    I'm also at a startup. My workflow is similar but I have Fable 5 xhigh drive the whole thing: it gets Codex CLI installed in its environment with an API key, and it's instructed to…

    Most evidence indicates that OPT graduates create more jobs for US-born workers through business formation than they "consume," so this change would get us further from full employ…

    Like, buy and set up the physical hardware? I cba with that. Plus the hardware you want for LoRA (the type but especially the quantity) is different than what you want for inferenc…

    Thinky's main commercial product AFAIK is Tinker [0] - companies pay them to host their fine-tuning workloads and then the resulting fine-tuned models. I don't know if this is a go…

    I assume this is ~equivalent to ultracode in Claude Code, which can deploy a tree of hundreds of nested subagents and was just released experimentally 5 weeks ago IIRC.

    It's still just a bad answer across the board. Having opinions and being able to articulate and defend them clearly is itself an extremely important hiring signal regardless of a c…

    For comparison, I live in SF and am low-risk on all the dimensions you'd expect on HN, and I pay $100/month for non-owner coverage with similar limits - i.e., I don't own a car and…

    Not really. There are clearly diminishing marginal returns, so it's likely that the first $2,400/engineer/year adds >>$2,400 of value, even if 18,001st $/engineer/year adds <$1 of …

    I thought I was so clever for buying one of those things for like $190 and putting Lubuntu on it to make it usable. It worked - but the joke was still on me when it died a year lat…

    (Disclosure, I'm a former OpenAI employee and current shareholder.) I have two qualms with this deal. First, Sam's tweet [0] reads as if this deal does not disallow autonomous weap…

    It's both - it's clearly at least partly for moral reasons that they're even in the negotiation that they need leverage for.

    It's true that a volatile environment in general is good for certain types of investment banking business, including facilitating this trade. I nevertheless think it's unlikely - h…

    Fixed the “majority” claim. I think a competent opposition party would be great for the US. But regardless of the candidate, US voters had three clear choices in the 2024 President…

    I wouldn’t put anything past them, but my impression is that they were just acting as a middleman for this transaction and taking a fee, rather than making a directional bet one wa…

    I don’t see how constitutional changes would help. The constitution already creates separation of powers, limits on executive authority, and procedures for removing an unfit presid…

    A temporary win for the taxi lobby, though I expect this will be reversed one way or another in the next year or two. Still a sad outcome for now. People will die because of this d…

    I don't follow. The fertility rate has decreased significantly for US-born women of every race and ethnicity since the 1990s. I couldn't quickly find good stats on trend in birth c…
