rubidium··on AI-generated posters don’t have to be horrible
It’s the same cultural response as the analog movement. The collective sense that everything Covid on stole our future, and AI is only making it worse.
rubidium··on Why I didn’t sign the Fields medallists’ letter
That’s quite unfair to Asimov. It’s not just selection bias.
rubidium··on Diplodocus, Long Thought Exclusively American, Turns Up in Spain
I would think so yes. But not an authority on this.

The map is super cool though. Makes you think of the earth as something still aging since it looks clearly “earth” but with major differences.

rubidium··on Why I didn’t sign the Fields medallists’ letter
Read “the feel of power” by Asimov. Written 1958. Very prescient.
rubidium··on Don't let anyone take away your big box of cables
I hope you never have to work with serial D9 cables. The variation of pinouts for legacy equipment is massive! Pretty sure every theoretical variation became some standard.
rubidium··on Transcribe.cpp
Yea I’m looking local hosted transcription and translation with diarization of 2 (or more ) speakers. This is to speed up collaborative technical work between two teams who speak different languages where want all local processing (assume no cloud access).
rubidium··on Transcribe.cpp
Any that also support translation? How much harder/ easier of a problem is local translation compared to transcription?
rubidium··on OpenPrinter
99% of this is the printhead and the ink formulation. Assuming you use generic off the shelf solutions for those two components you’re set. All the printer companies do their lock in at the firmware and software layer.
rubidium··on ArXiv's Next Chapter
I did when I was in academia. Would open each day and check what new papers were in my field. It was fun, and I learned a ton.

I kept it up out of habit for a year after grad school. Then moved on.

rubidium··on Tell HN: I'm 60 years old. Claude Code has re-ignited a passion
And the biggest thing is that: software the way we want is much easier. No ads. No monthly cost.
rubidium··on Ask HN: Have top AI research institutions just given up on the idea of safety?
You’ve not accounted for the danger of necrotizing bureaucratic systems. Put these LLM drones in enough places and everything wills stagnate.

It’s effectively the start to Asimovs Foundation.

rubidium··on Evidence of the bouba-kiki effect in naïve baby chicks
I do agree my skepticism level rises extremely high in any experimental psychology experiment. There’s just so many ways to bias results, in addition to “do enough experiments and one of them will get a statistically unlikely result” problem.

This group does a lot like this https://www.dpg.unipd.it/en/compcog/publications … so that’s tempting to think they keep trying things until something odd happens (kind of like physicists who look for 5th forces… eventually they find something odd but often it’s just an experimental issue they need to understand further).

rubidium··on Adoption of EVs tied to real-world reductions in air pollution: study
I did daily (old station wagon in the rear facing seat), as well as school buses. Kindof liked the smell in moderation as a kid.

Still in favor of EVs, just a curiosity that this is so negative for you.

rubidium··on Purdue blocks admission of many Chinese grad students in unwritten policy
It’s great place for grad school. Very little to do other than study and lab work. Play soccer with the grad students, float on the river in the summer, shoot potato gun cannons in corn fields, but otherwise there’s nothing better to do than work on a PhD.

I’d recommend it for grad school. But then yea time to move on.

rubidium··on The suck is why we're here
This is the attitude of someone who uses hand tools when power tools are available. Yes you loose the personal touch but also loose the potential efficiency. Still need to measure twice and cut once though.
rubidium··on Ask HN: How do I bridge the gap between PhD and SWE experiences?
Make a list of the most interesting companies / areas you want to work in from a scientific perspective

Cold call or get introductions to their R&D leaders (principal researcher /director / VP). While connecting to something they or their company did, ask for a coffee meeting or phone call to learn more about their company and how it works.

Use this to Network network network. At some point a job will appear with interviews. Chances are good it’s with a good manager as they’re the ones taking time to build good teams and talent.

rubidium··on Leak confirms OpenAI is preparing ads on ChatGPT for public roll out
Amazon prime video showed us that.

First no ads. Then ad free if you pay extra. Then “ad free” except half the shows have a “this show requires ads” bs and still have ads. Scummy flea ridden advertisers at their core.

rubidium··on Typst: A Possible LaTeX Replacement
You went to the wrong university :)
rubidium··on When the job search becomes impossible
It’s pretty much always who you know… at least to get a showing. It’s rare in history to find counter examples. And in a LLM fueled world it’s going to be more important.

Companies can improve by ensuring they don’t hire _because_ of whom someone knows. It should only ever let you get in the room to interview.

So practical advice of what to do: be human. Get to know people. Care. Your time to do this is not when you’re looking for a job, but when you’re in a job.

rubidium··on High Altitude Living – 8,000 ft and above (2021)
You have experience in 2 very different places demographically. High altitude may be on the list of factors but I would guess it’s pretty far down.

Boulder is a small college town of mostly affluent younger people. Memphis is an urban city in a hot climate that is older, poorer, and in the middle of the section of the US that has some of the worst health overall.

rubidium··on Claude’s memory architecture is the opposite of ChatGPT’s
I’ll be concerned when ex-Yelp “growth strategists” start showing up at OpenAI and leverage the same extortionist technics.
rubidium··on Everything you've been told about burnout is wrong
This is an engineering management hot take on how to motivate a team. It’s not realistically covering burnout, human psychology, or what makes us human and tick. It’s just giving management advice with a flashy title.

It’s not necessarily bad advice (setting and celebrating milestone goals on a long project is good). But it’s also not applicable to most cases of disengagement from the important things in life (aka burnout).

rubidium··on Google has eliminated 35% of managers overseeing small teams in past year
When you become a good enough IC, “ As an engineer, I prefer to be managed and guided by someone who actually knows what I work on, preferably better than I know it.” is no longer reasonable. Then your managers role is to maximize your ability to make an impact by putting you in the right place/project.

As a manager of people who know far more about the things they do than I do, my goal is to assist and ensure in the right place (for them and the org). It’d be foolish for me to hire peons who know less than me.

rubidium··on Bring Back the Blue-Book Exam
I used them in graduate physics courses 2008-2010
rubidium··on California unemployment rises to 5.5%, worst in the U.S. as tech falters
For people I talk, it is the end of ZIRP that caused it. ZIRP ended in April 2022.

Even as interest rates went up the VCs still had committed funds to distribute for a year to 18 months. Then the biotechs had runway for 1-2 years from that. Now that’s all gone, and they can’t raise their next series. In the meantime, C&GT plus synbio is recently having a lower win rate than hoped for.

That plus all the money that is there is all going to AI companies due to the shorter time to return / higher potential roic / hype.

rubidium··on California unemployment rises to 5.5%, worst in the U.S. as tech falters
Biotech is facing a huge downturn right now too.
rubidium··on Kodak says it might have to cease operations [updated]
Fujifilm succeeded at it (before Kodak tried). Interesting case study between the two companies.
rubidium··on Comparing baseball greats across eras, who comes out on top?
The overlap of statisticians and baseball fans is high (anecdotal).

Hypothesis 1: statisticians love good data sources, and with its many games, innings, and types of hits / pitches it’s a great source.

Hypothesis 2: makes you seem more interesting at dinner parties

hypothesis 3: a natural overlap of preferences

rubidium··on Show HN: I've been building an ERP for manufacturing for the last 3 years
I have no idea why you’re using icons for 13 things. Use words.
rubidium··on We built an air-gapped Jira alternative for regulated industries
They make it seem like a big deal. It’s pretty much how all software used to ship :)
