prpl··on Apple routed a graphite pipe through the iPhone Duo's hinge to dissipate heat
Big E Engineering vs little e engineering.

IMO the barriers to entry are just much different, and it’s reflecting in the workforce. There’s cultural differences too, but I think the education differences is the biggest cause.

prpl··on AI is a tool and using it well takes skill
Palantir guy would say neurodivergence
prpl··on Build your own decision model
AIaaS
prpl··on DuckDB Ducklake
What latencies were you targeting?
prpl··on Yes, and
I feel like the better value will be in physical sciences where you are also solving problems, sometimes concretely and sometimes abstractly, or even philosophy.
prpl··on JetBrains reports revenue growth, net financial loss for 2025
Did you learn english or C first?
prpl··on GPT-6 UltraFast
4.8 at 10k tokens a second would be more groundbreaking than a Opus 6 IMO.
prpl··on We're gonna need a lot more mathematicians
Terence Tao did NOT say that. Amit Sahai did. Maybe you are just being less careful?
prpl··on The Price of Intelligence Is Falling Rapidly
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.

prpl··on Salesforce Global Outage
a few things are global (login service) to some extent, just as AWS places several such things in us-east-1
prpl··on US Customs supervisor busted for stealing hardware from Homeland Security PCs
We’re talking about ~’94 here…
prpl··on Cherenkov Radiation - traveling faster than light
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).

prpl··on GPT-6 Astra
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.

prpl··on VMs won't contain cyber-capable agents
A SOTA model at 10k will be materially different, even the model is 6 months old.
prpl··on Malicious Rust crate Arrayref runs a build-time payload
I have been working on a cross platform way of sandboxing without a VM:

prpl··on Humans missed 1 in 3 threats approving AI agent commands across 40k game runs
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
prpl··on Humans missed 1 in 3 threats approving AI agent commands across 40k game runs
For one, I’ve been working on a generic sandbox environment

github.com/brianv0/formwork

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.

prpl··on There Will Come Soft Rains (1950) [pdf]
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)

prpl··on Boris Cherny on Trying to Get Claude Code to Rewrite the Claude App
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.

prpl··on NSF pilots 4-year PhDs with industry research placements
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.

prpl··on JEP 540: Simple JSON API (Now in Incubator)
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)
prpl··on New York becomes the first state to impose a data center moratorium
Are you being serious or sarcastic?
prpl··on Knoppix
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.
prpl··on Looking Ahead to Postgres 19
Salesforce runs Salesforce on postgres with LSM:

prpl··on Israel targeted Gaza children resulting in genocide, UN inquiry says
you've had an account for four years, and _this_ is your comment?
prpl··on Job application asked for my SAT scores
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.

prpl··on AI outperforms law professors in Stanford Law study
there’s really no limit to how many times and ways you can review something with AI, except dollars.
prpl··on Rubin Tracks Skyscraper-Size Asteroids and Failed Supernovas
They are not all filtered early nor are they necessarily missing from images. The data can be embargoed until orbits change effectively.
prpl··on Microsoft Copilot Cowork Exfiltrates Files
Right, people haven’t internalized that these are really just scripts in natural language.
prpl··on 'AI washing': firms are scrambling to rebrand themselves as tech-focused
Oracle is the hilarious version of this -

9i - "internet"

10g - "grid"

11g - "also grid"

12c - "cloud"

26ai - "ai"

various other examples. One really annoying thing is this has also happened in open source projects too - generic things that, sure, help out with AI tasks are now "AI" things.
