Congrats! Hope it's a good busy. I definitely wonder how some folks On Here manage to post so frequently, given that they're also fully employed. My days have never been so relaxed as to enable fully online behavior.

For a platform that believes in controlling your own experience and community moderation, @bsky.app could use a lot more speedbumps for preventing poor behavior

Enforcement of anti-brigading rules after the fact is a good thing, but features to control your experience are even better. (I feel like that's part of the notional platform philosophy anyway?)

I continue to think bsky should have speedbumps built into the design, e.g. - A modal warning if QTing a much smaller account - A modal warning if your reply seems extra-spicy - Configurable triggers that auto-close replies/quotes if you get too many interactions too fast etc.

Or to phrase it differently: Jensen cares more about NVIDIA's success than anything else in the world. If you work at NVIDIA, he expects the same from you. Whether or not that's a good trade is up to you! It's in many ways a very fun time, it's just also rather prone to burnout.

ajdecon @ajdecon.org · 28/09/2026
To be clear, I spent the majority of my career (so far) at NVIDIA. The company really is very good to its employees in terms of pay, benefits, time off, and even being human at work. The trade is that NVIDIA also demands a much higher level of focus while *at* work than most other workplaces.

* Re: influencing politics, NVIDIA does of course lobby the government, but seems to do so in very boring "business-friendly environment" ways

ajdecon @ajdecon.org · 28/09/2026
More seriously -- NVIDIA wants to be a company where you can "do your life's work", and I think that philosophy starts at the top. AFAICT, Jensen doesn't spend time fantasizing about AGI or trying to influence politics* or even buying toys. He just wants NVIDIA to be as successful as possible.

ajdecon @ajdecon.org · 28/09/2026
I mean of course Jensen cares about more than selling GPUs. NVIDIA also makes CPUs and network gear after all.

🤷‍♂️ don’t know how an interviewer can stop you (unless in person, and the smell gives you away!) but I don’t think it’s an edge case important enough to police folks’ hydration in interviews

ajdecon @ajdecon.org · 27/09/2026
Because this discourse is still going, I feel like I should say: If I’m interviewing you, feel free to have an iced coffee. Or a regular coffee. Or a bottle of water. Or whatever (non-intoxicating) beverage or snack helps you perform. Treat people like adults who can manage their needs, please.

Those histories are also honestly helpful to practitioners, given how often engineering is historically contingent. So frequently, “why does X work that way?” traces back to “because this team 30 years ago made a decision based on where they trained or what was cheapest at the time”
021
ajdecon @ajdecon.org · 27/09/2026
Entirely separate from the quotes on general liberal arts, I’m really sad about how little science/eng degrees teach the history of the fields themselves. The histories of fields like physics, computing, structural engineering, genetics, and so on are all fascinating!

ajdecon @ajdecon.org · 27/09/2026
That seems like it should be an additional course rather than replacing the existing topics, to be clear. Everyday engineering ethics is still probably the most relevant bit for most working professionals. Which leads to the increasing problem of “so many required courses”… etc
020
ajdecon @ajdecon.org · 27/09/2026
AFAICT, most undergrad engineering ethics education focuses on “nuts and bolts” topics. E.g., avoid conflicts of interest, don’t compromise safety to reduce cost, no bribes, that kind of thing. Those are all important! But it does feel like more coverage of societal impact is needed these days.

There is very little as frustrating in (online) chess, as mis-clicking a move badly, and then fightin a losing battle for the rest of the game. Literally had the phone slip in my hand and moved my queen into the worst possible position. 😮‍💨

This is a good description of something that frustrates me regularly. So many folks seem to ignore the actual goals of whatever effort they’re part of, in favor of applause from people they like.

I mean totally fair. TBH part of it also comes from the experience of using them. Better results if your input resembles talking to a person than machine instructions.

ajdecon @ajdecon.org · 25/09/2026
In certain cases, sure. I talk about code generation or text generation a lot. Tool use makes it awkward. “The LLM generated code which resulted in many web requests to search engines with keywords about trains”? Nah, the LLM went and researched trains.
110
ajdecon @ajdecon.org · 25/09/2026
This is basically where I am. If I say the LLM thought about something, that doesn’t mean I think it’s doing the same thing as a human. It’s just a lot less tedious than saying “the LLM appeared to process text about X in a way that produced a particular result”

*sigh* This is a very Jensen thing to say. He spends 16+ hours a day running NVIDIA, because to him it's the most fun thing he could be doing. This shows up in other interviews too. Of course he doesn't remember his zip code, he's restructured his life so he doesn't have to.

I’ve seen this happen in two-author situations at least. (Paper A has author A as first author, Paper B for B) Often it’s e.g. an experiment-focused paper and an analysis-focused paper, submitted to different journals. I haven’t personally seen it for larger numbers but feels possible 🤷‍♂️

I don’t disagree, but also it’s just exhausting to see so many people unwilling to acknowledge uncertainty.

What this says to me is that most datacenter regulations are more responsive to constituent sentiment (which is fair!) than to any specific DC build of concern. - 300+ datacenter bans or moratoriums in the US - Only 3 projects actually meaningfully impacted so far

It brings to mind the obsession with “gray goo” scenarios when nanotech was a big thing in science. Not so much a realistic scenario as “this would make an AMAZING sci-fi movie”.

IIRC, the Three Laws were basically a hook that Asimov used to write often-playful short stories about logic problems, and how to find loopholes in rules. Fun, but hardly the basis for serious safeguards on AI.

I would sincerely love to find actionable advice on this beyond “tell your parents to ask you about each interaction”. Even at the level of “ignore it all until you get a letter in the mail”, which *feels* right but may not be. My parents are fairly savvy, but I worry.
