I’d happily take Opus 4.8 xhigh at a reliable 10k tokens per second over oversubscribed SOTA models.

At some point this will probably happen, but we’re not quite there yet.

a few things are global (login service) to some extent, just as AWS places several such things in us-east-1

Not just gamma rays, cosmic rays too, although they filter the UV and are targeting nitrogen fluorescence and catch the cerenkov overlap. I’m sure there’s many people here who have worked on them.

I worked on HiRes/Telescope Array in Utah (Not CTA).

Not sure the thrust of your comment, but what is really going on is just novelty seeking to get a bit of a dopamine rush, which slides into creativity.

It all comes down to dopamine at the end of the day.

A SOTA model at 10k will be materially different, even the model is 6 months old.

sure it’s not tricky. But everybody does it different and OpenAI couldn’t even be bothered to do it right when benchmarking their models

For one, I’ve been working on a generic sandbox environment

You should be easily able to hide/lock down files, network, and MCP tools from an agent and it shouldn’t be up to the agent.

It’s been a very long time, but I read Alas, Babylon in middle school.

I remember aspects of their modern existence also being problematic (IIRC a house in florida with lots of windows doesn’t fare well without AC)

I’ve been formalizing behaviors to requirements and building more end to end tests to verify them. In reality, every requirement needs a verification element. Secondly, building traceability in your unit/integration tests helps “keep it honest” about how much it has built and verified.

Mostly I’m borrowing heavily from model based systems engineering and adapting it to some form of constitutional spec driven development.

New comment by prpl in "NSF pilots 4-year PhDs with industry research placements"

prpl — Thu, 30 Jul 2026 06:15:58 +0000

My impression is that many of the indian engineering schools are some form of trade school and it shows. A lot of people are very good at churning out things, but they vastly prefer to use well defined tools for their trade and do a lot of work impassionately. Taking the creative path or even reflecting on failures isn’t natural.

On the other side of things, you have PhDs coming out of the US with too many ideas and the inability to deal with basics such as sprint planning and CI/CD.

Not sure if this will help, but I would love it for the Colleges of Sciences peoples instead of a postdoc.

Yeah you could go with just Number though, and then keep almost everything a BigInteger/BigDecimal under the covers (or dynamically choose the correct class)

I built a 40 (later 80) node cluster with clusterknoppix ~2006 to run a bunch of physics simulations off of old library computers after I replaced a bunch of PSU fans. Kept my cubicle toasty until we moved them into a random subterranean room I think was used for some early nuclear research at university.

New comment by prpl in "Job application asked for my SAT scores"

prpl — Mon, 22 Jun 2026 22:16:51 +0000

SAT isn’t an IQ test, and probably all sorts of people took it before they had cultural awareness or a diagnosis that would have lead to different testing conditions had it been taken after diagnosis, let alone the fact that test scores are not comparable.

GPAs similarly not comparable over large time ranges, schools, or degrees without normalization you can’t get.

there’s really no limit to how many times and ways you can review something with AI, except dollars.

They are not all filtered early nor are they necessarily missing from images. The data can be embargoed until orbits change effectively.
