song in Psalm 19 … It’s amazing to me how in the thousands of years since he wrote these words, we’ve still only scratched the surface of observing the beauty and depth of creation.

The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they reveal knowledge. They have no speech, they use no words; no sound is heard from them. Yet their voice goes out into all the earth, their words to the ends of the world.

dextrous··on You Are Beautiful (to at least some people) (2015)
I can totally believe the beauty-in-the-eye-of-beholder thesis, and it’s encouraging to think that I just need to find the 3% of people that will think I’m gorgeous. But it would be interesting to run the numbers and test the following thesis: are these people all the ones that are on average way uglier than me? I’m betting they are … and now the Tubes song “She’s a Beauty” is playing in my head…
