jshen··on Rust off Rails: The opinionated web stack for the AI era
If you can't take the time to write me a hand written note, I don't know why I should bother reading it.

You are picking an arbitrary thing that isn't the substance of the work, the styling of a page, and insisting it matters. Seems odd.

jshen··on Rust off Rails: The opinionated web stack for the AI era
Everything anyone does comes with resource constraints. Does everything warrant a custom designed web page?
jshen··on Yes, and
Rugs aren't live running systems, so not analogous.
jshen··on Douglas Hofstadter: Analogy as the Core of Cognition [video]
This is very similar to George Lakoff's work. https://en.wikipedia.org/wiki/George_Lakoff

A good place to start for anyone that is interested is his book Metaphor's We Live By.

Sure, but that's not generational wealth.
jshen··on Nvidia's $750B in Deals Reignite Circular AI Fears
Yeah, I would also assume that anyone talking about VTI wouldn't try to time the market, but that's what he was talking about so :shrug:
jshen··on Nvidia's $750B in Deals Reignite Circular AI Fears
First, don't park it in actual cash or you'll lose value to inflation which is currently running high. At a minimum put it in treasuries.

Second, trying to time the market is almost always a suboptimal strategy. The question is when will you likely need the money? If you won't need it for 10 years or more, keep it in index funds. Otherwise, treasuries.

jshen··on Kimi K3 Is Competitive with Fable; Kimi K3 and Fable Is SoTA
This is the most naive comment I've read in a long time.
jshen··on Kimi K3 Is Competitive with Fable; Kimi K3 and Fable Is SoTA
This isn't true unless you're limiting your reference point to Trump's second term.
jshen··on Building on ATProto
If the primary user concern is "all data is public", then the utility of ATProto is extremely narrow and will likely lose to something with a different philosophy.

Is kimi making a profit? How subsidized is it by the Chinese government?
jshen··on Grok 4.5
Let's compare concrete and equivalent people or institutions. I'll nominate Elon to represent "right wing philosophy" since this is a conversation about grok. What's an equivalent, in terms of importance/stature, that you'd nominate to represent "left wing philosophy". From there we can compare the accuracy and truth seeking of both. Warning, Elon has a terrible track record on this front.
jshen··on Resetting Xbox
It's more like evolution through natural selection. If you can buy a treasury that returns 3.6%, you will NOT invest money in a business that has more risk, is only returning 3%, and has no believable growth story. Even worse, if you own shares in that company, you will sell them and shift the investment dollars to something with better returns or better chance for growth.

It's this competition that leads to prosperity, the alternative is central planning which leads to poverty.

jshen··on Resetting Xbox
That's a 3% margin which is unsustainable. It's less return than you can get from buying treasuries, which means that if they don't improve it they will go out of business.
jshen··on Stack Overflow’s forum is dead but the company’s still kicking
thanks, that's exactly what I was imagining.

We may need to create a community driven version of SO. Hard for it to be a successful business these days.
jshen··on Use boring languages with LLMs
Except for the part where he says that he found Go infuriating to use as a developer prior to LLMs.
jshen··on Use boring languages with LLMs
> This is annoying but only needs to be solved once at the start, either by the LLM or the human guiding it. A single prompt of "Set up a uv project in this directory with Python 3.13" is enough that it's never an issue again for that repo.

This isn't true. I'm mostly using python and UV with claude and it periodically decides to try to run scripts directly instead of using UV.

jshen··on 50K Tahoe residents need power as utility eyes redirecting lines to data centers
The far left tends to treat humans as essentially good and plastic — corrupted by unjust systems, but redeemable once those systems are dismantled. Remove capitalism, hierarchy, scarcity, and people will naturally cooperate. The far right tends toward a Hobbesian view — humans are greedy and lazy by default. Without the discipline, consequences, and hierarchy, civilization unravels. Hence “if you tax people more they’ll stop working.”

Both are cartoon versions of something real, and both fail in predictable ways. The more honest picture comes from behavioral economics and evolutionary psychology: humans are neither blank slates nor rational maximizers. We’re a messy bundle of cooperative instincts and tribal ones, capable of extraordinary generosity within in-groups and breathtaking cruelty toward out-groups. Our “goodness” has always been conditional and contextual.

What really undermines the anarchist vision specifically isn’t that people are evil — it’s that they’re biased and self-deceiving in systematic ways. There’s a well-replicated finding that when you ask members of a team to estimate their individual contribution to a group outcome, the percentages sum to well over 100%. Everyone genuinely believes they pulled more than their weight. This isn’t malice — it’s a predictable artifact of how memory and attention work. We have more access to our own effort than to others’, so we weight it more heavily.

The practical consequence of this is underappreciated: it means that even in a community of genuinely well-meaning people with no bad actors, you’ll still get persistent grievance and conflict, because everyone will sincerely believe they’re being shortchanged. This isn’t a solvable problem with better norms or more transparency — it’s baked into human cognition.

pretty sure humans had hierarchy from the beginning.
jshen··on 50K Tahoe residents need power as utility eyes redirecting lines to data centers
I think it's people that do that, not capitalism. This happens in every system that has existed in human history.
jshen··on California leaders report four to six weeks worth of gasoline and diesel supply
You didn't really address his main point. Will this lead to higher levels of pollution that will have real health consequences? Oddly you suggest it's not valid to raise concerns around health consequences.
jshen··on 40% of lost calories globally are from beef, needing 33 cal of feed per 1 cal
I honestly can't tell what conclusion you want us to draw? The vast majority of cows raise for agriculture are not raised in the ways you describe. Beef is the leading cause of deforestation in the rainforest!
jshen··on 40% of lost calories globally are from beef, needing 33 cal of feed per 1 cal
You can absolutely survive and thrive on a vegetarian diet, and there is decent evidence suggesting you're health will be better.
jshen··on 40% of lost calories globally are from beef, needing 33 cal of feed per 1 cal
what?!?!
jshen··on 40% of lost calories globally are from beef, needing 33 cal of feed per 1 cal
It's the leading cause of deforestation which is a major factor in climate change. It also is a major contributor to climate change for other reasons. Since you mentioned energy, it's also much less energy efficient.

Isn't this something to care about?

If you're trying to link clang, this laptop is not for you. It's for people that would consider a chromebook for their use case.

What model did you use? Curious if something like Opus 4.6 does a better job.
